Our fully revised Mercedes-Benz repair manuals are written by experts with hands-on experience, ensuring you have all the practical information you need to carry out full-scale servicing and DIY repairs.

ROnly hold the steering wheel by the rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when the driver front air bag inflates. R Adjust the front-passenger seat as far back as possible from the dashboard when the seat is occupied. R Occupants, especially children, should never place their bodies or lean their heads in the area of the door where the side impact air bag inflates.

This could result in serious injuries or death should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized child restraint, infant restraint or booster seat recommended for the size and weight of the child.

R Canada only: children under 12 years may only sit in the front-passenger seat if they are seated in a child restraint system which is compatible with BabySmart™ and approved by Mercedes-Benz. If the child restraint system is installed properly, the front-passenger front air bag is deactivated in conjunction with the BabySmart™ system installed in the vehicle. Otherwise, the child could be struck by the air bag when it inflates in a crash. This could lead to serious or fatal injuries. Failure to follow these instructions can result in severe injuries to you or other occupants.

If you sell your vehicle, it is important that you make the buyer aware of this safety information. Be sure to give the buyer this Operator's Manual.GWarning Accident research shows that the safest place for children in an automobile is in a rear seat. A side impact air bag related injury may occur if occupants, especially children, are not properly seated or restrained when next to a side impact air bag which needs to deploy rapidly in a side impact in order to do its job. To help avoid the possibility of injury, please follow these guidelines:(1)Always sit as upright as possible and use the seat belts properly. Make sure that children 12 years old and under use an appropriately sized child restraint, infant restraint, or booster seat recommended for the size and weight of the child.(2)Always wear seat belts properly. The air bags are only deployed if the airbag control unit detects the need for deployment.

Only in the event of such a situation will they provide their supplemental protection. The driver and passenger should always wear their seat belts. Otherwise, it is not possible for the air bags to provide their supplemental protection. In the event of other types of impacts and impacts below air bag deployment thresholds, air bags will not deploy. The driver and passengers will then be protected to the extent possible by a properly fastened seat belt. A properly fastened seat belt is also needed to provide the best possible protection in a rollover.

Air bags offer supplemental protection but are not a substitute for seat belts. All vehicle occupants must fasten their seat belts regardless of whether your vehicle is equipped with airbags or not. It is important for your safety and that of your passenger to have deployed air bags replaced and to have any malfunctioning air bags repaired. This will help to make sure the air bags continue to perform their protective function for the vehicle occupants in the event of a crash. Front air bags GWarning Observe 'Important safety notes' ( Y page 38). Occupant safety39SafetyBA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 39Z.

The front air bags increase protection for the driver's and front-passenger's head and chest. Driver's air bag: deploys in front of the steering wheel; front-passenger air bag; deploys in front of and above the glove box. They are deployed: Rin the event of certain frontal impacts Rif the system determines that air bag deployment can offer additional protection to that provided by the seat belt Rif the seat belt is fastened Rindependently of other air bags in the vehicle If the vehicle overturns, the front air bags are generally not deployed unless the system detects high vehicle deceleration in a longitudinal direction. Your vehicle has adaptive, two-stage front air bags. In the event of a collision, the air bag control unit evaluates the vehicle deceleration. When the first deployment threshold is reached, the front air bag is filled with enough propellant gas to reduce the risk of injuries.

The front air bag is fully deployed if a second deployment threshold is exceeded within a few milliseconds. Vehicles with OCS (USA only): front- passenger front air bag deployment is also influenced by the passenger's weight category as identified by the Occupant Classification System (OCS) (Y page 43). Vehicles with OCS (USA only): the lighter the passenger side occupant, the higher the vehicle deceleration rate required for second stage inflation of the front-passenger front air bag. In the second stage, the front air bags are inflated with the maximum amount of propellant gas available. In impact situations with deceleration or acceleration values lower than the vehicle deceleration or acceleration values preset in the system, the front air bags are not deployed.

You will then be protected by the seat belt.! Vehicles with BabySmart™ (Canada only): do not place any objects which weigh more than 20 lb (9 kg) on the front-passenger seat. This could cause the system to identify the seat as being occupied.

In the event of an accident, the restraint systems on the front-passenger side are triggered. Have restraint systems that have been triggered replaced. The front-passenger air bag will only deploy if: Rthe system, based on the OCS weight sensor readings, detects that the front- passenger seat is occupied (USA only).

Rthe 45 indicator lamp in the center console is not lit, USA: (Y page 43), Canada: (Y page 48). Rthe impact exceeds a preset deployment threshold. Driver's knee bag GWarning Observe 'Important safety notes' (Y page 38). 40Occupant safetySafety BA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 40.

Driver's knee bag: increases protection for the driver against the risk of: Rknee injuries Rthigh injuries Rlower leg injuries Driver's knee bag: inflates beneath the steering column. If the system determines that deployment of driver's knee bag: can offer additional protection to that provided by the seat belt in the event of a frontal impact, the system will deploy it together with the driver's front air bag. Driver's knee bag: operates best in conjunction with a properly positioned and fastened seat belt. Side impact air bags GWarning Observe 'Important safety notes' (Y page 38).

The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers. Improper repair work on the doors or the modification or addition of components to the doors create a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment.

Work on the doors must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center.

GWarning Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using seat covers or other seat coverings can cause a malfunction of the side impact air bags and/or the pelvis air bags.

Contact an authorized Mercedes-Benz Center for availability. When deployed, the side impact air bags offer additional protection for the thorax of the vehicle occupants on the side of the vehicle on which the impact occurs. However, they do not protect the: Rhead Rneck Rarms Example: Sedan Front side impact air bags: and rear side impact air bags; deploy next to the outer seat cushions.

Direction and determines that side impact air bag deployment can offer additional protection to that provided by the seat belt. The side impact air bags will not deploy in side impacts with deceleration rates which do not exceed the system's preset deployment thresholds for vehicle deceleration or acceleration. You will then be protected by the seat belt. Vehicles with OCS (USA only): if the OCS detects that the front-passenger seat is not occupied and the front-passenger seat belt is not fastened (the belt tongue is not engaged in the seat belt buckle), the side impact air bag on the front-passenger side will not deploy. The side impact air bag on the front- passenger side will deploy if the front- passenger seat belt is fastened, regardless of whether the front-passenger seat is occupied or not.!

Vehicles with BabySmart™ (Canada only): do not place any objects which weigh more than 20 lb (9 kg) on the front-passenger seat. This could cause the system to identify the seat as being occupied. In the event of an accident, the restraint systems on the front-passenger side are triggered.

Have restraint systems that have been triggered replaced. Pelvis air bags GWarning Observe 'Important safety notes' (Y page 38). GWarning Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using seat covers or other seat coverings can cause a malfunction of the side impact air bags and/or the pelvis air bags.

Contact an authorized Mercedes-Benz Center for availability. Pelvis air bag deployment enhances the level of protection of the vehicle occupants on the side of the vehicle on which the impact occurs. Pelvis air bags: deploy next to and below the outer seat cushions. They are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. In a side impact Rindependently of seat belt use Rindependently of the front air bags Rindependently of the Emergency Tensioning Devices The pelvis air bags are generally not deployed if the vehicle overturns, unless the system detects high vehicle deceleration or acceleration in a lateral direction and determines that they can offer additional protection to that provided by the seat belt. Pelvis air bags: will not deploy in side impacts with deceleration rates which do not exceed the system’s preset deployment thresholds for vehicle deceleration or acceleration.

You will then be protected by the seat belt. Vehicles with OCS (USA only): if the OCS detects that the front-passenger seat is not occupied and the front-passenger seat belt is not fastened (the belt tongue is not engaged in the seat belt buckle), the pelvis air bag on the front-passenger side will not deploy. The pelvis air bag on the front-passenger side will deploy if the front-passenger seat belt is fastened, regardless of whether the front- passenger seat is occupied or not. 42Occupant safetySafety BA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 42. Window curtain air bagsGWarning Observe 'Important safety notes' (Y page 38). The window curtain air bags enhance the level of protection for the head (but not chest or arms) of the vehicle occupants on the side of the vehicle on which the impact occurs. The window curtain air bags are integrated into the side of the roof frame and deploy in the area extending from the front door (A- pillar) to the rear door (C-pillar).

Example: Sedan Window curtain air bags: are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. In a side impact Rregardless of whether the front-passenger seat is occupied Rindependently of seat belt use Rif the vehicle overturns and the system determines that window curtain air bag deployment can offer additional protection to that provided by the seat belt Rindependently of the front air bags Window curtain air bags: will not deploy in impacts with deceleration rates which do not exceed the system’s preset deployment thresholds for vehicle deceleration or acceleration. You will then be protected by the seat belt. Occupant classification system (OCS) How the Occupant Classification System works The Occupant Classification System (OCS) is standard equipment in the USA. OCS categorizes the occupant on the front- passenger seat by means of a weight sensor. The front-passenger front air bag is automatically deactivated for certain weight categories. The respective status can be recognized by the 45 indicator lamp.

With the 45 indicator lamp illuminated, the front-passenger front air bag is deactivated. The system does not deactivate: Rthe side impact air bag Rthe pelvis air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices To be classified correctly, the front passenger must sit: Rwith the seat belt properly fastened Rin a position that is as upright as possible with the back against the seat backrest Rwith their feet on the floor If the front-passenger's weight is transferred to another object in the vehicle (e.g. By leaning on armrests), OCS may not be able to approximate the occupant's weight category.

If the front passenger seat, the seat cover, or the seat cushion are damaged, have the necessary repair work carried out at an authorized Mercedes-Benz Center. For reasons of safety, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. Both the driver and the front passenger should observe the 45 indicator lamp to determine whether or not the front passenger is positioned correctly. Occupant safety43SafetyBA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 43Z. GWarning If the 45 indicator lamp illuminates when an adult or someone larger than a small individual is in the front passenger seat, have the front passenger reposition himself or herself in the seat until the 45 indicator lamp goes out. In the event of a collision, the air bag control unit will not allow front passenger front air bag deployment when the OCS has classified the front passenger seat occupant as weighing as much as or less than a typical 12-month-old child in a standard child restraint or if the front passenger seat is classified as being empty.

When the OCS senses that the front passenger seat occupant is classified as being up to or less than the weight of a typical 12-month-old child in a standard child restraint, the 45 indicator lamp will illuminate when the engine is started and remain illuminated. This indicates that the front passenger front air bag is deactivated. When the OCS senses that the front passenger seat is classified as being empty, the 45 indicator lamp will illuminate when the engine is started and remain illuminated. This indicates that the front passenger front air bag is deactivated. When the OCS senses that the front passenger seat occupant is classified as being heavier than the weight of a typical 12- month-old child seated in a standard child restraint or as being a small individual (such as a young teenager or a small adult), the 45 indicator lamp will illuminate for approximately 6 seconds when the engine is started. Depending on occupant weight sensor readings from the seat, it will then remain illuminated or go out. With the 45 indicator lamp illuminated, the front passenger front air bag is deactivated.

With the 45 indicator lamp out, the front passenger front air bag is activated. When the OCS senses that the front passenger seat occupant is classified as an adult or someone larger than a small individual, the 45 indicator lamp will illuminate for approximately six seconds when the engine is started and then go out. This indicates that the front passenger front air bag is activated. If the 45 indicator lamp is illuminated, the front passenger front air bag is deactivated and will not be deployed.

Occupants, especially children, should always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the front- passenger seat: R Your vehicle is equipped with air bag technology designed to deactivate the front-passenger front air bag in your vehicle when the system senses the weight of a typical 12-month-old child or less along with the weight of a standard appropriate child restraint on the front-passenger seat. R A child in a rear-facing child restraint on the front-passenger seat will be seriously injured or even killed if the front-passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to eliminate this risk completely is never to place a child in a rear-facing child restraint in the front- passenger seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint on the rear seat.

R If you install a rear-facing child restraint on the front-passenger seat, make sure the 45 indicator lamp is illuminated, indicating that the front-passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure that the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, do not transport a child on the front-passenger seat until the system has been repaired.A child in a rear-facing child restraint on the front-passenger seat will be seriously injured or even killed if the front-passenger front air bag inflates. R If you place a child in a forward-facing child restraint on the front-passenger seat: - move the seat as far back as possible - use the proper child restraint recommended for the age, size and weight of the child - secure child restraint with the vehicle's seat belt according to the child seat manufacturer's instructions R For children larger than the typical 12- month-old child, the front-passenger front air bag may or may not be activated. Deployment of the driver front air bag does not mean that the front-passenger front air bag should also have deployed. OCS may have determined: R that the seat was unoccupied or occupied by a weight of up to or less than that of a typical 12-month-old child seated in a standard child restraint R that the seat was occupied by a small individual (e.g.

Advance microprocessor 8086 lab manual for cse. A young teenager or a small adult) or a child who weighs more than a typical 12-month-old child in a standard child restraint system These are examples of when OCS deactivates the front-passenger front air bag. The air bag is deactivated despite the impact fulfilling the criteria for deploying the driver's front air bag.Occupant safety45SafetyBA 212 USA, CA Edition B 2011; 1; 5, en-USdimargiVersion: 3.0.3.62010-05-20T13:33:46+02:00 - Seite 45Z. If the SmartKey has been removed from the ignition lock or is in position 0, indicator lamp 45: does not light up.GWarning If the red 6 SRS warning lamp in the instrument cluster and the 45 indicator lamp light up simultaneously, the OCS is malfunctioning.

The front passenger front air bag will be deactivated in this case. Have the system checked by qualified technicians as soon as possible. Contact an authorized Mercedes-Benz Center. Only have the seat repaired or replaced at an authorized Mercedes-Benz Center.

In order to ensure proper operation of the air bag system and OCS: R Sit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. R When seated, a passenger should not position him/herself in such a way as to cause the passenger's weight to be lifted from the seat cushion as this may result in the OCS being unable to correctly approximate the passenger's weight category. R Read and observe all warnings in this chapter. System self-test The 45 indicator lamp illuminates when you: R turn the SmartKey to position 1 or 2 in the ignition lock R on vehicles with KEYLESS-GO, press the Start/Stop button once or twice If an adult is seated properly on the passenger seat and the OCS classifies the occupant as an adult, the 45 indicator lamp illuminates and goes out again after approximately 6 seconds. If the seat is not occupied and the OCS classifies the front passenger seat as being unoccupied, the 45 indicator lamp will illuminate and not go out.GWarning! If the 4 5 indicator lamp does not illuminate, the system is not functioning.

You must contact an authorized Mercedes-Benz Center before seating any child on the front passenger seat. For more information, see 'Problems with the Occupant Classification System' ( Y page 47). GWarning Never place anything between seat cushion and child seat (e.g. A pillow), since it reduces the effectiveness of the OCS. The underside and rear side child restraint system must be placed entirely on the seat cushion and the backrest of the front-passenger seat backrest.

If necessary, adjust the tilt of the passenger seat backrest. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protection for the child.
