breathing difficulty but cannot get out of the vehicle after the air bag inflates, then get fresh air by opening a window or door. G Warning! To reduce the risk of injury when the front air bags inflate, it is very important for the driver and front passenger to always be in a properly seated position and to wear their respective seat belt. For maximum protection in the event of a collision always be in normal seated position with your back against the seat backrest. Fasten your seat belt and make sure it is properly positioned on your body. Since the air bag inflates with considerable speed and force, a proper seating position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag as it inflates with great force instantaneously: RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RMove the driver’s seat as far back as possible, still permitting proper operation of vehicle controls. The distance from the center of the driver’s chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm) or more. You should be able to accomplish this by adjusting the seat and steering wheel. If 164_AKB; 7; 31, en-US d2ureepe, 38 Occupant safety 2009-09-11T12:07:36+02:00 - Seite 38 Version: 2.11.8.1 you have any difficulties, please contact an authorized Mercedes-Benz Center. RDo not lean your head or chest close to the steering wheel or dashboard. RKeep hands on the outside of the steering wheel 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. RAdjust the front passenger seat as far as possible rearward from the dashboard when the seat is occupied. ROccupants, 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 infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. RCanada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ air bag deactivation system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result. 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. G Warning! Accident research shows that the safest place for children in an automobile is in a rear seat. There is a possibility for a side impact air bag- related injury 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) (2) Always sit as upright as possible, wear the seat belt properly, and for children 12 years old and under, use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Always wear seat belts properly. Air bags are designed to deploy only in certain Rfrontal impacts (front air bags) Rside impacts (side impact and window curtain air bags) if the system determines the need for air bag deployment Rrollovers (window curtain air bags) Only in the event of such a situation will they provide their supplemental protection. The driver and passengers should always wear their seat belts. Otherwise it is not possible for the air bags to provide their supplemental protection. In case 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 are not a substitute for seat belts. Always wear your seat belt, regardless of whether or not your vehicle is equipped with air bags. It is important to your safety and that of your passengers to have deployed air bags replaced and to have any malfunctioning air 164_AKB; 7; 31, en-US d2ureepe, 2009-09-11T12:07:36+02:00 - Seite 39 Version: 2.11.8.1 bags repaired. This will help to make sure the air bags will continue to provide supplemental crash protection for occupants. Safety guidelines for the seat belt, Emergency Tensioning Device (ETD) and air bag G Warning! RDamaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Their anchoring points must also be checked. Only use seat belts installed or supplied by an authorized Mercedes-Benz Center. RAir bags and pyrotechnic Emergency Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and regard for the environment. Check with your local government’s disposal guidelines. California residents, see www.dtsc.ca.gov/HazardousWaste/ Perchlorate/index.cfm. RAir bags and ETDs are designed to function on a one-time-only basis. An air bag or ETD that has deployed must be replaced. PRE- SAFE® has electrically operated reversible pre-tensioners in addition to the pyrotechnic ETDs. RDo not pass seat belts over sharp edges. They could tear. RDo not make any modification that could change the effectiveness of the seat belts. RDo not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. RNo modifications of any kind may be made to any components or wiring of the SRS. RDo no change or remove any component or part of the SRS. RDo not install additional trim material, seat covers, badges, etc. over the steering wheel hub, front passenger front air bag Occupant safety 39 cover, outboard sides of the seat backrests, door trim panels, or door frame trims. RDo not install additional electrical/ electronic equipment on or near SRS components and wiring. RKeep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.). RDo not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed. RAir bag system components will be hot after an air bag has inflated. Do not touch them. RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat. RImproper repair work on the SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. RFor your protection and the protection of others, when scrapping the air bag unit or ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz Center. RGiven the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment. If you sell your vehicle, we strongly recommend that you inform the subsequent owner that the vehicle is equipped with SRS. Also refer them to the applicable section in the Operator’s Manual. 164_AKB; 7; 31, en-US d2ureepe, 40 Occupant safety Front air bags G Observe Safety notes, see page 37. Driver’s front air bag : and front passenger front air bag ; are designed to provide increased protection for the driver and front passenger against the risk of injuries to the head and thorax. Driver and front passenger front air bags 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 Rdepending on whether the respective seat belt is in use Rindependently of the side impact air bags and/or the window curtain air bags The front air bags in this vehicle have been designed to inflate in two stages. This allows the air bags to have different rates of inflation. The rate of inflation is based on the vehicle deceleration rate as assessed by the air bag control unit. Vehicles with OCS, USA only: The front passenger front air bag deployment is additionally influenced by the passenger’s weight category as identified by the Occupant Classification System (OCS) (Y page 42). Vehicles with OCS, USA only: The lighter the front passenger-side occupant, the higher the vehicle deceleration rate required for second stage inflation of the front passenger front air bag. 2009-09-11T12:07:36+02:00 - Seite 40 Version: 2.11.8.1 The air bags will not deploy in impacts which do not exceed the system’s preset deployment thresholds. You will then be protected by the fastened seat belts. The front air bags will not deploy in the event of a rollover unless the vehicle’s rate of longitudinal deceleration or acceleration exceeds the preset deployment threshold for the front air bags. The front passenger front air bag will only be deployed if Rvehicles with OCS, USA only: the system, based on OCS weight sensor readings, detects that the front passenger seat is occupied Rthe 42 indicator lamp in the center console is not lit (USA only: (Y page 42), Canada only: (Y page 46)) Rthe impact exceeds a preset deployment threshold ! Vehicles with BabySmart™ air bag deactivation system (Canada only): Do not place objects heavier than 20 lb (9 kg) on the front passenger seat. This could cause the front or side impact air bag on the front passenger side to deploy in a crash which exceeds the system’s deployment threshold. Side impact air bags G Observe Safety notes, see page 37. G Warning! 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 164_AKB; 7; 31, en-US d2ureepe, 2009-09-11T12:07:36+02:00 - Seite 41 Version: 2.11.8.1 doors must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. Front side impact air bags : and rear side impact air bags ; are designed to provide increased protection for the thorax but not the head, neck and arms. The side impact air bags are deployed Ron the impacted side of the vehicle Rin instances with a high rate of lateral vehicle deceleration or acceleration Rregardless of whether the seat belts on the impacted side of the vehicle are in use Rindependently of the front air bags Rindependently of the ETDs Vehicles with OCS (USA only): The front passenger side impact air bag will not deploy if the OCS senses that the front passenger seat is empty and the front passenger seat belt is not fastened. With the front passenger seat empty and the seat belt fastened, the front passenger side impact air bag will deploy independently of the empty seat. Whether a seat belt is recognized as fastened depends on whether or not the latch plate is properly inserted into the buckle. The side impact air bags are not deployed in side impacts which do not exceed the system’s deployment threshold. The side impact air bags will not deploy in the event of a rollover unless the vehicle’s rate of lateral deceleration or acceleration exceeds Occupant safety 41 the preset deployment threshold for the side impact air bags. ! Vehicles with BabySmart™ air bag deactivation system (Canada only): Do not place objects heavier than 20 lb (9 kg) on the front passenger seat. This could cause the front or side impact air bag on the front passenger side to deploy in a crash which exceeds the system’s deployment threshold. G Warning! Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat covers may interfere with or prevent the deployment of the side impact air bags. Contact an authorized Mercedes-Benz Center for availability. Window curtain air bags G Observe Safety notes, see page 37. Window curtain air bags : are designed to provide increased protection for the head but not the chest or arms. Window curtain air bags : are deployed Ron the impacted side of the vehicle Rin instances with a high rate of lateral vehicle deceleration or acceleration Rindependently of the front air bags 164_AKB; 7; 31, en-US d2ureepe, 42 Occupant safety Rregardless of whether the front passenger seat is occupied Rin certain vehicle rollovers, if the system determines that air bag deployment can offer additional protection to that provided by the seat belt Window curtain air bags : are not deployed in impacts which do not exceed the system’s deployment threshold. Window curtain air bags : deploy in the area indicated by the arrows. Occupant Classification System The Occupant Classification System (OCS) is standard equipment in USA. The OCS activates or deactivates the front passenger front air bag automatically. The respective status is based on the classified occupant weight category determined by weight sensor readings from the front passenger seat. The system does not deactivate Rthe front passenger side impact air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices (ETDs) 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 the feet on the floor If the occupant’s weight is transferred to another object in the vehicle (e.g. by leaning on armrests), the OCS may not be able to properly approximate the occupant’s weight category. 2009-09-11T12:07:36+02:00 - Seite 42 Version: 2.11.8.1 Furthermore, the occupant weight may appear to increase or decrease due to the following: Robjects hanging on the seat Robjects lodged underneath the seat Robjects stuffed between the seat and middle console Robjects stuffed between the seat and door Rother passengers pushing on the seat Robjects applying pressure to the back of the seat Always make sure the seat has clearance in all directions at all times. If your seat, including the trim cover and cushion, needs to be serviced in any way, take the vehicle to an authorized Mercedes-Benz Center. Only seat accessories approved by Mercedes-Benz may be used. Both the driver and the front passenger should always use the 42 indicator lamp as an indication of whether or not the front passenger is properly positioned. G Warning! If the 42 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 42 indicator lamp goes out, or check whether objects are caught under or around the seat. 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 weighting 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. 164_AKB; 7; 31, en-US d2ureepe, 2009-09-11T12:07:36+02:00 - Seite 43 Version: 2.11.8.1 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 42 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the front passenger front air bag is deactivated. When the OCS senses that the front passenger seat is classified as being empty, the 42 indicator lamp will illuminate when the engine is started and remain illuminated, indicating 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 42 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then, depending on occupant weight sensor readings from the seat, remain illuminated or go out. With the 42 indicator lamp illuminated, the front passenger front air bag is deactivated. With the 42 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 42 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then goes out, indicating that the front passenger front air bag is activated. If the 42 indicator lamp is illuminated, the front passenger front air bag is deactivated and will not be deployed. Occupant safety 43 If the 42 indicator lamp is not illuminated, the front passenger front air bag is activated and will be deployed Rin the event of certain frontal impacts Rif impact exceeds a preset deployment threshold Rindependently of the side impact air bags If the front passenger front air bag is deployed, the rate of inflation will be influenced by Rthe rate of relevant vehicle deceleration as assessed by the air bag control unit Rthe front passenger’s weight category as identified by the OCS For more information on air bag display messages in the multifunction display, see (Y page 275). G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions. 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. 164_AKB; 7; 31, en-US d2ureepe, 44 Occupant safety 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: RYour 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. RA 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 completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in a backseat. RIf you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 42 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 42 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 42 indicator lamp while driving to make sure the 42 indicator lamp is illuminated. If the 42 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 2009-09-11T12:07:36+02:00 - Seite 44 Version: 2.11.8.1 injured or even killed if the front passenger front air bag inflates. RIf you have to 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, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions. 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 also should have deployed. The OCS may have determined Rthat the seat was empty or occupied by the weight up to or less than that of a typical 12-month-old child seated in a standard child restraint – both of which are instances where the system suppresses deployment of the front passenger front air bag even though the impact met the criteria and was of sufficient severity to deploy the driver front air bag Rthat the seat was occupied by a small individual (such as a young teenager or a small adult) or a child who weighs more than the weight of a typical 12-month-old child in a standard child restraint – both of which are instances where the system may suppress deployment of the front passenger front air bag even though the impact met the criteria and was of sufficient severity to deploy the driver front air bag 164_AKB; 7; 31, en-US d2ureepe, 2009-09-11T12:07:36+02:00 - Seite 45 Version: 2.11.8.1 Occupant safety 45 RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RWhile seated, an occupant should not position him/herself in such a way as to cause the occupant’s weight to be lifted from the seat bottom as this may result in the OCS being unable to correctly approximate the occupant’s weight category. RRead and observe all warnings in this chapter. OCS Self-test After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO start/stop button once or twice, the 42 indicator lamp illuminates. If an adult occupant is properly sitting on the front passenger seat and the system classifies the occupant as an adult, the 42 indicator lamp will illuminate and go out after approximately 6 seconds. If the seat is not occupied and the system classifies the front passenger seat as being empty, the 42 indicator lamp will illuminate and not go out. G Warning! If the 42 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 the “Practical hints” section (Y page 305). G Warning! Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the OCS. The bottom and back of the child seat must make full contact with the passenger seat cushion and backrest. 42 indicator lamp : will be illuminated, except with the SmartKey removed from the starter switch or with the starter switch in position 0. G Warning! If the red SRS indicator lamp + in the instrument cluster and the 42 indicator lamp are lit at the same time, there is a malfunction in the OCS. 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: RDo not place more than 4.4 lb (2 kg) into the parcel net on the back of the front passenger seat. Otherwise, the OCS may not be able to properly approximate the occupant weight category. RDo not place objects under and/or around the front passenger seat. RDo not hang anything from or attach any items to the seats. RDo not stuff objects such as books between the front passenger seat and the center console or front passenger door. RDo not move the front passenger seat backwards against stiff objects. 164_AKB; 7; 31, en-US d2ureepe, 46 Occupant safety 2009-09-11T12:07:36+02:00 - Seite 46 Version: 2.11.8.1 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. Follow the manufacturer’s instructions for installation of child seats. BabySmart™ air bag deactivation system The BabySmart™ air bag deactivation system is standard equipment in Canada. G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions. 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: RChildren 12 years old and under must never ride in the front seat, except in a Mercedes- Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result. RA 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 completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in a backseat. RIf you must install a BabySmart™ compatible rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 42 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 42 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 42 indicator lamp while driving to make sure the 42 indicator lamp is illuminated. If the 42 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. RIf you have to 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 164_AKB; 7; 31, en-US d2ureepe, 2009-09-11T12:07:36+02:00 - Seite 47 Version: 2.11.8.1 of the child, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions. G Warning! When using a BabySmart™ compatible child seat on the front passenger seat, the front passenger front air bag will not deploy only if the 42 indicator lamp remains illuminated. Please be sure to check the 42 indicator lamp every time you use a BabySmart™ compatible child seat on the front passenger seat. Should the 42 indicator lamp go out while the restraint is installed, please check installation. If the 42 indicator lamp remains out, do not use the BabySmart™ restraint to transport a child on the front passenger seat until the system has been repaired. Special BabySmart™ compatible child seats, designed for use with the Mercedes-Benz system, are required for use with the BabySmart™ air bag deactivation system. Please contact an authorized Mercedes-Benz Center for information on availability. With the special child seat installed properly, the front passenger front air bag will not deploy. The 42 indicator lamp : will be illuminated, except with the SmartKey removed from the starter switch or with the starter switch in position 0.

If the 42 indicator lamp should not come on or is continuously lit, the system is not functioning. You must see an authorized Mercedes-Benz Center before seating any child on the front passenger seat. More information can be found in the “Practical hints” section (Y page 305). G Warning! Do not place powered-on laptops, mobile phones, electronic tags such as those used in ski passes and like electronic devices on the front passenger seat. Signals from such devices may interfere with the BabySmart™ air bag deactivation system. Such signal interference may cause the 42 indicator lamp not to come on during self-test. The SRS indicator lamp + and/or the 42 indicator lamp could be continuously lit, indicating that the system is not functioning. The front passenger front air bag could deploy inadvertently or fail to deploy in an accident. G Warning! The BabySmart™ air bag deactivation system will ONLY work with a special child seat designed to operate with it. It will not work with child seats which are not BabySmart™ compatible. Never place anything between seat cushion and child seat (e.g. pillow), since it reduces 164_AKB; 7; 31, en-US d2ureepe, 48 Occupant safety 2009-09-11T12:07:36+02:00 - Seite 48 Version: 2.11.8.1 the effectiveness off the BabySmart™ air bag deactivation system. The bottom of the child seat must make full contact with the front passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of protecting the child. Follow the manufacturer’s instructions for installation of special child seats. Seat belts Safety notes The use of seat belts and infant and child restraint systems is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces. Even where this is not the case, all vehicle occupants should have their seat belts fastened whenever the vehicle is in motion. For information on infants and children traveling with you in the vehicle and restraint systems for infants and children, see “Children in the vehicle” (Y page 55). G Warning! Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts. Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts. G Warning! Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body. G Warning! Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time. G Warning! Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Also, the seat belt anchoring points must be checked. Only use seat belts which have been approved by Mercedes-Benz. Do not make any modifications to the seat belts. This can lead to unintended activation of the ETDs or to their failure to activate when necessary. Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center. Proper use of seat belts G Warning! USE SEAT BELTS PROPERLY RSeat belts can only protect when used properly. Never wear seat belts in any other 164_AKB; 7; 31, en-US d2ureepe, 2009-09-11T12:07:36+02:00 - Seite 49 Version: 2.11.8.1 way than as described in this section, as that could result in serious injuries in case of an accident. REach occupant should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, including rollovers. The integrated restraint system includes SRS (driver front air bag, front passenger front air bag, side impact air bags, window curtain air bags for door windows), Emergency Tensioning Devices (ETDs), seat belt force limiters, and front seat knee bolsters. The system is designed to enhance the protection offered to properly belted occupants in certain frontal (front air bags and ETDs) and side (side impact air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds and in certain rollovers (window curtain air bags and ETDs). RNever wear the shoulder belt under your arm, against your neck or off your shoulder. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries.
