Operating safety Important safety notes G WARNING If you do not have the prescribed service/ maintenance work or any required repairs carried out, this can result in malfunctions or system failures. There is a risk of an accident. Always have the prescribed service/ maintenance work as well as any required repairs carried out at a qualified specialist workshop. G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. G WARNING Modifications to electronic components, their software as well as wiring can impair their function and/or the function of other networked components. In particular, systems relevant to safety could also be affected. As a result, these may no longer function as intended and/or jeopardize the operating safety of the vehicle. There is an increased risk of an accident and injury. Never tamper with the wiring as well as electronic components or their software. You should have all work to electrical and electronic equipment carried out at a qualified specialist workshop.
! There is a risk of damage to the vehicle if: Rthe vehicle becomes stuck, e.g. on a high
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g.
a curb or a hole in the road
Ra heavy object strikes the undercarriage
or parts of the chassis
26
Introduction
In situations like this, the body, the undercarriage, chassis parts, wheels or tires could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, no longer withstand the strain they are designed to. If the underbody paneling is damaged, combustible materials such as leaves, grass or twigs can gather between the underbody and the underbody paneling. If these materials come in contact with hot parts of the exhaust system for an extended period, they can catch fire. In such cases, have the vehicle checked and repaired immediately at a qualified specialist workshop. If on continuing your journey you notice that driving safety is impaired, pull over and stop the vehicle immediately, paying attention to road and traffic conditions. In such cases, visit a qualified specialist workshop.

Introduction
Mercedes-Benz Limited Warranty or by the New or Used-Vehicle Warranty.
Data stored in the vehicle Information about electronic data acquisition in the vehicle (Including notice pursuant to California Code § 9951) Please note that your vehicle is equipped with devices that can record vehicle systems data. If your vehicle is equipped with mbrace (Canada: TELE AID), data is transmitted in the event of an accident. This information helps, for example, to test vehicle systems after an accident and to continually improve vehicle safety. Daimler AG can access these data and submit them: Rfor safety research or vehicle diagnosis
purposes
Rwith the consent of the vehicle owner Ron the instruction of prosecuting
authorities
Rfor use in arbitration of disputes that
involve Daimler AG, its subsidiaries or its sales and service organizations
Ras otherwise required or permitted by law Please check your mbrace (Canada: TELE AID) purchase agreement to find out more about data that can be recorded and transmitted by this system. This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record data that will assist in understanding how a vehicle’s systems performed in certain crash or near crash-like situations, such as during air bag deployment or when hitting a road obstacle. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as: Rhow various systems in your vehicle are
operating
Rwhether or not the driver and passenger
seat belts are fastened
Rhow far (if at all) the driver is depressing the
accelerator and/or brake pedal and
Rhow fast the vehicle is traveling This data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, can combine the EDR data with the type of personal identification data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, who have the special equipment, can read the information if they have access to the vehicle or the EDR.

Occupant safety Important safety notes G WARNING Modifications to the restraint systems could result in them not functioning properly any more. The restraint systems could then no longer protect vehicle occupants as they are designed to do and could fail in the event of an accident or activate unexpectedly, for example. There is an increased risk of injury. Never modify parts of the restraint systems. Do not attempt to modify the wiring as well as electronic components or their software. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz center. USA only: for further information contact our Customer Assistance Center at 1-800-FOR-MERCedes (1800-367-6372).
In this section, you will learn the most important facts about the restraint system components of the vehicle. The restraint system consists of: RSeat belts RChild restraint systems RLATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by: RSRS (Supplemental Restraint System) RNECK-PRO head restraints RPRE-SAFE® RAir bag system components with:
- PASSENGER AIR BAG OFF indicator lamp - Front-passenger seat with Occupant
Classification System (OCS)
Although the systems are independent, their protective functions work in conjunction with each other. Not all air bags are deployed in an accident. i For information on infants and children traveling with you in the vehicle as well as restraint systems for infants and children,
see "Children in the vehicle" (Y page 60).
SRS (Supplemental Restraint System) Introduction RS consists of: RThe 6 RS warning lamp RAir bags RThe air bag control unit with crash sensors REmergency Tensioning Device for the front
seat belts and the outer seat belts in the rear
RSeat belt force limiters for the front seat belts and the outer seat belts in the rear
RS reduces the risk of occupants coming into contact with the vehicle's interior in the event of an accident. It can also reduce the effect of the forces to which occupants are subjected during an accident.
SRS warning lamp G WARNING If SRS is malfunctioning, child restraint system components may be triggered unintentionally or might not be triggered at all in the event of an accident with a high rate of vehicle deceleration. There is an increased risk of injury, possibly even fatal. Have SRS checked and repaired immediately at a qualified specialist workshop.
SRS functions are checked regularly when you switch on the ignition and when the engine is running. Therefore, malfunctions can be detected in good time. The6 SRS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started. The SRS components are in operational readiness when the 6 SRS indicator lamp goes out while the engine is running.
Occupant safety
41
There is a malfunction if: Rthe 6 SRS warning lamp does not light
up when the ignition is switched on
Rthe engine is running and the 6 SRS warning lamp does not go out after a few seconds
Rthe engine is running and the 6 SRS
warning lamp lights up again
Safety guidelines for seat belts, Emergency Tensioning Devices (ETDs) and air bags 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 your national 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 belt 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 not change or remove any component
or part of the SRS.
42 Occupant safety
RDo not install additional trim material, seat
covers, badges, etc. to the: - padded steering wheel boss - knee bag covers - outer side of front seat bolsters - side trim next to the rear seat backrest
front-passenger air bag cover
roof lining trim
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, Mercedes-Benz strongly recommends 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.
Air bags Important safety notes G WARNING If you modify the air bag covers or affix objects such as stickers to them, the air bags may not function correctly. There is an increased risk of injury. Never modify the air bag covers or affix objects to them. G WARNING Using unsuitable seat covers could restrict or even prevent deployment of the air bags integrated into the seats. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, the function of the air bag deactivation system could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz. G WARNING The air bag parts are hot after the airbag has been deployed. There is a risk of injury. Do not touch the air bag parts. Have the deployed air bags replaced at a qualified specialist workshop as soon as possible.
G WARNING Air bags are designed to reduce the incidence of injuries and fatalities in certain situations: Rfrontal impacts (driver's and front-
passenger front air bags and driver's knee bag)
Rside impacts (side impact air bags, window
curtain air bags and pelvis air bags)
Rrollover (window curtain air bags) However, no system available today can completely eliminate injuries and fatalities. When the air bags are deployed, a small amount of powder is released. The powder generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. In order to prevent potential breathing difficulties, you should leave the vehicle as soon as it is safe to do so. If you have any 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 In order to reduce the potential danger of injuries caused during the deployment of the front air bags, the driver and front passenger must always be correctly seated and wear their seat belts. For maximum protection in the event of a collision, you must always be in the normal seat position with your back against the backrest. Fasten your seat belt and make sure that it is correctly positioned on your body.
Occupant safety
43
As 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 fastened correctly and in a position that is as upright as possible with your back against the 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). You should be able to accomplish this by adjusting the seat and steering wheel. If 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.
Ronly hold the steering wheel on the outside. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury if the driver front air bag inflates.
Radjust the front-passenger seat as far back as possible 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 or fatal injuries 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.
Failure to follow these instructions can result in severe injuries to you or other occupants.
44 Occupant safety
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.
If the air bags are deployed, you will hear a bang, and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. The dust might cause some temporary breathing difficulty for people with asthma or other breathing trouble. To avoid this, you may wish to get out of the vehicle as soon as it is safe to do so. You can also open the window to allow fresh air to enter the vehicle interior. The6 SRS warning lamp lights up. The air bag installation locations are identified by the AIR BAG symbol. The air bags are deployed if the air bag control unit detects the need for deployment. Only in the event of such a situation will the air bags provide their supplemental protection. If the driver and front passenger do not wear their seat belts, 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, the air bags will not deploy. The driver and passenger 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 provide additional protection; they are not, however, a substitute for seat belts. All vehicle occupants must fasten their seat belts regardless of whether your vehicle is equipped with air bags 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. i After an air bag has been deployed, have the vehicle towed to the nearest qualified specialist workshop, even if your vehicle is ready to drive.
Front air bags
Driver's air bag : deploys in front of the steering wheel; front-passenger front air bag ; deploys in front of and above the glove box. The front air bags increase protection for the driver's and front passenger's head and chest. They are deployed: Rat the start of an accident with a high rate of vehicle acceleration or deceleration in a longitudinal direction
Rif the system determines that air bag
deployment can offer additional protection to that provided by the seat belt
Rindependently of other air bags in the
vehicle
The release time of the front air bags is dependent upon the use of the seat belt. If the vehicle rolls over, the front air bags are generally not deployed. Your vehicle has adaptive, two-stage front air bags. In the event of a collision, the air bag control unit evaluates the vehicle deceleration. In the first deployment stage, 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. The deployment of the front-passenger front air bag is also influenced by the weight category of the front passenger, which is determined by the Occupant Classification System (OCS) (Y page 48). The lighter the passenger-side occupant, the higher the vehicle deceleration rate required (predicted at the start of the impact) 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. The front air bags are not deployed in situations where a low impact severity is predicted. You will then be protected by the fastened seat belt. The front-passenger front air bag will only deploy if: Rthe system, based on the OCS weight sensor readings, detects that the front- passenger seat is occupied

air bags in frontal impacts if certain thresholds are exceeded. The driver's knee bag operates best in conjunction with correctly positioned and fastened seat belts. The driver's knee bag increases protection of the driver against: Rknee injuries Rthigh injuries Rlower leg injuries
Side impact air bags G WARNING Using unsuitable seat covers could restrict or even prevent deployment of the air bags integrated into the seats. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, the function of the air bag deactivation system could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz. G WARNING Sensors to control the air bags are located in the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the function of the sensors being impaired. The air bags might therefore not function properly any more. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. There is an increased risk of injury. Never modify the doors or parts of the doors. Always have work on the doors or door paneling carried out at a qualified specialist workshop.
You should only use seat covers that have been approved for your vehicle by Mercedes- Benz. The seat covers must have a special tear seam for side impact air bags. Otherwise, the side impact air bags cannot deploy

correctly and therefore cannot provide the intended protection in the event of an accident.
Side impact air bags (example: Sedan) Front side impact air bags : and rear side impact air bags ; deploy next to the outer seat cushions. 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 The side impact air bags are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate

Rindependently of the use of the seat belt Rindependently of the front air bags Rindependently of the ETDs If the vehicle rolls over, the side impact air bags are generally not deployed. Side impact air bags are deployed if the system detects high vehicle deceleration or acceleration in a lateral direction and determines that side impact air bag deployment can offer additional protection to that provided by the seat belt. Side impact air bags will not deploy in side impacts which do not exceed the system's
preset deployment thresholds for lateral acceleration/deceleration. You will then be protected by the fastened seat belt. The side impact air bag on the front- passenger side is not deployed in the following situations: ROCS has detected that the front-passenger
seat is unoccupied.
Rthe front-passenger seat belt is not
fastened.
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.
Pelvis air bags G WARNING 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 bags : enhance the level of protection of the vehicle occupants on the side of the vehicle on which the impact occurs.
The 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 the use of the seat belt Rindependently of the front air bags Rindependently of the ETDs If the vehicle rolls over, the pelvis air bags are generally not deployed.

Occupant Classification System (OCS) Method of operation G WARNING 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 the45 indicator lamp is illuminated, the front passenger front air bag is deactivated and will not be deployed.

Rthe front passenger's weight category as
identified by the OCS G WARNING According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. 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 anchorsand 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: 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 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.
RIf 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

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 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
RFor children larger than the typical 12-
month-old child, the front-passenger front air bag may or may not be activated. G WARNING 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: RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RWhen seated, a passenger should notposition 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.

50 Occupant safety
If the SmartKey is removed from the ignition lock or is in position 0, PASSENGER AIR BAG OFF indicator lamp : does not light up. The Occupant Classification System (OCS) categorizes the occupant on the front- passenger seat using a weight sensor. The front-passenger front air bag is deactivated automatically for certain weight categories. If the PASSENGER AIR BAG OFF indicator lamp is lit, the passenger air bag is disabled. The PASSENGER AIR BAG OFF indicator lamp shows you the current status. 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 fastened correctly Rin a position that is as upright as possible with their back against the seat backrest
Rwith their feet on the floor The OCS weight sensor reading is affected if the occupant's weight is transferred, e.g. by leaning on the armrest. If the front-passenger seat, the seat cover or the seat cushion are damaged, have the necessary repair work carried out at a qualified specialist workshop. For safety reasons, Mercedes-Benz recommends that you only use seat
accessories that have been approved by Mercedes-Benz. Both the driver and the front passenger should always observe the PASSENGER AIR BAG OFF indicator lamp as an indication of whether or not the front passenger is positioned correctly. Observe also the air bag display messages that can be displayed in the instrument cluster (Y page 265). If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The OCS may have detected that the seat: Ris empty or occupied by the weight of a
typical child up to twelve months old, seated in a child restraint system.
Ris occupied by a small individual, such as a
young teenager or a small adult.
Ris occupied by a child in a child restraint system whose weight is greater than that of a typical twelve month old child. These are examples of when the OCS deactivates the front-passenger front air bag. Deactivation takes place although the collision fulfills the criteria for deploying the driver's air bag. For further information, see "Air bag display messages" (Y page 265).
System self-test G WARNING If the 4 5indicator 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. G WARNING Objects between the seat surface and the child restraint system could affect the function of the OCS. This could result in the front-passenger front air bag not functioning as intended during an accident. This poses an increased risk of injury or even fatal injury.
Do not place any objects between the seat surface and the child restraint system. Make sure that the bottom and back of the child restraint system make full contact with the front-passenger seat cushion and backrest. Always comply with the child restraint system manufacturer's installation instructions.
