You can open a locked door from the inside. Open door only when conditions are safe to do so. You can deactivate the automatic locking using the control system (컄 page 153).


Simultaneously depressing the accelerator pedal and applying the brake reduces engine performance and causes premature brake and drivetrain wear.


If you hear a warning signal when driv- ing off, you have forgotten to release the parking brake. Release the parking brake.


After a cold start, the automatic transmis- sion shifts at a higher engine revolution. This allows the catalytic converter to reach its operating temperature earlier.


Warning!


On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehi- cle control. Your vehicle’s ABS will not pre- vent this type of loss of control.


Vehicles with automatic transmission: Place the gear selector lever in position P or R only when the vehicle is stopped in order to avoid damaging the transmission.


Do not run cold engine at high engine speeds. Running a cold engine at high engine speeds may shorten the service life of the engine.


Warning!


Vehicles with automatic transmission: It is dangerous to shift the gear selector le- ver out of P or N if the engine speed is high- er than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accel- erate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.

The SRS system conducts a self-test when the ignition is switched on and in regular intervals while the engine is running. This facilitates early detection of malfunctions. The 1 indicator lamp in the instrument cluster comes on when the ignition is switched on and goes out no later than a few seconds after the engine has been started. The SRS components are in operational readiness if the 1 indicator lamp is not lit when the engine is running. A malfunction in the system has been detected if the 1 indicator lamp: 앫 fails to go out after approximately four

If it is necessary to modify an air bag system to accommodate a person with disabilities, contact your local authorized Mercedes-Benz Center or call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details.


Warning!


In the event that the 1 indicator lamp comes on during driving or does not come on at all, the SRS self-check has detected a malfunction. For your safety, we strongly recommend that you visit an authorized Mercedes-Benz Center immediately to have the system checked; otherwise the SRS may not deploy when needed in an accident, which could result in serious or fatal injury, or it might deploy unexpectedly and unnec- essarily which could also result in injury.


In addition, improper work on the SRS creates a risk of rendering the SRS inopera- tive or causing unintended air bag deploy- ment. Work on the SRS must therefore only be performed by qualified technicians. Con- tact an authorized Mercedes-Benz Center.


Safety and Security Occupant safety


Air bags


Warning!


Air bags are designed to reduce the poten- tial of injury and fatality in certain frontal im- pacts (front air bags) or side impacts (side impact air bags and head protection window curtain air bags). However, no system avail- able today can totally eliminate injuries and fatalities.


The deployment of the air bags temporarily releases a small amount of dust from the air bags. This dust, however, is neither injurious to your health, nor does it indicate a fire in the vehicle. The dust might cause some tem- porary 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. 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.


59


Safety and Security Occupant safety


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 belts.


For maximum protection in the event of a collision always be in normal seated position with your back against the backrest. Fasten your seat belt and make sure that it is prop- erly positioned on your body.


Since the air bag inflates with considerable speed and force, a proper seating and hands on steering wheel position will help to keep you at a safe distance from the air bag. Occupants who are unbelted, out of position or too close to the air bag can be seriously injured by an air bag as it inflates with great force in the blink of an eye: 앫 Sit properly belted in a nearly upright


position with your back against the seat backrest.


60


앫 Adjust the driver seat as far as possible rearward, still permitting proper opera- tion of vehicle controls. The distance from the center of the driver’s breast- bone to the center of the air bag cover on the steering wheel must be at least 10 in (25 cm) or more. You should be able to accomplish this by a combina- tion of adjustments to the seat and steering wheel. If you have any prob- lems, please see an authorized Mercedes-Benz Center.


앫 Do not lean your head or chest close to


the steering wheel or dashboard.


앫 Keep hands on the outside of steering wheel rim. Placing hands and arms in- side the rim can increase the risk and potential severity of hand/arm injury when driver front air bag inflates.


앫 Adjust the front passenger seat as far as possible rearward from the dashboard when the seat is occupied.


앫 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 air bag be triggered. Always sit nearly upright, properly use the seat belts and use an appropriately sized infant or 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.


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.


Warning!


Accident research shows that the safest place for children in an automobile is in the rear seat.


It should be noted that with respect to both front and rear side impact air bags 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) 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.


(2) Always sit nearly upright, properly use the seat belts and for children 12 years old and under, use an appropriately sized infant or toddler restraint or booster seat recommended for the size and weight of the child.


(3) Always wear seat belts properly.


If you believe that, even with the use of these guidelines, it would be safer for your rear seat occupants to have the rear mounted side impact air bags deactivated, then deactivation can be accomplished upon your written request to do so at an authorized Mercedes-Benz Center at an additional cost.


Please contact your local authorized Mercedes-Benz Center or call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details.


Safety and Security Occupant safety


Air bags are designed to deploy only in certain frontal impacts (front air bags) and in side impacts (side impact and head protection window curtain air bags) which exceed preset thresholds. Only during these events will they provide their supplemental protection. The driver and passengers should always wear their seat belts. Otherwise it is not possible for air bags to provide their supplemental protection.


61


Safety and Security Occupant safety


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. We caution you not to rely on the presence of the air bags in order to avoid wearing your seat belt. It is important to your safety and that of your passengers that you replace de- ployed air bags and repair any malfunc- tioning air bags to make sure that the vehicle will continue to provide supple- mental crash protection for occupants.

Safety guidelines for the seat belt, emergency tensioning device and air bag


Warning!


앫 Damaged seat belts or belts that were highly stressed in an accident must be replaced and their anchoring points must also be checked. Only use belts installed or supplied by an authorized Mercedes-Benz Center.


앫 Air bags and emergency tensioning


devices (ETDs) are designed to function on a one-time-only basis. An air bag or ETD that is deployed must be replaced.


앫 Do not pass belts over sharp edges.


They could tear.


앫 Do not make any modification that could


change the effectiveness of the belts. 앫 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.


앫 No modifications of any kind may be made to any components or wiring of the SRS. This includes changing or removing any component or part of the SRS, the installation of additional trim material, badges, etc. over the steering wheel hub, passenger front air bag cover, door trim panels, or door frame trims, and installation of additional electrical/electronic equipment on or near SRS components and wiring. Keep area between air bags and occupants free from objects (e.g. packages, purses, umbrellas, etc.).


앫 Do not hang items such as coat hangers from the coat hooks or handles over the door. These items may turn into projec- tiles and cause head and other injuries when curtain air bag is deployed.


앫 Never place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.


앫 Air bag system components will be hot


after an air bag has inflated. Do not touch.


앫 In addition, improper 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.


앫 For your protection and the protection of others, when scrapping the air bag unit or emergency tensioning device, our safety instructions must be fol- lowed. These instructions are available from your authorized Mercedes-Benz Center.


앫 Given the considerable deployment


speed, required inflation volume, and the textile structure of the air bags, there is the possibility of abrasions or other more significant injuries resulting from air bag deployment.


When you sell your vehicle we strongly urge you to give notice to the subsequent owner that it is equipped with an SRS by alerting them to the applicable section in the Operator’s Manual.

Safety and Security Occupant safety


The front air bags in this vehicle have been designed to inflate in two stages. This allows the air bag to have different rates of inflation that are based on the rate of relevant vehicle deceleration as assessed by the air bag control unit. On the front passenger side, the front air bag deployment is additionally influenced by the passenger’s weight category as identified by the Occupant Classification System (OCS) (컄 page 71). The lighter the front passenger side occupant, the higher the vehicle deceleration rate required for the second stage inflation of the air bag.


63


Safety and Security Occupant safety


The air bags will not deploy in impacts which do not exceed the system’s deployment thresholds. You will then be protected by the fastened seat belts. The passenger front air bag will only be deployed if: 앫 the system, based on OCS weight

Seat belts


When the engine is started, the seat belt telltale < illuminates to remind you and your passengers to fasten your seat belts. If the driver’s seat belt is not fastened before the engine is started, the seat belt telltale < illuminates and a warning chime sounds for approximately six seconds when the engine is started. 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 more information, see “Fastening the seat belt” (컄 page 43).


i For information on infants and children traveling with you in the vehicle and restraint systems for infants and children, see “Children in the vehicle” (컄 page 68).


Safety and Security Occupant safety


Warning!


Warning!


Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained, even those sitting in the rear and pregnant women.


Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. You and your passengers should always wear seat belts.


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. Air bags can only protect as they are designed if the occupants are properly wearing their seat belts.


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 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 nearly upright position and the belt is properly positioned on the body.


Warning!


Never let more people ride in the vehicle than there are seat belts available. Be 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.


65


Safety and Security Occupant safety


Warning!


Warning!


Damaged seat belts or belts that were highly stressed in an accident must be replaced and their anchoring points must also 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 failure.


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.


USE SEAT BELTS PROPERLY 앫 Seat belts can only work when used


properly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in case of an accident.


앫 Each occupant should wear their seat


belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, includ- ing rollovers. The integrated restraint system includes SRS (driver air bag, passenger front air bag, side impact air bags, head protection window curtain air bags for side windows), ETD (seat belt emergency tensioning device), 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 ETD) and side (side impact and window curtain air bags and ETD) impacts which exceed preset deployment thresholds.


앫 Never wear the shoulder belt under your arm, against your neck or off your shoul- der. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. The belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen.


66


앫 Never wear belts over rigid or breakable objects in or on your clothing, such as eyeglasses, pens, keys, etc., as these might cause injuries.


앫 Position the lap belt as low as possible on your hips and not across the abdo- men. If the belt is positioned across your abdomen, it could cause serious injuries in a crash.


앫 Never use a seat belt for more than one person at a time. Do not fasten a seat belt around a person and another person or other objects.


앫 Belts should not be worn twisted. In a crash, you wouldn’t have the full width of the belt to distribute impact forces. The twisted belt against your body could cause injuries.


앫 Pregnant women should also use a


lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen.


앫 Never place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.


앫 When using a seat belt to secure infant


or toddler restraints or children in booster seats, always follow the child seat manufacturer’s instructions.


Safety and Security Occupant safety


Emergency tensioning device (ETD), seat belt force limiter The seat belts for the front and rear outer seats are equipped with emergency tensioning devices and belt force limiters. The ETD is designed to activate in the following cases: 앫 in frontal or rear-end impacts


exceeding a preset severity level.


앫 if the restraint systems are operational


and functioning correctly, see 1 indicator lamp (컄 page 58).


The ETDs for the front seats will only activate if the front seat belts are fastened (latch plate properly inserted into buckle). The ETDs for the rear outer seats will activate with or without the respective seat belts fastened.


67


Safety and Security Occupant safety


In an impact, emergency tensioning devices remove slack from the belts. Belt force limiters reduce the force exerted by the seat belts on occupants during a crash.


Warning!


An emergency tensioning device (ETD) that was activated must be replaced.


When disposing of the emergency tension- ing device, our safety instructions must be followed. These are available at your authorized Mercedes-Benz Center.


Children in the vehicle


If an infant or child is traveling with you in the vehicle: 앫 Secure the child using an infant or child


restraint appropriate to the age and size of the child.


앫 Make sure that the infant or child is


properly secured at all times while the vehicle is in motion.


Infant and child restraint seats and information on choosing an appropriate restraint system can be obtained from any Mercedes-Benz Center.


Infant and child restraint systems We recommend all infants and children be properly restrained at all times while the vehicle is in motion. All lap-shoulder belts except the driver‘s seat belt have special seat belt retractors for secure fastening of child restraints. To fasten a child restraint, follow child restraint instructions for mounting. Then pull the shoulder belt out completely and let it retract. During seat belt retraction, a ratcheting sound can be heard to indicate that the special seat belt retractor is activated. The belt is now locked. Push down on child restraint to take up any slack. To deactivate, release seat belt buckle and let seat belt retract completely. The seat belt can again be used in the usual manner.

The use of infant or child restraints is required by law in all 50 states, the District of Columbia, the U.S. territo- ries and all Canadian provinces. Infants and small children should be seated in an appropriate infant or child restraint system, properly secured by a lap/shoulder belt or, if so equipped, a top tether anchorage point and a child restraint lower anchorage system that complies with U.S. Federal Motor Vehi- cle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2.


Warning!


Warning!


Never release the seat belt buckle while the vehicle is in motion, since the special seat belt retractor will be deactivated.


A statement by the child restraint man- ufacturer of compliance with this stan- dard can be found on the instruction label on the restraint and in the instruc- tion manual provided with the restraint. When using any infant, or toddler re- straint, or booster seat, be sure to care- fully read and follow all manufacturer’s instructions for installation and use. Please read and observe warning labels affixed to the inside of the vehicle and to infant or child restraints.


According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat- ing 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 or child restraint recom- mended 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 instruc- tions.

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: 앫 Your vehicle is equipped with air bag


technology designed to turn off the front passenger front air bag in your vehicle when the OCS 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.


앫 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 completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat.

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 air bag may or may not be activated (컄 page 73).


앫 If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure that the 56 indicator lamp is illuminated, indicating that the front passenger air bag is deactivated. Should the 56 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 56 indicator lamp while driving to make sure the 56 indicator lamp is illuminated. If the 56 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.


When the child restraint is not in use, remove it from the vehicle or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident.


Do not leave children unattended in the vehicle, even if the children are secured in a child restraint system. Unsupervised children in a child restraint system may use vehicle equipment and may cause an accident and/or serious personal injury.


Warning!


Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt.


A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/or the child is not properly secured in the child restraint.


Children too big for a toddler restraint must ride in seats using regular seat belts. Posi- tion shoulder belt across chest and shoul- der, not face or neck. A booster seat may be necessary to achieve proper belt positioning for children from 41 lbs until they reach a height where a lap/shoulder belt fits properly without a booster.


Safety and Security Occupant safety


Occupant Classification System The Occupant Classification System (OCS) automatically turns the front passenger front air bag on or off based on the classi- fied occupant weight category determined by weight sensor readings from the front passenger seat.


The system does not deactivate the front passenger side impact air bag, the window curtain air bag and the emergency tensioning device.


Occupants must sit properly belted in a nearly upright position with their back against the seat backrest and feet on the floor to be correctly classified. 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.

If your seat, including your trim cover and cushion needs to be serviced in any way, take the vehicle to your authorized Mercedes-Benz Center. Only seat accessories approved by Mercedes-Benz may be used.


Both driver and the front passenger should always use the 56 indicator lamp as an indication of whether or not the front passenger is properly positioned.


72


Warning!


If the 56 indicator lamp illuminates when an adult or someone larger than a small individual is in the front passenger seat, have the front passenger re-position himself or herself in the seat until the 56 indicator lamp goes out.


More information about air bag display messages (컄 page 354). In the event of a collision, the air bag control unit will not allow front passenger front air bag deployment when the OCS classified the front passenger seat occupant as being up to or less than the weight of a typical 12-month-old child in a standard child restraint or if the front passenger seat is sensed as being empty.


When the OCS senses that the front passen- ger 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 56 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 passen- ger seat is classified as being empty, the 56 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 passen- ger 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 56 indicator lamp will illuminate for approximately six seconds when the engine is started and then, depending on occupant weight sensor readings from the seat, remain illuminated or go out. With the 56 indicator lamp illuminated, the front passenger front air bag is deactivated. With the 56 indicator lamp out, the front passenger front air bag is activated.


When the OCS senses that the front passen- ger seat occupant is classified as an adult or someone larger than a small individual, the 56 indicator lamp will illuminate for approximately six seconds when the engine is started and then go out, indicating that the front passenger front air bag is activated.


If the 56 indicator lamp is illuminated, the front passenger front air bag is deactivated and will not be deployed. If the 56 indicator lamp is not illuminated, the front passenger front air bag is activated and will be deployed: 앫 in the event of certain frontal impacts 앫 if impact exceeds a preset deployment


threshold


앫 independently of the side impact air


bags.


If the front passenger front air bag is deployed, the rate of inflation will be influenced by: 앫 the rate of relevant vehicle deceleration as assessed by the air bag control unit 앫 front passenger’s weight category as


identified by the Occupant Classification System (OCS).


Safety and Security Occupant safety


Warning!


According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat- ing 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 or child restraint recom- mended 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 instruc- tions.

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: 앫 Your vehicle is equipped with air bag


technology designed to turn off 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 appropri- ate child restraint on the front passen- ger seat.


앫 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 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 the back seat.


74


앫 If 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 (컄 page 73).


앫 If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure that the 56 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 56 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 56 indicator lamp while driving to make sure the 56 indicator lamp is illuminated. If the 56 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 passenger front air bag inflates.


앫 that the seat was occupied by a small individual (such as a young teenager or a small adult) or a child weighing more than the weight of a typical 12-month-old child in a standard child restraint - 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.


Deployment of the driver front air bag does not mean that the front passenger front air bag also should have deployed. The Occupant Classification System (컄 page 71) may have determined: 앫 that 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 instances where the system suppresses deployment of the front passenger front air bag even though the impact met the cri- teria and was of sufficient severity to deploy the driver front air bag.

Warning!


If the 1 indicator lamp and the 56 indicator lamp are lit at the same time, there is a malfunction in the Occupant Classification System. The front passenger front air bag will be deactivated in this case.


In order to ensure proper operation of the air bag system and OCS: 앫 Have the system checked as soon as


possible by qualified technicians. Contact an authorized Mercedes-Benz Center.


앫 Sit properly belted in a nearly upright


position with your back against the seat backrest.


앫 Do not lean on the armrests or lift your- self from the seat by using the handle over the door as this may cause the OCS to be unable to correctly approximate the occupant weight category.


앫 Only have the seat repaired or replaced


by an authorized Mercedes-Benz Center.


앫 Read and observe all warnings in this


chapter.


Self-test Occupant Classification System After turning the SmartKey in the starter switch to position 1 or 2, the 56 indicator lamp located in the center console illuminates. If an adult occupant is properly sitting on the front passenger seat and the system senses the occupant as being an adult, the 56 indicator lamp will illuminate and go out after approximately six seconds. If the seat is not occupied and the system senses the front passenger seat as being empty, the 56 indicator lamp will illuminate and not go out.


Warning!


If the 56 indicator lamp should not illuminate, 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 (컄 page 350).


Warning!


Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the Occupant Classifi- cation System. The bottom of the child seat must make full contact with the passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protec- tion for the child.


Follow the manufacturer’s instructions for installation of child seats.

왔 Driving safety systems In this section you will find information on the following driving safety systems: 앫 ABS (Antilock Brake System) 앫 BAS (Brake Assist System) 앫 ESP (Electronic Stability Program) 앫 4MATIC (Four Wheel Electronic


Traction System)


In winter operation, the maximum effectiveness of the ABS, ESP, and 4MATIC (if so equipped) is only achieved with winter tires (M+S tires), or snow chains as required.


Safety and Security Driving safety systems


Warning!


ABS


The following factors increase the risk of accidents: 앫 Excessive speed, especially in turns 앫 Wet and slippery road surfaces 앫 Following another vehicle too closely The ABS, BAS, ESP, and 4MATIC (if so equipped) cannot reduce this risk.


Always adjust your driving style to the prevailing road and weather conditions.


Warning!


Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pump- ing the brake pedal defeats the purpose of the ABS and significantly reduces braking effectiveness.


The Antilock Brake System (ABS) regulates the brake pressure so that the wheels do not lock during braking. This allows you to maintain the ability to steer your vehicle. The ABS is functional above a speed of ap- proximately 5 mph (8 km/h) independent of road surface conditions. On slippery road surfaces, the ABS will respond even to light brake pressure. The - indicator lamp in the instrument cluster (컄 page 24) comes on when you switch on the ignition. It goes out when the engine is running.


83


Safety and Security Driving safety systems


Braking At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal, indicating that the ABS is in the regulating mode. 왘 Keep firm and steady pressure on the


brake pedal while experiencing the pulsation.


Continuous steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and ability to steer the vehicle. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.


84


Emergency brake maneuver 왘 Keep continuous full pressure on the


brake pedal.


Warning!


The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction af- forded. The ABS cannot prevent accidents, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning. Only a safe, atten- tive, and skillful driver can prevent acci- dents. The capabilities of an ABS equipped vehicle must never be exploited in a reck- less or dangerous manner which could jeop- ardize the user’s safety or the safety of others.


For more information, see “Practical hints” (컄 page 344) and (컄 page 358).


BAS


The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, thereby poten- tially reducing the braking distance. Apply continuous full braking pressure until the emergency braking situation is over. The ABS will prevent the wheels from locking. When you release the brake pedal, the brakes function again as normal. The BAS is then deactivated.


Warning!


If the BAS is malfunctioning, the brake sys- tem is still functioning normally, but without the additional brake boost available that BAS would normally provide in an emergen- cy braking maneuver. Therefore, the braking distance may increase.


Warning!


ESP


The BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. The BAS cannot prevent accidents, includ- ing those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a BAS equipped vehicle must never be exploited in a reckless or danger- ous manner which could jeopardize the user’s safety or the safety of others.


For more information, see “Practical hints” (컄 page 359).


The Electronic Stability Program (ESP) is operational as soon as the engine is run- ning and monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling. The ESP recognizes when a wheel is spinning or if the vehicle starts to skid. By applying brakes to the appropriate wheel and by limiting the engine output, the ESP works to stabilize the vehicle. The ESP is especially useful while driving off and on wet or slippery road surfaces. The ESP also stabilizes the vehicle during braking maneuvers. The ESP warning lamp v in the speedometer flashes when the ESP is engaged. The ESP warning lamp v in the speedometer comes on when you switch on the ignition. It goes out when the engine is running.


Safety and Security Driving safety systems


Warning!


Never switch off the ESP when you see the ESP warning lamp v flashing in the speedometer. In this case, proceed as follows: 앫 While driving off, apply as little throttle


as possible.


앫 While driving, ease up on the accelera-


tor.


앫 Adapt your speed and driving style to


the prevailing road conditions.


Failure to observe these guidelines could cause the vehicle to skid.


The ESP cannot prevent accidents resulting from excessive speed.


85


Safety and Security Driving safety systems


Warning!


The ESP cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded. The ESP cannot prevent accidents, including those resulting from excessive speed in turns or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP equipped vehicle must never be exploited in a reckless or danger- ous manner which could jeopardize the user’s safety or the safety of others.


The ESP will only function properly if you use wheels of the recommended tire size (컄 page 424).


86


Vehicles without 4MATIC: Because of the ESP’s automatic operation, the engine must be shut off (SmartKey in starter switch position 0 or 1) when 앫 the parking brake is being tested on


a brake test dynamometer


앫 the vehicle is being towed with the


front axle raised


Active braking action through the ESP may otherwise seriously damage the brake system. For information on vehicles with 4MATIC, see “Four wheel electronic traction system (4MATIC) with the ESP” (컄 page 88).


For more information, see “Practical hints” (컄 page 348) and (컄 page 360).


Switching off the ESP


Warning!


The ESP should not be switched off during normal driving other than in the circum- stances described below. Disabling of the system will reduce vehicle stability in stan- dard driving maneuvers.


To improve the vehicle’s traction, turn off the ESP in driving situations where it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: 앫 starting out on slippery surfaces and in
