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 instructions.

Safety and Security Occupant safety

Children can be killed or seriously injured by an inflating air bag. Note the following im- portant information when circumstances re- quire 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. 컄컄

컄컄

앫 If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 5/ indica- tor lamp is illuminated, indicating that the front passenger front air bag is deac- tivated. Should the 5/ indicator lamp not illuminate or go out while the restraint is installed, please check in- stallation. Periodically check the 5/ indicator lamp while driving to make sure the 5/ indicator lamp is illuminated. If the 5/ 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.

44

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.

i 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 41) 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 im- pact met the criteria and was of sufficient severity to deploy the driver front air bag.

앫 that the seat was occupied by a small individ-

ual (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 suffi- cient severity to deploy the driver front air bag.

Have the system checked as soon as possi- ble by qualified technicians. Contact an au- thorized 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: 앫 Sit properly belted in a position that is as upright as possible with your back against the seat backrest.

앫 While 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 ap- proximate the occupant’s weight category.

Safety and Security Occupant safety

Self-test Occupant Classification System After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO* start/stop button (Canada only) once or twice, the 5/ indicator lamp 1 illuminates. If an adult occupant is properly sitting on the front passenger seat and the system senses the occupant as being an adult, the 5/ indicator lamp will illuminate and go out after ap- proximately 6 seconds. If the seat is not occupied and the system senses the front passenger seat as being empty, the 5/ indicator lamp will illuminate and not go out.

If the 5/indicator lamp should not il- luminate, the system is not functioning. You must see an authorized Mercedes-Benz Center before seating any child on the front passenger seat.

The 5/ indicator lamp 1 will be illuminated, except with the SmartKey removed from the starter switch or with the starter switch in position 0.

Warning!

If the = indicator lamp and the 5/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.

Safety and Security Occupant safety

For more information, see the “Practical hints” section (컄 page 385).

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.

Seat belts

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 fas- tened whenever the vehicle is in motion. For more information, see “Fastening the seat belts” (컄 page 105).

i For information on infants and children trav- eling with you in the vehicle and restraint sys- tems for infants and children, see “Children in the vehicle” (컄 page 51).

Warning!

Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained.

Failure to wear and properly fasten and po- sition 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 ve- hicle or be ejected from it. You can be seri- ously 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 for, if the occupants are properly wearing their seat belts.

Safety and Security Occupant safety

Warning!

Warning!

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 se- rious or even fatal injuries. The seat back- rest and seat belt provide the best restraint when the wearer is in a nearly upright posi- tion and the seat belt is properly positioned on the body.

Warning!

Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is cor- rectly restrained with a separate seat belt. Never use a seat belt for more than one per- son at a time.

Damaged seat belts or seat belts that were highly stressed in an accident must be re- placed 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 sec- tion, as that could result in serious inju- ries 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, pas- senger front air bag, front side impact air bags, rear side impact air bags*, win- dow curtain air bags for side windows), ETD (seat belt emergency tensioning de- vice with seat belt force limiters), and front seat knee bolsters. The system is designed to enhance the protection of- fered to properly belted occupants in certain frontal (front air bags and ETD) and side (front side impact air bags, rear side impact air bags*, window curtain air bags and ETD)

impacts which exceed preset deploy- ment thresholds and in certain rollovers (window curtain air bags and ETD).

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 seat belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen. 앫 Never wear seat 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 seat 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 time. Do not fasten a seat belt around a person and another person or other objects.

48

앫 Seat belts should not be worn twisted.

In a crash, you wouldn’t have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries. 앫 Pregnant women should also always 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 restraint, toddler restraint, or booster seat, always follow the child seat manu- facturer’s instructions.

Enhanced seat belt reminder system When the engine is started, the seat belt telltale < will always illuminate for 6 seconds to remind you and your passen- gers to fasten your seat belts. If the driver’s seat belt is not fastened when the engine is started, an additional warning chime will also sound for a maxi- mum of 6 seconds or until the driver’ s seat belt is fastened. If after these 6 seconds the driver’s or the front passenger’s seat belt (with the front passenger seat occupied) is not fastened with front doors closed, 앫 the seat belt telltale < remains illu- minated for as long as either the driv- er’s or front passenger’s seat belt is not fastened.

앫 and if the vehicle speed once exceeds

15 mph (25 km/h), the seat belt telltale < starts flashing and a warning chime sounds with increasing

Safety and Security Occupant safety

intensity for a maximum of 60 seconds or until the driver’s and the front passenger’s seat belt are fastened. If you and/or your front passenger release the seat belt during driving, the seat belt telltale < starts flashing and a warning chime sounds as described before. If the driver’s or the front passenger’s seat belt remains unfastened after 60 seconds, the warning chime stops sounding, the seat belt telltale < stops flashing but continues to be illuminated. After a vehicle standstill, the warning chime reactivates and the seat belt telltale < flashes again when the vehicle speed exceeds 15 mph (25 km/h).

The seat belt telltale < will only go out if both the driver’s and the front passen- ger’s seat belt (with the front passenger seat occupied) are fastened, or the vehicle is standing still and a front door is opened.

For more information, see “Practical hints” (컄 page 380).

Emergency tensioning device (ETD), seat belt force limiter The seat belts are equipped with Emergen- cy Tensioning Devices (ETDs) and seat belt force limiters. The ETD is designed to activate in the following cases: 앫 in frontal or rear-end impacts exceed- ing the system deployment threshold

앫 in certain vehicle rollovers 앫 if the restraint systems are operational

and functioning correctly, see = indicator lamp (컄 page 382)

i The ETDs for the front seats will only acti- vate if the front seat belt is fastened (latch plate properly inserted into buckle). The ETDs for the rear seats will activate with or without the respective seat belt fastened.

In an impact, the ETDs remove slack from the seat belts in such a way that the seat belts fit more snugly against the body. Seat belt force limiters, when activated, are em- ployed to help reduce the peak force exert- ed by the seat belts on occupants during a crash.

i ETDs do not correct an incorrect seat posi- tion or incorrectly worn seat belts. ETDs do not pull occupants back toward the backrest.

Warning!

A pyrotechnic Emergency Tensioning Device (ETD) that was activated must be replaced.

When disposing of the pyrotechnic Emer- gency Tensioning Device (ETD), our safety instructions must be followed. These are available at an authorized Mercedes-Benz Center.

Active head restraints

The active head restraints are intended to offer the driver and front passenger in- creased protection from whiplash type in- juries. In the event of a rear-end collision, the active head restraints on the driver’s and front passenger’s seats are designed to move forward in the direction of travel, providing the head with increased support earlier on in the collision sequence. The ac- tive head restraints move forward whether the seat is occupied or not.

Warning!

Do not attach any objects (e.g. hangers) to the head restraint posts. Otherwise, the ac- tive head restraints may not function prop- erly or offer the degree of protection they were designed for in the event of an acci- dent.

50

If the active head restraints have been trig- gered in an accident, the active head re- straints must be reset. Otherwise, the active head restraints cannot offer any ad- ditional protection in the event of another rear-end collision. For information on resetting the activated active head restraints, see “Resetting acti- vated head restraints” (컄 page 427). You cannot remove the active head re- straint on the driver’s and front passen- ger’s seats. For removal contact an authorized Mercedes-Benz Center.

Warning!

Only use seat or head restraint covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat or head restraint covers may interfere with or prevent the activation of the active head restraints. Contact an authorized Mercedes-Benz Center for avail- ability.

Warning!

For your protection, drive only with properly positioned head restraints.

Adjust head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation.

For information on head restraint adjust- ment, see “Adjusting rear head restraints” (컄 page 89).

Children in the vehicle

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

restraint appropriate to the age and size of the child.

왘 Make sure the infant or child is

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

Warning!

Do not leave children unattended in the ve- hicle, even if they are secured in a child re- straint system. The children could 앫 injure themselves on parts of the vehicle 앫 be seriously or fatally injured through excessive exposure to extreme heat or cold

Do not expose the child restraint system to direct sunlight. The child restraint system’s metal parts, for example, could become very hot, and the child could be burned on these parts.

If children open a door, they could 앫 injure other persons 앫 get out of the car and injure themselves

or be injured by following traffic

Unsecured or improperly positioned cargo increases a child’s risk of injury in the event of 앫 strong braking maneuvers 앫 sudden changes of direction 앫 an accident

Safety and Security Occupant safety

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 acti- vated. The seat 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. To deacti- vate the special seat belt retractor for the front passenger seat, the front passenger seat must be in the most backward posi- tion. The seat belt can again be used in the usual manner.

Warning!

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

i Information on child seats with mounting fit- tings for tether anchorages (컄 page 54). For information on LATCH-type child seat mounts (컄 page 55). The use of infant or child restraints is re- quired by law in all 50 states, the District of Columbia, the U.S. territories and all Ca- nadian provinces. Infants and small children should be seat- ed in an appropriate infant or child re- straint system properly secured in accordance with the manufacturer’s in- structions for the child restraint, that com- plies with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadi- an Motor Vehicle Safety Standards 213 and 210.2.

52

A statement by the child restraint manu- facturer of compliance with these stan- dards can be found on the instruction label on the restraint and in the instruction man- ual provided with the restraint. When using any infant or child restraint system, make sure to carefully read and follow all manufacturer’s instructions for installation and use. Please read and observe warning labels af- fixed to the inside of the vehicle and to infant or child restraints.

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 appropriately sized 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 al- ways sit as upright as possible, properly use the seat belts 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 im- portant 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 serious- ly 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-fac- ing 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.

앫 If you must install a rear-facing child

restraint on the front passenger seat be- cause circumstances require you to do so, make sure the 5/ indicator lamp is illuminated, indicating that the front passenger front air bag is deacti- vated. Should the 5/ indicator lamp not illuminate or go out while the restraint is installed, please check in- stallation.

Safety and Security Occupant safety

Periodically check the 5/ indica- tor lamp while driving to make sure the 5/ indicator lamp is illuminated. If the 5/ 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 serious- ly injured or even killed if the front pas- senger front air bag inflates.

앫 If you have to place a child in a for-

ward-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 ac- cording 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.

Safety and Security Occupant safety

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 seat belt posi- tioning for children over 41 lbs until they reach a height where a lap/shoulder belt fits properly without a booster.

54

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 chil- dren in a child restraint system may use vehicle equipment and may cause an acci- dent and/or serious personal injury.

Installation of infant and child restraint systems

Warning!

Always lock backrest in its upright position when rear seat bench is occupied by pas- sengers, before installing top tether straps, or the extended cargo compartment is not in use. Check for secure locking by pushing and pulling on the backrest. If the seat back- rest is not properly locked, the seat back- rest could fold. The child seat would no longer be properly supported or positioned to provide its intended benefit. That could cause serious or even fatal injuries.

This vehicle is equipped with tether an- chorages for a top tether strap at each of the rear seating positions. Top tether straps enable an additional con- nection to be made between child restraint systems secured with LATCH-type anchors and rear seats. This can further reduce the risk of injury.

tion System)

ABS

Safety and Security Driving safety systems

Always adapt your driving style to the pre- vailing road and weather conditions and keep a safe distance to other road users and objects on the street.

i In winter operation, the maximum effective- ness of the ABS, BAS, EBP, ESP® and 4MATIC is only achieved with winter tires (컄 page 360), or snow chains as required.

The ABS is functional above a speed of approximately 5 mph (8 km/h) indepen- dent 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 26) comes on when you switch on the ignition. It goes out when the engine is running.

Warning!

Warning!

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 driving safety systems described in this section cannot reduce these risks or pre- vent the natural laws of physics from acting on the vehicle.

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.

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 pul- sation.

컄컄

59

Safety and Security Driving safety systems

컄컄

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

Emergency brake maneuver 왘 Keep continuous full pressure on the

brake pedal.

Warning!

When the ABS is malfunctioning, the BAS EBP, ESP® and hill start assist are also switched off.

When the ABS is malfunctioning, the wheels may lock during hard braking, reducing steering capability and extending the brak- ing distance.

60

Warning!

Adaptive Brake

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 afforded. The ABS cannot prevent acci- dents, including those resulting from exces- sive speed in turns, following another vehicle too closely, or hydroplaning.

Only a safe, attentive, and skillful driver can prevent accidents.

The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dan- gerous manner which could jeopardize the user’s safety or the safety of others.

For more information, see “Practical hints” (컄 page 374).

Adaptive Brake provides a high level of braking safety as well as increased braking comfort. It is coupled with ABS, ESP® and BAS. Adaptive Brake takes driver and vehi- cle characteristics into consideration, thus achieving an optimal braking effect.

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. 왘 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!

When the BAS is malfunctioning, the brake system is still functioning normally, but with- out the additional brake boost available that BAS would normally provide in an emergen- cy braking maneuver. Therefore, the braking distance may increase.

Warning!

The BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that af- forded by the condition of the vehicle brakes and tires or the traction afforded. The BAS cannot prevent accidents, including those resulting from excessive speed in turns, fol- lowing another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents.

Safety and Security Driving safety systems

The capabilities of a BAS equipped vehicle must never be exploited in a reckless or dan- gerous manner which could jeopardize the user’s safety or the safety of others.

For more information, see “Practical hints” section (컄 page 374).

EBP

The Electronic Brake Proportioning (EBP) enhances braking effectiveness by allow- ing the rear brakes to supply a greater pro- portion of the braking effort in straight line braking without a loss of vehicle stability.

Warning!

If the EBP malfunctions, the ABS, BAS, ESP® and hill start assist are also switched off.

If the EBP is malfunctioning, the brake sys- tem will still function with full brake boost. However, the rear wheels could lock up dur- ing emergency braking situations, for exam- ple. You could lose control of the vehicle and cause an accident. Adapt your driving style to the changed driving characteristics.

ESP®

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 spin- ning or if the vehicle starts to skid. By ap- plying 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 and steering maneuvers. The ESP® warning lamp v in the instru- ment cluster flashes when the ESP® is en- gaged. The ESP® warning lamp v in the instru- ment cluster comes on when you switch on the ignition (컄 page 82). It goes out when the engine is running.

62

Warning!

Warning!

Never switch off the ESP® when you see the ESP® warning lamp v flashing in the in- strument cluster. In this case proceed as fol- lows: 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 result- ing from excessive speed.

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 ca- pabilities of an ESP® equipped vehicle must never be exploited in a reckless or danger- ous manner which could jeopardize the us- er’s safety or the safety of others.

i The cruise control is switched off when the ESP® engages.

i The ESP® will only function properly if you use wheels of the recommended tire size (컄 page 467).

! Vehicles without 4MATIC: Because the ESP® operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO (Canada only) start/stop button* in 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 oth- erwise seriously damage the brake system. For information on vehicles with 4MATIC, see “Four wheel electronic traction system (4MATIC) with the ESP®” (e page 65).

For more information, see “Practical hints” section (컄 page 380) and (컄 page 387).

Electronic traction system The electronic traction system is a compo- nent of ESP®. The electronic traction system improves the vehicle’s ability to utilize available trac- tion, especially under slippery road condi- tions by applying the brakes to a spinning wheel. When you switch off the ESP®, the elec- tronic traction system is still enabled.

Warning!

If you are driving too fast, the electronic traction system cannot reduce the risk of an accident.

The electronic traction system cannot pre- vent the natural laws of physics from acting on the vehicle.

Safety and Security Driving safety systems

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. Do not switch off the ESP® when a Minispare wheel is mounted.

To improve the vehicle’s traction, switch 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 when driving with snow chains 앫 in deep snow 앫 in sand or gravel

63

Safety and Security Driving safety systems

Warning!

Switch on the ESP® immediately if the afore- mentioned circumstances do not apply any- more. Otherwise the ESP® will not stabilize the vehicle when it is starting to skid or a wheel is spinning.

When you switch off the ESP® 앫 the ESP® does not stabilize the vehicle 앫 the engine output is not limited, which

allows the drive wheels to spin and thus cut into surfaces for better grip

앫 the electronic traction system will still

apply the brakes to a spinning wheel 앫 the ESP® continues to operate when

you are braking

앫 you cannot activate the cruise control 앫 the cruise control switches off if

currently activated

64

i When the ESP® is switched off and one or more drive wheels are spinning, the ESP® warn- ing lamp v in the instrument cluster flashes. However, the ESP® will then not stabilize the ve- hicle.

1 ESP® off/on 왘 With the engine running, press ESP®

switch 1 until the ESP® warning lamp v in the instrument cluster comes on. The ESP® is switched off.

Warning!

When the ESP® warning lamp v is illumi- nated continuously, the ESP® is switched off or is not operational due to a malfunction. Vehicle stability in standard driving maneu- vers reduces.

Adapt your speed and driving to the prevail- ing road conditions and to the non-operating status of the ESP®.

! Avoid spinning of a drive wheel for an ex- tended period with the ESP® switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Lim- ited Warranty.

Switching on the ESP® 왘 Press ESP® switch 1.

The ESP® warning lamp v in the in- strument cluster goes out. You are now again in normal driving mode with the ESP® switched on.

Failure to observe these guidelines could cause the vehicle to skid. The ESP® cannot prevent accidents result- ing from excessive speed.

! Do not tow with one axle raised. Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty.

! Performance testing must only be conduct- ed on a two-axle dynamometer. Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty.

Four wheel electronic traction system (4MATIC) with the ESP®

Models with all-wheel-drive only. The 4MATIC improves vehicle’s ability to use available traction, e.g. during winter operation in mountains under snowy conditions, by applying power to all four wheels.

Warning!

If you see the ESP® warning lamp v flashing in the instrument cluster, 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

Safety and Security Driving safety systems

! Because the ESP® operates automatically, the engine must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO (Canada only) start/stop button* in position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Active braking action through the ESP® may otherwise seriously damage the front or rear axle brake system. Operational tests with the engine running can only be conducted on a two-axle dynamometer.

i At highly demanding operating conditions, the electronic traction system may temporarily switch off to prevent overheating of the drive wheel brakes. The message Currently Un- available See Operator’s Manual will then appear in the multifunction display while the ESP® warning lamp v is flashing. The ESP® is still functioning normally.
