2012 Mercedes-benz GL Class Owners Manual

The NECK-PRO head restraints increase protection to the driver's and front passenger's head and neck. To this end, the NECK-PRO head restraints on the driver's and front-passenger seats are moved forwards and upwards in the event of a rear-end

collision of a certain severity. This provides better head support. G WARNING Do not secure any objects (e.g. coat hangers) on the NECK-PRO head restraints. Otherwise, the NECK-PRO head restraints may not function properly, or in the event of a rear-end collision may not be able offer the level of protection they are designed to provide.

If the NECK-PRO head restraints have been triggered in an accident, reset the NECK-PRO head restraints on the driver’s and front- passenger seat (Y page 54). Otherwise, the additional protection will not be available in the event of another rear-end collision. You can recognize when NECK-PRO head restraints have been triggered by the fact that they have moved forwards and can no longer be adjusted.

Seat belts Important safety notes The use of seat belts and infant and child restraint systems is required by law in all 50
states, the District of Columbia, the U.S. territories and all Canadian provinces. Even where this is not the case, all vehicle occupants should have their seat belts fastened when the vehicle is in motion. i For further information on infants and children traveling in the vehicle and on infant and child restraint systems, see "Children in the vehicle" (Y page 61). G WARNING Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts. Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat

56 Occupant safety

belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts. G WARNING Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body. G WARNING Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time. G WARNING Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced 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 their failure to activate when necessary. Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.

Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center.

Correct use of the seat belts G WARNING USE SEAT BELTS PROPERLY RSeat 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 the event of an accident.

REach occupant should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, including rollovers. The integrated restraint system includes SRS (driver front air bag, driver's side knee bag, front-passenger front air bag, side impact air bags, window curtain air bags for the side windows), Emergency Tensioning Devices, seat belt force limiters, and front seat knee bolsters. The system is designed to enhance the protection offered to properly belted occupants in certain frontal (front air bags, driver's side knee bag and ETDs) and side (side impact air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds and in certain rollovers (window curtain air bags and ETDs).

RNever wear the shoulder belt under your

arm, across your neck or off your shoulder. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. 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. Adjust the seat belt so that the shoulder section is located as close as possible to the middle of the shoulder. It should not touch the neck. Never pass the shoulder

portion of the seat belt under your arm. For this purpose, you can adjust the height of the seat belt outlet.

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

RNever wear seat belts over rigid or

breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries.

RMake sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing.

RNever 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 at the same time.

RSeat belts should not be worn twisted. In a crash, you would not have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries.

RPregnant 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.

RPlace the seat backrest in a position that is

as upright as possible.

RCheck your seat belt during travel to make

sure it is properly positioned.

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.

RWhen using a seat belt to secure infant

restraints, toddler restraints, or children in booster seats, always follow the child seat manufacturer's instructions. G WARNING Do not pass seat belts over sharp edges. They could tear.

Occupant safety

57

Do not allow the seat belt to get caught in the door or in the seat adjustment mechanism. This could damage the seat belt. Never attempt to make modifications to seat belts. This could impair the effectiveness of the seat belts.

Fastening seat belts 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 seat whenever possible. Regardless of seating position, children 12
years old and under must be seated and properly secured in an appropriately sized child restraint system or booster seat recommended for the size and weight of the child. For additional information, see the "Children in the vehicle" section. 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. G WARNING Canada only: children 12 years old and under may ride on the front seat if a BabySmart™ compatible child restraint system is installed on the front-passenger seat. Use only Mercedes-Benz approved BabySmart™ compatible child restraint systems. A BabySmart™ compatible child restraint system will deactivate the front-passenger front air bag when installed correctly. The front-passenger front air bag will not be deactivated if the child restraint systems that are installed are not BabySmart™ compatible or if BabySmart™ compatible child restraint systems are not installed correctly. If the front-passenger front air bag is deployed in a collision, the child will be struck by the air bag. If this happens, serious or fatal injury will result.

If the driver or front passenger have not fastened their seat belt after 6 seconds and the doors are closed, the 7 seat belt warning lamp lights up. Runtil the driver or the front passenger have

fastened their seat belts

Rif a vehicle speed of 15 mph(25 km/h) is

exceeded once, a warning tone with increasing intensity sounds additionally for a maximum of 60 seconds or until the driver or front passenger have fastened their seat belts.

If the driver or front passenger undo their seat belts during the journey, the 7 seat belt warning lamp lights up and the warning tone sounds again. The warning tone ceases even if the driver or front passenger have still not fastened their seat belt after 60 seconds. The 7 seat belt warning lamp stops flashing but continues to be lit. Once the vehicle is stationary, the warning tone is reactivated and the 7 seat belt warning lamp starts to flash again if the vehicle speed exceeds 15 mph(25 km/h) once. The 7 seat belt warning lamp only goes out if: Rboth the driver and the front passenger

have fastened their seat belts.

or Rthe vehicle is stationary and a door is open. i For more information on the 7 seat

belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belt" (Y page 258).

Emergency Tensioning Devices, belt force limiters The seat belts for the front seats are equipped with ETDs/belt buckle tensioners and seat belt force limiters. The outer seat belts in the second row of seats are equipped with ETDs

60 Occupant safety

and seat belt force limiters. The seat belts for the third row of seats are equipped with ETDs. The ETDs/belt buckle tensioners tighten the seat belts in an accident, pulling them close against the body. The ETDs/belt buckle tensioners do not correct incorrect seat positions or incorrectly fastened seat belts. The ETDs do not pull vehicle occupants back towards the backrest. Seat belt force limiters, when triggered, help to reduce the peak force exerted by the seat belt on the vehicle occupant. The seat belt force limiters for the front seats are synchronized with the front air bags. These take on a part of the deceleration force. Thus, the force exerted on the occupant is distributed over a greater area. The ETDs/belt buckle tensioners can only be activated when: Rthe ignition is switched on. Rthe restraint systems are operational; see

"SRS warning lamp" (Y page 38)

Rthe belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front. Rthe front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side.

The ETDs on the outside seats in the second row and on the seats in the third row are triggered independently of the lock status of the seat belts. The ETDs are triggered depending on the type and severity of an accident: Rif, in the event of a head-on or rear-end

collision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact

Rif, in the event of a side impact, on the side

opposite the impact the vehicle

decelerates or accelerates rapidly in a lateral direction

Rif in certain situations where the vehicle

overturns and the system determines that it can provide additional protection

If the Emergency Tensioning Device/belt buckle tensioners are triggered, 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. The + SRS warning lamp lights up. i If the belt buckle tensioners have been

triggered on the front seats, the buckle will be pulled down and will be almost flush with the upper edge of the seat. The + SRS warning lamp is lit. G WARNING The belt buckle tensioners on the front seats only function if the belt buckles can be pulled down unobstructed. They must not be restricted in any way. Therefore, do not grab the belt buckles and do not place any objects under the belt buckles. Otherwise, the tensioning of the belt by the buckle is restricted or will not function, and will not provide any additional protection. G WARNING Pyrotechnical ETDs/belt buckle tensioners that were activated must be replaced. For your safety, when disposing of the pyrotechnic ETDs/belt buckle tensioners always follow our safety instructions. These instructions are available from any authorized Mercedes-Benz Center. The PRE-SAFE® system is equipped with electrically reversible pre-tensioners that do not need replacing after deployment.

! If the front-passenger seat is not

occupied, do not engage the seat belt tongue in the buckle on the front- passenger seat. Otherwise, the Emergency Tensioning Device/belt buckle tensioner

could be triggered in the event of an accident.

Children in the vehicle Child restraint systems Important safety notes We recommend that all infants and children be properly secured in an infant or child restraint system at all times while the vehicle is in motion. 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. Infants and children must always be seated in an appropriate infant or child restraint system recommended for the size and weight of the child. The infant or child restraint system must be properly secured in accordance with the manufacturer's instructions. All infant or child restraint systems must meet U.S. Federal Motor Vehicle Safety Standards 213
and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. An information label on the child restraint system indicates whether it meets these standards. This information is also provided in the installation instructions supplied with the child restraint system. Always read and follow the manufacturer's instructions when using an infant or child restraint system or booster seat. Observe all warning signs in the vehicle interior and on the infant or child restraint. G WARNING Accident statistics show that children secured in the rear seats are safer than children secured in the front-passenger seat. For this reason, we strongly advise that you always secure children in the rear seats. Regardless of the seat position, children under 12 years must be secured correctly in a suitable infant or child restraint system or

Children in the vehicle

61

booster seat suitable for the size and weight of the child. The infant or child restraint system must be correctly secured using the vehicle's seat belt, the seat belt and Top Tether belt or the lower anchorages and the Top Tether belt in complete accordance with the child seat manufacturer's instructions. Occupants, in particular children, must sit as upright as possible, fasten the seat belt correctly and use a suitable infant restraint system, child restraint system or booster seat suitable for the size and weight of the child. Children can be seriously or even fatally injured by an air bag deploying. Observe the following important information if it is absolutely necessary to carry a child on the front-passenger seat: RUSA only: Your vehicle is equipped with air

bag technology that is designed to deactivate the front-passenger front air bag, when the system on the front- passenger seat detects the weight of a typical 12-month old child in a standard child restraint.

RUSA only: For children that weigh more

than a typical 12-month old child, the front- passenger front air bag can be activated or deactivated. Always make sure that the 42 indicator lamp is illuminated indicating that the front- passenger front air bag is deactivated. RCanada only: Children 12 years old and

under may ride on the front seat if a BabySmart™ compatible child restraint system is installed on the front-passenger seat. Use only Mercedes-Benz approved BabySmart™ compatible child restraint systems. A BabySmart™ compatible child restraint system will deactivate the front- passenger front air bag when installed correctly. The front-passenger front air bag will not be deactivated if the child restraint systems that are installed are not BabySmart™ compatible or if BabySmart™ compatible child restraint systems are not

62

Children in the vehicle

installed correctly. If the front-passenger front air bag is deployed in a collision, the child could be struck by the air bag. This could lead to serious or fatal injury.

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 way to completely rule out this risk is by making sure you never place a child in a rearward-facing child restraint system on the front- passenger seat. For this reason, we strongly advise that you always carry children in a rearward-facing child restraint system on a rear seat.

RIf you must install a rear-facing child restraint on the front-passenger seat because circumstances require you to do so, make sure the 42
indicator lamp is illuminated, indicating that the front-passenger front air bag is deactivated. If the 42
indicator lamp does not light up or goes out when the child restraint system is installed, check the anchorages of the restraint system. Check the 42
indicator lamp regularly while driving to ensure that the 42 indicator lamp is illuminated. If the 42
indicator lamp lights up or remains out, you may only carry a child on the front- passenger seat once 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.

Rwhen securing a child in a child restraint system on the front-passenger seat, you must: - move the front-passenger seat as far

back as possible

- use a child restraint system that is

suitable for the age, size and weight of the child

- observe the manufacturer's installation instructions in order to install and secure the child restraint system correctly. RFor children larger than the typical 12-

month-old child, the front-passenger front air bag can be activated or deactivated. G 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. Position the shoulder belt across the chest and shoulder, not face or neck. A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a booster. 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.

If an infant or child is traveling in the vehicle: X Secure the infant or child with an

appropriate infant or child restraint

recommended for the child's age and weight.

X Make sure that the infant or child is

properly secured at all times while the vehicle is in motion. G WARNING When leaving the vehicle, always remove the SmartKey from the ignition lock. Always take the SmartKey with you and lock the vehicle. Do not leave children unattended in the vehicle, even if they are secured in a child restraint system, or with access to an unlocked vehicle. A child's unsupervised access to a vehicle could result in an accident and/or serious personal injury. The children could: Rinjure themselves on parts of the vehicle Rbe seriously or fatally injured through

excessive exposure to extreme heat or cold Rinjure themselves or cause an accident with

vehicle equipment that can be operated even if the SmartKey is removed from the ignition lock or removed from the vehicle, such as seat adjustment, steering wheel adjustment, or the memory function

If children open a door, they could injure other persons or get out of the vehicle and injure themselves or be injured by following traffic. 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. G WARNING Do not carry heavy or hard objects in the passenger compartment or trunk unless they are firmly secured in place. Unsecured or improperly positioned cargo increases a child's risk of injury in the event of Rstrong braking maneuvers Rsudden changes of direction Ran accident

Important safety notes G WARNING The following factors increase the risk of accidents: RExcessive speed, especially in turns RWet and slippery road surfaces RFollowing another vehicle too closely The driving safety systems described in this section cannot reduce these risks or prevent the natural laws of physics from acting on the vehicle. They cannot increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a vehicle equipped with the driving safety systems described in this section must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others. Always adjust your driving style to the prevailing road and weather conditions and keep a safe distance to other road users and objects on the street. If a driving system malfunctions, other driving safety systems may also switch off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear.

i Please note that the driving safety

systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Pay particular attention to the information regarding tires, recommended minimum tire tread depths etc. in the "Wheels and tires" section (Y page 338). In wintry driving conditions, always use winter tires (M+S tires) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible.

ABS (Anti-lock Braking System) Important safety notes i Observe the "Important safety notes"

section (Y page 68).

ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. ABS works from a speed of about 5 mph(8 km/h) upwards, regardless of road- surface conditions. ABS works on slippery surfaces, even when you only brake gently. G WARNING If the ABS malfunctions, other driving systems such as the BAS or the ESP® are also switched off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear. If the ABS malfunctions, the wheels may lock during hard braking, reducing the steering capability and extending the braking distance.

The ! warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running.

Braking If ABS intervenes when braking, you will feel a pulsing in the brake pedal. X If ABS intervenes: continue to depress the

brake pedal with force until the braking situation is over.

X To make a full brake application:

depress the brake pedal with full force.

The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving. G WARNING Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pumping the brake pedal defeats the purpose of the ABS

and significantly reduces braking effectiveness.

Off-road ABS An ABS mode specifically suited to off-road terrain is activated automatically if the off- road drive program (Y page 206) is activated or the LOW RANGE (Y page 206) off-road gear is selected. At speeds below 18 mph(30 km/h), the front wheels lock periodically when braking. The digging-in effect achieved in the process reduces the stopping distance on off-road terrain. This limits steering capability.

BAS (Brake Assist System) i Observe the "Important safety notes"

section (Y page 68).

BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. X Keep the brake pedal firmly depressed until

the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. G WARNING If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.

ESP® (Electronic Stability Program) Important safety notes i See the "Important safety notes" section

(Y page 68).

If ESP® detects that the vehicle is deviating from the direction desired by the driver, one

Driving safety systems

69

or more wheels are braked to stabilize the vehicle. If necessary, the engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. G WARNING Under no circumstances should you deactivate ESP® when the ÷ ESP® warning lamp in the instrument cluster flashes. Proceed as follows: Rwhen driving off, apply as little throttle as

possible.

Rwhile driving, ease up on the accelerator

pedal.

Radapt your speed to suit the prevailing road

and weather conditions.

Failure to observe these guidelines could cause the vehicle to skid. ESP® cannot prevent accidents resulting from excessive speed.

! Only operate the vehicle for a maximum

of ten seconds on a brake test dynamometer. Switch off the ignition. Application of the brakes by ESP® may otherwise destroy the brake system.

! Function or performance tests may only be performed on a 2-axle dynamometer. If you wish to operate the vehicle on such a dynamometer, please consult an authorized Mercedes-Benz Center beforehand. You could otherwise damage the drive train or the brake system.

i Only use wheels with the recommended

tire sizes. Only then will ESP® function properly.

70 Driving safety systems

4ETS (Electronic Traction System) i Observe the "Important safety notes"

section (Y page 68).

Traction control is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. In addition, more drive torque is transferred to the wheel or wheels with traction. Traction control remains active if you deactivate ESP®. X Activate the off-road drive program

(Y page 206) or engage the LOW RANGE (Y page 206) off-road gear if appropriate for the driving conditions. G WARNING Traction control cannot reduce the risk of an accident if you drive too fast. Traction control cannot override the laws of physics.

Off-road 4ETS (Electronic Traction System) A 4ETS system specifically suited to off-road terrain is activated automatically if the off- road drive program is activated (Y page 206) or the LOW RANGE (Y page 206) off-road gear is selected.

Deactivating/activating ESP® i Observe the "Important safety notes"

section (Y page 68). G WARNING ESP® should not be deactivated during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers. Do not deactivate ESP® when the emergency or spare wheel is mounted.

ESP® is activated automatically when the engine is started. It may be best to deactivate ESP® in the following situations: Rwhen using snow chains Rin deep snow Ron sand or gravel G WARNING Switch on ESP® immediately if one of the previously stated conditions is no longer met. Otherwise, ESP® cannot stabilize the vehicle if it begins to lurch or when a wheel spins.

When you deactivate ESP®: RESP® no longer improves driving stability. Rthe engine's torque is no longer limited and the drive wheels can spin. The spinning of the wheels results in a cutting action, which provides better grip.

Rtraction control is still activated. RESP® still provides support when you

brake.

If ESP® is deactivated and one or more wheels start to spin, the ÷ ESP® warning lamp in the instrument cluster flashes. In such situations, ESP® will not stabilize the vehicle.

X To deactivate: press button :.

The å ESP® OFF warning lamp in the instrument cluster lights up.

G WARNING When the å ESP® OFF warning lamp is lit, ESP® is deactivated. If the ÷ ESP® warning lamp and the å ESP® OFF warning lamp remain lit, ESP® is not available due to a malfunction. When ESP® is deactivated or not operational, vehicle stability in standard driving maneuvers is reduced. Adapt your speed and driving to the prevailing road conditions and to the non-operating status of the ESP®.

! Avoid spinning the driven wheels for an extended period with ESP® deactivated. You could otherwise damage the drivetrain.

X To activate: press button :.

The å ESP® OFF warning lamp in the instrument cluster goes out.

Off-road ESP® An ESP® system specifically suited to off-road terrain is activated automatically if the off- road drive program is activated (Y page 206)or if the LOW RANGE (Y page 206) off-road gear is selected. It intervenes with a delay if there is oversteering or understeering, thus improving traction.

ESP® trailer stabilization If your vehicle with trailer (vehicle/trailer combination) begins to lurch, you can only stabilize the vehicle/trailer combination by depressing the brake firmly. In this situation, ESP® assists you and can detect if the vehicle/trailer combination begins to lurch. ESP® slows the vehicle down by braking and limiting the engine output until the vehicle/trailer combination has stabilized. Trailer stabilization is active from a speed of approximately 40 mph(65 km/h).

Driving safety systems

71

G WARNING The system will not be able to assist when the trailer jackknifes Rif the ESP® has switched off due to a

malfunction

Ron wet or icy roads Ron roads with slippery surface Rin sand or gravel Trailers with a high center of gravity may tip over before the system recognizes swaying of the trailer.

Trailer stabilization does not work if ESP® is deactivated or disengaged because of a malfunction.

EBD (electronic brake force distribution) i Observe the "Important safety notes"

section (Y page 68).

EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. G WARNING If EBD has malfunctioned, the braking system remains available with full brake boosting effect. However, the rear wheels can still lock, e.g. under full braking. This could cause you to lose control of your vehicle and cause an accident. You should therefore adapt your driving style to the different handling characteristics.

X Observe the notes on warning and indicator

lamps (Y page 260) as well as display messages (Y page 235).

Theft deterrent locking systems

Distance warning function (vehicles with DISTRONIC) This function provides a warning from a speed of approximately 20 mph(30 km/h), if: Rfor a period of several seconds, the

distance to the vehicle in front is too short for the speed at which you are traveling. The · distance warning lamp in the instrument cluster will light up.

Ryou are rapidly approaching the vehicle in

front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster. You must apply the brakes yourself in order to maintain the appropriate distance to the vehicle in front and prevent a collision. G WARNING If the distance warning lamp · in the instrument cluster comes on while driving and/or an intermittent warning sounds, immediate attention on the part of the driver is required. As required by the traffic situation, apply the brakes and navigate around a possible obstacle. However, do not drive by relying on the distance warning function, as this will result in an emergency braking application. This will not always enable you to avoid a collision, especially when traveling on varying road surface conditions and with varying driver reaction. Complex driving situations are not always fully recognized by the distance warning function. This could result in wrong or missing distance warnings.

X To activate/deactivate: activate or

deactivate the distance warning function in the on-board computer (Y page 228). After activation, the Ä symbol is displayed in the lower multifunction display.

Theft deterrent locking systems Immobilizer The immobilizer prevents your vehicle from being started without the correct SmartKey.
