Driving safety systems Introduction This section contains information about the following driving safety systems: RABS (Antilock Brake System) RBAS (Brake Assist System) REBB (Electronic Brake Booster) RESP® (Electronic Stability Program) i In winter operation, the maximum effectiveness of most of the driving systems described in this section is only achieved with winter tires, or snow chains as required.

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. G Warning! The ABS, the BAS, and the ESP® switch off when the differential locks are switched on. When the ABS, the BAS, and the ESP® are switched off Rwheels may lock during hard braking Rsteering capabilities are reduced Rbraking distance is increased Rvehicle stability in standard driving

maneuvers is increased

Make sure the differential locks are switched on at all times except when driving off-road for example. Switch on the differential locks immediately when returning from off-road driving.

ABS G Observe Safety notes, see page 50. 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. 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 approximately 5 mph (8 km/h) independent of road surface conditions, provided the differential locks are not engaged. On slippery road surfaces, the ABS will respond even to light brake pressure. The ! indicator lamp in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.

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. X Keep firm and steady pressure on the brake

pedal while you feel the pulsation.

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 indication of hazardous road conditions and

Driving safety systems

functions as a reminder to take extra care while driving.

Emergency brake maneuver X Keep continuous full pressure on the brake

pedal. G Warning! If the ABS malfunctions, other driving safety 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 steering capability and extending the braking distance.

LOW-RANGE ABS During off-road driving, a special low-range system for the ABS is operational with the transfer case in position LOW (Y page 91). An improved braking action (dig-in effect) is obtained for vehicles speeds of up to 37 mph (60 km/h) through a change in the ABS control function.

BAS G Observe Safety notes, see page 50. The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, thereby potentially reducing the braking distance. X 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. G Warning! If the BAS malfunctions, the brake system still functions, but without the additional brake

52 Driving safety systems

boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.

EBB G Observe Safety notes, see page 50. The Electronic Brake Booster (EBB) enhances braking effectiveness by allowing the rear brakes to supply a greater proportion of the braking effort in straight-line braking without a loss of vehicle stability. G Warning! If the EBB malfunctions, the brake system is still functioning. However, the rear wheels may lock up during hard braking. You may to lose control over the vehicle and possibly cause an accident. Adjust your driving style to the non-operating status of the EBB.

ESP® G Observe Safety notes, see page 50. The Electronic Stability Program (ESP®) is operational as soon as the engine is running 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 individual wheels 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 d in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.

The ESP® warning lamp d in the instrument cluster flashes when the ESP® is engaged. G Warning! Never switch off the ESP® when you see the ESP® warning lamp d flashing in the instrument cluster. In this case proceed as follows: RWhen driving off, apply as little throttle as

possible.

RWhile driving, ease up on the accelerator

pedal.

RAdapt 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.

! Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty.

! Because the ESP® operates

automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Such testing should be no longer than 10
seconds. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

! The ESP® will only function properly if you use wheels of the recommended tire size as specified in the “Technical data” section of this Operator’s Manual.

Electronic Traction System (4-ETS) G Observe Safety notes, see page 50. The 4-ETS (four-wheel Electronic Traction System) is a component of the ESP®. The 4-ETS improves the vehicle’s ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. In addition, more power is transferred to the wheel(s) with traction. The 4-ETS function is available between vehicle speeds of 0 mph (km/h) and 37 mph (60 km/h). When you switch off the ESP®, the 4-ETS is still enabled.

Switching off the ESP® G Warning! The ESP® should not be switched off during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers. To improve the vehicle’s traction, switch off the ESP® in driving situations in which it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: Rwhen driving with snow chains Rin deep snow Rin sand or gravel Rwhen driving off-road G Warning! Switch on the ESP® immediately if the aforementioned circumstances do not apply anymore. Otherwise the ESP® will not stabilize the vehicle when it is starting to skid or a wheel is spinning.

G Warning! Do not adjust the driver’s seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle. 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 fatal injuries. The seat backrest and seat belts provide the best restraint when the wearer is in a position that is as upright as possible and seat belts are properly positioned on the body. G Warning! Your seat must be adjusted so that you can correctly fasten your seat belt. Observe the following points: RAdjust the seat backrest until your arms are slightly angled when holding the steering wheel.

RAdjust the seat to a comfortable seating position that still allows you to reach the accelerator/brake pedal safely. The position should be as far back as possible with the driver still able to operate the controls properly.

RAdjust the 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.

RNever place hands under the seat or near

any moving parts while a seat is being adjusted.

Failure to do so could result in an accident and/or serious personal injury. G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that

Seats

63

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. For additional information, see “Children in the vehicle”. 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! For your protection, drive only with properly positioned head restraints. Adjust the 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. Do not drive the vehicle without the seat head restraints. Head restraints are intended to help reduce injuries during an accident.
