installed, please check installation. Periodically check the 4 / indicator lamp while driving to make sure the 4 / indicator lamp is illuminated. If the 4 / 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.

RIf 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. G WARNING Infants and small children should never share a seat belt with another occupant. In the event of 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 that are too large for a child restraint must travel in seats using normal 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.

Driving safety systems Driving safety systems overview In this section, you will find information about the following driving safety systems: RABS (Anti-lock Braking System)

(Y page 61)

RBAS (Brake Assist System) (Y page 61) RAdaptive brake lamps (Y page 62) RESP® (Electronic Stability Program)

REBD (electronic brake force distribution)

(Y page 62)

(Y page 64)

RADAPTIVE BRAKE(Y page 64) RTrailer stabilization

Important safety notes 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.

If you fail to adapt your driving style or become distracted, the driving safety systems can neither reduce the risk of accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. i Please note that the driving safety

systems described only work as effectively as possible if 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 318). 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 60). 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. G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.

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. Provided that the differential locks are not active, ABS works from a speed of about 5 mph (8 km/h) upwards, regardless of road- surface conditions. ABS works on slippery surfaces, even if you only brake gently. The yellow ! ABS 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.

Driving safety systems

61

X If ABS intervenes: continue to depress the

brake pedal vigorously 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.

Off-road ABS If the LOW RANGE shift range is selected by the transfer case, (Y page 199), an ABS system specifically suited to off-road terrain is automatically activated. At speeds below 37 mph (60 km/h), the front wheels lock cyclically during 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 60). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking.

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.

62 Driving safety systems

Adaptive brake lamps If you brake sharply from a speed of more than 30 mph (50 km/h) or if braking is assisted by BAS, the brake lamps flash rapidly. In this way, traffic traveling behind you is warned in an even more noticeable manner. If you brake sharply from a speed of more than 45 mph (70 km/h) to a standstill, the hazard warning lamps are activated automatically. If the brakes are applied again, the brake lamps light up continuously. If you drive faster than 6 mph (10 km/h), the hazard warning lamps are deactivated automatically. You can also switch off the hazard warning lamps using the hazard warning button (Y page 104).

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

section (Y page 60). G WARNING If ESP® is malfunctioning, ESP® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop.

! 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.

! A function or performance test should

only be carried out on a two-axle dynamometer. Before you operate the vehicle on such a dynamometer, please consult a qualified workshop. You could otherwise damage the drive train or the brake system.

ESP® monitors driving stability and traction. Traction is the power transmission between the tires and the road surface. ESP® is deactivated if the å warning lamp in the instrument cluster lights up continuously when the engine is running. If the ÷ warning lamp and the å warning lamp are lit continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 252) and any display messages that appear in the instrument cluster (Y page 226). If ESP® detects that the vehicle is deviating from the direction desired by the driver, one 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 ÷ warning lamp flashes in the instrument cluster. If ESP® intervenes: X Do not deactivate ESP® under any

circumstances.

X Only depress the accelerator pedal as far

as necessary when pulling away.

X Adapt your driving style to suit the

prevailing road and weather conditions.

i Only use wheels with the recommended

tire sizes. Only then will ESP® function properly.

i If differential locks are switched on, ABS,

BAS and ESP® switch themselves off automatically.

4ETS (Electronic Traction System) Traction control remains active if you deactivate ESP®.

X If appropriate for the driving conditions, engage the LOW RANGE off-road gear (Y page 199).

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®. At speeds above approximately 37 mph (60 km/h), traction control is no longer active. 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.

Deactivating/activating ESP® G WARNING If you deactivate ESP®, ESP® no longer stabilizes the vehicle. There is an increased risk of skidding and an accident. Only deactivate ESP® in the situations described in the following.

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

Driving safety systems

63

X To deactivate: press button : until the

å warning lamp lights up in the instrument cluster.

X To activate: press button : until the

å warning lamp goes out in the instrument cluster.

ESP® is activated automatically when the engine is started. i Vehicles with the ECO start/stop function: the ECO start/stop function automatically switches the engine off when the vehicle comes to a stop. The engine starts automatically when the driver wants to pull away again. ESP® remains in its previously selected status. Example: if ESP® was deactivated before the engine was switched off, ESP® remains deactivated when the engine is switched on again.

It may be best to deactivate ESP® in the following situations: Rwhen using snow chains Rin deep snow Ron sand or gravel If 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.

64

Theft deterrent locking system

RESP® still provides support when you

brake.

Rand are driving at above 37 mph

(60 km/h), ESP® still intervenes when one wheel reaches its grip limit even though it is switched off.

i If ESP® is deactivated and one or more

wheels start to spin, the ÷ warning lamp in the instrument cluster flashes. In such situations, ESP® will not stabilize the vehicle.

i If ESP® is deactivated, it is automatically

reactivated when you drive faster than 37 mph (60 km/h) or if a predefined lateral acceleration threshold has been exceeded.

Trailer stabilization G WARNING If road and weather conditions are poor, trailer stabilization will not be able to prevent the vehicle/trailer combination from swerving. Trailers with a high center of gravity can tip over before ESP® can detect this. There is a risk of an accident. Always adapt your driving style to the prevailing road and weather conditions.

Trailer stabilization does not work if ESP® is deactivated because of a malfunction. 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 above speeds of about 37 mph (60 km/h).

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

section (Y page 60). G WARNING If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified specialist workshop.

Observe information regarding indicator and warning lamps (Y page 250) as well as display messages (Y page 228). EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking.

ADAPTIVE BRAKE ADAPTIVE BRAKE provides increased braking safety. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 192) and hill start assist (Y page 141).

Theft deterrent locking system Immobilizer X To activate: remove the SmartKey from

the ignition lock.

X To deactivate: switch on the ignition. The immobilizer prevents your vehicle from being started without the correct SmartKey. When leaving the vehicle, always take the SmartKey with you and lock the vehicle.
