56 Driving safety systems

4ETS (Electronic Traction System) G WARNING Observe "Important safety notes" (Y page 53).

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®. Traction control is no longer active at speeds above approximately 37 mph (60 km/h).

Deactivating/activating 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.

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.

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. RESP® still provides support when you

brake.

Rand drive over 37 mph (60 km/h), ESP®

intervenes when the grip limit of a wheel is reached, even if it is deactivated.

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. If you have deactivated ESP®, it is automatically reactivated if you exceed a speed of 37 mph (60 km/h) or a certain lateral acceleration.

X To deactivate: press button : until the

å warning lamp lights up in the instrument cluster. 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 : until the

å warning lamp goes out in the instrument cluster.

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

section (Y page 53).

EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. G WARNING If the EBD malfunctions, the brake system will still function with full brake boost. However, the rear wheels could lock up during emergency braking situations, for example. You could lose control of the vehicle and cause an accident. Adapt your driving style to the changed driving characteristics.

Theft deterrent locking systems Immobilizer The immobilizer prevents your vehicle from being started without the correct key. When leaving the vehicle, always take the SmartKey with you and lock the vehicle. The engine can be started by anyone with a valid SmartKey that is left inside the vehicle. X To activate: remove the SmartKey from

the ignition lock.

X To deactivate: switch on the ignition. i The immobilizer is always deactivated

when you start the engine. In the event that the engine cannot be started when the starter battery is fully charged, the immobilizer may be faulty.

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Please read the information on qualified

specialist workshops (Y page 20).

Correct driver's seat position

Observe the safety guidelines on (Y page 75). X Check whether you have adjusted seat =

properly. Electrical seat adjustment (Y page 76). When adjusting the seat, make sure: Ryou are as far away from the driver's air

bag as possible.

Ryou are sitting in a normal upright

position.

Ryou can fasten the seat belt properly. Ryou have moved the backrest to an

almost vertical position.

Ryou have set the seat cushion angle so that your thighs are gently supported. Ryou can depress the pedals properly.

X Check whether the head restraint is

adjusted properly (Y page 77). When doing so, make sure that you have adjusted the head restraint so that the back of your head is supported at eye level by the center of the head restraint. Observe the safety guidelines on (Y page 75). X Check whether steering wheel : is

Seats Important safety notes G WARNING In order to avoid possible loss of vehicle control, all seat, head restraint, steering wheel and rear view mirror adjustments, as well as fastening of seat belts, must be done before setting the vehicle in motion. 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 travel 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. This 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 belt 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 The electrically adjustable seats can be operated at any time. Therefore, do not leave children unattended in the vehicle, 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. 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 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.

76

Seats

Do not drive the vehicle without the seat head restraints. Head restraints are intended to help reduce injuries during an accident.

! To avoid damage to the seats and the seat heating, observe the following information: Rdo not spill any liquids on the seats. If

liquid is spilled on the seats, dry them as soon as possible.

Rif the seat covers are damp or wet, do not

switch on the seat heating. The seat heating should also not to be used to dry the seats.

Rclean the seat covers as recommended;

see the "Interior care" section.

Rdo not transport heavy loads on the

seats. Do not place sharp objects on the seat cushions, e.g. knives, nails or tools. The seats should only be occupied by passengers, if possible.
