Seats

Important safety notes

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.

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.

WARNING
Your seat belt must be adjusted so that you can correctly fasten your seat belt.

Observe the following points: - adjust the seat backrest until your arms are slightly angled when holding the steering wheel.

- adjust 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.

- 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.

- never 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.

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.

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 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.

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.

To avoid damage to the seats
and the seat heating, observe the following information: - do not spill any liquids on the seats. If liquid is spilled on the seats, dry them as soon as possible.

- if 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.

- clean the seat covers as recommended; see the "Interior care" section.

- do 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.

- when the seat heating is in operation, do not cover the seats with insulating materials, e.g. blankets, coats, bags, seat covers, child seats or booster seats.

When you move the seats, make
sure that there are no objects in the footwell or behind the seats. Otherwise, you could damage the seats and the objects.

When the rear bench seat is
folded forwards, the front seats cannot be moved to their rearmost position. You could otherwise damage the seats and the rear bench seat.

Make sure that the sun visor
is folded up before adjusting the backrest and head restraint height. The head restraint and sun visor could otherwise collide when the head restraint is fully extended.

It is not possible to remove the
head restraints from the front seats. The rearcompartment head restraints can be removed.

Please contact an authorized Mercedes- Benz Center for more information.

Other topics:
- cargo compartment enlargement (folding the rear bench seat forwards).

Rear seat head restraints

WARNING
For safety reasons, always drive with the rear head restraints in the upright position when the rear seats are occupied.

Keep the area around head restraints clear of articles (e.g. clothing) to not obstruct the folding operation of the head restraints.

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

Adjust the head restraint in such a way 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.

With a rear seat occupied, make sure to move the respective head restraint up from the lowest non-use position and have the occupant adjust the head restraint properly.

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

Adjusting the rear seat head restraint height

- If the head restraint is fully lowered, it is necessary to press release catch 1.

- To raise: pull the head restraint up to the desired position.

- To lower: press release catch 1 and push the head restraint down until it is in the desired position.

Adjusting the rear seat head restraint angle

Adjust the head restraints so that they are as close as possible to your head.

You can only adjust the two outer head restraints.
