Sliding sunroof

The tilt/sliding panel operates differently when the roof panel switch is pressed and held. See the relevant section in this chapter for details. The opening/closing procedure of the tilt/ sliding panel can be immediately halted by releasing the roof panel switch or, if the roof panel switch was moved past the resistance point and released, by moving the roof panel switch in any direction. G Warning! The panorama roof with tilt/sliding panel is made out of glass. In the event of an accident, the glass may shatter. This may result in an opening in the roof. In a vehicle rollover, occupants not wearing their seat belts or not wearing them properly may be thrown out of the opening. Such an opening also presents a potential for injury for occupants wearing their seat belts properly as entire body parts or portions of them may protrude from the passenger compartment.

! Only open the sliding sunroof if it is free of snow and ice. Otherwise, malfunctions may occur. Do not allow anything to protrude from the sliding sunroof. Otherwise, the seals could be damaged.

! If the sliding sunroof cannot be opened or

closed due to a malfunction, contact a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

! Do not forget that the weather can

change abruptly. Make certain that the sliding sunroof is closed when you leave the vehicle. The vehicle electronics can be damaged if water enters the vehicle interior.

i Resonance noises can occur in addition to the usual airflow noises when the sliding sunroof is open. They are caused by minor pressure fluctuations in the vehicle interior. Change the position of the sliding sunroof

or open a side window slightly to reduce or eliminate these noises.

Operating the sliding sunroof Opening and closing i You can still operate the tilt/sliding

sunroof even if you switch off the engine or remove the SmartKey. This function remains active for five minutes or until one of the front doors is opened.

Overhead control panel : To raise ; To open = To close X Switch on the ignition. X Push or pull the 2 switch in the

Seats Important safety guidelines 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 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. 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.

100 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.

Rwhen the seat heating is in operation, do

not cover the seats with insulating materials, e.g. covers, 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 outer seats in the second row are folded down, the front seats must not be in their rearmost position. The front seats and the outer seats in the second row could otherwise be damaged.

! 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.
