The seat belt should: Rfit snugly across your body Rbe routed across the middle of your

shoulder

Rbe routed in your pelvic area across the

hip joints

X Before starting off, adjust the rear-view

mirror and the exterior mirrors (Y page 112) in such a way that you have a good view of road and traffic conditions. X Vehicles with a memory function: save the seat, steering wheel and exterior mirror settings (Y page 114).

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 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.

100 Seats

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.

! To avoid damage to the seats and the seat heating, observe the following information: Rkeep liquids from spilling 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 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. 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.

Rear seat head restraints G 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. G 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 seats in the second and third rows Important safety notes G WARNING 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 belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body. Your seat belt must be adjusted so that you can correctly fasten your seat belt. Never place hands under the seat or near any moving parts while a seat is being adjusted. After adjusting the seat, always ensure that the seat and the backrest are correctly engaged. The backrest must be in an upright position. Test the stability of the latch by pushing and pulling the backrest. If the seat and backrest are not correctly latched, the seat could move forward and the backrest could fold down. While braking, changing direction, or in an accident, you could slide out from under the seat belt. The child seat would no longer be correctly supported or correctly positioned and would no longer carry out its intended function. This could cause serious or fatal injuries.

Adjusting the backrest angle (2nd row of seats) G WARNING The seat belt only offers its intended protection when the seat backrest is in a nearly vertical position and the occupant is sitting upright. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as

possible and the seat belt is properly positioned on the body. You should therefore adjust the seat backrest to a position as upright as possible.

The backrest angle can be adjusted to five positions.

X Pull backrest release ; in the direction of

the arrow and hold it in this position. Backrest : folds forwards.

X Adjust the backrest angle as desired. X Release backrest release ;. X Lean back firmly against the backrest to
