Vehicle equipment

i This manual describes all the standard and optional equipment of your vehicle which was available at the time of purchase. Country-specific differences are possible. Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions.

Correct driver's seat position

Observe the safety guidelines on (Y page 93). X Check whether you have adjusted seat =

properly. Electrical seat adjustment (Y page 94) 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 95). 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 98). X Check whether steering wheel : is

adjusted properly. Adjust the steering wheel electrically (Y page 99) When adjusting the steering wheel, make sure: Ryou can hold the steering wheel with your

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. 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.
