Doors Important safety notes G WARNING When leaving the vehicle, always remove the SmartKey from the ignition lock. Always take the SmartKey with you and lock the vehicle. Do not leave children unsupervised in the vehicle, even if they are secured in a child restraint system, and do not give them access to an unlocked vehicle. A child's unsupervised access to a vehicle could result in an accident and/or serious personal injury. They could: Rinjure themselves on vehicle parts Rbe seriously or fatally injured by extreme
heat or cold
Rinjure themselves or have an accident with
vehicle equipment that may still be in operation even after the SmartKey has been removed from the ignition, such as the seat adjustment, steering wheel adjustment or memory function.
If children open a door, they could cause severe or even fatal injury to other persons; if they get out of the vehicle, they could injure themselves when doing so or be seriously or even fatally injured by any passing traffic. Do not expose the child restraint system to direct sunlight. The child restraint system's metal parts, for example, could become very hot, and a child could be burned on these parts. G WARNING Do not carry heavy or hard objects in the passenger compartment unless they are firmly secured in place. Unsecured or improperly positioned cargo increases a child's risk of injury in the event of: Rstrong braking maneuvers Rsudden changes of direction Ran accident

G WARNING When opening or closing the door windows, make sure that there is no danger of anyone being harmed by the opening/closing procedure. The front door windows are equipped with automatic operation and the anti-entrapment feature. If in automatic mode a front door window encounters an obstruction that blocks its path, the anti-entrapment feature will stop the door window and open it slightly. The door windows operate differently when the switch is pulled. See the "Problems with door windows" section for details. The closing of the front door windows can be immediately halted by releasing the switch or, if the switch was pulled past the resistance point and released, by either pressing or pulling the respective switch. The closing of the rear side windows can be immediately halted by releasing the switch. Activate the override switch when children are riding in the back seats of the vehicle. The children may otherwise injure themselves, e.g. by becoming trapped in the door window opening. G WARNING Do not keep any part of your body up against the window pane when opening a window. The downward motion of the pane may pull that part of your body down between the window pane and the door frame and trap it there. If there is a risk of entrapment, release the switch and pull it to close the window.

Sliding sunroof
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 continue to operate the sliding sunroof after switching off the engine or removing the SmartKey from the ignition. This function remains active for five minutes or until one of the front doors is opened.
G WARNING When opening or closing the sliding sunroof, make sure that there is no danger of anyone being harmed by the opening/closing procedure. The sliding sunroof is equipped with automatic operation and the anti-entrapment feature.

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.

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/
