SmartKey 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 or cargo 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

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/ 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.

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. blankets, coats, bags, seat covers, child seats or booster seats. ! Make sure that there are no objects in the footwell or behind the seats when resetting the seats. There is a risk that the seats and/or the objects could be damaged.

! 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.

i If the front door is open, the seats can be

adjusted for up 30 minutes after the ignition has been switched off.

i The head restraints in the front and rear

seats can be removed (Y page 80).

Adjusting the head restraints Important safety notes 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 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.

Resetting the front seat head restraints It is necessary to reset the front seat head restraints after the voltage supply has been interrupted, e.g. if the battery has been completely discharged or disconnected. X Make sure that the cup holder on the center

console is folded down (Y page 197).

X Move the seat as far forward as possible

and the head restraint in as far as possible.

Rear seat head restraints Important safety notes 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. G Warning! Make sure the rear seat head restraints engage when placing them upright manually. Otherwise their protective function cannot be ensured.

The back of the head will not be supported in the event of a collision. That could cause serious or even fatal injuries. Rear seat occupants can be seriously injured or killed.
