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:
R injure themselves on vehicle parts
R be seriously or fatally injured by extreme
heat or cold
R injure 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.

Important safety notes
G
WARNING
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could otherwise become
trapped when adjusting the seat. 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:
R adjust the seat backrest
until your arms are
slightly angled when holding the steering
wheel.
R adjust 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.
R 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.
R never 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
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.
Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident. Seats

!
To avoid damage to
the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if 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.
R clean the seat covers as recommended;
see the "Interior care" section.
R do 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.
R when 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 rear-compartment head restraints
can be removed ( Y page 88).
For more information, contact a qualified
specialist workshop.
