( Y page 60).
GWarning
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position shoulder belt across the chest and
shoulder, not face or neck.
In order to attain the correct seating position
for children weighing over 41 lb (18 kg), it may
be necessary to use a booster seat until they
reach a height where a normal lap/shoulder
seat belt lies properly across their bodies
without the need for a booster seat.
Install the child restraint system according to
the manufacturer's instructions.
The child restraint system must be installed
firmly on both brackets.
An incorrectly installed child restraint system
can come loose in the event of an accident,
causing the child to be severely or fatally
injured.
Child restraint systems/child restraint
retaining brackets that are damaged or have
suffered damage due to an impact must be
replaced.
ISOFIX is a standardized securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two LATCH-
type (ISOFIX) child restraint systems are
installed on the left and right of the rear seats.
Use the vehicle's seat belts to install child
restraint systems without the ISOFIX
securing system. Follow the manufacturer's
instructions for of child restraint systems.
! Vehicles with a center seat in the rear:
when installing the LATCH-type (ISOFIX)
child restraint system, make sure that the

Sliding sunroof
Important safety notes
Your vehicle may be installed with a sliding
sunroof or a panorama roof with power tilt/
sliding panel. In the following section, the
term "sliding sunroof" refers to both types of
sliding sunroof.
GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, 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. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following 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 the child could be burned by these
parts.
GWarning
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:
R strong braking maneuvers
R sudden changes of direction
R an accidentGWarning
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. If the movement of the sliding sunroof
is blocked during the closing procedure, the
sliding sunroof will stop and open slightly.
The sliding sunroof operates differently when
the sliding sunroof switch is pressed and held.
See the "Problems with the sliding sunroof/
panorama roof with power tilt/sliding panel"
section for more details.
The opening/closing procedure of the sliding
sunroof can be immediately halted by

event of an accident, the glass may shatter.
This may result in an opening in the roof.
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.

Important safety notes
GWarning
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.
GWarning
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.
GWarning
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.GWarning
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.
GWarning!
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.
GWarning
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.
