The right place for children
Information
WARNING
Unattended children or animals can
move the vehicle and endanger themselves
and traffic, e.g. with the following actions:▷Pressing the Start/Stop button.▷Releasing the parking brake.▷Opening and closing of doors or windows.▷Shifting the selector lever into neutral.▷Using vehicle equipment.
There is risk of accidents or injuries. Do not
leave children or animals unattended in the ve‐
hicle. Carry remote control along when exiting
and lock the vehicle.◀
Children should always be in the rear WARNING
Persons shorter than 5 ft, 150 cm cannot
correctly fasten the safety belt without suitable
additional restraint systems. The protective ef‐
fect of the safety belts can be limited or lost
when safety belts are fastened incorrectly. An
incorrectly fastened safety belt can cause ad‐
ditional injuries, e.g. in the event of an accident
or during braking and evasive maneuvers.
There is risk of injuries or danger to life. Secure
persons shorter than 5 ft, 150 cm using suita‐
ble restraint systems.◀
Accident research shows that the safest place
for children is in the back seat.
Only transport children younger than 13 years
of age or shorter than 5 ft, 150 cm in the rear in
child restraint systems provided in accordance
with the age, weight and size of the child.
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
system can no longer be used due to their age,
weight and size.
Children on the front passenger seat
Should it ever be necessary to use a child re‐
straint system in the front passenger seat,
make sure that the front, knee and side airbags
on the front passenger side are deactivated.
Automatic deactivation of front-seat passen‐
ger airbags, refer to page 104.
Information WARNING
Active front-seat passenger airbags can
injure a child in a child restraint system when
the airbags are activated. There is risk of inju‐
ries. Make sure that the front-seat passenger
airbags are deactivated and that the PASSEN‐
GER AIRBAG OFF indicator lamp lights up.◀
WARNING
The stability of the child restraint system
is limited or compromised with incorrect seat
adjustment or improper installation of the child
seat. There is risk of injuries or danger to life.
Make sure that the child restraint system fitsSeite 64ControlsTransporting children safely64

securely against the backrest. If possible, ad‐
just the backrest tilt for all affected backrests
and correctly adjust the seats. Make sure that
seats and backrests are securely engaged. If
possible, adjust the height of the head re‐
straints or remove them.◀
Installing child restraint
systems
Before mounting Before mounting child restraint systems, en‐
sure that the rear seat backrests are locked.
Move the rear seats into the rearmost position
to facilitate assembly of the child restraint sys‐
tem.
Information Pay attention to the specifications of the child
restraint system manufacturer when selecting,
installing, and using child restraint systems.

the airbags are activated. There is risk of inju‐
ries. Make sure that the front-seat passengerairbags are deactivated and that the PASSEN‐
GER AIRBAG OFF indicator lamp lights up.◀
After installing a child restraint system in the
front passenger seat, make sure that the front,
knee and side airbags on the front passenger
side are deactivated.
Deactivate the front-seat passenger airbags
automatically, refer to page 104.
Seat position and height
Before installing a child restraint system, move
the front passenger seat as far back as possi‐
ble and adjust its height to the highest and
thus best possible position for the belt and to
offer optimal protection in the event of an acci‐
dent.
If the upper anchorage of the safety belt is lo‐
cated in front of the belt guide of the child seat,
move the passenger seat carefully forward un‐
til the best possible belt guide position is
reached.
Backrest width Adjustable backrest width: before installing a
child restraint system in the front passenger
seat, open the backrest width completely. Do
not change the backrest width again and do
not call up a memory position.

tems are not correctly engaged, the protective
effect of the LATCH child restraint fixing sys‐
tem can be limited. There is risk of injuries or
danger to life. Make sure that the lower an‐
chors are securely engaged and that the
LATCH child restraint fixing system fits se‐
curely against the backrest.◀
PositionThe corresponding symbol shows the
mounts for the lower LATCH anchors. Seats equipped with lower anchors are
marked with a pair, 2, of LATCH symbols. It is
not recommended to use the inner lower an‐
chors of standard outer LATCH positions to
fasten a child restraint system on the middle
seat. Use the vehicle seat belt instead for the
middle seat.
Before installing LATCH child
restraint systems
Pull the belt away from the area of the child re‐
straint system.

All washer nozzles are supplied from one res‐
ervoir in the engine compartment.
Fill with a mixture of windshield washer con‐
centrate and tap water and – if required – with a
washer antifreeze, according to the manufac‐
turer's recommendations.
Mix the washer fluid before adding to find the
right mixture.
Do not add windshield washer concentrate and
antifreeze undiluted and do not fill with pure
water; this could damage the wiper system.
Do not mix window washer concentrates of dif‐
ferent manufacturers because they can clog
the windshield washer nozzles.
Recommended minimum fill quantity:
