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

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 111.
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.◀

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.
