for children is in the back seat.
Transporting children in the rear
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; otherwise, there is an increased risk
of injury in an accident.
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.

ger airbags, refer to page  103.Note
Deactivating the front-seat passenger
airbags
If a child restraint system is used in the front
passenger seat, deactivate the front-seat pas‐
senger airbags; otherwise, there is an in‐
creased risk of injury to the child when the air‐
bags are activated, even with a child restraint
system.◀

tive effect can be lost.◀
Ensuring the stability of the child seat
When installing child restraint systems,
make sure that the child seat is securely fas‐
tened to the backrest of the seat. Angle and
headrest of the backrest might need to be ad‐
justed or possibly be removed. Make sure that
all backrests are securely locked. Otherwise
the stability of the child seat can be affected,
and there is an increased risk of injury becauseSeite 60ControlsTransporting children safely60

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.
