Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children on the passenger seat
Always transport children under the age
of 13 or smaller than 5 ft/150 cm in a child
restraint system suitable for their age, weight
and size, and with the passenger airbag deacti-
vated. Otherwise, there is an increased risk of
injury in the event of an accident or if the airbags
deploy.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child restraint system that is
appropriate for their age, size and weight.
For more information on automatic deactivation
of the passenger airbags refer to page86.
Installing child restraint
systems
After installing a child restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated; otherwise, there is an increased
risk of injury if the airbags deploy.
Observe the child restraint system manufac-
turer's instructions when selecting, installing
and using child restraint systems. Otherwise,
the protective effect may be diminished.<
Standard child restraint systems are designed
to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly
or improperly installed child restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the passenger seat
After installing a child restraint system on
the passenger seat, make sure that the
front and side airbags for the passenger are
deactivated; otherwise, there is an increased
risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move
the passenger seat as far back and up
* as pos-
sible to obtain the best possible position for
the belt.
Backrest width*
The backrest width of the passenger seat
must be at its widest possible setting. Do
not change the setting after installing the child
seat. Otherwise, the child seat's stability on the
passenger seat is limited.<
1.Adjust the backrest width to its widest set-
ting, refer to page43.
2.Install the child seat.
Child seat security
The safety belt for the passenger can be locked
to prevent it from being pulled out when it is
used to secure child restraint systems.
