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. <
The rear center seat is not suitable for installing
child-restraint systems for all age groups,
approved for the age group in question.
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child-restraint systems
appropriate for their age, weight and size. Oth-
erwise there is an increase d risk of injury in the
event of an accident. <
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.
Exception for front passenger seat
Should it be necessa ry to use a child-
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactiva ted. Otherwise, a child
traveling on that seat w ill face a significant risk
of injury if the airbags are triggered off, even
with a child-restraint system. <
For more information on automatic deactivation
of the front passenger airbags refer to page 88.
Installing child-restraint
systems
Observe the child-restraint system man-
ufacturer's instructio ns when selecting,
installing and using child -restraint systems.
Otherwise the protective effect may be dimin-
ished. < Standard child-restraint systems are designed
to be secured with a lap be
lt 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 front passenger seat
After installing a child-restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated, ot herwise there is an
increased risk of injury if the airbags deploy. <
Backrest width*
The backrest width of the front passen-
ger's seat must be at its widest possible
setting. Do not change the setting after install-
ing the child seat. Othe rwise the child seat's
stability on the front passenger's seat is lim-
ited. <
1. Adjust the backrest width to its widest set-
ting, refer to page 43.
2. Install the child seat.
Child seat security
The rear safety belts and the front passenger's
safety belt can be prevented from being pulled
out in order to fasten child-restraint systems.

system
LATCH: Lower Anchors and Tethers for CHil-
dren.
To install and use the LATCH child
restraint system, follow the operating and
safety instructions pr ovided by the manufac-
turer of the system, otherwise the protective
function of the seat may be compromised. <
Before installing the child seat, pull the belt out
of the area for the child-restraint fixing system.
Ensure that both lower LATCH anchors
are correctly engaged and that the child
restraint system is resting firmly against the
backrest, otherwise the pr otective function of
the seat may be compromised. <
Rear seats with through-loading
system
The anchor points for the lower LATCH
anchors are located behind the labeled protec-
tive caps.
Rear seats without through-loading
system
The anchor points for the lower LATCH
anchors are located at the positions indicated
