Transporting children safelyVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
The right place for children Note Children in the vehicle
Do not leave children unattended in the
vehicle; otherwise, they could endanger them‐
selves and other persons, e.g., by opening the
doors.◀
Children should always be in the rear
Accident research shows that the safest place
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 fixing systems pro‐
vided in accordance with the age, weight and
size of the child; otherwise, there is an in‐
creased 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
fixing 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 fixing system in the front passenger
seat, make sure that the front, knee and side
airbags on the front passenger side are deacti‐vated. Automatic deactivation of front passen‐
ger side airbags, refer to page 93.
Note Deactivated front passenger airbags
If a child restraint fixing system is used in
the front passenger seat, the front passenger
airbags must be deactivated; otherwise, there
is an increased risk of injury to the child when
the airbags are triggered, even with a child re‐
straint fixing system.◀
Installing child restraint
fixing systems
Hints Manufacturer's information for child re‐
straint fixing systems
To select, mount and use child restraint fixing
systems, observe the information provided by
the system manufacturer; otherwise, the pro‐
tective effect can be impaired.◀
Lock the rear seat backrests in position
Before installing a child restraint system,
make sure that the rear seat backrests are
locked; otherwise, the protective effect is not
guaranteed and there is an increased risk of in‐
jury for the child in the event of an accident.◀
On the front passenger seat
Deactivating airbags
After installing a child restraint fixing system in
the front passenger seat, make sure that the
front, knee and side airbags on the front pas‐
