Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are inclu-
ded with the child restraint system.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.
Child restraint system on the front-
passenger seat
General notes
If you secure a child in a child restraint system on the front-passenger seat, be sure to
observe the instructions and safety notes on
the "Occupant Classification System (OCS)"( Y page 49).
You can thus avoid the risks that could arise
as a result of:
R an incorrectly categorized person in the
front-passenger seat
R the unintentional deactivation of the front-
passenger front air bag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facing child restraint system
If it is absolutely necessary to install a rear-
ward-facing child restraint system on the
front-passenger seat, always make sure that
the front-passenger front air bag is deactiva-
ted. Only if the PASSENGER AIR BAG OFF
indicator lamp is permanently lit ( Ypage 41)
is the front-passenger front air bag deactiva-
ted.
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Forward-facing child restraint system
If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
always move the front-passenger seat as far
back as possible. The entire base of the child
restraint system must always rest on the seat cushion of the front-passenger seat. The
backrest of the child restraint system must lie as flat as possible against the backrest of the
front-passenger seat. The child restraint sys-
tem must not touch the roof or be subjected
to a load by the head restraint. Adjust the
angle of the seat backrest and the head
restraint position accordingly. Always make
sure that the shoulder belt strap is correctly
routed from the front-passenger seat belt
loop to the shoulder belt guide on the child
restraint system. The shoulder belt strap
must be routed forwards and downwards
from the front-passenger seat belt loop.
Always observe the child restraint system
manufacturer's installation and operating
instructions.
Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured in the vehicle, they could press buttons or
switches, for example.
As a result, they could: R activate vehicle equipment and become
trapped, for example
R activate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud- den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
