Child safety
-The child and the passenger can also in­
jure each other in an accident.
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates -even with an Advanced Airbag Sys­
tem.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
- Always install rear-facing child safety seats
or infant carriers on the rear seat.
- Make sure there is enough space in front of
the child in the child seat. If necessary, ad­
just the angle and position of the seat in
front of the child seat.
- Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child. Always install for­
ward-facing child safety seats on the rear
seat.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety
and well-being require that the following
special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its manu­
facturer for use on a front seat with a pas­
senger front and side airbag.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Always move the front passenger seat to the highest position in the up and down
adjustment range and move it back to the rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing child restraint.
- Always make sure that the safety belt up­
per anchorage is behind the child restraint
and not next to or in front of the child
re-
300
straint so that the safety belt will be prop­
erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from being moved to the rearmost position in its fore
and aft adjustment range.
-Always make sure that the backrest is in
the upright position.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat­
er for child seats) on the front passenger seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de­
vice, power inverter or seat heater for
child seats). These may influence the elec­
trical capacitance measured by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision .
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used<::;>

The airbag on the passenger side makes the front
seat a potentially dangerous place for a child to ride. The front seat is not the safest place for a
child in a forward-facing child seat. It is a very
dangerous place for an infant or a larger child in
a rearward-facing seat .
A WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
child restraint increases the risk of serious
personal injury and death in a crash.
- Never install rear -facing child safety seats
or infant carriers on the front passenger

tem . A child will be seriously injured and can
be killed when the inflating airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and child against the backrest, center armrest,
door or
roof <=> page 2 72, Child restraints on
the front seat -some important things to
know .
-Always install rear-facing child safety seats
or infant carriers on the rear seat.
- Never install a rear-facing child restraint in the forward-facing direction. Such restraints
are designed for the special needs of infants and very small children and cannot protect
them properly if the seat is forward-facing .
- If you must install a rearward facing child safety seat on the front passenger seat be­cause of exceptional circumstances and the
PASSENGER AIR BAG OFF~; light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear

Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats.
The safety belts for the rear seats and for the
front passenger's seat have a convertible locking
retractor for child safety seats. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving . A child
safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all children, especially those 12 years and younger,
should always ride in the back seat properly re-
strained for their age and size.
