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.

or infant carriers on the front passenger
seat - even with an Advanced Airbag System.
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,

PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system

liquids on the front passenger seat cushion.
- Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats) . These may influence the electrical
capacitance measured by the capacitive pas­
senger detection system and can also fly
around in an accident and cause serious per­
sonal injury.
