Never put a rear facing child restraint in the right front
passenger's seat unless the air bag is off. Here is why:
{
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because
the back of the rear-facing child restraint
would be very close to the inflating air bag.
Be sure the air bag is off before using a
rear-facing child restraint in the right front seat
position. If you secure a forward-facing child
restraint in the right front seat, always move
the right front passenger seat as far back as it
will go.
A rear seat is a safer place to secure a forward facing
child restraint. See Where to Put the Restraint on
page 1-39 . If you need to secure a forward-facing child
restraint in the right front seat position, move the
seat as far back as it will go before securing a
forward-facing child restraint. See Power Seats on
page 1-3 .

CAUTION:
If the air bag readiness light in the instrument
panel cluster ever comes on when you have
turned off the air bag, it means that something
may be wrong with the air bag system. The
right front passenger's air bag could inflate
even though the switch is off. If this ever
happens, have the vehicle serviced promptly.
Until you have the vehicle serviced, do not let
anyone whom the national government has
identified as a member of a passenger air bag
risk group sit in the right front passenger's
position (for example, do not secure a
rear-facing child restraint in the right front
passenger's seat). See "Air Bag Off Switch" in
the Index.
