Your vehicle has a right front passenger air bag.
Although a rear seat is a safer place, you can secure a
forward-facing child restraint in the right front seat.
Unless your vehicle has the passenger sensing system,
Never put a rear-facing child restraint in this seat.
Here's 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.
Always secure a rear-facing child restraint in a
rear seat unless the air bag is off.
If your vehicle has the passenger sensing system and
you need to secure a rear-facing child restraint in
the right front passenger's seat, the passenger's air bag
must be off. See Passenger Sensing System on
page 1-81 and Passenger Air Bag Status Indicator on
page 3-40 for more information on this including
important safety information.

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.
Even though the passenger sensing system is
designed to turn off the passenger's frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag will not deploy
under some unusual circumstance, even
though it is turned off. General Motors
therefore recommends that rear-facing child
restraints be secured in the rear seat whenever
possible, even if the air bag is off.
If your child restraint is equipped with the LATCH
system, see Lower Anchorages and Top Tethers for
Children (LATCH System) on page 1-59 . See Top Strap
on page 1-54 if the child restraint has one.
