Chevrolet 2006 HHR Owner's Manual page 61

If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, never put a
child in a rear-facing child restraint in the right front
passenger seat unless the passenger airbag status
indicator shows off. Never put a rear facing child
restraint in the right front passenger seat unless the
airbag 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 airbag inflates. This is because the
back of the rear facing child restraint would be
very close to the inflating airbag. Be sure the
airbag is off before using a rear-facing child
restraint in the passenger's position.
Even though the passenger sensing system is
designed to turn off the passenger's frontal
airbag and side impact airbag (if equipped) if
the system detects a rear-facing child restraint,
CAUTION: (Continued)
CAUTION: (Continued)
no system is fail-safe, and no one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though it is
turned off. We recommend that rear-facing
child restraints be transported in vehicles with
a rear seat that will accommodate a rear-facing
child restraint, whenever possible.
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 the forward-facing child
restraint. See Manual Seats on page 1-2.
If your child restraint is equipped with the LATCH
system, see Lower Anchors and Tethers for Children
(LATCH) on page 1-45.
