Cadillac 2004 XLR Owner's Manual page 36

Unless the passenger's air bags have been turned off,
never put a rear-facing child restraint in this vehicle.
Here is why:
{
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the 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. Do not use a
rear-facing child restraint in this vehicle unless
the passenger's air bag has been turned off.
Even though the AIR BAG OFF switch is
designed to turn off the passenger's air bags
under certain conditions, 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. We,
therefore, recommend that rear-facing child
restraints be transported in vehicles with a
rear seat that will accommodate a rear-facing
child restraint, whenever possible.

CAUTION: (Continued)
CAUTION: (Continued)
If you secure a forward-facing child restraint
in the passenger seat, always move the
passenger seat as far back as it will go.
{
CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bags, it
means that something may be wrong with the
air bag system. The passenger's air bags
could inflate even though the switch is off. If
this ever happens, do not let anyone whom
the national government has identified as a
member of a passenger air bag risk group sit
in the passenger's position (for example, do
not secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
