CAUTION:
If the air bag ON indicator comes on when you
have a rear-facing child restraint installed in
the right front passenger's seat, it means that
the passenger sensing system has not turned
off the passenger's frontal air bag. 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. Don't use a
rear-facing child restraint in the right front
passenger's seat unless the air bag is off.
To remove the child restraint, unhook the top tether
from the top tether anchorage and then disconnect the
LATCH attachments from LATCH anchorages.

If you had turned the air bag off with the switch,
remember to be sure to use the air bag off switch to
turn on the right front passenger's air bag when
you remove the child restraint from the vehicle unless
the person who will be sitting there is a member of
a passenger air bag risk group. See Air Bag Off Switch
on page 1-68 .
{
CAUTION:
If the right front passenger's air bag is turned
off for a person who isn't in a risk group
identified by the national government, that
person won't have the extra protection of an
air bag. In a crash, the air bag wouldn't be able
to inflate and help protect the person sitting
there. Don't turn off the passenger's air bag
unless the person sitting there is in a risk
group. See "Air Bag Off Switch" in the Index
for more on this, including important safety
information.
