Chevrolet 2007 Colorado Owner's Manual page 187

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 and the airbag is off.
Here is why:
CAUTION:
{
Even though the passenger sensing
system is designed to turn off the
passenger's frontal airbag if the system
detects a rear-facing child restraint,
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 the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger's frontal airbag is enabled
(may inflate).
CAUTION:
{
If the 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
airbag. 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. Do not use
a rear-facing child restraint in the right
front passenger's seat if the airbag is
turned on.
