Chevrolet 2006 Colorado Owner's Manual page 158

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 the unless 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:
{
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.
