Chevrolet 2006 Express Van Owner's Manual page 84

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:
{
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 right front
seat position.

CAUTION: (Continued)
CAUTION: (Continued)
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 you need to secure a forward-facing child
restraint in the right front seat, always move
the front passenger seat as far back as it will
go. It is better to secure the child restraint in a
rear seat.
