Chevrolet 2005 Express Van Owner's Manual page 62

Unless your vehicle has an airbag off switch and you
have used it to turn the passenger's airbag off, never put
a rear-facing child restraint in the right front passenger's
seat. 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. If your vehicle
is a passenger van, always secure a rear-facing
child restraint in a rear seat. If your vehicle is a
cargo van with a right front passenger airbag
and an airbag off switch, be sure to turn off the
airbag before using a rear-facing child restraint
in the right front seat position. If your vehicle is
a cargo van with a right front passenger airbag
but does not have an airbag off switch, do not
use a rear-facing child restraint in this vehicle.

CAUTION: (Continued)
CAUTION: (Continued)
Even though the airbag off switch is designed
to turn off the passenger's frontal airbag, 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. GM recommends 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 passenger position,
always move the passenger seat as far back as
it will go.
A rear seat is a safer place to secure a forward-facing
child restraint. See Where to Put the Restraint on
page 1-42.
