Chevrolet 2007 Optra Owner's Manual page 166

If the off symbol is not lit on the passenger airbag
status indicator, it means that the right front
passenger's frontal airbag and seat-mounted side
impact airbag (if equipped) are enabled (may
inflate).
CAUTION:
{
If the off symbol in the passenger airbag
status indicator does not come 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 and side airbag (if equipped).
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger's airbag or airbags inflate.
This is because the back of the rear-facing
child restraint would be very close to the
inflating airbag or airbags. Do not use a
rear-facing child restraint in the right front
passenger's seat unless the airbag or
airbags have been turned off.
166
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, "Never put a rear-facing child seat
in the front." This is because the risk to the
rear-facing child is so great, if the airbag deploys.
CAUTION:
{
Even though the passenger sensing
system is designed to turn off the right
front passenger's frontal airbag and
seat-mounted side impact airbag
(if equipped) 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 secured in the rear
seat, even if the airbag or airbags are off.
