2009 GMC ACADIA battery

A wet seat can affect the
performance of the passenger
sensing system. Here is how:
The passenger sensing system
may turn off the passenger airbag
when liquid is soaked into the
seat. If this happens, the off
indicator will be lit, and the airbag
readiness light on the instrument
panel will also be lit.
Liquid pooled on the seat that has
not soaked in may make it more
likely that the passenger sensing
system will enable (turn on) the
passenger airbag while a child
restraint or child occupant is on
the seat. If the passenger airbag
is turned on, the on indicator
will be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. SeeAirbag
Readiness Light on page 3-36for
important safety information.
{CAUTION
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing Your
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the vehicle and the airbag
system. To purchase a service
manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inate during improper
service. You can be injured if you
are close to an airbag when it
inates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualied to do so.
