2009 GMC ACADIA light

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.

Restraint System
Check
Checking the Restraint
Systems
Safety Belts
Now and then, check the safety belt
reminder light, safety belts, buckles,
latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged
safety belt system parts that might
keep a safety belt system from doing
its job. See your dealer/retailer to
have it repaired. Torn or frayed
safety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders on page 3-35for more
information.Keep safety belts clean and dry.
SeeCare of Safety Belts on
page 5-84.
Airbags
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the
airbag readiness light is working.
SeeAirbag Readiness Light
on page 3-36for more information.
Notice:If an airbag covering
is damaged, opened, or broken,
the airbag may not work properly.
Do not open or break the airbag
coverings. If there are any opened
or broken airbag covers, have
the airbag covering and/or airbag
module replaced. For the
location of the airbag modules,
seeWhat Makes an Airbag
Inflate? on page 1-53. See your
dealer/retailer for service.

Replacing Restraint
System Parts After a
Crash
{CAUTION
A crash can damage the restraint
systems in your vehicle. A
damaged restraint system may
not properly protect the person
using it, resulting in serious injury
or even death in a crash. To help
make sure your restraint systems
are working properly after a crash,
have them inspected and any
necessary replacements made as
soon as possible.If the vehicle has been in a crash,
do you need new safety belts
or LATCH system (if equipped)
parts?
After a very minor crash, nothing
may be necessary. But the
safety belt assemblies that were
used during any crash may
have been stressed or damaged.
See your dealer/retailer to have the
safety belt assemblies inspected
or replaced.
If the vehicle has the LATCH
system and it was being used during
a crash, you may need new
LATCH system parts.New parts and repairs may be
necessary even if the safety belt or
LATCH system (if equipped),
was not being used at the time of
the crash.
If an airbag inates, you will need to
replace airbag system parts. See
the part on the airbag system earlier
in this section.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, if the airbag readiness light
stays on after the vehicle is started,
or while you are driving. See
Airbag Readiness Light on
page 3-36.
