2009 GMC ENVOY light

When the passenger sensing system has allowed the
airbag to be enabled, the on indicator will light and stay
lit to remind you that the airbag is active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger
frontal airbag, depending upon the person’s seating
posture and body build. Everyone in the vehicle who has
outgrown child restraints should wear a safety belt
properly — whether or not there is an airbag for that
person.
{CAUTION:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 3-31
for more information, including important safety
information.
If the On Indicator is Lit for a Child
Restraint
If a child restraint has been installed and the on indicator
is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as
blankets, cushions, seat covers, seat heaters, or
seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint manufacturer and
refer toSecuring a Child Restraint in the Right Front
Seat Position on page 1-52.
5. If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, turn the
vehicle off. Then slightly recline the vehicle seatback
and adjust the seat cushion, if adjustable, to
make sure that the vehicle seatback is not pushing
the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. SeeHead Restraints
on page 1-10.
6. Restart the vehicle.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle,
and check with your dealer/retailer.

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. See
Safety Belt Reminders on page 3-30for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-106.
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 3-31for 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 1-61. 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. SeeAirbag Readiness Light on page 3-31.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.

system.
The security light is
located on the instrument
panel cluster.
To operate the system:
1. Open the door.
2. Lock the door with the power door lock switch or
the Remote Keyless Entry (RKE) transmitter. The
security light should ash.
The system will not activate if the doors are locked
with the key or manual door lock.3. Close all doors. The security light should turn off
after about 30 seconds. The alarm is not armed
until the security light turns off.

and parking lamps will ash for two minutes, and the
horn will sound for 30 seconds, then will turn off to save
the battery power.
To avoid setting off the alarm by accident:
Always lock the vehicle using the door keyafterthe
doors are closed.

with the RKE transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
When the alarm is set the power door unlock switch will
not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works. The horn
fuse may be blown. To replace the fuse, seeFuses and
Circuit Breakers on page 5-113.
If the alarm does not sound or the headlamps do not
ash, the vehicle should be serviced by your
dealer/retailer.
Passlock®(U.S. Only)
Your vehicle has the Passlock theft-deterrent system.
Passlock is a passive theft-deterrent system that enables
fuel if the ignition lock cylinder is turned with a valid key. If
a correct key is not used or the ignition lock cylinder has
been tampered with, the fuel system is disabled and the
vehicle will not start.
During normal operation, the security light will turn off
about ve seconds after the key is turned to ON/RUN.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release the key
from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the engine
off. However, your Passlock system is not working
properly and must be serviced by your dealer/retailer.
Your vehicle is not protected by Passlock at this time.
You may also want to check the fuse. SeeFuses and
Circuit Breakers on page 5-113. See your dealer/retailer
for service.
In an emergency, call the Roadside Assistance Center.
SeeRoadside Assistance Program on page 7-7.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
