Latch GMC ENVOY 2008 User Guide

If your child restraint has the LATCH system, seeLower
Anchors and Tethers for Children (LATCH) on page 1-41
for how to install your child restraint using LATCH. If you
secure a child restraint using a safety belt and it uses a
top tether, seeLower Anchors and Tethers for Children
(LATCH) on page 1-41for top tether anchor locations.
Do not secure a child seat in a position without a top
tether anchor if a national or local law requires that the
top tether be anchored, or if the instructions that come
with the child restraint say that the top strap must be
anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions
that came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
When the passenger sensing system has turned off
the right front passenger’s frontal airbag, the off
indicator on the passenger airbag status indicator
should light and stay lit when you start the vehicle.
SeePassenger Airbag Status Indicator on
page 3-34.
2. Put the child restraint on the seat.3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
4. Push the latch plate into the buckle until it clicks.
Make sure the release button is positioned so you
would be able to unbuckle the safety belt quickly
if necessary.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly.
Look for any other loose or damaged safety belt system
parts. If you see anything that might keep a safety belt
system from doing its job, 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 3-32for more
information.
Keep safety belts clean and dry. SeeCare of Safety
Belts on page 5-103.
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 3-33for 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 1-59.
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 you have had a crash, do you need new belts or
LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the belt assemblies that were used during any crash
may have been stressed or damaged. See your dealer/
retailer to have your safety belt assemblies inspected or
replaced.
If your 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
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 your safety belt pretensioners checked if your
vehicle has been in a crash, if your airbag readiness
light stays on after you start your vehicle, or while you
are driving. SeeAirbag Readiness Light on page 3-33.

To use the accessory inator:
1. Attach the appropriate nozzle adapter to the end of
the hose, if required.
{CAUTION:
Inating something too much can make it
explode, and you or others could be injured.
Be sure to read the inator instructions, and
inate any object only to its recommended
pressure.
2. Attach that end of the hose to the object you wish
to inate.
3. Attach the other end of the hose to the outlet.
4. Press and release the switch to turn the air inator
on. The indicator light will remain on when the
inator is running.
The system has an internal clock to prevent the
system from overheating. The system will allow
about ve minutes of running time, then the
compressor will stop. The indicator light will then
begin to ash. When the indicator is off, the inator
can be started again by pressing the switch. If the
compressor is still hot, it may only run for a short time
before shutting off again.
5. Press and release the switch to turn the inator off.Place the inator kit tools in the pouch and store it in
its proper location. Remove the inator hose from
the outlet during loading and unloading. Load leveling
will not function with the inator hose attached to
the inator outlet. SeeElectronically Controlled Air
Suspension System on page 4-44for more information.
To reinstall the cover, line up the tabs at the back of
the cover, put it in place and latch the tabs.
A continuous ashing indicator light may also indicate a
malfunction in the air suspension system. See
Electronically Controlled Air Suspension System on
page 4-44for more information.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle’s tires properly.
If air goes out of a tire, it is much more likely to leak out
slowly. But if you should ever have a blowout, here
are a few tips about what to expect and what to do:
If a front tire fails, the at tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and then gently brake
to a stop well out of the traffic lane.
