If A Tire Goes Flat - GMC 2008 Envoy Denali Owner's Manual

To use the accessory inflator:
1. Attach the appropriate nozzle adapter to the end of
the hose, if required.
CAUTION:
{
Inflating something too much can make it
explode, and you or others could be injured.
Be sure to read the inflator instructions, and
inflate any object only to its recommended
pressure.
2. Attach that end of the hose to the object you wish
to inflate.
3. Attach the other end of the hose to the outlet.
4. Press and release the switch to turn the air inflator
on. The indicator light will remain on when the
inflator is running.
The system has an internal clock to prevent the
system from overheating. The system will allow
about five minutes of running time, then the
compressor will stop. The indicator light will then
begin to flash. When the indicator is off, the inflator
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 inflator off.
Place the inflator kit tools in the pouch and store it in
its proper location. Remove the inflator hose from
the outlet during loading and unloading. Load leveling
will not function with the inflator hose attached to
the inflator outlet. See Electronically Controlled Air
Suspension System on page 4-44 for 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 flashing indicator light may also indicate a
malfunction in the air suspension system. See
Electronically Controlled Air Suspension System on
page 4-44 for 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 flat tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake
to a stop well out of the traffic lane.
