2007 GMC ENVOY tires

Accessory Inator
Your vehicle may have an accessory inator
system. You can inate things like basketballs and
bicycle tires. You can also use it to bring your
tire pressure up to the proper pressure. It is not
designed to inate large objects which will require
more than ve minutes to inate, such as an air
mattress.
The accessory inator
is located in the rear
compartment on
the driver’s side of the
vehicle behind an
access cover, near
the liftgate opening.To remove the cover, push in on the tab to access
the inator.
You may have an air inator kit that is located in
the glove compartment. It includes a 22 ft (6.7 m)
hose with three nozzle adapters.
To use the accessory inator, do the following:
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.

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 will create 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.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal.
Get the vehicle under control by steering the
way you want the vehicle to go. It may be very
bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to
use the jacking equipment to change a at
tire safely.

Spare Tire
Your vehicle, when new, had a fully-inated spare
tire. A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire
Pressure on page 447andLoading Your Vehicle
on page 349for information regarding proper tire
ination and loading your vehicle. For instruction on
how to remove, install or store a spare tire, see
Removing the Flat Tire and Installing the Spare Tire
on page 469andStoring a Flat or Spare Tire and
Tools on page 478.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available
in case you need it again.
Do not mix tires and wheels of different sizes,
because they will not t. Keep your spare tire
and its wheel together.

Aluminum Wheels
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
The surface of these wheels is similar to the
painted surface of the vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because the surface could
be damaged. Do not use chrome polish on
aluminum wheels.Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels. The
repairs would not be covered by your warranty.
Never drive a vehicle equipped with aluminum
or chrome-plated wheels through an
automatic car wash that uses silicone carbide
tire cleaning brushes.
Do not take the vehicle through an automatic car
wash that has silicone carbide tire cleaning
brushes. These brushes can also damage the
surface of these wheels.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
