GMC 2007 Envoy - Manual (Page 462)

Accessory Inflator
Your vehicle may have an accessory inflator
system. You can inflate 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 inflate large objects which will require
more than five minutes to inflate, such as an air
mattress.
The accessory inflator
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 inflator.
You may have an air inflator 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 inflator, do the following:
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.
