Air Shift Control (Automatic
Transmission)
The rear axle shift control
switch for an automatic
transmission is located in
the instrument panel
switchbank.
Press the bottom of the switch to get to the low range.
The switch indicator light will come on when the
vehicle is in low range. Press the top of the switch to
return to the high range.
The two-speed axle should be in low range when you
park the vehicle. You’ll need to engage the transmission,
even moving the vehicle a little, to be sure the axle is
in low range. Then shift into PARK (P), apply the parking
brake and shut off the engine.To shift up from low to high, press the top of the rear
axle shift control switch and press down on the
accelerator. When you shift the axle from high to low,
press the bottom of the switch, release the accelerator
and then quickly press it down again.
To operate off-road or under a heavy load, shift into low
range when the vehicle is standing still and then
operate the transmission normally.
On the highway, with the axle in low range and the
transmission in top gear, you may shift the axle to high
range by raising the switch and releasing the
accelerator momentarily. Reapply the accelerator after
you shift.
Under light load conditions, first shift the axle into the
high range with the vehicle at a standstill and then
operate the transmission normally.
Air Suspension
Your vehicle may be equipped with the Hendrickson
HAS Series single-axle air suspension which is designed
for single-axle on-highway use. The feature is available
in 19,000 lb. (8 618.3 kg), 21,000 lb. (9 525.4 kg)
and 23,000 lb. (10 432.6 kg) capacities for operations
which require extra cubic capacity and a reduced
deck height.

6. Turn the stud nut
clockwise several turns
to release the brakes.
Follow the same
procedure to release
the other brake.
7. At the repair facility, apply air pressure of at least
70 psi (480 kPa) to the brake chambers, either
from an external air supply or the vehicle’s
air system.
8. Turn the stud nut counterclockwise several turns.
Remove the stud from the chamber.
9. Replace the stud and washer and tighten the nut
into the side of the chamber.
10. Replace the rubber cap.Loading Your Vehicle
There is a GVW Rating label on your vehicle that shows
how much weight it may properly carry. It also shows
the size of your original tires and the inflation pressures
needed to obtain the gross weight capacity of your vehicle.
This is called the Gross Vehicle Weight Rating (GVWR).
The GVWR includes the weight of the vehicle, all
occupants, fuel and cargo.

Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded. If wheel nuts keep coming loose, replace
the wheel. If the wheel leaks air, replace it.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM
original equipment parts. This way, you will be sure to
have the right wheel, wheel bolts and wheel nuts
for your vehicle.
{CAUTION:
A leaking wheel could fail without warning.
A wheel designed for tubeless tires could be
leaking because it is damaged. Don’t use
an inner tube or some other thing to try to
stop the leaking. Get a new wheel or the
proper type.
{CAUTION:
Without the correct wheel, you may not be able
to stop properly, and you could have other
problems like a tire air-out. You could have a
collision. If you don’t go to your dealer to get a
new wheel, be sure you get the correct one.
Each new wheel should match the original
wheel in load-carrying capacity, ination
pressure capacity, diameter, width, offset and
mounting conguration.
Using wheels and tires with higher load-carrying limits
than the original wheels and tires doesn’t change
the GAWR or the GVWR of your vehicle. See “Loading
Your Vehicle” for more information.
Notice:The wrong wheel can cause trouble in
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance, stopping distance and tire
clearance to the body and chassis. You could also
have other problems like a tire air-out.
