Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a
hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your
parking brake, and then shift to
PARK (P) for an
automatic transmission, or
REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on
this. Things that are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, drive belts, cooling
system and brake adjustment. Each of these is covered
in
this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review
this information before you start your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions may not be correct.
Before
you do anything, turn on the hazard
warning flashers.
When
you call, tell the towing service:

That your vehicle cannot be towed from the front or
rear with sling-type equipment.
That your vehicle has rear-wheel drive.
The make, model and year of your vehicle.
Whether
you can still move the shift lever.
If there was
an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want
to see them.

I A CAUTION:
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components. When your vehicle is being towed, have the ignition
key turned to the
OFF position.
The steering wheel
should be clamped in a straight-ahead position, with
a clamping device designed for towing service.
Do not
use the vehicle’s steering column lock for this. The
transmission should be in NEUTRAL
(N) and the
parking brake released.
Don’t have your vehicle towed on the drive wheels
unless you must.
If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later in this section or your transmission will
be damaged.
If these limits must be exceeded, then the
drive wheels have to be supported on a dolly.

I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as
well as the tires. If you spin the wheels
too fast while shifting your transmission back and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
~ Rocking Your Vehicle To Get It Out
~ First, turn your steering wheel left and right. That will
clear
the area around your front wheels. If your vehicle
has traction control, you should turn the system
off.
(See “Traction Control System’’ in the Index.) Then shift
back and
forth between REVERSE (R) and a forward
gear (or with a manual transmission, between
FIRST (1)
or SECOND (2) and REVERSE (R)), spinning the
wheels as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transmission
is in gear. If that doesn’t
get
you out after a few tries, you may need to be towed
out. If you do need to be towed out, see “Towing Your
Vehicle” in the Index.
