Downloaded from www.Manualslib.com manuals search engine If you have an automatic transmission, you should use
DRIVE
(D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of your
transmission. Or, if
you have a manual transmission,
it’s better not to use
FIFTH (5) gear, just drive in
FOURTH
(4) gear (or, as you need to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If
you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine run while parked (preferably
on level ground)
with the automatic transmission in PARK (P) (or the
manual transmission out
of gear and the parking brake
applied) for a few minutes before turning the engine
off.
If you do get the overheat warning, see “Engine
Overheating” in the Index.
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.
2.
3.
4.
5.
6.
Apply your regular brakes, but don’t shift into
PARK
(P) yet, or into gear for a manual
transmission. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your
parking brake, and then shift into PARK (P), or
REVERSE
(R) for a manual transmission.
If
you have a four-wheel-drive vehicle with a
manual transfer case shift lever, be sure the transfer
case is
in a drive gear -- not in NEUTRAL (N).
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;
0 Shift into a gear; and
0 R.elease the parking brake.

Try to have a GM dealer or a professional towing
service tow your vehicle. See “Roadside Assistance”
in
the Index.
If your vehicle
has been changed since it was
factory-new by adding things 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:
Whether your vehicle has rear-wheel drive,
four-wheel drive or all-wheel drive.
The make, model and year of your vehicle.
Whether you can move the shift lever for the
transmission and
shift the transfer case, if you
have one.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know
that this manual contains these towing
instructions. The operator may want to see them.

First, turn your steering wheel left and right. That will
clear the area around your front wheels. If you have a
four-wheel drive vehicle, shift into 4HI. 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. Or,
you can use your recovery hooks if your vehicle has
them. If you
do need to be towed out, see “Towing Your
Vehicle” in the Index.
Using the Kecovery Hooks
Your vehicle may be equipped with recovery hooks. The
recovery hooks are provided at the front of your vehicle.
You may need to use them
if you’re stuck off-road
and need to be pulled to some place where you can
continue driving.

Refer to the Maintenance Schedule to determine how
often to check the lubricant. See “Periodic Maintenance
Inspections” in the Index.
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler plug hole.
What to Use
