Downloaded from www.Manualslib.com manuals search engine 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 turni\
ng
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. 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.
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 into PARK (P), or REVERSE
(R) for a manual transmission.
5. 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).
6. Release the parking brake.

Downloaded from www.Manualslib.com manuals search engine You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL
(N). If you have a
four-wheel-drive vehicle with a manual transfer case shift lever, be
sure the transfer case
is not in NEUTRAL (N).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries
And it could save your radio!
NOTICE:
If you leave your radio on, it could be badly damaged. The
repair wouldn’t be covered by your warranty.
~~
4. Open both hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged too.
Before you connect the cables, here are some basic things you should
know. Positive (+) will go to positive (+) and negative (-) will go to
negative
(-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get a
short that would damage the battery and maybe other parts too.

Try to have a GM dealer or a professional towing service tow your vehicle.
They can provide the right equipment and know how
to tow it without
damage.
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 things could
be damaged during towing.
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.

Downloaded from www.Manualslib.com manuals search engine When your vehicle is being towed, have the ignition key off. 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 (either automatic or manual) should
be
in NEUTRAL (N) and the transfer case (either manual shift or electronic
shift), if you have one, should be in
2HI. The parking brake should be
released.
Don’t have your vehicle towed
on the rear wheels, unless you have to. If the
velucle must be towed
on the rear wheels, don’t go more than 35 mph (56
Mh) or farther than 50 miles (80 km) or your transmission will be
damaged. If these limits must be exceeded, then the rear drive wheels have
to be supported on a dolly.
Don’t have your vehicle towed with the wheels in contact with the ground if
it has all-wheel drive. If your vehicle has the all-wheel-drive option,
it can
only be towed with all four wheels off the ground. If the vehicle must be
towed with wheel lift equipment, then either the front or rear wheels must
be supported
on a dolly or the vehicle must be transported on a flatbed
carrier.
