Towing Your Vehicle
Try to have your GM dealer or a professional towing
service tow your vehicle. See “Roadside Assistance” in
the Index. 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 such things as 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:
0 That your vehicle has rear-wheel drive, or that it has
The make, model and year of your vehicle.

know that this manual contains these towing
instructions. The operator may want to

- I
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.
When your vehicle is being towed, have the ignition key
in 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
and transfer case, if
you have one, 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 limitations must be exceeded, then
the drive wheels have
to be supported on a dolly.

You will find a coolant temperature gage on your
vehicle’s instrument panel. If your vehicle
has a diesel
engine, see “Engine Overheating” in the Diesel
Engine Supplement.
If Steam Is Coming From Your Engine
A CAUTION:
3
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay
away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there
is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
I NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a €ittle too hot when you:
Climb a long hill on a hot day.
Stop after high-’speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” in the Index.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (a) or
DRIVE
(3) for automatic transmissions. If
you no
longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still
no sign of steam, push the accelerator until
the engine speed is about twice as fast as normal idle
speed. Bring the engine speed back to normal idle speed
after two or three minutes. Now
see if the warning stops.
But then, if you still have the warning,
turn offthe
engine
and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get service
help right away.

When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan(s)
A CAUTION: I
If your vehicle has air conditioning, the auxiliary
electric fan under the hood can start up even
when the engine
is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.

Downloaded from www.Manualslib.com manuals search engine The coolant level should be at or above the COLD mark.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
.A CAUTION: I I
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine,
it could lose all coolant. That could
cause an engine fire, and y~u could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, start the engine again. See
if the
fan speed increases when idle speed is doubled by
pushing the accelerator pedal down. If it doesn’t, your
vehicle needs service. Turn
off the engine.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above the COLD mark, add a
50/50 mixture
of clean
water (preferably distilled) and DEX-COOL”
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant”
in the Index for
more information.)
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use a
50/50 mix of clean
water and
DEX-COOL TM antifreeze.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.

Downloaded from www.Manualslib.com manuals search engine 1 A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol and it
will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at or
above the
COLD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing
you can try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before you do it.

Downloaded from www.Manualslib.com manuals search engine Steam and scalding liquids from a hot cooling
system can blow @ut and burn you badly. They
are under pressure, and if
you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap,
is hot. Wait for the cooling system and
radiator pressure cap to cool
if you ever have to
turn the pressure cap.
