Other Warning Devices
If you carry reflective triangles, you can use them to
warn others. Set
one up at the side of the road about
300 feet (100 m) behind your vehicle.
Jump Starting
If your battery has run down, you may want to use another
Iehicle and some jumper cables to
start your vehicle. But
)lease use the following steps listed
to do it safely.
A CAUTJON:
-
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to burn you.
If you don’t follow these steps exactly, some or all
of these things can hurt you.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered by
your warranty.
Trying to start your vehicle by pushing or pulling
it won’t work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with
a negative ground system.
NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.
If you have a diesel engine vehicle with two batteries
(or more) you should know before you begin that,
especially in cold weather, you may not be able to
get enough power from a single battery
in another
vehicle to start your diesel engine.

Towing Your Vehicle
Try to have your GM dealer or a professional towing
service tow your vehicle. They can provide the right
equipment and know how to tow it without damage. See
“Roadside Assistance” in your 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 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.
0 , The make, model and year of your vehicle.
0 Whether you can move the shift lever for

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 little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 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
-- DRIVE (D).
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, you can idle the engine
for two or three minutes while you’re parked,
to 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 ofthe engine and get everyone out qf the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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 you could be burned.
Get any leak fixed before you drive the vehicle.
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.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a 5060 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 sy,,,m
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.

Downloaded from www.Manualslib.com manuals search engine I 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.
A CAIJTION:
-
You can be b ed 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 the
FULL 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 If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what
to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from
the
accelerator pedal. Get the vehicle under control by
steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake
to a stop -- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment
to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn
on your hazard
warning flashers.
I
Changing a tire can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire.
To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. ”urn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear
of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.

See if any one of these is true for you:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.

If done of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did YOU know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water,
or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be
a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it
on the ground, into
sewers, or into streams
or bodies of water. Instead,
recycle it by taking
it to a place that collects used oil. If
you have a problem properly disposing
of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle for 5 years or 100,000 miles ( 166 000 km),
whichever occurs first.
The following explains your cooling system and how
to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
A 5060 mixture of water and the proper coolant for
your vehicle will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129 O C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine coolant
will require change sooner -- at
