1 Section 5 Problems on the Road
Here you'll filld what to do about some problems that
can occur
on the road.
Hazard Warning Flashers
Your hazard warning flashers let you warn others. They
also let police know you have a problem. Your front and
rear turn signal
lamps will flash on and off.
Press the button on top of
the steering column all the
way down
to make your
front and rear turn signal
lamps flash on and
off.
Your hazard warning flashers work no matter what
position your key is
in, and even if the key isn't in.
To turn off the flashers, press the button until the first
click and release.

When the hazard warning flashers are on, your turn
signals won’t work. The flashers will stop if you step on
the brake.
Other Warning Devices
If you carry reflective triangles, you can 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
vehicle and
some jumper cables to start your vehicle. But
please use the following steps
to do it safely.
I NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered by
your warranty.
Do not try to start your vehicle by pushing or
pulling it. This could damage your vehicle and
it won’t start that way. Batteries can hurt
you. They can be
dangerous because:
0 They contain acid that can burn you.
They contain gas that can explode or ignite.
0 They contain enough electricity to
If you don’t follow these steps exactly, some or all
of these things can hurt you.
burn
you.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
I NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.

12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.

Towing Your Vehicle
Try to have a GM retailer 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:
0 That your vehicle has all-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can move the shift lever for
the transmission.
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.

If No Steam Is Coming From Your Engine
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:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for
a minute or so:
1. Turn off your air conditioner.
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 (@) or
THIRD
(3).
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 off the
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.

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
ADD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant”
in the Index for
more information.)
I
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.
I NOTICE:
r
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.
ProCarManuals.com
Page 196 of 340
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
ADD, 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.
Steam and scalding liquids from a hot cooling
system can blow out 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.

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.
ur
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. Turn 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.

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 retailer, a service station or a local recycling
center for help.
