Hazard Warning Flashers
AN505005
Your hazard warning flashers let you warn others. They also let police know
you have a problem. Your front and rear turn signal lights flash on and off.
But they won't flash if you are braking.
F

K2503
Press the button in to make your front and rear turn signal lights 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, pull out on the collar.
When the hazard warning flashers are
on, your turn signals won't work.
Other Warning Devices
If you carry reflective triangles, you can set one up at the sid\
e 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 follow the ste\
ps below to
do it
safely.
I CAUTION
Batteries can hurt you. They can be dangerous because:
They contain
add that can burn you.
e 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

To Jump Start Your Vehicle
1. Check the other vehicle. It must have a 12-volt battery with a negative
ground system.
NOTICE
m with a negative ground, both ..
2. Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren't touching each other.
If they are, it could cause a
5-3

ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical systems.
CAUTION
A You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in
P (Park) or a
manual transmission in
N (Neutral).
If you have a four-wheel-drive vehicle, be sure the transfer case is
not in N (Neutral).
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!
I
I jou leave a radio on, it could be badly damaged. The repairs woulc
be covered by your warranty.
4. Open the hoods and locate the batteries.
Find the positive
(t) and negative (-) terminals on each battery,
CAUTION
A Using a match near a battery can cause battery gas to explode.
b People have been hurt doing this, and some have been blinded. \
Use
a flashlight if you need more light.
Be sure the batteries have enough water.
You don’t need to add
water
to the Delco Freedom@ battery installed in every new GM
vehicle. But if a battery has filler caps, be sure the right amount of
fluid
is there. If it is low, add water to take care of that first. If you
don’t, explosive gas could be present.
Battery fluid contains acid that can bum you. Don’t get
it on you. If’
you accidentally get it in your eyes or on your skin, flush the place
with water and get medical help immediately. c
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 things you should\
know.
Positive (t) will go to positive (t) and negative (-) will go to negative

(-) or a metal engine part. Don’t connect (t) to (-) or you’ll get a
short that would damage the battery and maybe other parts, too.
A Fans or other moving engine parts can injure you badly. Keep your
h hands away from moving parts once the engines are running.
6. Connect the red positive (t) cable to the positive (t) terminal of the
vehicle with the dead battery. Use a remote positive
(+) terminal if the
vehicle has one.

7. Don’t let the other end touch metal. Connect it to the positive (+)
terminal of the good battery. Use a remote positive (+) terminal if the
vehicle has one.
8.
Now connect the black negative (-) cable to the good battery’s negative
(-) terminal.
Don’t let the other end touch anything until the next step. The other end
of the negative cable
doesn’t go to the dead battery. It goes to a heavy
unpainted metal part on the engine
of the vehicle with the dead battery.
9. Attach the cable at least 18 inches (45 cm) away from the dead battery,
but not near engine
parts that move. The electrical connection is just as
good there, but the chance
of sparks getting back to the battery is much
less.

Tiwing Your Vehicle
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:
That your vehicle has rear-wheel drive, or that it has the four-wheel drive
option.
The make, model, and year of your vehicle.
Whether you can move the shift lever for the transmission and \
transfer
If there was an accident, what was damaged.
case,
if you have one.
CAUTION I
To help avoid
injury to you or others:
A 9 Never let passengers ride in a vehicle that is being towed.
e Never tow faster than safe or posted speeds.
e Never tow with damaged parts not fully secured.
Never get under your vehicle after it has been lifted by the tow
truck.
* Always use separate safety chains on each side when towing a
vehicle.
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 and transfer case,
if you have one, should be in
Neutral and the parking brake released.
If you have a two-wheel drive vehicle, don’t have your vehicle \
towed on the
rear wheels, unless you must.
If the vehicle must be towed on the rear
wheels, don’t
go more than 35 mph (56 kmlh) 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.

Pmbkms on the Road
If your vehicle has the four-wheel-drive option and the transfer case is
engaged,
a dolly must be used under the rear wheels when towing from the
front.
Engine Overheating
You will find a coolant temperature gage on your vehicle instrument panel,
If Steam Is Coming From Your Engine:

‘i Steam from an overheated engine can bum 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 vehide until it cools down. Wait until there is no sign of steam or
coalant 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

If No Steam Is Coming From Your C gine:
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.
Tow a trailer.
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.
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten 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.
