9. 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.
10.
11.
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.
Now start the vehicle with the good battery and run
the engine for a while.

12. Try to start the vehicle with the dead battery. If
it won’t start after a few tries, it probably needs
service.
13. 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 dealer or a professional towing
service tow your vehicle.
If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service:
That your vehicle can only be towed from the front
0 That your vehicle has front-wheel drive.
0 The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains detailed towing
instructions and illustrations. The operator may want to
see them. with
sling type equipment.

You will find a coolant temperature gage on your
Aurora’s instrument panel.
Your information center will
also display messages about engine overheating. See
“Coolant Temperature Gage” in the Index.
Overheated Engine Protection Operating
Mode
Should a low coolant condition exist and the message
HOT STOP ENGINE is displayed, an overheat
protection mode which alternates firing groups of four
cylinders helps prevent engine damage. This operating
mode allows your vehicle to be driven to a safe place in
an emergency; you may drive up to
50 miles (80 km).
Towing a trailer in the overheat protection mode should
be avoided.
Y
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine
to cool before attempting any repair.
The engine oil may be severely degraded. Change
the oil and reset the oil life indicator. See “Engine
Oil, When to Change” in the Index.

lP Steam Is Coming From Your Engine
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. See “Overheated
Engine Protection Operating Mode’’ in the Index.
ProCarManuals.com

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.
0 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. 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 (0)
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, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then, if you still have the
warning,
turn ofSthe engine and get everyone out of the
vehicle
until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.
ProCarManuals.com

When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Surge Tank with Pressure Cap
B. Two Electric Engine Cooling Fans
An 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 surge tank is boiling,
don’t do anything else until it cools down.
ProCarManuals.com

The coolant level should be indicated by a CHECK
COOLANT
LEVEL message on the Driver Information
Center.
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 C,’ UT’O’‘:
~ 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.
I NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan(s) are running. If the engine
is overheating, both fan(s) should be running.
If they
aren’t, your vehicle needs service.

How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at FULL COLD, add a
50/50 mixture of clean
water (preferably distilled) and DEX-COOL TM
antifreeze at the coolant surge tank, but be sure the
cooling system, including the coolant surge tank
pressure cap, is cool before you do
it. (See “Engine
Coolant” in the Index for more information.)
I
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 coolant surge
tank pressure cap
-- even a little -- they can come
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap, is hot. Wait for the cooling system
and coolant surge tank pressure cap to cool if you
ever have to turn the pressure cap.
3-1Y
ProCarManuals.com

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.
ProCarManuals.com

I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
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.
1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose,
is no
longer hot.
Turn the pressure cap slowly about
one-quarter
turn to the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
