overheating OLDSMOBILE AURORA 2002 Owners Manual

2-76 Traction Control System Active Light
(If Equipped)
United States Canada
When your traction control system is limiting wheel
spin, this light will come on. Slippery road conditions
may exist if the traction control system active light
comes on, so adjust your driving accordingly.
The light will stay on for a few seconds after the traction
control system stops limiting wheel spin.
Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the shaded warning zone, your
engine is hot.
To prevent engine overheating, the air conditioning
compressor will turn off automatically, a fast
-pulsed
chime will sound, and the message ENGINE HOT...A/C
OFF will appear in the Driver Information Center (DIC).
As the engine cools down, the air conditioning
compressor will automatically turn back on.

2-77
If the coolant temperature is over 262
F (128
C), the
message HOT...IDLE ENGINE will appear. It means
you should reduce the engine load and speed to prevent
the engine from overheating.
If the coolant temperature is over 268
F (131
C), the
message HOT...STOP ENGINE will appear. It means
that your engine coolant has overheated. You should pull
off the road, stop your vehicle and turn off the engine as
soon as possible.
Your vehicle is equipped with an Overheated Engine
Protection Operating Mode. See ªEngine Overheatingº
in the Index for more information.
If your coolant level is low, the message LOW ENGINE
COOLANT will appear on the Driver Information
Center. Check your coolant level as soon as possible.

Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.

4-40 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

start your engine,

shift into a gear, and

release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you find them quickly. If you're trailering, it's
a good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

Towing Your Vehicle
Consult your dealer or a professional towing service
if you need to have your disabled vehicle towed. See
ªRoadside Assistanceº in the Index. If you want to
tow your vehicle behind another vehicle for recreational
purposes (such as behind a motorhome), see
ªRecreational Vehicle Towingº in the Index.
Engine Overheating
You will find a coolant temperature gage on your
vehicle's instrument panel. Your Driver Information
Center (DIC) will also display messages about engine
overheating. See ªEngine Coolant Temperature Gageº
in the Index.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
message HOT STOP ENGINE is displayed, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this mode,
you will notice a loss in power and engine performance.
This operating mode allows your vehicle to be driven
to a safe place in an emergency. Driving extended
miles (km) and/or towing a trailer in the overheat
protection mode should be avoided.
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 will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

5-14
A low coolant level should be indicated by a LOW
ENGINE COOLANT message on the Driver
Information Center. If it is, you may have a leak at
the pressure cap or in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
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.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren't, your vehicle needs service.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
See ªOverheated Engine Protection Operating
Modeº in the Index.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL
is not
covered by your new vehicle warranty.

Engine Coolant
The cooling system in your vehicle is filled with
DEX
-COOL
engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX
-COOL
extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see ªEngine Overheatingº
in the Index.
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

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
only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to the

Cooling System Pressure Cap
The cooling system pressure cap is located on the
surge tank.
NOTICE:
Your cooling system pressure cap is a 18 psi
(124 kPa) pressure
-type cap and must be tightly
installed to prevent coolant loss and possible
engine damage from overheating.
Power Steering Fluid
The power steering fluid
reservoir is near the center
of the engine compartment
on the passenger's side of
the vehicle. See ªEngine
Compartment Overviewº in
the Index for more
information on location.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service, see
your Oldsmobile Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.
CAUTION: (Continued)
CAUTION: (Continued)

Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.

Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.

Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
