while you:
0 Start your engine;
0 Shift into a gear; and
0 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, belt, cooling system and brake adjustment.
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 these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Attach a separate
safety chain around the
outboard end of each
lower control arm.
Engine Overheating
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. 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; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I 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 indicator. See “Engine Oil, When to
Change” in the Index.

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
I A CAUTION:
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.
5-17

A CAUTION:
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@ coolant.
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.

To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Cou ;ries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).
