Reduce speed and shift to a lower gear before you start down a long or
steep downgrade. If you don’t shift down,
you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around
45
mph (70 km/h) or less to reduce the possibility of engine and transaxle
overheating.
If your trailer weighs more than 1,000 pounds (450 Kg) and you have an
automatic transaxle with Overdrive, you may want to drive
in “3” instead
of Overdrive
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill.
If something goes wrong, your rig could start to move. People can be
injured, and both your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s bow to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until
the chocks absorb the load.
4. Reapply the regular brakes. Then shift into “P” (Park) firmly and
apply your parking brake.
5. Release the regular brakes.
When You Are Ready to Leave Afler Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
c
4. Stop and have someone pick up and store the chocks.

The driver information will display either “ENGINE COOLANT HOT
IDLE ENGINE” or “STOP ENGINE ENGINE OVERHEATING.”
If Steam Is Coming From Your Engine:
A CAUTION
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.

may have a
leak in the radiator hoses, heater hoses, radiator, water pump
or somewhere else
in the cooling system.
I
A 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, check to see if the electric engine fans are
running.
If the engine is overheating, both fans 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 or above
“FULL COLD,” add a 50/50 mixture of clean water (preferably distilled)
and a proper antifreeze at
the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information about the proper coolant
mix.)
A CAUTION
Adding only plain water to your cooling system can De
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
a proper antifreeze.

ENGINE 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 “Engine
Overheating” in the Index.
The proper coo’ It for
your Cadillac will:
Give freezing protection down to -34°F (-37’C) .
Give boiling protection up to 262 ” F (128 ” C) .
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably distilled) and one\
-half
antifreeze that meets
“GM Specification 1825-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to
GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant c\
hange.
If you use these, you don’t need to add anything else.
