Driving Through Deep Standing
Water
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s
air intake and badly damage your
engine. If you can’t avoid deep puddles or
standing water, drive through them very slowly.
Engine Block Heater (Canada Only)
In very cold weather, 0 F (- 18 C) or colder, the engine
block heater can help. You’ll get easier starting and
better
fuel economy during engine warm-up.
To use the block heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.
I
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
IlO-volt outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
I
I
x; NOTICE:
k After you’ve used the block heater, be sure to
:; store the cord as it was before, to keep it away
i from moving engine parts. If you don’t, it could
:: be damaged. .’, :.,* :>”!;.:,.”~ i” < .:-;:.&,a2% && ?3$?%7 -
How long should you keep the block heater plugged in?
The answer depends
on the weather, the kind of oil you
have, and some other things. Instead
of trying to list
everything here, we ask that you contact a Buick dealer
in the area where you’ll be parking your vehicle. The
dealer can give
you the best advice for that particular
area.

HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating”
in the Index.
Low Coolant Warning Light
If this light comes on, your
system is low
on coolant
and the engine may
overheat.
See “Engine Coolant” in the Index and have your
vehicle serviced as soon
as you can.
Engine Oil Pressure Gage
OIL
I
You can read your engine
oil pressure directly from
the gage on your instrument
panel.
If the gage reads in the red band and stays there, it
means oil isn’t going through your engine properly.
You
could be low on oil, or you might have some other oil
problem. Have your vehicle serviced as soon as you can.
ProCarManuals.com

Don’t keep driving if the oil pressure is low. If &I
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon
as possible and have
your vehicle serviced.

Volts Gage
The “VOLTS” gage shows
voltage in the electrical
system. The normal range
is
11 to 15 volts. If the gage
reading stays in either red
range, have your Buick
dealer check the electrical
system.

checked by your Buick
dealer.

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
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into “P’
(Park) yet.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift to “P” (Park).
Release the regular brakes.
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
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.

If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it
cools down. The

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant leveI
isn’t at or above “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.)

liquid like alcohol, can boil before the prope
coolant mix will. Your vehicle’s coolant warn
system
is set for the proper coolant mix. Wit
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheal
warning. Your engine could catch fire and you or
others could be burned. Use a

gasolines with these blending materials, such as MTBE
and ethanol. By doing
so, you can help clean the air,
especially
in those parts of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that
you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators
if their
gasolines contain detergents and oxygenates, and
if they
have been reformulated
to reduce vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous
use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that means costly repairs that 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).
