Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course, you'll find experienced and able service
experts in Buick dealerships all across North America.
They'll be ready and willing to help if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up
-to-date maps?

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.

5-9
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº and ªRecreational Vehicle Towingº in
the Index.
Engine Overheating
You will find a coolant temperature gage and a hot
engine warning light on your instrument panel. See
ªEngine Coolant Temperature Gageº and ªEngine
Coolant Temperature Warning Lightº in the Index.
You also have a LOW COOLANT warning light on
your instrument panel. See ªLow Coolant Warning
Lightº in the Index.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
Should an overheated engine condition exist, an
overheat protection mode which alternates firing groups
of cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The low coolant light may come on and
the temperature gage will indicate an overheat condition
exists. 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 and change the
oil. See ªEngine Oilº in the Index.

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Electric Engine Cooling Fans
B. Radiator Pressure Cap
C. Coolant Recovery Tank
CAUTION:
An electric engine cooling 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 recovery tank is boiling,
don't do anything else until it cools down.
When the engine is
cold, the coolant level
should be at or above
the COLD mark on the
coolant recovery tank.
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.

5-14 How to Add Coolant to the Coolant
Recovery Tank
If you haven't found a problem yet, but the coolant level
isn't at the COLD mark, add a 50/50 mixture of clean,
drinkable water and DEX
-COOL engine coolant at the
coolant recovery tank. See ªEngine Coolantº in the
Index for more information.
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 mixture will. Your vehicle's coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean, drinkable water
and DEX
-COOL coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

CAUTION:
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.
3. Remove the 3800 Series II V6 engine cover shield to
access the bleed valve.
A. Clean the area around the engine oil fill tube and cap
before removing. Twist the oil fill tube, with cap
attached, counterclockwise and remove it.
B. If you have the supercharged engine, remove the nut
in the center of the cover shield.
C. Lift the engine cover shield at the front, slide the
catch tab out of the engine bracket and remove the
cover shield.
D. Put the oil fill tube, with cap attached, in the
valve cover oil fill hole until you're ready to replace
the cover shield.

4. After the engine
cools, open
the coolant air
bleed valve.
There is one bleed valve. It is located on the
thermostat housing.
5. Fill the radiator
with the proper
DEX
-COOL
coolant mixture, up
to the base of the
filler neck. See
ªEngine Coolantº
in the Index for
more information
about the proper
coolant mixture.If you see a stream of coolant coming from an
air bleed valve, close the valve. Otherwise, close the
valve after the radiator is filled.
6. Rinse or wipe any spilled coolant from the engine
and the compartment.
7. Replace the 3800 Series II V6 engine cover shield.
A. Remove the oil fill tube, with cap attached, from
the valve cover.
B. Insert the catch tab on the cover shield under the
bracket on the engine.
C. Place the hole in the cover shield over the hole in
the valve cover. Install oil fill tube and cap by
twisting clockwise.
D. If you have the supercharged engine, install the
nut in the center of the cover shield.

CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
8. Install the spare tire.
Put the wheel nuts back
on with the rounded end
of the nuts toward the
wheel. Tighten each nut
by hand until the wheel
is held against the hub.
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
