3. If your engine still won’t start (or starts but then stops),
it could be flooded with too much gasoline.
Try
pushing your accelerator pedal all the way to the floor
and holding it there as you hold the key in
START for
about three seconds.
If the vehicle starts briefly but
then stops again, do the same thing, but
this time keep
the pedal
down for five or six seconds. This clears the
extra gasoline
fi-om the engine. After waiting about
15 seconds, repeat the normal starting procedure.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you
add electrical
parts or accessories, you could change the way
the engine operates. Before qdding electrical
equipment, check with your dealer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part
of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Engine Coolant Heater (Option)
In very cold weather, .Oo F (- 18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum
of
four hours prior to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
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
110-volt AC outlet. If the cord won’t reach, use
a
heavy-duty three-prong extension cord rated for
at least 15 amps.

Move the lever up as far as it will go.
3. Move the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the Engine
Running
I
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not
fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
If
you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you’ve moved the shift lever into the PARK
(P)
position, hold the regular brake pedal down. Then, see
if you can move the shift lever away from PARK
(P)
without first pulling it toward you. If you can, it means
that the shift lever wasn’t fully locked into PARK (P).

Traction Control System Warning Light
(Option)
TRACTION
OFF
This warning light should
come on briefly as you start
the engine. If the warning
light doesn’t come on then,
have
it fixed so it will be
ready to warn you if there’s
a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel
spin. Adjust your
driving accordingly. The
traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the button
located on the instrument panel, left of the steering
column, the warning light will come on and stay on.
To turn the system back on, press the button again.
The warning light should go off. (See “Traction
Control System” in the Index for more information.)
0 If there’s a brake system problem that is specifically
related to traction control, the traction control system will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn
off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Engine Coolant Temperature
Warning Light
h -
TEMP
One of these lights will come on to tell you that your
engine coolant has overheated or your radiator cooling
fans are not working.
If you have been operating your
,vehicle under normal driving conditions, you should
pull
off the road, stop your vehicle and turn the engine
off as soon as possible. I
The section “Problems on the Road,” in this
manual explains what to
do. See “Engine Overheating”
in the Index.
Engine Coolant Temperature Gage (Option)
If’ you have the gage cluster,
you have a gage that shows
the engine coolant
temperature
in degrees
Fahrenheit. Canadian
instrument panels measure
the coolant temperature in
degrees Celsius.
-If the gage
pointer moves into the red
area, your engine is too hot!
That reading means ,the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating.your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
The section “Problems’ on the Road,” in
this
manual explains what to do. See “Engine Overheating”
in the Index.

Tbrn Signals When Towing a Trailer
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about
to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are still
working.
Your vehicle
has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out.
So, when you have a trailer
lighting system plugged in, be sure
to check your
vehicle and trailer lamps from time to time to be sure
they’re all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps
is out.
Driving On Grades
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 to THIRD (3) and
reduce your speed to around
45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
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. Apply your regular brakes, but don’t shift into
PARK (P) 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 apply your parking
5. Release the regular brakes.
brake, and the shift
to PARK
(P).

Engine Overheating
You will find a warning light about a hot engine on your
Buick instrument panel and
if you have the optional
gage cluster, a coolant temperature gage. You
will also
find a LOW COOLANT warning light.
If Steam Is Coming From Your Engine
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.
,
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered
by your warranty.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little
too hot when you:
0 Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
@ Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open
the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (a)
or THIRD (3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then, if you still have the
warning,
turn off the engine and get evejyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

The coolant level should be at or above the FULL
COLD mark. If it isn't, you may have a leak in the
radiator hoses, heater hoses, radiator, water
purnp or
somewhere elsC
in the-cooling system..
I A CAUTION:
I
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.
I NOTICE:
Engine damage from running your engine
without coolant isn't covered
by your warranty.
If there seems to be no leak, with the engine on, 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
Recovery Tank
If you haven’t found a problem yet, but the coolant
level isn’t at or above the FULL COLD
mark, add a
50/50 mixture of clean water (preferably distilled) and
DEX-COOL
TM (orange-colored, silicate-free) antifreeze
at the coolant recovery tank.
(See “Engine Coolant” in
the Index for more information.)
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 TM antifreeze.
I 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 mix.
