In very cold weather, 0°F (- 18 "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 110-volt AC outlet.
A I
I /! CAUTION:
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.
4. Before starting the engine, be sure to unplug and store
the cord as
it was before to keep it away from moving
engine
parts. If you don't, it could be damaged.
How long should
you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of
oil you have, and some other things. Instead of
trying to list everything here, we ask that
you contact
your
GM dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

accelerator all
the way down.
You should
use DRIVE (D) (or, as you need to, a lower
gear) when towing a trailer to minimize heat build-up
and extend the life
of your transmission.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than DRIVE
(D). You should use THIRD (3)
when carrying a heavy load or driving on steep hills.
SECOND (2): This position gives you more power
but lower fuel economy.
You can use SECOND (2) on
hills. It can help control your speed as you go down
steep mountain roads, but then you would also want
to use your brakes off and on. If you manually
select SECOND
(2), the transmission will drive in
SECOND (2). You may use this feature for reducing
torque to the rear wheels when you are trying to start
your vehicle from a stop on slippery road surfaces.
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND
(2). You can
use it on very steep hills, or in deep
snow or mud. If
the selector lever is put in FIRST( l), the transmission
won’t shift into first gear until the vehicle is going
slowly enough.
NOTICE:
If your rear wheels can’t rotate, don’t try to
drive. This might happen if you are stuck in
very deep sand or mud or are
up against a solid
object. You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transmission. Use your brakes or shift into
PARK (P) to hold your vehicle in position
on
a hill.

Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast you’re
going, how much fuel you’re using, and many other things you’ll \
need to know to drive safely and economically.

Downloaded from www.Manualslib.com manuals search engine If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier
in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn
you if there is a problem.

It is also a reminder to

Malfunction Indicator Lamp (Service
Engine Soon Light) (Gasoline Engine)
Your vehicle is equipped
with
a computer which
monitors operation of the
fuel, ignition and emission
control systems.
SERVICE
ENGINE SOON
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions
are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
(In Canada, OBD IT is replaced by
Enhanced Diagnostics.) The SERVICE
ENGINE SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often
will be indicated
by the system before any problem is apparent. This may
prevent more serious damage to
your vehicle. This
system is
also designed to assist your service technician
in correctly diagnosing any malfunction.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
1 NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead
to costly repairs that may not be
l covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light
will also come on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system
on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required. The following
may prevent more serious damage
to
your vehicle:
0 Reducing vehicle speed.
Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled
as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn
the key off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle
to your
dealer or qualified service center for service.

Downloaded from www.Manualslib.com manuals search engine If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries
out. A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently
as designed since small amounts of
air are sucked
into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure
to install the fuel cap properly. It
will take a few driving trips
to turn the light off.
Have
you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not
to run as efficiently as designed. You may
notice this
as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once
the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change
the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has
the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
