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 dealer in the area where you’ll be parking your
vehicle. The dealer can give
you the best advice for that
particular area.
Automatic Transmission Operation
There are several different positions for your shift lever.
Your vehicle is equipped with an automatic
transmission, and it features an electronic shift position
indicator within the instrument cluster. This display
must be powered anytime the shift lever is capable of
being moved out of the
PARK (P) position. This means
that
if your key is in the OFF position, but not locked,
there will be a small current drain
on your battery which
could discharge your battery over a period
of time. If
you have a need to leave your key in the ignition in the
OFF position for an extended period for any reason, it is
recommended that
you disconnect the battery cable from
the battery
to prevent discharging your battery.
/DI 3 121 1 vehicle can’t move easily.
PARK (P): This locks your rear wheels. It’s the best
position to
use when you start your engine because your

Downloaded from www.Manualslib.com manuals search engine 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.

engine is running. Canadian
vehicles indicate pressure in kPa (kilopascals).
OIL Wh
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem causing low
oil pressure. Check your oil as soon as possible.

Don’t keep driving if the oil pressure is low. If
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and

The light will stay on until the engine starts. If the

fails to start, see “Passlock” in
the Index.
If the light comes
on continuously while driving and
stays on, there may be a problem with the Passlock
System.
Your vehicle will not be protected by Passlock,
and you should see your
GM dealer.

Downloaded from www.Manualslib.com manuals search engine If your vehicle is equipped with the AM-FM Stereo with
Cassette Tape Player and Automatic
Tone Control:
1. Turn the ignition to RUN or ACC.
2. Turn the radio off.
3. Press and hold the TAPE AUX button for five
seconds. The tape symbol
on the display will flash
for two seconds.
4. Insert the scrubbing action cleaning cassette while
the tape symbol is flashing.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature
is active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with
a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use
of a non-scrubbing action, dry-type cleaning
cassette
is not recommended. After you
clean the player, press and hold EJECT for
five seconds to reset the
CLN indicator. The radio will
display
--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before
you have your tape
player serviced.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface
of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges
or the
edge
of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk
of contaminating the lens of the CD optics with
lubricants internal
to the CD mechanism.

Downloaded from www.Manualslib.com manuals search engine 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
GM
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?

NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
lhrn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a heavy-duty turn signal flasher (included in
the optional trailering package).
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.
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 and reduce your
speed
to around 45 mph (70 kdh) to reduce the
possibility of engine and transmission overheating.
When towing at high altitude
on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than
at normal altitudes. If you turn your
engine
off immediately after towing at high altitude on
steep uphill grades, your vehicle may show signs similar
to
engine overheating. To avoid this, let the engine run while
parked (preferably
on level ground) with the automatic
transmission in PARK
(P) for a few minutes before tumine
the engine off. If you do get the overheat warning, see
“Engine Overheating”
in the Index.
