NOTICE:
Don't try to shift to PARK (P) if your vehicle is moving. If you
do, you could damage the transmission. Shift to
PARK (P) only
when your vehicle is stopped.
2. MmLwl ~I-~~CZ.SI~~~.YS~~CZ: Move your shift lever to NEUTRAL (N) and
hold the clutch pedal
to the floor while starting the engine. Your vehicle
won't start
if the clutch pedal is not all the wlay down - that's a safety
feature.
Turn your ignition key to
RUN.
Observe the GLOW PLUGS light. (This light may not come on if the
engine is hot.)
NOTICE:
If the GLOW PLUGS light stays on, it means that your vehicle
could have one
of several problems, so you should have it
serviced right away.
3. As soon as the GLOW PLUGS light goes off. IMMEDIATELY turn the
ignition key
to START. When the engine starts. let go of the key. (The
longer you wait to start after the light goes
off, the harder it will be to
start the engine.)
NOTICE:
Holding your key in START for longer than 15 seconds at a time
will cause your battery to
be drained much sooner. And the
excessive heat can damage your starter motor.
4. If the engine does not start after IS seconds of cranking. turn the
ignition key to OFF. Wait one minute
for the starter to cool. then try the
same steps again.
If you're trying to start your engine after you've run out of fuel. follocv the
steps
in "Running Out of Fuel" (see "Diesel Fuel Requirements and Fuel
System"
in the Index).
When
YOLI~ engine is cold. let it run for a few minutes before you move your
vehicle. This lets oil pressure build
up. Your engine will sound louder when
it's cold.

NOTICE:
If you’re not in an idling vehicle and the engine overheats, you
wouldn’t be there to see the coolant temperature gage. This
could damage your vehicle. Don’t let your engine run when
you’re not in your vehicle.
Cold Weather Starting (Diesel Engine)
The following tips will help you get good starting in cold weather.
Use
SAE IOW-30 oil when the outside temperature drops below freezing.
When the outside temperature drops below
0°F (-1 floc), use your engine
coolant heater.
If you park your vehicle in a garage, you shouldn’t need to use the coolant
heater until the garage temperature goes below
0°F (-I SOC), no matter how
cold
it is outside.
To use the engine coolant heater, first turn off the engine. Then open the
hood, unwrap the electrical cord and plug it in. It uses normal house voltage
(I 10 volts), but:
A 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 outlet.
If the cord won’t reach, use a heavy-duty three-prong extension
cord rated for
at least 15 amps.
NOTICE:
After you’ve used the coolant heater, be sure to store the cord in
the manner it was, to help keep it away from moving engine
parts.
If you don’t, it could be torn and damaged.

How long should you keep the coolant heater plugged in? The answer
depends on the weather,
the kind of oil you have, and some other things.

See “Diesel Fuel Requirements and Fuel System’’
in the Index for
information
on what fuel to use in cold weather.
If Your Diesel Engine Won’t Start
If you‘ve run out of fuel, look at “Running Out of Fuel” (see “Diesel Fuel
Requirements and Fuel System”
in the Index).
If you‘re not out of fuel, and your engine won’t start, do this:
Turn your ignition key to RUN. Make sure that the GLOW PLUGS light is
out. Then IMMEDIATELY turn the ignition key to START.
If the light doesn’t go off, wait a few seconds, then try starting your engine
again. And, see your dealer as soon as
you can for a starting system check.
If the light comes on and then goes off and you know your batteries are
charged, but your engine still won’t start, your vehicle needs service.
If the light does not come on when the engine is cold, your vehicle needs
service.
If your batteries don‘t have enough charge to start your engine, see
“Battery”
in the Index.
Be sure you have the right oil for your engine, and that you’ve changed the
oil at the proper times. If you use the wrong
oil, your engine may be harder
to start.
If the engine starts, runs a short time, then stops, your vehicle needs service.

NOTICE:
After you’ve used the coolant heater, be sure to 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 weather, the kind of oil you have. and some other things.
Inste.ad 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.
Automatic Transmission
There are several different positions for your shift lever.
If your vehicle is equipped with an automatic transmission, it now 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.
PARK (P) -This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

NOTICE:
If you keep driving your vehicle with this light on, after a while
the emission controls
won’t work as well, your fuel economy
won’t
be as good, and your engine may not run as smoothly.
This could lead
to costly repairs not covered by your warranty.
Check Gages Light
This orange light will come on briefly when you are starting the engine. If
the light comes on and stays on while you are driving, it could indicate a
problem with your vehicle.
It could be a problem with your oil pressure.
coolant temperature, or some other problem. Check your various gages
to
see if they are in the warning zones. If they are, have your vehicle serviced
right away.

Oil Pressure Gage
The oil pressure gage shows the engine oil pressure in psi (pounds per
square inch) when the engine is running. Canadian vehicles indicate
pressure
in kPa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and oil viscosity, but readings above the
low pressure
zone indicate the norn~al opcrating ranse.
A reading in the low pressure zone may bc caused by a dangemusly low oil
level or other problem causing low oil pressure. Check your oil as soon as
possible.
A CAUTION:
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.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and is not covered by your warranty.

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 GM dealers 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?
FueZ, 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?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or
whatever.
There
is something about an easy stretch of road with the same scenery,
along with the
hum of the tires on the road, the drone of the engine, and the
rush
of the wind against the vehicle that can make you sleepy. Don’t let it
happen
to you! If it does, your vehicle can leave the road in less than a
second, and you could crash and be injured.

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 (Pj (or the manual transmission
out
of gear and the parking brake applied) for a few minutes before turning
the engine off.
If you do get the overheat warning, see “Engine
Overheating”
in the Index.
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.
6.
Apply your regular brakes, but don’t shift into PARK (P) yet, or in gear
for a manual transmission.
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.
Re-apply the regular brakes. Then apply your parking brake, and then
shift
to PARK (P), or REVERSE (Rj for a manual transmission.
If you have
a four-wheel-drive vehicle, be sure the transfer case is in a
drive gear-not in NEUTRAL
(N).
Release the regular brakes.
A CAUTION:
It can be dangerous to get out of your vehicle if the shift lever is
not fully in
PARK (P) with the parking brake firmly set. Your
vehicle can rofl.
If you have Ieft the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle
won’t move, even when you’re on fairly level ground, use the
steps that follow.
If you have four-wheel drive and your transfer case is in
NEUTRAL (N), your vehicle will be free to roll, even if your
shift lever is in
PARK (P). So, be sure the transfer case is in a
drive gear
- not in NEUTRAL (N).

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 transmission fluid (don’t
overfill), engine oil, axle lubricant, 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.
