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).

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.

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.

it was before to keep
it away from moving engine parts. If you

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.

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.

display an error and eject the cartridge. This is normal and is the result of an
added feature
in the tape player that detects broken tapes. If an e.rror occurs,
you
will need to insert the cleaning cassette at least 3 times to thoroughly
clean the tape player.
You may prefer to use
a non-scrubbing action, wet-type cleaner. This type
of cleaner uses
a fabric belt to clean the tape head. This type of cleaner
cassette will
not cause an error, but it may not clean the tape player as
thoroughly as the scrubbing type cleaner.
A scrubbing action cleaner cassette is available through your retailer (SPO
# 12344600).
Cassettes are subject to wear and the sound quality may degrade over time.
Always verify that the cassette tape is
in good condition and the tape player
is clean before obtaining service on your tape player.
NOTICE:
Cassette tape adapter kits for portable CD players will not work
in your cassette player. These adapters
will cause the radio to
display an error and the adapter cassette
will be ejected.
Care of 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.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes without be.ing
damaged.
If the mast should ever become slightly bent, you can straighten it
out by hand. If the mast is badly bent, as it might be by vandals, you should
rep1 ace it.
Check every once
in a while to be sure the mast is still tightened to the
fender.
