Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
I These mean there is something that could damage your vehicle.
In the notice area, we tell you about something that can damage your
vehicle. Many times, this damage would
not be covered by your warranty,
and it could be costly. But the notice will
tell you what to do to help avoid
the damage.
When you read other manuals, you might
see CAUTION and NOTICE
warnings in different colors or
in different words.
You'll also see warning labels on your vehicle. They use yellow for
cautions, blue for notices and the words CAUTION or NOTICE.

Leaving Your Vehicie
If you are leaving the vehicle, take your keys, open your door and set the
locks from inside. Then get out and close the door.
Keyless Entry System
If your vehicle has this option, you can lock and unlock your doors from up
to 30 feet (9 m) away using the key chain transmitter supplied with your
vehicle.

Operation
To unlock the driver’s door, press the UNLOCK button. If you press this
button again within
five seconds, all the doors will unlock. Press the rear
door
UNLOCK button to unlock the rear door only.
Press the
LOCK button to lock all the doors.
The illuminated entry feature activates
the interior dome lamps for
40 seconds or until the ignition switch is turned on.
Matching Transmitterfs) To Your Vehicle
Each key chain transmitter is coded to prevent another transmitter from
unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring any remaining
transmitters with you when
you go to your dealer. When the dealer matches
the replacement transmitter
to your vehicle, the remaining transmitters must
also be matched. Once the new transmitter
is coded, the lost transmitter will
not unlock your vehicle.
You can match a transmitter to as many different vehicles as you own,
provided they are equipped with
exactly the same 17ZOdd system. (General
Motors offers several different models
of these systems on their vehicles.)
Each vehicle can have
only two transmitters matched to it.
See your dealer to match transmitters to another vehicle.
Battery Replacement
Under normal use, the batteries in your key chain transmitter should last
about two years.
You can tell the batteries are weak
if the transmitter won’t work at the
normal range in any location. If you have to get close to your vehicle before
the transmitter works,
it’s probably time to change the batteries.
Use two Duracell@ type
DL2016, or a similar type.

Automatic transrnissiox
Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won’t
start in any other position
- that’s a safety feature. To restart when you’re
already moving, use NEUTRAL
(N) only.
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.
Manual transmission:
The gear selector should be in Neutral (N). Hold the clutch pedal to the
floor and start the engine. Your vehicle won’t start
if the clutch pedal is not
all the way down
- that’s a safety feature.
To start your 5.7 Liter (Code K) or 7.4 Liter (Code N) V8 engine:
1. Without pushing the accelerator pedal, turn your ignition key to
START. When the engine starts, let
go of the key. The idle speed will
go down
as your engine gets warm.
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.
2. If it doesn’t start right away, hold your key in START. If it doesn’t start
in three seconds, push the accelerator pedal about one-quarter of the
way down for 12 more seconds, or
until it starts.

4. Wait 15 seconds to let the starter motor cool down. Then push your
accelerator pedal all
the way to the floor. Hold it there. Then hold the
key in START for
no more than ten seconds. This clears the extra
gasoline from the engine. If the engine still doesn’t start, wait another
15 seconds and do Step 4 again.

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.
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.
2. 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.
3. If the engine does not start after 15 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, follow the
steps
in “Running Out of Fuel” (see “Diesel Fuel Requirements and Fuel
System”
in the Index).
When your 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.

information
on what fuel to use in cold weather.
lf 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.
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.
Automatic Transmission
T
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.

Charging System Warning Light
The red Charging System Warning light should come on briefly when you
turn on the ignition, before starting the engine, as a check to show you it is
working. After the engine starts, the light should go out. If it stays on or
conles on while you are driving, you may have a problem with your
charging system.
It could indicate a problem with the alternator drive belt,
or some other charging system problem. Have
it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light on, it helps to turn off all
your accessories, such
as the radio and air conditioner.
Malfunction indicator (Service Engine Soon) Lamp
A computer monitors the operation of your fuel, ignition and emission
control systems.
This orange light should come on when the ignition is on
but the engine is
not running, as a check to show you it’s working. If it does
not come on at all, have
it fixed right away. If it stays on, or comes on while
you are driving, the computer is indicating that you have a problem. You
should take your vehicle in for service soon.

Voltmeter
When your engine is not running, but the ignition is in the RUN position,
this gage shows your battery’s state of charge
in DC volts.
When
the engine is running, the gage shows the condition of the charging
system. Readings between the low and high warning zones indicate
the
normal operating range.
Readings in the low warning zone may occur when a large number
of
electrical accessories are operating in the vehicle and the engine is left at an
idle
for an extended period. This condition is normal since the charging
system
is not able to provide full power at engine idle. As engine speeds are
increased,
this condition should correct itself as higher engine speeds allow
the charging system
to create maximum power.
You can only drive for a short time with the reading in either warning zone.
If you must drive, turn off all unnecessary accessories.
Readings in either warning zone indicate a possible problem
in the electrical
system. Have the vehicle serviced as soon as possible.
