Theft
Vehicle theft is big business, especially in some cities. Although your
vehicle
has a number of theft-deterrent features, we know that nothing we
put on
it can make it impossible to steal. However, there are ways you can
help.
Key in the Ignition
If you walk away from your vehicle with the keys inside, it’s an easy target
for joy riders or professional thieves
- so don’t do it.
When you park your vehicle and open the driver’s door, you’ll hear a tone
reminding you to remove your key from the ignition and take it with you.
Always do this. Your steering wheel will be locked, and so will your
ignition. If
you have an automatic transmission, taking your key out also
locks your transmission. And remember
to lock the doors.

Ignition Switch
Use your key to start your vehicle. The key lets you turn the ignition switch
to
five different positions:
2
3
1. OFF
2. RUN
3. START
4. ACC
5. LOCK
ACC (Accessory): ACC lets you use things like the radio and the
windshield wipers when the engine is off. To get into ACC, push in the key
and turn it toward you. Your steering wheel will remain locked, just
as it
was before
you inserted the key.
LOCK: This position locks your ignition, steering wheel and transmission.
It’s a theft deterrent feature. You will only be able to remove your key when
the ignition is turned to LOCK.
OFF: This position lets you turn off the engine but still turn the steering
wheel.
It doesn’t lock the steering wheel like LOCK. Use OFF if you must
have your vehicle
in motion while the engine is off’ (for example, if your
vehicle is being pushed).
RUN: This is the position for driving.
START: This starts your engine.
I I
A CAUTION:
On manual transmission vehicles, turning the key to LOCK will
lock the steering column and result in
a loss of ability to steer the
vehicle. This could cause
a collision. If you need to turn the
engine
off while the vehicle is moving, turn the key only to OFF.
Don’t press the key release button while the vehicle is moving.

NOTICE:
If your key seems stuck in LOCK and you can’t turn it, be sure
it is all the
way in. If it is, then turn the steering wheel left and
right while you turn the key hard. But turn the key only with
your hand. Using
a tool to force it could break the key or the
ignition switch.
If none of this works, then your vehicle needs
service.
Key Release Button
The ignition key
cannot be removed
from the ignition of
manual transmission
vehicles unless the
key release button is
used.
To Remove the Key
On manual transmission vehicles, turn the key to the
LOCK position while
pressing the key release button
in (see the caution earlier in this section
about the key release lever). Keeping your finger
on the button, pull the key
straight
out.
On automatic transmission vehicles, turn the key to LOCK and pull it
straight out.
Starting Your Gasoline Engine
If you have a diesel engine, see “Starting Your Diesel Engine” in the Index.
Engines start differently. The 8th digit of your Vehicle Identification
Number
(VIN) shows the code letter or number for your engine. You will
find the
VIN at the top left of your instrument panel. (See “Vehicle
Identification Number”
in the Index.) Follow the proper steps to start the
engine.

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

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.

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.

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.
2-20
ProCarManuals.com

Your vehicle has a brake-transmission shift interlock. With the ignition in
the RUN position, you must fully apply your regular brakes before you can
shift from PARK (P).
If you cannot shift out
of PARK (P), ease pressure on the shift lever and
push the shift lever
all the way into PARK (P) as you continue pressing the
brake pedal. Then move the shift lever
into the gear you want. If you still
cannot shift the shift lever out of PARK (P), see “Shifting Out of PARK (P)”
later in this section.
REVERSE (R) - Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle is moving forward \
could damage your transmission. Shift to REVERSE (R) only
after your vehicle
is stopped.
To rock your vehicle back and forth to get out’of snow, ice or sand
without damaging your transmission, see “If You’re Stuck: In Sand,
Mud, Ice or Snow” in the Index.
0 NEUTRAL (N) - In this position, your engine doesn’t connect with
the wheels. To restart when you’re already moving, use NEUTRAL
(N)
only. Also, use NEUTRAL (N) when your vehicle is being towed.

NOTICE:
Damage to your transmission caused by shifting out of PARK
(P) or NEUTRAL (N) with the engine racing isn’t covered by
your warranty.
0 AUTOMATIC OVERDRIVE (@) - This position is for normal
driving. If you need more power for passing, and you’re:
- Going less than about 35 mph (56 km/h), push your accelerator
pedal about halfway down.
- Going about 35 mph (56 km/h) or more, push the accelerator all
the way down.
You’ll shift down
to the next gear and have more power.
@ should not be used when towing a trailer, carrying a heavy load,
driving on steep hills, or for off-road driving. Select THIRD
GEAR
(3) when operating the vehicle under any of these
conditions.
0 THIRD GEAR (3) - This is like @, but you never go into Overdrive.
You should use THIRD GEAR (3) when towing a trailer, carrying a
heavy load, driving on steep hills, or for off-road driving.
0 SECOND GEAR (2) - This position gives you more power but lower
fuel economy. You can use SECOND GEAR (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 GEAR (2), the transmission will drive
in second gear. 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.
2-22
ProCarManuals.com

0 FIRST GEAR (1) - This position gives you even more power (but
lower fuel economy) than SECOND GEAR (2).
You can use it on very
steep hills, or
in deep snow or mud. If the selector lever is put in FIRST
GEAR
(1 j while the vehicle is moving forward, the transmission won’t
shift
into FIRST GEAR (1) 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 were stuck in very deep sand or mud
or were 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.
Five Speed Manual Transmission
If you have a five
speed manual
transmission, this is
your shift pattern.
Here’s how to operate
your transmission:
FIRST GEAR (1) - Press the clutch pedal and shift into FIRST
GEAR (1). Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
You can shift into FIRST GEAR (1) when you’re going less than 20
mph (32 km/h). If you’ve come to a complete stop and it’% hard to shift
into FIRST GEAR (I), put the shift lever in NEUTRAL (Nj and let up
on the clutch. Press the clutch pedal back down. Then shift into FIRST
GEAR
(1).
SECOND GEAR (2) - Press the clutch pedal as you let up on the
accelerator pedal and shift into SECOND GEAR (2). Then, slowly let
up on the clutch pedal as you press the accelerator pedal.

Just before the vehicle stops, press the clutch pedal and the brake pedal,
and shift to NEUTRAL
(N).
NEUTRAL (N) - Use this position when you start or idle your
engine.
REVERSE (R) - To back up, first press down the clutch pedal. Wait
about
5 seconds for the internal parts to stop spinning and then, shift
into REVERSE (R). Let up on the clutch pedal slowly while pressing
the accelerator pedal.
NOTICE:
Shift to REVERSE (R) only after your vehicle is stopped.
Shifting to REVERSE
(R) while your vehicle is moving could
damage your transmission.
Also, use REVERSE (R), along with the parking brake, when turning
off your engine and parking your vehicle.
SHIFT Light
If you have a manual
transmission, you will
have a
SHIFT light.
This light will show
you when to shift to
the
next higher gear
for best fuel economy.
When
this light comes on, you can shift to the next higher gear if weather,
road and traffic conditions let you.
For the best fuel economy, accelerate
slowly and shift when the light comes on.
