A CAUTION:
Leaving young children in a vehicle with the ignition key is
dangerous
for many reasons. A child or others could be badly
injured
or even killed.
They could operate power windows or other controls or even
make the vehicle move. Don’t leave the keys in a vehicle w\
ith
young children.

Your vehicle has one
double-sided key for
the ignition and all
door locks.
If you ever lose your keys, your dealer will be able to assist you with
obtaining new ones.
NOTICE:
Your vehicle has a number of new features that can help prevent
theft. But you can have a lot
of trouble getting into your vehicle
if you ever lock your key inside. You may even have to damage
your vehicle to get in.
So be sure you have an extra key.

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.

To replace the batteries:
1. Insert a dime in the side seam of the transmitter housing, near the key
ring hole.

printed side down.
4. Align the housing and snap the halves together.
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.

Parking at Night
Park in a lighted spot, close all windows and lock your vehicle. Remember
to keep your valuables out
of sight. Put them in a storage area, or take them
with
you.
Parking Lots
If you park in a lot where someone will be watching your vehicle, it’s best
to lock it up and take your keys. But what if you have to leave your ignition
key? What if you have
to leave something valuable in your vehicle‘?
0 Put your valuables in a storage area, like your glove box.
Lock all the doors except the driver’s.
New Vehicle “Break-ln”
NOTICE:
Your modern vehicle doesn’t need an elaborate “break-in.” But
it will perform better in the long run if you follow these
guidelines:
0 Keep your speed at 55 mph (88 km/h) or less for the first 500
miles (SO4 km).
Don’t drive at any one speed - fast or slow - for the first
500 miles (804 km). Don’t make full-throttle starts.
Avoid making hard stops for the first 200 miles (322 km) or
so. During this time your new brake linings aren’t yet broken
in. Hard stops with new linings can mean premature wear and
earlier replacement. Follow this “breaking-in” guideline
every time you get new brake linings.
Don’t tow a trailer during “break-in.” See “Towing a Trailer”
in the Index for more information.

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.

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.
Hot Engine Restart (Vehicles With 5.7L LO5 Engine and Over 8500 lbs.
GVWR):
If your engine is already hot and then stalls, turn your ignition key to OFF.
Then turn your key to RUN and wait 20 seconds before you restart your
engine. When the engine starts, let
go of the key and the accelerator pedal.

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.

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.
