Theft-Deterrent Systems
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.

Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder
is turned with a valid key. If a correct key is not
used or the ignition lock cylinder is tampered with,
the fuel system is disabled and the vehicle will
not start.
During normal operation, the security light will turn
off approximately ve seconds after the key is
turned to RUN.
If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light comes
on, you will be able to restart the engine if you turn
the engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®
at this time. You may also want to check the fuse.
SeeInstrument Panel Fuse Block on page 504and
Underhood Fuse Block on page 507. See your
dealer for service.
In an emergency, call the Roadside Assistance
Center. SeeRoadside Assistance Program
on page 542.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Keep your speed at 55 mph (88 km/h)
or less for the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake, or slow,
the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not 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.
Do not tow a trailer during break-in. See
Towing a Trailer on page 374for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load can
be gradually increased.

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
The Retained Accessory Power (RAP) feature will
allow certain features on your vehicle to continue to
work for up to 10 minutes after the ignition key is
turned to LOCK or until one of the doors is opened.
Starting the Engine
Place the transmission in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position – this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not 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.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. Do not
race the engine immediately after starting it.
Operate the engine and transmission gently to
allow the oil to warm up and lubricate all
moving parts.

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components. If
the ignition key is turned to the START position,
and then released when the engine begins
cranking, the engine will continue cranking for a
few seconds or until the vehicle starts. If the
engine does not start and the key is held in
START for many seconds, cranking will be
stopped after 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine is
already running. Engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts brie y but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently until the oil
warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.

{CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or
someone else could be seriously injured.
Be sure to set the parking brake before
placing the transfer case in NEUTRAL.
SeeParking Brake on page 133.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transmission. The repairs would not be
covered by your warranty. 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, seeIf Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 357.NEUTRAL (N):In this position, your engine does
not connect with the drive wheels. To restart when
you are already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than about 35 mph (55 km/h),
push your accelerator pedal about
halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
You will shift down to the next gear and have
more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 316.
DRIVE (D) can be used when towing a trailer,
carrying a heavy load, driving on steep hills or for
off-road driving. You may want to shift the
transmission to THIRD (3) or, if necessary, a lower
gear selection if the transmission shifts too often.THIRD (3):This position is used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
SECOND (2):This position reduces vehicle speed
even more than THIRD (3) without using your
brakes. You can use SECOND (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 (2), the
transmission will drive in second gear. You may
use this feature for reducing the speed of the rear
wheels when you are trying to start your vehicle
from a stop on slippery road surfaces. Once
the vehicle is moving, shift into DRIVE (D).

brake pedal.
2. Shift the transmission to NEUTRAL (N) and
turn the ignition to RUN with the engine off.
3. Press the button for the desired transfer case
shift position (Four-Wheel High,
Four-Wheel-High Lock, or
Four-Wheel-Low Lock).
4. After the transfer case has shifted out of
NEUTRAL the red light will go out.
Notice:Shifting the transmission into gear
before the indicator light stops ashing could
cause damage to the transfer case. Always
wait until the indicator light stops ashing
before putting the transmission back in gear.

Flash-to-Pass
This feature lets you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will
turn on. They will stay on as long as you hold the
lever toward you. The high-beam indicator on
the instrument panel cluster will come on. Release
the lever to return to normal operation.
Windshield Wipers
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the
band to mist. Hold it there until the wipers
start. Then let go. The wipers will stop after
one wipe. If you want more wipes, hold the
band on mist longer.
6(Delay):You can set the wiper speed for a long
or short delay between wipes. This can be very
useful in light rain or snow. Turn the band to
choose the delay time. The closer to the top of the
lever, the shorter the delay.
6(Low Speed):For steady wiping at low
speed, turn the band away from you to the
rst solid band past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band
to off.
Be sure to clear ice and snow from the wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If
your blades do become worn or damaged, get
new blades or blade inserts.
