Lock the vehicle with the manual
door lock lever, the power door
lock switch, or the key, after
the doors are closed.
Unlock the doors by pressing the
unlock button on the RKE
transmitter or by contacting

a door is unlocked any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lock the
doors with the RKE transmitter.
2. Unlock the door with the manual
door lock and open the door.
The pre-alarm should sound
followed by the full alarm about
10 seconds later.
3. Press the unlock button on the
RKE transmitter or start the
engine to turn the alarm off.
If the alarm does not sound but the
lights ash, check to see if the
horn works. The horn fuse could be
blown. To replace the fuse, see
Fuses and Circuit Breakers
on page 5-91.
If the alarm does not sound or
the front turn signal lamps do not
ash, see your dealer/retailer
for service.
Passlock®(U.S. Only)
Passlock®is a passive
theft-deterrent system that enables
fuel if the vehicle is started with
a valid key. If an incorrect key
is used or the ignition lock cylinder
is tampered with, the fuel system
is disabled and the vehicle does
not start.
The security light turns off
approximately ve seconds after
the engine is started. SeeSecurity
Light on page 3-33.
If the engine stalls and the security
light ashes, wait about 10 minutes
until the light stops ashing
before trying to restart the engine.
Release the key from START
as soon as the engine starts.
If the engine does not start after
three tries, the vehicle needs
service.
2-12 Features and Controls

PASS-Key®III+ Electronic
Immobilizer Operation
(Canada Only)
This vehicle has a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from
the ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN.
You do not have to manually arm or
disarm the system.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent system.
The key uses a transponder that
matches an immobilizer control unit
in the vehicle. Only the correct
key starts the vehicle. If the key is
ever damaged, the vehicle may
not start.When trying to start the vehicle,
if the engine does not start and
the security light comes on,
there may be a problem with the
theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. Check
the fuse. SeeFuses and Circuit
Breakers on page 5-91. If the engine
still does not start with the other
key, the vehicle needs service.
If the vehicle does start, the rst
key may be faulty. See your
dealer/retailer who can service the
theft-deterrent system and have
a new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys can
be programmed for the vehicle.
The following procedure is for
programming additional keys only.Canadian Owners:If the keys
are lost or damaged, only a
dealer/retailer can service the
theft-deterrent system to have new
ones made. Two current driver’s
keys are required to program
additional keys.
To program a new key:
1. Verify that the new key has
PK3+ stamped on it.
2. Insert the current driver’s key in
the ignition and start the engine.
If the engine does not start see
your dealer/retailer for service.
3. After the engine has started,
turn the key to LOCK/OFF,
and remove the key.
4. Insert the second current driver’s
key in the ignition and start the
engine within ten seconds of
removing the previous key. If the
engine does not start see your
dealer/retailer for service.
2-14 Features and Controls

Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. An internal
thermostat in the plug-end of the
cord may exist which will prevent
engine coolant heater operation
at temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located in the engine
compartment behind the
underhood fuse block on the
driver side of the vehicle.
3. Plug it into a normal, grounded
110-volt AC outlet.
{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 re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug and store the
cord to prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Automatic Transmission
Operation
The automatic transmission has a
shift lever on the console.

Accessory Power
Outlet(s)
The accessory power outlets can be
used to connect auxiliary electrical
equipment, such as a cellular phone.

result in blown vehicle or adapter
fuses. If you experience a problem,see your dealer/retailer for additional
information on accessory power
outlets.
Notice:Adding any electrical
equipment to the vehicle can
damage it or keep other
components from working as
they should. The repairs would
not be covered by the vehicle

exceeding maximum amperage
rating of 20 amperes. Check with
your dealer/retailer before
adding electrical equipment.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment.
Notice:Improper use of the
power outlet can cause damage
not covered by the warranty.
Do not hang any type of
accessory or accessory bracket
from the plug because the
power outlets are designed for
accessory power plugs only.

Lighter
For vehicles with a removable
ashtray, it can be placed into the
cupholder and be removed for
cleaning.
Notice:If papers, pins, or other
ammable items are put in

ignite them and possibly damage
the vehicle. Never put ammable
items in the ashtray.
For vehicles with a lighter, push the
lighter down and it will pop up
when it is ready to be used.
Notice:Holding a cigarette
lighter in while it is heating does
not let the lighter back away from
the heating element when it is hot.

Environmental Concerns
Off-road driving can provide
wholesome and satisfying
recreation. However, it also raises
environmental concerns. We
recognize these concerns and urge
every off-roader to follow these
basic rules for protecting the
environment:
Always use established trails,
roads, and areas that have
been specially set aside for public
off-road recreational driving
and obey all posted regulations.
Avoid any driving practice that
could damage shrubs, owers,
trees, or grasses or disturb
wildlife. This includes
wheel-spinning, breaking down
trees, or unnecessary driving
through streams or over
soft ground.
Always carry a litter bag and
make sure all refuse is removed
from any campsite before
leaving.
Take extreme care with open
res (where permitted), camp
stoves, and lanterns.
Never park your vehicle over dry
grass or other combustible
materials that could catch re
from the heat of the vehicle’s
exhaust system.
Traveling to Remote Areas
It makes sense to plan your
trip, especially when going to a
remote area. Know the terrain and
plan your route. Get accurate
maps of trails and terrain. Check to
see if there are any blocked or
closed roads.
It is also a good idea to travel
with at least one other vehicle in
case something happens to one
of them.
For vehicles with a winch, be sure
to read the winch instructions.
In a remote area, a winch can be
handy if you get stuck but you
will want to know how to use
it properly.
