Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the RKE transmitter and close the door. Wait
approximately 30 seconds until the security
light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will ash.
You can turn off the alarm by unlocking the driver’s
door with your key, using the unlock button on the RKE
transmitter or by starting the car with a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, seeFuses and Circuit Breakers
on page 5-99. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is 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, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.If the engine does not start and the security light on
the instrument panel cluster comes on when trying to
start the vehicle, there may be a problem with your
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. At this time,
you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-99. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may
be faulty. See your dealer/retailer who can service
the PASS-Key
®III+ to have a new key made.
In an emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to learn
the transponder value of a new or replacement key. Up to
eight additional keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are lost
or do not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key
®III+ to have keys
made and programmed to the system.
2-21

See your dealer/retailer or a locksmith who can service
PASS-Key®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
To program the new additional key:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, already programmed, key in the
ignition and start the engine. If the engine will 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 new key to be programmed and turn it to
ON/RUN within ve seconds of the original key
being turned to LOCK/OFF.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you lose or damage your PASS-Key
®III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
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 for the rst
500 miles (805 km):
Do not drive at any one constant speed,
fast or slow.
Do not exceed 70 mph (113 km/h).
Do not make full-throttle starts; also refrain
from using the full throttle while driving.
Avoid downshifting to brake or slow the vehicle.
If these procedures are not followed, the engine,
axle, or other parts could be damaged.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake linings
are not yet broken in. Hard stops with new linings
can mean premature wear and earlier replacement.
Follow this break-in guideline every time you get
new linings.
2-22

Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-39for the trailer towing capabilities
of your vehicle and more information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions.
To shift out of P (Park), ignition must be in the
ON/RUN or ACC/ACCESSORY and the brake
pedal must be applied.Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.
A (LOCK/OFF):This is the only position in which you
can insert or remove the key. This position locks
the ignition, and transmission.
B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers when
the engine is off. This position will allow you to turn off
the engine.
C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running.
If you leave the key in the ACC/ACCESSORY or ON/
RUN position with the engine off, the battery could be
drained. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.

Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come on.
If it does not, you need to have the vehicle serviced.
SeeBrake System Warning Light on page 3-36for
more information.To release the parking brake, pull the release lever
located to the left of the steering wheel on the instrument
panel.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle begins to move.
To stop the chime, fully release the parking brake.

may be a strong magnetic eld interfering with the
compass. Interference can be caused by a magnetic
antenna mount, note pad holder, or similar object. If the
letter C appears in the compass window, the compass
may need to be reset or calibrated.
Calibrate the compass by driving the vehicle in circles at
5 mph (8 km/h) or less until the display reads a direction.
Compass Variance
The mirror is set to zone eight. If you do not live in zone
eight or drive out of the area, the compass variance
needs to be changed to the appropriate zone.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the URPA system, it operates at
speeds less than 3 mph (5 km/h), and assists the driver
with parking and avoiding objects while in R (Reverse).
The sensors on the rear bumper are used to detect the
distance to an object up to 5 feet (1.5 m) behind the
vehicle, and at least 10 inches (25.4 cm) off the ground.
{CAUTION:
The Ultrasonic Rear Parking Assist (URPA) system
does not replace driver vision. It cannot detect:
objects that are below the bumper, underneath
the vehicle, or if they are too close or far from
the vehicle
children, pedestrians, bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle’s mirrors.
The display is located
above the liftgate glass
and can be seen by
looking over your right
shoulder.
URPA uses three color-coded lights to provide distance
and system information.
