PASS-Key III+ uses a radio frequency transponder in
the key that matches a decoder in the vehicle.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle is equipped with the 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.
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 shuts down the vehicle’s
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. 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 message
comes on, the key may have a damaged transponder.
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 instrument panel PASS
KEY fuse. If the engine still does not start with the
other key, your vehicle needs service. If your vehicle
does start, the first key may be faulty. See your
dealer/retailer or a locksmith who can service the
PASS-Key
®III+ to have a new key made. SeeFuses
and Circuit Breakers on page 5-104.
It is possible for the PASS-Key
®III+ decoder to learn
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. This
procedure is for learning 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.
2-17

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 key:
1. Verify the new key has
1stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder 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 key to be programmed and turn it to
ON/RUN within 10 seconds of removing the
previous key.
The security message will turn off once the key has
been programmed. It may not be apparent that
the security message went on due to how quickly
the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you lose or damage a 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:The 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 the 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. SeeTowing
a Trailer on page 4-28for the trailer towing
capabilities of the vehicle and more information.
Following break-in, engine speed and load can
be gradually increased.

This light comes on briefly while starting the engine.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the light comes on and stays on, it means that oil is
not flowing through the engine properly. The vehicle
could be low on oil and it might have some other system
problem.

Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
chargers, vehicle convenience accessories, and external
electronic devices are plugged into the accessory
power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause station
frequencies to interfere with each other. For better radio
reception, most AM radio stations boost the power levels
during the day, and then reduce these levels during the
night. Static can also occur when things like storms and
power lines interfere with radio reception. When this
happens, try reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals reach
only about 10 to 40 miles (16 to 65 km). Tall buildings or
hills can interfere with FM signals, causing the sound to
fade in and out.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when making
or receiving phone calls, charging the phone’s battery, or
simply having the phone on. This interference causes an
increased level of static while listening to the radio. If
static is received while listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged as long as it is securely attached
to the base. If the mast becomes slightly bent, straighten
it out by hand. If the mast is badly bent, replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand.

The Certification/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR). To find
out the actual loads on your front and rear axles,
you need to go to a weigh station and weigh your
vehicle. Your dealer can help you with this. Be sure
to spread out your load equally on both sides of the
centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
And, if you do have a heavy load, you should
spread it out.
{CAUTION:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
•Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
•Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
•Do not leave an unsecured child restraint
in your vehicle.
•When you carry something inside the
vehicle, secure it whenever you can.
•Do not leave a seat folded down unless
you need to.
Add-On Equipment
When you carry removable items, you may need
to put a limit on how many people you carry
inside your vehicle. Be sure to weigh your vehicle
before you buy and install the new equipment.
