2-10 Keys, Doors and Windows
Here is how to avoid setting off the
alarm by accident:
.If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock a door with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm.
If you set off the alarm by accident,
you can turn off the alarm by
pressing UNLOCK on the RKE
transmitter. The alarm will not stop if
you try to unlock a door any
other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system by locking the doors
with the RKE transmitter.
2. Unlock the door with the manual door lock and open the door.
This should set off the alarm. 3. To turn the alarm off, press the
UNLOCK button on the RKE
transmitter or start the engine.
If the alarm does not sound when it
should but the lights flash, check to
see if the horn works. The horn fuse
may be blown. To replace the fuse,
see Fuses and Circuit Breakers on
page 10‑40.
If the alarm does not sound or the
front turn signal lamps do not flash,
see your dealer for service.

Immobilizer Operation
(PASS-Key III+
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

Keys, Doors and Windows 2-11
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 10‑40. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer 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 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 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 for service.
5. After the engine has started, turn the key to LOCK/OFF, and
remove the key. Insert the key to
be programmed and turn it to
ON/RUN within ten seconds of
removing the previous key.
The security light turns off once
the key has been programmed. 6. Repeat Steps 1 through 5 if
additional keys are to be
programmed.
If the security light comes on and
stays on while driving, the engine
will restart if you turn it off. However,
the theft-deterrent system is not
working properly and must be
serviced by your dealer. The vehicle
is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑7 orRoadside
Assistance Program (Mexico) on
page 13‑9.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.

Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

Ashtrays
The vehicle may have a removable
ashtray and cigarette lighter.
The ashtray is located in the center
console area. The ashtray can be
removed for cleaning. When the
ashtray is removed, this area can
also be used as a cupholder.
Notice:If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.Chime Level Adjustment
The radio is used to adjust the
vehicle's chime level. To change the
volume level of the chime, press
and hold pushbutton 6 with the
ignition on and the radio power off.
The volume level will change from
the normal level to loud, and LOUD
will appear on the radio display. To
change back to the default or
normal setting, press and hold
pushbutton 6 again. The volume
level will change from the loud level
to normal, and NORMAL will appear
on the radio display. Each time the
chime volume is changed, three
chimes will sound to indicate the
new volume selected. Removing the
radio and not replacing it with a
factory radio or chime module will
disable vehicle chimes.
