3. After 30 seconds the alarm system willarm. Pressing
Qon the RKE transmitter
a second time will bypass the 30-second
delay and immediately arm the alarm
system.
The vehicle alarm system will not arm if the
doors are locked with the key.
If the driver door is opened without first

When the alarm is activated, the turn
signals flash and the horn sounds for about
30 seconds. The alarm system will then
re-arm to monitor for the next unauthorized
event.
Disarming the Alarm System
To disarm the alarm system or turn off the
alarm if it has been activated:
.PressKon the RKE transmitter.
.Unlock the vehicle using the Keyless
Access system.
.Start the vehicle.
To avoid setting off the alarm by accident:
.Lock the vehicle after all occupants have
left the vehicle and all doors are closed.
.Always unlock a door with the RKE
transmitter or use the Keyless Access
system.
Unlocking the driver door with the key will
not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
IfKis pressed and the horn chirps and the
lights flash three times, the alarm was
activated while the alarm system was
armed.
If the alarm system has been activated, a
message will appear on the Driver
Information Center (DIC).
Immobilizer
See Radio Frequency Statement 0357.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system. The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the Remote Keyless Entry (RKE)
transmitter leaves the vehicle.
The immobilization system is disarmed
when the ignition is turned on or in ACC/
ACCESSORY and a valid RKE transmitter is in
the vehicle.
The security light, in the instrument cluster,
comes on if there is a problem with arming
or disarming the theft-deterrent system.
The system has one or more RKE
transmitters matched to an immobilizer
control unit in the vehicle. Only a correctly
matched RKE transmitter will start the
vehicle. If the transmitter is ever damaged,
you may not be able to start the vehicle.
When trying to start the vehicle, the
security light may come on briefly when the
ignition is turned on.

Keys, Doors, and Windows 25
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the ignition will not change from off to
on or ACC/ACCESSORY, and the RKE
transmitter appears to be undamaged, try
another transmitter. Or, you may try placing
the transmitter in the cupholder in the
center console. SeeRemote Keyless Entry
(RKE) System Operation 07.
If the vehicle will not start with the other
transmitter, or with the transmitter in the
cupholder, the vehicle needs service. If the
vehicle does start, the first transmitter may
be faulty. See your dealer who can service
the theft-deterrent system and have a new
RKE transmitter programmed to the vehicle.
It is possible for the immobilizer system to
learn new or replacement RKE transmitters.
Up to eight transmitters can be
programmed to the vehicle. To program
additional transmitters, see “Programming
Transmitters to the Vehicle” underRemote
Keyless Entry (RKE) System Operation 07.
Do not leave the transmitter 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

before changing lanes.
The passenger side mirror is convex shaped.
A convex mirror's surface is curved so more

Windows{
Warning
Never leave a child, a helpless adult, or a
pet alone in a vehicle, especially with the
windows closed in warm or hot weather.
They can be overcome by the extreme
heat and suffer permanent injuries or
even death from heat stroke.
The vehicle aerodynamics are designed to
improve fuel economy performance. This
may result in a pulsing sound when one
window is down and the other three are up.
To reduce the sound, open another window
or the sunroof, if equipped.
Power Windows
{Warning
Leaving children in a vehicle with a
Remote Keyless Entry (RKE) transmitter is
dangerous and children or others could
be seriously injured or killed. They could
operate the power windows or other
controls or make the vehicle move. The
windows will function with the RKE
transmitter in the vehicle, and children or
others could be caught in the path of a
closing window. Do not leave children in
a vehicle with an RKE transmitter.
The power windows work when the ignition
is on, in ACC/ACCESSORY, or when Retained
Accessory Power (RAP) is active. See
Retained Accessory Power (RAP) 0205.
Using the window switch, press to open or
pull to close the window.
The windows may be temporarily disabled if
they are used repeatedly within a
short time.
