{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.

KEYS, DOORS, AND WINDOWS 51
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 DIC.
Immobilizer
See Radio Frequency Statement 0350.
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 vehicle is
turned off.
The immobilization system is
disarmed when the ignition is on or in
ACC/ACCESSORY and a valid
transmitter is present 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 your
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
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 vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the front cupholder
located in the center console.

52 KEYS, DOORS, AND WINDOWS
If the ignition mode will not change
with the other transmitter or in the
front cupholder, your vehicle needs
service. If the ignition does change
modes, 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 for
the vehicle. To program additional
transmitters, see“Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 029.
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.

desired direction.
