the DIC.
Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have an inclination
sensor, an intrusion sensor, and power
sounder.
The power sounder provides an
audible alarm that is different from
the vehicle’s horn. It has its own
power source, and can sound an alarm
when the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation.
The intrusion sensor monitors the
vehicle interior, and can set off the
alarm if it senses an unauthorized
entry into the vehicle’s interior. Do
not allow passengers or pets to remain
in the vehicle when the intrusion
sensor is activated. Before arming the theft-deterrent
system and activating the intrusion
sensor:
.
Make sure all doors and windows
are completely closed.
. Secure any loose items such as a
sunshades.
. Make sure there are no
obstructions blocking the sensors
in the front overhead console.

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 transmitter pocket
located in the center console. See
Remote Keyless Entry (RKE) System
Operation08.
If the ignition mode will not change
with the other transmitter or in the
transmitter pocket, 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 08.
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.
