The power sounder provides an
audible alarm which is distinct from

power source, and can sound an alarm
if the vehicle’s battery is
compromised. The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as when a tire is
removed. Make sure the vehicle's
alarm is not armed prior to any
jacking.
The intrusion sensor monitors the
vehicle interior, and can activate the
alarm if it senses 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 sun
glasses.
.Make sure there are no obstructions
blocking the sensors in the front
overhead console.

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 turned
on or to ACC/ACCESSORY and a valid
remote key 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 remote
keys matched to an immobilizer
control unit in the vehicle. Only a
correctly matched remote key will
start the vehicle. If the remote key 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.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 remote key appears to be
undamaged, try another remote key.
Or, you may try placing the remote
key in the backup location. See
Remote Keyless Entry (RKE) System
Operation
07.
If the ignition modes will not change
with the other remote key or in the
backup location, the vehicle needs
service. If the ignition does change
modes, the first remote key may be
faulty. See your dealer.
It is possible for the immobilizer
system to learn new or replacement
remote keys. Up to eight remote keys
can be programmed for the vehicle. To
program additional remote keys, see
“Programming Remote Keys to the
Vehicle ”under Remote Keyless Entry
(RKE) System Operation 07.
Do not leave the remote 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.
