The power sounder provides an
audible alarm which is distinct from
the vehicle’s horn. It has its own
power source, and can sound an alarm

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.

sun glasses. .
Make sure there are no
obstructions blocking the sensors

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
Operation08.
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

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

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
