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

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.

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.
