audible alarm, which is distinct from
the vehicle’s horn. It has its own
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 a change in vehicle
orientation.
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
sunshades.
. Make sure there are no
obstructions blocking the sensors
in the front overhead console.
Inclination and Intrusion
Sensors Disable Switch
It is recommended that the intrusion
and inclination sensors be deactivated
if pets are left in the vehicle or if the
vehicle is being transported.
