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.
