Canceling and automatic re-enabling of the intrusion sensor and tilt sensor
The alarm will still be set even when the intrusion sensor and tilt sensor are can-
celed.
After the intrusion sensor and tilt sensor are canceled, pressing the power
switch or unlocking the doors using the entry function or wireless remote con-
trol will re-enable the intrusion sensor and tilt sensor.
The intrusion sensor and tilt sensor will automatically be re-enabled when the
alarm system is deactivated.
Intrusion sensor detection considerations
The sensor may trigger the alarm in the following situations:
Places with extreme vibrations or noises, or situations in which the vehicle is
subject to repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported on a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed
• When the vehicle is in an automatic or high-pressure car wash
• When in a hail or lightning storm
A window or the moon roof is open.
In this case, the sensor may detect the fol-
lowing:
• Wind or the movement of objects such
as leaves and insects inside the vehicle
• Ultrasonic waves emitted from devices
such as the intrusion sensors of other
vehicles
• The movement of people outside the
vehicle
Unstable items, such as dangling accesso-
ries or clothes hanging on the coat hooks,
are in the vehicle.
