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.
