■ Intrusion sensor detection considerations
The sensor may trigger the alar m 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 by 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 is open.
In this case, the sensor may detect the
following:
• 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 acces-
sories or clothes hanging on the coat
hooks, are in the vehicle.
