●The tilt sensor detects changes in vehicle inclination, such as when the vehicle 
is towed away. 
This system is designed to deter and pr event vehicle theft but does not guarantee 
absolute security against all intrusions.

set. ( P. 91)
■Canceling the intrusion sensor and tilt sensor

sensor cancel switch.
A message will be shown on the multi-information display in the
