Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (F MVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.

■Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●The buzzer beeps faster as the vehicl e approaches an obstacle. When the
vehicle comes within the following di stance of the obstacle, the buzzer
sounds continuously:
• Front center sensors: Ap proximately 1.0 ft. (30 cm)
• Corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)
●When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If one or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 1.6 ft. (50 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows th e detection range
of the sensors. Note that the sensors
cannot detect obstacles that are
extremely close to the vehicle.
The range of the sensors may change
depending on the shape of the object
etc.
