For safety and security
RC F_U Your vehicle is equipped with ADVA NCED 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.SRS airbag system components

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 (RC350/RC3 00): Approximately 1.0 ft. (30 cm)
• Corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Appr oximately 1.1 ft. (35 cm)●
When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If on e or both come within the above dis-
tances, the beep will repeat a lo ng tone, followed by fast beeps.
The diagram shows the detection range of th e sensors. Note that the sensors cannot
detect obstacles that are extremely close to the vehicle.
The range of the sensors may change depe nding on the shape of the object etc.Detection range of the sensors 
