42 1-1. For safe use
NX300h_U_OM78007U Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). 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 moti on of the occupants.SRS airbag system components

Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating. ●
The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the follo wing distance of the obstacle, the
buzzer sounds continuously.
• Front corner sensors: Approximately 1.0 ft. (30 cm)
• Front center sensors: Approximately 1.0 ft. (30 cm)
• Rear corner sensors: Approximately 1.0 ft. (30 cm)
• Rear center sensors: Approximately 1.2 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 long tone, followed by fast beeps.
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 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
