*1: Parking brake engaged warning buzzer:
A buzzer will sound if the vehicle is driven at a speed of approximately 3
mph (5 km/h) or more.
*2: Open door warning buzzer:

not fully closed (with the vehicle having reached a speed of 3 mph [5 km/h]).
*3: Driver’s and front passenger’s seat belt buzzer:
The driver’s and front passenger’s seat belt buzzer sounds to alert the
driver and front passenger that
his or her seat belt is not fastened. The
buzzer sounds intermittently for 10 seconds after the vehicle reaches a
speed of 12 mph (20 km/h). Then, if the seat belt is still unfastened, the
buzzer will sound in a different tone for 20 more seconds.

sensors, side impact sensors (front door), side impact sensors (rear), safing
sensor (rear), driver's seat belt buckle switch, front passenger occupant clas-
sification system (ECU and sensors), “AIR BAG ON” and “AIR BAG OFF”
indicator lights, front passenger's seat belt buckle switch, seat belt preten-
sioners, airbags, interconnecting wiring and power sources. (P. 3 5 )

■Front passenger detection sensor, passenger seat belt reminder and
warning buzzer
●If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■If the malfunction indicator lamp comes on while driving
