*: Driver's and front passenger’s seat belt reminders:
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 for 30 seconds after the vehicle has reached a speed of at least 20
km/h (12 mph). Then, if the seat belt is still unfastened, the buzzer will sound
in a different tone for 90 more seconds.
Master warning light
A buzzer sounds and the
warning light comes on
and flashes to indicate that
the master warning system
has detected a malfunc-
tion.P. 436
If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empty, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional, as soon as possible.
Front passenger detection sensor and passenger seat belt reminder
If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.
