*1: Driver’s seat belt reminder:
The driver’s seat belt buzzer sounds to alert the driver 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.
*2: 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/or front passenger that their seat belts are 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.
Front passenger detection sensor and front 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 front pas-
senger is not sitting in the seat.
If a cushion is placed on the seat, the sensor may not detect a front pas-
senger, and the warning light may not operate properly.
Electric power steering system warning light
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on.
If the malfunction indicator lamp comes on while driving
For some models, the malfunction indicator lamp will come on if the fuel tank
becomes completely 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
professional, as soon as possible.
CAUTION
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.

CAUTION
If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
Never attempt to remove the key, as doing so will lock the steering wheel.
