Passenger detection sensor and passenger seat belt reminder
If luggage is placed on a passenger seat, the passenger detection sensor
may cause the warning light to flash even if a passenger 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 warning light (warning buzzer)
Except hybrid vehicle: When the battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
Hybrid vehicle: When the 12-volt battery charge becomes insufficient or the
voltage temporarily drops, the electric power steering system warning light
may come on and the warning buzzer may sound.
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 profes-
sional as soon as possible.
If the engine oil change reminder light flashes (diesel engine with a
DPF system)
Repeated short trips and/or low-speed driving may cause the oil to degrade
sooner than usual, regardless of the actual distance driven. If this happens,
the engine oil change reminder light will flash.
Engine oil change reminder light comes on (diesel engine only)
Vehicles without a DPF system:
Replace the engine oil and oil filter when the engine oil change reminder
light does not come on even if you have driven over 40000 km (25000 miles)
after the engine oil was changed.
There is a possibility that the engine oil change reminder light has been illu-
minated when you have driven less than 40000 km (25000 miles) based on
a usage or driving condition.
