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.

Overheating
If you observe the following, your vehicle may be overheating:
The high engine coolant temperature warning light flashes or comes on
or a loss of power is experienced.
Steam comes out from under the hood.
CAUTION
To prevent an accident or injury when inspecting under the hood of
your vehicle
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
Keep hands and clothing away from the fan and drive belt while the engine
is running.
Do not loosen the radiator cap, or the coolant reservoir cap while the
engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.

CAUTION
To prevent an accident or injury when inspecting under the hood of
your vehicle
If steam is seen coming from under the hood, do not open the hood until

ate. Do not touch or approach the rotating parts of the belt or fan. Doing so
may lead to fingers, clothes or tools getting caught, resulting in injury.

tor are hot.
Serious injuries, such as burns, may result from hot coolant and steam
released under pressure.

The high strength drive belt is used for the generator side drive belt. When
replacing the drive belt, use Toyota genuine drive belt or equivalent high
strength drive belt. If the high strength drive belt is not used, durability of the

with Aramid core which has higher strength compared to usually available
belts with PET or PEN core.
