■ Initializing the tire pressure warning system (vehicles with a tire pres-
sure warning system)
Initialize the system with the tire inflation pressure adjusted to the specified
level.
■ If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
■ Situations in which the tire pressure warning system may not operate
properly (vehicles with a tire pressure warning system)
● In the following cases, the tire pressure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire t hat is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheels without the tire pressure warning valves and transmitters are
used.
• If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
● Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
• When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
● When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
● When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

■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 passenger,
and the warning light may not operate properly.
■ Warning light operations for unfastened rear passenger seat belts
● When opening and closing the rear door, the warning light comes on for
approximately 34 seconds.
● When any of the rear seat belts are unfastened, the warning light comes on.
When the rear doors are opened and closed while the warning light is on,
the warning light will turn off after approximately 34 seconds.
■ 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 imme-
diately. The malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer as soon
as possible.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
■ Electric power steering system warning light (warning buzzer)
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 sounds.
■ Engine oil change reminder light comes on (diesel engine only)
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 illumi-
nated when you have driven less than 40000 km (25000 miles) based on a
usage or driving condition.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized
Toyota retailer or Toyota authorized r epairer, or any reliable repairer. The
vehicle will become extremely unstable during braking, and the ABS system
may fail, which could cause an accident resulting in death or serious injury.
■ 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.
■ If the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● Vehicles with spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that you have a flat
tire. Check the tires. If a tire is flat, change it with the spare tire and have
the flat tire repaired by the nearest authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
● Vehicles with emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after tire inflat ion pressure adjustment, it is proba-
ble that you have a flat tire. Check the tire s. If a tire is flat, repair the flat tire
by using emergency tire puncture repair kit. ( P. 592)
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur (vehicles with a tire
pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■ If the fuel filter warning light comes on (diesel engine only)
Never drive the vehicle with the warning light on. Continued driving with
water accumulated in the fuel filter will damage the fuel injection pump.
■ To ensure the tire pressure warning system operates properly (vehi-
cles with a tire pressure warning system)
Do not install tires with different specif ications or makers, as the tire pres-
sure warning system may not operate properly.
