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 Toy-

When the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 379, 394
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
Check the tire inflation pressure and adjust to the appropriate level.
If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
The tire pressure warning light may come on due to natural causes
(vehicles with a tire pressure warning system)

When trouble arises
When a tire is replaced with a spare tire (vehicles with a tire pressure
warning system)
The spare tire is not equipped with a tire pressure warning valve and trans-
mitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare
tire with the repaired tire and adjust the tire inflation pressure. The tire pres-
sure warning light will go off after a few minutes.
If the tire pressure warning system is not functioning (vehicles with a
tire pressure warning system)
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
If tires not equipped with 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
If the tire inflation pressure is 500 kPa (5.1 kgf/cm
2 or bar, 73 psi) or higher
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
If electronic devices or facilities using similar radio wave frequencies are
nearby
If a radio set at a similar frequency is in use in the vehicle
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 non-genuine Toyota wheels are used (Even if you use Toyota wheels, the
tire pressure warning system may not work properly with some types of
tires.)
If tire chains are used
If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1 min-
ute when the power switch is turned on, have it checked by any authorized

WARNING
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.
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 dealer or repairer, or another duly qualified and
equipped professional.
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
To ensure the tire pressure warning system operates properly (vehi-
cles with a tire pressure warning system)
Do not install tires with different specifications or makers, as the tire pres-
sure warning system may not operate properly.
