If the malfunction indicator la mp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■ Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient of the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. 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 pressu re warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function
properly
P. 3 5 9
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the power switch is turn ed to ON mode, have it checked by
your Toyota dealer.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extrem ely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steerin g system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavie r than usual when operating, hold
firmly and operate using more force than usual.
■
If the tire pressure warning light comes on
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
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, change it with th e spare tire and have the flat tire
repaired by the nearest Toyota dealer.
●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
The tire pressure warning system may not activate immediately.

WARNING
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pre ssure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s hand ling and stopping ability.
Please note that the TPMS (tire pres sure warning system) is not a sub-
stitute for proper ti re maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumina tion of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the lo w tire pressure telltale (tire pressure
warning light). When the system dete cts a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue up on subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure as intended.

WARNING
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different sp ecifications or makers, as the tire
pressure warning system may not operate properly.

tions. (For example, when driving up a long steep hill.)
■ If “Maintenance Required for Hybr id Battery Cooling Parts at Your
Dealer” is shown.
The filter may be clogged, the air intake vent may be blocked or there may be
a gap in the duct. Have maintenance performed on the hybrid battery (trac-
tion battery) cooling component at your Toyota dealer.
If a war ning mess age is displayed
The multi-information display shows warnings of system mal-
functions, incorrectly performed operations, messages that indi-
cate a need for maintenance and reminder messages. When a
message is shown, perform th e correction procedure appropri-
ate to the message.

●Stop the vehicle on a hard, flat surface.
● Set the parking brake.
● Shift the shift lever to P.
● Stop the hybrid system.
● Turn on the emergency flashers. ( P. 390)
If you have a flat tire

WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a fl at tire can damage the tire and the
wheel beyond repair, which could result in an accident.
