■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily 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
First check the following:
●Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing 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 tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).

■If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters 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 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(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

CAUTION
■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, repair the flat tire by using emergency tire puncture
repair kit.
●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.
■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 differ-
ent 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.)

CAUTION
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure 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 efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).

system) malfunction indicator to indicate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire punc-
ture repair kit. (The kit contains a bottle of sealant. The sealant
can be used only once to temporarily repair one tire without
removing the nail or screw from the tire.) After temporarily repair-
ing the tire with the kit, have the tire repaired or replaced by your
To y o ta d e a l e r.
■Before repairing the tire
●St op the veh i cle in a safe place on a hard, flat surface.
●Set the parking brake.
●Shift the shift position to P.
●St op the hyb rid system.
●Turn on the emergency flashers.

Check the specified tire inflation pressure.
Tire inflation pressure is specified on the label on the driver’s side
pillar as shown. (oP. 6 2 7 )
Start the hybrid system. (oP. 2 4 2 )
To i n j e c t t h e s e a l a n t a n d i n f l a t e
the tire, turn the compressor
switch on.

Inflate the tire until the specified
air pressure is reached.
The sealant will be injected and
the pressure will spike to 44 psi
(300 kPa, 3.1 kgf/cm2 or bar) or
58 psi (400 kPa, 4.1 kgf/cm2 or
bar), and then gradually
decrease.
The air pressure gauge will dis-
play the actual tire inflation
pressure about 1 minute (15
minutes at low temperature)
after the switch is turned on.
Inject to specified air pressure.
•Turn the compressor switch
off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the specified
tire inflation pressure is
reached.

•If the tire inflation pressure is
still lower than the specified
point after inflation for 10
minutes (40 minutes at low
temperature) with the switch
on, the tire is too damaged to
be repaired. Turn the com-
pressor switch off and con-
tact your Toyota dealer.
•If the tire inflation pressure
exceeds the specified air
pressure, let out some air to
adjust the tire inflation pres-
sure. (oP. 5 9 0 , 6 2 7 )
With the compressor switch off, disconnect the hose from the
valve on the tire and then pull out the power plug from the
power outlet socket.
Some sealant may leak when the hose is removed.
Install the valve cap onto the valve of the emergency repaired
tire.
