tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have
elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization.
( P.483)
■The tire pressure warning light may
come on due to natural causes (vehicles with a tire pressure warn-
ing system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres-
sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light
(after a few minutes).
■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 transmitter.
If a tire goes flat, the tire pressure warn-
ing 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 pr essure warning light
will go off after a few minutes.
■Conditions that the tire pressure
warning system may not function properly (vehicles with a tire pres-
sure warning system)

WA R N I N G
■If both the ABS and the brake
system warning lights remain on
Stop your vehicle in a safe place immediately and contact any author-
ized Toyota retailer or Toyota author-
ized repairer, or any reliable repairer. The vehicle will become extremely
unstable during br aking, and the ABS
system may fail, which could cause
an accident resulting in death or seri- ous injury.
■When the electric power steer-ing system warning light comes
on
When the light comes on yellow, the assist to the power steering is
restricted. When th e light comes on
red, the assist to the power steering is lost and handling operations of the
steering wheel become extremely
heavy. When steering wheel operations are
heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on (vehicles with a tire
pressure warning system)
Be sure to observe the following pre- cautions.
Failure to do so could cause a loss of
vehicle control and re sult in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.

■Warning messages
The warning messages explained below
may differ from the actual messages
according to operation conditions and vehicle specifications.
■Warning buzzer
A buzzer may sound when a message is
displayed. The buzzer may not be audible if the
vehicle is in a noisy location or if the
audio system volume is high.
■If “Engine Oil Level Low Add or Replace” is displayed
The engine oil level is low. Check the
WA R N I N G
●Vehicles with a compact spare tire
and full-size 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 any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture repair kit: 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, 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 leak-age should occur (vehicles with
a tire pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warn-
ing system operates properly
(vehicles with a tire pressure warning system)
Do not install tires with different speci-
fications or makers, as the tire pres- sure warning system may not operate
properly.
If a war ning message is
displayed
The multi-information display
shows warnings for system
malfunctions and incorrectly
performed operations, and
messages that indicate a need
for maintenance. When a mes-
sage is displayed, perform the
appropriate corrective action
for the message.
If a warning message is dis-
played again after the appro-
priate actions have been
performed, contact any author-
ized Toyota retailer or Toyota
authorized repairer, or any reli-
able repairer.
Additionally, if a warning light
comes on or flashes at the
same time that a warning mes-
sage is displayed, take the
appropriate corrective action
for the warning light. ( P.511)

When trouble arises
WA R N I N G
■When fixing the flat tire
●Stop your vehicle in a safe and flat
area.
●Do not touch the wheels or the area
around the brakes immediately after the vehicle has been driven.
After the vehicle has been driven,
the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands,
feet or other body parts may result
in burns.
●Connect the valve and hose
securely with the tire installed on the vehicle. If the hose is not prop-
erly connected to the valve, air
leakage may occur as sealant may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk
that the hose will move abruptly due
to air pressure.
●After inflation of the tire has com-
pleted, the sealant may splatter when the hose is disconnected or
some air is let out of the tire.
●Follow the operation procedure to
repair the tire. If the procedures not
followed, the sealant may spray out.
●Keep back from the tire while it is
being repaired, as there is a chance of it bursting while the repair opera-
tion is being performed. If you
notice any cracks or deformation of
the tire, turn off (type A) or (off)
(type B) the compressor switch and
stop the repair operation immedi- ately.
●The repair kit may overheat if oper-ated for a long period of time. Do
not operate the repair kit continu-
ously for more than 40 minutes.
●Parts of the repair kit become hot during operation. Be careful when
handling the repair kit during and
after operation. Do not touch the metal part around the connecting
area between the bottle and com-
pressor. It will be extremely hot.
●Do not attach the vehicle speed
warning sticker to an area other than the one indicated. If the sticker
is attached to an area where an
SRS airbag is located, such as the pad of the steering wheel, it may
prevent the SRS airbag from oper-
ating properly.
●To avoid risk of burst or severe
leakage, do not drop or damage the bottle. Visually inspect the bottle
before use. Do not use a bottle with
shock, crack, scratch, leakage or any other damage. In such case,
immediately replace.
■Driving to spread the liquid seal-
ant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of
vehicle control and cause death or serious injury.
●Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
●If the vehicle does not drive straight
or you feel a pull through the steer-
ing wheel, stop the vehicle and check the following.
• Tire condition. The tire may have
separated from the wheel.
• Tire inflation pressure. If the tire
inflation pressure is 130 kPa (1.3
kgf/cm2 or bar, 19 psi) or less, the tire may be severely damaged.
