If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-
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.442)
■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 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 compact spare tire: The compact 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 pressure
warning light will go off after a few min- utes.
Vehicles with a full-size spare tire: The
spare tire is also equipped with a tire pressure warning valve and transmitter.
The tire pressure warning light will turn
on if the tire inflation pressure of the spare tire is low. 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
pressure warning light will go off after a few minutes.

■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
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.

WA R N I N G
●Vehicles with a compact 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 author-
ized 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
The tire pressure warning system
may not activate immediately.
NOTICE
■To ensure the tire pressure warn- ing system operates properly
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.471)

4968-2. Steps to take in an emergency
2 Check that the air pressure indicator
shows the specified air pressure.
If the air pressure is under the desig-
nated pressure, turn the compressor
switch on (type A) or (on) (type B)
again and repeat the inflation procedure
until the specified air pressure is
reached.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pres-
sure warning light may come on/flash.
WA R N I N G
■Do not drive the vehicle with a
flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a
flat tire can damage the tire and the wheel beyond repair.
Driving with a flat tire may cause a cir-
cumferential groove on the side wall. In such a case, t he tire may explode
when using a repair kit.
■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.
