drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P. 3 2 3
If none of the tires are punctured: Turn the engine switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
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.280)
■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).

cautions. 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.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.

kit cannot be used to repair the
tire. ( P.324)
After temporarily repairing the
tire with the kit, have the tire
repaired or replaced by any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer. Repairs
conducted using the emer-
gency tire puncture repair kit
are only a temporary measure.
Have the tire repaired and
replaced as soon as possible.
WARNING
■If you have 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, which could
