When trouble arises
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural caus es such as
natural air leaks or tire inflation pressure 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 (if equipped)
Vehicles with full-size spare tire: The spare tire is also equi pped with a tire
pressure warning valve and transmitter. The tire pressure warni ng 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 t he 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 warni ng light will go off
after a few minutes.
Vehicles with compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and transmitter. If a tire goes f lat, the tire pres-
sure 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

WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any a uthorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. The
vehicle will become extremely unstable during braking, and the ABS system
may fail, which could cause an accident resulting in death or s erious injury.
■ When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steerin g is
restricted. When the light comes on red, the assist to the powe r steering is
lost and handling operations of the steering wheel become extre mely
heavy. When steering wheel operations are heavier than usual, g rip the
steering wheel firmly and operate it using more force than usua l.
■ 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 infla-
tion pressure immediately.
● Vehicles with spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that y ou have a flat
tire. Check the tires. If a tire is flat, change it with the sp are tire and have
the flat tire repaired by the nearest any authorized Toyota ret ailer or Toyota
authorized repairer, or any reliable repairer.
● Vehicles with emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after ti re inflation pressure adjustment, it is proba-
ble that you have a flat tire. Check the tires. If a tire is fl at, repair the flat tire
by using emergency tire puncture repair kit. ( P. 697)
● 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.
