For some models, the malfunction indi- cator lamp will come on if the fuel tank
becomes completely empty. If the fuel tank is empty, refuel the vehicle immedi-ately. The malfunction indicator lamp will
go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as possi-ble.
■Electric power steering system
warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tem-
porarily drops, the electric power steer- ing system 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.386, 397
If none of the tires are punctured:
Turn the power 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.337)
■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-

If you have a flat tire
(vehicles with an emer-
gency tire puncture
repair kit)
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily using the emergency tire
puncture 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.)
Depending on the damage, this
kit cannot be used to repair the
tire. ( P.387)
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.
