■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes
insufficient or the voltage temporar-
ily drops, the electric power steering
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.471
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 1 minute then stays on
There may be a malfunction in the
tire pressure warning system. Have
the vehicle inspected by your Toyota
dealer immediately.
If the tire pressure warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation 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 specified level and perform
initialization. ( P.424)
If the warning light does not turn off
several minutes afte r the initializa-
tion has been performed, have the
vehicle inspected by your Toyota
dealer immediately.
■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
pressure changes caused by tem- perature. In this ca
se, adjusting the
tire inflation pressure will turn off the
warning ligh t (after a few minutes).
■When a tire is replaced with a
spare tire
Vehicles with a co mpact spare tire:
The compact spare tire is not
equipped with a tire pressure warn-
ing valve and tran smitter. 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 pres-
sure warning light will go off after a
few minutes.
Vehicles with a full-size spare tire:
The spare tire is also equipped with
a tire pressure warning valve and
transmitter. The tire pressure warn-
ing light will turn on if the tire infla-
tion pressure of the spare tire is low.
If a tire goes flat, the tire pressure
warning light will no t 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 infla-
tion pressure. The tire pressure
warning light will go off after a few
minutes.
■Conditions that the tire pres-
sure warning system may not
function properly
 P.420
WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your Toy-
ota dealer.

extremely unstable during brak-
ing, and the ABS system may fail,
which could cause an accident
resulting in death o r serious injury.
