■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 (vehicles with a
tire pressure warning system)
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.493, 503
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 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.450)
■The tire pressure warning light
may come on due to natural
causes (vehicles with a tire
pressure warning system)
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 case, adjusting the
tire inflation pressu re will turn off the
warning light (after a few minutes).
■When a tire is replaced with a
spare tire (vehicles with a tire
pressure warning system)
Vehicles with a compact spare tire:
The compact spare tire is not
equipped with a tire pressure warn-
ing valve and transmitter. 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.
■Conditions that the tire pres-
sure warning system may not
function properly (vehicles with
a tire pressure warning system)
 P.447
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.
The vehicle will become
extremely unstable during brak-
ing, and the ABS system may fail,
which could cause an accident
resulting in death or serious injury.
■When the electric power
steering system warning light
comes on
When the light comes on yellow,
the assist to the power steering is
restricted. When the light comes
on red, the assist to the power
steering is lost and handling oper-
ations 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.

When trouble arises
WARNING
■If the tire pressure warning
light comes on (vehicles with
a tire pressure warning sys-
tem)
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 inflation pressure immedi-
ately.
●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 Toyota dealer.
●Vehicles with emergency tire
puncture repair kit: If the tire
pressure warning light comes
on even after tire inflation pres-
sure 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
leakage should occur (vehi-
cles with a tire pressure warn-
ing system)
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
Each tire, includ ing the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label (tire and
load information label). (If your
vehicle has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS-tire pres sure warning sys-
tem) that illuminates a low tire
pressure telltale (tire pressure
warning light) when one or more
of your tires is significantly
under-inflated. Accordingly, when
the low tire pressure telltale (tire
pressure warning light) illumi-
nates, you should stop and check
your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a signifi-
cantly under-inflated tire causes
the tire to overheat and can lead
to tire failure. Under-inflation also
reduces fuel efficiency and tire
tread life, and may affect the vehi-
cle’s handling and stopping ability.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for proper tire mainte-
nance, and it is the driver’s
responsibility to maintain correct
tire pressure, even if under-infla-
tion has not reached the level to
trigger illumination of the TPMS
low tire pressure telltale (tire pres-
sure warning light).

■Warning messages
The warning messages explained
below may differ from the actual
messages according to operation
conditions and vehicle specifica-
tions.
■Warning buzzer
A buzzer may sound when a mes-
sage is displayed.
The buzzer may not be audible if the
vehicle is in a noisy location or if the
audio system volume is high.
■If “Engine Oil Level Low Add or
Replace” is displayed
The engine oil level is low. Check
WARNING
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not operating properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash
for approximately one minute and
then remain cont inuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the sys-
tem may not be able to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly (vehicles with a tire
pressure warning system)
Do not install tires with different
specifications or makers, as the
tire pressure wa rning system may
not operate properly.
If a war ning message
is displayed
The multi-information dis-
play shows warnings for
system malfunctions and
incorrectly performed oper-
ations, and messages that
indicate a need for mainte-
nance. When a message is
displayed, perform the
appropriate corrective
action for the message.
If a warning message is dis-
played again after the
appropriate actions have
been performed, contact
your Toyota dealer.
Additionally, if a warning
light comes on or flashes at
the same time that a warn-
ing message is displayed,
take the appropriate correc-
tive action for the warning
light. ( P.481)

22 Turn the compressor switch
on to inflate the tire until the
specified air pressure is
reached. Drive for about 3
miles (5 km) and then per-
form step 20.
23 Attach the air release cap to
the end of the hose.
If the air release cap is not
attached, the sealant may leak and
the vehicle may get dirty.
24 Store the bottle in the trunk
while it is connected to the
compressor.
25 Taking precautions to avoid
sudden braking, sudden
acceleration and sharp turns,
drive carefully at under 50
mph (80 km/h) to the nearest
Toyota dealer that is less
than 62 miles (100 km) away
for tire repair or replacement.
When having the tire repaired or
replaced, make sure to tell the Toy-
ota dealer that the sealant is
injected.
■If the tire is inflated to more
than the specified air pressure
1 Disconnect the hose from the
valve. 2
Install the air release cap to the
end of the hose and push the
protrusion on the air release cap
into the tire valve to let some air
out.
3 Disconnect the hose from the
valve, remove the air release cap
from the hose and then recon-
nect the hose.
4 Turn the compress or switch on
and wait for se veral seconds,
and then turn it off. Check that
the air pressure indicator shows
the specified air pressure.
(  P.531)
If the air pressure is under the des-
ignated pressure, turn the compres-
sor switch on again and repeat the
inflation procedure until the speci-
fied air pressure is reached.
■The valve of a tire that has been
repaired (vehicles without a tire
pressure warning system)
After a tire is repaired with the emer-
gency tire puncture repair kit, the
valve should be replaced.
■After a tire is repaired with the
emergency tire puncture repair
kit (vehicles with a tire pressure
warning system)
●The tire pressure warning valve
and transmitter should be
replaced.
●Even if the tire in flation pressure is
at the recommended level, the tire
pressure warning light may come
on/flash.
