onds. Then, if the seat belt is still unf astened, the buzzer will sound in a dif-
ferent tone for 90 more seconds.
■Rear passengers’ seat belt reminder lights (warning buzzer)*
*: Rear passengers’ seat belt warning buzzer:
The rear passengers’ seat belt warning buzzer sounds to alert the rear pas-
sengers that his or her seat belt is not fastened. If any rear seat belt is fas-
tened and then unfastened, the rear passengers' seat belt reminder light
will illuminate for that seat. While illumi nated, if the vehicle reaches a speed
of 12 mph (20 km/h), th e buzzer will sound once. If the seat belt is still
unfastened after 24 seconds, the buzzer will sound intermittently for 6 sec-
onds. Then, if the seat belt is still unf astened, the buzzer will sound in a dif-
ferent tone for 30 more seconds.

■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).

When trouble arises
 Stop the vehicle in a safe
place on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P (con- tinuously variable transmis-
sion) or N (manual
transmission).
 Stop the engine.
 Turn on the emergency flash-
ers.
 Check the degree of the tire
damage.
A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a nail or screw pass-
ing through the tire tread.
• Do not remove the nail or screw from the tire. Removing
the object may widen the
opening and make emer-
gency repair with the repair kit
impossible.
• To avoid sealant leakage, move the vehicle until the
area of the puncture, if
known, is positioned at the
top of the tire.
■A flat tire that cannot be
repaired with the emergency
tire puncture repair kit
In the following cases, the tire can-
not be repaired with the emergency
tire puncture repair kit. Contact your
Toyota dealer.
If you have a flat tire
(vehicles without
spare tire)
Your vehicle is not equipped
with a spare tire, but instead
is equipped with an emer-
gency tire puncture repair
kit.
A puncture caused by a nail
or screw passing through
the tire tread can be
repaired temporarily using
the emergency tire puncture
repair kit. (The kit contains a
bottle of sealant. The seal-
ant can be used only once
to temporarily repair one
tire without removing the
nail or screw from the tire.)
After temporarily repairing
the tire with the kit, have the
tire repaired or replaced by
your Toyota dealer.
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 result in an accident.

12 Start the engine.
13 To inject the sealant and
inflate the tire, turn the com-
pressor switch on. 14Inflate the tire until the speci-
fied air pressure is reached.
The sealant will be injected
and the pressure will spike to
between 44 psi (300 kPa, 3.0
kgf/cm
2 or bar) and 58 psi
(400 kPa, 4.0 kgf/cm
2 or bar),
then gradually decrease.
The air pressure gauge will
display the actual tire inflation
pressure about 1 to 5 min-
utes after the switch is turned
on.
Turn the compressor switch off and
then check the tire inflation pres-
sure. Being careful not to over
inflate, check and repeat the infla-
tion procedure until the specified
tire inflation pressure is reached.
The tire can be inflated for about 5
to 20 minutes (depending on the
outside temperature). If the tire
inflation pressure is still lower than
the specified point after inflation for
25 minutes, the tire is too damaged

to be repaired. Turn the compres-
sor switch off and contact your Toy-
ota dealer.
If the tire inflation pressure exceeds
the specified air pressure, let out
some air to adjust the tire inflation
pressure. ( P.500, 531)
15 With the compressor switch
off, disconnect the hose from
the valve on the tire and then
pull out the power plug from
the power outlet socket.
Some sealant may leak when the
hose is removed.
16 Install the valve cap onto the
valve of the emergency
repaired tire.
17 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.
18 Temporarily store the bottle
in the trunk while it is con-
nected to the compressor.
19 To spread the liquid sealant
evenly within the tire, imme-
diately drive safely for about
3 miles (5 km) below 50 mph
(80 km/h).
20 After driving, stop your vehi-
cle in a safe place on a hard, flat surface and reconnect
the repair kit.
Remove the air release cap from
the hose before reconnecting the
hose.
21Turn the compressor switch
on and wait for several sec-
onds, then turn it off. Check
the tire inflation pressure.
If the tire inflation pressure is
under 19 psi (130 kPa, 1.3
kgf/cm
2 or bar): The puncture
cannot be repaired. Contact
your Toyota dealer.
If the tire inflation pressure is
19 psi (130 kPa, 1.3 kgf/cm
2
or bar) or higher, but less
than the specified air pres-
sure: Proceed to step 22.
If the tire inflation pressure is
the specified air pressure
