sure warning system may not
function properly
 P. 4 7 4
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.
■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 inflation pressure immedi-
ately.
●If the tire pressure warning light
comes on even after tire infla-
tion pressure 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
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
Each tire, includi ng 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.)

When trouble arises
WARNING
As an added safe ty feature, your
vehicle has been equipped with a
tire pressure m onitoring system
(TPMS-tire pressure 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 pres-
sure warning light) illuminates,
you should stop and check your
tires as soon as possible, and
inflate them to the proper pres-
sure. Driving on a significantly
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 pro per tire mainte-
nance, and it is the driver’s
responsibility to maintain correct
tire pressure, even if under-infla-
tion has not reach ed the level to
trigger illumination of the TPMS
low tire pressure telltale (tire pres-
sure warning light).
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 te lltale will flash
for approximately one minute and
then remain continuously 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 ab le 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
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.

5Remove the valve cap from
the valve of the punctured
tire.
6 Extend the hose. Remove
the air release cap from the
hose.
You will use the air release cap
again. Therefore keep it in a safe
place.
7Connect the hose to the
valve.
Screw the end of the hose clock-
wise as far as possible.
8Make sure that the compres-
sor switch is off.
9 Connect the power plug to
the power outlet socket.
( P.428)
10Attach the sticker provided with the tire puncture repair
kit to a position easily seen
from the driver’s seat.

13 To inject the sealant and
inflate the tire, turn the com-
pressor switch on.
14 Inflate the tire until the rec-
ommended 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
pressure. Being careful not to
over inflate, check and repeat the
inflation procedure until the speci-
fied tire inflation pressure is
reached.
• The tire can be in flated for about
5 to 20 minutes (depending on
the outside temperature). If the
tire inflation press ure is still lower
than the specified point after infla-
tion for 25 minutes, the tire is too
damaged to be repaired. Turn the
compressor switch off and con-
tact your Toyota dealer.
• If the tire inflation pressure exceeds the spec ified air pres-
sure, let out some air to adjust the
tire inflation pressure. ( P.535)
15With the compressor switch
off, pull out the power plug
from the power outlet socket
and then disconnect the hose
from the valve on the tire.
Some sealant may leak when the
hose is removed.
16Install the valve cap onto the valve of the emergency
repaired tire.
17Attach the air release cap to the end of the hose.
If the air release cap is not
attached, the sealant may leak and

y get dirty.
18Temporarily store the bottle
in the luggage compartment
while it is connected 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.
21 Turn 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
( P.555): Proceed to
step 23.
22Turn 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.
23Attach the air release cap to the end of the hose.
If the air release cap is not
attached, the sealant may leak and
