seat.
●If a cushion is placed on the seat,
the sensor may not detect a pas-
senger, and the warning light may
not operate properly.
■SRS warning light
This warning light system monitors
the airbag sensor assembly, front
impact sensors, side impact sensors
(front door), side impact sensors
(front), side impact sensors (rear),
driver’s seat position sensor,
driver’s seat belt buckle switch, front
passenger occupant classification
sensors, “AIR BAG ON” indicator
light, “AIR BAG OFF” indicator light,
front passenger’s seat belt buckle
switch, seat belt pretensioners and
force limiters, airbags, interconnect-
ing wiring and power sources.
(  P.42)
■If the malfunction indicator
lamp comes on while driving
First check the following:
●Is the fuel t ank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go o ff after several
driving trips.
If the light does not go off even after
several trips, contact your Toyota
dealer as soon as possible.
■Electric power steering system
warning light (warning buzzer)
When the 12-volt battery charge
becomes insufficien t or the voltage
temporarily 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.490 If none of the tires are punctured:
Turn the power switch to OFF then
turn it to ON.
Check if the tire pressure warning
light comes on or blinks.
If the tire pressur
e 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 pressur e 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.427)
■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
compact spare tire (vehicles
with compact 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. Replac e the spare tire
with the standard 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
 P.425
WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your
Toyota dealer. The vehicle will
become extremely unstable
during braking, and the ABS sys-
tem 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 con-
trol and result in death or serious
injury.
●Stop your vehicle in a safe
place as soon as possible.
Adjust the tire inflation pressure
immediately.
●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, change it with the spare tire
and have the flat tire repaired by
the nearest Toyota dealer.
●Avoid abrupt maneuvering and
braking. If the vehicle tires dete-
riorate, 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.)

4747-2. Steps to take in an emergency
WARNING
As an added safety 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 abil-
ity.
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 manufacturers
as the tire pressure warning sys-
tem may not operate properly.

4807-2. Steps to take in an emergency
Stop the vehicle in a safe
place on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P.
 Stop the hybrid system.
 Turn on the emergency flash-
ers. ( P.456)
 Disable the power sliding door
system. ( P.148)
 For vehicles with power back
door: Disable the power back
door system. ( P.163)
 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
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 emergency tire puncture
repair kit. A puncture
caused by a nail or screw
passing through the tire
tread can be repaired tem-
porarily using the emer-
gency tire puncture repair
kit. (The kit contains a bottle
of sealant. The sealant can
be used only once to tempo-
rarily repair one tire without
removing the nail or screw
from the tire.) Depending on
the damage condition of the
flat tire, it may not be able to
repaired with the emer-
gency tire puncture repair
kit. (
P.481)
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.
Driving with a flat tire may cause a
circumferential groove on the side
wall.
In such a case, the tire may
explode when using a repair kit.

12 To inject the sealant and
inflate the tire, turn the com-
pressor switch on. 13Inflate 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/cm2 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 compre ssor switch off
and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat the
inflation procedure until the rec-
ommended tire inflation pressure
is reached.

with the switch on, 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 recommended level,
let out some air to adjust the tire
inflation pressure. ( P.487, 523)
14 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.
15 Install the valve cap onto the
valve of the emergency
repaired tire.
16 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 ma y get dirty.
17Temporarily store the bottle
in the trunk while it is con-
nected to the compressor.
18 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). 19After driving, stop your vehi-
cle in a safe place on a hard,
flat surface and reconnect
the compressor.

24 Taking precautions to avoid
sudden braking, sudden
acceleration and sharp turns,
drive carefully at under 50
mph (80 km/h) to your Toyota
dealer that is less than 62
miles (100 km) away for tire
repair or replacement.
Make sure to tell your Toyota
dealer when you have them repair
or replace the tire that sealant is
injected.
■If the tire is i nflated 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.

valve, remove the air release cap
from the hose and then recon-
nect the hose.
4 Turn the compressor switch on
and wait for seve ral seconds,
and then turn it off. Check that
the air pressure indicator shows
the specified air pressure.
If the air pressure is lower than the
designated pressure, turn the com-
pressor switch on again and repeat
the inflation pr ocedure until the
specified air pressure is reached.
■After a tire is re paired with the
emergency tire puncture repair
kit
●The tire pressure warning valve
and transmitter should be
replaced.
●Even if the tire inflation pressure is
at the recommended level, the tire
pressure warning light may come
on/flash.
