Tires and loading on yourTo y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 411 and 487.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
Perchlorate Material
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.

(k) “VSC” Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system or traction control system.
The light will come on when the ignition
key is turned to “ON” and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
Tw o −wheel drive models only—The “TRAC
OFF” indicator light will come on when the
“VSC” warning light comes on even if the
“TRAC OFF” switch is not pushed. (l) Low Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (without the
spare tire) is low. The light comes on
when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all four tires is as specified on the tire
and loading information label. (See
“Checking tire inflation pressure” on page
487 in Section 7
−2.) The light should go
off 3 to 6 minutes after the tire pressure
is adjusted.
If the warning light comes on after blink-
ing for 1 minute, the tire pressure warning
system may be malfunctioning. Contact
your Toyota dealer.
For details, see “Tire pressure warning
system” on page 214 in Section 1 −7. (m) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” on page 503 in
Section 7 −3.)
(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 8000 km (5000
miles), the light will come on after the
ignition key is turned to “ON” position.
The light will remain on thereafter.

The tire pressure warning light comes on
when the ignition key is turned to the
“ON” position and goes off after a few
seconds. This means the tire pressure
warning light is operating properly. If the
tire inflation pressure becomes low, the
light comes on again. In this case, adjust-
ing the tire inflation pressure will turn off
the light after several minutes. If the light
comes on after blinking for 1 minute, the
tire pressure warning system is not work-
ing properly.Indicator

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Vehicles with runflat tires:
Decelerate to the lowest appropriate
speed as soon as possible. Do not
drive over 90 km/h (55 mph).
Check and adjust the tire inflation
pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Have the
tire replaced by the nearest Toyota
dealer.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
Vehicles with standard tires:
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 inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.

The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after several minutes.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light.
The compact spare tire is not equipped
with the tire pressure warning valve and
transmitter. If a tire goes flat, the warning
light will not turn off even though the flat
tire is replaced with the spare tire. Re-
place the spare tire with the repaired tire
and adjust the proper tire inflation pressur-
e. The tire pressure warning light will turn
off after several minutes.CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer 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 information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. 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 pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.

Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).NOTICE
 Do not use liquid sealants for a flat
tire as tire pressure warning valve
and transmitter will be damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure warning valves and trans-
mitters will be affected by the
installation or removal of tires.
IF THE TIRE PRESSURE WARNING
LIGHT COMES ON AFTER BLINKING
FOR 1 MINUTE...
If the tire pressure warning light comes
on after blinking for 1 minute when the
ignition key is turned to the “ON” posi-
tion, the tire pressure warning system
is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.

REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered in the tire pressure warning
ECU. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
If the ID code is not registered, the sys-
tem will not work properly. After about 20
min −drive, the tire pressure warning light
comes on after blinking for 1 minute to
indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.
TIRE PRESSURE WARNING RESET
SWITCH
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
