Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least
once a month.
Do not forget to check the spare.■ Inspection and adjustment procedure
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the graduations of the gauge.
If the tire inflation pressure is not within the recommended
levels, adjust the pressure.
If you add too much air, pres s the center of the valve to
lower.
After completing the tire inflation pressure measurement
and adjustment, apply soapy water to the valve and check
for leakage.
Reinstall the tire valve cap.STEP 1

Maintenance and care ■
Effects of incorrect tire inflation pressure
Driving with incorrect ti re inflation pressure ma y result in the following:●
Reduced fuel economy●
Reduced driving comfort and poor handling●
Reduced tire life due to wear●
Reduced safety●
Damage to the drive train
If a tire needs frequent re filling, have it checked by your Toyota dealer.■
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following: ●
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●
Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its
appearance.
●
It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pressure after
driving.
●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

WARNING■
Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury: ●
Excessive wear●
Uneven wear●
Poor handling●
Possibility of blowouts resulting from overheated tires●
Air leaking from between tire and wheel●
Wheel deformation and/or tire damage●
Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE■
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
If a valve cap is not installed, dirt or moisture may ge t into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

When replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves and transmitters that allow the tire pressure warning system to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, the tire pressure warning valves and
transmitters must be installed. ( → P. 271)
WARNING■
When replacing wheels ●
Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in loss of handling control.●
Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
■
When installing the wheel nuts
●
Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts. ●
Be sure to install the wheel nuts with
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death or serious injury.Tapered portion

Maintenance and care NOTICE■
Replacing tire inflation pressure warning valves and transmitters ●
Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.●
Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

: Driver’s seat belt buzzer:
The driver’s seat belt buzzer sounds to alert the driver that his or her seat
belt is not fastened. Once the engine switch is turned to the “ON” position,
the buzzer sounds for 6 seconds. If the vehicle reaches a speed of 12 mph
(20 km/h), the buzzer sounds once. If the seat belt is still unfastened after 24
seconds, the buzzer will sound intermittently for 10 seconds. Then, if the
seat belt is still unfastened, the buzzer will sound in a different tone for 20
more seconds. Tire pressure warning
light
When the light comes on:
Low tire inflation pressure
such as
• Natural causes ( → P. 322)
• Flat tire ( → P. 327) Adjust the tire inflation
pressure to the specified
level.
The light will turn off after
a few minutes. In case the
light does not turn off
even if the tire inflation
pressure is adjusted,
have the system checked
by your Toyota dealer.
When the light comes on
after blinking for approxi-
mately one minute:
Malfunction in the tire pres-
sure warning system
( → P. 323) Have the system checked
by your Toyota dealer.
Automatic transmission
fluid temperature warning
light (if equipped)
Indicates that the auto-
matic transmission fluid
temperature is too high. Stop the vehicle in a safe
place and shift the shift lever
to P.
If the light goes off after a lit-
tle while, the vehicle can be
driven. If the light does not
go off, contact your Toyota
dealer.Warning light Warning light/Details Correction procedure

: Front passenger’s seat belt buzzer:
The front passenger’s seat belt buzzer sounds to alert the front passenger
that his or her seat belt is not fastened. The buzzer sounds once if the vehi-
cle reaches a speed of 12 mph (20 km/h). If the seat belt is still unfastened
after 24 seconds, the buzzer will sound intermittently for 10 seconds. Then,
if the seat belt is still unfastened, the buzzer will sound in a different tone for
20 more seconds.
■ Front passenger detection sensor and passenger seat belt reminder
and warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and warning
buzzer to sound, even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
■
The tire pressure warning light ma y turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflat ion pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■
When a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning
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 re paired tire and adjust the tire infla-
tion pressure. The tire pressure wa rning light will go off after a few min-
utes.
