Maintenance and care
Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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 1.5 km or 1 mile, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
Do not bleed or reduce tire inflation pressure after driving. It is normal for
the tire inflation pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced. Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 621)

458 4-3. Do-it-yourself maintenance
CAUTION
Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions may
occur and result in an accident causing death or serious injury.
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts resulting from overheated tires
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road hazards
NOTICE
When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or moisture could get into the valve and cause
air leakage, which could result in an accident. If the caps have been lost,
replace them as soon as possible.

460 4-3. Do-it-yourself maintenance
When removing the wheel ornament (vehicles with the wheel cap clip)
When replacing wheels (vehicles with the tire pressure warning sys-
tem)
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters (except for spare tire) that allow the tire pressure warning
system to provide advance warning in the event of a loss in tire inflation
pressure. Whenever wheels are replaced, tire pressure warning valves and
transmitters must be installed.
(P. 444)
CAUTION
When replacing wheels
Observe the following precautions to reduce the risk of death or serious
injury.
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 tube-
less tire.
When installing the wheel nuts
Remove the wheel ornament using the
wheel cap clip.
Be sure to install the wheel nuts with
the tapered ends facing inward. Install-
ing the nuts with the tapered ends fac-
ing 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

Maintenance and care
CAUTION
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 acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
NOTICE
Replacing tire pressure warning valves and transmitters (vehicles with
the tire pressure warning system)
Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
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.

Front passenger detection sensor and passenger seat belt reminder
If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger 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 (vehicles with a tire
pressure warning light system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 536, 552
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
Check the tire inflation pressure and adjust to the appropriate level.
If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.

520 5-2. Steps to take in an emergency
The tire pressure warning light may come on due to natural causes
(vehicles with a tire pressure warning light 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 temperature.
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 (vehicles with a tire pressure
warning light system)
The spare tire is not equipped with a tire pressure warning valve and trans-
mitter. 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.
If the tire pressure warning system is not functioning (vehicles with a
tire pressure warning light system)
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
If tires not equipped with tire pressure warning valves and transmitters
are used
If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer
If the tire inflation pressure is 380 kPa (3.9 kgf/cm
2 or bar, 55 psi) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
If electronic devices or facilities using similar radio wave frequencies are
nearby
If a radio set at a similar frequency is in use in the vehicle
If a window tint that affects the radio wave signals is installed
If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings

521 5-2. Steps to take in an emergency
When trouble arises
If non-genuine Toyota wheels are used (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
If tire chains are used
If the tire pressure warning light frequently comes on after blinking for
1 minute (vehicles with a tire pressure warning light system)
If the tire pressure warning light frequently comes on after blinking for 1 min-
ute when the engine switch (vehicles without smart entry & start system) or
the “ENGINE START STOP” switch (vehicles with smart entry & start sys-
tem) is turned on, have it checked by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
CAUTION
If the tire pressure warning light comes on (vehicles with a tire pres-
sure warning light system)
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 infla-
tion 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 a tire
is flat, change it with the spare tire and have the flat tire repaired by the
nearest any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
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 (vehicles with a tire
pressure warning light system)
The tire pressure warning system may not activate immediately.
