■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation
pressure as part of your routine of daily vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is turned to ON. It may
also take a few minutes to display the tire inflation pressure after inflation pressure has been adjusted.
●Tire inflation pressure changes with temperature. The displayed values
may also be different from the values measured using a tire pressure gauge.
■Situations in which the tire pres-
sure warning system may not oper- ate properly
●In the following cases, the tire pres-sure warning system may not operate properly.
• If non-genuine Toyota wheels are used.• A tire has been replaced with a tire
that is not an OE (Original Equipment) tire.• A tire has been replaced with a tire
that is not of the specified size. • Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.• 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. • If the tire inflation pressure is extremely higher than the specified
level. • 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.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-play, airport or other facility that gen-
erates strong radio waves or electrical noise.• When carrying a portable radio, cellu-
lar phone, cordless phone or other wireless communication device.
●When the vehicle is parked, the time taken for the warning to start or go off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the not to able detect.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning
system will change in accordance with driving conditions. For this reason, the system may give a warning even if the
tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to
when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or

■Replacing tires and wheels
If the ID code of the tire pressure warn- ing valve and transmitter is not regis-tered, the tire pressure warning system
will not work properly. After driving for about 10 minutes, the tire pressure warning light blinks for 1 minute and
stays on to indicate a system malfunc- tion.
■The tire pressure warning sys-
tem must be init ialized in the
following circumstances:
When rotating front and rear tires
which have different tire inflation
pressures.
When changing the tire size.
When the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
When changing between two
registered wheel sets.
When the tire pressure warning
system is initialized, the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system

■Repairing or replacing tires,
wheels, tire pressure warning valves, transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as
the tire pressure warning valves and transmitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves, corrode the valve, and cause sticking and
air leaks.
●When replacing tire valve caps, do
not use tire valve caps other than those specified. The cap may become stuck.
■To avoid damage to the tire pres-sure warning valves and trans-mitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate
properly. If a liquid sealant is used, contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when
replacing the tire. ( P.366)

■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drivetrain
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Instructions for checking tire infla-tion 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 or 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.It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( P.454)

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

6-3. Do-it-yourself maintenance
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters 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, the tire pressure warning valves and transmitters must be
installed. ( P.366)
WARNING
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards, expansion joints, sharp edges on the road, etc.)

on. If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.

Maintenance and care
■When removing the wheel orna-
ment (vehicles with an emergency tire puncture repair kit)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( P.327)
Use only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
WARNING
■When replacing wheels
●Do not use wheels that are a differ- ent size from those recommended in the Owner’s Manual, as this may
result in a loss of handling control.
●Never use an inner tube in a leak-
ing wheel which is designed for a tubeless tire.Doing so may result in an accident,
causing death or serious injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing inward ( P.431). 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.
●Never use oil or grease on the wheel bolts or wheel nuts.Oil and grease may cause the
wheel nuts to be excessively tight- ened, 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.
■Use of defective wheels prohib-ited
Do not use cracked or deformed wheels. Doing so could cause the tire to leak air during driving, possibly
causing an accident.
NOTICE
■Replacing tire pressure warning valves and transmitters
●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 retailer or Toyota authorized repairer, or any reliable
repairer. In addition, make sure to purchase your tire pressure warn-ing valves and transmitters at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●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.
