■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
1 Park the vehicle in a safe place
and turn the engine switch off,
wait for approximately 15 min-
NOTICE
■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)

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.)
NOTICE

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.

restricted. When the light comes on red, the assist to the power steering is lost and handling operations 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 pre- cautions.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 inflation pressure immediately.
●Vehicles with a compact spare tire and full-size spare tire: 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 retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture repair kit: 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, repair the flat tire by using emergency tire puncture repair kit.
●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 leak-age should occur
The tire pressure warning system
may not activate immediately.

The expiry date is marked on the bot- tle. The sealant should be replaced before the expiry date. Contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a sin- gle tire. If the sealant has been used and needs to be replaced, purchase a
new bottle at any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer. The compres-
sor is reusable.
●The sealant can be used when the
outside temperature is from -30°C (- 22°F) to 60°C (140°F).
●The kit is exclusively designed for size and type of tires originally installed on your vehicle. Do not use it for tires that
a different size than the original ones, or for any other purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be removable if it is not
cleaned at once. Immediately wipe away the sealant with a wet cloth.
●During operation of the repair kit, a loud operation noise is produced. This does not indicate a malfunction.
