Maintenance and care
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 by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
( P.443)
■Replacing tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis-
tered, the tire pre ssure 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.

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 and the
tire pressure warning valves could
be bound.
●When replacing tire valve caps, do
not use tire valve caps other than those specified. The cap may
become stuck.

4427-3. Do-it-yourself maintenance
■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 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.
Initialization cannot be performed while
the vehicle is moving.
2 Adjust the tire inflation pressure
to the specified co ld tire inflation
pressure level. ( P.533)
Make sure to adjust the tire pressure to
the specified cold tire inflation pressure level. The tire pressure warning system
will operate based on this pressure
level.
3 Turn the engine switch to ON.
4 Press and hold the tire pressure
warning reset switch until the
tire pressure warning light blinks
slowly 3 times.
5 Wait for a few minutes with the
engine switch in ON and then
turn the engine switch off.
■Initialization procedure
●Make sure to carry out initialization
after adjusting the tire inflation pres- sure.
Also, make sure the tires are cold
before carrying out initialization or tire inflation pressure adjustment.
NOTICE
■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.441)

Maintenance and care
●If you have accidentally turned the
engine switch off during initialization, it is not necessary to press the reset
switch again as initialization will
restart automatically when the engine switch is turned to ON the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires are cold, and conduct initialization
again.
■When initialization of the tire pres-
sure warning system has failed
Initialization can be completed in a few
minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to
record tire inflation pressure settings are unsuccessful, have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After driving for a certain period of
time since the initialization has been
completed, the wa rning light comes on after blinking for 1 minute.
The tire pressure warning valve
and transmitter is equipped with a
unique ID code. When replacing a
tire pressure warning valve and
transmitter, it is necessary to regis-
ter the ID code. Have the ID code
registered by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
■Registering ID codes
The ID codes of the tire pressure warn- ing valve and transmitters for two sets of
wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels
of both normal tires and snow tires are registered beforehand.
For information about changing ID
codes, ask any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
WA R N I N G
■When initializing the tire pres-
sure warning system
Do not operate the tire pressure warn- ing reset switch without first adjusting
the tire inflation pressure to the speci-
fied level. Otherwise, the tire pressure warning light may not come on even if
the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.
Registering ID codes

4447-3. Do-it-yourself maintenance
Tire inflation pressure is specified
on the label on the driver’s side pil-
lar as shown.
Left-hand drive vehicles
Right-hand drive vehicles
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres-
sure may 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 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.533)

Maintenance and care
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.441)
WA R N I N G
●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
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back
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.

■When removing the wheel orna-
ment (vehicles with a wheel cap clip)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( P.397)
Use only Toyota wheel nuts and
wheel nut wrenches designed for
WA R N I N G
■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
●Vehicles with a steel wheel: Be sure
to install the wheel nuts with the
tapered ends facing inward. ( P.504) Installing the nuts with the
tapered ends facing outward can
cause the wheel to break and even- tually cause the wheel to come off
while driving, which could lead to an
accident resulting in death or seri- ous 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
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer or other qualified service
shop. In addition, make sure to pur- chase your tire pressure warning
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.
