stays on to indicate a system malfunc-
tion.
■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
 When rotating the tires.
 When the tire inflation pressure
is changed such as when chang-
ing traveling speed.
 When changing the tire size.
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.
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

■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.
■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 or other qualified ser-
vice shop as soon as possible. After use of liquid sealant, make sure to
replace the tire pressure warning
valve and transmitter when repairing or replacing the tire. ( P.304)
Initializing the tire pressure
warning system

tire pressure warning light blinks
slowly 3 times.
5 Wait for a few minutes with the
engine switch ON and then turn
the engine switch off.
■If you press the tire pressure warn-
ing reset switch accidentally
If initialization is performed, adjust the
tire inflation pressure to the specified
level and initialize the tire pressure warning system again.
■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.
●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 has been turned to ON for 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 syst em 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, tire pressure warning light does not blink 3 times.
●After carrying out the initialization pro-cedure, the tire pressure warning light
blinks for 1 minute then stays on after
driving for 10 minutes.
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

■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

Maintenance and care
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.
In addition to the set of tire pressure
warning system sensor ID codes initially registered to the vehicle, a second set of
ID codes can be registered.
A second set of tire pressure warning system sensor ID codes can be regis-
tered at your Toyota dealer or repairer,
or another duly qualified and equipped professional. When 2 sets of ID codes
have been registered, either ID code set
can be selected.
1 Park the vehicle in a safe place
and turn the engine switch to
ON.
2 Press the tire pressure warning
reset switch 3 times within 3
seconds.
3 The tire pressure warning light
will illuminate for 3 seconds and
then blink 3 times.
4 The tire pressure warning light
will blink for 1 minute and then
illuminate.
5 When the ID code change has
completed, the tire pressure
warning light will turn off.
Check that tire pressures are displayed
on the multi-information display.

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, tire pressure warning valves and transmitters mu st be installed.
( P.304)
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.
Wheel selection
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 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.
■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.
