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
any reliable repairer. ( P.484)
■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.

■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.
Your vehicle is equipped with tire
pressure warning system with the
function to have ID codes regis-
tered for a second wheel set, for
example a winter set, by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
After registration of a second wheel
set, either of these two wheel sets
can be selected for usage with the
tire pressure warning system.
■Operating conditions for the
function

change of wheel set only if a sec-
ond wheel set has been regis-
tered. If no second wheel set has
been registered, no change will
be made when selecting this
function in the menu.
 Only a change between both
registered wheel set is possible,
mixing between these wheel sets
is not supported.
■How to change between wheel
sets

■When initializing the tire pres-
sure warning system
Do not initialize the tire pressure warning system withou t 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.

■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.
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. 5 7 3 )

■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.
WA R N I N G
■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
●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.

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 (vehicles
with a tire pressure warning sys- tem)
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.482)
■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.440)
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 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.547) Installing the nuts with the tapered ends facing out-
ward 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.

4887-3. Do-it-yourself maintenance
Use only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
 When rotating, repairing or
changing your tires, check that
the wheel nuts ar e still tight after
driving 1600 km (1000 miles).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine balance
weights or equivalent and a plas-
tic or rubber hammer when bal-
ancing your wheels.
WA R N I N G
●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 (vehicles
with a tire pressure warning sys-
tem)
●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. 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.
