5 Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Registration is complete when the tire
pressure warning light turns off and the inflation pressure of each tire is dis-played on the multi-information display.
Registration may take longer than approximately 1 hour in certain situa-tions, such as when the vehicle is
stopped for a long time at traffic lights, etc. ( P.340)
After registering the ID codes, make
sure to initialize the tire pressure warn- ing system. ( P.337)
■When registering ID codes
●Before performing ID code registra- tion, make sure that no wheels with tire pressure warning valve and trans-
mitters installed are near the vehicle.
●Make sure to initialize the tire pres-
sure warning system after registering the ID codes. If the system is initial-ized before registering the ID codes,
the initialized values will be invalid.
●As the tires will be warm when regis-
tration is completed, make sure to allow the tires to cool before perform-ing initialization.
■Canceling ID code registration
●To cancel ID code registration after it has been started, operate the multi-
information display to select “Identify-
ing Each Wheel & Position”. ( P.339)
●If ID code registration has been can-
celed, the tire pressure warning light will blink for approximately 1 minute when the power switch is turned to
ON mode and then illuminate. The tire pressure warning system will be oper-ational when the tire pressure warning
light turns off.
●If the warning light does not turn off
even after several minutes have elapsed, ID code registration may not have been canceled correctly. To can-
cel registration, perform the ID code registration start procedure again and then turn the power switch off before
driving.
■If ID codes are not registered prop- erly
●In the following situations, ID code registration may take longer than usual to be completed or may not be
possible. (Usually, the vehicle will need to be driven for approximately 10 to 30 minutes to complete ID code
registration.) If ID code registration is not complete after driving for approximately 30 min-
utes, continue driving for a while. • If the vehicle is driven on an unpaved road, it may take longer than normal
to complete registration. • If the vehicle is backed up while per-forming registration, data collected
during registration will be cleared, and it will take longer than normal to com-plete.
• If the vehicle is driven in heavy traffic or another situation where other vehi-cles are driven close by, it may take
time for the system to recognize the tire pressure warning valve and trans-mitters of your vehicle over those of
other vehicles. • If a wheel with a tire pressure warning valve and transmitter installed is
inside or near the vehicle, registration of the ID codes for the installed wheels may not be possible.
If ID registration is not complete after

driving for approximately 1 hour, park
the vehicle in a safe place for approxi-
mately 20 minutes and then perform the
ID code registration procedure again.
●In the following situations, ID code registration will not be started or was not completed properly and the sys-
tem will not operate properly. Perform the ID code registration procedure again.
• If, when attempting to start ID code registration, the tire pressure warning light does not blink slowly 3 times.
• If, when the vehicle has been driven for about 10 minutes after performing ID code registration, the tire pressure
warning light blinks for approximately 1 minute and then illuminates.
●If ID code registration cannot be com-pleted after performing the above pro-cedure, contact 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 autho-
rized 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

Maintenance and care
■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.
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
●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.

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.336)
■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.298)
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.

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.402). 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.

Maintenance and care
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 are 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.
WARNING
●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.
