ing for 1 hour or more, park the vehicle
in a safe place for approximately 20
minutes and then drive the vehicle
again.
■When initializing
●Initialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
●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.
●The tire pressure warning system can
be initialized by yourself, but depend-
ing on the driving conditions and driv-
ing environment, initialization may
take some time to complete.
■The initialization operation
●If you have accidentally turned the
power switch to OFF during initializa-
tion, it is not necessary to restart the
initialization again as initialization will
restart automatically when the power
switch has been turned to ON for the
next time.
●If you accidentally perform initializa-
tion when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization
again.
●While the position of each tire is being
determined and the inflation pres-
sures are not being displayed on the
multi-information display, if the infla-
tion pressure of a tire drops, the tire
pressure warning light will come on.
■If the tire pressure warning system
is not initialized properly
●In the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Nor-
mally, initialization completes within
approximately 30 minutes.
• Vehicle is not driven at approximately
40 km/h (25 mph) or more• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit-
ters of your vehicle over those of other
vehicles.
• 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 initialization does not complete after
driving for 1 hour or more, park the
vehicle in a safe place for approxi-
mately 20 minutes and then drive the
vehicle again.
●If the vehicle is reversed during initial-
ization, the data up to that point is
reset, so perform the initialization pro-
cedure again from the beginning.
●In the following situations, initialization
will not be started or was not com-
pleted properly and the system will not
operate properly. Perform the initial-
ization procedure again.
• If, when attempting to start initializa-
tion, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven
for about 20 minutes after performing
initialization, the tire pressure warning
light blinks for approximately 1 minute
and then illuminates.
If initialization cannot be completed after
performing the above procedure, con-
tact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.

■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 the
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.590)
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 in 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
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 must be installed.
( P.488, 500)
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
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 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.
5007-3. Do-it-yourself maintenance
Use only Toyota wheel nuts and
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 bal-
ance weights or equivalent and a
plastic or rubber hammer when
balancing your wheels.
