Wheels
nWhen replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves an
d transmitters that allow the tire pressure warning system to
provide advanced 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. 2 5 9 )
If a wheel is bent, cracked or heavily corroded, it should be
replaced.

Otherwise, the tire may separate from the wheel or cause loss of
ha
ndling control.
nWheel selection
When replacing wheels, care shou ld
be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:
l Whee
ls of different sizes or types
lUs
ed wheels
lBe
nt wheels that have been straightened
n Aluminum wheel precau
tions (if equipped)
l Use only
Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
l When
rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Be
careful not to damage the aluminum wheels when using
tire chains.
l Use only T
oyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re
sult in loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
NOTICE
nReplacing tire pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warn-
ing valves and transmitte rs, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
lEnsure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

CAUTION
nIf the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and re sult in death or serious injury.
lStop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
lIf the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a fl at tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.
nMaintenance of the tire
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle pl acard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)

5-2. Steps to take in an emergency
CAUTION
As an added safety feature, your v
ehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire main tenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low ti re pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction tellt ale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
