Maintenance and care
nEffects of incorrect tire inflation pressure
Driving with incorrect ti
re inflation pressure may result in the following:
lReduced fuel efficiency
lReduced driving comfort and tire life
lReduced safety
lDamage to the drive train
If a tire needs frequent re
filling, have it checked by your Toyota dealer.
nInstructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
lCheck only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or
1.5 km, you will get an accurate cold
tire inflation pressure reading.
lAlways use a tire pressure gauge.
The appearance of the tire can be mi
sleading. In addition, tire infla−
tion pressures that are even just a few pounds off can degrade ride
and handling.
lDo not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

404 4−3. Do−it−yourself maintenance
CAUTION
n Proper inflation is critical to save tire performance
Keep your tires properly inflated. Otherwise, the following conditions
may occur and result in an accident causing death or serious injury.
lExcessive wear
lUneven wear
lPoor handling
lPossibility of blowouts resulting from overheated tires
lPoor sealing of the tire bead
lWheel deformation and/or tire separation
lA greater possibility of tire damage from road hazards
NOTICE
n When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
Without the valve caps, dirt or mo
isture could get into the valve and
cause air leakage, which could result in an accident. If the caps have
been lost, replace them as soon as possible.

Maintenance and care
Wheels
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
handling control.
nWheel selection
When replacing wheels, care should 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:
lWheels of different sizes or types
lUsed wheels
l
Bent wheels that have been straightened
n
Aluminum wheel precautions
l
Use only Toyota wheel nuts and wrenches 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).
lBe careful not to damage the aluminum wheels when using
tire chains.
lUse only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

406 4−3. Do−it−yourself maintenance
nWhen replacing wheels
The wheels of your Toyota are equipped with tire pressure warning valves
and 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. 392)
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in the
Owner ’s Manual, as this may result in loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a tube−
less tire. Doing so may result in an accident, causing death or serious
injury.
NOTICE
nReplacing tire pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warning
valves and transmitters, 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.
l
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.

nIf the tire pressure warning system is inoperative
The tire pressure warning system
will become inoperati ve in the follow−
ing conditions:
(When the condition becomes normal, the system will work properly.)
lIf tires not equipped with tire pressure warning valves and transmit−
ters are used.
lIf the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
lIf the tire inflation pressure is more than 73 psi (500 kPa, 5.1 kgf/cm2
or bar).
The tire pressure warning system may become inoperative in the follow−
ing conditions:
(When the condition becomes normal, the system will work properly.)
lIf electronic devices or facilities us ing similar radio wave frequencies
are nearby.
lIf a radio set at similar frequencies is in use in the vehicle.
lIf a window tint that affects the radio wave signals is installed.
lIf there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
lIf non−genuine Toyota wheels are used. (Even if you use Toyota
wheels, the tire pressu re warning system may not work properly with
some types of tires.)
lIf tire chains are used.
lIf the spare tire is in a location subject to poor radio wave signal
reception.
lIf a large metallic object which caninterfere with sign al reception is
put in the luggage compartment.
nIf the tire pressure warning light comes on after blinking for 1
minute frequently
If the tire pressure warning light comes on after blinking 1 minute fre−
quently when the “ENGINE START STOP” switch is turned to IGNITION
ON mode, have it checked by Toyota dealer.

CAUTION
n If 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 result 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 probable that you have a flat 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.
n If a blowout or sudden air loss should occur
The tire pressure warning system may not activate immediately.

458 5−2. Steps to take in an emergency
CAUTION
n Maintenance of the tires
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
placard 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.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS−ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under−inflated. Accordingly,
when the low tire pressu
re telltale (tire pressure 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).

When trouble arises
459 5−2. Steps to take in an emergency
CAUTION
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 te
lltale 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.
NOTICE
n Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres−
sure warning system may
not operate properly.
