nMaximum load of tire
Check that the maximum load of the re
placed tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Ratings (GAWR)
, see the Certification Label. ( P.
401, 507).
nTire types
1 Summer tires
Summer tires are high−speed performance tires best suited to highway
driving under dry conditions. Sinc
e summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow−covered or icy roads. For driving on snow−covered
roads or icy roads, the use of
snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to prov ide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires
For driving on snow−covered roads or icy roads, we recommend using
snow tires. If you need snow tires,
select tires of the same size, con−
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. (

Maintenance and care
nInitializing the tire pressure warning system
Initialize the tires with the tire inflat
ion pressure adjusted to the specified
level.
nIf you press the tire pressure reset switch accidentally
If initialization is performed, adjust t
he tire inflation pressure to the speci−
fied level and initialize the tire pressure warning system again.
nWhen the initialization of the tire pressure warning system has
failed
Initialization can be comp leted in a few minutes. However, in the follow−
ing cases, the settings have not b
een recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
lWhen operating the tire pressure warning reset switch, the warning
light does not flash 3 times and t
he setting message does not appear
on the multi−information display.
lAfter carrying out the initialization procedure, the tire pressure warn−
ing light blinks for 1 minute then stays on after driving for about 20
minutes.
nRoutine tire inflation pressure checks
The tire pressure warning system doe
s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.

Maintenance and care
CAUTION
n Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately
if a tire bursts or if
sudden air leakage occurs.
n When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han−
dling characteristics, which may le
ad to fatal or injury accidents.
lDo not mix tires of different makes, models, tread patterns or tread−
wear.
lDo not use tire sizes other than those recommended by Toyota.
lDo not mix radial, bias−belted, or bias−ply tires.
lDo not mix summer, all season and winter tires.
lDo not use tire that have been used on another vehicle.
Do not use tires if you do not know they were used previously.
n When initializing the tire pressure warning system
Do not press the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the spec
ified level. Otherwise, the tire pres−
sure warning light may not come on ev en if the tire inflation pressure is
low, or it may come on when the tire
inflation pressure is actually normal.
NOTICE
n Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
n To avoid damaging the tire pressure warning valves and transmit
ters
Do not use liquid sealants on flat tires.

NOTICE
n Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot−
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In
addition driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
n If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

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.
