Maintenance and care ■
When to replace your vehicle’s tires
Tires should be replaced if: ●
The treadwear indicators are showing on a tire.●
You have tire damage such as c uts, splits, cracks deep enough t o
expose the fabric or bulges indicating internal damage●
A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consul t with your Toyota dealer.■
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitt er is not
registered, the tire pressure w arning system will not work prop erly. After
driving for about 20 minutes, t he tire pressure warning light c omes on
after blinking for 1 minute to indicate a system malfunction.■
Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if they have seldom or never b een used or damage is not obvious .
■
If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■
Low profile tires
Generally, low profile tires will wear more rapidly and tire gr ip perfor-
mance will be reduced on snowy and /or icy roads wh en compared t o
standard tires. Be sure to use snow tires or tire chains on sno wy and/or
icy roads and drive carefully at a speed appropriate for road a nd weather
conditions.

■
Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axl e or the
rear axle, whichever is greater.
■
Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to hi ghway
driving under dry conditions. Since summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-cover ed
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 provide better traction in sno w and to
be adequate for driving in most winter conditions, as well as f or use
year round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so,
all season tires fall short in acceleration and handling perfor mance
compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as th e originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tir es without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. (  P. 261)For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. (  P. 4 7 4 )

Maintenance and care WARNING■
Tire pressure warning system operation
The tire pressure warning system may not provide warning immedi ately
if a tire bursts or if sudden air leakage occurs.■
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 handling characteristics, which may lead to an accide nt
resulting in death or serious injury. ●
Make sure to install 4 tires that are of the specified size, an d that all 4
tires are the same size, same ma ker, same brand and tread patte rn.●
Do not use tire sizes other t han those recommended by Toyota.●
Only use radial tires.●
Do not mix summer, all season and snow tires.
●
Do not use tires that have be en used on anot her vehicle.
Do not use tires if you do not kno w how they were used previous ly.
NOTICE■
Repairing or replacing tires, wheels, tire pressure warning val ves,
transmitters and tire valve caps
●
When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not hand led
correctly.
●
Make sure to install the tire valve caps. If the tire valve cap s are not
installed, water could enter the tire pressure warning valves a nd the
tire pressure warning valves could be bound.
●
When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The c ap may become stuck.

NOTICE■
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, r educing
the cushioning ability of the tire s. In addition, driving on ro ugh roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.■
Low profile tires and wheels
Low profile tires may cause greater damage than usual to the ti re wheel
when receiving impact from the road surface. Therefore pay attention to
the following: ●
Be sure to use proper tire inflation pressure. If tires are und er-inflated,
they may be damaged more severely.●
Avoid pot holes, uneven pavement, curbs and other road hazards.
Failure to do so may lead to severe tire and wheel damage.
■
If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be rui ned.

Maintenance and care ■
Effects of inco rrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in th e 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 frequ ent refilling, have it checked by your Toy ota dealer.■
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following: ●
Check only when the tires are cold.
If your vehicle has been parked fo r at least 3 hours and has no t been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●
Always use a tire pressure gauge.
It is difficult to judge if a tir e is properly inflated based o nly on its
appearance.
●
It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pre ssure after
driving.
●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehi cle
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 condition s may occur
which could lead to an accident resulting in death or serious injury:●
Excessive wear●
Uneven wear●
Poor handling●
Possibility of blowouts result ing from overheated tires●
Air leaking from bet ween tire and wheel●
Wheel deformation and/or tire damage●
Greater possibility of tire damage while driving ( due to road h azards,
expansion joints, sharp edges in the road, etc.)
NOTICE■
When inspecting and adjust ing tire inflation pressure
Be sure to reinstall the tire valve caps.
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 pressu re.

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.
■ Wheel selection
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 avail able at your Toyota dealer.
* : Conventionally refer red to as “offset”.
Toyota does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
● Use only Toyota wheel nuts and wrenches designed for use
with your aluminum wheels.
● When rotating, repairing or chang ing your tires, check that the
wheel nuts are still tight afte r driving 1000 m iles (1600 km).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine balan ce weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care NOTICE■
Replacing tire inflation pressu re warning valves and transmitte rs●
Because tire repair or replaceme nt may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced b y your
Toyota dealer or other qualifie d service shop. In addition, mak e sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.●
Ensure that only genuine Toyota w heels are used on your vehicle .
Tire pressure warning valves and transmitters may not work prop erly
with non-genuine wheels.
