4426-3. Do-it-yourself maintenance
■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 cuts, splits, cracks deep enough t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID codes of the tire pressure warning valve and transmit ters are not
registered, the tire pressure warning system will not work properly. In this
case, after driving for about 20 minutes, the tire pressure warning light will
blink for approximately 1 minute and then illuminate to indicat e a system
malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (vehicles with 18 or 19-inch wheels)
Generally, low profile tires will wear more rapidly and tire gr ip perfor-
mance will be reduced on snowy and /or icy roads when compared to
standard tires. Be sure to use snow tires on snowy and/or icy r oads and
drive carefully at a speed approp riate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of t he 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.
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. 5 3 5 )

■Situations in which the tire pressure warning system may not oper-
ate properly
●In the following situations, the tire pressure warning system m ay not
operate properly.
• If non-genuine Toyota wheels are used.
• If a tire has been replaced with a tire that is not an OE (Ori ginal
Equipment) tire.
• If a tire has been replaced with a tire that is not of the spe cified size.
• If tire chains, e tc. are installed.
• If a window tint that affects r adio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is much higher than the specifi ed level.
• If wheels not equipped with tire pressure warning valve and tr ansmit-
ter are used.
• If the ID codes of the tire pre ssure warning valve and transmi tters are
not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• When driving near a TV tower, electric power plant, gas statio n, radio
station, large display, airport or other facilit y that generates strong
radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
If tire position information is not correctly displayed due to the radio
wave conditions, the display ma y be corrected by changing the l ocation
of the vehicle as the radio wa ve conditions may change.
●When the vehicle is stopped, the time taken for the warning to start or
turn off may be longer.
●When the inflation pressure of a tire drops rapidly, for exampl e when a
tire has burst, the warning may not operate.
■Initialization procedure
●Make sure to perform the initialization procedure after adjusti ng the tire
inflation pressure.
Also, make sure the tires are cold before performing the initia lization
procedure or adjusting the tire inflation pressure.
●If the power switch is turned off during initialization, it is not necessary to
restart the initialization procedure from the beginning as it w ill begin
automatically when the power swit ch is turned back to ON mode.
●If initialization has accidentally been started when it is not necessary,
adjust the tire inflation pressu re to the specified level when the tires are
cold and then perform the ini tialization procedure again.
●While the position of each tire is being determined and the inf lation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning l ight will come
on.

WARNING
■When inspecting or replacing tires
Observe the following precaut ions 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 o r serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted o r bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not kn ow how they were used previously.
■When initializing the tire pressure warning system
Do not initialize the tire press ure warning system without firs t adjusting
the tire inflation pressure to t he specified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation p ressure is
low, or it may come on when the tire inflation pressure is actu ally nor-
mal.

NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valve
and transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitters, contact your Toyota dealer as the tire pressure
warning valve and transmitters may be damaged if not handled co r-
rectly.
●Make sure to install the tire val ve caps. If the tire valve caps are not
installed, water may enter the valves of the tire pressure warn ing valve
and transmitters and the valves may become stuck.
●When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valve and transmit -
ters
When a tire is repaired with liqui d sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 439)
■Driving on rough roads
Take particular care when drivi ng on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the t ires. In addition, driving on ro ugh roads
may cause damage to the tires themselves, as well as the vehicl e’s
wheels and body.
■Low profile tires (vehicles w ith 18 or 19-inch wheels)
Low profile tires may cause gre ater damage than usual to the tire wheel
when sustaining 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 potholes, uneven pavement, curbs and other road hazards. Fail-
ure to do so may lead to severe tire and wheel damage.
■If tire inflation pressure of each tire becomes low while drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.

Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to defla te.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation p ressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t 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 drivetrain
If a tire needs frequent inflating , have it checked by your Toyota dealer.

Maintenance and care
■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 for at least 3 hours or has not 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 tire is properly inflated based o nly on its appear-
ance.
●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 in flated, the following conditions may occur
which could lead to an accident resulting in death or serious i njury:
●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 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 adjusti ng 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 pressu re.

When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that hav e been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing valve
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressu re. When-
ever wheels are replaced, tire pressure warning valve and trans mitters
must be installed. ( P. 439)
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.
