The motor compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the motor
compartment
●Make sure that “POWER ON”
on the multi-information display
and the “READY” indicator are
both off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the
motor, power control unit, radia-
tor, etc., right after driving as
they may be hot. Coolant and
other fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the motor compartment.
●Do not smoke, cause sparks or
expose an open flame to the 12-
volt battery. 12-volt battery
fumes are flammable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.

Check if the treadwear indica-
tors are showing on the tires.
Also check the tires for uneven
wear, such as excessive wear
on one side of the tread.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators
is shown by a “TWI” or “ ” mark,
etc., molded into the sidewall of
each tire. Replace the tires if the treadwear
indicators are s
howing on a tire.
■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
to expose the fabric, and bulges
indicating internal damage.
●A tire goes flat repeatedly or can-
not 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.
■Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage is not obvious.
■Maximum load of tire
Check that the n umber given by
dividing the maximum load by 1.10
of the replacement 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.
For the GAWR, see the Certification
Regulation Label. For the maximum
load of the tire, see the load limit at
maximum cold tire in flation pressure
mentioned on the sidewall of the
tire. ( P.556)
■Tire types

Maintenance and care
Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performanc e as snow tires,
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 install-
ing snow tires, be sure to replace all
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions a s well as for use
year-round. All season tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
●Snow 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
originally installed tires. Since your
vehicle has radial tires as original
equipment, make sure your snow
tires also have radial construction.
Do not install stud ded tires without
first checking local regulations for
possible restrictions. Snow tires
should be installed on all wheels.
(  P.393)
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.
WARNING
■When inspecting or replacing
tires
Observe the following precautions
to prevent accidents.
Failure to do so may cause dam-
age to parts of the drive train as
well as dangerous handling char-
acteristics, which may lead to an
accident resulting in death or seri-
ous injury.
●Do not mix tires of different
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than
those recommended by Toyota.
●Do not mix differently con-
structed tires (radial, bias-belted
or 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
know how they were used previ-
ously.
NOTICE
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
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.

4747-3. Do-it-yourself maintenance
Owners Manual_USA_M42C01_en
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
Front
■When rotating the tires
Make sure that the power switch is
OFF. If the tires are rotated while the
power switch is in ON, the tire posi-
tion information will not be updated.
If this accidentally occurs, either turn
the power switch to OFF and then to
ON, or initialize the system after
checking that the tire pressure is
properly adjusted.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
The tire pressure warning sys-
tem of this vehicle adopts a 2-
type warning system.
 When “Adjust Pressure” is
displayed (Normal Warning)
A warning with the tire pressure
warning light and warning buzzer
when there is an unknown level of
low tire pressure with the appear-
ance of the tire due to natural air
leakage as well as the pressure
lowering due to changes in the
pressure according to the outside
temperature.
When “Immediately Check
Tire when Safe” is displayed
(Emergency Warning)
A warning with the tire pressure
warning light and warning buzzer
when there is a k nown level of low
tire pressure with the appearance
of the tire due to pressure suddenly
lowering.
However, the system may not be
able to detect sudden tire ruptures
(bursting, etc.).
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
NOTICE
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks . Make sure to
check tire inflation pressure as part
of your routine o f daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after infl ation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature.
The displayed values may also be
different from the values mea-
sured using a tire pressure gauge.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a
tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a
tire that is not of the specified size.
• Tire chains etc. are equipped.
• If a window tint that affects the radio 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 extremely higher than the speci-
fied level.
• If wheels without tire pressure warning valves and transmitters
are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.

4767-3. Do-it-yourself maintenance
Owners Manual_USA_M42C01_en
●Performance may be affected in
the following situations.
• Near a TV tower, electric power
plant, gas station, radio station,
large display, airpo rt or other facil-
ity 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 cor-
rectly displayed due to the radio
wave conditions, the display may be
corrected by driving and changing
the radio wave conditions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
(  P.481)
■When replacing the tires and
wheels
If the ID code of the tire pressure
warning valve and transmitter is not
registered, the tire pressure warning
system will not work properly. After driving for about 10 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.

mitters
NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your
Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves and the tire pressure
warning valves could be bound.
●When replacing tire valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.
■To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repa ired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer as soon as possible. After
use of liquid sealant, make sure to
replace the tire p ressure warning
valve and transmitter when repair-
ing or replacing the tire.
