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.

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.

●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.

■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 performing wheel posi-
tion registration
●Normally, wheel position registra-
tion can be completed within
approximately 30 minutes.
●Wheel position registration is per-
formed while driving at a vehicle
speed of approximately 25 mph
(40 km/h) or more.
■The initialization operation
●If the power switch is turned off
while registering the wheel posi-
tion, the next time the power
switch is turned to ON, the wheel
position registr ation will resume
and it will not be necessary to
restart the procedure.
●While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-information display, if
the inflation pres sure of a tire
drops, the tire pressure warning
light will come on.
■If the tire pressure warning sys-
tem is not registered properly
●In the following situations, wheel
position registration may take lon-
ger than usual to b e completed or
may not be possible.
• Vehicle is not driven at approxi-
mately 25 mph ( 40 km/h) or more
• Vehicle is driven on unpaved roads
If initialization does not complete
after driving for 1 hour or more, park
the vehicle in a safe place for
approximately 15 minutes and then
drive the vehicle again.
●If the vehicle is reversed during
wheel position registration, all
data collected until then will be
cleared. Perform driving again.
■When you need to setting
the tire pressure
In the following situations, it will
be necessary to perform the tire
inflation pressure setting proce-
dure of the tire pressure warning
system.
 When the specified tire infla-
tion pressure has changed,
such as due to carried load,
etc.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
If the tire inflation pressure has
been adjusted to the specified
level, perform the tire inflation
setting procedure by selecting
specified inflation pressure on
the multi-information display.
When the tire inflation pressure
is to be other than specified,
such as when tires other than
the specified size are used, etc.,
set the tire inflation pressure
using the current pressure.
Make sure to adjust the tire
inflation pressure of each tire to
the appropriate level before per-
forming tire pressure setting.
The tire pressure warning sys-
tem operates based on this tire
inflation pressure.
