■Tire types
●Summer tires
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 radi
al construction.
Do not install studded tires without
first checking local regulations for
possible restrictions. Snow tires
should be installed on all wheels.
( P.253)
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.
■Checking the tire valves
When replacing the tires, check the
tire valves for deformation, cracks,
and other damage.
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.

Maintenance and care
Rotate the tires in the order
shown.Front
To equalize tire w
ear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Vehicles with a tire pressure warn-
ing system: Do not fa il to initialize
the tire pressure warning system
after tire rotation.
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

NOTICE
■Low profile tires (18-inch
tires)
Low profile tires may cause
greater damage th an usual to the
tire wheel when sustaining impact
from the road surface. Therefore,
pay attention to the following:
●Be sure to use pro per tire infla-
tion pressure. If tires are
under-inflated, they may be
damaged more severely.
●Avoid potholes, uneven pave-
ment, curbs and other road haz-
ards. Failure to do so may lead
to severe tire and wheel dam-
age.
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
These conditions may cause
losses in tire inf lation pressure,
reducing the cushio ning ability of
the tires. In addit ion, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.

■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 of daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the engine switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after inflation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature.
The displayed values may also be
different from th e 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.
• An auxiliary-supported run-flat tire is 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 tires not equipped with tire pres- sure warning valves and transmit-
ters 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.
●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.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system w ill change in
accordance with driving conditions.
For this reason, the system may
give a warning even if the tire pres-
sure does not reach a low enough
level, or if the p ressure is higher
than the pressure that was adjusted
to when the system w as initialized.

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
warning computer and the tire
pressure warning system must
be initialized. Have tire pressure
warning valves and transmitter
ID codes registered by your Toy-
ota dealer. (P.322)
■Replacing 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 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.
It is necessary to register the
position of each wheel after per-
forming a tire rotation.
Wheel position registration can
be performed by oneself. Wheel
position registration is per-
formed by driving forward with
moderate left and right turns.
However, depending on the driv-
ing conditions and driving envi-
ronment, registration may take
some time to complete.

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 pr essure 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 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.315)
