WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit
specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
235/55R19 tires)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehi - cle being unable to be driven safely,
and may cause death or serious
injury.
●Do not drive in excess of the speed
limit specified for the tire chains being used, or 50 km/h (30 mph),
whichever is lower.
●Avoid driving on bumpy road sur -
faces or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shift-
ing operations that cause sudden engine braking.
●Slow down sufficiently before enter - ing a curve to ensure that vehicle
control is maintained.
●Do not use LTA (Lane Tracing
Assist) system (if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

Driving
Vehicles with 225/60R18 tires
Use the correct tire chain size when
mounting the tire chains. Chain size
is regulated for each tire size.
Side chain:
3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
30 mm (1.18 in.) in length
Cross chain:
4 mm (0.16 in.) in diameter
14 mm (0.55 in.) in width
25 mm (0.98 in.) in length
Vehicles with 235/55R19 tires
Tire chains cannot be mounted.
Snow tires should be used instead.
Regulations regarding the use of
tire chains vary depending on loca -
tion and type of road. Always check
local regulations before installing
chains.
■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
●Install tire chains on the front tires only. Do not install t ire chains on the
rear tires.
●Install tire chains on front tires as
tightly as possible. Retighten chains
after driving 0.5 - 1.0 km (1/4 - 1/2 mile).
●Install tire chains following the instruc - tions provided with the tire chains.
■Consumption of fuel and electricity
In cold temperatures, resistance of the
parts of a vehicle (tr ansmission, tires, etc.) generally incr eases, resulting in
increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of
this vehicle is als o likely to become worse in cold temperatures.

■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 inter -
nal 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, consult with any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Tire life
Any tire over 6 y ears old must be checked by a qualified technician even if
it has seldom or never been used or
damage is not obvious.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of t he tires as snow
tires is lost.
Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Toyota re commends that tire
rotation is carried out approximately
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents. Failure to do so may cause damage
to parts of the driv e train as well as
dangerous handling c haracteristics, which may lead to an accident result -
ing in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed 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 previously.
●Vehicles with compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
●Vehicles with emergency tire punc -
ture repair kit: Do not tow anything
if a tire that has been repaired using the emergency tire puncture repair
kit is installed. The load on the tire
may cause unexpec ted damage to the tire.
NOTICE
■Driving on rough roads
Take particular care when driving on
roads with loose sur faces or potholes. These conditions may cause losses in
tire inflation pressure, reducing the
cushioning ability of the tires. In addi - tion, driving on rough roads may
cause damage to the tires them -
selves, as well as the vehicle’s wheels and body.
■If tire inflation pressure of each tire becomes low while driving
Do not continue drivi ng, or your tires
and/or wheels may be ruined.

every 5000 km (3000 miles).
Do not fail to initial ize the tire pressure
warning system after tire rotation.
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 position informa -
tion 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 equi pped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla -
tion pressure before serious prob -
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system
 When “Adjust Pressure” is dis-
played (Normal Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low due to
natural air leakage or outside tempera-
ture. (Ways of coping: →P.575, 624)
When “Immediately Check tire
when Safe” is displayed (Emer -
gency Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low sud -
denly due to a blowout. (Ways of cop -
ing: →P.575, 582, 593)
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa -
tion display.
The unit can be changed.
■How to change the unit
1 Park the vehicle in a safe place
and turn the power switch off.
Changing the unit cannot be performed while the vehicle is moving.
2 Turn the power switch to ON.

■Routine tire inflation pressure checks
The tire pressure w arning 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 display
the tire inflation pressure after the
power switch is turned to ON. It may also take a few minutes to display the
tire inflation pressu re after inflation
pressure has been adjusted.
●Tire inflation pre ssure changes with
temperature. The displayed values may also be different from the values
measured using a tire pressure
gauge.
■Situations in which the tire pres - sure warning system may not oper -
ate properly
●In the following cases, the tire pres -
sure warning system may not operate
properly. • If non-genuine Toyota wheels are
used.
• A tire has been r eplaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been r eplaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supporte d run-flat tire is equipped.
• If a window tint tha t 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 t han the specified
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 dis -
play, airport or ot her facility that gen- erates strong radio waves or electrical
noise
• When carrying a port able radio, cellu-
lar 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 cor -
rected by driving and changing the
radio wave conditions.
