●The vehicle hydroplanes while driv-
ing at high speed on wet or slick
roads.
■Stopping distance when the ABS
is operating may exceed that of normal conditions
The ABS is not designed to shorten
the vehicle’s stopping distance. Always maintain a safe distance from
the vehicle in front of you, especially
in the following situations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with pot-
holes or uneven surfaces
■TRC may not operate effectively
when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC
system is operating. Do not drive the vehicle in conditions where stability
and power may be lost.
■When the VSC and/or brake LSD
function is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a
speed appropriate to the road condi- tions. As these are the systems to
help ensure vehicle stability and driv-
ing force, do not turn the TRC/VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pattern
and total load capacity. In addition, make sure that the tires are inflated to
the recommended tire inflation pres-
sure level.
The ABS, TRC and VSC systems will
not function correctly if different tires
are installed on the vehicle. Contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem
or modifying the suspension will affect the driving assist systems, and may
cause a system to malfunction.

rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Preparation for winter
WA R N I N G
■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, and that are the same size, same
maker, same brand and tread pat-
tern.
●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 a ll, not just some
wheels.
■Driving with tire chains
●When any of the tires are punc-
tured, you can seal the tire tempo- rarily. However, do not use the tire
chain on a sealed tire. If any of the
rear tires are punctured although it is required to use tire chains, con-
tact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
●Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the
vehicle 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 30 km/h (19 mph),
whichever is lower.
• Avoid driving on bumpy road sur-
faces or over potholes.
• Avoid sudden acceleration, abrupt
steering, sudden braking and shift- ing operations that cause sudden
engine braking.
• Slow down sufficiently before enter- ing a curve to ensure that vehicle
control is maintained.

3026-3. Do-it-yourself maintenance
Replace the tires if the treadwear indi-
cators are showing 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 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 dealer or repairer, or another duly qualified and equipped pro-
fessional.
■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.
■Low profile tires
Generally, low profile tires will wear
more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains
on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
■If the tread on snow tires wears
down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
WA R N I N G
■When inspecting or replacing
tires
Observe the following precautions 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 accident result-
ing in death or serious injury.
●Make sure to insta ll 4 tires that are
of the specified size, and that all 4
tires are the same size, same maker, same brand and tread pat-
tern.
●Do not use tire sizes other than
those recommended by Toyota.
●Only use radial 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.
NOTICE
■Low profile tires
Low profile tires may cause greater
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 under-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.

3046-3. Do-it-yourself maintenance
pressure has been adjusted.
●Tire inflation pressure 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 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 specified
level.
• If tires not equipped with 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. • When driving near a TV tower, electric
power plant, gas station, radio station,
large display, airport or other facility
that generates strong radio waves or electrical noise
• When carrying a portable radio, cellu-
lar phone, cordless phone or other wireless communication device
If tire position information is not correctly
displayed due to the radio wave condi- tions, the display ma y 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.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. For this reason, the
system may give a warning even if the tire pressure does not reach a low
enough level, or if the pressure is higher
than the pressure that was adjusted to when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters 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.
Have tire pressu re warning valve
and transmitter ID codes regis-
tered by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
( P. 3 0 6 )
■Replacing tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis- tered, 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

Maintenance and care
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure
warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are
replaced, tire pressure warning valves and transmitters mu st be installed.
( P.304)
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.
Wheel selection
WA R N I N G
■When replacing wheels
●Do not use wheels that are a differ-
ent size from those recommended in the Owner’s Manual, as this may
result in a loss of handling control.
●Never use an inner tube in a leak-
ing wheel which is designed for a
tubeless tire. Doing so may result in
an accident, causing death or seri- ous injury.
■When installing the wheel nuts
Never use oil or grease on the wheel
bolts or wheel nuts. Oil and grease
may cause the wheel nuts to be excessively tightened, leading to bolt
or disc wheel damage. In addition, the
oil or grease can cause the wheel nuts to loosen and the wheel may fall
off, causing an accident and resulting
in death or serious injury. Remove any oil or grease from the wheel bolts
or wheel nuts.
■Use of defective wheels prohib-
ited
Do not use cracked or deformed wheels. Doing so could cause the tire
to leak air during driving, possibly
causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning
valves and transmitters, make sure
to have tires serviced by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer or other qualified service shop. In addition, make sure to pur-
chase your tire pressure warning
valves and transmitters at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
