■The ABS does not operate effec-
tively when
●The limits of tire gripping perfor- mance have been exceeded (such
as excessively worn tires on a snow
covered road).
●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.

request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con- ditioning system after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P. 8 8 )
If you notice any of these clues, take
your vehicle to any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment or repair.

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.

Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and extend tire
life, Toyota recommends that tire rota-
tion is carried out at the same interval
as tire inspection.
Your vehicle is equipped 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 detected by the
tire pressure warning system can
be displayed on the multi-infor-
mation display.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and
a warning light. ( P.342)
■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 display
the tire inflation pressure after the
engine switch is turned to ON. It may also take a few minutes to display the
tire inflation pressure after inflation
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.
■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 addi-
tion, driving on rough roads may
cause damage to the tires them- selves, as well as the vehicle’s
wheels and body.

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

■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
 When rotating the tires.
 When the tire inflation pressure
is changed such as when chang-
ing traveling speed.
 When changing the tire size.
When the tire pressure warning
system is initialized, the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system
1 Park the vehicle in a safe place
and turn the engine switch off.
Initialization cannot be performed while
the vehicle is moving.
2 Adjust the tire inflation pressure
to the specified co ld tire inflation
pressure level.
Make sure to adjust the tire pressure to
the specified cold tire inflation pressure level. The tire pressure warning system
will operate based on this pressure
level.
3 Turn the engine switch to ON.

■Repairing or replacing tires,
wheels, tire pressure warning
valves, transmitters and tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmitters, contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer as the tire pressure warning valves
and transmitters may be damaged
if not handled correctly.
●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 pres-
sure warning valves and trans- mitters
When a tire is repaired with liquid
sealants, the tire pressure warning valve and transmitter may not operate
properly. If a liquid sealant is used,
contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer or other qualified ser-
vice shop as soon as possible. After use of liquid sealant, make sure to
replace the tire pressure warning
valve and transmitter when repairing or replacing the tire. ( P.304)
