Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty sur-
faces with a cloth dampened with
lukewarm water.
 If dirt cannot be removed, wipe it
off with a soft cloth dampened
with neutral detergent diluted to
approximately 1%.
Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent
and water.
■Shampooing the carpets
There are several commercial foaming-
type cleaners available. Use a sponge or brush to apply the foam. Rub in over-lapping circles. Do not use water. Wipe
dirty surfaces and let them dry. Excellent results are obtained by keeping the car-pet as dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts periodically for exces-
sive wear, fraying or cuts.
NOTICE
■When using a high pressure car wash
●Vehicles with rear view monitor sys-tem: When washing the vehicle, do not spray the camera or its sur-
rounding area directly with a high pressure washer. Shock applied from high pressure water may
cause the device to not operate normally.
●Vehicles with Toyota Safety Sense: Do not spray water directly on the radar which is equipped behind the
emblem. Otherwise it may cause the device to be damaged.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-tured cover), connectors or the fol-
lowing parts. The parts may be damaged if they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi-cles body. Otherwise resin section,
such as moldings and bumpers, may be deformed and damaged. Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of the
windshield continuously. If water enters the air conditioning system intake located near the lower part of
the windshield, the air conditioning system may not operate correctly.
●Do not wash the underside of the vehicle using a high pressure car washer.

■Where to go for maintenance ser-
vice?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service opera- tions as well as other inspections and repairs be carried out by authorized
Toyota retailers or Toyota authorized repairers, or any reliable repairers. For repairs and services covered by your
warranty, please visit an authorized Toyota retailer or repairer, who will use genuine Toyota parts in repairing any
difficulties you may encounter. There can also be advantages in utilizing authorized Toyota retailers or repairers
for non-warranty repairs and services, as members of the Toyota network will be able to expertly assist you with any
difficulties you may encounter.
Your Toyota retailer or Toyota authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance on your vehicle reliably and economi-
cally due to their experience with Toyota vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance
schedule.
For full details of your maintenance
schedule, read the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are
easy to do yourself if you have a little
mechanical ability and a few basic
automotive tools.
Note, however, that some maintenance
tasks require special tools and skills.
These are best performed by qualified
technicians. Even if you’re an experi-
enced do-it-yourself mechanic, we rec-
ommend that repairs and maintenance
be conducted by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer. Any authorized
Toyota retailer or repairer will keep a
record of maintenance, which could be
useful should you ever require War-
ranty Service. Should you choose to
select a qualified and equipped profes-
sional other than an authorized Toyota
repairer to service or maintain your
vehicle, we recommend that you

molded into the sidewall of each tire.
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 retailer or Toyota authorized repairer, or any reliable
repairer.
■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 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.
■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 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.
●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.
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 help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
When rotating front and rear tires which
have different tire inflation pressures,
do not fail 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 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)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance 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. (Ways of coping: P.320,
355)
 When “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is a known level of low tire pres-
sure with the appearance of the tire due
to pressure suddenly lowering. (Ways
of coping: P.323)
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.
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.

●When tire inflation pressure declines rapidly for example when a tire has burst, the not to able detect.
■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 pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( P.281)
■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 stays on to indicate a system malfunc-
tion.
Installing tire pressure warn-
ing valves and transmitters
NOTICE
■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, corrode the valve, and cause sticking and air leaks.
●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 as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when
replacing the tire. ( P.279)

information display again to select “Identifying Each Wheel & Position”. ( P.281)
●If ID code registration has been can- celed, the tire pressure warning light
will blink for approximately 1 minute when the engine switch is turned to ON mode and then illuminate. The tire
pressure warning system will be oper- ational when the tire pressure warning light turns off.
●If the warning light does not turn off even after several minutes have
elapsed, ID code registration may not have been canceled correctly. To can-cel registration, perform the ID code
registration start procedure again and then turn the engine switch off before driving.
■If ID codes are not registered prop-
erly
●In the following situations, ID code
registration may take longer than usual to be completed or may not be possible. (Usually, the vehicle will
need to be driven for approximately 10 to 30 minutes to complete ID code registration.)
If ID code registration is not complete after driving for approximately 30 min-utes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer than normal to complete registration.
• If the vehicle is backed up while per- forming registration, data collected during registration will be cleared, and
it will take longer than normal to com- plete.• If the vehicle is driven in heavy traffic
or another situation where other vehi- cles are driven close by, it may take time for the system to recognize the
tire pressure warning valve and trans- mitters of your vehicle over those of other vehicles.
• If a wheel with a tire pressure warning valve and transmitter installed is inside or near the vehicle, registration
of the ID codes for the installed
wheels may not be possible.
If ID registration is not complete after
driving for approximately 1 hour, park
the vehicle in a safe place for approxi-
mately 20 minutes and then perform the
ID code registration procedure again.
●In the following situations, ID code registration will not be started or was
not completed properly and the sys- tem will not operate properly. Perform the ID code registration procedure
again. • If, when attempting to start ID code registration, the tire pressure warning
light does not blink slowly 3 times. • If, when the vehicle has been driven for about 10 minutes after performing
ID code registration, the tire pressure warning light blinks for approximately 1 minute and then illuminates.
●If ID code registration cannot be com-pleted after performing the above pro-
cedure, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
Your vehicle is equipped with tire
pressure warning system with the
function to have ID codes regis-
tered for a second wheel set, for
example a winter set, by any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
After registration of a second wheel
set, either of these two wheel sets
can be selected for usage with the
tire pressure warning system.

Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drive train
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Instructions for checking tire infla-tion pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation pressure reading.
●Always use a tire pressure gauge.It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
WARNING
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire dam-age
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.
