sponge or soft cloth, such as a
chamois.
zFor hard-to-remove marks, use
car wash soap and rinse thor-
oughly with water.
zWipe away any water.
zWax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean sur-
face, apply wax when the vehicle body
is cool.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors.
Start washing from the front of the vehi-
cle. Extend the mirrors before driving.
●Brushes used in automatic car
washes may scratch the vehicle sur-
face, parts (wheel, etc.) and harm
your vehicle’s paint.
●In certain automatic car washes, the
rear spoiler may interfere with
machine operation. This may prevent
the vehicle from being cleaned prop-erly or result in damage to the rear
spoiler.
■High pressure car washes
As water may enter the cabin, do not
bring the nozzle tip near the gaps
around the doors or perimeter of the
windows, or spray these areas continu-
ously.
■When using a car wash
If the door handle becomes wet while
the electronic key is within the effective
range, the door may lock and unlock
repeatedly. In that case, follow the fol-
lowing correction procedures to wash
the vehicle:
●Place the key in a position 2 m (6 ft.)
or more separate from the vehicle
while the vehicle is being washed.
(Take care to ensure that the key is
not stolen.)
●Set the electronic key to battery-sav-
ing mode to disable the smart entry &
start system. (→P.110)
■Wheels and wheel ornaments
●Remove any dirt immediately by using
a neutral detergent.
●Wash detergent off with water immedi-
ately after use.
●To protect the paint from damage,
make sure to observe the following
precautions.
• Do not use acidic, alkaline or abrasive
detergent
• Do not use hard brushes
• Do not use detergent on the wheels
when they are hot, such as after driv-
ing or parking in hot weather
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repel-
lent coating (if equipped)

6-1. Maintenance and care
WARNING
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps
into the raindrop sensor
■Precautions regarding the
exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled sufficiently, as touching a hot
exhaust pipe can cause burns.
■Precaution regarding the rear
bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is
chipped or scratched, the system may malfunction. If this occurs, consult with any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer.
NOTICE
■To prevent paint deterioration and corrosion on the body and components (aluminum wheels,
etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on
the paint surface
• If dead insects, insect droppings or
bird droppings are present on the paint surface
• After driving in an area contami- nated with soot, oily smoke, mine dust, iron powder or chemical sub-
stances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gas- oline are spilled on the paint sur-face
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corrod-ing, remove any dirt and store in a
place with low humidity when stor- ing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard
brush. This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■To prevent damage to the wind-shield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver side wiper arm upward first, and repeat for the passenger side. When
returning the wipers to their original position, do so from the passenger side first.
■When using an automatic car wash
Set the wiper switch to the off posi- tion. If the wiper switch is in “AUTO”, the wipers may operate and the wiper
blades may be damaged.

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.

6-4. Do-it-yourself maintenance
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.
z 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.322,
357)
z 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.325)
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.

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
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.
• Near a TV tower, electric power plant,

noise. • When carrying a portable radio, cellu-lar 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 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.283)
■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.281)
