Maintenance and care
 Remove dirt using a water
dampened soft cloth or syn-
thetic chamois.
 Wipe the surface with a dry
soft cloth to remove any
remaining moisture.
■Cleaning the areas with satin-
finish metal accents
The metal areas use a layer of real
metal for the surface. It is necessary
to clean them regularly. If dirty areas
are left uncleaned for long periods
of time, they may be difficult to
clean.
 Remove dirt and dust using a
vacuum cleaner.
 Wipe off any excess dirt and
dust with a soft cloth damp-
ened with diluted detergent.
Use a diluted water solution of
approximately 5% neutral wool
detergent.
Wring out any excess water
from the cloth and thoroughly wipe off all remaining traces
of detergent.
 Wipe the surface with a dry,
soft cloth to remove any
remaining moisture. Allow the
leather to dry in a shaded and
ventilated area.
■Caring for leather areas
Toyota recommends cleaning the
interior of the vehicle at least twice a
year to maintain t he quality of the
vehicle’s interior.
 Remove dirt and dust using a
vacuum cleaner.
 Wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
NOTICE
●Be careful not to scratch or
damage the heater wires.
■Cleaning the fr ont side win-
dows
Do not use any compound or

Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
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 posi-
tion information 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 equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
The tire pressure warning sys-
tem of this vehicle adopts a 2-
type warning system.
 When “Adjust Pressure” is
displayed (Normal Warning)
A warning with the tire pressure
warning light and warning buzzer
when there is an unknown level of
low tire pressure with the appear-
ance 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.
When “Immediately Check
Tire when Safe” is displayed
(Emergency Warning)
A warning with the tire pressure
warning light and warning buzzer
when there is a k nown level of low
tire pressure with the appearance
of the tire due to pressure suddenly
lowering.
However, the system may not be
able to detect sudden tire ruptures
(bursting, etc.).
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information 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.

●Performance may be affected in
the following situations.
• Near a TV tower, electric power
plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
• When carrying a portable radio, cellular 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
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.
When replacing tires or wheels,
tire pressure warning valves and
transmitters 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.
(  P.481)
■When replacing the tires and
wheels
If the ID code of the tire pressure
warning valve and transmitter is not
registered, 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 malfunction.

mitters
NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your
Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●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
pressure warning valves and
transmitters
When a tire is repa ired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer as soon as possible. After
use of liquid sealant, make sure to
replace the tire p ressure warning
valve and transmitter when repair-
ing or replacing the tire.

place for approximately 15 minutes
and then drive th
e vehicle again.
■When performing wheel posi-
tion registration
●Normally, wheel position registra-
tion can be completed within
approximately 30 minutes.
●Wheel position registration is per-
formed while driving at a vehicle
speed of approximately 25 mph
(40 km/h) or more.
■The initialization operation
●If the power switch is turned off
while registering the wheel posi-
tion, the next time the power
switch is turned to ON, the wheel
position registr ation will resume
and it will not be necessary to
restart the procedure.
●While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-information display, if
the inflation pres sure of a tire
drops, the tire pressure warning
light will come on.
■If the tire pressure warning sys-
tem is not registered properly
●In the following situations, wheel
position registration may take lon-
ger than usual to b e completed or
may not be possible.
• Vehicle is not driven at approxi-
mately 25 mph ( 40 km/h) or more
• Vehicle is driven on unpaved roads
If initialization does not complete
after driving for 1 hour or more, park
the vehicle in a safe place for
approximately 15 minutes and then
drive the vehicle again.
●If the vehicle is reversed during
wheel position registration, all
data collected until then will be
cleared. Perform driving again.
■When you need to setting
the tire pressure
In the following situations, it will
be necessary to perform the tire
inflation pressure setting proce-
dure of the tire pressure warning
system.
 When the specified tire infla-
tion pressure has changed,
such as due to carried load,
etc.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
If the tire inflation pressure has
been adjusted to the specified
level, perform the tire inflation
setting procedure by selecting
specified inflation pressure on
the multi-information display.
When the tire inflation pressure
is to be other than specified,
such as when tires other than
the specified size are used, etc.,
set the tire inflation pressure
using the current pressure.
Make sure to adjust the tire
inflation pressure of each tire to
the appropriate level before per-
forming tire pressure setting.
The tire pressure warning sys-
tem operates based on this tire
inflation pressure.
