WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Make sure that “POWER ON”
on the meter and the “READY”
indicator are both off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the
engine, power control unit, radi-
ator, exhaust manifold, etc. right
after driving as they may be hot.
Oil and other fluids may also be
hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
ItemsParts and tools●Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is OFF.
With the power switch in ON, the
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.508)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc., from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

■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 internal damage
●A tire goes flat repeatedly or can-
not be properly repaired due to
the size or location of a cut or
other damage
If you are not sure, consult your
Toyota dealer.
■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 (vehicles with
195/50R19 tires)
Generally, low profile tires will wear
more rapidly and tire grip perfor-
mance 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 appropri-
ate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either the front axle or
the rear axle, whic hever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum
cold tire inflation pressure men-
tioned on the sidewall of the tire.
(  P.609)
■Tire types
●Summer tires
Summer tires are high-speed per-
formance tires best suited to high-
way driving under dry conditions.
Since summer tires do not have
the same traction performance as
snow tires, summer tires are inad-
equate for driving on snow-cov-
ered or icy roads. For driving on
snow-covered roads or icy roads,
the use of snow tires is recom-
mended. When installing snow
tires, be sure to replace all four
tires.
●All season tires
All season tires are designed to
provide better traction in snow and
to be adequate for driving in most
winter conditions as well as for
use year-round. All season tires,
however, do not have adequate
traction performance compared
with snow tires in heavy or loose
snow. Also, all season tires fall
short in acceleration and handling
performance compared with sum-
mer tires in highway driving.
●Snow tires
For driving on snow-covered
roads or icy roads, we recom-
mend using snow tires. If you
need snow tires, select tires of the
same size, construction and load
capacity as the originally installed
tires. Since your vehicle has radial
tires as original equipment, make
sure your snow tires also have
radial construction. Do not install
studded tires without first checking
local regulation s for possible
restrictions. Snow tires should be
installed on all wheels. ( P.429)

Maintenance and care
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.
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 initia lize the tire pres-
sure warning system after tire rota-
WARNING
■When inspecting or replacing
tires
Observe the following precautions
to prevent accidents.
Failure to do so may cause dam-
age to parts of the drivetrain as
well as dangerous handling char-
acteristics, which may lead to an
accident resulting in death or seri-
ous injury.
●Do not mix tires of different
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than
those recommended by Toyota.
●Do not mix differently con-
structed 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 previ-
ously.
NOTICE
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
These conditions may cause
losses in tire in flation pressure,
reducing the cushioning ability of
the tires. In addition, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.
■Low profile tires (vehicles
with 195/50R19 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 infla-
tion pressure. If tires are under-
inflated, they may be damaged
more severely.
●Avoid potholes, uneven pave-
ment, curbs and other road haz-
ards. Failure to do so may lead
to severe tire and wheel dam-
age.
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.

■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)
The tire pressure warning light
comes on and a buzzer sounds
when the tire infl ation pressure
becomes low due to natural air
leakage or outside temperature. (Ways of coping:
P.561, 605)
 When “Immediately Check
tire when Safe” is displayed
(Emergency Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low suddenly due to a
blowout. (Ways of coping: P.561,
574)
However, the sys tem 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.
( P.161)
The illustration us ed is intended as
an example, and may differ from
the image that is actually displayed
on the multi-information display.
■How to change the unit
1 Park the vehicle in a safe
place and turn the power
switch off.
Changing the unit cannot be per-
formed while the vehicle is moving.
2Start the hybrid system.

■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 dis-
play the tire inflation pressure
after the power switch is turned to
ON.
It may also take a few minutes to
display the tire in flation 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
pressure warning system may
not operate properly
●In the following cases, the tire pressure 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.
• 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 speci-
fied level.
• If wheel without 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, gas station, radio station,
large display, airport 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 in formation is not cor-
rectly displayed due to the radio
wave conditions, the display may be
corrected by changing the location
of the vehicle as the radio wave
conditions may change.
●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.

A message indicating that wheel
position registration is being per-
formed will be displayed on the
multi-information di splay. “---” will
be displayed for the tire inflation
pressure of each tire and wheel
position registration will begin.
8 Drive straight (with occa-
sional left and right turns) at
approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When wheel position registration is
complete, a message indicating
that registration has been com-
pleted and the inflation pressure of
each tire will be displayed on the
multi-informat ion display.
Even if it is not possible to drive
continuously at approximately 25
mph (40 km/h) or more, registration
can be completed by driving for a
long time. However, if registration
does not complete after driving for
1 hour or more, park the vehicle in
a safe place and leave it with the
power switch in ON for approxi-
mately 15 minutes or more, and
then perform the driving procedure
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.
■Wheel position registration pro-
cedure
●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 registration will resume
and it will not be necessary to
restart the procedure.
●While the position of each wheel is
being determined and the inflation
pressures are not being dis-
played, if the inflation pressure of
a tire drops, the tire pressure
warning light will come on.

5207-3. Do-it-yourself maintenance
■If the wheel position cannot be
registered easily
●In the following situations, wheel
position registration may take lon-
ger than usual to be 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 wheel position registration does
not complete afte r 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.
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 set-
ting procedure by selecting speci-
fied 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 infla- tion 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 wa rning system oper-
ates based on this tire inflation
pressure.
■Setting by selecting a spec-
ified tire inflation pressure
1 Start the hybrid system.
The tire inflation pressure cannot
be set while the vehicle is moving.
