can help reduce excessive
fuel consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing
so will help to reduce the bur-
den on the air conditioning
system and reduce fuel con-
sumption as well.
In winter: Avoid excess heat-
ing. Use the seat heater (if
equipped) or steering heater
(if equipped) to minimize the
need for cabin heating
(P.342).
 Using eco air conditioning
mode, this helps curb fuel
consumption even with the air
conditioning system turned
on. ( P.326, 334)
Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to reduced fuel economy. Install-
ing a large roof rack will also reduce fuel economy.

WARNING
The fuel cell unit compartment
contains many mechanisms and
fluids that may move suddenly,
become hot, or become electri-
cally energized. To avoid death or
serious injury, observe the follow-
ing precautions.
■When working on the fuel cell
unit compartment
●Be careful not to touch the high-
voltage parts or hydrogen-
related parts.
●Make sure that the “READY”
indicator is off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the
motor, inverter, radiator, etc.
right after driving as they may
be hot. Coolant and other fluids
may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the fuel cell unit com-
partment.
ItemsParts and tools●Do not smoke, cause sparks or
expose an open flame to the 12-
volt battery. 12-volt battery
fumes are flammable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid
can harm your hands or eyes
and damage painted surfaces. If
fluid gets on your hands or in
your eyes, flush the affected
area with clean water immedi-
ately.
If you still experience discom-
fort, consult a doctor.
●Never touch, disassemble,
remove or replace the high-volt-
age parts, cables and their con-
nectors. It can cause severe
burns or electric shock that may
result in death or serious injury.
■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 fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.398)
■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
motor wear due to dirt in the air.

Maintenance and care
Check if the treadwear indica-
tors are showing on the tires.
Also check the tires for uneven
wear, such as excessive wear
on one side of the tread. New tread
Worn tread
Treadwear indicator
The location of treadwear indicators
is shown by a “TWI” or “ ” mark,
etc., molded into the sidewall of
each tire. Replace the tires if the treadwear
indicators are s
howing 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 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 with 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.
■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, whi chever 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 mentioned on
the sidewall of the tire. ( P.488)
■Tire types
●Summer tires
Summer tires are high-speed perfor-

accordance with mainte-
nance schedules and tread-
wear.
Checking tires

4047-3. Do-it-yourself maintenance
Owners Manual_USA_M62084_enmance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performanc
e as snow tires,
summer tires are inadequate for
driving on snow-covered or icy
roads. For driving on snow-covered
roads or icy roads, the use of snow
tires is recommended. When install-
ing snow tires, be sure to replace all
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions a s well as for use
year-round. All season tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
●Snow tires
For driving on snow-covered roads
or icy roads, we recommend using
snow tires. If you need snow tires,
select tires of the same size, con-
struction 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 stud ded tires without
first checking local regulations for
possible restrictions. Snow tires
should be installed on all wheels.
(  P.320)
■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
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 drive train 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 inflation 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.
