●Some settings cannot be changed
while driving. When changing set-
tings, park the vehicle in a safe
place.

WARNING
■Cautions during setting up
the display
If the hybrid system is operating
when changing the display set-
tings, ensure that the vehicle is
parked in a place with adequate
ventilation. In a closed area such
as a garage, exhaust gases
including harmful carbon monox-
ide (CO) may collect and enter
the vehicle. This may lead to
death or a seri ous health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery dis-
charge, ensure that the hybrid
system is operating while setting
up the display features.

Turn the power switch off and
ensure that all the doors and
windows are closed.
 Confirm the type of fuel.
■Fuel types
 P. 5 4 2
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unle aded fuel pumps.
Opening the fuel tank
cap
The fuel tank of your vehicle
has a special structure,
which requires a reduction
in fuel tank pressure before
refueling. After the opener
switch has been pressed, it
will take several seconds
until the vehicle is ready for
refueling.

WARNING
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure
to do so may result in death or
serious injury.
●After exiting the vehicle and
before opening the fuel door,
touch an unpainted metal sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing from static electricity can
cause fuel vapors to ignite while
refueling.
●Always hold the grips on the
fuel tank cap and turn it slowly
to remove it.
A whooshing sound may be
heard when the f uel tank cap is
loosened. Wait until the sound
cannot be heard before fully
removing the cap. In hot
weather, pressurized fuel may
spray out of the filler neck and
cause injury.
●Do not allow anyone that has
not discharged static electricity
from their body to come close to
an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that
are harmful if inhaled.
●Do not smoke while refueling
the vehicle.
Doing so may cause the fuel to
ignite and cause a fire.
●Do not return to the vehicle or
touch any person or object that
is statically charged. This may
cause static electricity to build
up, resulting in a possible igni-
tion hazard.
■When refueling
Observe the following precautions
to prevent fuel overflowing from
the fuel tank:
●Securely insert the fuel nozzle
into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.

4466-1. Maintenance and care
Owners Manual_USA_M0C052_en
WARNING
■Water in the vehicle
Do not get any of the SRS compo-
nents or wiring in the vehicle inte-
rior wet. ( P. 3 6 )
An electrical malfunction may
cause the airbags to deploy or not
function properly, resulting in
death or serious injury.
■Cleaning the interior (espe-
cially instrument panel)
Do not use a polis h wax or polish
cleaner. The instrument panel
may reflect off the windshield,
obstructing the dr iver’s view and
leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types
of detergent, as they may dis-
color the vehicle interior or
cause streaks or damage to
painted surfaces:
• Areas other than the seats and steering wheel: Organic sub-
stances such as benzene or
gasoline, alkaline or acidic solu-
tions, dye, and bleach
• Seats: Alkaline or acidic solu- tions, such as thinner, benzene,
and alcohol
• Steering wheel: Organic sub- stances, such as thinner, and
cleaner that contains alcohol
●Do not use a polish wax or pol-
ish cleaner. The instrument
panel’s or other interior part’s
painted surface may be dam-
aged.
■Preventing damage to leather
surfaces
Observe the following precautions
to avoid damage to and deteriora-
tion of leather surfaces:
●Remove any dust or dirt from
leather surfaces immediately.
●Do not expose the vehicle to
direct sunlight for extended peri-
ods of time. Park the vehicle in
the shade, especially during
summer.
●Do not place items made of
vinyl, plastic, or containing wax
on the upholstery, as they may
stick to the leather surface if the
vehicle interior heats up signifi-
cantly.
■Water on the floor
Do not wash the v ehicle floor with
water.
Vehicle systems such as the
audio system may be damaged if
water comes into contact with
electrical components such as the
audio system above or under the
floor of the vehicle. Water may
also cause the body to rust.
■When cleaning the inside of
the windshield
Do not allow glass cleaner to con-
tact the lens. Also, do not touch
the lens. ( P.225)
■Cleaning the inside of the
back window
●Do not use a gla ss cleaner to
clean the back window, as this
may cause damage to the back
window defogger heater wires
or antenna. Use a cloth damp-
ened with lukewarm water to
gently wipe the window clean.
Wipe the window in strokes run-
ning parallel to the heater wires
or antenna.

Maintenance and care
1 Take out the mechanical key.
2 Remove the cover.
To prevent damage to the key,
cover the tip of the flathead screw-
driver with a tape.
3Remove the depleted battery.
Insert a new battery with the “+” ter-
minal facing up.
Replacing the batteryWARNING
■Removed battery and other
parts
These parts are small and if swal-
lowed by a child, they can cause
choking. Keep away from chil-
dren. Failure to do so could result
in death or serious injury.
■Battery precautions
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not swallow the battery.
Doing so may cause chemical
burns.
●A coin battery or button battery
is used in the electronic key. If a
battery is swa llowed, it may
cause severe chemical burns in
as little as 2 hours and may
result in death or serious injury.
●Keep away new and removed
batteries from children.
●If the cover cannot be firmly
closed, stop using the electronic
key and stow the key in the
place where children cannot
reach, and then contact your
Toyota dealer.
●If you accidentally swallow a
battery or put a battery into a
part of your b ody, get emer-
gency medical attention imme-
diately.
■To prevent battery explosion
or leakage of flammable liq-
uid or gas
●Replace the battery with a new
battery of the same type. If a
wrong type of battery is used, it
may explode.

Oil viscosity (0W-20 is explained
here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil
which allows cold startability.
Oils with a lower value before
the W allow for easier starting
of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature.
How to read oil container label:
The International Lubricant Specification Advisory Commit-
tee (ILSAC) Certification Mark is
added to some oil containers to
help you select the oil you
should use.

■Non-recommendation of the
use of gasoline containing MMT
Some gasoline contains an octane
enhancing additive called MMT
(Methylcyclopentadienyl Manga-
nese Tricarbonyl).
Toyota does not recommend the use
of gasoline that contains MMT. If
fuel containing MMT is used, your
emission control system may be
adversely affected.
The malfunction indicator lamp on
the instrument cluster may come on.
If this happens, contact your Toyota
dealer for service.
■If your engine knocks
●Consult your Toyota dealer.
●You may occasionally notice light
knocking for a short time while
accelerating or dr iving uphill. This
is normal and there is no need for
concern.
NOTICE
■Notice on fuel quality
●Do not use impro per fuels. If
improper fuels are used, the
engine will be damaged.
●Do not use leaded gasoline.
Leaded gasoline can cause
damage to your vehicle’s three-
way catalytic converters caus-
ing the emission control system
to malfunction.
●Do not use gasohol other than
the type previously stated.
Other gasohol may cause fuel
system damage or vehicle per-
formance problems.
●Using unleaded gasoline with
an octane number or rating
lower than the l evel previously
stated will cause persistent
heavy knocking.
At worst, this will lead to engine
damage.
■Fuel-related poor driveability
If poor driveability (poor hot start-
ing, vaporization, engine knock-
ing, etc.) is encountered after
using a different type of fuel, dis-
continue the use of that type of
fuel.
■When refueling with gasohol
Take care not to spill gasohol. It
can damage your vehicle’s paint.
