■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ If the fuel level gauge is malfunctioning
The malfunction indicator lamp may illuminate if the fuel level gauge is mal-
functioning. (A malfunction may be detected and the malfunction indicator
lamp may illuminate erroneously in some situations, such as whe n the vehicle
is refueled repeatedly when the fuel tank is nearly full.)
Opening the fuel tank cap
Perform the following steps to open the fuel tank cap:

NOTICE
■Cleaning detergents
● Do not use the following types of detergent, as they may discol or the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasol ine,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco-
hol
● Do not use polish wax or polish cleaner. The instrument panel's or other
interior part's painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces:
● Remove any dust or dirt from leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended perio ds of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if wate r comes
into contact with electrical components such as the audio syste m above or
under the floor of the vehicle. Water may also cause the body to rust.
■ Cleaning the inside of the rear window
● Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires. Use a cloth da mpened
with lukewarm water to gently wipe the window clean. Wipe the w indow in
strokes running parallel to the heater wires.
● Be careful not to scratch or damage the heater wires.

When trouble arises

When replacing the 12-volt battery
●Use a Central Degassing type 12-volt battery (European regulati ons).
● Use a 12-volt battery that the case size is same as the previou s one (LN0),
20 hour rate capacity (20HR) is equivalent (35Ah) or greater, and perfor-
mance rating (CCA) is equivalent (240A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly se cured.
• If the 20 hour rate capacity is low, even if the time period w here the vehi-
cle is not used is a short time, the 12-volt battery may discharge and the
hybrid system may not be able to start.
● Use a 12-volt battery with a handle. If a 12-volt battery witho ut a handle is
used, removal is more difficult.
For details, consult your Toyota dealer. ● After replacing, firmly attach the follow-
ing items to the exhaust hole of the 12-
volt battery.
Use the exhaust hose that was
attached to the 12-volt battery before
replacing and confirm that it is firmly
connected to the hole section of the
vehicle.

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 wi th a lower value before the W allow
for easier starting of the engine in cold weather.
• The 20 in 0W-20 indicates the vi scosity characteristic of the oil
when the oil is at high temperature. An oil with a higher visco sity
(one with a higher value) may be better suited if the vehicle i s
operated at high speeds, or un der extreme load conditions.
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.

NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engi ne will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way ca talytic
converters causing 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 performan ce
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine k nocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
