Before driving
■
Identifying flex-fuel vehicles
■ Fuel tank capacity
Approximately 26.4 gal. (100 L, 22.0 Imp. gal.)
■ E85 Fueling Stations (Flex-fuel vehicles)
E85 fueling stations and fuel pumps can be identified by the indication “E85
85% Ethanol”. For more information about fueling stations, please refer to
the U.S. Department of Energy Web site.
http://www.eere.energy.gov/afdc/infrastructure/locator.html
■ Refueling (Flex-fuel vehicles)
Observe the following precautions when switching fuels, in order to maintain
starting and driving performance.
●Do not change fuels when the fuel level is 1/4 or less.
● Always add at least 2.6 gal. (10 L) of fuel.
● After filling up with fuel, warm up the engine or drive the vehicle for at
least 5 minutes or 7 miles (11 km).
● Do not accelerate rapidly immediately after refueling.
●Flex-fuel vehicles can be identified by
the fuel tank cap, which is marked
“FLEXFUEL E85/GASOLINE”.

Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.Turn the engine switch to the ACC or LOCK position.
Restart the engine.

NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.

Vehicle specifications
Fuel infor mation
■Fuel tank opening fo r unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
Gasoline engine
Your vehicle must use only unleaded gasoline.
Select octane rating 87 (Research Octane Number 91) or higher. The
use of unleaded fuel with an octane rating lower than 87 may result
in engine knocking. Persistent kno cking can lead to engine damage.
At minimum, the gasoline you use should meet the specifications
of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
Flex-fuel engine
Your vehicle must use only unleaded gasoline, E85, or a blend of the
two fuels.
Unleaded gasoline (Octane rating 87 [Research Octane Number 91]
or higher), E85, or a blend of these two fuels is required for optimum
engine performance.
The use of unleaded gasoline with an octane rating lower than 87
may result in engine knocking. Persistent knocking can lead to
engine damage.
The use of fuel with an ethanol concentration in excess of 85% will
have a negative impact on driv ing performance and can cause
damage to the fuel system components.
At minimum, the gasoline you us e should meet the specifications
of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.
At minimum, the E85 you use should meet the specifications of
ASTM D5798 in the U.S.A.
