■Fuel types
(
P. 601)
■ E85 Fueling Stations (Flex-fuel vehicles)
E85 fueling stations and fuel pumps can be identified by the in dication “E85
85% Ethanol”. For more information about fueling stations, plea se refer to the
U.S. Department of Energy Web site.
http://www.afdc.energy.gov/afdc/locator/stations/
■ 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.
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that

2224-4. 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, tou ch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks re sulting from
static electricity can cause fuel vapors to ignite while refuel ing.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosen ed.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out 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 p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing f rom the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.
■ When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.
