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).

5468-2. Steps to take in an emergency
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.
To minimize the risk of fuel leakage when the engine stalls or
when an airbag inflates upon collision, the fuel pump shut off
system stops supply of fuel to 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.

● If you use gasohol in your vehicle, be sure that it has an octa ne rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methan ol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adv ersely
affected.

happens, contact your Toyota dealer for service.
■ Non-recommendation of the use of after-market fuel additives (Flex-fuel
vehicles)
Do not use any after-market fuel additives when repeatedly refu eling with
E85, as some after-market fuel additives are not compatible wit h E85.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time whi le accelerat-
ing or driving uphill. This is normal and there is no need for concern.
●

ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
