■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is your vehicle low on gas?
If it is, refuel the vehicle immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after taking several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■ Front passenger detection sensor and passenger seat belt reminder

Pushing the tire pressure warning reset switch does not turn off the tire
pressure warning light.
■The tire pressure warning light may turn on due to natural causes

■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.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
■ Fuel quality
In very few cases, driveability problems may be caused by the brand of f\
uel
you are using. If driveability problems persist, try changing the brand of fuel.
If this does not correct the problem, consult your Toyota dealer.
■ Gasoline quality standards
●Automotive manufacturers in the US, Europe and Japan have developed
a specification for fuel quality called World-Wide Fuel Charter (WWFC)
that is expected to be applied worldwide.
● The WWFC consists of four categories that are based on required emis-
sion levels. In the US, category 4 has been adopted.
● The WWFC improves air quality by lowering emissions in vehicle fleets,
and customer satisfaction through better performance.
■ E85 fuel (Flex-fuel vehicles)
●E85 fuel is a blend of 85% ethanol and 15% gasoline. However, E85
does not necessarily contain 85% ethanol. The ethanol content of E85 is
required by ASTM to be between 70% and 85%. For example, in cold cli-
mates the ethanol content of E85 may be reduced during the winter
months to maintain cold weather starting performance.
● E85 has less energy per gallon than gasoline, so you will need to fill your
fuel tank more frequently when using E85.
● The number of fuel stations that sell E85 fuel is limited. For more infor-
mation about fueling stations, please refer to the U.S. Department of
Energy Web site.
