During the summer season, fuel ethanol may contain a maximum of 85%
denatured ethanol (Ed85) and 15% unleaded gasoline. The fuel ethanol
has a higher octane rating than unleaded regular or premium gasoline
and this allows the design of engines with greater efficiency and power.

Winter blends may contain up to 75% denatured ethanol (Ed75) and up
to 25% unleaded gasoline to enhance cold engine starts. Severely cold
weather may require additional measures for reliable starting.

Ethanol is more chemically active than gasoline. It corrodes some metals
and causes some plastic and rubber components to swell, break down or
become brittle and crack, especially when mixed with gasoline. Special
materials and procedures have been developed for flexible fuel vehicles
and the dispensers used by ethanol fuel providers.

WARNING: Flexible fuel components and standard unleaded
gasoline fuel components are not interchangeable. If your vehicle

is not serviced in accordance with flexible fuel vehicles procedures,
damage may occur and your warranty may be invalidated.

WARNING: When refueling always shut the engine off and
never allow sparks or open flames near the filler neck. Never

smoke while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.

WARNING: The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is

pumped into an ungrounded fuel container.

Refueling

WARNING: Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:

• Read and follow all the instructions on the pump island;

• Turn off your engine when you are refueling;

• Do not smoke if you are near fuel or refueling your vehicle;

• Keep sparks, flames and smoking materials away from fuel;

• Stay outside your vehicle and do not leave the fuel pump unattended

when refueling your vehicle — this is against the law in some places;

• Keep children away from the fuel pump; never let children pump fuel.

• Do not use personal electronic devices while refueling.
