all the instructions on the
fuel pump island.
Turn off the engine when

Warning (Continued)
Keep children away from
the fuel pump and never let
children pump fuel.
Fuel can spray out if the fuel
cap is opened too quickly.
This spray can happen if the
tank is nearly full, and is
more likely in hot weather.
Open the fuel cap slowly
and wait for any hiss noise
to stop, then unscrew the
cap all the way.

Driving and Operating
The fuel cap is behind a hinged fuel
door on the driver side of the
vehicle. Vehicles that have a
FlexFuel badge and a yellow fuel
cap can use either unleaded
gasoline or ethanol fuel containing
up to 85% ethanol (E85). See E85
or FlexFuel 0 318.
To remove the fuel cap, turn it
slowly counterclockwise.
If the vehicle is a dual fuel tank
chassis cab model, and it runs out
of fuel, refuel the front fuel tank first
to ensure a quick restart.
Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
Vehicle performance issues,
including engine stalling and
damage to the fuel system.
Fuel spills.
Potential fuel fires.
