Filling the Tank

Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
Turn off the engine when
refueling.
Keep sparks, flames, and
smoking materials away
from fuel.
Do not leave the fuel pump
unattended.
Do not use a cell phone
while refueling.
Do not re-enter the vehicle
while pumping fuel.
Keep children away from
the fuel pump and never let
children pump fuel.

Warning (Continued)
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.
Van Shown, Pickup Similar
The green fuel cap is behind a
hinged door on the driver side of the
vehicle. On van and 4-cylinder
pickup models, the blue diesel
exhaust fluid cap is also behind the
fuel door. Do not remove both caps
at the same time.
For chassis-cab models, refuel the
front tank first, or in instances when
only a partial fuel fill is desired. An
automatic transfer mechanism will
maintain approximately equal fuel
levels in both tanks, so no switching
is required.
To remove the fuel cap, turn it
slowly to the left (counterclockwise).
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.
Be careful not to spill fuel. Wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
