204 Driving and Operating
Warning (Continued)
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.
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.
The fuel cap is behind the fuel door
on the passenger side of the
vehicle. To open the fuel door, push
and release the rearward center
edge of the door.
Turn the fuel cap counterclockwise
to remove. If the vehicle has E85
fuel capability, the fuel cap will be
yellow and state that E85 or
gasoline can be used. See E85 or
FlexFuel 0 203. While refueling,
hang the fuel cap from the hook on
the fuel door. Reinstall the cap by
turning it clockwise until it clicks.
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
surfaces as soon as possible. See
Exterior Care 0 280.
When replacing the fuel cap, turn it
clockwise until it clicks. Make sure
the cap is fully installed. The
diagnostic system can determine if
the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. See Malfunction
Indicator Lamp (Check Engine
Light) 0 118.
