Loose Fuel Filler Cap Message - Dodge Challenger 2016 Operating Information Manual

NOTE:
When removing the fuel filler cap, lay the
cap tether in the hook, located on the fuel
filler door.
CAUTION!
• Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
• A poorly fitting fuel filler cap could let
impurities into the fuel system.
• A poorly fitting fuel filler cap may cause the
"Malfunction Indicator Light (MIL)" to turn
on.
• To avoid fuel spillage and overfilling, do not
"top off" the fuel tank after filling. When the
fuel nozzle "clicks" or shuts off, the fuel
tank is full.
WARNING!
• Never have any smoking materials lit in or
near the vehicle when the gas cap is
removed or the tank is being filled.
• Never add fuel to the vehicle when the
engine is running.
• A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always
place gas containers on the ground while
filling.
NOTE:
• When the fuel nozzle "clicks" or shuts off,
the fuel tank is full.
• Tighten the gas cap until you hear a
"clicking" sound. This is an indication
that the gas cap is tightened properly. The
MIL in the instrument cluster may turn on
if the gas cap is not secured properly.
Make sure that the gas cap is tightened
each time the vehicle is refueled.

Loose Fuel Filler Cap Message

If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a "gASCAP" message will display
in the odometer or a "Check Gascap" message
will display in the Driver Information Display
(DID). If this occurs, tighten the fuel filler cap
properly and press the TRIP ODOMETER but-
ton to turn off the message. If the problem
continues, the message will appear the next
time the vehicle is started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the MIL. Refer to
"Onboard Diagnostic System" in "Maintaining
Your Vehicle" for further information.
