2023 JEEP GLADIATOR open gas tank

192STARTING AND OPERATING
3. Fully insert the gasoline nozzle into the filler pipe. Fill the vehicle with fuel.
4. When the fuel nozzle “clicks” or shuts off, the fuel tank is full. Wait five seconds before
removing the fuel nozzle to allow excess fuel to
drain from nozzle.
5. Remove gasoline nozzle, reinstall fuel cap and close the fuel filler door.
NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap about a quarter turn
until you hear one click. This is an indication that
the cap is properly tightened.
If the fuel filler cap is not tightened properly, the
MIL will come on. Be sure the cap is tightened
every time the vehicle is refueled.
LOOSE FUEL FILLER CAP MESSAGE
After fuel has been added, the vehicle diagnostic
system can determine if the fuel filler cap is
possibly loose, improperly installed, or damaged. If
the system detects a malfunction, the “gASCAP”
message will display in the odometer display.
Tighten the gas cap until a "clicking" sound is heard. This is an indication that the gas cap is
properly tightened. Push the odometer reset
button to turn the message off. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged
cap. If the problem is detected twice in a row, the
system will turn on the MIL. Resolving the problem
will turn the MIL off.
REFUELING THE VEHICLE — DIESEL ENGINE
(IF EQUIPPED)
The fuel filler cap is located on the driver's side of
the vehicle. If the fuel filler cap is lost or damaged,
be sure the replacement cap is the correct one for
this vehicle.

1. Open the fuel filler door.

Fuel Filler Door

WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light (MIL) to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper
fuel filler cap. A poorly fitting cap could let
impurities into the fuel system. Also, a poorly
fitting aftermarket cap can cause the Malfunc -
tion Indicator Light (MIL) to illuminate, due to
fuel vapors escaping from the system.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
