Jeep Wrangler: REFUELING THE VEHICLE — GASOLINE ENGINE (IF EQUIPPED) / Fuel Filler Cap
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.

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
“Malfunction Indicator Light” 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 “Malfunction 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.
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.
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...
Other information:
Your vehicle is equipped with a Selective
Catalytic Reduction (SCR) system to meet the
very stringent diesel emissions standards
required by the Environmental Protection Agency.
The purpose of the SCR system is to reduce levels
of NOx (oxides of nitrogen emitted from engines)
that are harmful to our health and the
environment to a near-zero level...
The fuel/water separator housing is located
inside the left frame rail in front of the fuel tank.
The best access to this water drain valve is from
under the vehicle.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running...
