Jeep Wrangler2018, Owner'S Manual, Page: 347 / 608

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 when the engine is running. This is in
violation of most state and federal fire regulations and
may cause the MIL to turn on.
•
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.
CAUTION!
•
Damage to the fuel system or emission control sys-
tem 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 1/4 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.
