2012 JEEP GRAND CHEROKEE fuel cap release

WARNING!
Do not use alcohol or gasoline as a fuel-
blending agent. They can be unstable under
certain conditions and hazardous or explosive
when mixed with diesel fuel.
Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the accu-
mulated water from the fuel/water separator
using the provided fuel/water separator drain. If
you buy good quality fuel and follow the cold
weather advice above, fuel conditioners should
not be required in your vehicle. If available in
your area, a high cetane “premium” diesel fuel
may offer improved cold-starting and warm-up
performance.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located behind the locking fuel
filler door, on the driver’s side of the vehicle. If
the gas cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
1. Press the fuel filler door release switch (lo-
cated under the headlamp switch). 2. Open the fuel filler door, and remove the fuel
filler cap.
CAUTION!
•
Damage to the fuel system or emission
control system could result from using an
improper fuel cap (gas 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.
• A poorly fitting gas cap may cause the MIL
to turn on.
• To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or
near the vehicle when the gas cap is re-
moved 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 mal-
function indicator light to turn on.

WARNING!(Continued)
• 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 about one-quarter
turn until you hear one click. This is an
indication that the cap is properly tight-
ened.
• If the gas cap is not tighten properly, the
MIL will come on. Be sure the gas cap is
tightened every time the vehicle is refu-
eled.

damaged, a loose gascap indica-
tor will display in the EVIC telltale
display area. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Under- standing Your Instrument Panel” for further in-
