Avoid Using Contaminated Fuel; Bulk Fuel Storage - Diesel Fuel - Jeep Grand Cherokee 2018 Manual

NOTE:
There is no fuel filler cap. A flapper door inside
the filler pipe seals the system.
3. Insert the fuel nozzle fully into the filler pipe –
the nozzle opens and holds the flapper door
while refueling.
4. Fill the vehicle with fuel – when the fuel
nozzle "clicks" or shuts off the fuel tank is full.
5. Wait five seconds before removing the
nozzle to allow fuel to drain from the nozzle.
6. Remove the fuel nozzle and close the fuel
door.
Emergency Fuel Can Refueling
Most fuel cans will not open the flapper door.
A funnel is provided to open the flapper door to
allow emergency refueling with a fuel can.
1. Retrieve funnel from the spare tire kit.

3. Pour fuel into funnel opening.
4. Remove funnel from filler pipe, clean off prior
to putting back in the spare tire kit.
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 "Mal-
function Indicator Light" to turn on.
WARNING! (Continued)
• A fire may result if fuel is pumped into a
portable container that is inside of a ve-
hicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not
"top off" the fuel tank after filling.

Avoid Using Contaminated Fuel

Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel sys-
tem. Proper maintenance of the engine fuel filter
and fuel tank is essential. Refer to "Dealer
Service" in "Servicing And Maintenance" for
further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance
of the stored fuel is also essential. Fuel contami-
nated with water will promote the growth of
"microbes." These microbes form "slime" that
will clog the fuel filtration system and lines. Drain
condensation from the supply tank and change
the line filter on a regular basis.
NOTE:
When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
