Adding Fuel; Fuel Filler Cap (Gas Cap) - Jeep 2011 WK2 Grand Cherokee Owner's Manual

CAUTION!
The manufacturer requires that you must fuel
this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and
prohibits the use of Low Sulfur Highway Die-
sel fuel (500 ppm Sulfur maximum) to avoid
damage to the emissions control system.
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.

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.
