2018 JEEP CHEROKEE fuel pump

Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off theHVAC Blower Motor, Close the HVAC Circu-
lation Door
• Cut off battery power to the: – Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there
are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air bag
system is not there to protect you. Do not
modify the components or wiring, includ-
ing adding any kind of badges or stickers
to the steering wheel hub trim cover or the
upper right side of the instrument panel.
Do not modify the front bumper, vehicle
body structure, or add aftermarket side
steps or running boards.
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-

WARNING!
• Never add fuel when the engine is run-ning. This is in violation of most coun-
tries 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 emissioncontrol 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 after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.
• A poorly fitting fuel filler cap may cause
the MIL to turn on.
CAUTION!
• To avoid fuel spillage and overfilling, donot “top off” the fuel tank after filling.
• If fuel is spilled on surface on the paint,
clear it immediately to avoid damage the
paint.

Methanol
(Methyl) is used in a variety of concentrations
when blended with unleaded gasoline. You
may find fuels containing 3% or more metha-
nol along with other alcohols called cosol-
vents. Problems that result from using
methanol/gasoline are not the responsibility
of the manufacturer. While MTBE is an oxy-
genate made from Methanol, it does not have
the negative effects of Methanol.
WARNING!
Do not use gasolines containing Methanol.
Use of these blends may result in starting
and drivability problems and may damage
critical fuel system components.
Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from
a reputable supplier may reduce the risk of
exceeding this 15% limit and/or of receiving
fuel with abnormal properties. It should also
be noted that an increase in fuel consump-
tion should be expected when using ethanol-blended fuels, due to the lower energy con-
tent of ethanol. Problems that result from
using methanol/gasoline or E-85 ethanol
blends are not the responsibility of the
manufacturer.
CAUTION!
Use of fuel with Ethanol content higher
than 15% may result in engine malfunc-
tion, starting and operating difficulties,
and materials degradation. These adverse
effects could result in permanent damage
to your vehicle.
Clean Air Gasoline
Many gasolines are now being blended to
contribute to cleaner air, especially in those
areas where air pollution levels are high.
These new blends provide a cleaner burning
fuel and some are referred to as “reformu-
lated gasoline.”
The manufacturer supports these efforts to-
ward cleaner air. You can help by using these
blends as they become available.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on
compressed natural gas (CNG) or liquid pro-
pane (LP) may result in damage to the en-
gine, emissions, and fuel system compo-
nents. Problems that result from running
CNG or LP are not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricar-
bonyl (MMT) is a manganese containing me-
tallic additive that is blended into some gaso-
line to increase octane. Gasoline blended
with MMT provides no performance advan-
tage beyond gasoline of the same octane
number without MMT. Gasoline blended with
MMT reduces spark plug life and reduces
emission system performance in some ve-
hicles. The manufacturer recommends that
gasoline without MMT be used in your ve-
hicle. The MMT content of gasoline may not
be indicated on the gasoline pump; there-
fore, you should ask your gasoline retailer
whether or not his/her gasoline contains
MMT.
