2013 JEEP GRAND CHEROKEE fuel pump

Vehicles equipped with the Anti-Lock Brake
System (ABS), are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two sec-
onds. The light should then turn off unless the
parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.15. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock
Brake System (ABS). The light will
turn on when the ignition switch is
turned to the ON/RUN position and
may stay on for as long as four sec-
onds.
If the ABS light remains on or turns on while
driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the BRAKE warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock brakes. If the ABS light
does not turn on when the ignition switch is
turned to the ON/RUN position, have the light
inspected by an authorized dealer. 16. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear drive-
shafts are mechanically locked to-
gether forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation” in “Starting And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder
The fuel pump symbol points to the
side of the vehicle where the fuel
door is located.

•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking
power when you need it to prevent a colli-
sion. If you have been operating your vehicle
in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driv-
ing in mud, slush or similar conditions, check
the wheels for impacted material. Impacted
material can cause a wheel imbalance and
freeing the wheels of it will correct the
situation.
FUEL SAVER TECHNOLOGY
5.7L ENGINE ONLY – IF
EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine’s eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
This system may take some time to return to
full functionality after a battery disconnect.
POWER STEERING
3.6L And 5.7L EngineThe standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost. If for some reason the power assist is inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and dur-
ing parking maneuvers.
NOTE:
•
Increased noise levels at the end of the
steering wheel travel are considered nor-
mal and do not indicate that there is a
problem with the power steering system.
• Upon initial start-up in cold weather, the
power steering pump may make noise for
a short amount of time. This is due to the
cold, thick fluid in the steering system.
This noise should be considered normal,
and it does not in any way damage the
steering system.

EthanolThe manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 10% ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 10% limit and/or of receiving fuel
with abnormal properties. It should also be
noted that an increase in fuel consumption
should be expected when using ethanol-
blended fuels, due to the lower energy content
of ethanol. Problems that result from using
methanol/gasoline or E-85 ethanol blends are
not the responsibility of the manufacturer. While
MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
CAUTION!
Use of fuel with Ethanol content higher than
10% may result in engine malfunction, start-
ing and operating difficulties, and materials
degradation. These adverse effects could
result in permanent damage to your vehicle.
Clean Air GasolineMany gasolines are now being blended to con-
tribute 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 “reformulated gasoline.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
MMT In GasolineMMT is a manganese containing metallic additive
that is blended into some gasoline to increase
octane. Gasoline blended with MMT provides no
performance advantage beyond gasoline of the
same octane number without MMT. Gasoline
blended with MMT reduces spark plug life and
reduces emission system performance in some
vehicles. The manufacturer recommends that
gasoline without MMT be used in your vehicle.
The MMT content of gasoline may not be indi-
cated on the gasoline pump; therefore, you
should ask your gasoline retailer whether or not
his/her gasoline contains MMT.
Materials Added To FuelBesides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-
ents. These can harm fuel system gasket and
diaphragm materials.

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 sys-
tem. 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
removed or the tank is being filled.
(Continued)
WARNING!(Continued)
•Never add fuel when the engine is running.
This is in violation of most state and fed-
eral fire regulations and may cause the
malfunction indicator light 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.
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 indica-
tion that the cap is properly tightened.
•If the gas cap is not tighten properly, the MIL
will come on. Be sure the gas cap is tight-
ened every time the vehicle is refueled.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use
the fuel filler door emergency release.
1. Open the liftgate.
2. Push down on the inboard edge of the left
storage bin, this will pop up the outboard edge.
3. Grab popped up outboard edge with other
hand to disengage snaps.
4. Remove the storage bin.
5. Pull the release cable.
