2015 JEEP GRAND CHEROKEE light

CAUTION!
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 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 regula-
tions 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.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated 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.

mark. The total capacity from the MIN mark to the MAX
mark is 1.7 qts (1.6L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE:It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.
Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Engine Oil Viscosity (SAE Grade)
CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.
Only use ACEA C3 SAE 5W-30 Synthetic Low Ash engine
oil meeting FCA US Material Standard MS-11106 or
Pennzoil Ultra Euro L full synthetic 5W-30 motor oil,5

CAUTION!
•Do not drain the fuel/water separator filters when
the engine is running.
•Diesel fuel will damage blacktop paving surfaces.
Drain the filters into an appropriate container.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in the
ON position, the “Water In Fuel Indicator Light” will
illuminate and an audible chime will be heard. At this
point you should stop the engine and drain the water
from the filter housing.

82 MAINTAINING YOUR VEHICLE

CAUTION!
If the “Water In Fuel Indicator Light” remains on, DO
NOT START the engine before you drain water from
the fuel filters to avoid engine damage.
If the “Water In Fuel Indicator Light” comes on and a
single chime are heard while you are driving, or with the
ignition in the ON position, there may be a problem with
your water separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from fuel filter
assembly, the “Water In Fuel Indicator Light” will remain
illuminated for approximately 10 seconds. If the water
was drained while the engine was running, the “Water In
Fuel Indicator Light” may remain on for approximately
three minutes.NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact an authorized dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
Drain the fuel/water separator filters when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the filter drain valve (located on the
bottom of the filter housing) counterclockwise to drain
fuel/water, then turn the ignition switch to the ON
position, and allow any accumulated water to drain.
Leave the drain valve open until all water and contami-
nants have been removed. When clean fuel is visible,
close the drain valve by turning it clockwise, and turn the
ignition switch to OFF.

Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned in front of the radiator
and the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air
rapidly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through
another hose to the intake manifold of the engine. This
cooling process enables more efficient burning of fuel
resulting in fewer emissions.
To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and
radiator clean and free of debris. Periodically check the
hoses leading to and from the charge air cooler for cracks
or loose clamps resulting in loss of pressure and reduced
engine performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immedi-
ately if the “Brake System Warning Light” indicates
system failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.

Engine Oil Filter Replacement
Residual oil in the housing may spill from the housing
when the new filter is installed if the residual oil is not
either removed from the housing or enough time has not
elapsed to allow the oil to drain back into the engine.
When servicing the oil filter on this engine, carefully
remove the filter and use a suction gun to remove any
residual oil left in the housing or wait about 30 minutes
for the oil to drain back into the engine.
Once A Month Or Before A Long Trip:
•Check engine oil level
•Check windshield washer fluid level
•Check the tire inflation pressures and look for unusual
wear or damage•Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and transmission as
needed
•Check function of all interior and exterior lights
