2014 JEEP GRAND CHEROKEE check engine light

WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Mon-
oxide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious in-
jury or death when inhaled.
• Keep Remote Keyless Entry (RKE) transmitters
away from children. Operation of the Remote Start
System, windows, door locks or other controls
could cause serious injury or death.
ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
• Warm up the engine before placing it under load.
•
Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent
engine lugging.
•
Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.
NOTE: Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. The recom-
mended viscosity and quality grades are shown under
“Fluids, Lubricants and Genuine Parts”, under “Maintain-
ing Your Vehicle” in this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 7

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Seat Belt Reminder LightWhen the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” in your Owner Manual on
the DVD for further information. 3. 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 seconds.
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.

4. High Beam IndicatorIndicates that headlights are on high beam.
5. Front Fog Light Indicator — If Equipped This indicator will illuminate when the front fog
lights are on.
6. Selectable EVIC Information
This area of the cluster will display selectable information
(such as compass, outside temperature etc.). For further
information, refer to “Electronic Vehicle Information Cen-
ter (EVIC) — If Equipped” in your Owner Manual on the
DVD.
7. Turn Signal Indicator
The arrows will flash with the exterior turn sig-
nals when the turn signal lever is operated. A tone
will chime, and an EVIC message will appear if either
turn signal is left on for more than 1 mile (1.6 km). NOTE:
If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
8. Speedometer
Indicates vehicle speed.
9. Selectable EVIC Information
This area of the cluster will display selectable informa-
tion (such as compass, outside temperature etc.). For
further information, refer to “Electronic Vehicle Informa-
tion Center (EVIC) — If Equipped” in your Owner
Manual on the DVD.
10. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in

the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to
ON/RUN, have the condition checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should be serviced
if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive
normally and will not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
11. Parking Brake Indicator
This light indicates the parking brake is engaged.

6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed,
the engine should start in all conditions and no type of
starting fluid should be used.
WARNING!
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
(Continued)
WARNING! (Continued)
•When leaving the vehicle, always remove the key
fob and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever. Do not leave the key fob in or
near the vehicle (or in a location accessible to
children), and do not leave the ignition of a vehicle
equipped with Keyless Enter-N-Go™ in the ACC
or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
38 STARTING AND OPERATING

NOTE:Under certain conditions the engine fan will run
after the engine is turned off. These conditions are under
high load and high temperature conditions.
Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission
overheating in high ambient temperature conditions,
take the following actions:
• City Driving — When stopped, shift the transmission
into NEUTRAL and increase engine idle speed.
• Highway Driving — Reduce your speed.
• Up Steep Hills — Select a lower transmission gear.
• Air Conditioning — Turn it off temporarily.
Do Not Operate The Engine With Low Oil
Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as
soon as possible. A chime will sound when the light
turns on.
NOTE: Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
42 STARTING AND OPERATING

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil
only when the level on the dipstick is below the “MIN”
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.
