2015 JEEP GRAND CHEROKEE check oil

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 indica-
tors.
•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 recommended viscosity and quality grades are
shown under “Fluids, Lubricants and Genuine Parts”,
under “Maintaining Your Vehicle” in this manual. NON-
DETERGENT OR STRAIGHT MINERAL OILS MUST
NEVER BE USED.
10 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

4. If you wish to stop the cranking of the engine prior to
the engine starting, push the button again.
5. Check that the oil pressure warning light has turned
off.
6. 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 make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the 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 transmission gear selector. Do not leave the
key fob in or near the vehicle (or in a location
accessible to children), and do not leave the igni-
tion (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.
40 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.
NOTE:If the coolant temperature is too high the A/C
will automatically turn off.
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.
44 STARTING AND OPERATING

Engine Oil
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer recom-
mends engine oils that meet the requirements of FCA US
Material Standard MS-11106, and that are approved to
ACEA C3.
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check
the oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tem-
perature, then wait for five minutes after engine shut-
down to check the oil.
1 — MAX Mark
2 — MIN Mark
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”
76 MAINTAINING YOUR VEHICLE

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

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
