2015 JEEP GRAND CHEROKEE fuel pressure

Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the “SAFE” range. Adding one quart of oil
when the reading is at the bottom of the “SAFE” range
will result in an oil level at the top of the “SAFE” range
on these engines.
NOTE:Fill engine oil one quart at a time.
CAUTION!
•Overfilling or underfilling will cause oil aeration
or loss of oil pressure. This could damage your
engine.
•
Operating the engine with the oil levels below the
safe zone, or operating with oil levels that exceed the
top of the safe zone may cause engine damage.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to “Maintenance Schedule” for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 6,000 miles (10,000 km) or six months,
whichever occurs first.
532 MAINTAINING YOUR VEHICLE

Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Driver Informa-
tion Display (DID)” in “Understanding Your Instrument
Panel” for further information.
At Each Stop For Fuel
•Check the engine oil level. Refer to “Maintenance
Procedures/Engine Oil” in “Maintaining Your Ve-
hicle” for further information.
•Check the windshield washer solvent and add if
required.
Once A Month

damage.•Inspect the battery, and clean and tighten the terminals
as required.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering, and add as
needed.
•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
