Jeep Grand Cherokee Operating Information Manual page 430

specific vehicle maintenance service intervals
that are required to keep your vehicle operating
properly and safely.
The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your dealer-
ship know your vehicle best, and have access
to factory trained information, genuine MOPAR
parts, and specially designed electronic and
mechanical tools that can help prevent future
costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.
NOTE:
• Under no circumstances should oil
change intervals exceed 12,500 miles
(20 000 km) or 12 months, whichever
comes first.

• Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before the
oil indicator system turns on.
• 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.
• Inspect for the presence of water in the fuel
filter/water separator unit.
• Completely fill the AdBlue Fluid tank.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
