Jeep Cherokee (XJ): Maintenance schedules

SERVICE PROCEDURES

DESCRIPTION

Service and maintenance procedures for components and systems listed in Schedule "A" or "B" can be found by using the Group Tab Locator index at the front of this manual. If it is not clear which group contains the information needed, refer to the index at the back of this manual.

There are two maintenance schedules that show proper service based on the conditions that the vehicle is subjected to.

Schedule "A", lists scheduled maintenance to be performed when the vehicle is used for general transportation.

Schedule "B", lists maintenance intervals for vehicles that are operated under the conditions listed at the beginning of that schedule section.

Use the schedule that best describes the driving conditions.

Where time and mileage are listed, follow the interval that occurs first.

UNSCHEDULED INSPECTION

At Each Stop For Fuel

•  Check engine oil level, add as required.
•  Check windshield washer solvent and add if required.

Once A Month

•  Check tire pressure and look for unusual wear or damage.
•  Inspect battery and clean and tighten terminals as required. Check electrolyte level and add water as needed.
•  Check fluid levels of coolant reservoir, power steering, brake master cylinder, and transmission and add as needed.
•  Check all lights and all other electrical items for correct operation.

At Each Oil Change

•  Inspect exhaust system.
•  Inspect brake hoses.
•  Rotate the tires at each oil change interval shown on Schedule "A" (7,500 miles) or every other interval shown on Schedule "B" (6,000 miles).
•  Check coolant level, hoses, and clamps.
•  After completion of off-road operation, the underside of the vehicle should be thoroughly inspected. Examine threaded fasteners for looseness.

EMISSION CONTROL SYSTEM MAINTENANCE

The scheduled emission maintenance listed in bold type on the Maintenance Schedules, must be done at the mileage specified to assure the continued proper functioning of the emission control system. These, and all other maintenance services included in this manual, should be done to provide the best vehicle performance and reliability. More frequent maintenance may be needed for vehicles in severe operating conditions such as dusty areas and very short trip driving.
