Jeep XJ. Manual - part 4

API QUALITY CLASSIFICATION

This symbol (Fig. 2) on the front of an oil container

means that the oil has been certified by the Ameri-
can Petroleum Institute (API) to meet all the lubri-
cation requirements specified by DailmlerChrysler
Corporation.

Refer to Group 9, Engine for gasoline engine oil

specification.

GEAR LUBRICANTS

SAE ratings also apply to multiple grade gear

lubricants. In addition, API classification defines the
lubricants usage.

LUBRICANTS AND GREASES

Lubricating grease is rated for quality and usage

by the NLGI. All approved products have the NLGI
symbol (Fig. 3) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
“G”. Chassis lubricant is identified by the latter “L”.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.

SERVICE PROCEDURES

DESCRIPTION

Service and maintenance procedures for compo-

nents 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 vehi-
cle is subjected to.

Schedule “A”, lists scheduled maintenance to be

performed when the vehicle is used for general trans-
portation.

Schedule “B”, lists maintenance intervals for vehi-

cles 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

the

vehicle

should

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 mainte-
nance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
