388 SERVICING AND MAINTENANCE
SCHEDULED SERVICING— DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
Required Maintenance Intervals
Refer to the maintenance plan on the following
pages for the required maintenance intervals.
More frequent maintenance may be needed in
severe conditions, such as dusty areas and very
short trip driving. In some extreme conditions,
additional maintenance not specified in the
maintenance schedule may be required.
At Each Stop For Fuel
Check the engine oil level at least 30 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.
Once A Month
Inspect the batteries, and clean and tighten the

terminals as required.
Check the fluid levels of the coolant reservoir,

brake master cylinder, and automatic transmis-
sion, and add as needed.
At Each Oil Change
Change the engine oil filter.

Inspect the exhaust system.

Check tire pressure and look for unusual wear

or damage. Rotate tires at the first sign of irreg-
ular wear, even if it occurs before the oil indi-
cator system turns on.
Inspect engine air cleaner filter. Replace the

engine air cleaner filter, if necessary.
Inspect the CV/Universal joints.

Check the coolant level, hoses, and clamps.

Inspect front end, and lubricate — If equipped

with serviceable fittings.
Inspect and replace the Evaporative System

Fresh Air Filter as necessary, replacement may
be more frequent if vehicle is operated in
extreme dusty conditions.
Inspection and service should also be performed
anytime a malfunction is observed or suspected.
Retain all receipts.
NOTE:
Using white lithium grease, lubricate the door
hinge pivot joints twice a year to prevent
premature wear.
