MAINTENANCE SCHEDULE — DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
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 termi-
nals as required. •
Check the fluid levels of the coolant reservoir, brake
master cylinder, and automatic transmission (if
equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.
