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 accu-
racy 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, add as required.
Once a Month
•Check the tire pressure and look for unusual wear or
damage.
•Inspect the battery, clean and tighten the terminals as
required.
•Check the fluid levels of engine coolant/anti-freeze
deaeration bottle, brake master cylinder, and transmis-
sion, and add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect brake hoses.
•Check the engine coolant/anti-freeze level, hoses, and
clamps.
•Inspect engine accessory drive belts. Replace as neces-
sary.
•Inspect for the presence of water in the fuel filter/
water separator unit.
