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 and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of coolant bottle, brake master
cylinder, and transmission and add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change

•Lubricate Drivetrain/Steering/Suspension Grease Fit-
tings (if equipped)

front suspension components.
•Check the automatic transmission fluid level.
