vice).

NOTE: Most vehicles are operated under the condi-
tions listed for Schedule B .
Second is Schedule "A". It is for vehicles that are

Schedule B .
Use the schedule that best describes your driving
conditions. Where time and mileage are listed, follow
the interval that occurs first.
CAUTION: Failure to perform the required mainte-
nance items may result in damage to the vehicle.
At Each Stop for Fuel
• Check the engine oil level about 15 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.
• Check the windshield washer solvent and add if
required.
• Drain water from the fuel filter.
