Explanation of Scheduled Services USA and Canada

Normal Vehicle Use

The maintenance instructions contained in the maintenance schedule are based on the assumption that the vehicle will be used for the following reasons:

    • To carry passengers and cargo within the limitation indicated on the tire placard located on the edge of the driver's door.
    • To be driven on reasonable road surfaces and within legal operating limits.

Explanation of Scheduled Maintenance Services

The services listed in the maintenance schedule are further explained below. Always use the proper fluids, lubricants, and service replacement parts for the vehicle.

Drive Belt Inspection

Inspect the drive belts for cracks, fraying, wear and proper tension every 12 000 km (7,500 mi) or every 6 months, whichever comes first. Adjust or replace the belt as needed.

Engine Oil and Oil Filter Change

If the vehicle is operated under any of the following conditions, change the engine oil and the oil filter every 6 000 km (3,750 mi) or every 3 months, whichever comes first.

    • Short distance driving
    • Extensive idling
    • Driving on dirty roads

If none of the above conditions apply, change the engine oil and the oil filter every 12 000 km (7,500 mi) or every 6 months, whichever comes first.

API Classifications of Engine Oil

The International Lubricant Standardization and Approval Committee (ILSAC) and American Petroleum Institute (API) classifies engine oils according to their performance quality. Always use oil rated API-SL (ILSAC GF-III) or better.

Engine Oil Viscosity

Notice: Using engine oils of any viscosity other than those viscosities recommended could result in engine damage.

Engine oil viscosity has an effect on fuel economy and cold weather operation. Lower viscosity engine oils can provide better fuel economy and cold weather performance; however, higher temperature weather conditions require higher viscosity engine oils for satisfactory lubrication.

If the pads are not expected to last to the next scheduled maintenance service, replace the pads. Inspect the breather hole in the brake fluid reservoir cap. Ensure the breather hole is free from dirt and the passage is open.

More frequent service is necessary if the vehicle is operated under any of the following conditions:

    • Short distance driving
    • Extensive idling

Inspect the manual transaxle fluid every 48 000 km (30,000 mi). The manual transaxle fluid does not require changing.

Inspect the automatic transaxle fluid every 24 000 km (15,000 mi). If the vehicle is operated under any of the following conditions, change the automatic transaxle fluid every 60 000 km (37,500 mi):

    • In heavy city traffic where the outside temperature regularly exceeds 32°C (90°F)
    • In hilly or mountainous terrain
    • In taxi, police, or delivery service

Tire and Wheel Inspection and Rotation

Measure and adjust the tire inflation pressure every 12 000 km (7,500 mi) or every 6 months, whichever comes first.

Inspect the tires for abnormal wear or damage. To equalize wear and obtain maximum tire life, rotate the tires every 12 000 km (7,500 mi). If irregular or premature wear exists, measure the wheel alignment and inspect for damaged wheels. While the tires and wheels are removed, inspect the brakes. Refer to Owner Checks and Services .
