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 door
    • To be driven on reasonable road surfaces and within the legal operating limits

Explanation of Scheduled Maintenance Services

The services listed in the maintenance schedule are further explained below. When the following maintenance services are performed, make sure all the parts are replaced and all the necessary repairs are done before driving the vehicle. Always use the proper fluid and lubricants.

Drive Belt Inspection

When a separate belt drives the power steering pump, the air conditioning compressor and the generator, inspect it for cracks, fraying, wear, and proper tension. Adjust or replace the belt as needed.

Engine Oil and Oil Filter Change

The International Lubricant Standardization and Approval Committee (ILSAC) and American Petroleum Institute 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, thickness, 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. Using oils of any viscosity other than those viscosities recommended could result in engine damage.

Cooling System Service

Drain, flush and refill the system with new coolant. Refer to Fluid and Lubricant Recommendations .

Fuel Micro-Filter Replacement - European Emissions

Replace the engine fuel filter every 45,000 km (27,000 mi).

Fuel Micro-Filter Replacement - Non-European Emissions

Replace the engine fuel filter every 45,000 km (27,000 mi).

Air Cleaner Element Replacement - European Emissions

    • Replace the air cleaner element every 45,000 km (27,000 mi).
    • Replace the air cleaner more often under dusty conditions.

Air Cleaner Element Replacement - Non European Emissions

    • Replace the air cleaner element every 45,000 km (27,000 mi).
    • Replace the air cleaner more often under dusty conditions.

Throttle Body Mounting Bolt Torque

Inspect the torque of the throttle body mounting bolts.

Tighten
Tighten the throttle body mounting bolts to 10 N·m (89 lb in) if necessary.

Spark Plug Replacement

Refer to Maintenance Items .

Replace the spark plugs with the same type.

Spark Plug Wire Replacement

Clean the wires and inspect them for burns, cracks, or other damage. Inspect the wire boot fit at the direct ignition system (DIS) module and at the spark plugs. Replace the wires as needed.

Brake System Service - European Emission

Inspect the disc brake pads every 15 000 km (9,000 mi), or 12 months. Inspect the pad thickness carefully. If the pads are not expected to last another 15 000 km (9,000 mi), replace the pad. Inspect the breather hole in the brake fluid reservoir cap to be sure it is free from dirt and the passage is open.

Brake System Service - Non European Emissions

Inspect the disc brake pads every 10 000 km (6,000 mi), or 6 months. Inspect the pad thickness carefully. If the pads are not expected to last another 10 000 km (6,000 mi), replace the pad. Inspect the breather hole in the brake fluid reservoir cap to be sure it is free from dirt and the passage is open.

Transaxle Service

The manual transaxle fluid does not require changing. For automatic transaxles, refer to Transmission Fluid Level Inspection .
