When the ignition switch is in the ON (II) position, and the remaining engine oil life is 1 % to 5 %, the message "SERVICE" (A) is displayed along with engine oil life and the same maintenance item code(s).
When the ignition switch is in the ON (II) position, and the remaining engine oil life is 0 %, the engine oil life indicator (A) blinks. Pressing the Select/Reset knob cancels the display, but the maintenance minder indicator stays on.
If the indicated maintenance is not done, the engine oil life indicator shows a negative mileage, for example "-10," on the display. If The negative mileage is between 0 and -9, the indicator is displayed for only a few seconds when the ignition switch is turned to the ON (II) position. The negative mileage (A) remains displayed after the vehicle is driven more than 10 miles (for USA models) or 10 km (for Canada models) after 0 % oil life is reached life is reached, and the display cannot be cancelled. This means the indicated maintenance item(s) should have been done more than 10 miles (or 10 km) ago.

Note. The vehicle must be stopped to reset the display. If a required service is done and the display is not reset, or if the maintenance display is reset without doing the service, the system will not show the proper maintenance timing. This can lead to serious mechanical problems because there will be no accurate record of when the required maintenance is needed. The engine oil life and the maintenance items can be reset independently only with the HDS.

MAINTENANCE MAIN ITEMS

Number	Maintenance Sub Items
1	Rotate tires, and check tire inflation and condition. Follow the pattern shown in the Owner's Manual.
2	Replace air cleaner element (see COMPONENT LOCATION INDEX ). If the vehicle is regularly driven in dusty conditions, replace the element every 15,000 miles (24,000 km).
	Replace dust and pollen filter (see RECIRCULATION CONTROL MOTOR REPLACEMENT ). If the vehicle is driven in areas that have high concentrations of dust, pollen, or soot in the air, replace every 15,000 miles (24,000 km). Replace the filter whenever airflow from the heating and air conditioning system is less than normal.
	Inspect drive belt (see DRIVE BELT INSPECTION ). Look for cracks and damage, then check the position of the drive belt auto-tensioner indicator.
3	Replace automatic transmission fluid (see ATF REPLACEMENT ) and transfer (see TRANSFER ASSEMBLY FLUID REPLACEMENT ) fluid. Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission and transfer fluid temperatures. This requires transmission fluid changes more frequently than recommended by the Maintenance Minder. If the vehicle is regularly driven in these conditions, change the transmission and transfer fluid at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km). Automatic transmission fluid capacity 3.3 L (3.5 US qt), use Acura automatic transmission fluid (ATF-Z1). Transfer fluid capacity: 0.43 L (0.45 US qt), use Hypoid Gear Oil GL4 or GL5.
4	Replace spark plugs (see SPARK PLUG INSPECTION ). Use SILKR8A-S (NGK)
4	Inspect the valve clearance (cold) (see VALVE CLEARANCE ADJUSTMENT ). Intake: 0.21-0.25 mm (0.008-0.010 in.), Exhaust: 0.28-0.32 mm (0.011-0.013 in.).
5	Replace engine coolant (see COOLANT CHECK ). Capacity (including the reservoir): 6.5 L (1.72 US gal), use Acura Long Life Antifreeze/Coolant Type 2.
6	Replace rear differential fluid (see REAR DIFFERENTIAL FLUID INSPECTION AND REPLACEMENT ). Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanicals (shear) stress to fluid. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If the vehicle is regularly driven under these conditions, change the differential fluid at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km). Capacity: 2.53 L (2.67 US qt), use Acura automatic transmission fluid (ATF-21)
