Maintenance Minder™ General Information
Maintenance Minder
The Maintenance Minder is an important feature of the information display. Based on engine and transmission operating conditions, and accumulated engine revolutions, the Civic's onboard computer (PCM) calculates the remaining engine oil and the transmission fluid life. The system also displays the remaining engine oil life along with the code(s) for other scheduled maintenance items needing service.

Service Information
1.
The remaining engine oil life (A) is shown as a percentage on the information display. To see the current engine oil life, turn the vehicle to the ON mode, then push and release the SEL/RESET knob repeatedly until the engine oil life appears on the information display.
2.
When the vehicle is in the ON mode, and the remaining engine oil life is 15 % or less, the remaining engine oil life (A) and other scheduled maintenance item(s) needing service are displayed. The maintenance minder indicator (B) also comes on. To cancel the display and the indicator, press the SEL/RESET knob.

3.
When the vehicle is in the ON mode, and the remaining engine oil life is 0 %, the engine oil life indicator (A) blinks. Pressing the SEL/RESET knob cancels the display, but the Maintenance Minder indicator stays on.
4.
If the indicated maintenance is not done, the engine oil life indicator shows a negative distance traveled (A), for example "-10" on the display. If the negative distance traveled is between 0 and -9, the indicator is displayed for only a few seconds when turning the vehicle to the ON mode. The negative distance traveled 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, and the display cannot be canceled.
This means the indicated maintenance item(s) should have been done more than 10 miles (or 10 km) ago.
Resetting the Maintenance Minder
NOTE:
The vehicle must be stopped to reset the Maintenance Minder.
If a required service is done and the Maintenance Minder is not reset, or if the Maintenance Minder 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.
You can reset all maintenance items by batch, or you can select and reset each maintenance item individually on the display.
The engine oil life and maintenance item(s) can be independently reset with the HDS.

1.
Turn the vehicle to the ON mode.

2.
Push the SEL/RESET knob repeatedly until the engine oil life is displayed.

3.
Press and hold the SEL/RESET knob for 10 seconds or more. The engine oil life and the maintenance item code(s) will blink to show it is in reset mode.

NOTE: If you are resetting the Maintenance Minder when the engine oil life is more than 15 %, make sure any maintenance item(s) requiring service are done before resetting the display.

4.
If you reset all the maintenance items shown on the display "A23 (for example)", press and hold the SEL/RESET knob for 5 seconds or more. If you reset each maintenance item individually, select an item (complete list of maintenance main item(s) and sub item(s)) you wish to reset by rotating the SEL/RESET knob, and press and hold the knob for 5 seconds or more.

5.
The maintenance item code(s) will disappear, and the engine oil life returns to "100 %."
Resetting Individual Maintenance Items by HDS
1.

2.
Turn the vehicle to the ON mode.

3.

5.
Select ADJUSTMENT in the GAUGES with the HDS.

6.
