Application Lubricant or Fluid
3-2Lubricants and Fluids
API CERTIFICATION SEAL
For details of the lubrication points and the type of lubricants to be applied, refer to the illustrated index and the various work procedures (such
as Assembly/Reassembly, Replacement, Overhaul, Installation, etc.) contained in each section.


A Engine Acura Motor Oil:
K20Z2: P/N CA66808 (5W-20)
K20Z3: P/N CA66807 (5W-30)
Look for the API certification seal on the oil container. Make sure it says ‘‘For
Gasoline Engines.’’ SAE viscosity: See chart.
B Manual transmission Acura Manual Transmission Fluid (MTF): P/N 08798-9033C Always use Acura MTF. Using motor oil can cause stiffer shifting because it
does not contain the proper additives.
Automatic transmission Acura Automatic Transmission Fluid (ATF-Z1): P/N CA66704 Always use Acura ATF-Z1. Using a non-Acura ATF can affect shift quality.
C
D Brake system (including VSA lines)
Clutch system (manual transmission) Honda DOT 3 Brake Fluid: P/N 08798-9008
Always use Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can
cause corrosion and decrease the life of the system.

General Information
MAINTENANCE MINDER INDICATOR
INFORMATION DISPLAY
SEL/RESET BUTTON
The maintenance minder is an important feature of the information display. Based on engine and transmission
operating conditions, the Acura CSX’s onboard computer (ECM/PCM) calculates the remaining engine oil and the
automatic transmission fluid life. The system also displays the remaining engine oil life along with the code(s) for
other scheduled maintenance items needing service.

1. The remaining engine oil life (A) is shown as apercentage on the information display. To see the
current engine oil life, turn the ignition switch to
ON (II), then push and release the SEL/RESET
button repeatedly until the engine oil life displays.
2. When the ignition switch is ON (II), and the remaining engine oil life is 6 % to 15 %, the
remaining engine oil life (A) and other scheduled
maintenance item(s) needing service are displayed.
The maintenance minder indicator (B) also comes
on when the engine oil life is 15 % or less. To
cancel the display and the indicator, press SEL/
RESET button.
 Complete list of maintenance main items (C) (see page 3-7).
 Complete list of maintenance sub items (D) (see page 3-8). 3. When the ignition switch is ON (II), 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).
4. When the ignition switch is ON (II), and the remaining engine oil life is 0 %, the engine oil life
indicator (A) blinks. Pressing SEL/RESET button
cancels the display, but the maintenance minder
indicator stays on.
5. 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 ON (II). The negative mileage
remains displayed after the vehicle is driven more
than 10 km 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 km ago.

Resetting Maintenance Information Display Resetting Individual Maintenance Items
3-6Maintenance Minder
General Information (cont’d)
NOTE:
 The vehicle must be stopped to reset the display.
 If a required service is done and the display is not reset, or 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 item(s) can be only reset independently with the HDS.
1. Turn the ignition switch to ON (II).
2. Push and release the SEL/RESET button repeatedly until the engine oil life indicator is displayed.
3. Press and hold the SEL/RESET button for about 10 seconds. The engine oil life indicator and the
maintenance item code(s) will blink, then release
the button.
NOTE: If you are resetting the display when the
engine oil life is more than 15 %, make sure the
maintenance item(s) requiring service are done
before resetting the display.
4. Press and hold the SEL/RESET button for another 5 seconds. The maintenance item code(s) will
disappear, and the engine oil life will reset to ‘‘100’’. 1. Connect the Honda Diagnostic System (HDS) to the
data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module/powertrain control
module (ECM/PCM). If it doesn’t communicate,
troubleshoot the DLC circuit (see page 11-6).
4. Select GAUGES in the BODY ELECTRICAL with the HDS.
5. Select ADJUSTMENT in the GAUGES with the HDS.
6. Select SERVICE REMINDER in the ADJUSTMENT with the HDS.
7. Select RESET in the SERVICE REMINDER with the HDS.
8. Select the individual maintenance item you wish to reset.
