Maintenance Main Items
If the message ‘‘SERVICE’’ does not appear more than 12 months after the display is reset, change the engine oil every
year.
NOTE:


 Replace the brake fluid every 3 years independent of the maintenance messages in the information display.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2 or 3, only if they are noisy.

















A Replace engine oil (see page 8-10).
Engine oil capacity without oil filter:
K20Z2: 4.0 L (4.2 US qt)
K20Z3: 4.2 L (4.4 US qt)
B Replace engine oil and oil filter (see page 8-11). Engine oil capacity with oil filter:
K20Z2: 4.2 L (4.4 US qt)
K20Z3: 4.4 L (4.6 US qt)
Check front and rear brakes (see page 19-3). Check pad and disc for wear (thickness), damage, and cracks.
Check calipers for damage, leaks, and tightness of mounting bolts.
Check parking brake adjustment (see page 19-7). Check the number of clicks (8 to 10) when the parking brake lever is pulled with 196 N (20 kgf,
44 lbf) of force.
Inspect tie-rod ends, steering gearbox, and gearbox boots (see page 17-5). Check steering linkage.
Check boots for damage and leaking grease.
Check fluid lines for damage and leaks.
Inspect suspension components (see page 18-3). Check bolts for tightness.
Check condition of ball joint boots for deterioration and damage.
Inspect driveshaft boots (see page 16-4). Check boots for cracks and boot bands for tightness.
Inspect brake hoses and lines including VSA lines (see page 19-37). Check the master cylinder and VSA modulator-control unit for damage or leakage.
Inspect all fluid levels and condition of fluids. Engine coolant (see page 10-7)
Automatic transmission fluid (ATF-Z1) (see page 14-231)
Manual transmission fluid (MTF)
5M/T (see page 13-5), 6M/T (see page 13-82)
Clutch fluid (see page 12-7)
Brake fluid (see page 19-9)
Windshield washer fluid (see page 22-234)
Inspect exhaust system: K20Z2 (see page 9-13), K20Z3 (see page 9-14)
Check catalytic converter heat shields, exhaust pipes, and muffler for damage, leaks, and tightness.
Inspect fuel lines (see page 11-326) and connections (see page 11-328). Check for loose connections, cra cks, and deterioration; retighten loose connections and replace
damaged parts.
NOTE: According to state and federal regulations, failure to do the maintenance items marked with an asterisk ( ) will
not void the client’s emissions warranties. However, Acura recommends that all maintenance services be done at the
recommended interval, to ensure long-term reliability.

1. Remove the center console panel (see page 20-92).
2. Release the parking brake lever fully.
3. Loosen the parking brake adjusting nut (A).
4. Raise the rear of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
5. Remove the rear wheels. 6. Make sure the lever (A) on the rear brake caliper
contacts the stop pin (B).
NOTE: The lever will only contact the stop pin when
the parking brake adjusting nut is loosened.
7. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear
wheels.
8. Pull the parking brake lever 1 click.
9. Tighten the parking brake adjusting nut until the parking brakes drag slightly when the rear wheels
are turned.
10. Release the parking brake lever fully, and check that the parking brakes do not drag when the rear
wheels are turned. Readjust if necessary.
11. Make sure the parking brake lever is within the specified number of clicks (8 to 10 clicks).
12. Install the center console panel (see page 20-92).

14. Rotate the caliper piston (A) clockwise into the
cylinder, then align the cutout (B) in the piston with
the tab (C) on the inner pad by turning the piston
back. Lubricate the boot with rubber grease to
avoid twisting the piston boot. If the piston boot is
twisted, back it out so it is positioned properly.
NOTE: Be careful when moving the piston back in
the caliper; brake fluid might overflow from the
master cylinder’s reservoir. If brake fluid gets on
any painted surface, wash it off immediately with
water.
15. Install the caliper. Install the flange bolts (D), and tighten it to the specified torque while holding the
respective caliper pin with a wrench being careful
not to damage the pin boots.
16. Install the brake hose mounting bolt (E).
17. Clean the mating surfaces between the brake disc and the inside of the wheel, then install the rear
wheels. 18. Press the brake pedal several times to make sure
the brakes work.
NOTE: Engagement may require a greater pedal
stroke immediately after the brake pads have been
replaced as a set. Several applications of the brake
pedal will restore the normal pedal stroke.
19. Add brake fluid as needed.
20. After installation, check for leaks at hose and line joints or connections, and retighten if necessary.
Test-drive the vehicle, then recheck for leaks
(see page 19-37).

The electronic brake distribution (EBD) feature helps control vehicle braking by adjusting the rear brake force in
accordance with the rear wheel load before the ABS operates. Based on the wheel speed sensor signals, the control
unit uses the modulator to control the rear brakes individually. When the rear wheel speed is less than the front wheel
speed, the ABS modulator-control unit retains the current rear brake fluid pressure by closing the inlet valve in the
modulator. As the rear wheel speed increases, and approaches the front wheel speed, the ABS modulator-control unit
increases the rear brake fluid pressure by momentarily opening the inlet valve. This whole process is repeated very
rapidly. While this is happening, kickback may be felt at the brake pedal.

The electronic brake distribution (EBD) feature helps control vehicle braking by adjusting the rear brake force in
accordance with the rear wheel load before the ABS operates. Based on the wheel speed sensor signals, the control
unit uses the modulator to control the rear brakes individually. When the rear wheel speed is less than the front wheel
speed, the VSA modulator-control unit retains the current rear brake fluid pressure by closing the inlet valve in the
modulator. As the rear wheel speed increases, and approaches the front wheel speed, the VSA modulator-control unit
increases the rear brake fluid pressure by momentarily opening the inlet valve. This whole process is repeated very
rapidly. While this is happening, kickback may be felt at the brake pedal.
When a drive wheel loses traction on a slippery road surface and starts to spin, the VSA modulator-control unit applies
brake pressure to the spinning wheel, and sends an engine torque control request to the ECM/PCM to slow the
spinning wheel and keep traction.
