NOTE: Keep all foreign particles out of the transmission. 1. Park the vehicle on the level ground.
2. Warm up the engine to normal operating temperature (the radiator fan comes on), and turn
the engine off.
3. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
4. Reinstall the drain plug with a new sealing washer (B).
5. Refill the transmission with ATF into the dipstick hole to bring the fluid level between the upper
mark and the lower mark of the dipstick. Always
use Acura ATF-Z1 automatic transmission fluid
(ATF). Using a non-Acura ATF can affect shift
quality.
6. Check that the ATF level is between the upper mark
and the lower mark of the dipstick.
7. Insert the dipstick back into the transmission with the letters ‘‘ATF’’ pointing toward the front of the
vehicle. 8. If the maintenance minder required to replace the
ATF, reset the maintenance minder (see page 3-4),
and this procedure is complete. If the maintenance
minder did not require you to replace the ATF, go
to step 9.
9. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
10. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
11. Select BODY ELECTRICAL with the HDS.
12. Select ADJUSTMENT in the GAUGES MENU with the HDS.
13. Select RESET in the MAINTENANCE MINDER MENU with the HDS.
14. Select RESETTING THE ATF with the HDS.
NOTE: If you changed the engine oil at the same
time with the ATF, select RESETTING THE ENGINE
OIL LIFE AND ATF with the HDS instead.
Replace.

System Description (cont’d)
Certain inputs happen so quickly that the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List.
This should give the HDS time to update the signal on the Data List.
Because the HDS software is updated to support the release for newer vehicles it is not uncommon to see system function tests that are not
supported.
Make sure that the most current software is loaded.

appear inoperative.
GB (Gigabyte) A unit of memory or disk storage equal to billion bytes (1000 million bytes).
HDD Abbreviation for hard disc drive. They are sensitive to heat and it is not
recommended that they be used in the PC card slot for playing audio files.
Hertz (Hz) The unit of frequency equal to one cycle per second (cps). One kilohertz (kHz)
equals 1,000 cps; one megahertz (MHz) equals 1 million cps.
Integrated amplifier A component that combines a pre amp and a power amp into a single unit. A
receiver combines an integrated amp and a tuner into a single unit.
Jewel case The hard plastic case that contains a compact disc or DVD. Always use a jewel
case to prevent scratches on the underside of a CD or DVD.
LCD (Liquid Crystal Display) A type of digital display that changes reflectance or transmittance when an electrical field is applied to it.
Memory Circuitry or devices that hold information in electrical or magnetic form, such
as the AM/FM radio presets.
MB (Megabyte) One million bytes. Written as 1 MB. Megabytes are used as a measure of digital
storage space. For example, a CD can hold 650 MB.
Mic An abbreviation for microphone. For vehicles with navigation, the microphone
accepts navigation voice commands to control audio and navigation functions.
MP3 music files MP3 is an audio coding format. MP3 is a popular audio compression format on
the Internet and computers. CDs and PC Cards with these files can be played on
some vehicle’s audio system.
Mute When the navigation gives guidance, the front speakers are muted (no music).
When you use the voice control system, all of the speakers are muted.
Noise Unwanted random sounds like buzzing, hiss, pops, static, whine, etc.
PC card The slot used for playing MP3 and WMA music files. The PC Card is usually a
combination of a small flash card in a PCMCIA adaptor that slides into the slot.
The ATA, SD, and compact flash types of cards have been tested up to 1 GB.
PCMCIA A computer standard for the slot that the PC card slides into. Another term for
the PC card slot.
Processor The part of an audio device that performs tasks/calculations. In the audio unit
the processor handles muting to allow the navi to speak its voice commands,
and the decoding/playback of the sound files etc.
Radio A head unit that combines a tuner, a preamplifier, and often a power-amplifier.
Route guidance (RG) Spoken voice used for turn-by-turn navigation from the audio speakers.
SCF (Cold Start Fix) screens These screens are displayed if the system requires a GPS initialization. The vehicle should be moved outside into an open area away from buildings/power
lines.
Stereo A recording of at least two channels where you can hear sound or music from
the left or right side.
SD (Secure Digital) card This compact type of memory card allows for fast data transfer and has built-in security functions. SD cards have a small write-protection switch on the side.
Shield A metallic foil or braided wire layer surr ounding conductors which are
designed to prevent electrostatic or electromagnetic interference (noise) from
external sources such as buzzing, or popping sounds heard on the speakers.
Speaker (Loudspeaker) A device that converts electrical energy into acoustical energy (sound).
Speed-sensitive volume
compensation (SVC) The SVC increases the audio volume to compensate for increased interior noise
when the vehicle drivers at freeway speeds.
Subwoofer A loudspeaker made to reproduce the lowest audio frequencies, about 25 Hz to
125 Hz.
