For 1990-2009 cars only

The stereo cassette AM/FM radio is standard and the compact disc player is offered as optional equipment. All audio systems use four speakers: two speakers mounted in the front doors and two speakers mounted behind the rear seats.

Audio Security System (Non European Only)

The audio security system is activated whenever the audio system circuit is disconnected from the battery. A 4-digit security code must be entered for the audio system to resume functioning. The security code is stamped on a card located in the vehicle, usually in the glove box. The following security code entering procedure must be used to deactivate the audio security system:

  1. With the ignition switch in the ACC position. Turn the radio ON. At this time, CODE will be shown on the radio display, accompanied by chime sounds.
  2. Enter the 4-digit security number using the radio preset buttons 1 through 6, or 1 through 8, if equipped.
  3. After all four digits are entered, the digits will blink three times, and the radio will be functional.

Wrong Code

If the wrong code is entered, ERR will briefly appear on the display. After this, CODE will appear, and the code entering procedure can be performed once again. If the correct code is not entered within 10 minutes, the radio should be disconnected from the battery to reset the audio system. After connecting the battery, repeat the code entering procedure.

Roof Antenna

Roof antenna is located on the roof and is designed to separate the antenna pole from the antenna base. The antenna pole should be removed to prevent paint damage before washing the vehicle. The roof antenna cannot be adjusted.

Front and Rear Speakers

All audio systems use four speakers: two speakers mounted in the front doors and two speakers mounted in the rear deck lid sill plate, on the notchback. On the hatchback, the rear speakers are mounted in the luggage compartment wheelhouse trim panel. A coaxial 2-way rear speaker is offered as an option.

Tape Player and Cassette Care

The head and the capstan are the two parts of the tape player that should be cleaned. This service should be performed every 100 hours of cassette operation.

In order to clean the head and the capstan, use a cotton swab dipped in rubbing alcohol.

A cassette cleaning kit may also be used to clean the head and the capstan. Follow the cleaning kit instructions to clean the tape player.

Do not touch the tape head with magnetized tools. If the head becomes magnetized, it will degrade cassettes played in the player. No service is performed on the cassettes. The cassette manufacturer handles warranties of the cassettes. Store cassettes away from extreme heat and direct sunlight.

Compact Disc Care

Handle discs carefully. Store the discs in protective cases away from the sun, heat, and dust. If the surface is soiled, dampen a clean, soft cloth in a solution of mild neutral detergent and wipe the disc clean.

Setting the Area Code (Non European Only)

When you turn the 'Power Button,' AF' will be displayed. The consumer must select the area code as per map in the owner's manual. If you select the wrong area code, you must re-install the audio connector, (or can be possible to remove the audio fuse). Refer to the audio owners manual for the area code.
