AUDIO SYSTEMS

Caution : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise noted.

DESCRIPTION AND OPERATION

STEREO CASSETTE AM/FM RADIO WITH CD CHANGER

The stereo digital logic cassette AM/FM radio with electronic tape ejection and the stereo digital logic cassette AM/FM radio with a CD changer located in the trunk are optional equipment.

AUDIO SECURITY SYSTEM (GENERAL ONLY)

The audio security system is activated whenever the audio system circuit is disconnected from the battery. A four-digit security code must be entered in order for the audio system to be functional once again. The security code is stamped on a card located in the vehicle (usually in the glove box).

Procedure

With the ignition switch in the ACC or ON position, turn the radio ON. At this time, "CODE" will be shown on the radio display along with chime sounds.
Enter the four-digit security number using the radio pre-set buttons 1 through 6.
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.

SETTING THE AREA CODE (GENERAL ONLY)

When you turn on the "Power" button, "AF" will be displayed. The customer must select the area code as per map in the Audio Owner's manual.

If you select wrong area code, you must re-install the audio connector. (Or can be possible to take off Audio fuse.)

The area code refer to the audio owner's manual.

FRONT AND REAR SPEAKERS

All audio systems use four speakers: two speakers mounted in the front doors and two speakers mounted in the rear.

TWEETER SPEAKERS

The tweeter speakers are mounted on the top side of the instrument panel.

ROOF ANTENNA

The two-piece roof antenna is standard equipment. The top half of the antenna can be unscrewed and removed if height clearance problems occur.

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. Mini discs (about 3 inches in diameter), will not eject and should not be used.
