LIGHTING SYSTEM T Symptom: Daytime running lights (DRL) do not illuminate. (Turn signals function normally.) DRL operate with engine running and following switches are off: Headlight switch Turn signal switch (Selected turn signal light flashes, other light remains illumi- nated) Hazard warning switch Parking brake switch (Parking brake released) Step 1 1. Position the vehicle on a flat surface and block the wheels to prevent vehicle movement. 2. Turn the ignition switch to ON. 3. Measure the voltage at the following terminal wires of the DRL control unit. 4. If correct, replace the DRL control unit. B+: Battery positive voltage Step 2 1. Disconnect the parking brake switch connector. 2. Check for continuity between the terminal of the switch and a body ground.

Before installation of the steering wheel reset the clock spring connector as follows: (1) Set the front wheels straight ahead. (2) Turn the clock spring connector clockwise until it stops. (3) Return 2.75 turns. (4) Align the marks (counterclockwise) on the clock spring connector and the outer housing. 4. Install the steering wheel and the air bag module. Verify that the air bag system is operating normally by monitor- ing the air bag warning light. Gartner Banana

T AUDIO FEATURES 1. Antitheft System To deter audio unit theft, the system is designed to accept a code number that makes the audio unit inop- erable if it is removed from the vehicle and then reconnected without inputting the correct code number. 4 If the antitheft system is activated, the unit will not operate and a code will flash on the display until the correct code is entered. 2. Headrest Speaker Headrest speakers are available. 3. Preset Memory A total of 18 broadcasting stations on AM, FM1, and FM2 bands can be quickly and easily set. 4. Automatic Memory By using the automatic memory function, which is independent from the preset memory, station selec- tions can be easily made in an area where the broadcasting station frequencies are not known. 5. Clock The clock display is incorporated within the audio display. 6. Metal Tape Automatic Detection The tape player automatically detects the use of metal tape and makes internal adjustments for metal tape playback. The word "METAL" is shown on the display. 7. Display Lights The unit's display lights can be switched on or off as desired. 8. Bodysonic System In order for sufficient bass reproduction to be possible in a car audio system, a large-diameter woofer must be equipped. However, these woofers are space consuming. With the bodysonic system, the "bass ,, sensation" can still be felt, ever without a woofer. 9. Auto Level Controller (ALC) If the optimum bodysonic level is set when the car is stopped, the level will feel insufficient due to vehicle vibration when the car is running. The autolevel controller automatically adjusts the bodysonic level to . . the appropriate amount at any speed. 45UOTX-221 Gartner Banana
