Operation
The seat-belt and ignition switch warning system is fitted only to cars for the USA and Canadian markets, and 1989 models for Japan.

The warning system reminds the driver that he has not fastened his seat belt, or that he has left the key in the ignition switch when leaving the car.

The system includes warning relay 82 which has a buzzer. When the ignition switch is in the drive position, the relay is supplied (+54) from fuse 12, via red 29-pole connector 152B.

Seat-belt warning
The warning relay is supplied (+54) from fuse 5, via red 29-pole connector 152B and seat-belt warning lamp 72.

Driver's seat-belt switch 70 connects terminal GF of the relay to earth. The warning lamp will then light up and the buzzer will sound. When the seat-belt buckle is inserted into the lock, the switch will open, the lamp will be extinguished and the buzzer will be Silenced.

Ignition switch warning
As long as the key remains in the ignition switch, the supply will be live from terminal S of the ignition switch to the warning relay.

If the key is in the ignition switch and the driver's door is opened, door switch 54 will close. Terminal 1 of the relay will then be earthed and the buzzer will sound.

Fault-tracing hints
The seat-belt and ignition switch warning system will be operative when the ignition switch is in the drive position.

1. Check fuses 5 and 12 and check that the supply to them is live.
2. Check seat-belt warning lamp 72 and check that the supply to relay 82 is live.
3. Check the door switches, connectors, cable harnesses and earth connections.
