Operation
The seat-belt and ignition key warning system is fitted on cars for the U.S.A., Canadian and Japanese markets only.
The warning system notifies 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 the 29-pole white connector 152A.
Seat-belt warning
The warning relay is supplied (+54) from fuse 5, via the 29-pole red connector 152B and seat-belt warning lamp 72.
Driver's seat-belt switch 70 earths terminal GF of the relay. 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 and the lamp will be extinguished.
Ignition-key warning
As long as the key remains in the ignition switch, the supply will be run from terminal S of the ignition switch to the warning relay.
If the key is in the ignition switch when any of the doors is opened, corresponding door switch 54 will close. Terminal 2 of the relay will then be
earthed and the buzzer will sound.

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