Rear Fog Lights

Cars for certain markets are fitted with rear fog lights. Before the rear fog lights can be turned on, the ignition switch must be in the Drive position.

Current is supplied to lights switch 10 from the ignition switch. The rear fog light cannot be turned on unless the lights switch is in position 2 (head lamps on main or dipped beam).

Current is then supplied to the switch for rear fog light 161 via the switch for extra fog lights 88 and fuse 32. To enable the rear fog light to work on cars without extra fog lights, a jumper is connected via a 2-pin connector (H2-69).

When the rear fog light switch is depressed, rear fog light 33 lights up on the left-hand side on LHD cars and on the right-hand side on RHD cars. Indicator lamp 47n in the main instrument display panel also lights up.

At the same time as the switch is pressed, the lamp built into the switch button will be supplied with current and light up at full intensity.

The button remains in the depressed position and the rear fog light stays on until the button is released.

If the ignition is switched on with the button in the depressed position, the rear fog light will light up and must be switched off by releasing the button.

Rear fog light relay 246 is used to switch off the rear fog light automatically when the ignition is switched off or the lights switch turned to position 0 or 1.

Depressing spring-loaded switch 246 causes pin 3 (86) of the relay to be grounded. The relay operates and remains holding until lights switch 10 is turned to position 0 or 1 or the ignition is switched off.

To turn on the rear fog light again, switch 246 must be depressed afresh.

Trailers
The rear fog light on a trailer, if any, is supplied with current via connector 258 (H8-5).
