Fog/Driving Lamp: Description and Operation

FOG LIGHT
The fog light switch becomes active only when the headlights are at the low-beam mode. Therefore, if the headlights are turned off, the fog lights will also be switched off. When the headlights are turned on during the next key cycle, the fog lights will be off regardless of the fog light switch position.




GENERAL DESCRIPTION CONCERNING FOG LIGHT




If the ETAS-ECU sends a fog light "on" request signal to the front-ECU after the low-beam headlights are on, the fog light relay is turned on, allowing the fog lights and the fog light indicator light to be illuminated. If the low-beam headlights is turned off, the fog lights will also be turn off automatically. Therefore, if the headlights are turned on at next opportunity, the fog lights do not illuminate.

If the high-beam headlights is turned on while the fog lights are on, the fog lights will be turned off. Then, if you switch the headlights from the high-beam to the low-beam, the fog lights will be turned on again.

NOTE: This description covers the fog lights only. In actual driving, the fog lights may be turned off due to the headlight automatic shut-down function. For the details of the headlight automatic shut-down function, refer to "Headlamp".
