less external light is required to activate
the external lights.Activation

detect the presence of fog. Therefore
under these circumstances, these lights
must be turned on manually.
When the lights are turned on by the
sensor, the fog lights (for versions/
markets, where provided) and the rear
fog lights may be turned on.
When the lights are automatically
switched off, the front and rear fog
lights (if activated) are also switched off.
The next time the lights are switched
