When the front fog lamp switch is turned to ON with
the tail lamp or the headlamp on (the tail lamp switch
or the headlamp switch is ON), the fog lamp relay
turns on, and the fog lamps will illuminate.
If the tail lamps or the headlamps are turned off with
the lighting switch OFF while the fog lamps are on,
the front fog lamps turn off at the same time to
prevent unattended operation.
If the tail lamps are turned off by the headlamp
automatic shutdown function, the fog lamps turn off
at the same time. However, if the tail lamps illuminate
again, the fog lamps do not.
The front fog lamps are controlled by the Smart
Wiring System (SWS). For troubleshooting, refer to
