1. Make sure the headlights are on.
2. Locate the fog light switch on the dashboard. It is usually located near the headlight switch.
3. Turn the fog light switch to the "on" position. The fog lights will turn on.
If the fog lights do not turn on, check the fuses to make sure they are not blown. The fuse for the fog lights is usually located in the fuse box under the hood of the car.
