Simply twist the knob that's located on the turn signal lever (Left side of the steering wheel).
The knob that is located on the left should always be left on “AUTO”. This means that the headlights would turn on automatically whenever it gets dark. It will turn off automatically when you drive into a bright area.
To activate the high-beam, pull the left lever here towards you for a quick flash and push it away from you to switch on high-beam mode.
