Headlamp High/Low-Beam Changer
Push the turn signal/lane change lever away from you to turn the high beams on. Pull the lever toward you and then release it to return to low beams.
If the vehicle is turned off while the high beams are on, they will come on the next time the vehicle is started.
This indicator light turns on in the instrument panel cluster when the high–beam headlamps are on.
