Never adjust the instrument cluster while driving. This could result in loss of control and lead to an accident that may cause death, serious injury, or property damage.

The brightness of the instrument panel illumination changes by pressing the upper or lower part of the switch when the ignition switch is in the ON position and when the parking lights are turned on.

If the brightness reaches to the maximum or minimum level, a chime will sound (if equipped).
