(With auto-light control)
When the position lights are turned on with the ignition switched ON, the brightness of the dashboard illumination is dimmed. However, when the light sensor detects that the surrounding area is bright such as when the position lights are turned on in the daytime, the dashboard illumination does not dim.
NOTE
When the ignition is switched ON in the early evening or at dusk, the dashboard illumination is dimmed for several seconds until the light sensor detects the brightness of the surrounding area, however, the dimmer may cancel after the brightness is detected.
Refer to Headlights.
The brightness of the instrument cluster and dashboard illuminations can be adjusted by rotating the knob.

Function for cancelling illumination dimmer
The illumination dimmer can be canceled by rotating the dashboard illumination knob to the right until a beep sound is heard while the instrument cluster is dimmed with the ignition switched ON.
If the instrument cluster's visibility is reduced due to glare from surrounding brightness, cancel the illumination dimmer.
