When the parking lights are turned on and the ignition switch is in ON *1, you can use the brightness control knob to adjust instrument panel brightness.
Brighten: Turn the knob to the right.
Dim: Turn the knob to the left.
You will hear a beep when the brightness reaches minimum or maximum. Several seconds after adjusting the brightness, you will be returned to the previous screen.
Brightness level indicator
The brightness level is shown on the display while you are adjusting it.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an ignition switch.
Instrument panel brightness varies, depending on whether the exterior lights are on or off. The instrument panel dims to reduce glare when they are on.
Pressing the (TRIP) knob or the (display/ information) button* switches the display.
If you turn the knob to the right until the brightness display is up to max, the beeper sounds. This cancels the reduced instrument panel brightness when the exterior lights are on.
