Acura 2009 TSX - Manual (Page 122)

When you turn the knob, the multi-
information display changes to
vertical bars that show you the
current level.
You will hear a tone when you reach
the maximum or minimum
brightness. The brightness level
goes out about 5 seconds after you
stop adjusting.
To reduce glare at night, the
instrument panel illumination dims
when you turn the light switch to
or position. Turning the
knob to the right until you hear a
tone will cancel the reduced
brightness.
The instrument panel will illuminate
with reduced brightness when you
unlock and open the driver’s door.
The brightness will increase slightly
when you insert the key in the
ignition switch, then go to normal
brightness when you turn the
ignition switch to the ON (II)
position.
If you do not insert the key in the
ignition switch after opening the
driver’s door, the illumination turns
off about 30 seconds after you close
the door.
If you insert the key but do not turn
the ignition switch to the ON (II)
position, the illumination turns off in
about 10 seconds.
