Acura 2013 MDX - Manual (Page 144)

The ignition switch has four positions:
LOCK (0), ACCESSORY (I), ON (II),
and START (III).
LOCK (0) － You can insert or remove
the key only in this position. To turn
the key to the LOCK (0) position, the
shift lever must be in Park, and you
must push the key in slightly.
If the front wheels are turned, the anti-
theft lock may make it difficult to turn
the key. Firmly turn the steering wheel
to the left or right as you turn the key.
ACCESSORY (I) － You can operate
the audio system and the accessory
power sockets in this position.
ON (II) － This is the normal key
position when driving. Several of the
indicators on the instrument panel
come on as a test when you turn the
ignition switch from the
ACCESSORY (I) to the ON (II)
position.
START (III) － Use this position
only to start the engine. The switch
returns to the ON (II) position when
you let go of the key.
You will hear a reminder beeper if
you leave the key in the ignition
switch in the LOCK (0) or the
ACCESSORY (I) position and open
the driver's door. Remove the key to
turn off the beeper.
The shift lever must be in Park
before you can remove the key from
the ignition switch.
