Record your driving position to button 1, 2 or 3 before performing
the following:
Carry only the key (including the card key) to which you want to
link the driving position. If 2 or more keys are in the vehicle, the

To prevent unintended triggering of the alarm, open and close a
door once after a driving position has been recorded. (If a door is
not opened within 30 seconds after door lock switch is pressed, the
doors will be locked again and the alarm will automatically be set.)
