There are 2 possibilities for this feature.

If one guide does not work on your car, try the other one.

Original Guide:

1 - Put ignition on, lock and unlock the door 3 times.
2 - Ignition off, lock and unlock door 3 times.
3 - Put ignition back on and you should hear a bleep.
4 - lock and unlock once more.

Motion lock's should work now when you drive off.



Alternate Guide:

1. Turn on the ignition but don't start engine.
2. Lock door by pushing in the button, then pull handle slightly x3.
3. Turn the ignition off.
4. Do the exact same as step 2.
5. Turn on the ignition but don't start engine, you should hear a beep.
6. Lock door by pushing in the button, then pull the handle slightly and another beep should be heard, job done.

When pulling the handle on all the above instructions, do not open the door, just pull it slightly. It may not work first time but keep trying it will work. Good luck.
