Releasing the parking lock manually
In the event of an electrical malfunction, it is possible to release the selector lever lock manually to move it out of position P, e.g. if you wish to tow the vehicle away.

Do not use any sharp-edged objects to remove the selector lever gaiter from
the center console. This could damage the selector lever gaiter.
- Apply the parking brake.
- Pry off selector lever gaiter : with a flat, blunt object, (e.g. a screwdriver wrapped in cloth) from the right-hand edge, pulling it up and out.
- Press release buttons ; down and simultaneously move the selector lever out of position P.
The selector lever can now be moved freely until it is returned to position P.
