Where is the locking wheel nut on a citroen c4 Picasso?

The locking wheel nut on a Citroen C4 Picasso is usually located on one of the lug nuts of each wheel. It is a lug nut that has a different shape or pattern than the other lug nuts, and it may also be painted a different color. The locking wheel nut is designed to prevent the removal of the wheels without a special key, which is included with the vehicle.

Here are the steps on how to remove the locking wheel nut on a Citroen C4 Picasso:

1. Park your vehicle on a level surface and engage the parking brake.

2. If necessary, jack up the vehicle so that you can access the lug nuts fully. Use jack stands to support the vehicle securely before crawling underneath it.

3. Locate the locking wheel nut on the wheel you want to remove.

4. Insert the special key included with your vehicle into the locking wheel nut. Be sure to seat the key properly so that it can engage the tumblers in the keyhole.
