Note
Each adjustment knob has 22 adjustment positions. The closer to position 0 the knob is set, the stiffer the suspension.

Turn the knob counterclockwise to the desired adjustment position.
Then follow the same procedure for the second tire.

The rear adjustment knobs are located above the tire inside the wheel housing. To access the rear adjustment knobs, the vehicle must be raised using a jack; see separate section.

The rubber cap is located above the adjustment knob.

Turn the adjustment knob clockwise or counterclockwise to change the adjustment position.
