Caution! Adjustment of the steering column position should only be performed when the vehicle is stationary.
Caution! For safety reasons, the locking handle must always be firmly pressed down to prevent the steering column from suddenly changing position while driving.

The steering column can be infinitely adjusted in height. To do this, press the locking handle located to the left of the steering column upwards and set the steering column in the desired position. Finally, press the locking handle downwards with force.
