How to use the air suspension:

Adjust the air suspension for each axle to suit the load you are carrying; the lighter the load, the less need there is for lowered axles, whereas a heavier load requires more axles to be lowered to support the weight and distribute it effectively.

To lower the first (rear) and third (last fixed) axles, use the controls in Group 1; you can use the analog stick (on consoles) or the mouse on PC (or, if available, the J/N and K/M keys).

Also within Group 1, you can operate the steering axle suspension; this is controlled via the analog stick (on consoles) or the mouse only (on PC).

In control Group 2, you can adjust the height of the center axle, allowing you to compensate for uneven terrain and raise the trailer's ground clearance. You can use the analog stick (on consoles) or the mouse on PC (or, if available, the J/N and K/M keys) for this operation.
