Coupling and Uncoupling
4. Detach the brake pipes and cables for lighting and ABS/EBS.
5. If fitted, detach the safety hook or padlock.
6. Unlock the fifth wheel by pulling out the handle. The hook is now opened and
ready for uncoupling.
7. Slowly drive the tractor from under the semi-trailer.
Note:
On vehicles with air suspension, the remote control electronic height control is used
for coupling/uncoupling the trailer. When coupling, the vehicle can be brought to the
correct coupling height, or the semi-trailer can be lifted before the supports are
wound down.
Important
After coupling or uncoupling a semi-trailer, always press the remote control key or
the appropriate key on the instrument panel for automatic resetting of the correct
driving height. This will set the correct driving height automatically.
Tractors may be fitted with a small towing hook at the rear end of the chassis. This
towing hook must only be used for light shunting work (max. 4300 kg).
