& WARNING Risk of being crushed and
becoming trapped when uncoupling a
trailer
When uncoupling a trailer with an engaged
inertia-activated brake, your hand may
become trapped between the vehicle and the
trailer drawbar.
Do not uncouple trailers with an
#
engaged overrun brake.

state of overrun
Uncoupling in a state of overrun can damage
the vehicle.
Do not uncouple trailers with an
#

vehicle lowers when the trailer cable is dis‐
connected.
This could result in you or other people
becoming trapped if your or their limbs are
between the vehicle body and the tyres or

Make sure nobody is underneath the
#
vehicle or in the immediate vicinity of
the wheel arches when you disconnect
the trailer cable.
