Trailer towing
When you couple up a trailer, PTS is deac-
tivated for the rear area as soon as you
have established an electrical connection
between your vehicle and the trailer.
!
Detach the trailer tow hitch when you do not
require it. The minimum detection range of PTS
to an obstacle refers to the bumper, not the ball
coupling.
