Stowing the ball holder
WARNING
When not in use, the detachable ball holder should always be properly stowed
in the designated location under the floor of the cargo compartment.
Driving with a trailer
When towing a trailer, the original ball holder or equivalent should be used.

The ball mount must fall within the geometric limits for the towbar, for both
distance
and height
. Geometric limits are described on
a type plate located on the towbar.
The greater the distance between the load and the bicycle holder, the greater
the load on the hitch and on the vehicle.
Keep the following points in mind:
Mount the heaviest bicycle closest to the vehicle...
There are a number of things to consider when towing a trailer, such as the
towbar, the trailer and how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehicle's curb weight...
