Notes on towing a trailer
Mercedes‑AMG vehicles: be sure to observe
the notes in the Supplement. Otherwise, you
may fail to recognize dangers.

ment. Otherwise, you may fail to recognize dan‐
gers.
& WARNING Danger of accident due to
unsuitable ball coupling
If you install an unsuitable ball coupling,
overloading of the trailer hitch and rear axle
will be the result. This is particularly the case
if the ball coupling is relatively long or angled
differently.
Driving and parking 247
The handling characteristics may be heavily
impaired and the trailer can become
detached. There is a risk of fatal injury.
Only install a ball coupling that meets
#
the permitted dimensions and has been
designed for the trailer operation
requirements.
Do not modify the ball coupling or the
#
trailer hitch.
The values approved by the manufacturer can be
found on the identification plates and in the
"Technical data" section under "Trailer hitch" for
the towing vehicle ( page 503).
