DRIVING TIPS
System limits
General information
The maximum speed is limited to approx.
6 mph/10 km/h.
A warning is given at a speed of approx.
4 mph/7 km/h.
If the maximum speed is exceeded, the func-
tion is interrupted.
Functional limitations
When maneuvering, the following can restrict
this function or lead to a collision:
▷ Accessories on the trailer tow bar, e.g., a
bicycle carrier.
▷ Tow bar and trailer with unusual shapes.
▷ Unsuitable removable trailer hitches.
Trailers with fifthwheel steering are not sup-
ported.
Trailer stabilization control
Principle
Trailer stabilization control helps by absorbing
the swinging movements of the trailer.
The system detects swinging and automati-
cally brakes the vehicle quickly in order to leave
the critical speed range and stabilize the car-
trailer combination.
General information
If the trailer power socket is occupied but a
trailer has not been hitched, the system can
also become active in extreme driving situa-
tions, e.g., when using a bicycle rack with light-
ing.
Functional requirement
The system is functional at speeds beginning
at approx. 40 mph/65 km/h while a trailer is

being towed and the trailer power socket is
occupied.
System limits
The system cannot intervene or not intervene
in time in the following situations, for instance:
▷ If a trailer jackknifes suddenly, for instance
on slippery roads or loose surfaces.
▷ If a trailer with a high center of gravity tilts,
before swinging is detected.
▷ If Dynamic Stability Control is deactivated
or has malfunctioned.
▷ When the power consumption of a trailer is
too low, for instance due to tail lights with
LED technology, to be detected by the sys-
tem.
Brake Controller
The vehicle manufacturer recommend having
a brake controller installed by an authorized
service center or another qualified service cen-
ter or repair shop.
Information on brake controller installation can
be obtained from an authorized service center
or another qualified service center or repair
shop.
Rear-mounted luggage rack
Principle
The ball head of the trailer hitch can be used
as a mount for rear-mounted luggage racks,
such as bicycle rack systems.
General information
Rear-mounted luggage racks that are classi-
fied by the manufacturer of the vehicle to be
suitable are available as optional accessories.
Bicycle rack systems can be used for a maxiu-
mum of three bicycles.
