G
WARNING
If the ball coupling is not installed and secured
correctly the trailer may come loose. There is
a risk of an accident.
Install and secure the ball coupling as
described in the ball coupling installation
instructions. Make sure that the ball coupling
is installed and secured correctly before every
journey.
! Mercedes-Benz recommends that you
only use ball couplings that have been
tested and approved by Mercedes-Benz.
This helps to avoid damage to the vehicle. Cover cap
X
Pull protective cap :in the direction of the
arrow, out of ball coupling recess ;.
X Store protective cap :in a safe place.
X Observe the manufacturer's installation
instructions. G
WARNING
If the ball coupling is not installed and secured
correctly it can become detached while the vehicle is in motion and fall onto the road.
There is a risk of an accident and injury.
Install and secure the ball coupling as
described in the ball coupling installation
instructions. Make sure that the ball coupling
is installed and secured correctly before every
journey.
Coupling up a trailer
Observe the maximum permissible trailer
dimensions (width and length).
Most U.S. states and all Canadian provinces
require by law:
R safety chains between the towing vehicle
and the trailer. The chains should be cross-
wound under the trailer drawbar. They must
be fastened to the vehicle's trailer
coupling, not to the bumper or the axle.
Leave enough play in the chains to make
tight cornering possible.
R a separate brake system for certain types
of trailer.
R a safety switch for braked trailers. Check
the specific legal requirements applicable
to your state.
If the trailer detaches from the towing
vehicle, the safety switch applies the
trailer's brakes.
! Do not connect the trailer's brake system
(if featured) to the hydraulic brake system
of the towing vehicle, as the latter is
equipped with an anti-lock brake system.
Doing so will result in a loss of function of
the brake systems of both the vehicle and
the trailer.
i The vehicle's wiring harness features a
connection to the brake indicator lamp.
X Make sure that the automatic transmission
is set to position P.
X Apply the vehicle's parking brake.
