Attaching a trailer
Observe maximum permitted trailer di-
mensions (width and length).
Most states and all Canadian provinces re-
quire
ț safety chains between your tow vehicle
and the trailer.
The chains should be crisscrossed un-
der the trailer tongue. They must be at-
tached to the hitch receiver, and not to
the vehicle’s bumper or axle.
Be sure to leave enough slack in the
chains to permit turning corners.
ț a separate brake system at various
trailer weights.
ț a break-away switch on trailers with a
separate brake system.
The switch activates the trailer brakes
in the possible event that the trailer
might separate from the tow vehicle.
Towing a trailer
There are many different laws, including
speed limit restrictions, having to do with
trailer towing. Make sure that your rig will
be legal, not only for where you reside, but
also for where you will be driving. A good
source for this information can be the po-
lice or local authorities.
Note the following points, when driving
with the trailer:
ț In order to gain skill and an under-
standing of the vehicle’s behavior, you
should practice turning, stopping and
backing up in an area which is free from
traffic.
ț Before you start driving check the
ț trailer hitch
ț break-away switch
ț safety chains
ț electrical connections
ț lighting and tires
!
Do not connect a trailer brake system
(if trailer is so equipped) directly to the
vehicle’s hydraulic brake system, as
your vehicle is equipped with antilock
brakes. If you do, neither the vehicle’s
brakes nor the trailer’s brakes will func-
tion properly.
i
The provided vehicle electrical wiring
harness for trailer towing has a brake
signal wire (color orange) for hook-up
to a brake controller.
You should consider using a trailer
sway control system. For further infor-
mation see your authorized
Mercedes-Benz Light Truck Center.
