Trailer Towing - Mercedes-Benz Light Truck ML 320 Operator's Manual

Trailer Towing

Warning!
Failure to use proper equipment and
driving technique can result in a loss
of vehicle control when towing a
trailer.
Improper towing or failure to follow
the instructions contained in this
guide can result in serious injury.
Follow the guidelines below carefully
to assure safe trailer operation.
Ask your authorized Mercedes-Benz
light truck dealer should you require
an explanation or information
contained in this guide.
Trailer Hitches
Only install a trailer hitch receiver
approved for your vehicle. For
information on availability and
installation, please see your authorized
Mercedes-Benz light truck dealer.
The bumpers on your vehicle are not
designed for use with clamp-type
hitches. Do not attach rental hitches or
other bumper-type hitches to them.
To reduce the possibility of damage,
remove the hitch ball adaptor from the
receiver when not in use.
Electrical Connections
The vehicle is prewired to accept the
seven-wire harness included in the
Mercedes-Benz approved trailer hitch
receiver kit. An additional four-pole
conversion plug is included in the
Mercedes-Benz supplied trailer hitch
receiver kit. For further information,
please see your authorized Mercedes-
Benz light truck dealer.
In order to prevent possible damage to
the vehicle's electrical system by
incorrectly installing the trailer wiring
plug, we recommend having the
harness connected at an authorized
Mercedes-Benz light truck dealer.
