Checking weights of vehicle and trailer
ț To assure that the tow vehicle and trail-
er are in compliance with the maximum
permissible weight limits have the load-
ed rig (tow vehicle including driver, pas-
sengers and cargo, trailer fully loaded)
weighed on a commercial scale.
ț Check the vehicle’s front and rear
Gross Axle Weight (GAW), the GTW and
TW.
The values as measured must not be
exceeded, according to the weight list-
ed under “Vehicle and trailer weight
and ratings”.
Attaching a trailer
Observe maximum permitted trailer
dimensions (width and length).
Most states and all Canadian provinces
require
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.
Make 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.
!
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 an authorized
Mercedes-Benz Light Truck Center.
