Trailer Towing - Mercedes-Benz 2005 M-Class Operator's Manual

Inspect frame, oil pan, brake hoses,
etc., as well as vehicle underbody for
possible damage.
Check tires for possible damage, clean
all exterior lamps, and conduct a brake
test.
Check for brush or branches caught in
the undercarriage.
They could increase the possibility of a
fire, as well as cut fuel and/or brake
lines, puncture rubber bellows of the
axles or drive shafts.
After continued operation in mud,
sand, water or other dirty conditions
clean the brake discs, wheels, brake
pads and check and clean axle joints.
