Trailer weight
Maximum recommended trailer weights for
different gradients, with a view to comfort
and drivability for manual and automatic
cars, are shown on the drawing.
Make sure you are familiar with the law
regarding speed limits for towing, maxi-
mum trailer weights, trailer-braking
requirements, and also any special
driving-licence provisions
(see also page 259).
The specified trailer weights and gradients
assume that the journey starts at the hill and
therefore apply only to short periods.
Recommendations for driving in hilly
terrain
The following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86°F (30°C).
The following time limits are based on the
capacity of the cooling system in hot
weather, i.e. approximately 104°F (40°C).
WARNING
• When towing a trailer, do not attempt
to negotiate a hill having a gradient in
excess of 15 %. The weight distribu-
tion over the front wheels of the car will
be insufficient to prevent wheelspin,
making further progress impossible.
• In addition, the parking brake may not
always be able to hold the car and
trailer securely, with the result that the
wheels can start to slide downhill.
• Always apply the trailer’s handbrake
when unhitching it. There is otherwise
a risk of personal injury or damage to
the bumper should the trailer start to
roll.
