Towing a trailer
Look after a detachable ball end in
accordance with its manufacturer's
operating instructions, to ensure that it
can be fitted and removed without diffi-
culty.
If a trailer tow hitch is installed,
the self-regenerating action of the
rear bumper system may not be able to
take effect.
<
The use of a stabilising device can be
recommended, particularly if the trailer
is a heavy one. Information can be
obtained from BMW Service.
Nose weight
This is the weight which the trailer
towbar exerts downwards on the ball
head of the car's trailer tow hitch (it can
for example be measured with bath-
room scales).
In Germany: a minimum nose weight of
25 kg (55 lb) is laid down by law.
The nose weight limit (see page 185)
may not be exceeded, but should
always be utilised to the full, in partic-
ular when towing large, heavy trailers
which are prone to swinging from side
to side.
The trailer's nose weight affects the
towing vehicle, and must not lead to the
car's gross weight limit or rear axle load
limit being exceeded if a trailer is being
towed. The car's payload limit is
reduced by the weight of the trailer tow
hitch and, if a trailer is being towed, by
its nose weight. The gross weight limit
for the combined car and trailer must
not be exceeded.
Towing a trailer
The permissible trailer load and nose
weight (towbar downthrust) are stated
in "Technical data", page 185. The
trailer load limit is also entered in the
car's registration papers. Consult BMW
Service regarding increased trailer
weights.
Loads:
When loading the trailer, make sure that
the weight is kept as low down as
possible and stowed if possible close to
the axle.
A low centre of trailer gravity makes the
outfit much more stable and safe to
drive.
Do not exceed either the trailer's gross
weight or the specified trailer load limit
for the car. The smaller value is the limit
which should be adhered to.
Before purchasing a trailer it is advis-
able to obtain a declaration from the
trailer manufacturer concerning the
effective trailer weight and trailer
payload limit.
