Towing a trailer
Information about permissible trailer loads
appears on page 217 onwards. BMW Service
will provide information about ways to increase
these load ratings.

by the cutout from beneath, and pull off
to the rear.
Fitting
Hold the cover flap against the trim from
beneath, push it in the guide and press on fully.
Trailer tow hitch*
Cars fitted with a trailer tow hitch prior to deliv-
ery are equipped with uprated suspension at
the rear axle and a more powerful engine cool-
ing system, as appropriate for the model.
Look after a detachable ball end in accordance
with the manufacturer's operating instructions,
to ensure that it can be fitted and removed with-
out difficulty.
Due to the body reinforcements at the rear end
of the car, the effect of the regenerable bumper
system is limited.
Fitting and removing
The ball hitch is in the luggage compartment or
load area, beneath the floor panel flap.
The procedure for fitting and removing the ball
hitch is described in the enclosed manufac-
turer's operating instructions.
Before a journey
Nose weight
It is important to ensure that the nose weight is
never less than a minimum of 25 kg, approx.
55 lb. Information about nose weight limits
appears on page 217 onwards. The nose
weight should be kept close to this limit.
The trailer's nose weight affects the towing
vehicle and thus increases its weight. The
weight of the trailer tow hitch and the nose
weight reduce the maximum payload of your
BMW. Please ensure that these do not cause
the gross weight limit of the towing vehicle to be
exceeded if a trailer is being towed.
Loads
When loading the trailer, make sure that
the weight is kept as low 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 permitted
gross weight or the specified permitted towing
load for the car. The smaller value is the limit
which should be adhered to.
Tyre pressures
Take great care to check the BMW's and the
trailer's tyre pressures. For the car, the tyre
inflation pressures for heavy loads apply, see
page 182. After each correction of the tyre
pressures, reinitialise the Run Flat Indicator,
see page 87.
For the trailer, comply with the manufacturer's
specifications.
Run Flat Indicator
Reinitialise the Run Flat Indicator after a trailer
has been attached or detached, see page 87.
Outside mirrors
Two outside mirrors which bring both rear cor-
ners of the trailer into your field of view are
required by law. Mirrors of this kind can be
obtained from BMW Service.
