Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:▷Maneuvering capability is limited going
around corners.▷The tow bar will generate lateral forces if it
is secured with an offset.
Tow rope
When starting to tow the vehicle, make sure
that the tow rope is taut.
To avoid jerking and the associated stresses
on the vehicle components when towing, al‐
ways use nylon ropes or nylon straps.
Tow fitting
The screw-in tow fitting should always be car‐
ried in the vehicle.
The tow fitting can be screwed in at the front
or rear of the BMW.
The tow fitting is located in the onboard vehi‐
cle tool kit under the cargo floor panel.
Tow fitting, information on use
▷Use only the tow fitting provided with
the vehicle and screw it all the way in.▷Use the tow fitting for towing on paved
roads only.▷Avoid lateral loading of the tow fitting, e.g.,
do not lift the vehicle by the tow fitting.
Otherwise, damage to the tow fitting and the
vehicle can occur.◀
Screw thread for tow fitting
Push out the cover by pressing on the top
edge.
Tow-starting
Steptronic transmission Do not tow-start the vehicle.

Damage from Velcro® fasteners
Open Velcro® fasteners on pants or
other articles of clothing can damage the seat
covers. Ensure that any Velcro® fasteners are
closed.◀
Caring for special components
Light-alloy wheels When cleaning the vehicle, use only neutral
wheel cleaners having a pH value from 5 to 9.
Do not use abrasive cleaning agents or steam
jets above 140 ℉/60 ℃. Follow the manufac‐
turer's instructions.
Aggressive, acidic or alkaline cleaning agents
can destroy the protective layer of adjacent
components, such as the brake disk.
Chrome surfaces Carefully clean components such as the radia‐
tor grille or door handles with an ample supply of water, possibly with shampoo added, partic‐
ularly when they have been exposed to road
salt.
Rubber components Aside from water, treat only with rubber
cleansers.
When cleaning rubber seals, do not use any
silicon-containing car care products in order to
avoid damage or noises.
Fine wood parts
Clean fine wood facing and fine wood compo‐
nents only with a moist rag. Then dry with a
soft cloth.
Plastic components These include:▷Imitation leather surfaces.▷Roofliner.▷Lamp lenses.▷Instrument cluster cover.▷Matt black spray-coated components.▷Painted parts in the interior.
Clean with a microfiber cloth.
Dampen cloth lightly with water.
Do not soak the roofliner.
No cleansers that contain alcohol or sol‐
vents
Do not use cleansers that contain alcohol or
solvents, such as lacquer thinners, heavy-duty
grease removers, fuel, or such; this could lead
to surface damage.◀
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Chemical cleaning
Do not clean chemically; this can destroy
the webbing.◀
Use only a mild soapy solution, with the safety
belts clipped into their buckles.
Do not allow the reels to retract the safety
belts until they are dry.
Carpets and floor mats No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Floor mats can be removed from the car's inte‐
rior for cleaning.
