Attaching the tow bar/tow rope correctly
Attach the tow bar or tow rope to the tow
fitting; connecting it to other vehicle parts may
cause damage.◀▷Switch on the hazard warning system, de‐
pending on local regulations.▷If the electrical system has failed, clearly
identify the vehicle being towed by placing
a sign or a warning triangle in the rear win‐
dow.
Tow bar
The tow fittings used should be on the same
side on both vehicles.
Should it prove impossible to avoid mounting
the tow bar at an offset angle, please observe
the following:
▷Maneuvering capability is limited during cor‐
nering.▷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, always
use nylon ropes or nylon straps.
Attaching the tow rope correctly
Only secure the tow rope on the tow fit‐
ting; otherwise, damage can occur when it is se‐
cured on other parts of the vehicle.◀
Tow fitting
The screw-in tow fitting should always be car‐
ried in the vehicle. It can be screwed in at the
front or rear of the BMW. It is in the onboard ve‐
hicle tool kit located in a storage compartment
on the right side in the cargo area. Open the
cover.
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 ve‐
hicle can occur.◀

Upholstery material care
Vacuum regularly with a vacuum cleaner.
If they are very dirty, e.g., beverage stains, use a
soft sponge or microfiber cloth with a suitable
interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the ma‐
terial vigorously.
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
Use wheel cleaner, particularly during the winter
months. Do not use aggressive, acidic, strongly
alkaline or abrasive cleaners, or steam jets
above 140 ℉/60 ℃; follow the manufacturer's
instructions.
Chrome surfaces
Carefully clean components such as the radiator
grille or door handles with an ample supply of
water, possibly with shampoo added, particu‐
larly when they have been exposed to road salt.
Rubber components
Aside from water, treat only with rubber cleans‐
ers.
When cleaning rubber seals, do not use any sil‐
icon-containing car care products in order to
avoid damage or reduced noise damping.
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.▷Headliner.▷Lamp lenses.▷Instrument cluster cover.▷Matte black spray-coated components.▷Painted parts in the interior.
Clean with a microfiber cloth.
Lightly dampen the cloth with water.
Do not soak the headliner.
Do not use cleansers that contain alcohol
or solvents
Do not use cleansers that contain alcohol or sol‐
vents, 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.
Floor carpets and floor mats No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the area of motion of the pedals;
otherwise, the function of the pedals could be
impeded while driving
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 fixed in place.
Ensure that the floor mats are securely fastened
again after they were removed for cleaning, for
example.◀
