2012 BMW 640I CONVERTIBLE fuel

To guard against discoloration, such as from
clothing,
provide leather care roughly every two
months.
Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
layer of the leather surface.
Suitable care products are available from the
service center.
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.
Clean with a microfiber cloth.
Moisten the cloth lightly and use plastic
cleanser, if necessary.
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. Seite 256
