CareVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Car washes
General information
Regularly remove foreign objects such as
leaves in the area below the windshield when
the hood is raised.
Wash your vehicle frequently, particularly in
winter. Intense soiling and road salt can dam‐
age the vehicle.
Hints Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
Holding them too close or using excessively
high pressures or temperatures can cause
damage or preliminary damage that may then
lead to long-term damage.
Follow the user's manual for the high-pressure
washer.◀
Cleaning sensors/cameras/hardtop with
high-pressure washers
When using high-pressure washers, do not
spray the seals of the lowerable hardtop, sen‐
sors and cameras external to the vehicle, e.g.,
Park Distance Control, for extended periods oftime and only from a distance of at least
12 in/30 cm.◀
Automatic car washes
Hints Do not use high pressure washing sys‐
tems
With washing systems operating at high pres‐
sures and nozzle positions close to the win‐
dows, drops of water can penetrate.◀▷Give preference to cloth car washes or
those that use soft brushes in order to
avoid paint damage.▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 70, to avoid unintentional wiper acti‐
vation.▷In some cases, an unintentional alarm can
be triggered by the interior motion sensor
of the alarm system. Follow the instruc‐
tions on avoiding an unintentional alarm,
refer to page 44.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀

▷Do not rub dry and do not use abrasive or
acidic cleansers.▷Soak areas that have been dirtied e. g.,
from insects, with shampoo and wash off
with water.▷Thaw ice with de-icing spray; do not use an
ice scraper.
Lowerable hardtop
When the wet hardtop is opened, water drop‐
lets can run into the cargo area. Remove any
objects in the cargo area beforehand to pre‐
vent water spotting or soiling.
After washing the vehicle
After washing the vehicle, apply the brakes
briefly to dry them; otherwise, braking action
can be reduced and corrosion of the brake
discs can occur.
Completely remove all residues on the win‐
dows, to minimize loss of visibility due to
smearing and to reduce wiper noises and
wiper blade wear.
Vehicle care
Car care products BMW recommends using care and cleaning
products from BMW, since these have been
tested and approved.
Car care and cleaning products
Follow the instructions on the container.
When cleaning the interior, open the doors or
windows.
Only use products intended for cleaning vehi‐
cles.
Cleansers can contain substances that are
dangerous and harmful to your health.◀
Vehicle paint
Regular care contributes to driving safety and
value retention. Environmental influences in
areas with elevated air pollution or natural con‐
taminants, such as tree resin or pollen can af‐
fect the vehicle's paintwork. Tailor the fre‐
quency and extent of your car care to these
influences.
Aggressive substances such as spilled fuel, oil,
grease or bird droppings, must be removed im‐
mediately to prevent the finish from being al‐
tered or discolored.
Leather care
Remove dust from the leather often, using a
cloth or vacuum cleaner.Seite 221CareMobility221
Online Edition for Part no. 01 40 2 956 860 - X/14

Otherwise, particles of dust and road grime
chafe in pores and folds, and lead to increased
wear and premature degradation of the leather
surface.
To guard against discoloration, such as from
clothing, provide leather care roughly every
two months.
Clean light-colored leather more frequently be‐
cause soiling on such surfaces is substantially
more visible.
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 upholstery is very dirty, e.g., with 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
material 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 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 partsClean 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.
