BMW Maintenance System
The maintenance system directs you to re‐
quired maintenance measures and thereby sup‐
ports you in maintaining road safety and the op‐
erational reliability of the vehicle.
Condition Based Service CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 87, can be displayed on the Control Dis‐
play.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
Therefore, hand your service specialist the re‐
mote control that you used most recently.Storage periods
Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/acti‐
vated-charcoal filter.

Vehicle care
Car care products
BMW recommends using cleaning and care
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 dan‐
gerous 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 affect
the vehicle's paintwork. Tailor the frequency
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.
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.Seite 223CareMobility223
