Key/remote control
1Remote controls with integrated key.
They specify the functions of the Key
Memory. Individual functions of your
vehicle may behave differently depend-
ing on the remote control used.
To differentiate, you can mark the
remote controls using the color-coded
decals you received on taking delivery
of the vehicle
There is an extended-life battery
in every remote control which is
charged automatically in the ignition
lock as you drive.
If you have any remote control units that
are not being used on a regular basis,
you should therefore remember to
recharge these units by using them to
drive the vehicle for an extended period
at least once every six months, also
refer to page 36.
With Comfort Access, there is a battery
in every remote control. For instructions
on changing batteries, refer to
page37.<

Batteries
To avoid possible short circuits, after
removing a battery you should never
allow it to come into contact with metallic
surfaces of any kind. This is why you should
handle charged batteries with care, in par-
ticular if you place batteries, e.g. in jacket
or shirt pockets that contain metal objects.
If you are in an environment where there is
a risk of explosion, do not remove the bat-
tery from the device, as otherwise sparks
from your battery could cause explosions
or fire.<
Disposing of used batteries
Return used batteries to a recycling
collection point or to your BMW cen-
ter.<

Maintenance
The BMW Maintenance
System
The BMW Maintenance System serves to
retain the operating and road safety of your
BMW. The service schedule also includes
operations related to the vehicle's comfort
and convenience features, such as
replacement of the filters for the inside air.
The aim is to optimize maintenance with
regard to reducing the cost of running the
vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
Sensors and special algorithms take the
different driving conditions of your BMW
into account. As a result, Condition Based
Service determines the current and future
maintenance requirements. By letting you
define a service and maintenance regimen
that reflects your own individual require-
ments, the system forms the basis for trou-
ble-free driving.
The service requirement display, refer to
page82, shows you the times or distances
remaining until the deadlines for selected
service and maintenance procedures, as
well as legally-mandated inspections:
>Engine oil
>Brakes, separate for front and rear
>Microfilter/activated-charcoal filter >Brake fluid
>Spark plugs
>Vehicle check
>Coolant
>Legally prescribed inspections depend-
ing on national regulations.
Your vehicle stores this information contin-
uously in the ignition key while the vehicle
is being driven. After accessing the data
stored in the vehicle key, your BMW service
advisor is able to suggest precisely the
right array of service procedures for your
own individual vehicle. You should there-
fore hand over to the BMW service advisor
the key you last used to drive when you
take your vehicle for service.
Storage periods with the battery dis-
connected are not taken into account
by the CBS maintenance system. Have the
time-dependent service and maintenance
operations, such as brake fluid and cool-
ant, and if necessary engine oil and the
micro/activated charcoal filter, updated by
a BMW center.<

age when changing bulbs, observe any
