Manually unlocking and locking the 
transmission lock
In the event of a power supply interruption, e.g. 
when the battery is dead or disconnected or 
when there is an electrical malfunction, the 
transmission lock must be released manually; 
otherwise, the rear wheels are locked and the 
vehicle cannot be towed.

ing the transmission lock; otherwise, 
there is a danger of the vehicle rolling.<
The transmission lock should only be released 
for towing. Reengage the transmission lock 
after parking the vehicle at its destination.

brake, refer to page60.

Condition Based Service does not con-
tinue counting down to the next service 
during periods when the vehicle is stored with 
the battery disconnected or the battery switch 
in the OFF position. 
It is therefore important, independent of the dis-
play, to change the brake fluid at least every 
2years. 
The same is true for other time-dependent 
maintenance procedures.<

BMW Maintenance System
The BMW Maintenance System serves to 
retain the operating and road safety of your 
BMW. The service schedule also includes oper-
ations related to the vehicle's comfort and con-
venience features, such as replacement of the 
filters for the inside air. The aim is to optimize 
maintenance procedures with a view to reduc-
ing 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 inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent 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 requirements, the system forms 
the basis for trouble-free driving.
On the Control Display, you can have the 
remaining times and distances for selected 
maintenance procedures and any legally man-
dated deadlines displayed, refer to page78:
>Engine oil
>Brakes, separate for front and rear
>Microfilter
>Brake fluid
>Spark plugs>Vehicle check
>Legally prescribed inspections depending 
on national regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control 
while you are driving. After accessing the data 
stored in the vehicle key, your BMW Service 
Advisor can suggest precisely the right array of 
service procedures for your own individual vehi-
cle. This is why it is important when you take 
your vehicle in for service to give the BMW Ser-
vice Advisor the last remote control you used 
for driving.
Storage periods with the battery discon-
nected are not taken into account by the 
CBS maintenance system. If this occurs, have a 
BMW center update the time-dependent main-
tenance procedures, such as checking brake 
fluid and if necessary engine oil and the micro/
activated charcoal filter.<
