Maintenance  
Storage periods  
Vehicle equipment  
Storage periods during which the vehicle bat‐  
tery was disconnected are not taken into ac‐  
count.  
All standard, country-specific and optional  
equipment that is offered in the model series is  
described in this chapter. Therefore, equip‐  
ment is also described that is not available in a  
vehicle, e. g., because of the selected optional  
equipment or country variant. This also applies  
for safety-related functions and systems.  
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/  
activated-charcoal filter.  
BMW Maintenance System  
Service history  
The maintenance system directs you to re‐  
quired maintenance measures and thereby  
supports you in maintaining road safety and  
the operational reliability of the vehicle.  
Perform maintenance work at the service cen‐  
ter and have them recorded in the vehicle data.  
The entries are like a service booklet of the  
documentation of regular maintenance.  
Displaying entered maintenance work on the  
Control Display, refer to page 81.  
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.  
Service and Warranty  
Information Booklet for US  
models and Warranty and  
Service Guide Booklet for  
Canadian models  
Please consult your Service and Warranty In‐  
formation Booklet for US models and Warranty  
and Service Guide Booklet for Canadian mod‐  
els for additional information on service re‐  
quirements.  
The system makes it possible to adapt the  
amount of maintenance you need to your user  
profile.  
Detailed information on service requirements,  
refer to page 80, can be displayed on the Con‐  
trol Display.  
Service data in the remote control  
Maintenance and repair should be performed  
by your service center. Make sure to have reg‐  
ular maintenance procedures recorded in the  
vehicle's Service and Warranty Information  
Booklet for US models, and in the Warranty  
and Service Guide Booklet for Canadian mod‐  
els. These entries are proof of regular mainte‐  
nance.  
Information on the required maintenance is  
continuously stored in the remote control.  
Your service center will read out this data and  
suggest the right array of service procedures  
for your vehicle.  
Therefore, hand your service specialist the re‐  
mote control with which the vehicle was driven  
most recently.

Socket for OBD Onboard  
Diagnosis  
Position  
There is an OBD socket on the driver's side for  
checking the primary components in the vehi‐  
cle emissions.  
Emissions  
The warning lamp lights up:  
Emissions are deteriorating. Have  
the vehicle checked as soon as  
possible.  
Canadian model: warning light indi‐  
cates the engine symbol.  
The warning lamp flashes under certain  
circumstances:  
This indicates that there is excessive mis‐  
firing in the engine.  
Reduce the vehicle speed and have the  
system checked immediately; otherwise,  
serious engine misfiring within a brief pe‐  
riod can seriously damage emission con‐  
trol components, in particular the catalytic  
converter.  
Fuel cap  
The indicator lamp lights up.  
If the fuel cap is not properly tightened,  
the OBD system may conclude that  
fuel vapor is escaping. If the cap is then tight‐  
ened, the display should go out in a short time.
