tance during panic stops. This system 
exploits all of the benefits provided by ABS. 

Do not reduce the pressure on the brake 
pedal for the duration of the brake applica-
tion. When the brake pedal is released, 
DBC is deactivated. 

In the event of a malfunction, the 
warning lamp in the instrument 
cluster lights up yellow. 

Have the system checked and repaired at 
your BMW center as soon as possible. 
Please note any information that appears 
on the Control Display.

Active roll stabilization minimizes body roll 
and optimizes vehicle stability during cor-
nering and evasive maneuvers. 

Dynamic stabilizers at the front and rear 
axles form the basis for active roll stabiliza-
tion. Suspension compliance adapts to suit 
driving conditions, varying from perfor-
mance-oriented during cornering to 
smooth and comfort-oriented when the 
vehicle is proceeding in a straight line. 

The system assumes operational status 
each time you start the engine. 

During vehicle operation, the system con-
tinuously runs through closed-loop control 
cycles lasting only fractions of a second.

The symbol in the instrument clus-
ter lights up and a message 
appears on the Control Display. 

Please note any supplementary information 
that appears there. 
You can find more information on the 
Check Control starting on page 

If the active roll stabilization system is 
deactivated in response to malfunc-

tion, please remember to adapt your speed 
accordingly, especially in curves. 
The suspension will be noticeably softer 
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds. 
If a message stating that you should stop 
appears on the Control Display in addition 
to the red symbol, stop immediately and 
switch off the engine. In this case the oil 
level in the reservoir may have dropped 
below the minimum, possibly owing to a 
leak in the hydraulic system. 
Please note any supplementary information 
that appears on the Control Display.

The Flat Tire Monitor keeps track of the 
inflation pressures in the four fitted tires as 
you drive. The system provides an alert 
whenever the inflation pressure drops sig-
nificantly in relation to the pressure in 
another tire.

The check of the tire inflation pressure is 
based on monitoring the relative speeds of 
the wheels. A flat tire is detected and 
reported on the basis of a deviation in cer-
tain speed ratios. 

So that the Flat Tire Monitor can learn the 
correct inflation pressure, please perform 
the following: 

1.

Check the inflation pressures in all tires

2.

Compare with the inflation pressure 
table on page 

 and correct if neces-

sary 

3.

Initialize the system. 

The Flat Tire Monitor cannot indicate 
sudden severe tire damage caused 

by outside factors and does not detect a
