proper tire maintenance, and it is the driver's 
responsibility to maintain correct tire pressure, 
even if underinflation has not reached the level 
to trigger illumination of the TPMS low tire 
pressure indicator.
The TPMS malfunction indicator is combined 
with the low tire pressure indicator. When the 
system detects a malfunction, the indicator will 
flash for approximately one minute and then 
remain continuously illuminated. This 
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists. 
When the malfunction indicator is illuminated, 
the system may not be able to detect or signal 
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate 
tires or wheels on the vehicle that prevent the 
TPMS from functioning properly. Always check 
the TPMS malfunction indicator after replacing 
one or more tires or wheels on your vehicle to 
ensure that the replacement or alternate tires 
and wheels allow the TPMS to continue to func-
tion properly.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed 
range, e.g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes 
very direct. In the higher speed range, on the 
other hand, the steering angle is reduced more 
and more. This improves the handling capability 
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle 
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is 
switched off, refer to page

.
Malfunction
The warning lamp lights up yellow and 
a message is shown on the Control 
Display. The active steering is no 
longer operational. At low speed, larger steering 
wheel movements are required, while the vehi-
cle reacts more sensitively to steering wheel 
movements in the higher road speed range. 
The stability-promoting intervention can also 
be deactivated. Proceed cautiously and drive 
defensively. Have the system checked.
