Indication of a flat tire
The warning lamp lights up in red
and a message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat tire
or extensive inflation pressure loss.
1. Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2. Identify damaged tire
If identification is not possible,
contact your BMW center.
<
3. Replace the damaged wheel, refer to
Changing a wheel on page
184 .
Vehicles with run-flat tires:
1. Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
side walls of the run-flat tires,
inflation pressure loss can not usually
be recognized from the outside, refer to
Run-flat tires on page
170 .

2. To continue driving, comply with the
instructions for driving with damaged
tires on page

Malfunction
The warning lamp lights up yellow
and a message appears on the
Control Display. The Flat Tire Moni-
tor has a malfunction or has failed. Have
the system checked as soon as possible.
Active steering *
The concept
The active steering is a system that actively
varies the steering angle of the front wheels
in relation to the steering wheel move-
ments.
When you are driving in the low road speed
range, e.g. in a town or when parking, the
steering angle is reinforced, i.e. the steer-
ing becomes very direct. In the higher
speed range, on the other hand, the steer-
ing 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
targeted changes to the steering angle pro-
vided by the driver and thus stabilize the
vehicle before the driver intervenes. This
stabilizing intervention is simultaneously
deactivated when DSC is switched off,
refer to page
77 .
Malfunction
The fixed warning lamp lights up.
The active steering is no longer
operational. In the low speed range,
greater steering wheel movement is neces-
sary. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply
interruption, the system must be activated
with initialization.
Initializing system
1. Start the engine
2. With the vehicle stationary, turn the
steering wheel from the straight-ahead
position to the left as far as it will go and
then back to the straight-ahead position
3. Switch off the engine.
When you start the engine again, all the
functions of the active steering are avail-
able once again.
