2. At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
has not been initialized. The system must
then be initialized.<
3. In the event of complete tire pressure loss,
0 psi/0 kPa, or obvious tire damage, you can
estimate the possible distance for contin-
ued driving on the basis of the following
guide values:
> With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
> With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km
> With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations occur while the vehicle is
being driven, this can indicate final failure of the
damaged tire. Reduce speed and stop as soon
as possible. Do not continue driving. Contact
your BMW center.<
Malfunction
The warning lamp lights up yellow and
a message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
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 stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page 78.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speeds, greater steering wheel move-
ments are required, whereas at higher speeds,
the vehicle reacts more sensitively to steering
wheel movements. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Initializing system
1. Start the engine.
2. With the vehicle stationary, turn the steer-
ing 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 func-
tions of the active steering are available once
again.
