5. Drive off.
Initialisation completes while the car is on
the move, without any feedback.
Indication of a flat tyre
The warning light shows red. In addi-
tion, an acoustic signal is emitted.
There is a flat tyre or substantial loss
of tyre pressure.
1. Carefully reduce your speed to no more
than 80 km/h (50 mph). Avoid violent or
sudden braking and steering manoeuvres.
Do not exceed a speed of 80 km/h (50 mph)
after this.
If the car is not fitted with run-flat
tyres, see page 97, the standard
equipment by design, do not continue driv-
ing. Any attempt to drive on after a puncture
can result in a severe
2. Check the pressures in all four tyres at the
next opportunity.
If all four tyres are inflated to the cor-
rect pressures, the Run Flat Indicator
might not have been initialised. In this case
initialise the system.<
3. If a tyre is completely deflated, you can esti-
mate how far you will be able to drive using
the following guidelines:
> With low loads:
1 to 2 persons without luggage:
approx. 250 km (155 miles)
> With moderate loads:
2 persons, luggage compartment full, or

accident.<
4 persons without luggage:
approx. 150 km (90 miles)
>
With a full load:
4 persons or more, luggage compart-
ment full:
approx. 50 km (30 miles)
> When towing a trailer: approx. 50 km
(30 miles)
Drive with caution and do not exceed
80 km/h (50 mph). If there is a loss of tyre
pressure, the vehicle's handling properties will
change. These include reduced track stability
during braking, longer braking distances and
altered self-steering properties.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tyre has finally failed. Reduce your
speed and pull over to the side of the road at the
earliest opportunity. Otherwise, parts of the tyre
could come loose and cause an accident. Do
not drive the car any further, and contact BMW
Service.<
Malfunction
The indicator light shows yellow. The
Run Flat Indicator is malfunctioning
or has failed. Have the system
checked as soon as possible.
Active steering*
The principle
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels, depending on the speed at
which you are driving.
At lower speeds, e.g. in the city or while parking,
the turning angle is increased, i.e. smaller steer-
ing wheel movements and less effort are
required to turn the wheels. At higher speeds, in
contrast, the turning angle is increasingly
reduced. Your BMW's handling is thus
improved across all speed ranges.
In critical situations, the system can correct the
wheel turning angle resulting from the driver's
