2. Repair the puncture, see page 199 .
Run-flat tyres*
1. Carefully reduce your speed to no more
than 80 km/h or 50 mph. Avoid violent or
sudden braking and steering manoeuvres.
Do not exceed a speed of 80 km/h or
50 mph after this.
If the car is not fitted with run-flat
tyres, see page
183 , do not continue
driving. Any attempt to drive on after a
puncture can result in a severe accident.
<
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, approx. 155 miles
> With moderate loads:
2 persons, luggage area full, or 4 per-
sons without luggage:
Approx. 150 km, approx. 90 miles
> With a full load or while towing a trailer:
4 or more persons, luggage area full:
Approx. 50 km, approx. 30 miles
Drive with caution and do not exceed
80 km/h or 50 mph, as otherwise there is
a danger that accidents might occur. 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.
When a trailer is being towed, heavy trailers in
particular can start to snake. For this reason, do
not exceed 60 km/h, approx. 35 mph, as other-
wise there is a danger that accidents might
occur.
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 stop at a suitable location as soon as
possible. Otherwise, parts of the tyre could
come loose, which could result in an accident.
Do not drive the car any further; contact BMW
Service instead.

Status display
The current status of the Run Flat Indicator can
be shown on the Control Display, e.g. whether
the Run Flat Indicator is active.
1. "Vehicle information"
2. "Vehicle status"
3. "Flat Tyre Monitor"
The status is displayed.
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
steering and thus stabilise the vehicle before
the driver takes any action. This stabilising
intervention function is deactivated when DSC
is switched off, see page
72 .
