trol Display. Initialization is then completed

while the car is in motion.

Indication of a flat tire

The warning lamps come on in yellow

and red. A message appears on the

Control Display. In addition, an

acoustic signal sounds. There is a flat

tire or substantial loss of tire pressure.

1. Cautiously reduce speed to below 50 mph

or 80 km/h. Avoid sudden braking and

steering maneuvers. Do not exceed a speed

of 50 mph or 80 km/h.

If the car is not equipped with Run-

Flat Tires, refer to page 196, the stan-

dard equipment by design, do not continue

driving. Otherwise a severe accident could

result after a tire puncture.<

2. At the next opportunity, check the air pres-

sure in all four tires.

If all four tires are inflated to the cor-

rect pressures, the Flat Tire Monitor

might not have been initialized. The system

must then be initialized.<

3. In the event of complete tire pressure loss,

0 psi/0 kPa, you can estimate the possible

distance for continued driving on the basis

of the following guidelines:

> 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. 90 miles/150 km

> With a full load:

4 or more persons, luggage compart-

ment full:

approx. 30 miles/50 km

Drive cautiously and do not exceed a

speed of 50 mph or 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 vibration or loud noises occur during

the journey, this may be an indication that the

damaged tire has finally failed. Reduce your

speed and pull over to the side of the road at the

earliest opportunity. Otherwise, parts of the tire

could come loose and cause an accident. Do

not continue driving. Contact your BMW Cen-

ter.<

Malfunction

The warning lamps come on in yel-

low. A message appears on the Con-

trol Display. The Flat Tire Monitor has

a malfunction or has failed. Have the

system checked as soon as possible.

Active steering*

The concept

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.

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, and less effort is required to turn the

wheels. 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 85.

Malfunction

The warning lamps come on. Active

steering is no longer operational. At

low speeds, greater steering wheel

movements are required, whereas at

higher speeds the vehicle reacts more sensi-

tively to steering wheel movements. Drive cau-
