chnology for

driving comfort

and

safe

Start the engine immediately before pulling
away, but do not drive off yet.

Lightly push button

1 in the turn indicator

lever up or down repeatedly until the corre-
sponding symbol appears in the display
accompanied by the word "RESET".

Press button

2 to confirm your choice of the

Flat Tire Monitor.

Press button

2 for approx. 5 seconds, until

the reading shown below is displayed:

Start driving.
Initialization is completed while the car is on
the move, without any feedback.

Indication of a flat tire

The warning lamps come on in yellow
and red. In addition, an acoustic sig-
nal sounds. There is a flat tire or sub-
stantial loss of tire pressure.

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

130

, the standard

equipment by design, do not continue driv-

ing. Otherwise, a severe accident could
result if you continue driving.

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.

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, cargo area full, or 4 persons
without luggage:
Approx. 90 miles/150 km

With a full load:
4 persons, cargo area full:
Approx. 30 miles/50 km

Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h; otherwise,

there is a risk of an accident. 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 as soon as possible at a
suitable location. Otherwise, parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.

Tire Pressure Monitor TPM*

The concept

RDC monitors the tire inflation pressure in the
four mounted tires during a trip. The system
notifies you if there is a significant loss of pres-
sure in one or more tires.
