Technology for driving comfort and safety
82 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 person without luggage:
approx. 155 miles/250 km
>With a medium load:
1 person, cargo area full, or 2 people
without luggage:
approx. 90 miles/150 km
>With a full load:
2 people, 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
TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.
Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
TPM takes into account that tire pressures
change while the vehicle is being driven. The
tire pressures do not need to be corrected
unless the TPM instructs you to do so by means
of color indicators.

Green
The tire inflation pressure corresponds to the
established target value.
"TPM active" appears on the Control Display.
One wheel yellow
There is a flat tire or substantial loss of tire pres-
sure in the indicated tire. A message appears on
the Control Display.
All wheels yellow
There is a flat tire or substantial loss of tire pres-
sure in several tires. A message appears on the
Control Display.
Gray
The system cannot detect a puncture.
Possible reasons for this:
>TPM is being reset
>Temporary malfunction caused by systems
or devices using the same radio frequency
>Malfunction
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
1. Press the button
The start menu is opened.
2."Vehicle Info"
3."Vehicle status"
4."Reset TPM"5.Start the engine, but do not start driving.
6.Start the initialization using "Reset TPM".
7.Start to drive.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The system reset is
completed during your drive, and can be inter-
rupted at any time. When driving resumes, the
reset is continued automatically. On the Control
Display, the tires are shown in green and "TPM
active" is displayed again.
If a flat tire is detected while the system is
resetting and determining the inflation
pressures, all tires on the Control Display are
displayed in yellow. The message "Low tire!" is
shown.<
Message for low tire inflation pressure
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds. There is a flat tire or substan-
tial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the car is not equipped with run-flat
tires, refer to page199, the standard
equipment by design, do not continue driv-
ing. Otherwise, a severe accident could
result after a tire puncture if you continue
driving.<
2.In the event of complete pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:

Route criteria
General information
You can influence the calculated route by
choosing certain route criteria. You can change
the route criteria as often as you like during des-
tination entry or during destination guidance.
The route is planned according to fixed rules.
The type of road is taken into account, e.g.,
whether it is a highway or a winding road. As a
result, the routes recommended by the naviga-
tion system may not always be the same ones
that you would choose based on personal expe-
rience.The settings are stored for the remote control
currently in use.
