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 su bstantial 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. <
iDrive, for operating principle refer to page 16.
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 initializatio n 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 "Sta-
tus: 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 "Tire low!" 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 page 195, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire punc ture 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:
>With a light load:
1 person without luggage:
approx. 155 miles/250 km
> With a medium load:
1 person, cargo bay full, or 2 people
without luggage:
approx. 95 miles/150 km
> With a full load:
2 people, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/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 lo ud 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. Otherw ise parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center. <
Message for unsuccessful system
reset
The warning lamp lights up yellow. A
message will appear on the Control
Display. The system is not reset after
a tire has been changed, for example.
Check the tire inflation pressure and reset the
system, refer to page 83.
Status display
iDrive, for operating pr inciple refer to page16.
1. Press the button
The start menu is opened.
2. "Vehicle Info"
3. "Vehicle status"
4. "TPM"
5. The status is displayed.
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. On the Control Display,
the tires are shown in gray and a message
appears. No punctures can be detected.
This type of message is shown in the following
situations:
> If there is a malfunction
Have the system checked.
> If a wheel without TPM electronics has
been mounted
> If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.
Declaration according to
NHTSA/FMVSS 138
Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire infl ation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, yo u should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underi nflated tire causes the
tire to overheat and ca n lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the dr iver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.

Do not attempt to remove
the airbag retention
system from the vehicle. Do not modify the indi-
vidual components of the system or its wiring in
any way. This includes the upholstered covers
of the steering wheel, the dashboard and the
seats. Do not attempt to remove or dismantle
the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, remo val and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and th at has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesi red airbag activation,
either of which could resu lt in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
The system determines whether the passenger
seat is occupied by meas uring the resistance of
the human body. Front, knee and side airbags
on the passenger side ar e activated or deacti-
vated accordingly.
Make sure that the passenger keeps his
or her feet in the footwell; otherwise, the
passenger airbags may not function properly. <
The indicator lamp above the interior rearview
mirror shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, see page 48.
Malfunction of the automatic
deactivation system
The front, knee and side airbags can also be
deactivated by adolescents and adults sitting in
certain positions; the in dicator lamp for the pas-
senger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the pa ssenger airbags are acti-
vated and the indicator la mp goes out. If the
desired airbag status cannot be achieved by
changing the sitting posi tion, do not transport
the passenger in the vehicle.
To make sure that occupa tion of the seat cush-
ion can be detected correctly:
> Do not attach seat covers, seat cushion
padding, ball mats or other items to the pas-
senger seat unless they are specifically rec-
ommended by BMW.
> Do not place any items under the seat which
could press against the seat from below. <
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front, knee and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
> The indicator lamp lights up when a child
who is properly seated in a child-restraint
system intended for that purpose is
detected on the seat or the seat is empty.
The front, knee and side airbags for the pas-
senger are not activated.
Most child seats are detected by the sys-
tem, especially child seats required by the
NHTSA at the time of vehicle production.
