reset is continued automatically. On the Control
Display, the wheels are shown in green and
"Status: TPM active" is displayed again.
If a flat tire is detected while the system is
resetting and determining the inflation
pressures, all wheels 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.Reduce your speed and carefully stop the
car. Avoid sudden braking and steering
maneuvers.
2.If all four wheels are shown in yellow, iden-
tify the damaged wheel on the vehicle.
3.Repair the flat tire with the M Mobility Sys-
tem, refer to page226.
Have the tire replaced by a BMW center or a
workshop that is informed in the handling of
TPM and that works according to BMW repair
procedures with correspondingly trained per-
sonnel.
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 wheels 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.
Message for unsuccessful system
reset
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. The system is not reset after a
tire has been changed, for example.
Check the tire inflation pressure and reset the
system, refer to page87.
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 inflation 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, you 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 underinflated tire causes the
tire to overheat and can 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 driver’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.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a

Technology for driving comfort and safety
90 head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attach
seat covers, cushions or other objects not spe-
cifically approved for seats with integral side air-
bags to the front seats. Do not hang items of
clothing such as coats or jackets over the back-
rests. Do not attempt to remove the airbag
retention system from the vehicle. Do not mod-
ify the individual components of the system or
its wiring in any way. This includes the uphol-
stered covers on the steering wheel, instrument
panel, seats and roof posts, as well as the sides
of the roof lining. 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, removal 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 that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impression in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passenger are activated or
deactivated by the system accordingly.The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or
activated, refer to Status of front passenger air-
bags below.<
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, refer to page51.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indicator lamp for the front
passenger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the front passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, transport the rele-
vant passenger on a rear seat. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the front passenger seat unless
they are specifically recommended by BMW.
Do not place any items under the seat which
could press against the seat from below. Other-
wise a correct analysis of the seat cushion is not
ensured.<
Status of front passenger airbags
The indicator lamp for the front passenger air-
bags shows the functional status of the front
passenger's front and side airbags in accor-
dance with whether and how the front passen-
ger seat is occupied. The indicator lamp shows
whether the front passenger airbags are acti-
vated or deactivated.
>The indicator lamp lights up when a child in
a specially designated child-restraint sys-
tem is detected, as intended, on the seat.

maintenance.
Parked car ventilation
The concept
The parked car ventilation provides ventilation
to the passenger compartment and lowers its
temperature, if necessary.
It is ready for use at any outside temperature
during parked car operation.
The parked car ventilation remains switched on
for 30 minutes. Two different switch-on times
can be preselected. The system can also be
switched on and off directly.
Due to its high power consumption, it should
not be switched on twice in a row without driv-
ing in between to allow the battery to recharge.The air emerges from the air vents for the upper
body area in the instrument panel. The air vents
must therefore be open.
The parked car ventilation system is operated
