▷Do not hang pieces of clothing, such as jack‐
ets, over the backrests.▷Make sure that passengers do not lean their
heads against the side airbag; otherwise, se‐
rious injuries could result if the airbag sud‐
denly deployed.▷Do not remove the airbag restraint system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, cover them or modify
them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system. This
also applies to the covers of the steering
wheel, the dashboard and the seats.◀
In the case of a malfunction, deactivation
and after triggering of the airbags
Do not touch the individual components imme‐
diately after the system has been triggered; oth‐
erwise, there is the danger of burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
your service center or a workshop that has the
necessary authorization for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or un‐
desired triggering of the airbag, either of which
could result in 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 front pas‐
senger seat is occupied by measuring the re‐
sistance of the human body. The front and side
airbags on the front passenger side are acti‐
vated or deactivated accordingly by the system.
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.
Passenger feet in the footwell
Make sure that the front passenger keeps
his or her feet in the footwell; otherwise, the front
passenger airbags may not function properly.◀
Child restraint fixing system in the front
passenger seat
Before transporting a child on the passenger
seat, read the safety and operating instructions
under Transporting children safely, refer to
page 43.◀
Malfunction of the automatic
deactivation system
The front passenger airbags may be deactivated
if adolescents and adults sit in certain positions;
the indicator lamp for the front passenger air‐
bags comes on. In this case, change the 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, do not transport
the passenger in the vehicle.
To make sure that occupation of the seat cush‐
ion can be detected correctly:▷Do not attach seat covers, seat cushion pad‐
ding, ball mats or other items to the passen‐
ger seat unless they are specifically recom‐
mended by BMW.▷Do not place any objects on the front pas‐
senger seat.▷Do not place objects under the seat that
could press against the seat from below.

If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx. 50 miles/
80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service 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.
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flatSeite 77SafetyControls77

Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire
Normal tires1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
The use of tire sealant can damage the TPM
electronics. In this case, have the electron‐
ics checked at the next opportunity and have
them replaced if necessary.

Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended 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 inflation pressure la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly 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 pres‐
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi‐
ciency and tire tread life, and may affect the ve‐
hicle's handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re‐
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres‐
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups 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 in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Brake force display
The concept▷During normal brake application, the brake
lamps light up.▷During heavy brake application, the turn sig‐
nals light up in addition.
The brake force display is not activated if the
turn signal function is switched on.
