Function requirements
The system must have been initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Initialize the system after every correction of the
tire inflation pressure and after every tire or
wheel change.
System limits
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.
whether or not the FTM is active.

2."Vehicle status"
3."Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains
* or with the compact wheel*.

The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.<
Indication of a flat tire
The warning lamp lights up red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or a major loss in tire
inflation pressure.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
If the vehicle is not equipped with run-flat
tires as provided at the factory, refer to
page249, do not continue driving. Continuing
to drive with a flat tire could cause severe acci-
dents.<

When driving with a damaged tire:
1.Avoid sudden braking and steering maneu-
vers.
2.Do not exceed a speed of 50 mph/80 km/h.
If the defective tire continues to lose pres-
sure, its position will be indicated to you on
the Control Display.
3.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
Possible driving distance with complete loss of
tire inflation pressure.
>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. 95 miles/150 km
>With a full load:
4 or more persons, cargo area full:
Approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g.
reduced lane stability during braking, a longer
braking distance and altered self-steering prop-
erties.<
Vibrations or loud noises while driving can
indicate complete failure of the tire.
Reduce your speed and stop; otherwise, pieces
of the tire could come loose and cause an acci-
dent. Do not continue driving, and contact your
BMW Sports Activity Vehicle Center. The concept
Monitoring of the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Function requirements
The system must have been reset while the
inflation pressure was correct; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres-
sures.
The system is inactive and cannot indicate a flat
tire:

Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If your vehi-
cle has tires of a different size than the size indi-
cated on the vehicle placard or tire inflation
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
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly underinflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
observe the adjustment instructions on
page42.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
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 are deliberately not triggered in
every impact situation, e.g. less severe acci-
dents 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.
Keep the instrument cluster and window in the
region of the passenger seat free of foreign
materials, i.e. do not cover them with adhesive
film or covers and do not attach mounts, e.g. for
a navigation device or mobile phone to them.
Do not install cosmetic covers, seat cushions,
or other items on the front seats that are not
especially approved for seats with integrated
side airbags. Do not hang articles of clothing
such as jackets over the backrests.Do not attempt to remove the airbag restraint
system from the vehicle. Do not modify or
tamper with either the wiring or the individual
components in the airbag system. This includes
the upholstery in the center of the steering
wheel, on the instrument cluster, the doors, and
the roof pillars as well as the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel. Do not touch the individual
components immediately 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 Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and has
the required explosives licenses. Otherwise
unprofessional attempts to service the system
could lead to failure in an emergency or undes-
ired airbag triggering, either of which could
result in personal injury.<
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
The current status of the front passenger
airbag, i.e. deactivated or activated, is

Technology for comfort, convenience and safety
108 indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<
Before transporting a child on the front
passenger seat, read the safety informa-
tion and follow the instructions under Trans-
porting children safely, refer to page54.
When teenagers and adults assume certain sit-
ting positions, this can cause the front and side
airbags to deactivate. The indicator lamp for the
front passenger airbags lights up when this
occurs. In these cases, change the sitting posi-
tion so that the front passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired status cannot be produced by changing
the sitting position, transport the correspond-
ing person on the rear seat. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically recommended by BMW. Do not
lay objects under the seat which could press
against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured.<
Operating state of front passenger
airbags
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
>The indicator lamp lights up when a child in
a child restraint device intended for the pur-pose is properly detected on the seat.
The front and side airbags on the front pas-
senger side are not activated.
Most child's seats are detected by the
system. Especially the child's seats
required by NHTSA at the time the vehicle
is manufactured. After installing a child's
seat, make sure that the indicator lamp for
the front passenger airbags lights up. This
indicates that the child's seat has been
detected and the front passenger airbags
are not activated.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
front and side airbags on the front passen-
ger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags on the
front passenger side are not activated.
Operational readiness of airbag system
From radio readiness, refer to page58, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up from radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction, otherwise
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<

Notes
The visibility of the displays in the Head-up Dis-
play is influenced by:
>Sunglasses with certain polarization filters
>Certain sitting positions
>Objects on the cover of the Head-up Dis-
play
>Wet road surface and unfavorable lighting
conditions
If the image is distorted, have the basic setting
checked at a BMW Sports Activity Vehicle Cen-
ter.
Special windshield
The windshield is part of the system. The shape
of the windshield complies with the require-
ments of the Head-up Display to enable a pre-
cise display. A film in the windshield prevents
the double images from being displayed.
Windshield replacement should be carried out
by a BMW Sports Activity Vehicle Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel.
Care instructions
Important information on this topic is provided
on page260.
Only clean the cover of the Head-up Dis-
play with a soft, lint-free cloth or with a
display cleaning cloth, otherwise damage may
result.<

A congenial climate
The AUTO program offers the optimum air dis-
tribution and air volume for virtually all condi-
tions, refer to AUTO program below. Now you
only need to select an interior temperature
comfortable for you.
The following sections contain more detailed
information on the available setting options.
Most settings are stored for the remote control
currently in use, also refer to Personal Profile
settings on page26.AUTO program
The AUTO program handles the
adjustment of air volume and air
distribution to the windshield and
side windows, in the direction of
the upper body and in the footwell.
It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program in such
a way that window condensation is prevented
as much as possible.

Intensity of AUTO program
You can adjust the intensity of the AUTO pro-
gram by repeatedly pressing the AUTO button.
The selected intensity, SOFT, MEDIUM or
INTENSIVE, appears on the display of the auto-
matic climate control.
Temperature
Set the desired temperature indi-
vidually on the driver's and front
passenger side.
The automatic climate control
adjusts this temperature as quickly as possible
at any time of year, if necessary with the maxi-
mum cooling or heating capacity, and then
keeps it constant.
In the highest setting you activate the maximum
heating capacity, regardless of the outside tem-
perature. And in the lowest setting, the maxi-
mum cooling capacity.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to adjust the set temperature.<
Adapting Ventilation temperature
This function can be used to adjust the temper-
ature of the air to the upper body region, refer to
page116, separately for the driver and front
passenger.
Use the controller on the Control Display to
adjust the ventilation temperature.
To accomplish this, the access the Ventilation
temperature setting manually via the buttons
for air distribution, refer to page117, or via
iDrive.

3Air to footwell
Pressing the AUTO button cancels the
manual air distribution settings.<
The automatic mode for the air volume remains
effective with manual air distribution.
Switching cooling function on and off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
This function is only available when the engine
is running.
The cooling function helps to avoid condensa-
tion on the window surfaces or to quickly
remove them.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati-
cally with the AUTO program.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible at an outside
temperature above approx. 327/
06 and with the engine running.
The automatic climate control switches into the
recirculated-air mode at the lowest tempera-
ture. The maximum air volume flows out of the air vents for the upper body. Therefore, open
these vents for maximum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system
then recirculates the air currently within the
vehicle. During AUC operation, a sensor
detects pollutants in the outside air and con-
trols the shut-off automatically.
By pressing the button repeatedly, you can
request three operating modes:
>LED off: outside air flows in continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
>Right LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirculated-air mode and
increase the air volume if necessary.
The recirculated-air mode should not be used
without interruption over an extended period of
time, as the air quality inside the vehicle deteri-
orates continuously.<
Residual heat
The heat stored in the engine is used to heat the
passenger compartment, e.g. while stopped at
a school to pick up a child.
Switching on
Pressing the right side switches on
the residual heat utilization when
the following conditions are met:
>Up to 15 minutes after switching off the
engine
>With the engine at operating temperature
>With sufficient battery voltage
>At an outside temperature below 777/
