Standard tires
1.If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
2.Replace the damaged wheel or wheels,
refer to Changing wheels on page215.
In contrast to a compact wheel, a spare wheel is
equipped with the necessary TPM electronics
and also monitored after mounting and after
resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Run-flat tires*
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 vehicle is not equipped with run-
flat tires, refer to page201, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<
2.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 guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, luggage compartment or
cargo area full, or 4 persons without
luggage:
approx. 95 miles/150 km
>With a full load:
from 4 persons, luggage compartment
or cargo area full:
approx. 30 miles/50 km
Drive reservedly 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 vibrations or loud noises occur while the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact your BMW
center.<
Malfunction
The yellow warning light flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:
>In case of a malfunction;
have the system checked.
>If a wheels is mounted without TPM elec-
tronics
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page87.

Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. The active steering is no longer
operational. At low speeds, greater steering
wheel movements are required, whereas at
higher speeds, the vehicle reacts more sen-
sitively to steering wheel movements. The
stability-promoting intervention can also be
deactivated. Proceed cautiously and drive
defensively. Have the system checked.

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page45.<
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. Do not attempt to
remove the airbag retention system from the
vehicle. Do not modify or tamper with either the
wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, the doors and the roof pillars
along with the sides of the headliner. Do not
attempt to remove or dismantle the steering
wheel. Do not touch the individual components
immediately after the system has been trig-
gered, 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 BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, 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 airbag on the front passenger side are acti-
vated or deactivated accordingly by the system.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
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, observe the safety infor-
mation and handling instructions under Trans-
porting children safely refer to page54.
The front and side airbag on the front passen-
ger side can be deactivated for teenagers and
adults in certain seat positions; then the indica-
tor lamp for the front passenger airbags lights
up. In these cases, change the seat position so
that the front passenger airbags are activated
and the indicator lamp goes out. If the desired
status cannot be produced by changing the
seat position, transport the corresponding per-
son on the rear seat. Do not fit seat covers, seat
cushion padding, ball mats or other items onto
the front passenger seat unless they are specif-
ically 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 airbag 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 system intended for the
purpose is properly detected on the seat.
The front and side airbag on the front pas-
senger side are not activated.
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front and side airbag on the front pas-
senger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbag 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.<
Head-Up Display*
The concept
With the Head-Up Display important informa-
tion is projected into the driver's field of view,
e.g. navigation instructions. This enables you to
take in this information without looking away
from the road.
Switching on/off

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 center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.

BMW Night Vision*
The concept
BMW Night Vision is a driver assistance system
that is designed to provide enhanced vision for
certain objects at night. This can be especially
helpful for detecting people and larger animals.
When objects are detected, the driver may be
able to take appropriate action sooner. For
example, the driver may identify and detect the
presence of persons or animals in the road
ahead or off to the sides and can be more alert,
slow down or stop, blow the horn etc. The driver
can decide which actions are appropriate and
then react accordingly.
A certain area in front of the vehicle is viewed by
an infrared camera and a generated image is
shown on the Control Display. The resulting
thermal image shows the relative heat radiation
of the objects present in the camera's field of
view. Warmer objects appear brighter and
cooler objects appear darker. Contrast is
dependent on the temperature difference
between the objects and the background and
on the amount of heat radiation of the object
itself. As a result, it is quite possible that a per-
son is not continually recognizable as a person
in shape, since the thermal radiation can be
affected by different clothing which blocks heat
loss. Objects with little temperature difference
to the surrounding area, or little heat radiation
are less noticeable, for example in cold weather.Any improvement in detection depends on
many factors such as the object size and tem-
perature compared to the surroundings, or
other nearby objects, the visual recognition
skills of the driver, weather conditions, and
other factors.
Driving hints
With the system active, periodically but briefly,
glance at the thermal image on the Control Dis-
play to notice objects that could be people or
larger animals. The glance should be similar to
glancing at the rear view mirror. Do not stare at
the image for long periods while driving, as this
will remove attention from the road. If you notice
an object of interest ahead, be prepared to slow
down or stop, blow the horn, or take other
appropriate action.
System limits
The system is designed to supplement but not
replace forward vision through the windshield.
The driver is responsible for safe driving at
night. BMW Night Vision is not designed to be
used as a continuous viewing window for driv-
ing at night.
No system, no matter how sophisticated, can
operate without limitations. BMW Night Vision
operation is subject to physical and environ-
mental limitations that will reduce the ability of
the system to detect and display a clear thermal
image. Some of the situations in which these
limitations can occur are:
>on steep hilltops or depressions and in tight
curves
>in tunnels, as the contrast is inherently low
>when the camera lens is dirty

>in dense fog, heavy rain or snowfall
>when displaying very hot objects such as
transformers, car exhausts etc.
>when the image briefly freezes during nor-
mal system adjustment.
BMW Night Vision's potential benefits
can be limited by the driving style of the
driver, the size and relative temperature of the
detected objects, dirt or contamination on the
camera lens, adverse weather like snow, rain or
fog, and other factors not mentioned here. It will
always be the driver's responsibility to drive at a
speed and in a manner that recognizes potential
hazards and adjust accordingly.
BMW Night Vision is not a substitute or replace-
ment for driver responsibility or for accommo-
dating the visibility conditions and the traffic sit-
uation. The forward view illuminated by the
headlamps must always be the basis for making
safe driving decisions, otherwise a safety risk
will result.<
Activating BMW Night Vision
1.Turn the light switch to position2 or3, refer
to page101.
2.With low beams switched on:
>Press the button. Depending on the
vehicle's equipment, the location of the
button may differ somewhat.
>Press one of the programmable buttons
on the steering wheel, refer to page53.
The image will be displayed on the Control Dis-
play after a few seconds. Depending on the last
mode selected, either the normal or full screen
image will be displayed.Due to the system's need to adjust periodically,
a still image is displayed at certain intervals for
fractions of a second. This is normal and not an
indication of a problem.
To prevent driving without headlamps, at a
speed of more than approx. 3 mph/5 km/h and
when dark, the thermal image on the Control
Display is only shown when the low beams are
on.
Deactivating BMW Night Vision
>Press the button.
>Press the button on the steering wheel.
>Press the button.
>Via iDrive", refer to Selecting settings.

Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking. For lighting on one
side for parking as an additional feature, refer to
page102.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, as otherwise it may no longer be
possible to start the engine.<
Low beams
The low beams light up in switch position2 only
with the engine running. Otherwise the parking
lamps are lit.
Automatic headlamp control*
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol is
illuminated when the low beams are on.When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
If desired, the light switch can be left in the
position3. The exterior lighting is automatically
switched off after switching off the vehicle.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You can set the duration or deactivate the func-
tion via iDrive.
