100 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. Otherwise unprofessional attempts to
service the system could lead to failure in an
emergency or undesired 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
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 page56.
The front and side airbags on the front passen-
ger side can be deactivated for teenagers and
adults in certain sitting positions; then the indi-
cator lamp for the front passenger airbags lights
up. In these cases, change the sitting position
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 system intended for the
purpose 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 the 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 height is detected on the seat.
The front and side airbags 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 airbags on the
front passenger side are not activated.

Operational readiness of airbag system
From radio readiness, refer to page61, 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.<

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

Technology for comfort, convenience and safety
104 >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 the driver's responsibility to adapt to
visibility and traffic conditions. The forward view
illuminated by the headlamps must always be
the basis for making safe driving decisions, oth-
erwise a safety risk will result.<
Activating BMW Night Vision
1.Turn the light switch to position2 or3, refer
to page107.
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 page54.
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.

3Automatic headlamp control
*, daytime run-
ning lamps
*, welcome lamps, Adaptive
Head Light
* and high-beam assistant*
If you open the driver's door with the ignition
switched off, the exterior lighting is switched off
when the light switch is in position2 or 3. The
daytime running lamps have already been
switched off at the same time as the ignition.
For this reason, switch on the side marker
lamps as needed, switch position1; otherwise,
the vehicle is not lit.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine. It is preferable to
switch on the roadside parking lamps on one
side, refer to page109.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control*
In 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
lights up when the low beams are on. You can
activate the daytime running lamps, refer to
page108. In the above-mentioned situations,
the system then switches to the low beams.
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
*.<
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
low beams manually under these conditions.<
Welcome lamps
If you leave the light switch in position2 or 3
when parking the vehicle, then when you unlock
the vehicle, the parking lamps and interior light-
ing remain illuminated for a brief time.
Activating/deactivating welcome
lamps
iDrive, for operating principle refer to page16.

4.Select "Vehicle / Tires" and press the con-
troller.

Lamps
110 and low beams, reacting to oncoming traffic,
vehicles ahead of you, and sufficiently lit areas,
e.g. in built-up zones.
Manually switching between high
beams and low beams
If you wish or the situation requires, you can
intervene at any time.
>If the high-beam assistant has switched on
the high beams, but you wish to use the low
beams, just switch on the low beams with
the turn signal lever. This deactivates the
high-beam assistant.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>If the high-beam assistant has switched on
the low beams, but you wish to use the high
beams, simply switch on the high beams as
usual. This deactivates the system and it is
up to you to switch back to low beams.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>When the low beams are on, use the head-
lamp flasher as usual.
System limits
The high-beam assistant is designed to
maximize the amount of time that high
beams can be safely used and to quickly switch
back to low beams when traffic approaches.
The system cannot completely replace driver
intervention when unusual conditions are
encountered. For this reason, switch to low
beams when circumstances so dictate. Failure
to do so can pose a safety risk.<
Below are a few examples of situations in which
the system may not react or may only function
to a limited degree, requiring personal interven-
tion:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation
>in sensing road users with poor inherent
illumination such as pedestrians, cyclists,
equestrians, horsedrawn vehicles, railroad or shipping traffic close to the road, and at
deer crossings
>in tight curves, on steep crests or dips, with
cross-traffic, or with partially hidden
oncoming traffic on divided highways
>in poorly illuminated areas and in the pres-
ence of highly reflective signs
>in the low speed range
>when the windshield is fogged up, dirty or
covered with stickers, decals etc. in the area
of the inside rearview mirror
>when the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth slightly moistened with glass
cleaner
Moreover, no system can operate without limi-
tations. High-beam assistant operation is sub-
ject to conditions that may reduce the system's
ability to recognize the difference between
actual vehicle head lamps or tail lamps and, for
example, highly reflective signs, markers, and
streetlights. To be on the safe side, the system
may periodically interpret these situations as
conditions that require low beams. Below are
some of the situations in which premature
switching to low beams can occur:
>approaching large and/or highly reflective
signs
>approaching certain lights, such as drive-
way lighting and porch lights
>approaching certain traffic signals
>approaching large reflective markers
In these situations, the system may interpret
the above conditions as a vehicle ahead requir-
ing a switch to low beams. When the conditions
return to normal, the system will reactivate the
high beams.
The high-beam assistant cannot replace the
driver's responsibility for complying with state
laws on high-beam switching or for adapting to
visibility and traffic conditions.
