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.<

Cleaning camera
The function of the camera may be affected by
heavy rain and fog, dirt, snow or ice on the lens.
When this occurs, the displayed image on the
Control Display may become gray.To minimize icing, the camera lens is automati-
cally heated. However, it may be necessary to
clean the camera lens manually under severe
weather conditions. When doing so, cautiously
remove any debris, ice or snow. To avoid dam-
age to the lens, do not use sharp or abrasive
instruments to clean ice, snow, or dirt off the
lens.
When the windshield is cleaned with the head-
lamps on, the camera lens area is automatically
sprayed as well. Refer to page68.
Leaving lane warning*
The concept
This system warns you from a speed of approx.
40 mph/70 km/h when the vehicle is leaving the
lane you are currently in on roads with lane limit
lines. You feel this due to a slight vibration of the
steering wheel.
The system does not warn you if you signal
before leaving the lane.
It is best to use the system on well-developed
roads and freeways.
Switching on/off
Press the button on the steering wheel.
>The two lines1 indicate that the system is
activated.
>The two arrows2 mean that the system has
detected one or two lane limit lines from a
speed of approx. 40 mph/70 km/h and
warns accordingly.

If you activate the system below a speed of
approx. 40 mph/70 km/h, a message will appear
stating that the system is not active until this
speed is reached.
A warning will be canceled:
>after approx. 3 seconds
>if you return to your lane
>if you brake heavily
>if you signal
System limits
The leaving lane warning cannot serve as
a substitute for your personal judgment in
determining the course of the road.
If the system issues a warning, do not move the
steering wheel with unnecessary severity, as
otherwise you could loose control of the vehi-
cle.<
The function of the system may be limited in the
following example situations:
>in heavy fog, rain or snowfall
>with worn-away, poorly visible limit lines, or
lines that run together or apart or are
unclear, e.g. in road construction areas
>when limit lines are covered by snow, ice,
dirt or a great deal of water
>in tight curves or on narrow roads
>when limit lines are not white
>when limit lines are covered by objects
>when driving up close behind a vehicle driv-
ing ahead
>with bright counter light
>when the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values worsen. Have the
vehicle checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Event Data Recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can
be transmitted or recorded to enable corre-
sponding services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.

Emergency request
Conditions for an emergency request:
>Full preparation package mobile phone.
With this equipment, an emergency request
is still possible when no mobile phone is
paired in the vehicle.
>BMW Assist is activated.
Activating BMW Assist, refer to page214.
>Radio readiness is activated.
>The BMW Assist system is logged on to a
mobile phone network.
>The emergency request system is opera-
ble.
Once your BMW Assist subscription expires,
the BMW Assist system can be deactivated by
a BMW center without you having to visit a
workshop. Once the BMW Assist system has
been deactivated, emergency requests are not
possible. The BMW Assist system can be reac-
tivated by a BMW center after signing a new
contract.
Initiating an emergency request
1.Briefly press protective cover to open.
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
2.Press the SOS button for at least
2seconds.The LED in the button lights up. As soon as the
voice connection to the BMW Assist Response
Center has been established, the LED flashes.
Even if you are unable to answer, the BMW
Assist Response Center can take further steps
to help you under certain conditions.
If conditions allow, remain in the vehicle until
the connection has been established. You will
then be able to provide a detailed description of
the situation.
If the current position of your vehicle can be
determined, it will be transmitted to the BMW
Assist Response Center.
If the LED is flashing but the BMW Assist
Response Center cannot be heard over the
hands-free system, it is possible that the
hands-free system is malfunctioning. You may
still be heard by the BMW Assist Response
Center, however.
Under certain conditions, an emergency
request is automatically initiated immediately
after a severe accident. The automatic collision
notification is not affected by the button being
pressed.
For technical reasons, the emergency request
cannot be guaranteed under unfavorable condi-
tions.
You can also use other services of
BMW Assist with this button, refer to

Being towed
Make sure that the ignition is switched on,
refer to page61, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right. When
the engine is stopped, there is no power assist. This then requires increased effort for braking
and steering. Active steering is deactivated and
larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Automatic and sport automatic
transmission
Before towing, manually release the
transmission lock, even if there is no mal-
function in the transmission. Otherwise there is
a risk that the transmission lock will automati-
cally be engaged during towing.<
Manually unlocking and locking transmission
lock, refer to page65.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
