Protect the remote control against unau-
thorized use by handing over only the
spare key, for example when using hotel valet
parking.<
For additional details on the alarm system, refer
to page22.
Because any persons or animals left unat-
tended in a parked vehicle could lock the
doors from the inside, you should always keep
the remote control with you; this precaution
ensures that you will remain able to unlock the
vehicle from the outside at all times.<
Unlocking
Press the button.
Press the button once to unlock the driver's
door only; press a second time to unlock all
remaining doors as well as the tailgate and the
fuel filler door.

Press the button.
If you desire, the vehicle locks automati-
cally if no door or lid is opened after
unlocking. You may have this function set on a
vehicle-specific basis if you wish.<
As confirmation for the fact that the vehicle is
properly locked, the hazard warning flashers
light up.
If you wish, you can have this special fea-
ture deactivated on vehicles without an
alarm system.<

Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood, or the tailgate is
opened.
>To movements inside the vehicle: interior
motion sensor, refer to Tilt alarm sensor
and interior motion sensor.
>To changes in the vehicle tilt angle such as
occur during attempts to steal the wheels or
tow the vehicle.
>To interruptions in battery voltage.The system responds to unauthorized vehicle
entry and attempted theft by simultaneously
activating:
>The acoustic alarm for approx. 30 seconds.
>The hazard warning flashers for approx.
5minutes.
>The high beams, which flash on and off in
the same rhythm.
Arming and disarming alarm system
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
If the alarm system has been properly armed,
the hazard warning flashers light up once.
You can have different acknowledgment
signals set to confirm arming and disarm-
ing.<
You can also open the tailgate with the system
armed using the button on the remote con-
trol, refer to page17. When you close the tail-
gate, the system is rearmed.
Switching off alarm
>Unlock the vehicle using the remote control,
refer to page17.
or
>Turn the ignition key to position 1.
Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.

>The indicator lamp flashes when the vehicle
is locked: door(s) or tailgate are not com-
pletely closed. Even if you do not close the
alerted area, the system begins to monitor
the remaining areas, and the indicator lamp
flashes continuously after 10 seconds.
However, the interior motion sensor is not
activated.
>The indicator lamp goes out when the vehi-
cle is unlocked: no manipulation or
attempted intrusions have been detected in
the period since the system was armed.
>The indicator lamp flashes for 10 seconds
after the vehicle is unlocked: an attempted
entry has been detected in the period since
the system was armed.
Following triggering of an alarm, the indicator
lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. in case of an attempted
wheel theft or towing.
Interior motion sensor
In order for the interior motion sensor to func-
tion properly, the windows and panorama glass
sunroof must be completely closed.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In stacking garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote control
again directly after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the next time the vehicle is unlocked and subse-
quently locked again.
If you wish, the tilt alarm sensor and inte-
rior motion sensor are permanently
switched off. You can have this set at your
BMW Sports Activity Vehicle Center.<
If you interrupt the convenience closing of
the windows and panorama glass sunroof
within the first 10 seconds and then reinitiate
the action, this will unintentionally switch off the
tilt alarm sensor and interior motion sensor.
If this has occurred, the system must be dis-
armed and then rearmed.<

Driving
38 To use the automatic function again, move the
selector lever to the right into position D.
Malfunction
The warning lamp lights up. A malfunc-
tion has occurred in the transmission
system. Avoid heavy loads.
While it will still remain possible to move the
selector lever to any desired position, the trans-
mission will revert to its default mode with only
a limited number of forward gears.
Have the system checked as soon as possible.

Rain sensor*
The rain sensor automatically controls wiper
operation as a function of the rain intensity. It is
positioned on the windshield, directly in front of
the inside rearview mirror.
Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
ired wiper activation.<
Activating
As of ignition key position 1 move the lever to
position1. The wipers travel once across the
windshield, regardless of the weather condi-
tions.
You can leave the lever permanently in posi-
tion 1 and then only need to activate the rain
sensor as of ignition key position 1. To do so:
>Briefly turn the serrated dial 5 or
>clean the windshield 1, refer to next section
Adjusting sensitivity
Turn the serrated dial 5.
Deactivating
Switch lever to position 0.
Normal wiper speed
The system switches automatically to intermit-
tent mode when the vehicle is not moving, not
on vehicles with rain sensor.
Fast wipe
The wipers operate at normal speed when the
vehicle is not moving, not on vehicles with rain
sensor.

Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could be
obscured. To avoid freezing, use a washer fluid
antifreeze, refer to page90. Do not use the
washers when the reservoir is empty. This
could cause damage to the washer pump.<
Cleaning windshield
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
The windshield washer nozzles are automati-
cally heated as of ignition key position 2.
Cleaning headlamps*
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Rear window wiper
Rear window wiper in intermittent mode. When
reverse gear is engaged, the wiper operates
continuously.
You can also program the interval:
1.Briefly move the wiper lever from position 0
to position 2.
2.Wait for desired interval; maximum of
30 seconds.

Technology for comfort, convenience and
safety
PDC Park Distance Control*
The concept
PDC provides extra safety and convenience
during parking maneuvers. Signal tones indi-
cate the current distance to an object behind or
in front of your vehicle. Four ultrasonic sensors
in both the bumpers monitor the distance to the
nearest object.
The front and rear sensors on the corners have
a range of approx. 2 ft/60 cm. The two rear mid-
dle sensors have a range of approx. 5 ft/1.50 m
and the two front middle sensors of approx.
2.6 ft/80 cm.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching objects too fast, otherwise
the system may give warning of physical obsta-
cles too late.<
If you tow a trailer, the rear sensors cannot take
any practical measurements. Therefore, they
do not switch on.
Automatic mode
In ignition key position 2, the system is auto-
matically activated after approx. one second
each time you shift into reverse or move the
selector-lever into position R. Wait for this short
time span before moving. The system switches
off when you shift out of reverse.
You can have a signal tone programmed
into the system to verify that the PDC is
active.<
Manual mode
In ignition key position 2, press the button; the
indicator lamp lights up.
Deactivating manual mode
Press the button again; the indicator lamp goes
out.
After driving a distance of more than approx.
160 ft/50 m or exceeding a speed of approx.
20 mph/30 km/h, the system switches off and
the indicator lamp goes out. You can reactivate
the system manually as needed.
Signal tones
The distance to an object behind the vehicle is
signaled, in accordance with the position, by an
intermittent tone from a speaker in the rear.
The distance to an object in front of the vehicle
is signaled by an intermittent tone from a loud-
speaker beneath the instrument cluster.
As the distance between vehicle and object
decreases, the intervals between the tones
become shorter. The signal tone becomes con-
tinuous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The signal tone is canceled after approx. 3 sec-
onds when the distance to an object remains
constant during this time, if you are moving par-
allel to a wall, for instance.

Malfunction
The indicator lamp in the button flashes and a
short continuous tone sounds. PDC is malfunc-
tioning. Switch off PDC. Have the system
checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects etc. Low objects
already displayed, e.g. a curb, can also disap-
pear from the detection area of the sensors
again before a continuous tone sounds.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Keep the sensors clean and free of ice or
snow in order to ensure that they will con-
tinue to operate effectively.
Do not apply high pressure spray to the sensors
for a prolonged period of time. Keep the spray at
least 4 in/10 cm away from the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during full braking. This results in an
increase in the active safety.
ABS is operational every time you start the
engine. Safe braking, refer to page73.
EBV Electronic brake-force
distribution
EBV controls the brake system's application
pressure in the rear wheels to ensure stable
deceleration.
DBC Dynamic Brake Control
When the brake pedal is depressed quickly, this
system automatically generates a maximal
braking force distribution and thus helps keep
the braking distance to a minimum during full
braking. This system exploits all of the benefits
provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the brake application. DBC is
deactivated when you release the brake pedal.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when
starting off and accelerating. DSC also detects
unstable driving conditions, such as a fishtailing
of the vehicle's rear end or the sliding of the
vehicle on its front wheels. In these circum-
stances, DSC helps keep the vehicle on a safe
path, within physical limits, by reducing engine
output and by applying the brakes in individual
wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
When the indicator lamp flashes:
DSC is controlling the drive and braking forces.
When the indicator lamp stays lit:
DSC has been switched off with the button.

culates the air currently within the vehicle.
During AUC operation, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>Indicator lamps off: outside air flows into the
vehicle.
>Left indicator lamp on, AUC mode: the sys-
tem recognizes pollutants in the outside air
and blocks the flow of air when necessary.
The system then recirculates the air cur-
rently within the vehicle. Depending on the
air quality, the automatic system then
switches back and forth between outside air
supply and recirculation of the air within the
vehicle.
>Right-hand indicator lamp on: the outside
air supply into the vehicle is shut off contin-
uously. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. The recirculated-air mode should not
be used over a sustained period of time, other-
wise the air quality inside the vehicle will deteri-
orate.<
Rear window defroster
When the rear window defroster is
activated, the indicator lamp
comes on. The rear window
defroster switches off automatically.
You can have your vehicle set so that the
rear window defroster switches on auto-
matically. It is then switched on at outside tem-
peratures of less than approx. +397/+46
within 5 minutes of the engine start.<
Ventilation
The air vents for the upper body area can be
adjusted:
1Serrated dials
Serrated dials for opening and closing the
vent outlets through an infinitely-variable
range.
2Levers
Selector levers for airflow direction.
3Serrated dial
Use this serrated dial to adjust the amount
of cool air that is added to the airflow
emerging from the vent outlets for the
upper body.
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance, if the interior has
become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter/activated-charcoal filter*
The built-in microfilter removes dust and pollen
from the incoming air. The activated-charcoal
filter provides additional protection by filtering
gaseous pollutants from the outside air. This
combined filter is replaced when maintenance
is performed by your BMW Sports Activity Vehi-
cle Center. A substantial reduction in air supply
indicates that the filter should be replaced
before normal maintenance.

Hot exhaust system
As in all vehicles equipped with a catalytic
converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking take care to avoid pos-
sible contact between the hot exhaust system
and any highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead to
a fire, resulting in serious personal injury and
property damage.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. portable
phones, in the interior of the vehicle without a
direct connection to an outside antenna. Other-
wise the vehicle electronics and mobile com-
munications device can affect each other. In
addition, there is no assurance that the radia-
tion which results during transmission will be
dissipated from the vehicle interior.<
Inside rearview mirror, automatically
dimming*

The inside rearview mirror contains two photo-
cells that control the automatic dimming func-
tion. One is integrated into the mirror glass, the
other is located on the back of the mirror.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of stickers on the windshield
in front of the mirror, either.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page28, as
otherwise they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor as otherwise dam-
age could result from undesired wiper activa-
tion, refer to page39.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed. Otherwise, the vehicle's
engine, the electrical systems and the trans-
mission may be damaged.<
Use handbrake on inclines
Do not hold the vehicle in place on slopes
by slipping or riding the clutch, use the
handbrake instead. Otherwise greater clutch
wear will result.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. The best way to brake is to apply
maximum pressure to the brake pedal during
emergency: panic braking. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
