Opening and closing: from
outside
Using the remote control
Protect the remote control against unau-
thorized use by handing over only the
spare key, for example when using hotel valet
parking.<
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
1.Press the button.
The driver's door and fuel filler door are
unlocked.
2.Press the button again.
All remaining doors and the liftgate are
unlocked.
Convenience opening mode
Press and hold the button. The windows and
the panorama glass sunroof
* are opened.
If you wish, you can have this special fea-
ture activated/deactivated.<
Engaging locks
Press the button.
If you wish, the vehicle locks automati-
cally if no door or lid is opened after
unlocking. You can have your vehicle set to do
this if you wish.<
As confirmation of 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.<
Switching off tilt alarm sensor* and
interior motion sensor*
Press the button again directly after
locking.
For details, refer to page25.
Switching on interior lamps
Press the button if the vehicle is
locked.
You can also use this function to locate your
vehicle in parking garages etc.
Panic mode*
You can also trigger the alarm system in case of
danger:
Press the button for at least three seconds.
Deactivating alarm: press any button.
Unlocking liftgate
Press the button.
The liftgate will open slightly, regardless of
whether it was previously locked or unlocked.
To avoid damage, make sure there is suf-
ficient space when opening the liftgate.
A previously locked liftgate is also locked again
after closing.
Before and after a drive, make sure that the lift-
gate has not been inadvertently released.<
If so desired, you can have the remote
control system open the liftgate only
when the vehicle is unlocked. You can have
your vehicle set to do this if you wish.<
Malfunction
The remote control may malfunction due to
local radio waves.
Should this occur, use the master key to unlock
and relock the vehicle via the door lock.
If it is no longer possible to lock the vehicle
using the remote control, its battery is dis-
charged. Use this remote control during an
extended drive; this will recharge the battery,
refer to page18.

Closing manually
In the event of an electrical malfunction, you can
move the panorama glass sunroof manually.
1.Pull the cover firmly downward to remove.
2.Insert the Allen wrench from the compart-
ment beneath the cargo area floor, refer to
page103, into the proper opening and turn
the panorama glass sunroof in the desired
direction. The arrow in the illustration indi-
cates the rotation direction for closing the
sunroof.
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood, or the liftgate is
opened.
>To movements inside the vehicle: interior
motion sensor, refer to description below.
>When the car's inclination changes, for
instance if an attempt is made to jack it up
and steal the wheels or to raise it prior to
towing away.
>To interruptions in battery voltage.
The alarm system signals unauthorized manip-
ulations for a short time by:
>Sounding an acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams
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 open the liftgate even when the system
is armed by using the button of the remote
control, refer to page19. When the liftgate is
closed, it is locked again and monitored.
Switching off alarm
>Unlock the vehicle using the remote control,
refer to page19.
>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 after the vehicle
is locked: doors, hood, or liftgate are not
properly 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 approx. 10 sec-
onds. However, the interior motion sensor
is not activated.
>The indicator lamp goes out after unlocking:
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
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 duplex 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 con-
trol again as soon as the vehicle is locked.
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, you can have the tilt alarm
sensor and interior motion sensor perma-
nently switched off. You can have this setting
made at your BMW Sports Activity Vehicle
Center.<

You can set the wipe interval to four stages with
the knurled wheel 5.
In addition, the wipe interval is varied automati-
cally depending on road speed.
Rain sensor*
The rain sensor automatically controls wiper
operation as a function of the rain intensity.
The sensor is mounted on the windshield,
directly in front of the interior 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.<

Technology for comfort, convenience and
safety
PDC Park Distance Control*
The concept
PDC provides extra safety and convenience
during parking maneuvers. Audible signals indi-
cate that you are approaching an object in front
of or behind your vehicle. To measure the dis-
tance, there are four ultrasonic sensors in each
bumper.
An acoustic signal begins to sound when the
front sensors and the rear corner sensors are
within approx. 2 ft/60 cm of an obstacle and
when the rear middle sensors are within approx.
5 ft/1,50 m of an obstacle.
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 are driving with a trailer, the rear sensors
cannot take any meaningful measurements.
Consequently, 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.
You can have a signal tone programmed
into the system to verify that the PDC is
active.<
Activating manual mode
In ignition key position 2, press the button; the
LED lights up.
Deactivating manual mode
Press the button again, the LED goes out.
The system is automatically deactivated once
the vehicle travels approx. 160 ft/50 m or
exceeds a speed of roughly 20 mph/30 km/h;
the LED goes out. You can reactivate the sys-
tem manually as needed.
Signal tones
An intermittent tone from a rear speaker signals
the distance to an object behind the vehicle as
you approach it.
An intermittent tone from a speaker beneath
the dashboard signals the distance to an object
in front of the vehicle as you approach it.
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.
An intermittent tone is interrupted after approx.
3seconds:
>if y o u r e m a in i n f ro n t o f a n o b j e c t t ha t is o n ly
detected by one of the corner sensors
>if you are moving parallel to a wall

Technology for comfort, convenience and safety
48
Malfunction
The LED in the button flashes and a short con-
tinuous tone sounds. PDC is malfunctioning.
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.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
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 come into the
blind spot of the sensors before a continuous
tone sounds. The system may fail to detect
higher obstacles such as ledges.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability even under unfavorable driving
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 page78.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
DBC Dynamic Brake Control
When the brake pedal is depressed quickly, this
system automatically generates a maximum
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.
As long as you want full braking to continue, do
not reduce pressure on the brake.
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. Do not reduce the additional safety mar-
gin again by taking unnecessary 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.

Air conditioner
64 >Left LED on, AUC mode: a sensor detects
pollutants in the outside air. The system
suspends the supply of outside air as
needed and recirculates the air currently
within the vehicle. As soon as the concen-
tration of pollutants in the outside air has
decreased sufficiently, the system switches
automatically back to supplying outside air.
>Right LED on, recirculated-air mode: the
outside air supply into the vehicle is shut off
continuously. 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 and increase the air supply as needed.
The recirculated-air mode should not be used
over a sustained period of time; otherwise, the
air quality inside the vehicle will steadily deteri-
orate.<
Rear window defroster
The rear window heating switches
off automatically after a certain
amount of time.
Ventilation
1Knurled wheels for opening and closing the
air vents through an infinitely variable range
2Levers for changing airflow direction
3Knurled wheel for more or less cool air from
the air vents for the upper body region
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 microfilter removes dust and pollen from
the incoming outside air. The activated-char-
coal filter provides additional protection by fil-
tering gaseous pollutants from the outside air.
This combined filter is replaced when mainte-
nance is performed by your BMW Sports Activ-
ity Vehicle Center. A substantial reduction in
air supply indicates that the filter should be
replaced before normal maintenance.

1.Close all windows and the panorama glass
sunroof.
2.Greatly increase the air supply of the air
conditioning system or automatic climate
control, refer to page60 or63.
Hot exhaust system
High temperatures occur in the exhaust
system of every vehicle. Do not remove
the heat shields installed adjacent to various
sections of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle, and parking, take care to avoid possible
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. mobile
phones, on 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.<
Interior and exterior mirror,
automatically dimming*
Two photocells are used to control the auto-
matically dimming interior and exterior mirrors.
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 sticker to 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 therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page30;
otherwise, they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor; otherwise, damage
could result from undesired wiper activation,
refer to page40.
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.<
The danger of hydroplaning increases as tire
tread depth decreases, also refer to Minimum
tread depth on page89.
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 system, and the transmis-
sion may be damaged.<
Using 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.<

Engine oil
Engine oil consumption depends on driving
style and operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up red:
The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top off as needed. If the oil level is correct:
have the system checked immediately.
Do not continue driving. The engine could
be damaged because of inadequate lubri-
cation.<
Engine oil level
The warning lamp lights up yellow dur-
ing driving. In addition, an acoustic sig-
nal sounds.
The oil level is at the absolute minimum. Add
engine oil as soon as possible. Until then, do not
drive more than approx. 30 miles/50 km.
The warning lamp lights up yellow after
the engine is switched off. In addition,
an acoustic signal sounds.
Top off engine oil at the earliest opportunity,
e.g. when refueling.
Engine oil sensor
The warning lamp lights up yellow
within 30 seconds after starting the
engine:
The oil level sensor is defective. Have it
checked as soon as possible.
Checking oil level
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Switch off engine.
3.After approx. 5 minutes, pull the dipstick out
and wipe it off with a clean lint-free cloth,
paper towel, or similar material.4.Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two
marks on the dipstick.
5.Push the oil dipstick into the dipstick tube
as far as possible again.
The oil quantity between the two marks of the
dipstick is approx. 1.1 US quarts/1 liter.
Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.<
Adding engine oil
Do not add oil until the oil level has dropped to
just above the lower marking on the dipstick,
refer to page94.
Add oil within the next 30 miles/50 km;
otherwise, engine damage could result.<
Keep oil, grease, etc. out of reach of chil-
dren and heed warnings on the contain-
ers. Otherwise, you could endanger your
health.<
Oil change
Have the oil changed only by your BMW Sports
Activity Vehicle Center or a workshop that
