Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking: the
doors, hood or luggage compartment lid are
not properly closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. However, the interior motion
sensor is not activated.
>The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
>The indicator lamp flashes after unlocking
until the remote control is inserted into the
ignition lock, however for a maximum of
approx. 5 minutes: your vehicle has been
disturbed while you were away.
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
Coupe:
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
*
must be completely closed.
Convertible:
Monitors the interior up to the height of the seat
cushions. This means that the alarm system,
including the interior motion sensor, is armed
even if the convertible top is open. Falling objects, e.g. leaves, can trigger false alarms,
refer to Avoiding unintentional alarms.
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 two-level garages
>When transporting on car-carrying trains,
by sea or on a trailer
>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 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.
Comfort access*
Comfort access allows you to access your vehi-
cle without having to hold the remote control in
your hand. It is sufficient to carry the remote
control with you, e.g. in your jacket pocket. The
vehicle automatically detects the associated
remote control in the immediate vicinity or in
the interior.
Comfort access supports the following func-
tions:
>Unlocking/locking vehicle
>Comfort closing with Coupe
>Opening luggage compartment lid sepa-
rately
>Starting engine
Functional requirement
>The vehicle or the luggage compartment lid
can only be locked if the vehicle detects that
the remote control you are carrying is out-
side the vehicle.

If the sensor is not aligned properly, e. g. due to
damage, the active cruise control cannot be
activated.
System limitations
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on free-
way-type roadways where traffic is moving rel-
atively smoothly. Do not use this system in city
driving; in complex driving situations; on curvy,
winding roads, slippery roads or roads with
sharp curves such as highway off-ramps; during
inclement weather such as snow, strong rain or
fog; or when entering interchanges, service/
parking areas or toll booths. It is also important
to regulate your vehicle’s speed and distance
setting within applicable legal limits. Always be
ready to take action or apply the brakes if nec-
essary, especially when the system is actively
following a vehicle in front of you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. For example, the system may not detect
vehicles driving ahead if they suddenly brake
heavily in stop-and-go traffic during accelera-
tion. The system will not apply the brakes or
slow your vehicle when a very slow-moving
vehicle, stopped vehicle or stationary object is
in the lane ahead of you, for example when
approaching a traffic light or parked vehicle or
when a vehicle is stalled in your lane. Also, the
system does not react to oncoming traffic, pedestrians or other types of potential traffic
s u c h a s a r i d e r o n a h o r s e b a c k . I t i s a l s o p o s s i b l e
that the system may not detect smaller moving
objects such as motorcycles or bicycles. Be
especially alert when encountering any of these
situations as the system will neither automati-
cally brake, nor provide a warning to you. Also,
be aware that every decrease in the distance
setting allows your vehicle to come closer to a
vehicle in front of you and requires a heightened
amount of alertness.<
The system cannot allow the vehicle to drive off
automatically in situations that make driving off
considerably more difficult, e.g. on steep uphill
grades, with a heavy trailer or before raised
areas in the road.
Near radio astronomy stations, the system
radar is deactivated at speeds under 20 mph/
30 km/h due to legal regulations.
Be certain to interrupt the system when
you pull into an exit lane for a highway
offramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system’s
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
In addition, the system is interrupted
whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any inter-
Technology for comfort, convenience and safety
88 a signal tone sounds. The setting is stored for
the remote control currently in use.
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Turn the controller until "Settings" is
selected and press the controller.
4.Turn the controller until "Vehicle / Tires" is
selected and press the controller.
5.Change to upper field if necessary. Turn the
controller until "PDC" is selected and press
the controller.
6.Select "PDC display on" and press the con-
troller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are provided,
there is a blind spot in which objects can no
longer be detected. The system is also subject
to the physical limits that apply to all forms of ultrasonic measurement, such as those
encountered with tow bars and trailer cou-
plings, or thin and wedge-shaped objects etc.
Low objects already displayed, e. g. curbs, can
also disappear from the detection area of the
sensors again before or after a continuous tone
already sounds. Higher, protruding objects, e.g.
ledges, cannot be detected. For this reason,
drive with care; otherwise, there is a danger of
personal injury or property damage.
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 under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. For information on safe braking, refer to
page128.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
produces maximum braking force boosting and
thus helps to achieve the shortest possible
braking distance during full braking maneuvers.
This system exploits all of the benefits provided
by ABS.

Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Make sure that no fluids leak in the cargo
bay; otherwise the vehicle could be dam-
aged.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg, as otherwise the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals 800 lbs. and there will be four 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
200 lbs.:
800 lbs. minus 600 lbs. = 200 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Place heavy cargo as far forward and as low
as possible, placing it directly behind the
bulkhead behind the rear seats.
>Cover sharp edges and corners.
