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.
>After the vehicle is unlocked, the indicator
lamp goes out: no manipulation or
attempted intrusions have been detected in
the period since the system was armed.
>The indicator lamp flashes after unlocking
until the remote control is inserted into the
ignition lock, however for a maximum of
approx. 5 minutes: an attempted entry has
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if someone
attempts to steal the wheels or tow the vehicle.
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 prevents 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 vehicle is unlocked and 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.

Driving
72 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 freeway 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-
ruption, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. You should then reactivate the system only
when you are fully aware of the prior speed and
distance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Unexpected lane change
If a vehicle in front of you is behind a stopped
vehicle and unexpectedly changes lanes, you
must react yourself, as the system does not
react to stopped vehicles.
Swerving vehicles
When a vehicle swerves out of adjacent lanes
into your lane, the system does not detect the
vehicle until it is completely in your lane.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to restore the selected distance automatically.
This also applies to great differences in speed
between your vehicle and vehicles ahead, e. g.
when quickly approaching a truck. Once the
system has established that a vehicle is indeed
in front of you, it will indicate that you must
brake and/or maneuver the vehicle yourself.
Take action yourself, otherwise there is a risk of
an accident.<

Technology for comfort, convenience and safety
86
PDC with visual warning*
You can also enjoy the option of having the sys-
tem show the approach to an object on the
Control Display. Objects that are farther away
are already shown there before 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 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. curbs, can also disap-
pear 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 noises from outside and inside the vehicle
may prevent you from hearing 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 the wheels from locking during
braking. Safe steering response is maintained
even during hard braking. This increases active
driving safety.
ABS is operational every time you start the
engine. For information on safe braking, refer to
page126.
CBC Cornering Brake Control
This system provides further enhancements to
vehicle stability and steering response when
braking while cornering or when braking during
a lane change.

Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Sport automatic transmission
Insert the remote control into the ignition lock.
The engine can be switched off with the trans-
mission in neutral. Also refer to page38.
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.:
800lbs. minus 600lbs. = 200lbs.
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.
