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.
The luggage compartment lid/tailgate can also
be opened with the system armed with the
button on the remote control, refer to page34.
When the luggage compartment lid/tailgate is
closed, it is locked and monitored again.
Switching off alarm
>Unlock the vehicle using the remote control,
refer to page30.
>Insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp under the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
doors, hood, luggage compartment lid/tail-
gate or rear window
is/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:
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
In order for the interior motion sensor to func-
tion properly, the windows and 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 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 enables you to access your
vehicle without having to hold the remote con-
trol in your hand. It is sufficient to carry the
remote control with you, e.g. in your jacket
pocket. The vehicle automatically detects the
related remote control in the immediate vicinity
or in the interior.

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 obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject 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.
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. Braking safely refer to page127.
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.
DBC Dynamic Brake Control
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.

1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 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
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
rear backrest.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
>Do not pile objects higher than the top edge
of the backrest.
>Sports Wagon:
Use the separation net to protect the occu-
pants, refer to page120. Make sure that
objects cannot penetrate through the sepa-
ration net.
Wrap sharp-edged or pointed objects
which could strike the rear window while
driving.
