> Insert the remote contro l all the way into the
ignition lock.
Indicator lamp displays
> The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
> The indicator lamp flashes after locking:
doors, hood or luggage compartment lid are
not properly closed. Even if you do not close
the alerted area, the sy stem begins to mon-
itor the remaining area s, and the indicator
lamp flashes continuously after approx.
10 seconds. The interior motion sensor and
the tilt alarm sensor are not activated. >
The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
> If the indicator lamp flashes after unlocking
until the remote control is inserted in the
ignition, but for no longer than 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. to attempts to steal a wheel
or tow the vehicle.
Interior motion sensor
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys-
tem is activated togeth er with the interior
motion sensor even if the hardtop is open. The
alarm can be triggered unintentionally by falling
objects such as leaves, refer to Avoiding unin-
tentional 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 duplex garages
> During transport on car-carrying trains,
boats/ships 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.

Technology for driving comfort and safety
Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
in front of
* or behind your ve hicle. To measure
the distance, there are four ultrasonic sensors
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the corner sensors, or approx. 5 ft/1.50 m
from the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually th e case when parking.
Avoid approaching an obje ct a t h i g h s p e e d , o t h -
erwise physical circumstances may lead to the
system warning being issued too late. <
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph or 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an in terval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 f t/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds >
if you remain in front of an object that has
been detected by only one of the corner
sensors
> if you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display. Have the system checked.
To avoid 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 a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 4 in/10 cm.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Display as soon as PDC
is activated.
System limitations
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 limit s that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or af ter a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously, otherwise there is a risk of personal
injury or property damage.

This function can be switched on
using the right button under the
following conditions:
> Up to 15 minutes after the engine has been
switched off
> Radio readiness is switched on.
> While the engine is at operating
temperature
> As long as battery voltage is sufficient
> At an outside temperature below

The middle LED is lit when the function is on.
Automatic recirculated-air control
AUC/recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
> LED off: outside air flows in continuously.
> Left-hand LED on, AUC mode: a sensor
detects pollutants in th e outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
> Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. 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 the air flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the ca r will deteriorate contin-
uously. <
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
Rear window defroster
The defroster switches off auto-
matically after a certain time or
when the hardtop is opened.
Ventilation
1 Lever for changing the direction of the
air flow.
2 Knurled wheels for opening and closing the
air vents.
3 Knurled wheel for adju sting the amount of
cool air from the vents to the upper body
area. In this way you can optimize the air
temperature for the upper body area.
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance if it has become
too hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the
incoming air. The activated-charcoal filter pro-
vides additional protection by filtering gaseous
pollutants from the outs ide air. Your BMW cen-
ter replaces this combined filter during routine
maintenance.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algo rithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirem ents, the system builds
the basis for trouble-free driving.
On the Control Displa y, you can have the
remaining times or distan ces for selected main-
tenance tasks and any le gally prescribed dates
displayed, refer to page 69:
> Engine oil
> Brake pads, separately for the front
and back
> Brake fluid
> Vehicle check
> Legally mandated in spections depending
on local regulations
Service data in the remote control
Your vehicle continuo usly stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this da ta from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page 72; otherwise the
effectiveness of Condit ion Based Service CBS
is not assured. <
