Central locking system
The concept
The central locking system functions when the
driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
>Trunk lid
>Fuel filler flap
Operating from outside
>Via the remote control
>Via the door lock
*
>In cars with Comfort Access*, via the han-
dles on the driver's and front passenger
doors
In addition, if the remote control is used, the
welcome lamps
*, interior lamps and the door's
courtesy lamps
* are switched on or off. The
alarm system
* is also armed or disarmed.For further details on the alarm system
*, refer
to page24.
Operating from inside
By means of the button for central locking, refer
to page22.
In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle
could lock the doors from the inside. You
should therefore take the remote control with
you when you leave the vehicle so that the latter
can be opened from outside.<
Convertible: to operate the convertible
top with the remote control, the doors and
trunk lid must be closed and the cargo area par-
tition must be folded down and engaged on
both sides. Refer also to page32.<
Unlocking
Press the button.
The interior lamps, the courtesy lamps
* and the
welcome lamps come on.
Setting unlocking characteristics
You can set whether only the driver's door or
the entire vehicle is to be unlocked when the
button is pressed for the first time.
For operating principle refer to page59.
1.Switch on the ignition, refer to page47.
2.Lightly push button1 in the turn indicator
lever up or down repeatedly until the sym-
bol appears in the display accompanied by
the word "SET".

Technology for driving comfort and safety
Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals warn you of
the presence of an object behind your vehicle.
Four ultrasonic sensors in the bumper measure
the distance.
An acoustic warning does not sound until an
object is closer than approx. 2 ft/60 cm to the
corner sensors, or closer than approx. 5 ft/
1.50 m to the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed; oth-
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. 55 yd/50 m of driving or above
approx. 20 mph/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 interval 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 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds:
>If you stop 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. 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 1 ft/30 cm.
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 limits 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 after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC
signal. Therefore, always drive cautiously; oth-
erwise, there is a risk of personal injury or prop-
erty damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.

Technology for driving comfort and safety
66 >When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
>When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
>When driving with snow chains
Activating DTC
Press the button; the indicator lamps for DTC in
the instrument cluster come on.
For better control
If the indicator lamp flashes:
DTC is regulating the drive and braking
forces.
If the indicator lamps are on:
DTC has been activated.
Deactivating DTC
Press the button again; the DTC indicator
lamps in the instrument cluster go out.
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.<
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. This change is detected
and is reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<

Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low road speed
range, e.g. in a town or when parking, the steer-
ing angle is increased, i.e. steering becomes
very direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page65.
Malfunction
The warning lamps come on. Active
steering is malfunctioning or is tem-
porarily deactivated. At low speeds,
greater steering wheel movements
are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. The stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initialization may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
If there is a defect, a corresponding message
appears. Have the system checked.
Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wheels relative to the vehi-
cle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
This system functions automatically.
Malfunctions
Malfunctions are displayed via Check Control,
refer to page62.

When you open the driver's door with the igni-
tion switched off, the exterior lighting is auto-
matically switched off if the light switch is in
position 0, 2 or 3.
Switch on the parking lamps if necessary,
switch position 1.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps,
refer to page76.<
Low-beam headlamps
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation. The adap-
tive light control
* is active. The LED next to the
symbol is illuminated when the low beams are
on. You can also activate the daytime running
lights, refer to page75. In the situations
described above, the lamps then automatically
switch from daytime running lights to low
beams.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
low-beam headlamps manually under these
conditions.<
Welcome lamps
If you leave the light switch in position 2 or 3
when you park the car, the parking lamps and
the interior lamps light up briefly when you
unlock the vehicle.
Pathway lighting
If you activate the headlamp flasher after
switching off the ignition with the lamps
switched off, the low beams come on and
remain on for a certain time.
Setting the duration or deactivating
For operating principle refer to page59.

Adaptive light control*
The concept
Adaptive light control is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves at speeds up to 40 mph/70 km/h,
e.g. on mountainous roads or when turning, an
additional, corner-illuminating lamp is switched
on that lights up the inside area of the curve.
Activating adaptive light control
With the ignition switched on, turn the light
switch to position 3, refer to page74.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
Standstill function
*: to avoid blinding oncoming
traffic, the adaptive light control directs light
towards the front passenger side when the
vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are active and switched on on
both sides.
Malfunction
The LED next to the symbol for automatic head-
lamp control flashes. Adaptive light control is
malfunctioning or has failed. Have the system
checked as soon as possible.

There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressure point for approx.
1second, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the
engine.<
Switching off
Press the lever in the opposite direction to the
pressure point, arrow 3.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handles this task for you and
gives you the benefit of the best possible view.

You can intervene at any time and switch the
high beams on and off as usual.
Activating the system
1.Turn the light switch to position3, refer to
page74.
2.With the low beams switched on, briefly
push the turn indicator lever in the direction
of the high beam.
The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-
cally switches from high beams to low beams
and vice versa in response to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.
Switching the high beams on and off
manually
Whenever you wish, or when the situation
requires, you can intervene:
>If the high-beam assistant switches on the
high beams, but you would like to drive with
the low beams, simply switch off the high
beams using the turn indicator lever. This
deactivates the high-beam assistant.
To reactivate the system, briefly push the
turn indicator lever toward the high beams
again.
>If the high-beam assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deactivates the system and
the high beams need to be switched off
manually, if necessary.
To reactivate the system, briefly push the
turn indicator lever toward the high beams
again.
>Use the headlamp flasher as usual with the
low beams switched on.
System limitations
The high-beam assistant cannot serve as
a substitute for the driver's personal judg-
ment of when to use the high beams. Therefore,
manually switch off the high beams in situations
where this is required to avoid a safety risk. such as the following, and driver intervention
may be necessary:
>In very unfavorable weather conditions,
such as fog or heavy precipitation
>In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings
>In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways
>In poorly lit towns and cities and in the pres-
ence of highly reflective signs
>At low speeds
>When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
>If the sensor is dirty. Clean the sensor on
the front of the interior rearview mirror using
a cloth moistened with a small amount of
glass cleaner.
Fog lamps*
To switch on/off, press the button.
The parking lamps or low beams must
be switched on for the fog lamps to
operate. The green indicator lamp in
the instrument cluster lights up whenever the
fog lamps are on.
The fog lamps are switched off while you acti-
vate the headlamp flasher or switch on the high
beams.

Things to remember when driving
98
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise, greater
clutch wear will result.<
For more information about the drive-off assis-
tant, refer to page66.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page50.
Never drive with the clutch held down,
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise, pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
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. This can ultimately
result in a sudden blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
