ment lid cannot be opened. This is an advan-
tage when valet parking, for example.
Unlocking separately
Push the switch in the direction of arrow 2.
Emergency release
Pull the lever in the luggage compartment. The
luggage compartment lid is unlocked.
Closing
The handle recesses on the interior trim of the
luggage compartment lid make it easier to pull
down.
Make sure that the closing path of the
luggage compartment lid is clear, other-
wise injuries may result.<
Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened>To movements inside the vehicle: Interior
motion sensor, refer to the information fur-
ther below
>When the car's inclination changes, for
instance if an attempt is made to jack it up
and steal the wheels or to raise it prior to
towing away
>When there is an interruption in the power
supply from the battery
The alarm system signals unauthorized entry
attempts for a short time by means of:
>An acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams
Arming and disarming
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.
Even when the alarm system is armed, you can
open the luggage compartment lid by means of
the button on the remote control, refer to
page31. When you subsequently close the lug-
gage compartment lid, it is again locked and
monitored.
Switching off an alarm
>Unlock the car with the remote control, refer
to page30, or
>insert the remote control 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 system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx. 10
seconds. However, the interior motion sen-
sor is 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
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 duplex garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote control
twice in a row.
The indicator lamp comes on for approx. two
seconds, then begins to flash steadily. The tilt
alarm sensor and the interior motion sensor are
switched off until the next time the vehicle is
unlocked and subsequently locked again.
Convenient access*
Convenient access enables you to enter your
vehicle without needing to hold the remote con-
trol in your hand. All you need to do is wear the
remote control close to your body, e.g. in your
jacket pocket. The vehicle automatically
detects the corresponding remote control
within the immediate vicinity or in the passen-
ger compartment.
Convenient access supports the following
functions:
>Unlocking/locking the vehicle
>Unlocking the luggage compartment lid
separately
>Engine starting
>Convenient closure
Functional requirement
>The vehicle or the luggage compartment lid
can only be locked when the vehicle detects
that the remote control currently in use is
outside of the vehicle.
>The vehicle cannot be locked or unlocked
again until after approx. 2 seconds.
>The engine can only be started when the
vehicle detects that the remote control cur-
rently in use is inside the vehicle.
Special features in comparison to
conventional remote controls
In general, there is no difference between using
convenient access or pressing the buttons on
the remote control to carry out the functions
mentioned above. You should therefore first
familiarize yourself with the instructions on
opening and closing starting on page28.
Special features regarding the use of conve-
nient access are described below.

Reverse gear
Select only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.
Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated transmission in which operation of
the clutch and gearshifts are performed by an
electro-hydraulic system.
SMG is operated via the selector lever in the
center console and two shift paddles on the
steering wheel.
It offers you the following functions:
>Choice of manual or automatic operation:
sequential mode or Drive mode
>Choice of two driving programs: Normal or
Sport, refer to Dynamic Driving Control,
page56
>Automatic downshifting and prevention of
misshifting in sequential mode as well
>Acceleration assistant, refer to page57
Selector lever positions
The current selector lever position can be seen
on the center console.
>R: Reverse gear
>N: Neutral, idle
>One-touch functions for sequential mode:
+: manual upshifting
–: manual downshifting>D: Drive mode or sequential mode
N is automatically selected when the
driver's door is opened while the engine is
running, as long as the pedals, shift paddles and
selector lever are not operated.
This is indicated by an acoustic signal and a
flashing N in the instrument cluster.<
Gear indicator
R N 1 to 6
The gear currently engaged is displayed, pre-
ceded by a D in Drive mode.
This indicator is the only way you can
confirm whether or not the desired selec-
tor lever position is engaged.<
Shiftlock
Before moving the lever away from N with the
vehicle stationary, first depress the brake; oth-
erwise the desired gearshift will not be carried
out.
R Reverse
Select only when the vehicle is stationary.
Gear-change mode
The gears can be changed in two different
ways.
>Sequential mode
Gears are shifted by means of the shift pad-
dles or the selector lever.
>D Drive mode
All forward gears are shifted automatically.
You can switch from one mode to the other by
pressing the selector lever towards the right in
the direction of D.

Driving

Sequential mode
After every engine start, sequential mode is
activated when you press the selector lever
towards the right while the brake is depressed.
You can shift up or down using the shift paddles
or the selector lever. You do not need to lift your
foot from the accelerator pedal while doing so.
It is also possible to start off in second gear, e.g.
on slippery surfaces.
SMG assists you in the following situations:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; for exam-
ple, a downshift that would cause the
engine to overrev cannot be executed by
the system.
>The system shifts down into first gear auto-
matically when the vehicle comes to a stop.
>The system shifts down automatically just
before the engine speed falls below the
minimum speed required for a certain gear;
the driver does not need to intervene.
Shifting gears via selector lever
>Pull the selector lever backwards to shift up.
>Push it forward to shift down.
Shifting gears via the shift paddles on
the steering wheel
>Pull one of the shift paddles to shift up.
>Press it to shift down.
D Drive mode
In Drive mode, all forward gears are shifted
automatically.To switch from sequential mode to Drive mode:
press the selector lever towards the right in the
direction of D.
Kick-down: to accelerate rapidly, e.g. when
passing another vehicle, depress the accelera-
tor pedal all the way. You will achieve maximum
acceleration.
To switch back to sequential mode: press the
selector lever again towards the right in the
direction of D or shift gears via the shift paddles
or the selector lever.
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; engage the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Dynamic Driving Control
Dynamic Driving Control enables you to drive
your BMW in an even more performance-ori-
ented manner at the touch of a button:
>Gears are shifted more quickly.
>In Drive mode, the engine speed range is
utilized optimally.
Activating the system
Press the SPORT button while the ignition is
switched on. The LED in the button lights up.
Deactivating the system
>Press the SPORT button again or
>engage reverse gear or
>switch off the engine.
The LED in the button goes out.

Driving
58
R Reverse
Select only when the vehicle is stationary.
N Neutral, idle
You can select this in a car wash, for example.
The vehicle can roll.
D Drive, automatic position
Position for normal vehicle operation. All for-
ward gears are selected automatically.
Under normal operating conditions, fuel con-
sumption is lowest when you are driving in posi-
tion D.
Kick-down
Kick-down enables you to achieve maximum
performance.
Press the accelerator pedal beyond the full-
throttle resistance point.
Manual operation and Sport program
M/S
Move selector lever from position D toward the
left into the M/S shifting slot:
The sport program is activated and DS appears
in the instrument cluster. This position is rec-
ommended for a performance-oriented driving
style.
When you press the selector lever forwards or
backwards, the manual mode is activated and
Steptronic changes gear. The instrument clus-
ter shows M1 through M6.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The gear selected appears briefly in the instrument
cluster, followed by the gear actually in use.
To use the automatic function again, move the
selector lever to the right into position D.
Overriding selector lever lock
Should the selector lever refuse to move out of
position P although the button on the selector
lever is pressed, the selector lever lock can be
overridden:
1.Unclip the sleeve of the selector lever.
2.Pull the sleeve up over the selector lever
until the sleeve is inside out.
3.Using the screwdriver from the onboard
tool kit, refer to page205, press the red
lever while moving the selector lever to the
desired position.

2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.If necessary, move the highlight marker to
the uppermost field. Turn the controller
until "PDC" is selected and press the con-
troller.
5.Select "PDC display on" and press the con-
troller.
6. The PDC screen is activated.
The setting is stored for the remote control cur-
rently in use.
The display is shown 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 limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer towbars and couplings,
thin and wedge-shaped objects, etc. Low
objects already indicated, such as a curb, may
enter the sensors' dead areas before a continu-
ous audible signal is given. Higher, protruding
objects, such as ledges, may not be detectable.
Loud sound sources outside or inside the car
can drown out the PDC signal.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving 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 page117.
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 for the
duration of the brake application. If the brake is
released, DBC will be switched off.
DSC Dynamic Stability Control
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. DSC also recognizes unstable driving
conditions, for example if the rear of the car is
about to swerve or if momentum is acting at an
angle past the front wheels. In these cases,
DSC helps the vehicle maintain a safe course
within physical limits by reducing engine output
and through braking actions at the individual
wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<

trol Display. Initialization is then completed
while the car is in motion.
Indication of a flat tire
The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat
tire or substantial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.
If the car is not equipped with Run-
Flat Tires, refer to page196, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor
might not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 90 miles/150 km
>With a full load:
4 or more persons, luggage compart-
ment full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h. In the event
of pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or loud noises occur during the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over to the side of the road at the
earliest opportunity. Otherwise, parts of the tire
could come loose and cause an accident. Do
not continue driving. Contact your BMW Cen-
ter.<
Malfunction
The warning lamps come on in yel-
low. A message appears on the Con-
trol Display. The Flat Tire Monitor has
a malfunction or has failed. Have the
system checked as soon as possible.
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 increases, i.e. the 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 more and
more. This improves the handling capability 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 page85.
Malfunction
The warning lamps come on. Active
steering is no longer operational. At
low speeds, greater steering wheel
movements are required, whereas at
higher speeds the vehicle reacts more sensi-
tively to steering wheel movements. Drive cau-

Temperature
Set the desired temperatures indi-
vidually for the driver's and front
passenger's sides.
The automatic climate control
achieves this temperature as quickly as possi-
ble regardless of the season, using maximum
cooling or heating power if necessary, and then
maintains it.
When you switch between different tem-
perature settings in quick succession, the
automatic climate control does not have
enough time to achieve the set temperature.<
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.
The automatic climate control switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. You
should therefore open them for maximum cool-
ing.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and
