Indicator and warning
lamps
Technology that monitors itself
Indicator and warning lamps that are iden-
tified by
+ are tested for proper functioning
whenever the ignition key is turned. They
each light up once for different periods of
time.
If a fault should occur in one of these sys-
tems, the corresponding lamp does not go
out after the engine is started or it lights up
again while the vehicle is moving. The indi-
cated pages provide information on what
measures to take.

Keys
The key set
1Master keys with remote control: they
determine the functions of the Key
Memory, refer to page 31.
You can mark individual keys for subse-
quent identification by applying the col-
ored decals that you received when
accepting delivery of your vehicle
There is an extended-life battery
in every master key that is
charged automatically in the ignition
lock as you drive.
For this reason, if you have a master key
with remote control that is otherwise
not used, use that key approximately
once a year while driving for an
extended period to charge the bat-
tery.<
2Spare key for storage in a safe place,
such as in your wallet.
This key does not open the lock of the
luggage compartment lid – useful for
valet parking, for example.
This key is not intended for constant
use
Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. The system simultaneously
engages and releases the locks on the>doors
>luggage compartment lid
>fuel filler door
>storage compartment between the
backrests
>opened manual convertible top.
The central locking system can be oper-
ated
>from outside using the remote control
or via the driver's door lock
>from inside via the central locking sys-
tem button.
If it is operated from inside, the fuel filler
door will not be locked. Refer to page 18.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle. It
prevents the doors from being unlocked
with the lock buttons or release handles.
The alarm system is also armed.
The central locking system unlocks auto-
matically in the event of an accident. In
addition, the hazard warning flashers and
interior lamps come on.
Remote control
The concept
The remote control provides two additional
functions for central locking.
>Switching on interior lamps, refer to
page 17.
With this function, you can also search
for the vehicle when parked in an
underground garage, for instance
>Opening the luggage compartment lid
separately, refer to page 17. It will open
slightly, regardless of whether it was
locked or unlocked.
Whenever you unlock or lock the vehicle,
you simultaneously deactivate/activate
the anti-theft system, disarm/arm the alarm

Opening and closing
26
Arming and disarming the alarm
system
When the vehicle is locked or unlocked
either via the driver's door lock or with the
remote control, the alarm system is simul-
taneously armed or disarmed.
The hazard warning flashers blink once
when the alarm system has been properly
armed.
You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can still open the luggage compart-
ment lid when the system is armed by
pressing the remote control button, refer to
page 17. When it is closed, the lid is once
again secured.
Manual operation of the luggage
compartment lid triggers the alarm.
Refer to page 19.<
To cancel an alarm:
Press the button on the remote control,
refer to page 16, or turn the ignition key to
position 1. Refer to page 36.
Indicator lamp displays
>The indicator lamp beneath the interior
mirror flashes continuously:
The system is armed
>The indicator lamp flashes when it is
being armed:
A door, the hood or luggage compart-
ment lid is not completely closed. Even
if you do not close the area causing the alert, the remaining areas are secured
and the indicator lamp flashes continu-
ously after 10 seconds.
However, the interior motion sensor is
not activated
>If the indicator lamp goes out as soon
as the system is disarmed:
No manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>If the indicator lamp flashes for
10 seconds when the system is being
disarmed:
An attempted entry has been detected
in the period since the system was
armed.
After an alarm has been triggered, the indi-
cator lamp will flash continuously.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger.
Deactivate the interior motion sensor,
refer to Avoiding unintentional alarms,
if children or animals are to remain in the
vehicle.<
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor can be deactivated at the same
time. You can do this to prevent a false
alarm from being triggered, for instance in
garages with elevator ramps or when the
vehicle is transported by train.
Lock the vehicle twice = arm the system:
Press the button on the remote control
twice in succession,
or
lock the vehicle twice with the key. Refer to
page 18.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor are
deactivated as long as the system is
armed.

Damaged safety belts
If the safety belts are damaged or
stretched in an accident: have the
entire belt system, including the tensioning
mechanisms, replaced at your BMW cen-
ter. Have the belt anchorage points
inspected for damage at the same time.
Failure to observe this precaution may pre-
vent the safety belts from effectively pro-
viding optimal protection when needed.<
Steering wheel
Adjustments
Never attempt to adjust the steering
wheel while driving the vehicle. It
could respond with unexpected move-
ment, posing a potential accident hazard.<
1.Push the locking lever downward
2.Adjust the steering column's reach and
height to suit your seat position
3.Pull the lever back in.

Driving
42 You accelerate from higher gears, e.g. dur-
ing passing, by downshifting manually.
In the following situations, the SMG in the
sequential mode assists you:
>The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed cannot be
executed
>During a stop the gearbox is automati-
cally downshifted into first gear
>Shortly before a gear-dependent mini-
mum speed is reached, the gearbox
shifts down automatically without you
taking any action.

The currently engaged gear, the selected
mode, and any possible malfunctions are
displayed in the instrument cluster.
Malfunctions
Indicator lamp
If the indicator lamp comes on,
there is a malfunction in the trans-
mission system.
All of the selector lever positions can con-
tinue to be engaged; however, in the for-
ward drive positions the range of available
gears is restricted.
If this happens, avoid extreme engine loads
and consult the nearest BMW center.
Warning tone
An acoustic signal sounds if the SMG gear-
box overheats; if possible you should either
stop or increase your pullaway speed so
that the system can cool down.
For jump-starting and towing, refer to the
information on page 94.
Driving Dynamic Control
The Driving Dynamic Control feature lets
you select between a standard and a sport
program.
Sport program
>The engine responds more spontane-
ously to any motion of the accelerator
pedal
>The vehicle is steered more directly and
traction is enhanced
Additionally with SMG and automatic
transmission:
>The shifting times are reduced
>The engine speed range is optimally uti-
lized in the drive mode.
Activating the Sport program
In ignition key position 2
Press the SPORT button.
The LED in the button lights up.
With automatic transmission:
The sport program of the automatic
transmission is enabled by activating the
Driving Dynamic Control system. Thus, the
selector lever does not have to be shifted
from D to M/S; refer also to page 39.<

Lamps

Lamps
Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle
lighting is switched on. You can use
the parking lamps to signal the
position of the vehicle when it is parked.
For information on lighting on one side of
the vehicle for parking, which is available
as an additional feature, refer to page 47.
Low beams
When you switch off the ignition
with the low beam headlamps on,
only the parking lamps will remain
on.
Defective bulbs
The indicator lamp lights up:
At least one bulb of the vehicle's
exterior lighting has failed.
For replacing bulbs refer to page 88.
Follow me home lamps
When you activate the headlamp flasher
after parking the vehicle and switching off
the lights, the low beams will come on for a
brief period.
You can also have this function acti-
vated/deactivated if you wish.<
LIGHTS ON warning
Whenever you open the driver's door after
having turned the ignition key to position 0,
you will hear an acoustic signal for a few seconds to remind you that the lamps have
not been switched off
.
Daytime driving lamps*
If you desire, the light switch can be left in
the second position:
When the ignition is switched off, the exter-
nal lighting is also switched off.
You can have the activation settings
for the daytime driving lamps pro-
grammed on your vehicle.<
Automatic headlamp control*
When the switch is set to this posi-
tion, the system automatically acti-
vates and cancels the low beams in
response to changes in ambient light, for
example in tunnels, at dusk, and when it is
raining or snowing.
The vehicle's external lights remain
on constantly when you switch on the
front fog lamps after the headlamps have
come on automatically.<
Automatic headlamp control cannot
serve as a substitute for the driver's
judgement in determining when the vehicle
lights should be switched on. For example,
the sensors are not able to detect fog. To
avoid safety risks, you should respond to
these kinds of low-visibility situations by
switching the headlamps on manually.<
You can have the sensitivity of your
vehicle's automatic headlamp control
adjusted.<

Dynamic Stability Control
DSC
The concept
This system optimizes driving stability and
traction, especially when just starting off,
when accelerating or when cornering. It
also maintains vehicle stability, even in crit-
ical driving situations.
DSC recognizes unstable vehicle condi-
tions, such as understeering or oversteer-
ing, and, within physically feasible limits,
helps keeping the vehicle on a steady
course by reducing engine speed and by
brake applications at individual wheels.
The DSC is operational every time you start
the engine. It includes the following func-
tions:
>Automatic Stability Control plus Trac-
tion ASC+T
>Dynamic Traction Control DTC
>Dynamic Brake Control DBC
The laws of physics cannot be
repealed even with DSC. It will always
be the driver's responsibility to drive in a
manner that matches road conditions. We
therefore urge you to avoid using the addi-
tional safety margin of the system as an
excuse for taking risks.
Do not make any modifications to the DSC
system. Allow only authorized technicians
to perform service procedures on the
DSC.<
Indicator lamps
The indicator lamps in the instrument clus-
ter go out shortly after you switch on the
ignition.
Dynamic Stability Control DSC indi-
cator lamp flashes:
The system is active and governs
drive torque and braking forces.The indicator lamp stays lit:
