If the remote control is still in the ignition
lock when the driver's door is opened, a
gong will sound and a message will appear
in the Info Display.
Starting the engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
1.Insert the remote control all the way into
the ignition lock. With Comfort Access,
this is not required
2.Press the brake pedal
3.Briefly press the start/stop button.
Your BMW is equipped with the con-
venience starting feature. After press-
ing the brake pedal, all you need to do is
briefly press the start/stop button.
The system responds by automatically
engaging the starter and allowing it to run
until the engine starts, after which it then
disengages automatically.
The automatic starting mode will not oper-
ate or will be canceled if the battery voltage
is low. The engine can be started by jump-
starting, refer to page 207.<
Do not allow the engine to warm up by
leaving it running while the vehicle remains stationary. Instead, drive off immediately at
a moderate engine speed.
If you have accidentally switched off
the engine while driving, it can be
restarted from a speed of approx. 3 mph/
5 km/h by pressing the button. It is not nec-
essary to press the brake pedal.<
Under the following conditions you should
press the accelerator pedal halfway down
when starting:
>If the engine fails to start on the first
attempt, for instance, if it is very hot or
cold
>During a cold start at high altitudes,
from approx. 3,281 ft/1,000 m, at very
low temperatures, from approx. + 57/
Ð156.
Refrain from starting the vehicle
repeatedly at brief intervals, and
avoid an excessive number of starting
attempts if the vehicle fails to start;
repeated activation of the starter over an
extended period would allow unburned or
only partially combusted fuel to enter the
catalytic converter, where it can cause
overheating and damage to the unit.<
Switching off the engine
With the vehicle stationary, briefly press the
start/stop button. This also activates the
radio mode.
The transmission automatically shifts to
position P: interlock.
Transmission position N remains
engaged if you keep to the following
order:
1.With Comfort Access: insert the remote
control into the ignition lock
2.With the engine running, engage trans-
mission position N
3.Switch off the engine
4.Leave the remote control in the ignition
lock.
This function is useful in automatic car
washes, etc.
Position P is engaged automatically after

Driving
62 approx. 30 minutes or when you remove
the remote control from the ignition lock.
Remember to observe the Check Control
for status messages.<
Should exceptional circumstances
render it necessary for you to switch
off the engine while the vehicle is moving,
press the start/stop button for approx.
1 second.
If you maintain pressure on the start/stop
button for longer than two seconds while
switching off the ignition, the remote con-
trol will be ejected.<
Before leaving the vehicle, remove
the remote control from the ignition
lock; with Comfort Access, always take the
remote control with you.<
Parking brake
The concept
Your BMW is equipped with an electrome-
chanical parking brake.
The parking brake is primarily intended to
prevent the vehicle from rolling while
parked.
You can operate or use the parking brake in
two different ways:
>Manually, by briefly pressing the button
>Automatically, through activation of the
Automatic Hold mode, refer to page 63.
An electrohydraulic mechanism then
engages the parking brake to prevent the
rear wheels from turning whenever you
switch off the engine.
When the engine is running, parking brake
engagement is controlled by the brake sys-
tem's hydraulic circuits, which act on the
disc brakes at the front and rear wheels.
Brake pedal feel
Because this function is activated using
the brake system's hydraulic circuits, the
response of the brake pedal may change
slightly. Engagement may also be accom-
panied by activation noise Ð this is normal.
Manual engagement
Briefly press the button, the
word PARK appears briefly
in the Info Display. With the
parking brake set, the indicator
lamp lights up red in the
Info Display, refer to page 12.
With the ignition off, the indicator
lamp goes out after a brief
period.<
Manual release
With the ignition on, briefly
press the button: the indicator
lamp in the Info Display goes
out.
Provided that the remote control unit
is inserted in the ignition lock, you can
also release the parking brake after the
engine has been switched off. This function
is intended for use in automatic car
washes, etc.<
When leaving the vehicle, always
release the remote control from the
detent in the ignition lock; this precaution
prevents children from disengaging the
parking brake, etc.
The parking brake can still be engaged at
any time when the remote control unit is
released from the detent. It is only possible
to disengage the parking brake with the
ignition on.<
If exceptional circumstances should
make it necessary to engage the
parking brake while the vehicle is in motion,
maintain pressure on the button.
The indicator lamp appears in red in the
Info Display. A gong sounds at the same

time.
The brake lamps come on.
The vehicle continues to brake automati-
cally for as long as you maintain pressure
on the button.<
When you brake the vehicle to a vir-
tual stop, i.e., down to a speed of
approx. 2 mph/3 km/h or below, the park-
ing brake remains engaged.
The indicator lamp in the Info Display
lights up red. Briefly press the button to
disengage the parking brake manually.<
Automatic Hold
You can activate this feature after starting
the engine; it then remains operational until
the next time the engine is switched off.
This feature provides supplementary sup-
port during vehicle operation by automati-
cally engaging and releasing the parking
brake during stops at traffic lights, in stop-
and-go traffic, etc. As the vehicle then no
longer tends to creep when the transmis-
sion is engaged, it is no longer necessary
to hold the vehicle by pressing the brake
pedal.
It prevents the vehicle from rolling back-
ward during uphill starts.
The parking brake engages automatically
when you stop the vehicle and switch off
the engine.
You can activate or cancel the Automatic
Hold feature by selecting the "Settings"
menu in the Control Center. A description
of the Control Center is provided on
page 17.
Automatic Hold activation/
deactivation
1.Select "Settings"
2.Select and confirm
3.Select "AUTO P". Press the controller
to activate/deactivate the desired func-
tion
>Automatic Hold is activated.

the Info Display shows you that the sys-
tem is ready for operation
>Automatic Hold is deactivated.
The green AUTO P status message dis-
appears from the Info Display.
You can assign the Automatic Hold
function to the programmable button
in the steering wheel, refer to page 52.
This feature then provides you with quick
access to the Automatic Hold function,
allowing you to control it without undue
distraction from road and traffic condi-
tions.<
You can also deactivate Auto-
matic Hold by pressing the but-
ton while the vehicle is station-
ary. The vehicle remains
stationary, the indicator lamp
changes from green to red. Press the but-
ton again to release the parking brake.
Driving with Automatic Hold
The parking brake engages automatically
when the vehicle comes to a stop. The indi-
cator lamp in the Info Display lights
up green.
To start off again, simply press the acceler-
ator pedal. The parking brake is released
automatically; the indicator lamp
goes out.
Do not drive through an automatic car
wash with the Automatic Hold on and
the engine running. The system would
engage the parking brake while the vehicle
is stationary.<
Parking with Automatic Hold
The parking brake engages automatically
when you stop the vehicle and switch off
the engine. The indicator lamp
changes from green to red.

Driving
64 Provided that the remote control is
inserted in the ignition lock, you can
also release the parking brake manually
after the engine has been switched off,
refer to page 62. This function is useful in
automatic car washes, etc.
Automatic Hold is deactivated.<
When leaving the vehicle, always
release the remote control from the
detent in the ignition lock; this precaution
prevents children from disengaging the
parking brake, etc.<
For your safety
Automatic Hold is automatically deacti-
vated when
>the engine is switched off
>the system detects that the driver's seat
is not occupied while the engine is run-
ning
>the hood is opened while the engine is
running
>the luggage compartment lid is opened
with the transmission in reverse while
the engine is running, and
>when the parking brake is used to bring
the vehicle to a stop.
The indicator lamp changes from
green to red, and the AUTO P letters in the
Info Display disappear.
Before starting off again, briefly press the
button to disengage the parking brake
manually, refer to page 62, or reactivate
Automatic Hold, refer to page 63.
Before leaving the vehicle with the
engine running, always move the
automatic transmission's selector lever to
position P and ensure that the parking
brake is engaged. The vehicle could start
to roll if you fail to observe these precau-
tions.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
Automatic Hold is automatically
deactivated whenever the system
detects any tendency for the wheels to spin
in response to slippery road surfaces. Note the status reports in the Check Control.
You can find additional information on the
Check Control on page 82.<
Malfunctions
If a malfunction occurs, the indicator
lamp lights up yellow in the Info Dis-
play and a status report will appear in the
Check Control. Please note any supple-
mentary information that appears on the
Control Display.
Releasing the parking brake
manually
You can respond to any interruptions in the
supply of electrical power, for instance, if
the battery is discharged or disconnected,
by releasing the parking brake manually.
Before proceeding to release the
parking brake manually, and each
time you park the vehicle without engaging
the parking brake, always ensure that the
automatic transmission's selector lever is
in position P, refer to page 66. Note the
range indicated in the Info Display.
If the wheel must be changed on a surface
with a more severe slope, take additional
precautions to secure the vehicle from roll-
ing e.g. with a chock, refer to page 203.
Otherwise there is a danger that the vehicle
could start to roll if parked on a steep
slope.<

In case of malfunction
If the brake system warning lamp
lights up in red, together with the
yellow indicator lamps for ABS and
DSC: the stability control is no
longer operational.
If all three lamps light up in yellow:
malfunction in the stability control
systems. The electronic brake-
force distribution is active.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
Check Control messages, refer to page 82.
Please take note of the additional informa-
tion on the Control Display.

Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimized stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
Indicator lamps
The indicator lamp in the Info Dis-
play goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the Con-
trol Center.
The indicator lamp and the brake
warning lamp remain on continu-
ously:
DSC, DTC and DBC have been
deactivated or a system malfunc-
tion is present.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.

DTC Dynamic Traction Control
In particular driving situations, in deep
snow, for example, DTC ensures the maxi-
mum forward momentum. The gain in for-
ward momentum in these situations
involves a reduction in vehicle stability.
DTC is active up to 45 mph/70 km/h.

Activating DTC
You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Select "Settings". Select "DTC" and con-
firm. DTC is now activated. The DTC indi-
cator lamp in the Info Display lights up per-
manently.
When DTC is active, DSC provides
only limited system response up to a
speed of approx. 45 mph/70 km/h. Inter-
vention for stability enhancement is
reduced.<
Deactivating DTC again
Select "Settings". Select "DTC" and con-
firm. DTC is now deactivated. The DTC
indicator lamp in the Info Display goes out.
DSC is once again available without
restriction.
Switching off DSC
Select "Settings". Select "DSC" and con-
firm. DSC is deactivated. The indicator
lamp in the Info Display remains on contin-
uously.
Deactivating DSC automatically deacti-
vates DTC as well. The systems for
enhancing stability and traction are deacti-
vated, and there is no active braking inter-
vention or torque control.
A status report appears in the Check Con-
trol. Please take note of the additional
information on the Control Display.
To maintain optimized stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Select "Settings". Select "DSC" and con-
firm. DSC is now activated. The indicator
lamp in the Info Display goes out.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Avoid using the
additional safety margin provided by the
system as an excuse for taking unneces-
sary risks.
When DTC is active, DSC provides only
limited system response up to a speed of
approx. 45 mph/70 km/h. Intervention for
stability-enhancement is reduced.
Do not make any modifications to the DSC
system. Never allow anyone other than
authorized professional technicians to
carry out service or repairs on the DSC sys-
tem.<
DBC Dynamic Brake Control
When you apply the brakes rapidly, this
system automatically produces the maxi-
mum braking force boost and thus helps to
achieve the shortest possible braking dis-
tance during panic stops. This system
exploits all of the benefits provided by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released, the
DBC is deactivated.
