Special starting conditions
In the following situations, press the gas pedal
halfway down when starting:
>The engine fails to start on the first attempt,
for instance if it is very hot or cold.
>The engine is being started at extremely low
temperatures below + 57/– 156, or at
high altitudes above 3,281 ft/1,000 m.
Avoid frequent starts in rapid succession
or repeated starting attempts in which the
engine does not start. Otherwise, the fuel is
either left unspent or is insufficiently burned
and there is a risk of overheating and damaging
the catalytic converter.<
Switching off engine
When leaving the vehicle, always take the
remote control with you.<
With the vehicle stationary, briefly press the
Start/Stop button. Radio ready state is switched
on.
The transmission automatically shifts to
position P: interlock.
Before driving into a car wash
The transmission remains in position N and the
vehicle can roll when you perform the following
sequence:
1.With Comfort Access: insert remote control
into ignition lock.
2.With the engine running, shift transmission
into position N.
3.Switch engine off.
4.Leave the remote control in the ignition
lock.
The transmission will shift into position P:
>automatically after approx. 30 minutes
>if you remove the remote control from the
ignition lock
Observe the messages on the Info Display.
Removing remote control from ignition
lock
Press in the remote control briefly; it pops part-
way out. This procedure will also switch off the
ignition if it is on.
Comfort function
To switch off the engine when the vehicle is sta-
tionary, press the Start/Stop button for longer
than approx. 2 seconds. The remote control
pops partway out.
Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake.
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked.
You can use the parking brake in two ways:
>Manually, by briefly pressing the button
>Automatically, by activating the Automatic
Hold mode, refer to page59.
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 in the front and rear wheels.
Brake pedal feel
The hydraulic brake system can produce a
slightly different braking feel. Engagement may
also be accompanied by activation noise – this
is normal.

appears on the Info Display.
When the parking brake is engaged, the indica-
tor lamp on the Info Display lights up red,
refer to page12.
The remote control does not have to be
inserted into the ignition lock for the parking
brake to be set.
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 on the Info Display lights up
in red and a chime sounds, the brake lamps light
up.
The vehicle continues to brake forcefully for as

the parking brake after the engine has been
switched off. This function is useful, for exam-
ple, in automatic car washes, refer to 124<
When leaving the vehicle, always bring
the remote control with you; this precau-tion prevents children from disengaging the
parking brake, etc.<
Automatic Hold
You can activate the system after starting the
engine; it then remains operational until the
next time the engine is switched off.
This feature provides additional assistance dur-
ing vehicle operation by automatically engaging
and releasing the parking brake during stops at
traffic lights, in stop-and-go traffic, etc. The
vehicle is automatically held in place so as to
suppress the tendency to creep when the
transmission is in drive.
It also 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 deactivate Automatic Hold

ensure that the parking brake is engaged. The
vehicle could start to roll if you fail to observe
these precautions.<
Automatic Hold is automatically deacti-
vated whenever the system detects any
tendency for the wheels to spin in response to
slippery road surfaces.
Observe the messages on the Info Display. For
additional information, refer to Check Control
on page80.<
Releasing parking brake manually
In the event of an electrical power loss or elec-
trical malfunction, you can release the parking
brake manually.
Before manually releasing the parking
brake and each time you park the vehicle
without engaging the parking brake, make sure
that the automatic transmission is in position P,
refer to page62. Be sure to pay attention to the
information on the Info Display.
If circumstances should force you to park on a
steeply inclined road surface, it is essential to
take additional precautions against inadvertent
rolling, e.g. by using the chock, refer to
page209. Otherwise, there is the danger of the
vehicle rolling, depending on the incline.<

Active cruise control*
The concept
With active cruise control you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control represents a technological
advance over the familiar cruise control and is a
welcome relief from the constant adjustment of
speed that can accompany driving in traffic on
highways or other high-speed thoroughfares.
Especially on longer trips, the system can
reduce fatigue and tension, while increasing
your enjoyment of driving. Please use it safely
and responsibly.
In addition to holding a steady cruising speed,
if you encounter slower vehicles ahead, active
cruise control will, within the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that you can flow with the traffic
without having to make constant adjustments.
If, for example, while cruising at the selected
speed, you begin to approach a slower vehicle
ahead of you in the same lane, the system will
reduce your vehicle's speed to the same as that
of the vehicle ahead to maintain your selected
distance setting between your vehicle and the
vehicle ahead. You can vary the distance, which
is additionally speed-dependent. Based on
your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. The vehi-
cle brake lamps will automatically illuminate to
signal a following driver to take action. In addi-
tion, it may be necessary for the vehicle to
downshift to maintain the distance setting
selected. If the vehicle ahead speeds up or when the lane ahead becomes clear, your vehi-
cle will accelerate to the speed you have
selected by increasing the throttle setting and
shifting gears as needed. Your selected speed
will be maintained when driving downhill, too.
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
to which you may be accustomed, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section begin-
ning on page73.<
Brake pedal feel
>When the system brakes and you also
depress the brake pedal, a somewhat differ-
ent braking feeling results.
>Any noises produced during automatic
braking are normal.
Applications
As with conventional cruise control systems,
active cruise control in no way diminishes or
substitutes for the driver's own personal
responsibility, alertness and awareness in
adjusting speed, braking or otherwise control-
ling the vehicle. The driver should decide when
to use the system on the basis of road, traffic,
visibility, and weather conditions. Active cruise
control is intended for use on highway-type
roadways where traffic is moving relatively
smoothly. Do not use this system in city driving;
heavy traffic such as during rush hour; on curvy,
winding roads, slippery roads or roads with
sharp curves such as highway off-ramps; during
inclement weather such as snow, strong rain or
fog; or when entering interchanges, service/
parking areas or toll booths. It is also important
to regulate your vehicle's speed and distance
setting within applicable legal limits. Always be
ready to take action or apply the brakes if nec-
essary, especially when the system is actively

Selecting distance
>Knurled wheel up:
To increase distance
>Knurled wheel down:
To decrease distance
The selected distance is displayed in the
speedometer.
Distance 1
Distance 2
Distance 3
This distance is always set when
the system is used for the first time
after starting the engine.
Distance 4
Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, a violation of the law or the danger of
an accident could result.<
Deactivating cruise control
Press the lever up or down. The displays in the
speedometer go out.
In addition, the system is automatically deacti-
vated:
>when the speed is reduced to below 20 mph
or 30 km/h due to a traffic situation
>when DTC is activated or DSC is deacti-
vated
>when the system does not recognize any
objects for an extended period of time, e.g.
on infrequently traveled roads without a
shoulder or guard rails, or if the radar sensor
is covered with dirt, refer to page72
>when you actuate the parking brake during
driving
>when you shift the transmission into the
Nposition
If the system is deactivated, then it is nec-
essary for the driver to actively intervene
by braking and possibly swerving. Otherwise,
there is the danger of an accident.<
Background lighting
You can switch off the backlighting of the
speedometer and tachometer when the system
is deactivated if no other functions are being
displayed, e.g. the pre-warning field in the
tachometer, refer to page75, or the route guid-
ance of the navigation system.
To do so, press the lever up or down for approx.
1second.

Things to know about active cruise control
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, for example when approaching a traffic
light or a parked vehicle. Also, the system does
not react to oncoming traffic, pedestrians or
other types of potential traffic such as a rider on
horseback. It is also possible that the system
may not detect smaller moving objects such as
motorcycles or bicycles. Be especially alert
when encountering any of these situations as
the system will neither automatically brake, nor
provide a warning to you. Also, be aware that every decrease in the distance setting allows
your vehicle to come closer to a vehicle in front
of you and requires a heightened amount of
alertness.<
When your vehicle is actively following a vehicle
in front of you, if the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane may also result in accelera-
tion of your vehicle.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any deacti-
vation, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. You should then reactivate the system only
when you are fully aware of the prior speed and
distance settings.<
