58 Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, start driving right away, at a moderate
engine speed.
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 posi-
tion P: interlock.
Before driving into a car wash
To permit the vehicle to roll, take the following
steps:
1.With Comfort Access: insert remote control
into ignition lock.
2.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
Pay attention to the messages on the Info Dis-
play.
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.
Manual engagement
Briefly press the button, the word PARK
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, a chime sounds, and the brake lamps
light up.
The vehicle continues to brake forcefully for as
long as you maintain pressure on the button.
When you brake the vehicle almost to a stop,
i.e., down to a speed of approximately 2 mph/
3 km/h or below, the parking brake remains
engaged.
Manual release
Briefly press the button with the ignition
switched on.
The indicator lamp on the Info Display goes
out.
As long as the remote control is inserted
into the ignition lock, you can also release
the parking brake after the engine has been
switched off. This function is useful, for exam-
ple, in automatic car washes, refer to
page123<
When leaving the vehicle, always bring
the remote control with you; this precau-
tion prevents children from disengaging the
parking brake, for example.<
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
via the "Settings" menu in iDrive.
Activation/deactivation
iDrive, for principle details, refer to page16.
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "Vehicle" and press the controller.
4.Select "AUTO P". Press the controller to
activate/deactivate the desired function.
>Automatic Hold is activated.
The green AUTO P status message on the
Info Display indicates that the system is
ready for operation.
>Automatic Hold is deactivated.
The green AUTO P status message disap-
pears from the Info Display.
You can program the programmable but-
ton on the steering wheel with the Auto-
matic Hold function, refer to page52. This gives
you the option of being able to quickly activate
or deactivate Automatic Hold without distract-
ing your attention from the road.<
Driving
The parking brake engages automatically when
the vehicle comes to a stop.
The indicator lamp on Info Display lights up
green.
To start off again, simply press the accelerator
pedal. The parking brake is released automati-
cally; the indicator lamp goes out.
Do not drive through an automatic car
wash with the Automatic Hold on and the
engine running. Otherwise, the system will

What you will need
1Screwdriver handle
2Unlocking tool
310 mm open-end wrench
You will find the required tools in the onboard
tool kit mounted on the inside of the luggage
compartment lid, refer to page213.
Insert the release tool into the screwdriver han-
dle as shown in the illustration.
Releasing
1.Remove the floor mat and the cover above
the spare tire.
2.With the attached screwdriver handle,
insert the release tool into the opening,
arrow1.
3.Fit the open-end wrench onto the hexago-
nal section of the release tool.
Insert the release tool counter to the spring
force until the stop is reached, press and
rotate in the arrow direction2 until it notice-
ably engages and meets a perceptible
resistance.
4.Without releasing, continue to turn counter
to the mechanical resistance of the drive
unit in the arrow direction 2 until you can feel a significant increase in the force of the
resistance.
To prevent possible damage to the
rear brakes, always make sure that
the parking brake is completely released
before driving the vehicle.<
5.Return the tools to their places.
6.Return the spare tire cover and the floor mat
to their original locations.
Have a malfunction corrected only by a
BMW center or a repair shop that works in
accordance with BMW guidelines and uses
appropriately trained personnel. Only techni-
cians can return the parking brake to normal
operational status after it has been released
manually in response to a malfunction.<
Following manual release, the actual sta-
tus of the parking brake may deviate from
that displayed by the indicator lamp.<
Reinitializing after a power supply
interruption
The parking brake can only be used again
if it was manually released due to an inter-
ruption in the supply of electrical power. Other-
wise, the function of the parking brake is not
guaranteed and there is a danger of the vehicle
rolling despite the parking brake being
engaged.<
Once the electrical power supply has been
restored, you can again use the parking brake:
With the ignition on and the vehicle
stationary, briefly press the button
three times at intervals of approx.
5 seconds. This executes the fol-
lowing initialization sequence:
>Initializing the disengaged setting.
>Engaging: the system registers the new
status and the brake setting is initialized.
The indicator lamp on Info Display lights
up green.
>Releasing: the parking brake is ready for
operation.
The indicator lamp on the Info Display
goes out.

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 maintaining 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
automatically, permitting you to flow with the
traffic without having to frequently intervene.
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
following distance 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. This setting is also
maintained on steep stretches, but the vehicle
speed can fall below this on uphill grades if the
engine output is insufficient to maintain speed.
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 page72.<
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. Adapt the

ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance;
failure to do so can constitute an accident haz-
ard.<
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 posi-
tion N
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 advance 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.
