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 page207.
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.<
Operation after interruptions in power
supply
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.

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.<

Things to remember when driving
Breaking-in
Moving parts need time to adjust to one
another. To ensure that your vehicle continues
to furnish optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing information.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive with changing engine and vehicle speeds,
but do not exceed:
4500 rpm or 100 mph/160 km/h
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors.
Following component replacements
Follow the break-in sequence again if compo-
nents addressed above must be replaced again
during subsequent driving.
General driving notes
Closing luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed. Otherwise, exhaust fumes could pene-
trate into the passenger compartment.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
luggage compartment lid open:
1.Close all windows and the glass sunroof.
2.Adjust the automatic climate control's
blower to supply a high rate of airflow, refer
to page106.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on exhaust system.
Do not remove the heat shields installed adja-
cent to it, and never apply undercoating to
them. When driving, standing at idle, and park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, accompa-
nied by the risk of serious property damage and
personal injury.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communications
device can affect each other. In addition, there
is no assurance that the radiation which results
during transmission will be discharged from the
vehicle interior.<
