The individual vehicle
When you ordered your BMW, you chose vari-
ous items of equipment. This Owner's Manual
describes the entire array of options and equip-
ment available with a specific BMW model.
Please bear in mind that the manual may con-
tain information on accessories and equipment
that you have not specified for your own vehicle.
Sections describing options and special equip-
ment are marked by asterisks
* to assist you in
identifying possible differences between the
descriptions in this manual and your own vehi-
cle's equipment.
If equipment in your BMW is not described in
this Owner's Manual, please refer to the accom-
panying Supplementary Owner's Manuals.
Editorial notice
BMW pursues a policy of continuous, ongoing
development that is conceived to ensure that
our vehicles continue to embody the highest
quality and safety standards combined with
advanced, state-of-the-art technology. For this
reason, it is possible in exceptional cases that
features described in this Owner's Manual
could differ from those on your vehicle.
For your own safety
Maintenance and repair
Advanced technology, e.g. the use of
modern materials and powerful electron-
ics, requires specially adapted maintenance
and repair methods. You should therefore have
the corresponding work on your vehicle per-
formed only by your BMW center or at a work-
shop that works according to BMW repair pro-
cedures with correspondingly trained
personnel. If this work is not carried out prop-
erly, there is a danger of subsequent damage
and related safety hazards.<
Parts and accessories
For your own safety, use genuine parts
and accessories approved by BMW.
When you purchase accessories tested and
approved by BMW and Original BMW Parts, you
simultaneously acquire the assurance that they
have been thoroughly tested by BMW to ensure
optimum performance when installed on your
vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for damage
resulting from installation of parts and accesso-
ries not approved by BMW.
BMW cannot test every product made by other
manufacturers to verify if it can be used on a
BMW safely and without risk to either the vehi-
cle, its operation, or its occupants.
Original BMW Parts, BMW Accessories and
other products approved by BMW, together
with professional advice on using these items,
are available from all BMW centers.
Installation and operation of non-BMW
approved accessories such as alarms, radios,
amplifiers, radar detectors, wheels, suspension
components, brake dust shields, telephones,
including operation of any mobile phone from
within the vehicle without using an externally
mounted antenna, or transceiver equipment, for
instance, CBs, walkie-talkies, ham radio or sim-
ilar accessories, may cause extensive damage

Voice command system
The concept
The voice command system allows you to con-
trol operation of various vehicle systems with-
out removing your hands from the steering
wheel.
Individual menu items on the Control Display
can be spoken as commands. It is not neces-
sary to use the controller.
The voice command system transforms your
oral commands into control signals for the
selected systems and provides support in the
form of instructions or questions.
The voice command system uses a special
microphone located in the area of the interior
rearview mirror, refer to page14.
Precondition
Via iDrive, select the language in which the
voice command system is operating, so that the
spoken commands can be identified. Selecting
the language for iDrive, refer to page86.

>Press the switch to the resistance point:
All windows open as long as you press the
switch.
>Press the switch beyond the resistance
point:
All windows open automatically. Press the
switch again to stop the opening move-
ment.
>Pull the switch:
All windows close as long as you pull the
switch.
After switching off the ignition
When the remote control is removed or the igni-
tion is switched off, you can still operate the
windows for approx. 1 minute as long as no
door is opened.
For information on convenient operation via the
remote control or the door lock, refer to page29
or32. For information on closing with conve-
nient access, refer to Locking on page30.
Pinch protection system
If the closing force exceeds a specific value as a
window closes, the closing action is interrupted
and the window reopens slightly.
Despite the pinch protection system
check and clear the window's travel path
prior to closing it, otherwise the safety system
might fail to detect certain kinds of obstruc-
tions, such as thin objects, and the window
would continue closing.
Do not install any accessories that might inter-
fere with window movement. Otherwise the
pinch protection system could be impaired.
Convertible: the rear windows are not equipped with pinch protection. Therefore, watch them
closely when closing to avoid personal injury.<
Closing without pinch protection
If there is an external danger, or if ice on the win-
dows, etc., prevents you from closing the win-
dows normally, proceed as follows:
1.Pull the switch past the resistance point and
hold it there. Pinch protection is limited and
the window reopens slightly if the closing
force exceeds a certain value.
2.Pull the switch again past the resistance
point within approx. 4 seconds and hold it
there. The window closes without pinch
protection.
Coupe: glass roof*, electric
To prevent injuries, watch the glass roof
while closing it.
Take the remote control with you when you
leave the car, otherwise children could operate
the roof and possibly injure themselves.<
Raising
Press the switch.
>The closed glass roof is raised and the slid-
ing visor opens slightly.
>The open glass roof automatically travels
into the raised position. The sliding visor
remains completely open.

opening provided. Move the glass roof in
the desired direction.
6.Reinstall the control unit and reattach the
lamp cover.
Convertible: retractable
hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
The following tips will enhance your driving
pleasure in your convertible:
>It is advisable that you close the retractable
hardtop when you park the vehicle. Not only
does the closed hardtop protect the vehicle
interior against unanticipated weather dam-
age, it also offers theft protection. However,
even when the hardtop is closed, valuables
should only be stored in the locked cargo
bay.
>Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
>Do not attach rack systems to the luggage
compartment lid, and in particular do not
attach magnetic racks.
>When the retractable hardtop is operated,
the luggage compartment lid swings back
and up. Before operating the retractable
hardtop, ensure that there is enough clear-
ance, e.g. when parked in front of a wall.
>If you open the hardtop while it is wet, e.g.
after driving in the rain, water may drip into
the cargo bay. If necessary, remove items from the cargo bay beforehand to avoid
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the luggage compart-
ment lid, otherwise they could fall during move-
ments of the retractable hardtop and cause
damage or injury.
Never move the retractable hardtop when the
rollover protection system is in the activated
position.
Driving when the hardtop is not fully opened or
closed may result in damage or injury.
Do not reach into the mechanism while the
hardtop is opening or closing. Keep children
away from the swiveling area of the retractable
hardtop.<
The retractable hardtop cannot be moved
at temperatures below + 147/–106. A
message appears on the Control Display.<
The retractable hardtop can only be
opened and closed when the vehicle is
stationary. To avoid causing damage, do not
drive off until the hardtop has stopped mov-
ing.<
Before opening and closing
>Comply with the safety precautions
described above.
>Ensure that the cargo bay partition is folded
down and engaged on both sides, refer to
page117, otherwise it will not be possible
to open the retractable hardtop.
>Do not place any objects next to or on the
cargo bay partition and close the storage
compartment on the left side of the cargo
bay.
>Do not exceed the maximum loading height
under the cargo bay partition; refer to the
label in the cargo bay showing a line indicat-
ing the maximum height.
>Ensure that the luggage compartment lid is
closed.
>The vehicle should be parked on fairly level
ground. Excessive angle is indicated by a
lamp.

In exceptional cases, if the parking brake
has to be used to slow or stop the car, do
not pull the lever up too hard. In doing so, con-
tinuously press the button of the parking brake
lever.
Otherwise, excessive force on the parking
brake can lock up the rear wheels and cause the
rear of the car to swerve.<

When shifting into 5th or 6th gear, press
the gearshift lever to the right. Otherwise
the engine could be damaged if you inadvert-
ently shift into 3rd or 4th gear.<
Reverse gear
Select this only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.

sible that the system prerequisites for operation
are currently not met.
Calling up Check Control messages, refer to
page84.<
Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page83.
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 is 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 high-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce
fatigue and tension, while increasing your
enjoyment of driving. Please use it safely and
responsibly.
Within the limits of its capability, the system
automatically adapts the car's speed to that of a
slower vehicle in front of you. You can specify
