The key set
1Master keys with remote control.
They specify the functions of the Key
Memory. In the process individual func-
tions of your vehicle can behave differ-
ently depending on the key used, see
further below.
To differentiate, you can mark the keys
with remote controls using the color-
coded decals you received on taking
delivery of the vehicle
There is an extended-life battery
in every master key with remote
control which is charged automatically
in the ignition lock as you drive.
If you have any master keys with remote
control that are not used on a regular
basis, you should therefore remember
to recharge these units by using them
to drive the vehicle for an extended
period at least every six months, also
refer to page 28.<
2Spare key for storage in a safe place,
such as in your wallet.
The locks for the luggage compartment
lid and the hotel function, refer to
page 30, cannot be operated with this
key. This is an advantage in a hotel, for
example. The key is not intended for
constant use
Replacement keys
Additional or replacement keys are avail-
able at your BMW center.
Key Memory
How the system functions
Doubtless you have often reflected on how
great it would be if you could configure
your vehicle's various adjustment settings
to meet your own personal requirements.
BMW has designed several freely select-
able options into the vehicle during its
development. You can set these as desired
via the Control Center.
You can have up to four different basic set-
tings adjusted for four different persons for
the specific keys. The only requirement is
that each person uses his or her own mas-
ter key with remote control.
When your vehicle is unlocked with the
remote control, the vehicle recognizes the
individual key by means of a data exchange
and makes adjustments accordingly.
Examples of Key Memory functions
>Automatic adjustment of the driver's
seat
>Locking the vehicle after moving off
>When unlocking with the remote con-
trol, either unlock only the driver's door
or the entire vehicle
>Activating visual warning for PDC Park
Distance Control
>Resetting volume setting.
Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Compartment in the front center con-
sole

If it is no longer possible to lock the vehicle
via the remote control, the battery is dis-
charged. Use this remote control during an
extended drive; this will recharge the bat-
tery, refer to page 26.

Opening and closing
32 If special circumstances should make it
absolutely necessary to operate the vehicle
with the lid open:
1.Coupe: close both windows as well as
the glass roof
Convertible: with closed top, close all
windows
2.Adjust the automatic climate control to
supply a high air volume, refer to
page 89.
Luggage compartment
There are four lashing eyes on the inner
corners of the luggage compartment for
securing luggage nets or securing straps to
fix luggage in position.
Also refer to Cargo loading, page 104.
Convertible: increasing luggage
compartment capacity
With the convertible top closed, you can
enlarge the luggage compartment capac-
ity:
To do so, unfold the handle and press it
downwards in the direction of travel, refer
to arrow. This folds the convertible top
compartment floor upwards.
Before opening the convertible top, run this
procedure in reverse order.
The convertible top cannot be
opened if the convertible top com-
partment floor is folded up.<
Alarm system
The concept
The vehicle alarm system responds:
>When a door, the hood, or the luggage
compartment lid is opened
>To movement in the vehicle interior:
interior motion sensor
>To changing of the vehicle's tilt if some-
one attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a
period of approx. 30 seconds
>The hazard warning flashers for approx.
5 minutes
>The high beams, which flash on and off
in the same rhythm.
Arming and disarming alarm system
When you lock or unlock the vehicle, either
with the remote control or at the door lock,
the alarm system is armed or disarmed at
the same time.
The system indicates that it has been cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can also open the luggage compart-
ment lid with the system armed using but-
ton on the remote control, refer to
page 28. When you close the lid, it is
secured again.
Switching off alarm
>Unlock the vehicle using the remote
control, refer to page 27
>or turn the ignition key to position 1.

>Briefly press the switch for raising the
roof:
The roof opens and the sliding panel
moves back approx. 2 in/5 cm
>Press the switch twice beyond the
resistance point toward the rear:
The roof opens and the sliding panel
moves completely back
>To close, briefly press the switch or
push it twice beyond the resistance
point toward the front:
The roof and sliding panel close.
Opening and closing sliding panel
Ignition key as of position 1:
>Push the switch up to the resistance
point in the desired direction:
The sliding panel continues to move as
long as you continue to hold the switch
>Push the switch beyond the resistance
point in the desired direction:
The sliding panel moves automatically.
Briefly press the switch again in any
direction to stop the movement.
After switching off ignition
You can still operate the roof:
>Ignition key in position 1 for approx.
15 minutes
>In position 0 or with the ignition key
removed for approx. 1 minute, as long
as a door has not been opened.
For information on using the convenience
operation mode at the door lock or with the
remote control, refer to page 27 or 29.
Anti-trapping mechanism
If the glass roof encounters resistance
when closing from the raised position, the
closing action is interrupted and the glass
roof opens.
If the sliding panel encounters resistance
when closing within approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens approx. 8 in/20 cm.
Despite the anti-trapping mechanism,
you should always inspect the roof's
travel range prior to closing it, as the safety
feature might fail to detect certain kinds of
obstructions, such as very thin objects, and
the roof would continue closing.
The anti-trapping mechanism for closing
the glass roof is deactivated if the switch is
pressed beyond the resistance point and
held there. The closing action is immedi-
ately interrupted when you release the
switch.<
Following interruptions in electrical
power supply
After disconnecting the battery, it can
occur that the glass roof does not move.
The system has to be initialized. Should
this occur, please have the roof initialized
at your BMW center.
Manual operation
In the event of an electrical malfunction,
you can operate the panorama glass roof
and the sliding panel manually.
Glass roof

2.Insert the Allen wrench supplied with
the onboard tool kit in the opening pro-
vided, refer to arrow.

Opening and closing
38 Partial vacuums that occur at higher
speeds in the passenger compart-
ment can make the convertible top flap.
Use the ventilation controls to increase the
air supply so that no partial vacuum occurs
in the vehicle.<
To close the electrically activated side
windows while the vehicle is being
driven, always close the rear windows or
all four windows simultaneously first, as
otherwise the windows cannot close tightly
at higher speeds.<
Prior to opening and closing

safety precautions that appear above
>Ensure that the convertible top com-
partment floor in the luggage compart-
ment is folded down, refer to page 32,
as otherwise the convertible top cannot
be opened
>Ensure that the luggage compartment
lid is closed.

A congenial climate
92 climate control is optimized for driving with
the convertible top open. In addition, the air
supply is increased as the speed increases.
If the convertible program has been
selected, it is automatically active every
time the top is opened.
The effect of the convertible program
can be greatly enhanced if the wind
deflector is fitted.<
Ventilation
You can use the serrated dials 1 to open
and close the vent outlets through an infi-
nitely-variable range, while the levers 2
allow you to adjust the airflow direction.
Do not drop any foreign bodies into
the vent outlets, as otherwise these
could be catapulted outwards and lead to
injuries.<
Ventilation for cooling
Adjust the vent outlets to direct the flow of
cool air in your direction, for instance, if the
interior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen
from the incoming air. The activated-char-
coal filter provides additional protection by
filtering gaseous pollutants from the out-
side air. Your BMW center replaces this
combined filter as a standard part of your
scheduled maintenance.You can select a display of more detailed
information in the service requirement dis-
play, refer to page 65.
Independent ventilation
The independent ventilation blows air into
the passenger compartment to lower inte-
rior temperatures.
The independent ventilation is controlled
using the Control Center. You can set two
different times for the system to start.
The independent ventilation remains on for
30 minutes. It can also be switched on and
off directly. Since the system uses a sub-
stantial amount of electrical current, you
should refrain from activating it twice in
succession without allowing the battery to
be recharged in normal operation between
use.
The independent ventilation is ready for
use at any outside temperature up to igni-
tion key position 1.
The air emerges through the upper body
region vent outlets in the instrument panel.
These vent outlets must be open for the
system to operate.

What to do if …
>you request the current position of your
vehicle, but do not receive a precise
display?
The system is unable to receive enough
GPS signals at your current position
owing to obstructions, your current
position is not yet available on your nav-
igation DVD, or the system is in the pro-
cess of calculating your current posi-
tion. As a rule, reception is guaranteed
under a clear sky
>the destination guidance does not
apply a destination?
The data of the destination is not stored
on the navigation DVD that is loaded.
Select a destination that is as close as
possible to the original
>the destination guidance does not
apply an address without the street
name?
On the navigation DVD, no downtown
area can be determined for the city or
town entered. Enter any street, or a
destination such as the railway station
etc., then start the destination guidance>you want to enter a destination for the
destination guidance, but it is not pos-
sible to select the letters for your
desired entry?
The destination data is not recorded on
the navigation DVD that is loaded. In
this case, the system will not offer you
any letters to choose from. Select a
destination that is as close as possible
to the original
>the system stops furnishing directions
on which way to turn as you approach
intersections?
You are driving in an area that has not
yet been completely recorded on the
navigation DVD. Instead of an arrow
indicating a turn, you will see an arrow
which indicates the general direction of
your planned route. Or you have left the
recommended route and the system
requires a few seconds to calculate a
new recommended route
>the battery has been disconnected?
It will take approx. 10 minutes for the
system to resume operation.
