Driving when the opening or clos-
ing process has not been com-
pleted can cause vehicle damage or
personal injuries.
Do not reach into the convertible top
mechanism during opening and closing.
Keep children away from the moving
parts of the convertible top during
operation.<
If possible, only operate the con-
vertible top with the vehicle
stopped, as otherwise the process may
be interrupted.
If you set the convertible top in motion
with the vehicle stationary and then
have to start suddenly – for instance, at
a traffic light – you can still complete
the operation by driving as slowly as
possible and again pressing and main-
taining pressure on the button.<
To close the electric power win-
dows while driving, always be
sure to first close either the rear win-
dows, or all 4 windows at the same
time, otherwise, at high speed, the win-
dows may not close tightly.<
At higher speeds, the ensuing
vacuum in the passenger com-
partment can cause the convertible top
to begin fluttering. Increase the air sup-
ply via the ventilation controls so that a
vacuum does not occur in the vehicle.<

Vehicle Memory, Key MemoryHow the system functionsYou have probably frequently wished
that you could configure individual
functions of your vehicles to reflect your
own personal requirements. In engi-
neering your vehicle, BMW has pro-
vided for a number of options for per-
sonal adjustment that can be
programmed into your vehicle at your
BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. You can have up to four
different basic settings adjusted for four
different persons. The only require-
ment is that each person uses his or her
own remote control key.
When your vehicle is unlocked with the
remote control, the vehicle recognizes
the individual user by means of a data
exchange with the key, and makes
adjustments accordingly.
Distinguishing between keysIn order for you to be able to distinguish
between different keys, colored decals
are supplied together with the keys.What the system can doYour BMW center can provide you with
details on the possibilities that the Vehi-
cle and Key Memory systems offer.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<
Examples for Vehicle Memory:
>Various signals that can serve as
acknowledgment for locking and
unlocking the vehicle, refer to
page 31
>Activates/deactivates the 'Follow me
home' lamps function, to page 91
>Activates/deactivates daytime driv-
ing lamps, refer to page 91
>Sets the units of measure for display-
ing time, outside temperature, dis-
tance traveled and fuel consumption
in the instrument cluster
>When you shift into Reverse, an
acoustic signal indicates that PDC
has been activated, refer to page 85
>Switches on rear window defroster
automatically, refer to page 99
>After giving an ice warning, the
onboard computer display returns to
the previous setting, refer to page 83.
Examples for Key Memory:
>Locks the vehicle automatically after
you start off, refer to page 34
>Automatically moves the seat and
outside mirror into position for the
programmed driver when unlocking
the vehicle, refer to page 51
>Automatic tilting of the passenger-
side mirror, refer to Automatic curb
monitor, page 52
>After the engine is started, calls up
the last selected driving program for
each shifting mode, refer to page 73.

Starting the engine and driving off
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
drive off immediately at a moderate
engine speed.<
Do not allow the engine to run in
enclosed spaces. Otherwise,
breathing the exhaust fumes can lead
to unconsciousness and death. The
exhaust gases contain carbon monox-
ide, an odorless and colorless, but
highly toxic gas. Do not leave the vehi-
cle unattended with the engine running.
An unattended vehicle with a running
engine represents a safety hazard.<
If the engine does not start on the first
attempt – if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures
below about 57/–156 and at high
altitudes above 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period, but no longer than
20 seconds.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<
When driving, standing at idle or
parking the vehicle, take care to
avoid contact between the hot exhaust
system and flammable materials –
grass, hay, leaves, etc. Such contact
could lead to a fire, resulting in serious
personal injury and property damage.<

With the engine running, the gear
indicator in the SMG Drivelogic
display flashes to indicate that a driving
position is engaged with the driver's
door open or if the hood is not closed
properly, refer to page 71.
If neither the pedals, the shift paddles,
nor the selector lever are actuated, then
the gearbox is automatically taken out
of gear after approx. four seconds. It
will then be necessary to move the
selector lever back to position N before
engaging the desired driving position.
Driving off is not possible with the hood
open.<

67
Before exiting the vehicle with the
engine running, move the selector
lever into position N and apply the
parking brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a safety hazard.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.

Switching off the engine
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not provide ade-
quate resistance to rolling.<
Manual transmissionTurn the ignition key to position 1 or 0.Sequential M gearbox with
DrivelogicIf you turn the ignition key to position 1
or 0 with the selector lever in the for-
ward or reverse position, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in
position N, a warning tone and the
flashing gear indicator in the SMG
Drivelogic display remind you that no
gear is engaged to secure the vehicle
against rolling.
The warning stops after approx. ten
seconds. If you move the selector lever
into a forward or reverse position dur-
ing this time, a gear is automatically
engaged.
Parking brakeThe parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels.To engageThe detent engages automatically, and
the indicator lamp in the instrument
cluster comes on when the ignition key
is in position 2, refer to page 18.To releasePull up slightly on the lever, press the
button and lower the lever.

it is not necessary to manually engage
position N.S – Sequential modeIn the sequential mode all forward
gears are to be shifted by the driver.
To switch from automated to sequential
mode:
>Tap the selector lever to the right
toward 'S' or
>change gears with the selector lever
or the shift paddles on the steering
wheel.
You do not need to reduce the throttle
for shifting.

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward in the '+' direction
>To downshift, push the selector lever
in the '–' direction.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the
SMG Drivelogic anticipates your
actions in the sequential mode:
>Upshifts and downshifts are only exe-
cuted at appropriate combinations of
engine rpm and vehicle speed. For
instance, downshifts that would
result in excessive engine speed are
not executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>As speed diminishes, the gearbox
downshifts automatically, without you
taking any action, just before the
vehicle slows to below each gear's
minimum speed.D - Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are shifted automatically.To switch from sequential to automated
mode: tap the selector lever to the right
toward 'D'. Watch the display in the
instrument cluster, refer to page 71.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. The gearbox
now downshifts depending on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.
