safety precautions
2. Ensure that the convertible top com-
partment panel in the luggage com-
partment is folded down, see
page 37; otherwise, it will not be
possible to open the convertible top
3. Ensure that the luggage compart-
ment lid is closed
4. Maintain pressure on the corre-
sponding button for the convertible
top operation.
The luggage compartment lid can-
not be opened while the convert-
ible top is in motion.<
While the convertible top is in
motion, the rear window will move

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle 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. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system then relies on a bilateral
data exchange to identify the individual
user and executes the selected settings
whenever the remote control unit is
used to disengage the door locks.
Distinguishing between keysColor-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYour BMW center can provide you with
details on the capabilities of the Vehicle
Memory and Key Memory systems.
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 as acknowledgment
when locking or unlocking your vehi-
cle, refer to pages 31, 33
>Activates/deactivates the 'Follow me
home' function, refer to page 97
>Activates/deactivates daytime driv-
ing lamps, refer to page 97
>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 92
>Switches on rear window defroster
automatically, refer to
pages 104, 109
>Activates/deactivates various alarm
system functions, refer to page 39
>After giving an ice warning, the
onboard computer display returns to
the previous setting, refer to page 90.
Examples for Key Memory:
>Unlocks driver's door first, then the
vehicle's remaining locks, refer to
page 33
>Locks the vehicle automatically after
you start off, refer to page 34
>Automatically adjusts the driver's
seat to the personal programmed
settings when the vehicle is
unlocked, refer to page 57
>Automatic tilting of the passenger-
side mirror, refer to Automatic curb
monitor, page 58.

3Start engineSteering lockedThe key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
you hear the lock engage.
If the key is not removed, an acoustic
signal sounds when the driver door is
opened.
Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position P until the engine is running,
ignition key position 2.
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 or removed until
the selector lever is in position P.<
Vehicles with manual transmis-
sion:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not
depressed.<
Steering unlockedYou will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation.
Starting the engine
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.
When driving, standing at idle or park-
ing the vehicle, take care to avoid con-
tact 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.<
Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.<

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 extremely low tempera-
tures below approx. +57/–156 and at
altitudes over 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
>Press the accelerator pedal halfway
down while engaging the starter.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged can damage the catalytic con-
verter.<
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.Manual transmission1. Engage the parking brake
2. Gearshift lever in idling position
3. Start the engine.Automatic transmission1. Depress footbrake
2. Place the selector lever in position P
or N
3. Start the engine.
To prevent the vehicle from start-
ing off on its own, always move
the selector lever to position P and
engage the parking brake before leav-
ing your vehicle with the engine run-
ning.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard. 2. Move selector lever into position N
3. Start the engine.
If the engine does not start, reen-
gage the gear last selected, refer
to the gear indicator in the display, and
move the selector lever into neutral
position N again.
The gearbox is automatically taken out
of gear if the driver's door is opened
while the engine is running and the
driver does not actuate the pedals, the
shift paddles or the selector lever. This
is accompanied by a warning tone and
the flashing gear indicator. The gear
display N appears in the instrument
cluster.<
Before exiting the vehicle with the
engine running, move the selector
lever into position N and apply the park-
ing brake.

Sequential manual gearbox SMG*The conceptThe sequential manual gearbox SMG is
an automated manual gearbox with
which clutching and shifting is assumed
by an electro-hydraulic system.
The SMG is operated via the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Sequential mode: manual mode
>Drive mode: automatic operation
>Ability to choose between two differ-
ent driving programs: Standard,
Sport
>Operating safety through protection
against misshifting
>Automatic upshifts and downshifts in
the drive mode
>Automatic downshifts at minimum
engine rpm
>Kickdown function in the drive mode.
>Acceleration assistant, refer to
page 78.
Selector lever positionsThe current selector lever position is
indicated by a light-emitting diode in
the center console.
R: Reverse
N: Neutral
Position for forward driving with one-
touch functions:
Sequential mode
+: manual upshifts
—: manual downshifts
D: drive mode.
The SMG is ready for operation in igni-
tion key position 2.
The gearbox is automatically
placed in neutral gear if the
driver's door is opened while the engine
is running and the driver does not actu-
ate the pedals, the shift paddles or the
selector lever.
This is accompanied by an acoustic
signal and the flashing gear indicator.
The gear display N appears in the
instrument cluster.
A driving position can only be engaged
when the driver's door is closed.
When the vehicle is unlocked, a buzzer
in the area of the transmission indicates
that the system is ready for operation.<
ShiftlockWhen the car is at a standstill, a safety
function requires you to depress the
brake pedal if you want to move the
selector lever from the neutral
position N to a driving position.Driving precautions
Use enough acceleration to pull
away speedily when moving off on
an uphill gradient. Never try to prevent
the car from rolling back on an uphill
gradient by depressing the accelerator
pedal; always apply the handbrake.
Otherwise you could overheat the SMG
gearbox.<

RReverseSelect only when the vehicle is station-
ary.NNeutralAlways engage before starting the
engine, refer to Starting the engine on
page 72.Sequential modeEach time the engine is started, the
sequential mode is activated as soon as
you move the selector lever into the for-
ward driving position while the brake is
depressed.
The gears are shifted via the shift pad-
dles or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.DDrive modeIn the drive mode all forward gears are
shifted automatically.
To switch from sequential to drive
mode: tap the selector lever to the right
toward D.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely: kickdown.To switch back to sequential mode: tap
the selector lever again to the right
toward D or change the current gear via
the shift paddles or the selector lever.
KickdownYou can achieve maximum acceleration
using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
Shifting gearsWith the selector lever:
>To upshift, tap the selector lever
toward +
>To downshift, tap the lever toward —.
With the shift paddles on the steering
wheel:
>To upshift, pull one of the shift pad-
dles
>To downshift, push the paddle.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations, the SMG in
the sequential mode assists you:
>Upshifts and downshifts are only exe-
cuted at appopriate combinations of
engine rpm and vehicle speed. For

instance, downshifts that would
result in excessive engine speed can-
not be executed.
>When you brake the car to a stop, the
transmission automatically shifts
down to first gear
>As speed diminishes the transmission
will shift down automatically, without
any action on your part, just before
the vehicle slows to below each
gear's minimum speed.

If the indicator lamp comes on,
there is a malfunction in the
transmission system.
All selector lever positions can still be
engaged, but in the forward driving
positions only certain gears are actually
available when the vehicle is driven.
Avoid extreme loads and proceed to
the nearest BMW center.
For information on jump-starting and
towing the vehicle, refer to page 159.Warning toneAn acoustic signal sounds if the SMG
gearbox overheats; if possible you
