DrivelogicDrivelogic makes various driving pro-
grams available to you.
Press the Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 71.
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
In the sequential mode you can choose
from six driving programs ranging from
balanced, dynamic driving – 1 – to
sporty, puristic driving – 6. The sporty,
puristic driving program can only be
activated with the Dynamic Stability
Control (DSC) deactivated, refer to
page 86.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Following each change between the
sequential and the automated mode,
the last driving program selected in the
respective mode is active. Exception:
instead of the last selected sequential
driving program 6, program 5 is acti-
vated only after the engine has been
started again.
Your vehicle is set so that when
the engine is started, the last
selected driving program saved in your
key is activated for each shifting
mode.<
Gradient assistanceThe gradient assistance enables start-
ing off on grades with virtually no roll-
back. It can be activated in the sequen-
tial and automated mode with the vehi-
cle stopped and can be used for both
forward and reverse driving.
The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
1. Depress footbrake with vehicle
stopped
2. Activate the gradient assistance by
pulling the left paddle for at least
0.5 seconds. An increase in the
engine speed indicates that the gra-
dient assistance is activated
Briefly pulling the left paddle again
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within two seconds.
The gradient assistance must be reacti-
vated before each use.

Indicator lamp
The gearbox indicator lamp in
the instrument cluster goes out
after the engine is started.
>If it does not go out, or if it lights up
during driving, a malfunction has
occurred. The available functions
may be limited under certain circum-
stances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the opti-
mum shifting point shortly before the
maximum engine speed is reached.
1. When the maximum engine speed is
approached, yellow indicator fields –
shift lights – in the tachometer light
up consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.
Tire replacement, snow chainsFollowing a tire or wheel change and
after mounting or removing snow
chains, the slip recognition of the
SMG Drivelogic must become familiar
with the changed condition.
Reinitialize the system afterwards:
1. Move the selector lever into
position N on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
two seconds.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.

Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. Always use a wind-
shield washer antifreeze in cold
weather. Refer to page 126.
Do not use the washers when the reser-
voir is empty. This could cause damage
to the washer pump.<
The system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
When the vehicle's lighting system is
switched on, the headlamps will also be
cleaned at reasonable intervals.Windshield washer nozzlesThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.
Cruise controlYou can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph / 30 km/h.
The cruise control is available whenever
the engine is running and the system
has been activated.To activate the systemIn ignition key position 2:
Press the button in the steering wheel.
The indicator lamp in the instrument
cluster comes on, refer to page 20. You
can now use the cruise control.

ing roads, when high traffic den-
sity prevents driving at a constant
speed, or when the road surface is slick
– snow, rain, ice – or loose – rocks or
gravel, sand. until the indicator lamp in the instru-
ment cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.

Press and hold button +:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
maintains and stores the current speed.
If on a downhill gradient the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button – briefly:
If you are already driving with activated

Fuel gaugeOnce the indicator lamp stays on con-
tinuously, there are still approx.
2 gallons/8 liters of fuel in the fuel tank.
Fuel tank capacity approx. 16.6 gal./
63 liters.
If the tilt of the vehicle varies – when
you are driving in mountainous areas,
for example – the needle may fluctuate
slightly.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.

appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a '–' in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
