Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning whenever the ignition key is
turned. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this below.

Red: stop immediately

Battery charge current



l

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
If the drive belt is defective, do not
continue driving, as the engine
could sustain serious damage from
overheating. If the drive belt is defec-
tive, increased steering effort is also
required.

<


Engine oil pressure


l

Stop the vehicle immediately
and switch off engine. Check
the engine oil level and top up as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

Flat Tire Monitor
l
In addition, an acoustic signal
sounds: a tire failure has
occurred. Reduce vehicle speed imme-
diately to stop the vehicle. Avoid hard
brake applications. As you steer the
vehicle, use caution and avoid overcor-
recting.

For your safety, it is only possible to
engage a driving position with the
vehicle stopped approx. 2 seconds
after engaging the position 0 with the
footbrake depressed (shift-lock func-
tion).
It is not necessary to hold the footbrake
depressed until starting off, as the
vehicle does not move forward with the
driving position engaged.Starting engine and driving offTo start the engine:
1. Depress footbrake
2. Move selector lever into position 0
3. Turn the ignition key to position 3,
refer to page 56.
To drive off:
1. Depress footbrake
2. Engage a driving position
3. Release footbrake and slowly
depress accelerator pedal.
With the engine running, the gear
indicator in the instrument cluster
flashes to indicate that a driving posi-
tion is engaged with the driver's door
open or if the hood is not closed prop-
erly, refer to page 61.
If none of the pedals is actuated, then
the gearbox is automatically taken out
of gear after approx. 4 seconds.
Then the desired direction of travel
must be selected again with the
selector lever in position 0.<
Starting off is not possible with the
hood open.<
Before exiting the vehicle with the
engine running, move the selector
lever into position 0 and apply the
parking brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a potential safety hazard. or 0 with the selector lever in the
forward or reverse position, a gear
automatically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in position 0,
a gong and the flashing gear indicator
in the SMG display remind you that the
vehicle is not secured against rolling.

OverviewControlsMaintenanceRepairsDataIndex
Sequential M gearbox* SMG IIThe warning stops after approx.
10 seconds. If you move the selector
lever into a forward or reverse position
during this time, a gear is automatically
engaged.
The SMG II has no park position
for securing the vehicle against
rolling.
The ignition key can be removed in any
selector lever position.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently
secure the vehicle against rolling.<
Display in instrument clusterThe selector lever position, currently
engaged gear and selected driving
program are displayed in the instrument
cluster.
1 Engaged gear
2 Selected driving program
(corresponds to the number of illumi-
nated fields), refer to page 64
3 Tapping the selector lever to the right
switches over into the displayed shift
mode
4 "A" indicates an activated automated
mode.
R Ð Reverse positionOnly engage with the vehicle stopped
or at low speed, e.g. for "rocking free"
in deep snow.0 Ð Position 0Always engage before starting the
engine.
If the driving situation requires, e.g.
when downshifting on slippery roads,
the SMG II automatically disengages
and reengages the clutch, i.e. it is not
necessary to manually engage
position 0. S Ð Sequential modeIn the sequential mode all forward
gears are to be shifted by the driver.
Changeover 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.

62n
Sequential M gearbox* SMG IIShifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right
paddle "+"
>To downshift, briefly pull the left
paddle "Ð."
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW
center.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward "+"
>To downshift, push the selector lever
forward "Ð".
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually down-
shifting.
In the following situations the SMG II
helps you "think" in the sequential
mode:
>Upshifts and downshifts are only
executed when the new gear will
provide a suitable combination of
vehicle and engine speed, i.e., down-
shifts that would cause the engine to
overrev will not be 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
>When the speed is reduced, the
gearbox is automatically down-
shifted shortly before a gear-depen-
dent minimum speed is reached
without you taking any action.
A Ð 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 automatically shifted.
Changeover from sequential to auto-
mated mode: tap the selector lever to
the right toward "A." Watch the display
in the instrument cluster, refer to
page 61.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely (kick-down). The gearbox
now downshifts in dependence 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.

Sequential M gearbox* SMG IIDrivelogicDrivelogic makes various driving
programs available to you.
Press Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 61.
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 to sporty, puristic
driving. The sporty, puristic driving
program can only be activated with the
Dynamic Stability Control (DSC) deacti-
vated, refer to page 76.
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 activated 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
starting off on grades with virtually no
roll-back. It can be activated in the
sequential and automated mode with
the vehicle stopped and can be used
for both forward and reverse driving.
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
gradient assistance is activated.
Pulling the left paddle again briefly
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within 2 seconds.

76n
Dynamic Stability Control (DSC)

The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it also recognizes
unstable driving conditions such as
under- or oversteering on curves, and
helps the vehicle remain on a steady
course by using the engine and brake
system to intervene at the different
wheels Ð doing only what it can within
the laws of physics, of course.
The DSC is operational every time you
start the engine. The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stability.
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
>Indicator lamp flashes: the DSC is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the DSC has been
deactivated via the button or there is
a malfunction. You can continue to
drive the vehicle normally, but
without DSC. Please consult your
BMW center for repairs.

Flat Tire Monitor
M Engine dynamics control
In the event of a flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of a flat tire with
ensuing loss in pressure. In addition, an
acoustic signal is sounded. To come to
an immediate stop, reduce speed, while
avoiding any sudden, jerky braking or
steering maneuvers.
Fix the flat tire using the M Mobility
system, refer to page 126.
Reset the indicator lamp: the red indi-
cator lamp has to be switched off
manually after putting on a new wheel.
At this point, hold the Flat Tire Monitor
button down until the indicator lamp
goes out. Reinitialize the system after-
ward.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check the tire inflation pressure
on a regular basis and correct if
necessary, refer to page 24.
Under certain circumstances, there
may be false warnings or a delayed
detection of losses in pressure when
driving on snow-covered or slippery
road surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.
The system (sport-mode identification)
will cause the engine to respond spon-
taneously to the motion of the acceler-
ator pedal. Activating/deactivating
sport-mode identificationActivating: with the key in ignition key
position 2, press the sport button. The
indicator lamp will light up.
The vehicle may gain speed
without any additional pressure on
the accelerator pedal when the system
is activated.<
Deactivating: press the sport button
again; the indicator lamp will go out.
The sporty-comfortable mode is deacti-
vated every time the engine is started.

Automatic climate control
*
Tips for pleasant drivingUse the automatic system (switch on
AUTO button 7). Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
You vehicle is set in such a
manner that, when you unlock the
vehicle with the remote control of your
personal key, your own personalized
setting for the automatic climate control
is initiated. The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and Ð
in addition to that Ð adapts the temper-
ature to external influences (summer,
winter) to meet preferences you can
specify.
Individual air distribution
You can cancel the AUTO
program by selecting specific
distribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic air supply control
remains in operation. The system
directs air to the windows , the upper
body and into the footwells . You
can reactivate the automatic air supply
by pressing the AUTO button.
Temperature
The displayed temperatures are
reference values for the interior
temperature. We recommend 727
(+226) as a comfortable setting, even
if the air conditioner is on. When you
start the vehicle, the system ensures
that the selected temperature is
reached as quickly as possible. It then
maintains this temperature, regardless
of the season.
Air supply (blower)
By pressing the left or right side
of the button, you can vary the
air supply. This deactivates the auto-
matic air supply Ð the AUTO display
disappears from the panel. Neverthe-
less, the automatic air distribution
remains unchanged. You can reactivate
the automatic air supply by pressing the
AUTO button.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.
To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and side windows.
