The current driving speed is stored as a
desired speed and briefly displayed in the
instrument cluster, see below.
1 Desired speed store and increase
Press the lever forward:
The system adopts and stores your current
speed as a desired speed. The speedome-
ter indicates this speed.
Subsequently pressing forward increases
the desired speed to the next 5-mile place/
10 km/h.
Each time the lever is pressed forward
again, the desired speed is increased by
another 5 mph/10 km/h until a maximum of
110 mph/180 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
If the system cannot be activated, the
display ACC --- mph/km/h briefly
appears in the instrument cluster. The sys-
tem may have been automatically deacti-
vated, refer to Deactivate system, or a mal-
function has occurred.
To call up Check Control messages, refer
to page 68.<
2 Desired speed store and decrease
Pull back the lever:
The current driving speed is rounded off to
the next 5-mile place/10 km/h, displayed
and stored.
Each time the lever is pulled back again,
the desired speed is decreased by another
5 mph/10 km/h until the minimum speed of
20 mph/30 km/h is reached. The speed
then displayed is stored and reached on a
clear road.
3 Deactivate system
Press the lever up or down while the sys-
tem is active. The displays in the instrument
cluster disappear. You can use the system
again as required.
In addition, the system is deactivated auto-
matically:
>When you apply pressure to the brake
pedal
>When you select the automatic trans-
mission's/SMG's neutral range N
>With the manual transmission idling
>When you deactivate the DSC Dynamic
Stability Control
>When you actuate the parking brake
during driving
>When the system reduces the speed to
below 20 mph/30 km/h due to a traffic
situation.
The system deactivates automatically
when the speed is set to below
20 mph/30 km/h. A gong sounds and a
message appears on the Control Display.
The active intervention of the driver is
required.<
When you switch off the ignition, the stored
desired speed is deleted.

Things to know about active cruise control
As with conventional cruise control
systems, active cruise control in no
way diminishes or substitutes for the
driverÕs own personal responsibility, alert-
ness and awareness in adjusting speed,
braking or otherwise controlling the vehi-
cle. The driver should decide when to use
the system on the basis of road, traffic, vis-
ibility, and weather conditions. Active
cruise control is intended for use on high-
way-type roadways where traffic is moving
relatively smoothly. Do not use this system
in city driving; heavy traffic such as during rush hour; on curvy, winding roads, slip-
pery roads or roads with sharp curves such
as highway off-ramps; during inclement
weather such as snow, strong rain or fog;
or when entering interchanges, service/
parking areas or toll booths. It is also
important to regulate your vehicle's speed
and distance setting within applicable legal
limits. Always be ready to take action or
apply the brakes if necessary, especially
when the system is actively following a
vehicle in front of you.<

Driving
64 choose to overcome the deceleration by
briefly pressing the accelerator pedal.
Driver interventions
Anytime the driver presses down on
the accelerator pedal, any automatic
braking action by the system is interrupted
until the pedal is fully released. After doing
this, release the accelerator and the system
again controls your cruising speed and dis-
tance setting. While driving with activated
system, resting your foot on the accelerator
pedal will cause the system not to brake
even if necessary. Be certain that floormats
or other objects on the vehicle floor do not
interfere with movement of the accelerator
pedal.<
While active cruise control is capable
of braking your vehicle automatically
when you approach a slower vehicle
ahead, it is important to be aware that the
ability of the system to apply the brakes is
also limited, if you are driving down a steep
grade or when you reduce your desired
speed sharply. The system cannot stop
your vehicle. It uses only a portion of brak-
ing system capacity and does not utilize the
full capacity of the vehicle braking system.
Therefore, the system cannot decrease
your speed for large differences in speed
between your vehicle and the vehicle
ahead. Examples: during emergency brak-
ing, when you approach a vehicle traveling
at a much lower speed than your own
speed such as approaching a toll booth or
when a much slower vehicle cuts in front of
you at close range.<
Whenever active cruise control
recognizes a situation that
requires driver braking because
the system capacity has been
reached or has been exceeded,
the system alerts the driver by flashing this
symbol in the instrument cluster and
sounding a signal.
Swerving vehicles
When a vehicle moves from an adjacent
lane into your lane, active cruise control will
not recognize this vehicle until it is fully in
your lane ahead of your vehicle.
Malfunctions
If there is a malfunction, the indica-
tor lamp symbol is displayed in the
instrument cluster. Please note any
supplementary information that appears on
the Control Display.
The build-up of foreign material, e.g.,
snow, ice, dirt, road debris, etc., can lead
to reduced detection performance of active
cruise control. You should check the sen-
sor under the front bumper and clean it as
necessary prior to driving your vehicle. If
the sensor becomes covered by foreign
material or has a malfunction, it is possible
that the sensor will no longer be able to
detect vehicles in front of you. After the
system recognizes that the sensor is no
longer functional, a message is displayed
on the Control Display and an acoustic sig-
nal is emitted.

Fuel tank capacity: approx. 18.5 gallons/
70 liters, of which approx. 2.1 gallons/
8 liters reserve. You can find information on
Refueling on page 168.
If the tilt of the vehicle varies for a longer
period, when you are driving in mountain-
ous areas, for example, the indicator may
fluctuate slightly.
Refuel well before the tank is empty,
as otherwise engine functions will not
be ensured and damage can occur if you
drive down to the last drop.<

the BC button in the turn signal indicator
lever to call up computer information in the
instrument cluster.
A new function appears each time you
press the BC button briefly.
Displays in the instrument cluster
The display sequence:
>Cruising range
>Average speed
>Average fuel consumption.
Cruising range
Displays the estimated cruising range
available with the remaining fuel. The sys-
tem calculates the cruising range based on
operating conditions and the amount of fuel
remaining in the tank. The basis for the cal-
culations is the average fuel consumption
over the preceding 20 miles/30 km.
Always refuel as soon as possible
once your cruising range falls to
below 30 miles/50 km, as otherwise engine functions are not ensured and damage can
occur.<
Refueling is only registered by the com-
puter for fuel amounts above approx.
1.3 gallons/5 liters.
Average fuel consumption
The average fuel consumption is calculated
for the time during which the engine is run-
ning.
You can use the Control Display to view
your fuel consumption rate over two differ-
ent distances, refer to Computer or Trip
computer.
To reset the average fuel consumption to
zero: press the BC button in the turn signal
indicator lever for approx. 2 seconds.
Average speed
Periods with the vehicle parked and the
engine switched off are not included in the
calculations of average speed.
To reset the average speed to zero: press
the BC button in the turn signal indicator
lever for approx. 2 seconds.

CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
EBV Electronic Brake Force
Distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
In case of malfunction
If the brake system warning lamp
lights up in red, appearing together
with the yellow indicator lamps for
ABS and DSC:
The driving stability control has
failed.
If all three lamps light up yellow:
Fault in the driving stability control.
The EBV electronic brake-force distribution
is active.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
If a message appears on the Control Dis-
play, please note the supplementary infor-
mation.

Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control, refer to
page 79.
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction. The
system recognizes any tendency for the
vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
Indicator lamps
The indicator lamp in the instrument
cluster goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC is regulating the drive and braking
forces.
If the indicator lamp lights up permanently:
DSC has been switched off using the but-
ton.
If the indicator lamp and the brake
warning lamp light up permanently:
Malfunction in DSC, DTC and DBC.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.
