signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active Cruise
Control cannot automatically restore the dis-
tance to the vehicle ahead.
This indicator does not release you from your
responsibility to adapt your desired speed and
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow.
The prerequisites for operating
Active Cruise Control are not met,
e.g. as a result of ABS or DSC
interventions. Active Cruise Con-
trol is deactivated. Yo u can reactivate the sys-
tem, if desired, by brie fly pressing or pulling the
lever when road and traffi c conditions permit. It
is not possible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a re sult of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bump er, see arrow. Be sure
t o u se p a r t i c ul a r c a r e w h e n r e m o v i n g a ny l a y e r s

System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle, or stationary object ahead
of you, for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potentia l traffic such as a rider
on horseback. The system may also not detect
smaller moving objects such as motorcycles or
bicycles. Be especially alert when encountering
any of these situations as the system will nei-
ther automatically brake, nor provide a warning
to you. Also, be aware that every decrease in
the distance setting allows your vehicle to come
closer to a vehicle in front of you and requires a
heightened amount of alertness. <
Active Cruise Control is not and must not
be used as a collisio n avoidance/warning
system. <
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactiva te the system when
you pull into an exit lane for a highway off-
ramp. < Also, vehicles travelin
g in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
While Active Cruise Co ntrol 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 sys-
tem to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full ca pacity 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: 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. <
Active Cruise Control ca n only decelerate the
vehicle to approx. 20 mph or 30 km/h.

Tachometer
Never force the engine speed up into the red
warning field, see arrow. In this range, the fuel
supply is interrupted to protect the engine.
Engine oil temperature
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 210
7/100 6 and approx. 300 7/
150 6.
If the engine oil temperature is too high, a warn-
ing lamp lights up in the instrument cluster.
Fuel gauge
Fuel tank capacity: approx. 16.1 US gal/
61 liters.
You can find information on refueling on
page 175.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone of approx. 2.1 US gal/8 liters, the indicator
lamp and the cruising range for the remaining
amount of fuel light up briefly. The indicator
lamp remains permanentl y on when the remain-
ing range is less than approx. 30 miles/50 km.
With a dynamic driving style, e.g. rapid corner-
ing, engine functions are not always assured.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur. <

Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys-
tems monitored. This type of Check Control
message includes indicator and warning lamps
in the instrument cluster and, in some cases, an
acoustic signal.
Indicator and warning lamps can light up in a
variety of combinations and colors.
Several of the lamps are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.
Indicates that Check Control messages have
been stored. These Check Control messages
can be viewed again later, refer to page88.
What to do in case of a malfunction
The meaning of each lamp in the event of a mal-
function and tips on how to respond are listed
starting on page220.
Hiding Check Control messages
Press the button on the turn signal/high beam
lever.
>Some Check Control messages are dis-
played continuously an d remain visible until
the malfunction has been rectified. If several
malfunctions occur at once, the messages
are displayed consecutively.
These messages can be hidden for approx.
8 seconds. After this, they are displayed
again automatically.
> Other Check Control messages are hidden
automatically after approx. 20 seconds.
They are stored and can be displayed again
later.

tions will be given of some equipment that may

cle, for example due to
the special options or national-market version

functions and systems.
Park Distance Control PDC
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals warn you of
the presence of an object in front of or behind
your vehicle. To meas ure the distance, there
are four ultrasonic sensors in either bumper.
An acoustic warning sounds when an object is
less than approx. 24 in/60 cm from the front
sensors and rear corner sensors or less than
approx. 5 ft/1.50 m from the rear center sen-
sors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually th e case when parking.
Avoid approaching an object at high speed; oth-
erwise, physical circumstances may lead to the
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. one
second when you shift in to reverse or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above
approx. 20 mph/approx. 30 km/h, the system
switches off and the LED goes out.
Switching on manually
When parking in the forward direction, the sen-
sors must be switched on manually to enable
them to signal an approach to an object in front
of or behind the vehicle.
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. For exam-
ple, if an object is detected behind the vehicle,
the signal tone sounds from the rear. As the dis-
tance between vehicle an d object decreases,
the intervals betwee n the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is in terrupted after approx.
3seconds
> If you remain in front of an object that has
been detected by only one of the corner
sensors
> If you are driving parallel to a wall.

Malfunction
The warning lamp lights up. PDC is
malfunctioning. Have the system
checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to op erate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 1 ft/30 cm.
Manual operation
The LED above the button also flashes.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind sp ot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or af ter a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously; otherwise, there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage. <
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page 134.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressu re on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical lim its by reducing engine
output and through braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taki ng risks, as this could
result in an accident. <

4.Press button 2 for approx. 5 seconds, until
the reading shown below is displayed:
5. Start driving.
Initialization is completed while the car is on
the move, without any feedback.
The initialization is completed during driv-
ing, which can be inte rrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. <
Indication of a flat tire
The warning lamps light up in yellow
and red. In addition, an acoustic sig-
nal sounds. There is a flat tire or a
major loss in tire pressure.
1. Reduce speed and stop the vehicle with
caution. Avoid sudden braking and steering
maneuvers.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a flat tire is reported, the Dynamic Stabil-
ity Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
With a damaged tire, is possible to continue
driving at speeds of up to 50 mph/80 km/h.
When driving with a damaged tire:
1. Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph/80 km/h. 3.
At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure in all four tires is cor-
rect, the Flat Tire Monitor might not have
been initialized. The system must then be
initialized.
Possible driving distance with complete loss of
tire pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving.
With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics ch ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously an d do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change , e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change. <
Vibrations or loud noises while driving can
indicate final failure of the tire. Reduce
your speed and bring the vehicle to a stop; oth-
erwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <
