Servotronic*
The concept
The Servotronic varies the steering force
required to turn the wheels relative to the vehi-
cle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
Malfunction
Malfunctions are displayed via Check Control,
refer to page80.
Brake Force Display
On the left: normal braking.
On the right: sharp braking.

Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left side of the button to
reduce the air volume. Press the
right side of the button to increase
it.
The air volume may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Automatic recirculated-air control
AUC/Recirculated-air mode
You can respond to unpleasant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated-air mode and increase the air
volume, if necessary. Make sure that air can
flow onto the windshield.
The recirculated-air mode should not be
used over an extended period of time;
otherwise, the air quality inside the car will dete-
riorate continuously.<
Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using a
button
on the steering wheel, refer to page11.
ALL program
Press the button.
The current temperature setting
on the driver's side is transferred to
the front passenger side.
If the temperature setting on the driver's side is
changed, the temperature on the front passen-
ger side is changed as well.
The program is switched off when the setting is
adjusted on the front passenger side or the but-
ton is pressed again.
Defrosting windows and removing
condensation
Press the button.
Quickly removes ice and conden-
sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
Switching cooling function on/off
The passenger compartment can only be
cooled while the engine is running.
Press the button.
The air is cooled and dehumidified
and – depending on the tempera-
ture setting – warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
Rear window defroster
Press the button.
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's equipment, the
upper wires serve as an antenna and are not
part of the rear window defroster.

Calibrating the digital compass
The digital compass must be calibrated in the
following situations:
>An incorrect compass direction is shown.
>The compass direction shown does not
change although the direction of travel
does.
>Not all compass directions are shown.
Procedure
1.Make sure that no large metal objects or
overhead power lines are in the vicinity of
your vehicle and that you have enough
space to drive in a circle.
2.Set the currently valid compass zone.
3.Press the adjustment button for approx. 6-7
seconds to call up C. Then drive in at least
one full circle at a speed of no more than
4mph or 7km/h.
If calibration is successful, the display
changes from C to a compass direction.
Setting right-hand/left-hand steering
Your digital compass is factory-set to right-
hand or left-hand steering, in accordance with
your vehicle.
Set the language
You can set the language of the display:
Press the adjustment button for approx. 12-13
seconds. Briefly press the adjustment button
again to switch between English, "E", and Ger-
man, "O".
The setting is automatically saved after approx.
10 seconds.
Roller sun blinds*
Rear window blind
Tap the button in the center console to raise or
lower the roller sun blind.
Roller sun blinds for rear side windows
Pull loop of roller sun blind and hook onto
bracket.
Do not open the window when the roller
sun blind has been pulled up; otherwise,
there is a risk of damage at high speeds that
may result in personal injury.<
Glove compartment
Opening
Pull the handle.
The light in the glove compartment comes on.
To prevent injury in the event of an acci-
dent while the vehicle is being driven,
close the glove compartment immediately after
use.<
Closing
Fold the cover up.

Things to remember when driving
124
Diesel particulate filter*
The diesel particulate filter collects soot parti-
cles and burns them periodically at high tem-
peratures. This cleaning process takes several
minutes. During cleaning, you may notice that
the engine temporarily runs less smoothly and
that a somewhat higher engine speed is neces-
sary to achieve the accustomed performance.
Also, noises may be heard and a slight amount
of smoke may emerge from the exhaust, even
for a short period after the engine is switched
off.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page222.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise, greater
clutch wear will result.<
For more information about the drive-off
assistant, refer to page87.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page59.
Never drive with the clutch held down,
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired.<

Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page79.
>Radio
In some cases, stations may have to be
stored again, refer to page154.
>Navigation system
Operability must be waited for, refer to
page130.
>Glass roof
It may happen that the roof can only be
raised. The system must be initialized.
Please contact your BMW center.
>Panorama glass roof
It may happen that the roof can only be
raised. The system must be initialized.
Please contact your BMW center.
>Seat and mirror memory
The positions must be stored again, refer to
page46.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page110.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page92.
>xDrive
The system automatically initializes itself
during a trip. Indicator lamps light up during
this time. If the lamps do not go out during
the current trip, have the system checked.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating; oth-
erwise, this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<
Open the cover in the glove compartment and
remove it.
Plastic tweezers are located on the distributor
box.
See the rear of the cover for information on fuse
assignment.
Spare fuses are available from your BMW cen-
ter.

Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
Sedan: it is stored in the onboard vehicle tool kit
underneath the cover on the right-hand side of
the cargo area, refer to page237.
Sports Wagon: it is stored in the onboard vehi-
cle tool kit underneath the cover on the left-
hand side of the cargo area, refer to page237.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing on paved roads only. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting. Otherwise, the
tow fitting and the vehicle could be damaged.<
Access to screw thread
Release the cover panel in the bumper:
Press on the upper part of the cover panel.
Front
RearBeing towed
Make sure that the ignition is switched on,
refer to page55; otherwise, the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort. Active
steering is not active and it will be necessary to
turn the steering wheel further.<
Manual transmission
Gearshift lever in neutral position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page58.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km; otherwise, the automatic
transmission may be damaged.<
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise, dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle; otherwise, it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
