Technology for driving comfort and safety
Controls
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 spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limit s 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 after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC
signal. Therefore, always drive cautiously; oth-
erwise, there is a risk of personal injury or prop-
erty 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.
Antilock Brake System ABS
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 126.
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 exploi ts all of the benefits
provided 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 aw ay 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 limits by reducing engine
output and through brakin g 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The laws of physics cannot be repealed,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 no t reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident. <
Deactivating DSC
Press the button for at least 3 seconds until the
indicator lamp for DSC OFF lights up and DSC
OFF is displayed in the instrument cluster.
Dynamic Traction Cont rol DTC and DSC have
been simultaneously de activated. Stabilizing
and drive-output promoting actions are no
longer executed.

Replacing components
Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehi
cle, for example due to
the special options or national-market version
selected. This also app lies to safety related
functions and systems.
Onboard vehicle tool kit
The onboard vehicle tool kit is stored below the
floor mat in the trunk.
Wiper blades
1. Fold out the wiper arm and hold it.
2. Press together the locking spring, arrows 1,
and fold out the wiper blade, arrow 2.
3. Take the wiper blade out of the catch mech-
anism, pulling the blade toward the front.
To avoid damage, make sure that the
wiper arms are against the windshield
before you open the hood. <
Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or some thing similar, or hold
the bulb by its base. <
Replacement bulb sets are available at your
BMW center.
Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns. <
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer. <
To replace lamps not described here,
please contact your BMW center. <
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light sources for many
of the controls and displays in your vehicle.
These light-emitting diodes, which operate
using a concept similar to that applied in con-
ventional lasers, are officially designated as
Class 1 light-emitting diodes.
Do not remove the co vers or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation of the retina. <

Giving and receiving assistance
Mobility
Use only the tow fitting provided with the
vehicle and screw it a
ll 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

Being towed
Make sure that the ignition is switched on,
refer to page61; otherwise, the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable. There is
no power assist while the engine is off. Thus,
braking and steering will require increased
effort. Active steering is not active and it will be
necessary to tu rn the steering wheel further. <
Manual transmission
Gearshift lever in neutral position.
Automatic transmission
Selector lever in position N.
Changing selector lever position, refer to
page 64.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km; otherwise, the automatic
transmission may be damaged. <
Sport automatic transmission with
double clutch
Make sure that the parking lock P is not
engaged; otherwise, the rear wheels are
immobilized.
When using the car wash function, refer to
page 240, make sure that after approx.
30 minutes, the parking lock P is automatically
engaged and thus immobilizes the rear wheels.
In the event of an electrical malfunction or if the
vehicle must be towed for more than approx.
20 minutes, unlock the parking lock manually,
refer to page 69.<
When towing, do not exceed a maximum
speed of 30 mph or 50 km/h and a maxi-
mum distance traveled of 30 miles/50 km; oth-
erwise, the transmission may be damaged. <
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise,
damage 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 sh ould 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 ge nerate lateral forces if it is
attached offset.

MobilityGiving and receiving assistance
Attach the tow bar to the tow fittings only,
as attaching it to othe r parts of the vehicle
could result in damage.<
With a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage. <
With a tow truck
Manual transmission and automatic
transmission:
Sport automatic transmission with double
clutch:
Have the BMW transported with a tow truck
with a so-called lift bar, or on a flatbed.
Do not tow the vehicle wi th just the rear axle
raised as this may cause the steering to turn.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump start the engine, refer to
page 251. Vehicles with a catalytic converter
should only be tow-started when the engine is
cold, vehicles with an automatic transmission or
Sport automatic transmission with double
clutch cannot be tow-started at all.
1. Switch on the hazard warning flashers,
comply with local regulations.
2. Switch on the ignition, refer to page 61.
3. Shift into 3rd gear.
4. Have the vehicle tow-started with the clutch
completely depresse d and then slowly
release the clutch. Afte r the engine starts,
immediately depress the clutch completely
again.
5. Stop at a suitable location, remove the
tow bar or rope and switch off the hazard
warning flashers.
6. Have the vehicle checked.
