Technology for driving comfort and safety
Controls
Malfunction
The warning lamp lights up. A mes-
sage appears on th
e Control Display.
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.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal to ne sounds. The display
appears on the Control Display as soon as PDC
is activated.
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. 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 page138.
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.

Vehicle equipment
In this chapter, all pr oduction, 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
Coupe
The onboard vehicle tool kit is stored in a com-
partment on the right-ha nd side of the trunk.
Remove the cover.
Convertible
The onboard vehicle tool kit is stored in a pouch
under the trunk floor panel.
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 ou t 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 something 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. <

MobilityGiving and receiving assistance
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. <
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 263, note that the parking lock P is
engaged automatically after approx.
30 minutes, blocking 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 70.<
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 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 la teral forces if it is
attached offset.
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: vehicle without xDrive
Manual 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 with just the rear axle
raised as this may cause the steering to turn.

Giving and receiving assistance
Mobility
With a tow truck: vehicle with xDrive
Do not tow a BMW with xDrive with just
the front or rear axle raised; otherwise, the
wheels could lock up and the transfer case
could be damaged. <
Have the BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump start the engine, refer to
page 274. Vehicles with a catalytic converter
should only be tow-star ted 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 hazard warning flashers, comply
with local regulations.
2. Switch on the ignition, refer to page 62.
3. Shift into 3rd gear.
4. Have the vehicle tow-st arted with the clutch
depressed and slowly release the clutch.
After 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.
With xDrive: do not activate Hill Descent
Control HDC when the vehicle is being
tow-started, page 99.<
