Launch Control
Launch Control enables an optimum accelera-
tion when starting off on a road surface with
good traction.
Do not use Launch Control too often; oth-
erwise, the powerful stresses on the vehi-
cle will lead to premature component wear. <
Launch Control is available when the engine is
at operating temperature, i.e. after driving con-
tinuously for approx. 6.2 miles/10 km.
1. With the engine running, step on the brake
with your left foot.
2. Activate Dynamic Traction Control DTC,
refer to page 96.
3. Activate Driving dynamics control, refer to
page 68.
4. With the vehicle stationary, activate the
manual mode and select 1
stgear.
5. With your right foot, push the accelerator
pedal past the resistance point. The engine
speed for pulling away is adjusted. A flag
symbol appears in the instrument cluster.
6. When you release the brake pedal, the vehi-
cle accelerates. Keep the accelerator pedal
floored.
7. The upshifting occurs automatically as long
as you keep the accelerator pedal pressed
past the resistance point.
Launch Control will be ready for use again after
you drive a certain distance.
Launch Control is not available for use during
the break-in phase, refer to page 136.
To maintain driving stability, keep DSC
activated whenever possible. <

when the manual transmission is shifted
very slowly or shifted into neutral.
> when the automatic transmission selector
lever is moved into the neutral position.
> when the selector lever of the sport auto-
matic transmission with double clutch is
moved into the neutral position.
> when Dynamic Traction Control DTC is
activated.
> when Dynamic Stability Control DSC is
deactivated.
> when DSC or ABS is intervening.
> when the system does not recognize any
objects for a longer time, e. g. on infre-
quently traveled roads without a shoulder or
guard rails, or if the radar sensor is covered
with dirt, refer to page 77.
> when the parking brake is engaged.
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary; otherwise, there is a
risk of accidents.<

Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Display.
PDC is malfunctioning. Have the sys-
tem checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate 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 tone 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 limits that apply to all forms
of ultrasonic measurement, such as those
encountered with trailer 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 exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure 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 limits 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 the responsibility of the
driver. Therefore, do not reduce the additional

safety margin again by taking risks, as this could
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 Control DTC and DSC have
been simultaneously deactivated. Stabilizing
and drive-output promoting actions are no
longer executed.
In the same way as with a differential interlock,
even if DSC is deactivated, brake actions are
still performed to enhance drive output if the
drive wheels experience a significant loss of
traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out.
For better control
If the indicator lamp flashes: the DSC
controls the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and
DSC OFF is displayed in the instrument
cluster: DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving uphill on snow-covered roads,
in slush or on unplowed, snow-covered
roads
> When rocking a stuck vehicle free or start-
ing off in deep snow or on loose ground
> When driving with snow chains
Activating DTC
Press the button; the indicator lamp for DSC
OFF lights up and TRACTION is displayed in
the instrument cluster.
For better control
If the indicator lamp flashes: DTC con-
trols the driving and braking forces.
If the indicator lamp lights up: DSC and
DTC have failed.
The indicator lamp lights up and TRAC-
TION is displayed in the instrument
cluster: DTC is activated.
Deactivating DTC
Press the button again; the indicator lamp in the
instrument cluster goes out.

xDrive
xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the driving situation and road
conditions.
Hill Descent Control HDC
HDC is a downhill driving assistant that controls
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly faster than double walking
speed without the driver needing to intervene.
HDC is available for activation at vehicle speeds
below approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 miles or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or decreasing speed
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range of between approx. 3 mph/5 km/h and
20 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.

the LED flashes.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated at speeds
over approx. 40 mph or 60 km/h.
Using HDC

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 100 mph (160 km/h)
T = up to 118 mph or 190 km/h
H = up to 131 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 190 mph (300 km/h)
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT … 1012 means that the
tire was manufactured in week 10 of 2012.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades. <
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics. <
