Driving
56 do not pull it too strongly. In doing so, con-
tinuously press the button of the handbrake
lever.
Strong application of the handbrake can
lead to overbraking of the rear axle and
associated 'fishtailing' of the vehicle rear
end.
The brake lamps do not light up when the
handbrake is engaged.
Vehicles with manual or SMG transmission:
When parking on inclines, engage the
handbrake, as even engaging the first or
reverse gear might not under certain cir-
cumstances secure the vehicle against
moving.
Vehicles with automatic transmission:
Engage selector-lever position P.<
To prevent corrosion and one-sided
braking action, occasionally engage
the handbrake lightly when the vehicle is
slowly coming to a standstill if the traffic
conditions are suitable.<
Manual transmission
While shifting gear in the 5th/6th gear
level, press the gearshift lever to the
right, as otherwise engine damage could
occur from inadvertently engaging a gear in
the 3rd/4th gear level.
On inclines, do not hold the vehicle with the
clutch; use the handbrake. Otherwise there
is high clutch wear.<
Reverse gear
Select only when the vehicle is completely
stationary. When pressing the gearshift
lever to the left, overcome some resis-
tance.The backup lamps automatically switch on
in ignition key position 2.
SMG Sequential manual
transmission*
The concept
The SMG Sequential manual transmission
is an automated manual transmission in
which an electro-hydraulic system handles
the clutching and gear changes.
You operate the SMG using the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Options of two drive programs:
Normal or Sport, refer to page 59
>Protection against incorrect gearshifts
and automatic shift down at minimum
engine speed, also in the Sequential
mode
>Kickdown function in the Drive mode
>Acceleration assistant, refer to
page 60.
The SMG is operational in ignition key posi-
tion 2.
Selector-lever positions
The current selector-lever position is dis-
played on the center console.
>R: Reverse gear
>N: Neutral, idle

>D: Drive mode.
N is automatically engaged if the
driver's door is opened with the
engine running and neither pedals, shift
paddles nor the selector lever are oper-
ated.
This is indicated by an acoustic signal and
the flashing display N in the instrument
cluster.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, in
the Drive mode preceded by a D.
Shiftlock
Press the brake pedal before shifting out
of N; the shift command will not be exe-
cuted unless the brake is applied.
R Reverse
Select only when the vehicle is completely
stationary.
Sequential mode
After every engine start, as soon as the
selector lever is pushed to the right and the
brake pedal is pressed, the Sequential
mode is activated.
The gear is changed using the shift paddles
or selector lever.
Driving off is also possible in second gear,
e.g. when the roadway is icy.
D Drive mode
In the Drive mode, all forward gears are
shifted automatically.
To switch from Sequential to Drive mode:
Briefly press the selector lever to the right
towards D.
Kickdown:
For rapid acceleration, e.g. overtaking,
press the accelerator pedal as far down as
it will go: you achieve maximum accelera-
tion.
To switch back to the Sequential mode:
briefly press the selector lever back to the
right towards D or change the current gear
using the shift paddles or selector lever.
Start off quickly on slopes. Do not
hold the vehicle on a hill by applying
the throttle, but engage the handbrake
instead. Otherwise overheating can occur
in the area of the transmission.<
Gear changes
Using selector lever
>To shift up, briefly press the selector
lever towards +
>To shift down, briefly press towards —.
Using shift paddles on steering
wheel
>To shift up, pull one of the shift paddles
>To shift down, press.
In the following situations, the SMG in the
Sequential mode assists you:
>Upshifts and downshifts are executed
only when they will result in a plausible
combination of engine and vehicle

76 indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Control Center, for principle details, refer to
page 16:
1.Press button.
The start menu is opened
2.Press the controller to open the menu
3.Select "Vehicle settings" and press the
controller
4.Select "PDC" and press the controller
5.Select "Monitor display on" and press
the controller.
The PDC screen is activated.
The display appears on the Control Display
as soon as PDC is activated.
Depending on which key you have used to
open the vehicle, the last adjustment is
applied.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always
remains with the driver. Even when sensors
are involved, there is a blind spot in which objects cannot be detected. The system is
also subject to the physical limits that apply
to all forms of ultrasonic measurement,
such as those encountered with thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside your
vehicle may prevent you from hearing the
PDC signal tone.<
Do not apply high pressure spray to
the sensors for a prolonged period of
time. Keep the spray at least 4 in/10 cm
away from the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on ABS and DSC.
ABS Antilock Brake System
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS is operational every time you start the
engine. ABS includes the functions CBC
Cornering Brake Control and EBV Elec-
tronic brake-force distribution.
CBC Cornering Brake Control
It provides further enhancements in vehicle
stability and steering response during lane
changes and cornering at high rates of lat-
eral acceleration.
EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.

Report of a flat tire
The warning lamp lights up in red
and a message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat tire
or extensive inflation pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
side walls of the run-flat tires,
inflation pressure loss can not usually
be recognized from the outside, refer to
Run-flat tires on page 168.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page 168.
Malfunction
The warning lamp lights up yellow
and a message appears on the
Control Display. The Flat Tire Moni-
tor has a malfunction or has failed. Have
the system checked as soon as possible.
Active steering*
The concept
The active steering is a system that actively
varies the steering angle of the front wheels
in relation to the steering wheel move-
ments.
When you are driving in the low road speed
range, e.g. in a town or when parking, the
steering angle of the wheels is reinforced,
i.e. the steering becomes very direct.
In the higher speed range, on the other
hand, the steering angle of the wheels is
reduced more and more. This improves the
handling capability of your BMW over the
entire speed range.
In critical situations, the system can make
targeted changes to the steering angle pro-
vided by the driver and thus stabilize the
vehicle before the driver intervenes.
Malfunction
The fixed warning lamp lights up.
The active steering is no longer
operational. In the low speed range,
greater steering wheel movement is neces-
sary. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply
interruption, the system must be activated
with initialization.
Initializing system
1.Start the engine
2.With the vehicle stationary, turn the
steering wheel from the straight-ahead
position to the left as far as it will go and
then back to the straight-ahead position
3.Switch off the engine.
When you start the engine again, all the
functions of the active steering are avail-
able once again.
Brake Force Display
The two-stage brake lamps light up in two
stages depending on how strongly you
brake.
>Normal braking:
The brake lamps and the third brake
lamp go on
>Heavy braking and braking with ABS:
In addition, the light area of the rear
brake lamps is enlarged, refer to illus-
tration.
