Indicator lamp
The gearbox indicator lamp in
the instrument cluster goes out
after the engine is started.
>If it does not go out, or if it lights up
during driving, a malfunction has
occurred. The available functions
may be limited under certain circum-
stances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the opti-
mum shifting point shortly before the
maximum engine speed is reached.
1. When the maximum engine speed is
approached, yellow indicator fields –
shift lights – in the tachometer light
up consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.
Tire replacement, snow chainsFollowing a tire or wheel change and
after mounting or removing snow
chains, the slip recognition of the
SMG Drivelogic must become familiar
with the changed condition.
Reinitialize the system afterwards.
1. Move the selector lever into
position N on a straight stretch of
road at a speed of over 20 mph /
30 km/h
2. Pull both shift paddles for approx.
2 seconds.
If you do not carry out the initialization,
the system automatically learns the
changed condition gradually during
driving. This can become apparent due
to brief opening and closing of the
clutch.

1Clean windshield and headlampsClean windshield and headlamps*The system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
When the vehicle's lighting system is
switched on, the headlamps will also be
cleaned at reasonable intervals.
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. Always use a wind-
shield washer antifreeze in cold
weather. Refer to page 122.
Do not use the washers if the fluid res-
ervoir is empty, as the washer pump
will otherwise be damaged.<
Windshield washer nozzlesThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.
Cruise control*Starting at about 20 mph / 30 km/h, you
can maintain and store any vehicle
speed that you specify.
The cruise control is operational when-
ever the engine is running and the sys-
tem has been activated.To activate the systemIn ignition key position 2:
Press the button in the steering wheel.
The indicator lamp in the instrument
cluster comes on, refer to page 21. You
can now use the cruise control.
Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, or when the road surface is slick
– snow, rain, ice – or loose – rocks or
gravel, sand. until the indicator lamp in the instru-
ment cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.

Dynamic Stability Control (DSC)The conceptDSC supports vehicle stability, even in
critical driving situations.
DSC optimizes driving stability and
traction during acceleration and when
you are starting from a standstill. In
addition, it also recognizes unstable
vehicle conditions, such as understeer-
ing and oversteering. By reducing
engine power and applying brakes at
the wheels, DSC helps to keep the
vehicle on a steady course within phys-
ically feasible limits.
DSC starts up automatically each time
you start the engine.
The laws of physics cannot be
repealed, even with DSC. The
driver remains responsible for the con-
sequences of any inadequate driving
style. Therefore, do not take any risks
because of the additional safety pro-
vided. Do not make any modifications
to the DSC system. Allow only autho-
rized technicians to perform service
procedures on the DSC.<
Indicator lamp for DSC
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 20.
>The indicator lamp flashes: DSC is
active and is controlling the drive
torque based on driving conditions
>The indicator lamp does not go out
after the engine is started or lights up
continuously while you are driving:
DSC has been deactivated via the
button or is defective.
You can continue to drive the vehicle
normally without DSC. In the event of a
malfunction, contact a BMW center or a
workshop that works according to
BMW requirements with appropriately
trained personnel.
M Track mode*M track mode is a feature of the
Dynamic Stability Control DSC,
designed for driving on dry roads. It
allows you to drive with higher longitu-
dinal and lateral acceleration, whereas
driving stability is somewhat reduced.
Only in its absolute limit range will the
system try to stabilize the vehicle by
reducing engine power and applying
brakes to the wheels. Under these driv-
ing conditions the driver must be pre-
pared to perform corrective steering
movements if necessary.
By default, M Track mode is off after
each engine start.
While M Track mode is active, sta-
bilising interventions are per-
formed to a reduced extent only.<
To maintain vehicle stability,
always drive with DSC switched
on and M Track mode switched off
whenever possible. The indicator lamp goes out
shortly after the ignition is
switched on.
>Indicator lamp stays on: M Track
mode ist on
>Indicator lamp stays on and DSC
indicator lamp flashes:
M Track mode is actively regulating
drive torque and braking forces.

Activating M Track modeTap the button; the indicator lamp
comes on and stays on.Deactivating M Track modePress the button again; the indicator
lamp goes out.
To deactivate DSCPress the DSC button; the DSC indica-
tor lamp lights up continuously. DSC
and M Track mode are off.
When better traction is required, it is
beneficial to deactivate the system in
the following situations:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
To maintain vehicle stability,
always drive with the system
switched on whenever possible. tor lamp goes out.
Flat Tire MonitorThe conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
In the event of tire pressure loss, the
rolling radius of the tire changes, and
thereby the rotational speed of the
wheel. This change is detected, and a
flat tire warning is issued to the driver.Functional requirementsTo ensure a reliable flat tire warning,
the system must be initialized with the
correct tire inflation pressures.
Initialize the system immediately
after you have corrected a tire
inflation pressure, or changed the tire
or wheel. The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<

The system could issue a false warning
or function in a delayed manner in the
following situations:
>System was not initialized
>You are driving on a snow-covered or
slippery road surface
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>You are driving with snow chainsInitializing the system
The initialization is completed
while you are driving, and can be
interrupted at any time. Initialization is
automatically continued when you con-
tinue driving. When driving with snow
chains, do not initialize the system.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to, but no more than 8 seconds, until
the indicator lamp in the instrument
cluster lights up in yellow for several
seconds
3. Drive off. Initialization is completed
during the drive without any feed-
back issued.
When driving with snow chains,
do not initialize the system.<
To activate/deactivate the systemThe system is automatically activated in
ignition key position 2 and conse-
quently is on whenever the vehicle is
operated.
To deactivate the system: tap the but-
ton, the indicator lamp will light up yel-
low.
To activate the system: tap the button
again; the indicator lamp goes out.
Deactivate the system when snow
chains are mounted, since false warn-
ings and undetected losses in pressure
are possible under these kinds of con-
ditions.

The indicator lamp in the instru-
ment cluster lights up red. In
addition, an acoustic signal is
sounded.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Fix the flat tire using the M Mobility
system, refer to page 137
4. Press the button for approx.
4 seconds. The red indicator lamp
goes out.
After replacing the damaged tire, initial-
ize the system.

ment cluster lights up yellow.
The Flat Tire Monitor is malfunc-
tioning or out of order. Please contact
your BMW center for additional infor-
mation.
M Engine dynamics controlThe system – Sport mode – will cause
the engine to respond more spontane-
ously to any motion of the accelerator
pedal.Activating/deactivating Sport
modeActivating: with the ignition key in posi-
tion 2, press the SPORT button. The
indicator lamp will come on.
Each time you activate the sys-
tem, the vehicle may gain speed

Antilock Brake System (ABS)The conceptABS keeps the wheels from locking
during braking, thereby enhancing
active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum pedal pressure: panic stop. Since
the vehicle maintains steering respon-
siveness, you can avoid possible obsta-
cles with a minimum of steering effort.
Pulsation at the brake pedal combines
with sounds from the hydraulic circuits
to indicate to the driver that ABS is in
its active mode.Dynamic Brake Control (DBC)DBC is included in the DSC, refer to
page 82.
If you apply the brakes rapidly, this sys-
tem automatically generates maximum
braking force boost and thus helps to
achieve the shortest possible braking
distance in panic braking situations. All
of the benefits of the ABS are exploited
under these circumstances.Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
Cornering Brake Control (CBC)CBC is an advanced engineering
design of the ABS. When braking while
cornering at high speed or braking dur-
ing high lateral acceleration, or when
braking during a lane change, vehicle
stability is improved and steering
response is enhanced.

112Wheels and tires
Tire inflation pressureInformation for your safetyIt is not merely the tire's service life, but
also driving comfort and, above all else,
driving safety that depend on the condi-
tion of the tires and the maintenance of
the specified tire pressure.Checking tire pressuresOnly check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
Check tire inflation pressures reg-
ularly and correct them if neces-
sary: at least twice a month and before
beginning a longer trip. Otherwise,
incorrect tire pressures can cause driv-
ing instability or tire damage, ultimately
resulting in accidents. Do not drive on a
deflated, i.e. flat, tire. A flat tire greatly
impairs steering and braking response,
and can lead to complete loss of con-
trol over the vehicle.<
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor,
refer to page 84.
Inflation pressures for original
tiresTire pressures for the standard tires of
your vehicle are shown on the driver's
door post, visible when the door is
open.
The inflation pressures apply to BMW-
approved tire sizes and recommended
tire brands. Your BMW center will be
glad to supply this information.Inflation pressures for other tire
sizesThe following tire pressure table shows
all tire pressures for the given tire sizes
at ambient temperature.
