Driving stability control
systems
Your BMW is equipped with a series of systems
that help maintain driving stability even in
adverse driving situations.
Antilock Brake System ABS
ABS keeps the wheels from locking during
braking. Steering stability is maintained even
during full brake applications. In this way, active
safety is enhanced.
ABS is operational each time the engine is
started. Braking safely, refer to page69.
Electronic brake-force distribution
The system controls brake-force application at
the rear wheels in order to obtain increased sta-
bility in the vehicle's braking response.
Dynamic Brake Control DBC
When the brake pedal is depressed quickly, this
system automatically supplies maximum brake-
servo boost, thereby helping to keep the vehi-
cle's braking distance as short as possible dur-
ing full brake applications. At the same time, the
benefits of the ABS are also exploited.
As long as you are braking, do not reduce pres-
sure on the brake pedal. When the brake pedal
is released, the DBC is switched off.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.The laws of physics cannot be repealed
even with DSC. It will always be the
driver's responsibility to drive in a manner that
matches road conditions. Therefore, do not
limit the additional safety margin by practicing
risky driving.<
Dynamic Traction Control DTC
DTC is a variant of the DSC in which forward
momentum is optimized for special road condi-
tions, e.g. snow-covered roads that have not
yet been cleared. The system ensures maxi-
mum forward momentum, but driving stability is
limited. Therefore, drive carefully in accordance
with conditions.
In the following exceptional circumstances, it
may be effective to activate the DTC for a short
period:
>When driving on snow-covered grades, in
slush or on uncleared, snow-covered roads
>When rocking the vehicle or starting off in
deep snow or on loose surfaces
>When driving with snow chains.
Activating DTC
Press the button briefly; the DTC indicator lamp
lights up in the instrument cluster.
Reactivating DTC
Press the button again; the DTC indicator lamp
goes out in the instrument cluster.

Deactivating DTC and DSC at the same
time
Press and hold the button for at least
3 seconds; the DSC indicator lamp lights up in
the instrument cluster. No more interventions
to increase stability and forward momentum are
carried out.
To enhance vehicle stability, reactivate DSC as
soon as possible.
Reactivating DSC
Press the button briefly; the indicator lamp goes
out in the instrument cluster.
Checking
The indicator lamp flashes:
DSC or DTC is regulating drive torque
and braking forces.
The indicator lamp lights up:
DTC and DSC have been deactivated together
by pressing the DTC button.
The indicator lamp lights up:
DTC has been activated by pressing

Flat Tire Monitor
The concept
As 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 significantly below the pressure of
another tire.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affecting the
rotational speed of the wheels. This change is
detected, and a flat tire warning is issued to the
driver.
System requirements
To ensure a reliable flat tire warning, the system
must be initialized with the correct tire inflation
pressures.
Each time you correct the pressure in a
tire, or change a wheel or tire, the system
must be re-initialized.<
System limitations
The Flat Tire Monitor cannot provide 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 func-
tion in a delayed manner in the following situa-
tions:
>System was not initialized
>You are driving on a snow-covered or slip-
pery road surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>You are driving with snow chains.
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is automatically continued
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine, but do not drive off
2.Press the button as long as you need to until
the yellow indicator lamp in the instrument
cluster lights up for a few seconds
3.Drive off.
Initialization is completed during the drive,
without any feedback issued.

Break-in procedures
Moving parts need to be given some time until
they can interact smoothly with one another. To
ensure that your vehicle provides maximum
economy throughout a long service life, we
request that you observe the following:
Engine and differential
Up to 1,200 miles/2,000 km:
Drive at varying engine and road speeds, but do
not exceed the following engine or road speed:
4,500 rpm / 4,500/min or 100 mph / 160 km/h.
Obey your local and state maximum speed lim-
its.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kickdown point.
After you have driven 1,200 miles/2,000 km,
you can gradually increase the engine or road
speeds.
Sequential manual gearbox SMG
Up to 1,200 miles/2,000 km:
Do not use the acceleration assistant during the
break-in period.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until an initial break-in period has
elapsed. You should therefore drive with extra
caution during the first 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Approx. 300 miles/500 km must elapse before
the brake pads and rotors achieve their optimal
surface and wear pattern.
To break in the separate parking brake drums,
apply the parking brake lightly when coasting to
a standstill – at a traffic signal, for instance; use
caution to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
The brake lamps do not come on when the
parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the car with
the engine off, e.g. by towing, substantially
higher levels of pedal force will be required to
brake the vehicle.<
Clutch
The clutch will achieve its optimal functionality
after approx. 300 miles/500 km. Shift gears
carefully during the break-in period.
After replacing components
Follow the same break-in procedure again if any
of the components mentioned above have to be
replaced in the future.
Driving notes
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed, otherwise exhaust fumes could pene-
trate into the interior of the vehicle.<
Should it be absolutely necessary to operate
the vehicle with the luggage compartment lid
open and with the convertible top closed:

1.Close all windows
2.Increase the air supply from the air condi-
tioner or automatic climate control to a high
level. Refer to page58 or61.
Hot exhaust system
High temperatures occur with every vehi-
cle equipped with a catalytic converter.
Heat shields are installed adjacent to some sec-
tions of the exhaust system. Never remove
these shields; do not apply undercoating to
their surfaces. When driving, standing at idle
and parking the vehicle, take care to avoid con-
tact between the hot exhaust system and flam-
mable materials, e.g. hay, leaves, grass, etc.
Such contact could lead to a fire, resulting in
serious personal injury and property damage.<
Hydroplaning
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the tires and
the road surface. This phenomenon can lead to
partial or complete loss of traction, vehicle con-
trol and braking effectiveness.<
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed. Otherwise, the vehicle's engine,
the electrical systems and the transmission
may be damaged.<
Use the parking brake on inclines
On inclines, keep the vehicle from rolling
by using the parking brake rather than by
slipping the clutch, which would lead to a high
degree of clutch wear.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. If you are in a situation which requires
full braking, it is best to brake using maximum
brake pressure: panic stop. Since the vehicle
maintains steering responsiveness, you can still
avoid possible obstacles 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.
Wet roads
If the roads are wet or if there is heavy rain, it is
advisable to gently press the brakes for a brief
moment every few miles/kilometers. Watch
traffic conditions to ensure that this maneuver
does not endanger other road users. The
resulting heat dries the brake rotors and brake
pads. Immediate braking force is then available
if necessary.
Inclines
To prevent overheating and, as a result,
diminished braking effectiveness, drive
down long or steep downhill grades in a gear
which requires the least braking. Otherwise,
even light but consistent pedal pressure can
lead to high temperatures, brake wear and pos-
sibly even brake failure.<
The braking power of the engine can be further
enhanced by downshifting the automatic trans-
mission in manual mode, if necessary, into first
gear; refer to pages39 and41. This prevents an
excessive load on the brakes.
Do not coast with the clutch depressed or
with the transmission or selector lever in
Neutral. Do not coast with the engine switched
off. Otherwise, the engine provides no braking
effect while the transmission is in idling posi-
tion, and there is no power-assist for braking or
steering when the engine is off.
Floor mats, floor carpets or other objects must
not be in the area near the brake or accelerator
pedal, as this could impair the movement of the
pedals.<
Corrosion on the brake rotors
Limited vehicle use, extended periods with the
vehicle parked or in storage, and operating con-
ditions in which braking is restricted to gentle,
low-pressure applications will all increase the
tendency for corrosion to form on the rotors and
contamination to accumulate on the brake
pads. This occurs because the minimal pres-

Wheels and tires
82
Run Flat tires fitted
Run Flat tires are labeled on the sidewall with a
circular symbol containing the letters RSC.
Run Flat tires consist of self-supporting tires
and special rims. The tire reinforcement
ensures that driving remains possible to a
restricted degree in the event of pressure drop
or even if the tire is deflated.
Wheel and tire replacement
Have new wheels and tires mounted only
by a BMW center or specialized tire shop
that works according to BMW requirements
with the appropriately trained personnel. Work
that is improperly carried out could result in
consequential damage and pose safety haz-
ards. Make sure that the new wheels are bal-
anced.<
BMW advises against using retreaded
tires, since driving safety may be
impaired. This is due to possible variations in
casing structures and, in some cases, to their
extreme age, factors which can lead to a
decrease in their durability.<
The correct wheels and tires
BMW recommends using only wheels
and tires that have been approved by
BMW for your particular vehicle model, as oth-
erwise body contact and serious accidents can
result despite the use of the same nominal size,
e.g. due to manufacturing tolerances. If non-
approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.
nations for your vehicle.
The correct wheel and tire combination also
affects other systems which would otherwise
be impaired, for example ABS or DSC.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. In the event of a flat tire,
remount the previous wheel and tire combina-
tion as soon as possible.
Recommended tire brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. You can best find out about these at a
specialized shop, particularly your BMW center.
Observe any country-specific regulations, e.g.
on making a corresponding entry in the vehicle
documents.
The factory-approved radial-ply tires are
matched to your vehicle and have been
selected to provide optimum safety and driving
comfort when used properly.
Run Flat tires
When mounting new tires or replacing summer
tires with winter tires, or vice versa, use Run Flat
tires since no spare wheel is available in the
event of a flat. Your BMW center will be glad to
provide you with more information.
For safety reasons, BMW recommends to
have Run Flat tires replaced, not repaired,
if they are damaged.<
Special characteristics of winter tires
BMW recommends the use of winter tires for
operation under winter road conditions. While
all-season tires with M+S designation provide
better winter traction than summer tires, they
generally do not achieve the full performance of
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated. Unpro-
fessional attempts by laymen to service tires

with passed dates. These items can be pur-
chased in any drugstore or pharmacy.
Always observe all legal regulations requiring a
first-aid kit to be carried in the vehicle.<
Jump-starting
When your battery is discharged you can use
two jumper cables to start your vehicle with
power from the battery in a second vehicle. You
can also use the same method to help start
another vehicle. Always use jumper cables with
fully insulated handles on the terminal clamps.
Do not touch components carrying cur-
rent on a running engine. Contact with
these components can cause fatal injury. Care-fully observe the following instructions to avoid
personal injury and/or damage to one or both
vehicles.<
Preparations
1.Check whether the battery of the support
vehicle has 12 volts and approximately the
same capacity – measured in Ah. This infor-
mation is provided on the battery
2.Stop the engine of the support vehicle
3.Switch off all electrical accessories in both
vehicles.
Make absolutely certain that there is no
contact between the bodywork of the two
vehicles: short circuit hazard.<
Connecting jumper cables
Always adhere to this sequence when
connecting jumper cables; failure to
observe this procedure can lead to sparks at the
battery terminals and pose an injury hazard.<
The auxiliary jump-starting terminal located in
your BMW's engine compartment acts as the
positive battery terminal. Refer to the engine
compartment overview on page85. The cover
is marked with a+.
1.Open the cover of the BMW auxiliary jump-
starting terminal. Do so by pulling the tab
2.With the + jumper cable, connect the posi-
tive terminal of the drained battery and the
positive terminal of the support battery.
