Ignition lock
0 Steering locked
This is the only position in which the ignition key
can be inserted or removed.
After removing the key, turn the steering wheel
slightly to the left or right until the lock engages.
If the key is not removed, an acoustic signal
sounds when the driver's door is opened.
Interlock
Vehicles with automatic transmission:
In order to turn the key back to position0 or to
remove it, move the selector level into position
P first.
1 Steering unlocked
You will find that it is often easier to turn the
ignition key from position0 to 1 if you move the
steering wheel slightly to help disengage the
detent.
Individual electrical equipment and accessories
are available for use.
2 Ignition switched on
All systems are operational.
3 Starting engine
Engine
Engine idle speed is controlled by the engine
computer system. Increased speeds at start-up are normal and should decrease as the engine
warms up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging, always
deactivate electrical devices that are not in use.
Switch the ignition off when the vehicle is not
being driven.
Do not leave the engine running in
enclosed spaces. Otherwise, inhaling the
hazardous exhaust gases could lead to uncon-
sciousness and death. The exhaust gases con-
tain carbon monoxide, an odorless and color-
less, but highly toxic gas.
Do not leave the vehicle unattended with the
engine running. An unattended vehicle with a
running engine poses a safety hazard.
Before you leave the vehicle with the engine
running, place the engine in idle first or engage
the P position and apply the parking brake. If
you fail to do this, the vehicle could move.<
Starting the engine
Do not press the accelerator pedal while start-
ing the engine.
Do not let the engine warm up in idling position.
Instead, begin to drive at moderate engine
speeds.
Vehicles with manual transmission:
Step on the clutch when starting the vehi-
cle. A lockout prevents the engine from starting
if the clutch is not depressed.<
Do not end the starting procedure too early, but
do not continue it for more than 20 seconds.
Release the ignition key immediately when the
engine starts.
If the engine fails to start on the first attempt,
e.g. if it is very hot or cold:
Press the accelerator pedal halfway down.
Cold starts at very low temperatures, below
approx. +57/–156, and at high altitudes,
above 3,300 ft/1,000 m:

tion N again.<
Switching off the engine
Do not remove the ignition key while the
vehicle is still moving. If you did so, the
steering lock would engage when the steering
wheel is turned.
When you leave the vehicle, always remove the
ignition key and engage the steering lock.
Apply the parking brake when parking on steep
gradients, as the vehicle could otherwise start
to roll.<
You can have an acoustic signal set as a
reminder that the ignition key is still in the ignition switch after the driver's door has been
opened.<

Parking brake
The parking brake is designed primarily to pre-
vent the vehicle from rolling when parked. It
operates against the rear wheels.
The indicator lamp lights up. As the
vehicle drives off, an acoustic signal
also sounds. The parking brake has
been applied.

To release
Pull up slightly on the lever, press the button
and lower the lever.
If, in exceptional circumstances, it should
be necessary to engage the parking brake
while the vehicle is in motion, do not pull it with
excessive pressure. Keep the release button on
the parking brake lever pressed down while
pulling up the lever.
Excessive pressure can lead to overbraking and
loss of traction, fishtailing, at the rear axle.
The brake lamps do not come on when the
parking brake is engaged.<
To avoid corrosion and one-sided brak-
ing, apply the parking brake lightly from
time to time when coasting to a standstill at a
traffic signal, for example, provided that it is safe
to do so.<
Manual transmission
6-gear transmission*
When shifting into 5th or 6th gear, press
the gearshift lever to the right. Otherwise,
the engine could be damaged by accidentally
engaging 3rd or 4th gear.<
Reverse

Kickdown:
For rapid acceleration, e.g. during passing,
depress the accelerator pedal completely. You
achieve maximum acceleration.
To switch back to sequential mode: tap the
selector lever again to the right toward D, or
change the current gear via the shift paddles or
the selector lever.
When driving off on inclines, drive
smoothly without pausing. Do not keep
the vehicle in place by depressing the accelera-
tor pedal; instead, apply the parking brake. Oth-
erwise, the gearbox could overheat.<
Shifting gears
With selector lever
>To upshift, tap the selector lever toward +
>To downshift, tap the lever toward –.
With shift paddles on steering wheel
>To upshift, pull one of the shift paddles
>To downshift, push the paddle.
In the following situations, the SMG in the
sequential mode assists you:
>The transmission will only execute upshifts
and downshifts that will result in an appro-
priate combination of vehicle speed and
engine rpm. For instance, downshifts that
would result in excessive engine speed
cannot be executed
>During a stop the gearbox is automatically
downshifted into first gear
>Shortly before a gear-dependent minimum
speed is reached, the gearbox automatically
shifts down without you taking any action.
Malfunction
The warning lamp lights up. The trans-
mission system is malfunctioning.
Avoid heavy loads.
All of the selector lever positions can continue
to be engaged; in the forward drive positions,
however, the vehicle will be operating in a
restricted gear range only. Have the system
checked as soon as possible.
Towing and tow-starting, refer to page98;
Jump starting, refer to page97.
Overheating
An acoustic warning signal sounds. The gear-
box is overheating. If possible, stop the vehicle
or drive off swiftly so that the system can cool
off again.
Driving Dynamic Control
Driving Dynamic Control allows your BMW to
react in a sportier driving style at the touch of a
button:
>The engine responds more spontaneously
to any motion of the accelerator pedal
>The vehicle is steered more directly and
traction is enhanced
>Cruise control:
When the speed last stored is called up, this
speed is attained more quickly.
Additional features with SMG:
>Gears are shifted more quickly
>The engine speed range is optimally utilized
in the drive mode.
With automatic transmission:
>The Sport program is activated.

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-
