Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter.<
Switching off engine
Do not remove the remote control from
the ignition lock while the vehicle is roll-
ing, otherwise the steering-wheel lock would
engage while steering.
When leaving the vehicle, always take the
remote control with you.
When parking on a downhill incline, apply the
handbrake, otherwise the vehicle could roll
away.<
Manual transmission
1.Briefly press the Start/Stop button with the
vehicle stopped.
2.Shift into first gear or reverse.
3.Apply the handbrake.
SMG Sequential Manual
Transmission*
1.Apply the handbrake.
2.Engage a driving position.
3.Briefly press the Start/Stop button.
If N is engaged when switching off the
engine, this will be pointed out to you opti-
cally and acoustically.
Automatic transmission*
1.Select selector lever position P with the
vehicle stopped.
2.Briefly press the Start/Stop button.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Engaging
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise
excessive pressure can lead to the rear wheels
locking up and loss of traction – fishtailing – at
the rear axle.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<

Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
Sequential mode
After every engine start, as soon as the selector
lever is pushed to the right and the brake pedal
is depressed, the Sequential mode is activated.
You can shift up and down using the shift pad-
dles or the selector lever. You do not need to
remove your foot from the accelerator to do so.
It is also possible to start off in second gear, e. g.
in slippery conditions.
In the following situations, SMG thinks for you:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
>When the vehicle is stationary, the trans-
mission automatically downshifts into first
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.
D Drive mode
In the Drive mode, all forward gears are shifted
automatically.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D.
Kick-down: for rapid acceleration, e. g. when
passing, press the accelerator pedal as far
down as it will go. You achieve maximum accel-
eration.
To switch back into the Sequential mode: press
selector lever to the right again toward D or shift
using the shift paddles or the selector lever.Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Gear changes
Using selector lever
>To upshift, pull the selector lever back.
>To downshift, push the selector lever for-
ward.
Using shift paddles on steering wheel
>To upshift, pull one of the shift paddles.
>To downshift, press.
Dynamic Driving Control
The Dynamic Driving Control makes it possible
for your BMW to react in an even more perfor-
mance-oriented manner at the push of a button:
>The engine responds more spontaneously
to accelerator pedal movements.
>Gearshifts are faster.
>The engine speed range is used optimally in
the Drive mode.
>Cruise control
*:
The stored speed is reached more quickly
when it is requested.

Mobile communications devices in
vehicle
BMW discourages the use of mobile
communications devices, e. g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page213.
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 at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential Manual Transmission
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The handbrake is not
required for this purpose.
1.Hold the vehicle with the footbrake.
2.Release the footbrake and drive off quickly.
The starting assistant holds the vehicle
for approx. 2 seconds after releasing the
footbrake. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the footbrake, drive off quickly,
otherwise the starting assistant no longer holds
the vehicle after approx. 2 seconds and it
begins to roll back.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pressure on the brake pedal
