Starting engine
Do not run the engine in closed rooms;
otherwise, the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
engage the handbrake and move the selector-
lever into position P or shift into neutral before
leaving the vehicle with the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.
Manual transmission
1.Apply the handbrake.
2.Depress the clutch pedal and select the
idling position.
3.Briefly press Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
Automatic transmission with
Steptronic*
1.Depress brake pedal.
2.Briefly press Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-ically disengaging it as soon as the engine
starts.
SMG Sequential Manual Gearbox*
1.Depress brake pedal.
2.Move the selector lever into position N and
make sure that this position is also indi-
cated in the instrument cluster.
3.Briefly press Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
If the engine fails to start, depress the
brake pedal and press the selector lever
to the right and then back into position N.
Watch the display in the instrument cluster
while doing so.<
Special starting conditions
Depress the accelerator pedal halfway when
starting the engine in the following situations:
>The engine fails to start on the first attempt,
e.g. if it is very hot or cold.
>The engine is started at very low tempera-
tures below approx. + 57/– 156 and at
high altitudes over approx. 3,300 ft/
1,000 m.
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned at all or is burned inadequately and
there is a danger of overheating and damage to
the catalytic converter.<
Switching engine off
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 slope, apply the
handbrake; otherwise, the vehicle could roll.<

Driving
62 It is also possible to start off in second gear, e. g.
in slippery conditions.
In the following situations, SMG does the think-
ing 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, the system will not execute a
downshift that would cause the engine to
overrev.
>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.
To switch from Sequential to Drive mode:
Briefly press the selector-lever to the right
toward D.
Kick-down: for rapid acceleration, e.g. passing,
press the accelerator pedal as far down as it will
go. You achieve maximum acceleration.
To switch back to the Sequential mode: press
selector-lever to the right again toward D or
shift using the shifting paddles or the selector-
lever.
Start off quickly on slopes. Do not hold
the vehicle on a hill by applying the throt-
tle, but engage the handbrake instead. Other-
wise, overheating can occur in the region of the
transmission.<
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 shift up, pull one of the shift paddles.
>To shift down, press.
Automatic transmission with
Steptronic*
In addition to the fully automatic mode, you can
also shift manually with Steptronic, refer to
page63.

Changing selector-lever positions
>Only move the selector-lever from
position P with the engine running: inter-
lock.
>With the vehicle stopped, press the brake
before shifting out of P or N; otherwise, the
selector lever is blocked: shiftlock.

Mobile communications devices in
vehicle
BMW advises against using mobile com-
munications devices, e.g. mobile phones,
inside the vehicle without a direct connection
to an external antenna. Otherwise, the vehicle
electronics and mobile communications device
can interfere with one another. In addition, there
is no assurance that the radiation emitted dur-
ing transmission will be conveyed out of 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, also refer to Mini-
mum tire tread on page187.
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
vehicle's engine, electrical systems and trans-
mission 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 Gearbox
Start off quickly on slopes. Do not hold
the vehicle on a hill by applying the throt-
tle, but engage 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 parking brake is
not required for this purpose.
1.Hold the vehicle with the footbrake.
2.Release the footbrake and immediately
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, immediately start
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 at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver 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 driving on wet roads or in heavy rain, it is
a good idea to apply light pressure to the brake
pedal every few miles. Monitor traffic conditions
to ensure that this maneuver does not endan-
ger 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 thus reduced
efficiency of the brake system, downshift
to a gear in which only minimal brake applica-
tions are needed when descending long or
