Starting the engine
Do not run the engine in closed rooms,
otherwise the inhaling 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, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the hand-
brake to prevent the car from moving.<
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.
Do not depress either the brake or the
clutch until you are ready to start the
engine. The engine is started immediately
when you briefly touch the start/stop button
and depress the brake if the car has automatic
transmission, or the clutch if the car has manual
transmission.<
Manual transmission
1.Apply the handbrake.
2.Depress the clutch and shift to idle position.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission
1.Depress the brake.
2.Move the selector lever to position P.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Sequential manual gearbox SMG*
1.Depress the brake.
2.Engage selector lever position N and make
sure that this position is displayed in the
instrument cluster.
3.Start the engine.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
If the engine does not start, depress the
brake and push the selector lever to the
right, then engage position N. Observe the dis-
play in the instrument cluster while doing so.<
Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. + 57/–156, at high
altitudes above 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 or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking on a downhill incline, apply the

Sequential mode
After every engine start, sequential mode is
activated when you press the selector lever
towards the right while the brake is depressed.
You can shift up or down using the shift paddles
or the selector lever. You do not need to lift your
foot from the accelerator pedal while doing so.
It is also possible to start off in second gear, e.g.
on slippery surfaces.
SMG assists you in the following situations:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; for exam-
ple, a downshift that would cause the
engine to overrev cannot be executed by
the system.
>The system shifts down into first gear auto-
matically when the vehicle comes to a stop.
>The system shifts down automatically just
before the engine speed falls below the
minimum speed required for a certain gear;
the driver does not need to intervene.
Shifting gears via selector lever
>Pull the selector lever backwards to shift up.
>Push it forward to shift down.
Shifting gears via the shift paddles on
the steering wheel
>Pull one of the shift paddles to shift up.
>Press it to shift down.
D Drive mode
In Drive mode, all forward gears are shifted
automatically.To switch from sequential mode to Drive mode:
press the selector lever towards the right in the
direction of D.
Kick-down: to accelerate rapidly, e.g. when
passing another vehicle, depress the accelera-
tor pedal all the way. You will achieve maximum
acceleration.
To switch back to sequential mode: press the
selector lever again towards the right in the
direction of D or shift gears via the shift paddles
or the selector lever.
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; engage the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Dynamic Driving Control
Dynamic Driving Control enables you to drive
your BMW in an even more performance-ori-
ented manner at the touch of a button:
>Gears are shifted more quickly.
>In Drive mode, the engine speed range is
utilized optimally.
Activating the system
Press the SPORT button while the ignition is
switched on. The LED in the button lights up.
Deactivating the system
>Press the SPORT button again or
>engage reverse gear or
>switch off the engine.
The LED in the button goes out.

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.<
Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
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 situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page195.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Sequential manual gearbox SMG
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; apply the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Also use the drive-off assistant, refer to
page87.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. 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.
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 brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
