Starting the 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, otherwis e such a vehicle repre-
sents a potential safety hazard.
Before leaving the car wi th the engine running,
place the transmission in neutral or move the
selector lever to position P and set the parking
brake to prevent the car from moving. <
Avoid frequent starting in quick succes-
sion as well as repeat ed start attempts in
which the engine does no t start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter. <
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to
page 35.
1. Depress the brake.
2. Depress the clutch and shift to neutral
position.
3. 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
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to
page 35.
1. Depress the brake.
2. Move the selector lever to position P.
3. Press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
7-gear sport automatic transmission
with dual clutch
Remote control in the ignition lock or, with con-
venient access, inside the vehicle, refer to
page 35.
1. Depress the brake.
2. Press the start/stop button.
The engine starts, regardless of the current
selector lever position.

Driving
56
The indicator lamp lights up yellow if
the transmission becomes too warm.
Avoid high engine loads and driving off
frequently. If the transmission overheats, the
indicator lamp lights up red and power flow to
the engine is interrupted. You can only continue
driving after the transmi ssion has cooled down.
Avoid driving off frequently with a high acceler-
ation and do not hold the vehicle on inclines by
depressing the accelerato r lightly and dragging
the clutch; otherwise, the transmission may
overheat.
Transmission positions
P R N D M/S + –
Displays in the instrument cluster
P, R, N, D1 to D7, S1 to S7, M1 to M7
The transmission position and the gear cur-
rently engaged are displayed.
Engaging a transmission position
> Transmission position P can only be disen-
gaged if the engine is running.
> Before moving the lever away from P or N
with the vehicle stat ionary, depress the
brake; otherwise, the transmission will not
shift.
Engaging N, D, R
Briefly push the selector lever in the desired
direction, beyond a resi stance point if neces-
sary. When shifting out of P or into R, press
button 1 at the same time.
The engaged transmission position is also dis-
played on the selector lever.
When you release the sele ctor lever, it returns
to its center position.
Engaging P
Press button P.
P Park
Select this only when th e vehicle is stationary.
The rear wheels are locked.
P engages when you open the driver's
door while the engine is running, your
safety belt is not fastened and you activate nei-
ther the brake pedal nor the accelerator.<
P is engaged automatically when you
switch off the engine, unless N is
engaged and the remote co ntrol is in the igni-
tion lock, refer to page 50. As soon as you
remove the remote cont rol from the ignition
lock, P engages regardless of the position of the
selector lever. <

Things to remember when driving
112
The risk of hydroplaning
increases with declin-
ing tread depth on the tire s, refer also to Mini-
mum tread depth on page 194.
Driving through water
Drive though calm water only if it is not
deeper than 1 ft/25 cm and at this height
no faster than walking speed, up to 6 mph/
10 km/h. Otherwise, the vehicle's engine, the
electrical systems and the transmission may be
damaged. <
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Ot herwise greater clutch
wear will result. <
For more information about the drive-off assis-
tant, refer to page 80.
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 pre ssure 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. Full
braking efficiency will th en 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 br aking is required. Even light but consistent brak
e pressure can lead to
high temperatures, brake wear and possibly
even brake failure. <
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page 54.
7-gear sport automatic transmission with
dual clutch: Never drive with the trans-
mission in neutral or with the engine switched
off; otherwise, engine braking action will not be
present or there will be no power assistance to
the brakes or steering.
Manual transmission: Never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
engine braking action will not be present or
there will be no power a ssistance to the brakes
or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise peda l function could be
impaired. <
Corrosion on brake rotors
When the vehicle is driv en only occasionally,
during extended periods when the vehicle is not
used at all, and in op erating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to re spond with a pulsating
effect that even extended application will fail
to cure.
When the vehicle is parked
Condensation forms wh ile the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
