Radio readiness and ignition off
All indicator and warning lamps in the instru-
ment cluster go out.
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.
Before leaving the vehicle with the engine run-
ning, select the idling position, or shift the trans-
mission into position P and firmly apply the
handbrake, otherwise the vehicle can begin to
roll.<
Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned at all or is burned inade-
quately and there is a danger of overheating and
damage to the catalytic converter.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, drive off at a moderate engine speed.
Manual transmission
Remote control in ignition lock or with comfort
access in vehicle, refer to page36.
1.Depress brake pedal.
2.Depress the clutch pedal and select the
idling position.
3.Press the Start/Stop button.
Sport automatic transmission*
Remote control in ignition lock or with comfort
access in vehicle, refer to page36.
1.Depress brake pedal.
2.Press the Start/Stop button.
Switching engine off
When leaving the vehicle, always take the
remote control with you.
When parking, firmly apply the handbrake, as
otherwise the vehicle could roll.<
Manual transmission
1.Press the Start/Stop button with the vehicle
stopped.
2.Shift into first gear or reverse.
3.Firmly apply the handbrake.
4.Remove the remote control from the igni-
tion lock, refer to page58.
Sport automatic transmission*
1.Shift transmission into position P with the
vehicle stopped.
2.Press the Start/Stop button.
3.Firmly apply the handbrake.
4.Remove the remote control from the igni-
tion lock, refer to page58.
Before driving into a car wash
The vehicle can roll if you proceed according to
the following steps:
1.With comfort access: insert the remote con-
trol into the ignition lock.
2.Depress brake pedal.
3.Shift into transmission position N.
4.switch off the engine.
Transmission position P will be engaged:
>automatically after approx. 30 minutes
>if you remove the remote control from the
ignition lock

Things to remember when driving
126 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 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 in
place for a long time by riding the clutch;
use the handbrake. Otherwise, greater clutch
wear will result.<
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
steep downhill stretches. Even light but consis-
tent pressure on the brake pedal can lead to
high temperatures, brake wear and possibly
even brake failure.<
The braking effect of the engine can be further
increased by downshifting, if necessary all the
way down into first gear. This strategy helps
you avoid placing excessive loads on the brake
system. For information on downshifting in the
manual mode of the sport automatic transmis-
sion, refer to page61.
Do not drive with the clutch depressed, in
idle or with the engine switched off, other-
wise there will be no engine braking action or
support of the braking force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants 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 respond with a pulsating
effect that even extended application will fail to
cure.
When vehicle is parked
Condensation forms in the automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.
