Starting engine
Do not run the engine in enclosed areas,
otherwise the inhalation of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, 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
parking brake, 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 or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed.
Manual transmission
Remote control in ignition lock or with Comfort
Access in vehicle, refer to page34.1.Depress brake pedal.
2.Depress the clutch pedal and shift into
idling position.
3.Press the Start/Stop button.
Sport automatic transmission*
Remote control in ignition lock or with Comfort
Access in vehicle, refer to page34.
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 parking brake, 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 parking brake.
4.Remove the remote control from the igni-
tion lock, refer to page56.
Sport automatic transmission*
1.Shift transmission into position P with the
vehicle stopped.
2.Press the Start/Stop button.
3.Firmly apply the parking brake.
4.Remove the remote control from the igni-
tion lock, refer to page56.
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
control 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:

Things to remember when driving
120 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 page199.
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 pranking brake on inclines
On inclines, do not hold the vehicle in
place for a long time by riding the clutch;
use the parking brake. 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 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 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 can lead to high tem-
peratures, 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 page59.
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 air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
