Ignition lock
Insert the remote control all the way into the
ignition lock. Radio ready state is switched on.
Individual electrical devices are ready for use.
Start/Stop button
Briefly pressing the Start/Stop button several
times switches the radio ready state or the igni-
tion on and off.
Briefly pressing the Start/Stop button
with the brake pedal depressed starts the
engine.<
Radio ready state
Individual electrical devices are ready for use.
The time and outside temperature appear on
the Info Display.
Ignition switched on
All vehicle systems are ready for operation.
When the engine is not running, please
switch off the ignition and nonessential current-consuming devices in order to mini-
mize the drain on the battery.<
Ignition off
All of the indicator lamps on the Info Display go
out. Only the selector lever indicator of the
automatic transmission is still briefly displayed.
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
move the selector lever into position P and
engage the parking brake before leaving the
vehicle with the engine running.<
Avoid frequent starts in rapid succession
or repeated starting attempts in which the
engine does not start. Otherwise, the fuel is
either left unspent or is insufficiently burned
and there is a risk of overheating and damaging
the catalytic converter.<
1.Depress brake pedal.
2.Briefly press the Start/Stop button.
When starting the engine, do not press the
accelerator pedal.

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 tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Only drive through water with a maximum
depth of 1 ft/30 cm and then, at no more
than walking speed. Otherwise, you run the risk
of damaging the vehicle's engine, electrical sys-
tems, and transmission.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations that require it, it is best
to apply the brakes fully. Since the vehicle
maintains steering responsiveness, you can
nevertheless 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.
Driving in wet conditions
When driving in wet conditions and 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 endanger other road users. The heat gener-
ated 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 reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear that requires
the least amount of braking. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear, and possibly
even failure of the brake system. action by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page63. This strategy helps you avoid
placing excessive loads on the brake system.
Do not drive in idle or with the engine
switched off; otherwise, there will be no
engine braking action or power-assist for the
brakes 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 minimal
pressure that must be exerted by the pads dur-
ing 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.
Before driving into a car wash
1.Fold in the exterior mirrors, refer to page50;
otherwise, they could be damaged due to
the width of the vehicle.
To permit the vehicle to roll, follow the
instructions on page58.
2.Release the parking brake, especially when
you have activated Automatic Hold. Refer to
page59.
