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 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, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
select position P on the selector lever and
engage the parking brake before leaving the
vehicle with the engine running. Note the infor-
mation provided on the Info Display.<
1.Depress brake pedal.
2.Briefly press the Start/Stop button.
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.

Special starting conditions
In the following situations, press the gas pedal
halfway down when starting:
>The engine fails to start on the first attempt,
for instance if it is very hot or cold.
>The engine is being started at extremely low
temperatures below + 57/– 156, or at
high altitudes above 3,281 ft/1,000 m.
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.<
Switching off engine
When leaving the vehicle, always take the
remote control with you.<
With the vehicle stationary, briefly press the
Start/Stop button. Radio ready state is switched
on.
The transmission automatically shifts to
position P: interlock.
Before driving into a car wash
The transmission remains in position N and the
vehicle can roll when you perform the following
sequence:
1.With Comfort Access: insert remote control
into ignition lock.
2.With the engine running, shift transmission
into position N.
3.Switch engine off.
4.Leave the remote control in the ignition
lock.
The transmission will shift into position P:
>automatically after approx. 30 minutes
>if you remove the remote control from the
ignition lock
Observe the messages on the Info Display.
Removing remote control from ignition
lock
Press in the remote control briefly; it pops part-
way out. This procedure will also switch off the
ignition if it is on.
Comfort function
To switch off the engine when the vehicle is sta-
tionary, press the Start/Stop button for longer
than approx. 2 seconds. The remote control
pops partway out.
Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake.
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked.
You can use the parking brake in two ways:
>Manually, by briefly pressing the button
>Automatically, by activating the Automatic
Hold mode, refer to page59.
An electrohydraulic mechanism then engages
the parking brake to prevent the rear wheels
from turning whenever you switch off the
engine.
When the engine is running, parking brake
engagement is controlled by the brake sys-
tem's hydraulic circuits, which act on the disc
brakes in the front and rear wheels.
Brake pedal feel
The hydraulic brake system can produce a
slightly different braking feel. Engagement may
also be accompanied by activation noise – this
is normal.

Interior and exterior mirrors,
automatic dimming feature*
Two photocells in the interior rearview mirror
control this function. One is integrated into the
mirror's lens, the other is located offset from
this on the rear of the mirror housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of stickers to the windshield
in front of the mirror either.
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 only at walk-
ing speed at the most. Otherwise, you run the
risk of damaging the vehicle's engine, electrical
systems, 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 brake failure.<
You can further enhance the engine's braking
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 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 minimal
pressure that must be exerted by the pads dur-
ing brake applications to clean the rotors is not
reached.

Fuel specifications
Do not use leaded gasoline; otherwise,
permanent damage to the catalytic con-
verter will result.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with a
lower AKI rating. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems,
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.<
