Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature setting. This
function is only available while the engine is
running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
Rear window defroster
The defroster is switched off auto-
matically after a certain time.
Depending on your vehicle's
equipment, the upper wires serve as an antenna
and are not part of the rear window defroster.
Ventilation
1Use the knurled wheels to smoothly open
and close the air vents
2Use the lever to change the direction of the
airflow
3Knurled wheel for more or less cool air from
the vents for the upper body area
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance if it has become
too hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
Ventilation in the rear
1Use the knurled wheel to adjust the temper-
ature
>Turn toward blue: colder
>Turn toward red: warmer
2Use the knurled wheel to smoothly open
and close the air vents
3Use the lever to change the direction of the
airflow
Microfilter/activated-charcoal filter
The microfilter traps dust and pollen in the
incoming air. The activated-charcoal filter pro-
vides additional protection by filtering gaseous
pollutants from the outside air. Your BMW cen-
ter replaces this combined filter during routine
maintenance.
Parked car ventilation
The concept
The parked car ventilation provides ventilation
to the passenger compartment and lowers its
temperature, if necessary. It is ready for use at
any outside temperature, as of radio readiness.
The parked car ventilation remains switched on
for approx. 30 minutes. Two different switch-on
times can be preselected. The system can also
be switched on and off directly.
Due to its high power consumption, it should

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW center.
Only change bulbs while they are cool to
the touch, otherwise you could suffer
burns.<
When working on electrical systems,
always begin by switching off the con-
sumer in question, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
For care of the headlamps, please follow the
instructions in the chapter entitled 'Care'.
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours, otherwise this could cause
irritation to the retina.<
Xenon lamps
These bulbs have a very long service life and are
highly unlikely to fail. If a xenon bulb fails never-
theless, switch on the fog lamps and continue
the journey with great care, provided that local
legislation does not prohibit this.
Have any work on the xenon lamp system,
including bulb replacements, performed
only by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
Access to the bulbs
1.Switch off the lamps and take the remote
control out of the ignition lock.
2.Remove the upper cover from the head-
lamp. To do so, use a screwdriver to press
the catches towards the rear, see arrows,
and pull the cover forward and out.
Follow the same steps in reverse order to reat-
tach the cover.
Be careful when installing the cover, oth-
erwise leaks could occur and cause dam-
age to the headlamp system.<
