Active seat ventilation*
The system progresses one step through the
control sequence each time you press the but-
ton.
To switch off: press the button longer.
The highest position with three LEDs is
used for rapid cooling, e.g. when the vehi-
cle has gotten heated up. After a short time, the
system is automatically switched down one
position in order to prevent excessive cooling.<
Active seat*
The seat cushion is actively varied by alter-
nately raising and lowering the right and left half
of the seat cushion. This reduces muscular ten-
sion and fatigue to help prevent lower back
pain.
Press the button to switch on; the LED lights
up.
If you switch off the active seat, it can take up
to 1 minute before the two halves of the seat
cushion have returned to their initial position.
Mirrors
Exterior mirrors
The mirror on the passenger's side is
more curved than the driver's mirror.
Objects reflected in the mirror are closer than
they appear. Do not estimate the distance of
following traffic based on what you see in the
mirrors, otherwise there is an increased acci-
dent risk.<

2Switching to the other mirror or to the auto-
matic parking function
Storing the mirror positions, refer to Seat, mir-
ror and steering wheel memory on page47.
Manual adjustment
You can also adjust the mirrors manually by
pressing against the outer edges of their mirror
glass.
Folding mirrors in and out
To prevent the exterior mirrors on this
vehicle from being damaged, always fold
them in by hand before entering an automatic
car wash.<
Automatic heating
Below a certain outdoor temperature, both
exterior mirrors are automatically heated when
the motor is running or the ignition is switched
on.

Climate
106 The current setting for air distribution is dis-
played on the Control Display.
A congenial climate
The AUTO program offers the optimum air dis-
tribution and air volume for virtually all condi-
tions, refer to AUTO program below. Now you
only need to select an interior temperature
pleasant to you.
The following sections contain more detailed
information on the available setting options.
Most settings are stored for the remote control
currently in use, also refer to Personal Profile
settings on page29.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the air volume. It also adapts
your instructions for the temperature to outside
influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program in such
a way that window condensation is prevented
as much as possible.
Intensity of AUTO program
To meet your individual needs, you can weaken
or strengthen the intensity of the automatic cli-
mate control.
iDrive, for explanation of principle, refer to
page16.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".3.Select "Automatic programs" and press the
controller.
4.Select the desired intensity and press the
controller.
The marked intensity of the automatic
program is switched on.
Temperature
Set the desired temperature indi-
vidually on the driver's and front
passenger side.
The automatic climate control
adjusts this temperature as quickly as possible
at any time of year, if necessary with the maxi-
mum cooling or heating capacity, and then
keeps it constant.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to adjust the set temperature.<
Adjusting temperature in upper body
region
1.Open the start menu.
2.Open "Climate".
3.Select "Vent settings" and press the con-
troller.

Switching cooling function on and off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati-
cally with the AUTO program. The passenger
compartment can only be cooled with the
engine running.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible from an outside
temperature above 327/06 and
with the engine running.
The automatic climate control changes over to
the lowest temperature and switches into the
recirculated-air mode. The maximum air quan-
tity only flows out of the vents for the upper

Climate
108 body. Therefore, open these vents for maxi-
mum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to pollutants or
unpleasant odors in the immediate
environment by suspending the
supply of outside air. The system then recircu-
lates the air currently within the vehicle. During
AUC operation, a sensor detects pollutants in
the outside air and controls the shut-off auto-
matically.
By pressing the button repeatedly, you can
request three operating modes:
>LED off: outside air flows in continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
>Left LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
over an extended period of time, as the air qual-
ity inside the vehicle deteriorates continu-
ously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>with engine at operating temperature
>with sufficient battery voltage
>at an outside temperature below 777/
256The LED lights up when the function is
switched on.
From radio readiness the interior temperature,
the air volume and the air distribution can be
set.
Switching off automatic climate control
The air volume, the heater and the
cooling function are all switched
off.
You can restart the automatic cli-
mate control by pressing any of its buttons
except the REST button.
Front ventilation
1Knurled wheels to smoothly open and close
air vents
2Levers to change the air vent direction
Do not drop any foreign objects into the
vent outlets, otherwise these could be
catapulted outwards and lead to injuries.<
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance, if the interior
has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.

Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the SAE grades
5W-40 and 5W-30.<
These oils can be used for driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is comprised of water and coolant addi-
tive. Not all commercially available additives are
suitable for your BMW. Ask your BMW center
for suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.3.The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent to the
filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.
Brake system
Malfunctions
Brake fluid
The warning lamp lights red up in spite
of the handbrake being released; a
message is shown on the Control Dis-
play: stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system thoroughly
checked.
Display of the previously described
malfunction on Canadian models.
When you continue driving, an increased
brake pedal path can be necessary, and
significantly longer braking distances might be
required. Please adapt your driving style
accordingly.<
