Seat, mirror and steering wheel memory Seat heating
*
Your BMW center can adjust your
vehicle's systems in such a
manner that your personalized settings
are automatically called up for the seat,
mirror and steering wheel positions
when you unlock the vehicle with your
personal remote control key.<
Before using the key memory fea-
ture to unlock the vehicle always
ensure that no objects are stored in the
footwell behind the driver's seat. If you
fail to do so, persons or objects could
be injured or damaged if the seat
should move backward.<
Passenger-side exterior mirror tilt
function(automatic curb monitor)
1 Move the mirror selector switch
(arrow) to the "driver's mirror" posi-
tion
2 When the gearshift lever or the
selector lever is placed in "Reverse,"
the passenger-side mirror tilts down-
ward to help the driver monitor the
area directly adjacent to the vehicle
during parking (curbs, etc.).
You can deactivate this automatic fea-
ture by setting the mirror selector
switch to the "passenger-side" posi-
tion.390de720
The seat cushion and backrest can be
heated with the ignition key in
position 2.
You can select from different heating
modes by repeatedly pressing the
button.
You can also switch the higher heating
modes off directly:
Press the button and hold it slightly
longer.390us729

Adjusting steering wheel Steering wheel heating
*
The steering wheel can be moved in
any of four directions. Adjust by moving
the control lever in the desired direc-
tion.
Do not adjust the steering wheel
while the vehicle is moving. There
is a risk of accident from unexpected
movement.<
To store the steering wheel setting,
refer to "Seat, mirror and steering
wheel memory" on page 54.390de711
Automatic steering wheel
adjustmentIn order to make it easier to get into and
out of the vehicle, the steering wheel
automatically moves into the top posi-
tion and returns to the driving (memory)
position.
This automatic feature is controlled by
the position of the ignition key and by
the driver's door.
The steering wheel heating feature is
available for operation when the ignition
key is in position 2.
Press the button to switch on and off.
The lamp within the button lights up
when the steering wheel heating is in
operation.
If you have a multifunction steering
wheel without steering wheel heating,
the button for the recirculated-air mode
is in this location (refer to page 22).

OverviewControlsMaintenanceRepairsDataIndex
Air conditioningTemperature
The graduations on the dial
provide general reference
values for the interior temper-
ature. We recommend 70 7
(22 6) as a comfortable setting. When
you start the vehicle, this system
adjusts the air to the selected tempera-
ture as quickly as possible, and then
maintains that temperature constantly.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are also available. In
the setting, there is a low flow of air
onto the windows to keep them free of
condensation.
Air supply
You can control the emerging
air's flow rate through an infi-
nitely-variable range. The
heating and ventilation
become more and more effective as the
air supply settings are increased. In the
"0" setting, the blower and climate con-
trol are switched off and the outside air
supply is blocked.
Rear window defroster
The indicator lamp comes
on to indicate that the rear
window defroster is in operation. The
rear window defroster switches off
automatically.
Cooling
The air conditioning cools
and dehumidifies the
incoming air before reheating it to the
selected temperature. Depending on
the weather, the windshield may fog
over briefly when the engine is started.
You can reduce condensation forming
on the windows by switching on the air
conditioning.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to
unpleasant odors in the sur-
rounding environment by using this
mode to temporarily suspend the flow
of outside air into the vehicle's interior.
The system then recirculates the air
currently within the vehicle.
If your vehicle is equipped with a multi-
function steering wheel
featuring a
recirculated-air button then you can
also select the recirculated-air mode
from this location (refer to page 22).
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.<

Tips for pleasant drivingUse the automatic system, that is,
press AUTO button 6. Select an interior
temperature that you find comfortable.
Detailed setting options are described
for you in the following section.
Your BMW center can program
the settings of your vehicle in such
a manner that, when you unlock the
vehicle with your individualized key,
your own personalized setting for the
automatic climate control is initiated.< Automatic air distribution
The AUTO program
assumes the adjustment of
the air distribution and the air supply for
you and also adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify.
Individual air distribution
You can cancel the AUTO
program by selecting
specific distribution patterns
to suit your own individual
requirements. While the
AUTO program is then deactivated, the
automatic airflow control remains in
operation. The system directs air to the
windows , the upper body and
into the footwells . You can reacti-
vate the automatic air distribution mode
by selecting the AUTO button.
Temperature
You can make individual
temperature settings on the
driver's side or the front
passenger side. Your selection appears
in display 7. The numbers that appear
in the display are reference figures for
interior temperature. We recommend a
setting of 72 7 (22 6) for a congenial
interior climate, even when the air con-
ditioner is in operation. When you start
the vehicle, the system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Air supply
AUTO appears in
display 9, while the AUTO
program automatically controls the flow
of incoming air, refer to overview on
page 109. You can use "+" and "Ð" to
vary the airflow. When your setting is
displayed by bars, the automatic airflow
is switched off. Automatic air distribu-
tion maintains its setting. You can reac-
tivate the automatic airflow by pressing
the AUTO button.
When you press "Ð " during operation at
minimum blower speed all displays are
canceled: the blower, heating and air
conditioner are switched off. The out-
side air supply is deactivated. By
pressing any button of the automatic
climate control (except the MAX
button 16), you can switch the system
back on.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.

Residual heating mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance).
In ignition key position 1, you can alter
the settings of the automatic climate
control. In ignition key position 0, the
system automatically directs heated air
to the windshield, side windows and
footwells.
This function is available for oper-
ation when the outside tempera-
ture is below approx. 59 7 (15 6),
with the engine warm from recent oper-
ation and an adequate charge in the
battery. The LED on the button will light
up when all conditions have been
met.<
Draft-free ventilationYou can adjust the vent outlets for the
upper body area completely for your
personal comfort:
1 Rotary dials for infinitely-variable
opening and closing of the vent out-
lets
2 Selector levers for airflow direction
3 Rotary dial allows you to control the
temperature of the airflow as desired:
>Turn toward blue Ð colder
>Turn toward red Ð warmer.390de685
Rear passenger area ventilation1 Rotary dial for infinitely-variable
opening and closing of the vent out-
lets
2 Selector levers for airflow direction
3 The rotary dial operates in the same
way as the front dial to adjust the
temperature of the emerging air.390de686
