Switching the cooling function
on and off
The cooling function cools and
dehumidifies the incoming air
before reheating it as required,
according to the temperature set-
ting. This function is only available while the
engine is running.
The cooling function he lps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weathe r, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program.
Maximum cooling
Maximum cooling is achieved most
quickly at outside temperatures
above 32 7/06 and when the
engine is running.
The automatic climate control goes into recir-
culated-air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open the
vents for maximum cooling.
AUTO program
The AUTO program auto matically adjusts the
air distribution to the windshield and side win-
dows, towards the upper bo dy area, and into the
footwell and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influenc es as a result of sea-
sonal changes, e.g. sunlight or window conden-
sation.
The cooling is switched on automatically with
the AUTO program.
Switching on/off
Press the button.
Manual air distribution and air flow rate are acti-
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the inten-
sity when the AUTO program is switched on.
For example, air flow is adjusted automatically
to optimize climate control.
When the AUTO program is
switched on, you ca n select the cli-
mate level of the AUTO program
using the buttons for controlling the manual air
flow rate.
The selected climate le vel is displayed by
an LED.
Convertible program
When the hardtop is open, the convertible pro-
gram is activated as well. In the convertible pro-
gram, the automatic climate control is opti-
mized for driving with the hardtop open. In
addition, the air flow rate is increased as vehicle
speed increases.
The effectiveness of the convertible pro-
gram can be enhanced considerably by
installing the wind deflector. <
Adjusting air flow rate manually
Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it.
The air flow rate may be reduced to save battery
power. The display remains the same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All displays are cleared
except for the rear window defroster if it is
switched on.
Press any button except the rear window
defroster to reactivate the automatic climate
control.

Automatic recirculated-air control
AUC/recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
> LED off: outside air flows in continuously.
> Left-hand LED on, AUC mode: a sensor
detects pollutants in th e outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
> Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
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 flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the ca r will deteriorate contin-
uously. <
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
Rear window defroster
The defroster switches off auto-
matically after a certain time or
when the hardtop is opened.
Ventilation
1 Lever for changing the direction of the
air flow.
2 Knurled wheels for opening and closing the
air vents.
3 Knurled wheel for adju sting the amount of
cool air from the vents to the upper body
area. In this way you can optimize the air
temperature 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.
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 outs ide air. Your BMW cen-
ter replaces this combined filter during routine
maintenance.

access to the stored items.
Only place clean skis in the transport bag. Wrap
sharp edges to prevent damage.

Things to remember when driving
114
Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the cargo bay partition,
and as low as possible.
> Cover sharp edges and corners.
Cargo, securing
Secure smaller and lighter items using retaining
straps, a cargo bay net
* or draw straps*.
Heavy-duty cargo straps
* for securing larger
and heavier objects are available at your BMW
center. Four lashing eyes are provided behind
the seats for attaching the cargo straps.
Adhere to the informat ion included with the
cargo straps.
Always position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the a pproved axle loads, refer
to page 222, as excessive loads can pose a safety hazard, and may al
so place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants. <
Before opening the hardtop, fold down
the cargo bay partition. Make sure the
cargo bay is loaded correctly, otherwise parts of
the hardtop can be damaged, refer to
page 105.<

Steam jets / high -pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 60°C.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer. <
When using high-pressure washers, do
not spray against the seals of the retract-
able hardtop, the sensor s and the cameras, e.g.
of the Park Distance Control or Rear View Cam-
era, for an extended period and maintain a dis-
tance of at least 12 in/30 cm. <
Manual car wash
When washing the vehicle by hand, use large
quantities of water and car shampoo if neces-
sary. Clean the vehicle with a sponge or wash-
ing brush, applying light pressure only.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion to prevent unintent ional activation of the
wipers. <
Observe local regulations pertaining to
washing vehicles by hand. <
Headlamps
Do not rub them dry and do not use abrasive or
corrosive cleaning agents.
Remove contamination, such as insects, by
soaking with shampoo or insect remover and
then rinsing with plenty of water.
Thaw ice with a windshield de-icer and do not
use an ice scraper.
Windows
Clean the inside and outside surfaces of the
windows and the mirrors with window cleaner.
Do not clean the mirrors with cleaners
containing quartz. <
Retractable hardtop
Proceed as you would in a normal car wash.
When you open a we t hardtop, water
drops may run into the cargo bay. If nec-
essary, remove items from the cargo bay
beforehand to avoid water stains or soiling. <
Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap or
bird droppings to prevent damage to the
paintwork.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, wher e necessary to prevent
rusting. <
BMW recommends having paintwork damage
repaired by a profession al paint repair work-
shop according to BMW specifications using
original BMW paint materials.
