Automatic climate control
Comfortable interior climate
AUTO program7 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. All you need to do is
select an interior temperature which is comfort-
able for you.
The following sections inform you in detail
about how to adjust the settings.
Most settings are stored for the remote control
currently in use, refer also to Personal Profile
settings on page26.
Adjusting air distribution manually
The air distribution can be
switched on and off manually. The
air is directed to the windshield, to
the upper body area and to the
footwell. Automatic air distribution adjustment
is deactivated.
The current setting is briefly displayed on the
Control Display when a button is pressed.
You can switch the automatic air distribution
back on by pressing the AUTO button. This
automatically switches on the cooling function.
Temperature
Set the desired temperatures indi-
vidually for the driver's and front
passenger's sides.
The automatic climate control
achieves this temperature as quickly as possi-
ble regardless of the season, using maximum
cooling or heating power if necessary, and then
maintains it.
When you switch between different tem-
perature settings in quick succession, the
automatic climate control does not have
enough time to achieve the set temperature.<
You can achieve maximum heating power with
the highest setting, regardless of the outside
temperature.
The lowest setting effects continuous cooling.
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.
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
them for maximum cooling.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and
side windows, towards the upper
body area and into the footwell for you. The air
flow rate and your temperature specifications
will be adapted to outside influences as a result
of seasonal changes, e.g. sunlight or window
condensation.
The cooling is switched on automatically with
the AUTO program.
Intensity of the AUTO program
Press the AUTO button repeatedly to set the
intensity of the AUTO program. The current
setting is displayed on the Control Display
when the button is pressed.
Select the intensity of the AUTO program:
>−Low
>−Medium
>−High
Convertible program
The Convertible program is active when the
hardtop is open and the AUTO program is
switched on. In the Convertible program, the

automatic air conditioning system is optimized
for driving with the top 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 airflow. Press the right side
of the button to increase it.
You can reactivate the automatic mode for the
air flow rate with the AUTO button.
The air flow rate may be reduced or the blower
may be switched off entirely to save on 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 REST or rear window
defroster to reactivate the automatic climate
control.
The recirculated-air mode is switched on
when you switch off the automatic cli-
mate control. If the air quality deteriorates or the
window fogs over, switch the system back on
and increase the air volume.<
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 the 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 car will deteriorate contin-
uously.<
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 the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, the air flow rate and the air distri-
bution.
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.

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

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

Under the hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are unfamiliar with the statutory guide-
lines, have any work on the vehicle performed
only by a BMW center or by a workshop that
work according to BMW repair procedures with
correspondingly trained personnel. If this work
is not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<
Hood
Releasing
Pull the lever.
Opening
In order to avoid damage, make sure that
the wiper arms are against the windshield
before you open the hood. Do not open the
engine hood before the engine has cooled
down, otherwise injuries may result.<
Press the release handle and open the hood.
Closing
Let the hood drop from a height of approx. 10 in/
25 cm. It must be clearly heard to engage.
Make sure that the closing path of the
hood is clear, otherwise injuries may
result.
If you see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely.<

Care
214 When using high-pressure washers, do
not spray against the sensors and cam-
eras, e.g. of the Park Distance Control or Rear
View Camera, for an extended period and main-
tain a distance 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 unintentional 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.<
Wiper blades
Clean with soapy water and replace regularly to
avoid streaking.
Wax and preservative residue and con-
tamination on the window can lead to
streaking when operating the windshield wip-
ers, leading to premature wear of the wiper
blades and causing the rain sensor to malfunc-
tion.<
Convertible: retractable hardtop
Proceed as you would in a normal car wash.When you open a wet 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 very aggressive sub-
stances, e.g. spilled fuel, oil, grease, tree resin
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, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.
Preservation
A preservation treatment is necessary when
water no longer beads off of the clean paintwork
surface. Only use products for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-containing care prod-
ucts on rubber seals, otherwise noise and
damage could occur.<
Chrome parts
Carefully clean vehicle parts, such as the radia-
tor grill, door handles or window frames, with
copious quantities of water and a shampoo

neath the cover on the right-hand side of the
cargo bay, refer to page217.
Convertible: it is stored in the onboard tool kit
underneath the cargo bay floor, refer to
page217.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing on paved roads only. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting. Otherwise the tow
fitting and the vehicle could be damaged.<

Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer to
page58.
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts, otherwise dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
