The current setting for air distribution is dis-
played on the Control Display.
A congenial climate
For almost all conditions, the AUTO program
offers the optimal air distribution and air vol-
ume. Select an interior temperature you find
pleasant.
The following section contains more detailed
information on the available setting options.
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 adjustment of the air volume.
It also adapts your instructions for the tempera-
ture 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.
Temperature adjustment
By rotating, you can set a desired
temperature for the driver's side
and the passenger side.
After you start to drive, this system
ensures that the selected temperature is
achieved as quickly as possible. It then main-
tains this temperature, regardless of the sea-
son.
Defrosting windows and removing
condensation
This program quickly removes ice
and condensation from the wind-
shield and front side windows.
Air volume, manual
You can adjust the air volume by
turning. You can reactivate the
automatic mode for the air volume
with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before reheating it as needed
according to the temperature setting. Depend-
ing on the weather, the windshield may fog over
briefly when the engine is started.
The air conditioner can operate only when the
engine is running. The AUTO program auto-
matically switches on the air conditioner.
Maximum cooling
This program quickly provides
maximum cooling.
The system switches to the recir-
culated-air mode and the air flows
at maximum air volume only from the vent out-
lets for the upper body area. For this reason you
should ensure that these vent outlets are open
before selecting this program.
AUC automatic recirculated-air
control/recirculated air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LED off: outside air flows into the vehicle
continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Left LED on, recirculated-air mode: the
supply of outside air into the vehicle is shut
off continuously.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch

A congenial climate
96 it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Residual heat mode
Press the button when the motor is
switched off and warm.
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. when stopped at a school to pick
up a child.
You can adjust the automatic climate control
settings as of ignition key position 1.
Provided that the engine has warmed to its nor-
mal operating temperature and the battery is
charged, you can use this function for up to
15 minutes after switching off the ignition. The
LED in the button lights up to confirm compli-
ance with both of these conditions.
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.
Settings using Control Center

Things to remember when driving
Breaking-in
Moving parts need time to adjust to one
another. To ensure that your vehicle continues
to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Up to 1,200 miles/2,000 km:
You should attempt to vary both vehicle and
engine speeds. Until the break-in period has
been completed, you should also refrain from
exceeding an engine speed of 4,500 rpm or a
driving speed of 100 mph/160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
Once you have driven 1,200 miles/2,000 km,
the engine and vehicle speeds can be gradually
increased.
SMG Sequential manual transmission
Do not use the acceleration assistant during the
break-in period, refer to page59.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
After component replacement
You should also comply with these break-in
procedures should the components mentioned
above need to be replaced at a later point.
General driving notes
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed. Otherwise, exhaust fumes could pene-
trate to the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
luggage compartment lid open:
1.Coupe: close both windows and the glass
sunroof.
Convertible: with closed top, close all win-
dows.
2.Adjust the automatic climate control to sup-
ply a high air volume, refer to page95.
Hot exhaust system
As in all vehicles equipped with a catalytic
converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking, take care to avoid pos-
sible contact between the hot exhaust system
and any highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead to a
fire, and with it the risk of serious property dam-
age as well as personal injury.<

Towing and tow-starting
Always observe all applicable towing laws
and regulations.<
Never allow passengers to ride in a towed
vehicle for any reason.<
Use tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page180, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
To avoid damage to the tow fitting and the
vehicle, observe the following: only use
the tow fitting that comes with the vehicle and
screw it in as far as possible. Use the tow fitting
for towing only on roads. Avoid lateral strains on
the tow fitting, e.g. do not the lift vehicle by the
tow fitting.<
Access to screw thread
Rectangular cover in bumper:
Press the arrow symbol of the cover.

Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering wheel
could lock and it would be impossible to steer
the vehicle. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering. Active steering is
deactivated and larger steering wheel move-
ments are required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, as otherwise the automatic
transmission may be damaged.<
Vehicles with SMG Sequential manual
transmission
With the ignition switched on, engage selector-
lever position N, then switch off the ignition.
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
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 offset
angle, please observe the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.
