Ventilation
1Serrated dial for smoothly opening and
closing air vents
2Lever for changing the airflow direction
Do not drop any foreign bodies into the
vent outlets, as 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.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
center replaces this combined filter as a stan-
dard part of your scheduled maintenance.
You can have more detailed information shown
on the Control Display, refer to page70.

Integrated universal remote
control*
The concept
The integrated universal remote control
replaces up to three different hand-held trans-
mitters for various items of radio-controlled
equipment such as door openers and house
alarm systems. The integrated universal remote
control registers and stores signals from the
original hand-held transmitters.
The signal of an original hand-held transmitter
can be programmed into one of the three mem-
ory buttons1. Then the respective device can
be actuated using the memory button1 pro-
grammed for its use when the ignition key is in
position 2. The LED2 flashes to confirm trans-
mission of the signal.
If you sell your vehicle one day, delete the saved
programs beforehand for your own security,
refer to page101.
To prevent possible damage or injury,
before programming or using the inte-
grated universal remote control, always inspect
the immediate area to make certain that no peo-
ple, animals or objects are within the travel
range of the device. Also comply with the safety
precautions of the original hand-held transmit-
ter.<
Checking compatibility
If you see this symbol on the packaging
or in the manual supplied with the orig-
inal hand-held transmitter, it is safe to
assume that it is compatible with the integrated
universal remote control.
If you have additional questions, please consult
your BMW center or call 1-800-355-3515.

Programming
1Memory buttons
2LED
Fixed-code hand-held transmitters
1.Ignition key in position 2.
2.When using for the first time: press both
outer buttons 1 for approx. 20 seconds,
maintaining pressure until the LED 2 starts
to flash. The three memory buttons1 are
cleared.
3.Hold the original hand-held transmitter at a
distance of approx. 2 in/5 cm to 8 in/20 cm
to the memory buttons1.
The required distance between the
hand-held transmitter and the mem-
ory buttons1 depends on the respective
system of the original hand-held transmitter
used.<
4.Simultaneously press the transmit button
on the original hand-held transmitter and
the desired memory button1 on the inte-
grated universal remote control. Initially, the
LED2 flashes slowly. Release both buttons
as soon as the LED 2 flashes rapidly. If the
LED2 does not flash rapidly after approx.
15 seconds, change the distance.
5.To program other original hand-held trans-
mitters, repeat steps 3 and 4.
The corresponding memory button1 is now
programmed with the signal of the original
hand-held transmitter.

Things to remember when driving
108
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.<
