Ventilation in the rear
1Use the knurled wheel to smoothly open
and close the air vents
2Use the knurled wheel to adjust the temper-
ature:
>Turn toward blue: colder
>Turn toward red: warmer
3Use the lever to change the direction of the
airflow
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
during parked car operation.
The parked car ventilation remains switched on
for 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
not be switched on twice in a row without driv-
ing in between to allow the battery to recharge.The air emerges from the air vents for the upper
body area in the instrument panel. The air vents
must therefore be open.
The parked car ventilation system is operated
via iDrive.
Switching on/off directly
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".
3.Select "Parked car operation" and press the
controller.
4.Select "Automatic ventilation" and press
the controller.
5.Select "Parked car ventilation" and press
the controller.
The parked car ventilation is switched on.
The symbol on the automatic climate control
display flashes.
Preselecting switch-on times
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".
3.Select "Parked car operation" and press the
controller.
4.Select "Activation time" and press the con-
troller.

have elapsed, it must be reactivated.<

Things to remember when driving

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed an engine speed of 5,500 rpm or a
road speed of 105 mph/170 km/h.
Do not depress the accelerator all the way.
From 1,200 miles/2,000 km to
3,000 miles/5,000 km
Engine and road speeds can be increased grad-
ually up to a traveling speed of 135 mph/
220 km/h. Use the maximum speed only for
brief intervals, e. g. when passing.
Transmission
The transmission begins functioning at an opti-
mal level only after a distance of approx.
300 miles/500 km. Do not exceed engine
speeds of 5,500 rpm during this period.
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 cautiously 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. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Clearance
Mind the limited clearance of the BMW
M3, e. g. when driving into underground
parking garages or over obstacles. If equipped
with EDC
*, select the "Sport" program, refer to
page84, when driving off curbs to keep clear-
ance as even as possible. Otherwise the vehicle
may be damaged.<
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle.<
If the vehicle must be driven with the luggage
compartment lid open:
1.Close all windows and the glass roof.
2.Greatly increase the air volume of the auto-
matic climate control system, refer to
page98.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-

Telephoning
184 >Selecting stored phone numbers, e.g. from
the list of accepted calls
>Ending a call
When the ignition and radio readiness are
switched off, e.g. after taking the remote control
out of the ignition switch, you can continue an
ongoing call via the hands-free system for no
more than 25 minutes.
Voice quality
If the person you are talking to is having difficul-
ties understanding you, this may be due to
excessive background noise. The full mobile
phone preparation package can compensate
for these noises to a certain extent. To optimize
voice quality during a call, we recommend that
you:
>Reduce background noise, e.g. by closing
the windows, reducing air flow from the
automatic climate control or by pointing the
open front air vents downward
>Reduce the volume of the hands-free sys-
tem
Requirements
>The mobile phone's pairing data are stored
by the vehicle and the mobile phone is oper-
ational.
>The engine is running or the ignition is
switched on.
>The mobile phone is recognized by the
vehicle.
Calling up communication
Many of the functions described below are con-
trolled using the "Communication" menu.
iDrive, for operating principle refer to page16.1.Press the button to call up the start
menu.
2.Move the controller forwards to call up
"Communication".
Receiving calls
If you have the phone number of the caller
stored in the phone book and the phone num-
ber has been transmitted, the name of the entry
is displayed.
Accepting a call
Press the button on the steering wheel.
Alternatively:
"Accept" is selected.
Press the controller.
Rejecting a call
Select "Reject" and press the controller.
The caller is diverted to your mailbox if it has
been activated.

Wheels and tires

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 100 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Z = over 150 mph/240 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT … 0708 means that the
tire was manufactured in week 7 of 2008.BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g.
