Starting the engine
Do not run the engine in closed rooms,
otherwise the inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, otherwis e such a vehicle repre-
sents a potential safety hazard.
Before leaving the car wi th the engine running,
place the transmission in neutral or move the
selector lever to position P and set the parking
brake to prevent the car from moving. <
Avoid frequent starting in quick succes-
sion as well as repeat ed start attempts in
which the engine does no t start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter. <
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The
gear selected is briefly displayed in the instru-
ment cluster, followed by the gear actually
in use.
Shifting gears via sh ift paddles* on the
steering wheel
The shift paddles allow yo u to shift gears with-
out taking your hands off of the steering wheel.
> When you use the shift paddles on the
steering wheel to shif t gears in automatic
mode, the transmission switches to
manual mode.
> If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode.
If the selector lever is in the M/S gear
plane, manual mode remains active. <
> To shift up: pull one of the shift paddles.
> To shift down: press one of the shift
paddles.
Upshifts and downshifts are executed only

Overriding selector lever lock
Should the selector lever refuse to move out of
position P although the button on the selector
lever is pressed, the sele ctor lever lock can be
overridden:
1. Unclip the sleeve of the selector lever.
2. Pull the sleeve up over the selector lever
until the sleeve is inside out. 3.
Using the screwdriver from the onboard
tool kit, refer to page 208, press the red
lever while moving the selector lever to the
desired position.
7-gear sport automatic
transmission with dual
clutch*
The concept
This transmission is an automated manual
transmission with two clutches and two gear-
box components in which the gears are
changed without loss of torque.
You operate the transmission using the selector
lever and two shift paddles on the steering
wheel.
It offers the following functions:
> Selection between manual and automatic
operation: sequential mode or drive mode
> Automatic downshifting and protection
against selecting the wrong gear, even in
sequential mode
> Launch Control acceleration assistant, refer
to page 58
> Automatic double de-clutch
System limitations
This transmission is equipped with an over-
heating protection system that protects the
clutches against extremely high loads.

Air distribution
Direct the flow of air to the win-
dows , to the upper body area
or to the knee area and footwell
. Intermediate settings are pos-
sible. In the 6 o'clock position, a small amount
of air is also directed towards the windows in
order to keep them from fogging over.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off the supply to the interior of the car
temporarily. The system then recirculates the
air currently within the vehicle.
You can also activate/d eactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page 11.
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
continuously for lengthy periods, otherwise the
quality of the air inside the car will gradually
deteriorate. <
Air flow rate
Press the corresponding button.
The higher the rate, the more
effective the heating or cooling
will be.
The air flow rate may be reduced or the blower
may be switched off entire ly to save on battery
power.
Switching the system on/off
With the blower at its lowest set-
ting, press the left side of the but-
ton. Thes blower and air condi-
tioner are completely switched off and the air
supply is cut off.
To switch on the air cond itioner, set the desired
air flow rate.
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it as re quired, according to the
temperature setting. This function is only avail-
able while the engine is running.
The cooling function helps 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.

Comfortable interior climate
AUTO program 7 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 temp erature 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 al so to Personal Profile
settings on page 28.
Air distribution, manual
Depending on the selected setting, the air is
directed to the windshie ld, to the upper body
area, to the knee area and into the footwell.
Adjusting air distribution manually
Press the button repeatedly until
the air distribution is set as
required. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.
Temperature
Set the desired temperatures indi-
vidually for the driver's and pas-
senger'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.
To give the automatic climate control
enough time to achieve the set tempera-
ture, do not switch be tween different tempera-
ture settings in quick succession. <
You can achieve maximum heating power with
the highest setting, rega rdless of the outside
temperature.
The lowest setting effe cts continuous cooling.

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.

Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance to the forward vehicle. A defensive
and smooth driving style keeps fuel con-
sumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accele rate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable ge ar and drive with the
engine speed as low as possible and at a con-
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Coasting
When approaching a red lig ht, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
On a downhill slope, take your foot off the accel-
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engi ne during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestion. You achieve fuel sav-
ings even if standing time is as short as approx.
4 seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner and the
seat or rear window heating draw large amounts
of power and consume a dditional fuel. Espe-
cially in city traffic and in stop and go driving
they have a considerable impact. Therefore,
switch these functions off when they are not
really needed.
Have the vehicle serviced
Have the vehicle serviced regularly to achieve
good economy and a long vehicle life. BMW
recommends having the vehicle serviced at a
BMW center. Also note the BMW service sys-
tem, refer to page 202.
General driving notes
Close the luggag e 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.
2. Greatly increase the ai r volume of the auto-
matic climate control system, refer to
page 96.
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 sect ions of the exhaust sys-
tem, and never apply un dercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage. Do not touch ho t exhaust tail pipes.
Otherwise there is a risk of burns. <
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
