Radio readiness and ignition off
All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
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, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral and forcefully
apply the parking brake to prevent the car from
moving.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not 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.

Reverse gear
Select this only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.
M dual clutch transmission
with Drivelogic*
The concept
The M dual clutch transmission with Drivelogic
is an automated manual transmission with two
clutches and a partial transmission in which an
electro-hydraulic system takes over clutch
action and shifting.
With the M dual clutch transmission, gears are
changed without interruption of the traction
force.
The M dual clutch transmission is operated
using the selector lever and two shift paddles
on the steering wheel.
The transmission offers you the following func-
tions:
>Selection between manual or automatic
operation, sequential mode or drive mode
>Selection between different drive pro-
grams, Drivelogic, refer to page61
>Shift Lights, refer to page62
>Automatic downshifting and protection
against selecting the wrong gear even in
sequential mode
>Launch Control, refer to page63
>Automatic throttle blip
>Low Speed Assistant
System limitations
The M dual clutch transmission is equipped
with an overheating protection system that pro-
tects the clutch against extreme loads.
The indicator lamp lights up yellow
when the transmission becomes too
warm. Avoid high engine loads and
driving off frequently. When the transmission is
overheated, the indicator lamp lights up red and
the fuel supply to the engine is cut off. You can-not continue driving until the transmission has
cooled down.
Avoid driving off frequently with high accelera-
tion and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.
In traffic congestion or at very low speeds, use
the Low Speed Assistant, refer to the informa-
tion below.
Low Speed Assistant
The Low Speed Assistant supports you when
driving at very low speeds: the vehicle moves at
walking speed and automatically controls the
engine speed. You can also use the Low Speed
Assistant when rocking the vehicle out of deep
snow. To do so, shift between reverse gear and
the forward position without pressing the brake.
Activating
1.Engage a drive position.
2.Briefly tap the accelerator.
The vehicle rolls at the minimum speed.
Do not press the brake continuously as
this may cause the transmission to over-
heat.<
Deactivating
Brake the vehicle to a stop to deactivate the
Low Speed Assistant.

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
as well.
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

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
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.

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 hot exhaust pipes, e. g.
when loading the cargo bay, otherwise there is a
risk of burn injuries.<
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.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page199.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise greater clutch
wear will result.<
For more information about the drive-off assis-
tant, refer to page84.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system.
M dual clutch transmission: never drive
with the transmission in neutral or with
the engine switched off; otherwise, engine
braking action will not be present or there will be
no power assistance to the brakes or steering.
Manual transmission: never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
engine braking action will not be present or
there will be no power assistance to the brakes
or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
ba8_E9293M3_cic.book Seite 117 Dienstag, 19. August 2008 12:01 12

Things to remember when driving
118 during brake applications to clean the rotors is
not reached.
This can also lead to a permanent loss in ride
comfort and to squealing noises during braking.
A loss in comfort can also be caused by
extended braking with little pressure on the
pedal.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
For information on brake system technology,
refer to Compound brake on page121.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. This can ultimately
result in a sudden blow-out.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
bay, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
