Automatic climate control
Comfortable interior climate
AUTO program7 offers the ideal air distribution
and air flow rate for practically all conditions,
refer to AUTO program below. All you need to
do is select an interior temperature which is
comfortable 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 page29.
Adjusting air distribution manually
Direct the flow of air to the win-
dows, to the upper body area or to
the footwell.
You can switch the automatic air
distribution back on by pressing the AUTO but-
ton.
Manual fine adjustments in air
distribution
You can set the rate of incoming airflow for
manual air distribution.
iDrive concept, refer to page16.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to call up "Cli-
mate".
3.Select "Vent settings" and press the con-
troller.
4.Select the desired area.5.Turn the controller to set the air distribution
individually.
1Airflow directed toward the windshield and
side windows
2Air to the upper body area
3Air to the footwell
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.
Avoid switching the automatic climate
control system frequently from very low
to very high temperatures and vice versa. When
changes are made quickly in succession, the
automatic climate control does not have
enough time to achieve the set temperature.<
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 switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. For this
reason you should ensure that these vent out-
lets are open before selecting this program.
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.

2.Call up "Climate".
3.Select "Automatic programs" and press the
controller.
4.Select the desired area.
5.Press the controller to set the desired inten-
sity.
The selected intensity level of the auto-
matic program is switched on.
Adjusting air flow rate manually
Press the left side of the button to
reduce airflow. Press the right side
of the button to increase it. You can
reactivate the automatic mode for the air flow
rate with the AUTO button.
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 indicators go out.
Press any button except REST to reactivate the
automatic climate control.
AUC Automatic recirculated-air
control/Recirculated-air mode
Set the desired operating mode by
pressing this button repeatedly:
>LEDs off: outside air flows in
continuously.>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
You can activate/deactivate the recirculated-air
mode by means of a freely programmable but-
ton
* in the steering wheel, refer to page11.
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
over an extended period of time, as otherwise
the air quality inside the car will deteriorate con-
tinuously.<
Using residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
You can use this function for up to 15 minutes
after switching off the engine if it is warm and
the battery is sufficiently well charged. The out-
side temperature must be below 777/256.
The LED in the button comes on if these condi-
tions are met and the function is activated.
Defrosting windows and removing
condensation
This program quickly removes ice
and condensation from the wind-
shield and front side windows.
When the program is switched on, the LED
comes on.

Switching the cooling function on and
off
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is only available when the
engine is running and is switched on automati-
cally with the AUTO program.
Rear window defroster
When the rear window defroster is
switched on, the LED comes on.
The defroster switches off auto-
matically after a certain time.

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.
You can call up further information in the service
requirements display, refer to page69.

Practical interior accessories
94 The corresponding memory button 1 is now
programmed with the signal of the original
hand-held transmitter.
You can operate the system when the engine is
running or when the ignition is switched on.
If the system fails to function even after
repeated programming, check whether
the original hand-held transmitter uses an alter-
nating-code system. To do so, either read the
instructions for the original hand-held transmit-
ter or hold down the programmed memory
button1 of the integrated universal remote
control. If the LED2 on the integrated universal
remote control flashes rapidly for a short while
and then remains lit for about two seconds, the
original hand-held transmitter uses an alternat-
ing-code system. If it uses an alternating-code
system, program the memory buttons1 as
described under Alternating-code hand-held
transmitters.<
Alternating-code hand-held
transmitters
To program the integrated universal remote
control, consult the operating instructions for
the device to be set. You will find information
there on the possibilities for synchronization.
When programming hand-held transmitters that employ an alternating code, please observe
the following supplementary instructions:
Programming will be easier with the aid of
a second person.<
1.Park your vehicle within the range of the
remote-controlled device.
2.Program the integrated universal remote
control as described above in the section
Fixed-code hand-held transmitters.
3.Locate the button on the receiver of the
device to be set, e.g. on the drive unit.
4.Press the button on the receiver of the
device to be set. After step 4, you have
approx. 30 seconds for step 5.
5.Press the programmed memory button1 of
the integrated universal remote control
three times.
The corresponding memory button 1 is now
programmed with the signal of the original
hand-held transmitter.

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
Up to 1,250 miles/2,000 km:
Attempt to vary both engine and vehicle
speeds, but refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100 mph or 160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
Once you have driven 1,250 miles/2,000 km,
the engine and vehicle speeds can be gradually
increased.
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. Drive with caution 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
Closing the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is completely
closed. Otherwise, exhaust fumes could enter
the interior of the vehicle.<
If special circumstances make it absolutely nec-
essary to drive with the luggage compartment
lid open:
1.Close all windows and the glass sunroof.
2.Increase the air flow rate of the automatic
climate control considerably, refer to
page91.
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, with the risk of serious personal injuries and
property damage.<
Portable phone in the vehicle
BMW discourages the use of mobile
communications devices, e.g. portable
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<

Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
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 actually lose contact
completely with the road surface, so that nei-
ther 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 page177.
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.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Also use the drive-off assistant, refer to
page80.
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 pedal 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. Down-
shifting in manual mode of the automatic trans-
mission, refer to page52.
Never drive with the clutch pedal held
down, with the gearshift lever or selector
lever in neutral or with the engine switched off;
engine braking action will not be present with

Things to remember when driving
108 the transmission in neutral and there will be no
power assistance to the brakes or steering
while the engine is switched off.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct their
movement.<
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
during brake applications to clean the rotors is
not reached.
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.
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.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
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. The ultimate result
can assume the form of a sudden blow-out.<
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 lbs.
passengers in your vehicle, the amount of
available 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.
