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.<
Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using an
individually programmable button
on the steer-
ing wheel, refer to page47.
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.
The function can be switched on when the fol-
lowing conditions are met:
>Up to 15 minutes after the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, the air flow rate and the air distri-
bution.
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.
The cooling function is automatically switched
on along with the AUTO program.
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.

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

What to do if …
>a navigation DVD is inserted, but an instruc-
tion to insert the DVD appears on the Con-
trol Display?
The navigation DVD may not be the correct
DVD for the navigation system. This infor-
mation is indicated on the DVD label.
>you request the current position of your
vehicle, but do not receive a precise dis-
play?
The system is unable to receive enough
GPS signals at your current position due to
obstructions, your current position is not
yet available on your navigation DVD, or the
system is in the process of calculating your
current position. As a rule, reception is
guaranteed when you are in the open.
>the destination guidance does not accept a
destination?
The data of the destination is not stored on
the navigation DVD that is loaded. Choose a
destination as close as possible to the orig-
inal one.
>the destination guidance does not accept
an address without the street name?
On the navigation DVD, no downtown area
can be determined for the city or town
entered. Enter any street, or a destination
such as the railway station in the selected
town, and then start the destination guid-
ance.
>you want to enter a destination for the des-
tination guidance, but it is not possible to
select the letters for your desired entry?
The data of the destination is not stored on
the navigation DVD that is loaded. In this
case, the system will not offer you any let-
ters to choose from. Choose a destination
as close as possible to the original one.
>the system stops furnishing directions on
which way to turn as you approach intersec-
tions?
You are driving in an area that has not yet
been completely recorded on the naviga-tion DVD. Instead of an arrow indicating a
turn, you will see an arrow which indicates
the general direction of your planned route.
Or you have left the recommended route
and the system requires a few seconds to
calculate a new recommended route.
>the navigation system does not react to
entries?
If the battery was disconnected, it takes
about 10 minutes before the system is once
again operational.

Telephoning
178
Telephoning
The concept
Your BMW is equipped with a full mobile phone
preparation package. After pairing a suitable
mobile phone with the vehicle once, you can
operate the mobile phone via iDrive, the buttons
on the steering wheel or via voice commands.
Once a mobile phone has been paired with your
vehicle, it is automatically recognized as soon
as it is inside the vehicle while the engine is run-
ning or the ignition is switched on. You can
store the pairing data for up to four mobile
phones simultaneously. If several mobile
phones are detected at the same time, the
mobile phone last paired can be operated via
the vehicle.
Using the telephone inside
the vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a holder for
mobile phones, allows you to charge the mobile
phone's battery and connect the mobile phone
to your vehicle's outside antenna. This ensures
better network reception and consistent repro-
duction quality. Please contact your
BMW center to find out for which mobile
phones there are snap-in adapters available.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate Owner's Manual for a detailed
description of safety precautions and informa-
tion, we request that you direct your particular
attention to the following:
Only make entries when the traffic situa-
tion allows you to do so. Do not hold the
mobile phone in your hand while you are driving;
use the hands-free system instead. If you do
not observe this precaution, your being dis-tracted can endanger vehicle occupants and
other road users.<
Suitable mobile phones
Please ask your BMW center which mobile
phones with Bluetooth interface are supported
by the mobile phone preparation package and
which mobile phones are compatible with the
snap-in adapter. By virtue of their particular
software versions, these mobile phones sup-
port the functions described in this Owner's
Manual. Malfunctions may occur with other
mobile phones.
Care instructions
Important information on this subject can be
found in the separate mobile phone Owner's
Manual.
Operating options
You can operate the mobile phone* using:
>Buttons on the steering wheel, refer to
page10
>iDrive, refer to page183
>Voice commands, refer to page189
>Programmable memory keys, refer to
page21
Avoid operating a mobile phone recognized by
the vehicle via the mobile phone's keypad, oth-
erwise malfunctions may result.
Making phone calls with the
BMW Assist system*: BMW Assist
calls
You can use the BMW Assist System via the
hands-free unit for BMW Assist calls.

Jump starting
If the car's own battery is flat, your BMW's
engine can be started by connecting two
jumper cables to another vehicle's battery. You
can also use the same method to help start
another vehicle. Only use jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Carefully adhere to the follow-ing sequence, both to prevent damage to one or
both vehicles, and to guard against possible
personal injuries.<
Preparation
1.Check whether the battery of the other
vehicle has a voltage of 12 volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any consumers in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
Connect the jumper cables in the correct
order, so that no sparks which could
cause injury occur.<
Your BMW has a jump-starting connection in
the engine compartment which acts as the bat-
tery's positive terminal, refer also to the Engine
compartment overview on page219. The cap is
marked with +.
1.Pull the cap of the BMW jump-starting con-
nection up to remove.
2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-aid terminal of the vehi-
cle providing assistance.
3.Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a starting-aid terminal of
the vehicle to be started.

Giving and receiving assistance
232 4.Attach one terminal clamp of the minus/–
jumper cable to the negative terminal of the
battery or to an engine or body ground of
the assisting vehicle.
Your BMW has a special nut as body ground
or negative pole.
5.Attach the second terminal clamp of the
minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
Starting the engine
1.Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.
2.Start the engine on the other vehicle in the
usual way.
If the first start attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the above connecting sequence.
If necessary, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
