Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
center replaces this combined filter as a stan-
dard part of your scheduled maintenance.
You can select a display of more detailed infor-
mation on the Control Display, refer to page75.
Parked car ventilation*
The concept
The parked car ventilation blows air into the
passenger compartment to lower interior tem-
peratures.
It is ready to use in the parked-car mode at any
outside temperature.
You can set two different times for the system
to start. The parked car ventilation can also be
switched on and off directly. It remains
switched on for 30 minutes.
Since the system uses a substantial amount of
electrical current, you should refrain from acti-
vating it twice in succession without allowing
the battery to be recharged in normal operation
between use.The air emerges through the upper body region
vent outlets in the instrument panel. These vent
outlets must be open for the system to operate.
The parked car ventilation is operated via iDrive.
Switching on and off directly
iDrive, for principle details, refer to page16.
1.Open the start menu.
2.Move the controller to the left to open
"Climate".
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 display of the automatic
climate control flashes.

What to do if …
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. Select a
destination that is as close as possible to
the original.
>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. Select a destination
that is as close as possible to the original.>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

Telephoning
The concept
Your BMW is equipped with a full mobile phone
preparation package. After logging on a suitable
mobile phone on the vehicle once, you can
operate the mobile phone via iDrive, with the
buttons on the steering wheel and by voice.
A mobile phone that has been logged on once is
automatically detected again with the engine
running or the ignition switched on as soon as
it is in the vehicle interior. The logon data of up
to four mobile phones can be stored simulta-
neously. If several mobile phones are detected
simultaneously, the respective last mobile
phone logged on can be operated via the vehi-
cle.
Using a phone in your vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a mobile phone
cradle, enables the battery to be charged and
the mobile phone to be connected to the exter-
nal antenna of your vehicle. This ensures
improved network reception and a consistent
voice reproduction quality. Ask your BMW cen-
ter which mobile phones snap-in adapters are
offered for.
BMW discourages the use of mobile
phones or other mobile communications
devices 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.<
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
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
Ask your BMW center which mobile phones
with a Bluetooth interface are supported by the
mobile phone preparation package or which
mobile phones snap-in adapters are available
for. These mobile phones support the functions
described in this Owner's Manual with a certain
software version. Malfunctions can occur with
other mobile phones.
Care instructions
You can find what you need to know about car-
ing for your mobile phone in the separate Caring
for your vehicle brochure and in the mobile
phone owner's manual.
Operating options
You can operate the mobile phone* using:
>The steering wheel, refer to page11
>iDrive, refer to page16
>Voice commands, refer to page174

When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page88.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as quickly as
possible.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page212.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
restrain the battery to prevent it from tipping
over during transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings are also lost
and must be updated:
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page45.
>Time and Date
The values must be updated, refer to
page80.
>Radio
Stations must be stored again if necessary,
refer to page150.
