Ventilation in the rear
1Use the knurled wheel to smoothly open
and close the air vents
2Use the knurled wheel to adjust the temper-
ature:
>Turn toward blue: colder
>Turn toward red: warmer
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.
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
iDrive, for operating principle refer to page16.
1.Press the button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".

the controller.
5.Select "Parked car ventilation" and press
the controller.
The parked car ventilation is switched on.
The symbol on the automatic climate control
display flashes.

mobile phone base plate refer to the separate
Owner's Manual.
Opening
Press the button, see arrow.
Ventilated storage compartment
The storage compartment in the center armrest
can be ventilated: slide the switch backwards.
The temperature is controlled via the knurled
wheel for adjusting the temperature of air venti-
lating the rear of the passenger compartment,
refer to page100.
Connection for external audio device
You can connect an external audio device such
as a CD or MP3 player and play audio tracks
over the car's loudspeaker system:
>AUX-In port, refer to page171
>USB-audio interface
*, refer to page172
Storage compartments inside
the vehicle
Depending on your vehicle's equipment, you

* on the front-seat backrests.
Clothes hooks
There are clothes hooks on the grab handles in
the rear passenger compartment.
Items of clothing hung from the hooks
must not obstruct the driver's view. Do
not hang heavy objects from the hooks, other-
wise they could endanger the car's occupants,
e.g. in case of heavy braking or sudden swerv-
ing.<

Practical interior accessories
110 On uphill gradients, release the drawer with
caution, otherwise it could slide out on its own
and cause injury.
Do not exceed a maximum load of 11 lbs/5 kg
for the drawer, otherwise damage could
result.<
Removing the drawer
1.Push the drawer all the way in.
2.Turn the catches on the left and right all the
way out.
3.Remove the drawer by pulling it down and
backwards.
Reinserting the drawer
1.Hook the guides of the drawer into the front
of the yellow guide aids on the bottom of the
cargo bay.
2.Insert the catches into the mounts on the
bottom of the cargo bay.
3.Turn the catches on the left and right all the
way in.
Folding up the floor panel
Do not exceed the maximum permissible
load of 55 lbs/25 kg for the storage com-
partment under the floor panel, otherwise dam-
age could result.<
Press the floor panel against the ceiling of the
cargo bay; a locking device holds the floor panel
in place. To detach the floor panel, pull it out of
the locking device.
With drawer:Take the retaining strap on the right-hand side
of the drawer out of the bracket and use it to fix
the floor panel in place.
Lashing eyes
You will find lashing eyelets in the cargo bay for
securing luggage items with nets or tensioning
straps, refer to page117.
Ski bag*
The ski bag is designed for safe, clean transport
of up to 4 pairs of standard skis or up to
2snowboards.
With the ski bag you can stow skis with a length
of up to 6 ft 10 in/2.10 m. When skis of 6 ft 10 in/
2.10 m length are loaded, the overall capacity of
the ski bag is reduced due to its tapered design.
Loading
1.Fold down the center armrest.
2.Press the button, reach into the recess and
fold down the cover.
3.Open the Velcro fastener, spread the ski
bag between the front seats and insert the
skis or snowboards.
The zip fastener makes objects in the ski
bag easier to reach.

Things to remember when driving
116 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 page119.
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.

Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Securing cargo
>Secure smaller and lighter items using
retaining straps, a cargo bay net
* or draw
straps
*.>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes are
provided for attaching the cargo straps.
Two are located on the cargo bay
sidewalls1, two more are on the rear cargo
bay panel2.
Please comply with the information sup-
plied with the cargo straps.
Position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page240, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.
Only attach the cargo straps using the lashing
eyes shown in the illustration. Do not secure
cargo with the anchors for tether straps, refer to
page52, otherwise these could be damaged.<
Roof-mounted luggage rack*
A luggage rack mounted on the roof
changes vehicle aerodynamics and han-
dling. Exercise restraint when driving with a
roof-mounted luggage rack to avoid the risk of
an accident.<
A special rack system is available as an option
