Report of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.
If the vehicle is not, as provided at the
factory, equipped with run-flat tires,
refer to page172, stop driving. Continued
driving after a flat tire can result in serious
accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In case of a complete loss of the tire inflation
pressure or obvious tire damage, you can
estimate the possible driving distance for
continued driving base on the following ref-
erence values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tance and altered natural steering charac-
teristics.
If unusual vibrations occur while the vehicle
is being driven, this can indicate final failure
of the damaged tire. Reduce speed and stop as soon as possible. Do not continue
driving. Contact your BMW center.<
Malfunction
The warning lamp lights up in yellow. A
message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
A t l o w s p e e d , e . g . i n a t o w n o r w h e n p a r k i n g , t h e
steering angle of the wheels is reinforced, i.e.
the steering becomes very direct.
In the higher speed range, on the other hand,
the steering angle is reduced more and more.
This improves the handling capability of your
BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page82.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speed, larger steering wheel move-
ments are required, while the vehicle reacts
more sensitively to steering wheel movements
in the higher road-speed range. Have the sys-
tem checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.

A congenial climate
96 it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Residual heat mode
Press the button when the motor is
switched off and warm.
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. when stopped at a school to pick
up a child.
You can adjust the automatic climate control
settings as of ignition key position 1.
Provided that the engine has warmed to its nor-
mal operating temperature and the battery is
charged, you can use this function for up to
15 minutes after switching off the ignition. The
LED in the button lights up to confirm compli-
ance with both of these conditions.
Switching off automatic climate control
The air volume, the heater and the
cooling function are all switched
off.
You can restart the automatic cli-
mate control by pressing any of its buttons
except the REST button.
Settings using Control Center
Ignition key:
>In vehicles with separate drives for audio
CDs and navigation DVDs, ignition key in
position 2.
>In vehicles with one drive for audio CDs,
ignition key in position 1.
Control Center, for principle details, refer to
page16.1.Press the button.
This opens the start menu.
2.Move the controller to the left to open "Cli-
mate".

What to do if …
What to do if …
>a navigation DVD is inserted, but the
request to insert the DVD is displayed on
the Control Display?
The navigation DVD may not be the right
DVD for the navigation system. The DVD is
labeled accordingly.
>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 owing
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 under a clear sky.
>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 etc., then start
the destination guidance.>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 then
takes up to 10 minutes before the system is
once again operational.

Towing and tow-starting
Always observe all applicable towing laws
and regulations.<
Never allow passengers to ride in a towed
vehicle for any reason.<
Use tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page180, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
To avoid damage to the tow fitting and the
vehicle, observe the following: only use
the tow fitting that comes with the vehicle and
screw it in as far as possible. Use the tow fitting
for towing only on roads. Avoid lateral strains on
the tow fitting, e.g. do not the lift vehicle by the
tow fitting.<
Access to screw thread
Rectangular cover in bumper:
Press the arrow symbol of the cover.

Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering wheel
could lock and it would be impossible to steer
the vehicle. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering. Active steering is
deactivated and larger steering wheel move-
ments are required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, as otherwise the automatic
transmission may be damaged.<
Vehicles with SMG Sequential manual
transmission
With the ignition switched on, engage selector-
lever position N, then switch off the ignition.
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be strictly limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fitting only.
Otherwise to other vehicle parts could
result.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fitting only. Oth-
erwise damage to other vehicle parts could
result.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or body
and chassis parts, as otherwise damage
may result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
