natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>If you are using a sports driving style:
slip on the drive wheels, high lateral
acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted
>When you are driving with the compact
wheel, the Flat Tire Monitor is unable to
function.
Initializing the system
Perform the initialization immediately
after correcting the inflation pressure,
after changing a tire or changing a wheel or
all wheels. A drive is necessary for this pur-
pose.<
Control Center, for principle details, refer to
page 16:
1.Before beginning driving, start the
engine, but do not drive off
2.Open the menu
3.Select "Vehicle settings" and press the

a message appears on the Control Display.
When driving with snow chains or
with the compact wheel, do not initial-
ize the system.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in red and a simulta-
neous message appears on the
Control Display. In addition, an acoustic
signal sounds.
Please note any supplementary information
that appears on the Control Display. You
can find more information on the Check
Control starting on page 68.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and

2.Identify damaged tire
If identification is not possible,
contact your BMW center.<
3.Replace the damaged wheel, refer to
Changing a tire on page 187.
Vehicles with run-flat tires:
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
edges of the run-flat tires, inflation
pressure loss can not usually be recog-
nized from the outside, refer to Run-flat
tires on page 175.<
2.To continue driving, comply with the
instructions for driving with damaged

Indicator lamp
The symbol in the instrument clus-
ter lights up yellow and a message
appears on the Control Display.
Please contact your BMW center.
Please note any supplementary information
that appears on the Control Display.
Active steering*
The concept
The active steering is a system that actively
varies the steering angle of the front wheels
in relation to the steering wheel move-
ments.
When you are driving in the low road speed
range, e.g. in a town or when parking, the
steering angle is reinforced, i.e. the steer-
ing becomes very direct and significantly
improves the handling capability of your
BMW.
In the higher road speed range, on the
other hand, the steering angle is reduced,
also optimizing the handling capability.
In critical situations, the system can make
targeted changes to the steering angle pro-
vided by the driver and thus stabilize the
vehicle before the driver intervenes.
Indicator lamp
The indicator lamp lights up perma-
nently: malfunction in the system.
Please have the system inspected
at your BMW center.
Conventional steering efficiency remains
available without limitations.
Brake Force Display
The Brake Force Display indicates the
intensity with which you are applying your
brakes to drivers of following vehicles. The display consists of two stages:
>Normal braking:
The brake lamps in the tail assemblies
and the high-mount brake lamp on top
of the rear window light up during brak-
ing
>Heavy braking and braking with ABS:
The tail lamps also light up with the
same intensity as the standard brake
lamp units to enhance the warning
effect of the brake lamps.

Technology for comfort, convenience and safety
84 >When a child is seated in the child-
restraint system or with an empty seat,
the front and side airbags are automat-
ically deactivated on the passenger's
side
>When an adult is traveling in the front
seat, the front and side airbags remain
active on the passenger side.
Although not desired, it can occur in
the case of heavier children that the
front passenger airbags remain active or in
the case of very light adults or young per-
sons that the front passenger airbags are
deactivated.
The state of the front passenger airbags is
shown with the telltale lamp, refer to Indi-
cator lamps in the following. In this case
transport the corresponding persons on
the rear seat.
Except when persons to be transported, do
not increase the load on the front passen-
ger seat with additional items. Do not fit
seat covers, seat cushion padding, ball
mats or other items to the front passenger
seat unless they are specifically recom-
mended by BMW. Do not place any items
under the seat. Otherwise, the function of
the seat occupation detection could be
impaired.<
Indicator lamps
Operational readiness of airbag
system
The airbag indicator lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The indicator lamp goes out after a few
seconds.The telltale lamp above the interior rear-
view mirror indicates whether the front-
passenger airbag system is activated or
deactivated as of ignition key position 1.
The telltale lamp refers exclusively to
the front-passenger airbag system.<
>The telltale lamp goes out after a few
seconds.
The front passenger airbags are active,
e.g. when transporting an adult
>The telltale lamp lights up continuously.
The front passenger airbags are deacti-
vated, e.g. when transporting a child in
the child-restraint system or when the
seat is unoccupied.
For more information on the operating prin-
ciple of the front passenger airbag system
and seat occupation detection, refer to
Automatic deactivation of the front passen-
ger airbags.
Airbag system malfunction
A system malfunction could prevent
the system from responding in the
expected manner to an impact occurring
within its normal response range.
Please have the airbag system inspected
immediately at a BMW center.<
There is a fault in the airbag system
if the airbag indicator lamp in the
instrument cluster behaves as fol-
lows:
>Indicator lamp does not light up as of
ignition key position 1
>It remains on continuously
>Indicator lamp lights up while the vehi-
cle is being driven.

needed using the standard procedure
described under Parking lamps.
Automatic headlamp control*
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in a tunnel, at
dawn and dusk, and in rain and snow. The
LED next to the symbol is illuminated when
the low beams are on.

Lamps
88 Following automatic activation, the
vehicle's external lighting remains on
when you switch on the fog lamps.<
The automatic headlamp control can-
not serve as a substitute for your per-
sonal judgment in determining when the
lamps should be switched on in response
to ambient lighting conditions. For exam-
ple, the system cannot detect fog. To avoid
safety risks, you should always switch on
the lamps manually under these condi-
tions.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumi-
nation of the road surface. Depending on
the steering angle and other assumptions,
the light from the headlamp follows the
course of the road.

The figures on the display pro-
vide a general indication of inte-rior temperature. A pleasant adjustment is
727/226. When you start the vehicle, the
system ensures that the selected tempera-
ture is achieved as quickly as possible. It
then maintains this temperature, regard-
less of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and front side win-
dows.
Adjusting the air volume manually
You can adjust the air volume
by turning. You can reactivate
the automatic mode for the air
volume with the AUTO button.
Switching cooling function on and off
manually
The cooling function cools and
dehumidifies the incoming air
before also reheating it as
required, according to the temperature set-
ting. Depending on the weather, the wind-
shield may fog over briefly when the engine
is started.
The cooling function comes on automati-
cally when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
