Do not continue driving. Contact your BMW
center.<
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four tires as you
drive. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly in relation to the pressure in another
tire.
The check of the tire inflation pressure is
based on monitoring the relative speeds
of the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirement
To ensure reliable operation, the system
should have been initialized with the cor-
rect tire inflation pressure.
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a
natural, even pressure drop in all four
tires.<
In the following situations, the system
could be delayed or malfunction:
>When you are driving on snow-covered
or slippery road surfaces
>In the case of performance-oriented
driving: 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
>If the Flat Tire Monitor was not initial-
ized after the last inflation pressure cor-
rection, false alarms indicating a flat tire
that is not present are possible or pres-
sure loss might not be detected.
Initializing 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.Start the engine, but do not drive off
2.Open the menu
3.Select "Vehicle settings" and press the
controller
4.Select "FTM" and press the controller
5.Select "Set tire pressure" and press the
controller
6.Select "Yes" and press the controller
7.Drive off.
The message "Initializing" is displayed.
It takes a few minutes before the Flat Tire
Monitor can detect and report a flat tire and
"Status: Active" is displayed.
If a flat tire is detected during initialization,
a message appears on the Control Display.
When driving with snow chains, do
not initialize the system.<

Report of a flat tire
The warning lamp lights up in red
and a message appears on the
Control Display. 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
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
side walls of the run-flat tires,
inflation pressure loss can not usually
be recognized from the outside, refer to
Run-flat tires on page 168.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page 168.
Malfunction
The warning lamp lights up yellow
and a message appears on the
Control Display. The Flat Tire Moni-
tor has a malfunction or has failed. Have
the system checked as soon as possible.
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 of the wheels is reinforced,
i.e. the steering becomes very direct.
In the higher speed range, on the other
hand, the steering angle of the wheels 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
targeted changes to the steering angle pro-
vided by the driver and thus stabilize the
vehicle before the driver intervenes.
Malfunction
The fixed warning lamp lights up.
The active steering is no longer
operational. In the low speed range,
greater steering wheel movement is neces-
sary. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply
interruption, the system must be activated
with initialization.
Initializing system
1.Start the engine
2.With the vehicle stationary, turn the
steering wheel from the straight-ahead
position to the left as far as it will go and
then back to the straight-ahead position
3.Switch off the engine.
When you start the engine again, all the
functions of the active steering are avail-
able once again.
Brake Force Display
The two-stage brake lamps light up in two
stages depending on how strongly you
brake.
>Normal braking:
The brake lamps and the third brake
lamp go on
>Heavy braking and braking with ABS:
In addition, the light area of the rear
brake lamps is enlarged, refer to illus-
tration.

Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front pas-
senger
2Coupe: head airbags
3Front side airbags
4Knee airbag for front passenger
5Knee airbag for driver
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone can-
not provide adequate restraint. When
needed, the head and side airbags help
provide protection in the event of a side
impact. The side airbags help restrain the
side of the occupant's upper torso, and the
head airbags help support the head while
also helping provide protection against any
objects penetrating into the passenger
compartment.
The airbags are deliberately not triggered
in every impact situation, e.g. less severe
accidents, certain rollover conditions, or
rear-end collisions.
For information on the correct sitting posi-
tion, refer to page 42.
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild hearing loss in
extremely sensitive individuals. This effect
is usually only temporary.Do not apply adhesive materials to
the cover panels of the airbags, cover
them or modify them in any other way.
Do not attempt to remove the airbag reten-
tion system from the vehicle. Never modify
or tamper with either the wiring or the indi-
vidual components in the airbag system.
This category includes the upholstery in the
center of the steering wheel, on the instru-
ment panel, the side trim panels on the
doors and on the Coupe the roof pillars
along with the sides of the headliner.
Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been trig-
gered, because there is a danger of burns.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem is triggered in response to an accident,
you should always entrust all inspection,
repair and dismantling operations to your
BMW center. Unprofessional attempts to
service the system could lead to failure in
an emergency or undesired airbag activa-
tion, either of which could result in personal
injury.<
Airbag warning information is also provided
on the sun visors.

Airbag system operational
The airbag warning 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 warning lamp goes out after a few sec-
onds.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem not responding in the expected man-
ner to an impact occurring within its normal
response range.<
There is a malfunction in the airbag
system when:
>The warning lamp does not light up as
of ignition key position 1
>The warning lamp remains on continu-
ously
>The warning lamp lights up while the
vehicle is being driven.

Rollover protection system
The rollover protection system is automati-
cally activated in the event of an accident
or a critical driving situation, extreme incli-
nation on the longitudinal or transverse
axis, or loss of ground contact. The rollover
bars located behind the rear head
restraints move out within fractions of a
second.As a supplement to the rollover bar inte-
grated in the windshield frame, the rollover
protection system ensures that all vehicle
occupants have the necessary headroom.
Always keep the path of movement of
the rollover protection system clear.
In less severe accidents, you are protected
by the fastened safety belt and, depending
on the severity of the accident, the belt ten-
sioner and the multistage airbag restraint
system.<
Lowering
If the protection function was not required
after automatic activation, the rollover pro-
tection system can be lowered again.
No tools are necessary for this purpose.
1.Press the release backwards and hold
in that position
2.Press the rollover bar halfway down
from above
3.Let go of the release
4.Press the rollover bar down until it
snaps into place
5.Use the same procedure for the second
rollover bar.
Have the rollover protection system
checked after unexpected triggering.

Never move the convertible top when
the rollover protection system is
raised.
No changes of any nature may be made to
the individual components of the rollover
protection system and wiring.
Work on the rollover protection system may
only be performed at a BMW center.
Unprofessional attempts to service the sys-
tem can lead to failure or malfunction.
For a system check and to ensure long-
term functioning, you must comply with the
maintenance intervals of the service
requirement display.<

you that the lamps have not yet been
switched off. At the same time a message
appears on the Control Display.
Daytime driving lamps*
If you wish, you can leave the light switch in
the low-beam position.
Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
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.
The low beams remain on indepen-
dent of the ambient lighting condi-
tions when you switch on the fog lamps.
With the daytime driving lamps activated,
the low beams are always switched on in

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 better illumina-
tion of the road surface. Depending on the
