Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
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:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
>TPM is being reset
>Temporary interference due to systems or
devices which use the same radio fre-
quency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
Resetting finishes during driving, which can be
interrupted at any time. When driving resumes,
resetting is continued automatically.

proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level
to trigger illumination of the TPMS low tire
pressure indicator.
The TPMS malfunction indicator is combined
with the low tire pressure indicator. When the
system detects a malfunction, the indicator will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction indicator after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to func-
tion properly.
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.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, 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 page87.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control
Display. The active steering is no
longer operational. At low speed, larger steering
wheel movements are required, while the vehi-
cle reacts more sensitively to steering wheel
movements in the higher road speed range.
The stability-promoting intervention can also
be deactivated. Proceed cautiously and drive
defensively. Have the system checked.

The front, knee and side airbags on the front
passenger side can be deactivated for teenag-
ers and adults in certain sitting positions; the
indicator lamp for the front passenger airbags
lights up when this occurs. In these cases,
change the sitting position so that the front pas-
senger airbags are activated and the indicator
lamp goes out. If the desired status cannot be
produced by changing the sitting position,
transport the corresponding person in the rear
seat.
Do not fit seat covers, seat cushion padding,
beaded mats or other items onto the front pas-
senger seat unless they are specifically recom-
mended by BMW. Do not place objects under
the seat which could press against the seat
from below. Otherwise, a correct evaluation of
the occupied seat surface cannot be ensured.<
Operating state of front passenger
airbags
The illustration here shows a possible arrange-
ment in the Coupe. With some vehicle equip-
ment packages or in the Convertible, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front,
knee and side airbags on the front passenger
side depending on whether the seat is occu-
pied. The indicator lamp shows whether the
front passenger airbags are activated or deacti-
vated.
>The indicator lamp lights up when a child in
a child restraint system intended for the
purpose is properly detected on the seat.
The front, knee and side airbags on the front
passenger side are deactivated.Most child seats are detected by the sys-
tem. Especially the child seats required
by the NHTSA at the time the vehicle is manu-
factured. After installing a child seat, make sure
that the indicator lamp for the front passenger
airbags lights up. This indicates that the child
seat has been detected and the front passenger
airbags are not activated.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front, knee and side airbags on the front
passenger side are activated.
>The indicator lamp does not light up when
the seat is empty.
But the front, knee and side airbags on the
front passenger side are still deactivated.
Operational readiness of airbag system
From radio readiness, refer to page58, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up as of radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction; otherwise,
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<

Convertible: rollover
protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal axis, or loss of ground contact. The
rollover bars located behind the rear head
restraints are deployed within fractions of a sec-
ond.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion 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 tensioner and
the multistage airbag restraint system.<
Lowering
If the rollover protection system experienced no
impact after automatic activation, then it can be
lowered again. No tools are necessary for this
purpose.
1.Press the release backward and hold in that
position.
2.Press the rollover protection unit halfway
down from above.
3.Let go of the release.4.Press the rollover protection unit down until
it snaps into place.
5.Use the same procedure for the second roll-
over protection unit.
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 protec-
tion system and wiring.
Work on the rollover protection system may
only be performed at a BMW center.
Unprofessional attempts to service the system
can lead to failure or malfunction.
For a system check and to ensure long-term
functioning, you must comply with the mainte-
nance intervals of the service requirements,
refer to page77.<
Head-Up Display*
The concept
With the Head-Up Display, important informa-
tion is projected into the driver's field of view,
e.g. navigation instructions. This enables you to
absorb this information without looking away
from the road.

Any improvement in detection depends on
many factors such as the object size and tem-
perature compared to the surroundings, or
other nearby objects, the visual recognition
skills of the driver, weather conditions, and
other factors.
Driving hints
With the system active, periodically but briefly,
glance at the thermal image on the Control Dis-
play to notice objects that could be people or
larger animals. The glance should be similar to
glancing at the rear view mirror. Do not stare at
the image for long periods while driving, as this
will remove attention from the road. If you notice
an object of interest ahead, be prepared to slow
down or stop, blow the horn, or take other
appropriate action.
System limits
The system is designed to supplement but not
replace forward vision through the windshield.
The driver is responsible for safe driving at
night. BMW Night Vision is not designed to be
used as a continuous viewing window for driv-
ing at night.
No system, no matter how sophisticated, can
operate without limitations. BMW Night Vision
operation is subject to physical and environ-
mental limitations that will reduce the ability of
the system to detect and display a clear thermal
image. Some of the situations in which these
limitations can occur are:
>on steep hilltops or depressions and in tight
curves
>in tunnels, as the contrast is inherently low
>when the camera lens is dirty>in dense fog, heavy rain or snowfall
>when displaying very hot objects such as
transformers, car exhausts etc.
>when the image briefly freezes during nor-
mal system adjustment.
BMW Night Vision's potential benefits
can be limited by the driving style of the
driver, the size and relative temperature of the
detected objects, dirt or contamination on the
camera lens, adverse weather like snow, rain or
fog, and other factors not mentioned here. It will
always be the driver's responsibility to drive at a
speed and in a manner that recognizes potential
hazards and adjust accordingly.
BMW Night Vision is not a substitute or replace-
ment for driver responsibility or for accommo-
dating the visibility conditions and the traffic sit-
uation. The forward view illuminated by the
headlamps must always be the basis for making
safe driving decisions, otherwise a safety risk
will result.<
Activating BMW Night Vision
1.Turn the light switch to position2 or3, refer
to page102.
2.With low beams switched on:
>Press the button. Depending on the
vehicle's equipment, the location of the
button may differ somewhat.
>Press one of the programmable buttons
on the steering wheel, refer to page55.
The image will be displayed on the Control Dis-
play after a few seconds. Depending on the last
mode selected, either the normal or full screen
image will be displayed.

age to the lens, do not use sharp or abrasive
instruments to clean ice, snow, or dirt off the
lens.
When the windshield is cleaned with the head-
lamps on, the camera lens area is automatically
sprayed as well. Refer to page64.
Leaving lane warning*
The concept
This system warns you from a speed of approx.
40 mph/70 km/h when the vehicle is leaving the
lane you are currently in on roads with lane limit
lines. You feel this due to a slight vibration of the
steering wheel.
The system does not warn you if you signal
before leaving the lane.
It is best to use the system on well-developed
roads and freeways.
Switching on/off
Press the button on the steering wheel.
>The two lines1 indicate that the system is
activated.
>The two arrows2 mean that the system has
detected one or two lane limit lines from a
speed of approx. 40 mph/70 km/h and
warns accordingly.
If you activate the system below a speed of
approx. 40 mph/70 km/h, a message will appear
stating that the system is not active until this
speed is reached.
A warning will be canceled:
>after approx. 3 seconds
>if you return to your lane>if you brake heavily
>if you signal
System limits
The leaving lane warning cannot serve as
a substitute for your personal judgment in
determining the course of the road.
If the system issues a warning, do not move the
steering wheel with unnecessary severity, as
otherwise you could loose control of the vehi-
cle.<
The function of the system may be limited in the
following example situations:
>in heavy fog, rain or snowfall
>with worn-away, poorly visible limit lines, or
lines that run together or apart or are
unclear, e.g. in road construction areas
>when limit lines are covered by snow, ice,
dirt or a great deal of water
>in tight curves or on narrow roads
>when limit lines are not white
>when limit lines are covered by objects
>when driving up close behind a vehicle driv-
ing ahead
>with bright counter light
>when the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror

Manually switching between high
beams and low beams
If you wish or the situation requires, you can
intervene at any time.
>If the high-beam assistant has switched on
the high beams, but you wish to use the low
beams, just switch on the low beams with
the turn signal lever. This deactivates the
high-beam assistant.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>If the high-beam assistant has switched on
the low beams, but you wish to use the high
beams, simply switch on the high beams as
usual. This deactivates the system and it is
up to you to switch back to low beams.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>When the low beams are on, use the head-
lamp flasher as usual.
System limits
The high-beam assistant is designed to
maximize the amount of time that high
beams can be safely used and to quickly switch
back to low beams when traffic approaches.
The system cannot completely replace driver
intervention when unusual conditions are
encountered. For this reason, switch to low
beams when circumstances so dictate. Failure
to do so can pose a safety risk.<
Below are a few examples of situations in which
the system may not react or may only function
to a limited degree, requiring personal interven-
tion:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation
>in sensing road users with poor inherent
illumination such as pedestrians, cyclists,
equestrians, horsedrawn vehicles, railroad
or shipping traffic close to the road, and at
deer crossings>in tight curves, on steep crests or dips, with
cross-traffic, or with partially hidden
oncoming traffic on divided highways
>in poorly illuminated areas and in the pres-
ence of highly reflective signs
>in the low speed range
>when the windshield is fogged up, dirty or
covered with stickers, decals etc. in the area
of the inside rearview mirror
>when the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth slightly moistened with glass
cleaner
Moreover, no system can operate without limi-
tations. High-beam assistant operation is sub-
ject to conditions that may reduce the system's
ability to recognize the difference between
actual vehicle head lamps or tail lamps and, for
example, highly reflective signs, markers, and
streetlights. To be on the safe side, the system
may periodically interpret these situations as
conditions that require low beams. Below are
some of the situations in which premature
switching to low beams can occur:
>approaching large and/or highly reflective
signs
>approaching certain lights, such as drive-
way lighting and porch lights
>approaching certain traffic signals
>approaching large reflective markers
In these situations, the system may interpret
the above conditions as a vehicle ahead requir-
ing a switch to low beams. When the conditions
return to normal, the system will reactivate the
high beams.
The high-beam assistant cannot replace the
driver's responsibility for complying with state
laws on high-beam switching or for adapting to
visibility and traffic conditions.
