Tire Pressure Monitoring Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire infl ation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pres sure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
t e l l t a l e w h e n o n e o r m o r e o f y o u r t i r e s a r e s i g n i f -
icantly underinflated. Accordingly, when the
low tire pressure telltal e illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underi nflated tire causes the
tire to overheat and ca n lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pr essure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
The TPMS malfunction in dicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue upon subsequent vehicle 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 malfunctions 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
telltale 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 function properly.Active steering
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depe nding on the speed at
which you are driving.
When you are driving in the low speed range,
e.g. in a town or when parking, the steering
angle is increased, i.e. steering becomes very
direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This im proves the handling 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 stabilizing
intervention is simult aneously deactivated
when DSC is switched off, refer to page 91.

ControlsTechnology for driving comfort and safety
Malfunction
The warning lamps light up. Active
steering is malfunctioning or is tem-
porarily deactivate d. At low speeds,
greater steering wheel movements
are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. Th e stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deacti vated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initializ ation may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
If there is a defect, a corresponding message
appears. Have the system checked.
Servotronic
The concept
The Servotronic varies the steering force
required to turn the whee ls relative to the vehi-
cle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
Malfunction
The warning lamp lights up. Ser-
votronic is malfunctioning or has
failed. Steering response will be dif-
ferent. You can continue your journey, but mod-
erate your speed and exercise due caution.
Have the system checked as soon as possible.

Automatic deactivation of the front
passenger airbags
An analysis of the impression in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front pass enger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or
activated, refer to Status of front passenger air-
bags below. <
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling inst ructions under Trans-
porting children safely, refer to page 53.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indi cator lamp for the front
passenger airbags lights up. In such cases, the
passenger should change his or her sitting
position so that the fr ont passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, transport the rele-
vant passenger on a rear seat. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the front passenger seat unless
they are specifically recommended by BMW.
Do not place any items under the seat which
could press against the seat from below. Other-
wise, a correct analysis of the seat cushion is
not ensured. <
Status of front passenger airbags
The indicator lamp for the front passenger air-
bags shows the functional status of the front
passenger front and side airbags in accordance
with whether and how the front passenger seat
is occupied. The indicator lamp shows whether
the front passenger airbags are activated or
deactivated.
>The indicator lamp light s up when a child in
a specially designated child restraint sys-
tem is detected, as in tended, on the seat.
The front and side airbags for the front pas-
senger are not activated.
Most child seats are detected by the
system, This partic ularly applies to
child seats that were required by NHTSA at
the time of manufacture of the vehicle. After
mounting a child seat, ensure that the indi-
cator lamp for the fron t passenger airbag is
lit. It indicates that th e child seat has been
detected and that the front passenger air-
bags are deactivated. <
> The indicator lamp does not light up as long
as a person of sufficient size and in a correct
sitting position is detected on the seat.
The front and side airbags for the front pas-
senger are activated.
> The indicator lamp does not light up if the
seat is empty.
The front and side airbags for the front pas-
senger are not activated.

Operational readine
ss of airbag system
As of radio readiness, refer to page 57, the
warning lamp lights up br iefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
> Warning lamp does not light up at radio
readiness or beyond.
> Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a su fficiently severe acci-
dent occurs. <
Convertible: rollover
protection system
The rollover protection system is activated
automatically in the event of an accident, a crit-
ical driving situation, an extreme tilt in the car's
longitudinal axis or upon loss of ground contact.
The protection bars behind the rear head
restraints deploy within fractions of a second.
As a supplementary system to the reinforced
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is
maintained for all vehicle occupants. Always keep the area of movement of the
rollover protection system clear.
In minor accidents, yo u are protected by the
fastened safety belt and, depending on acci-
dent severity, by the sa fety belt tensioner and
multi-phase airbag retention system. <
Resetting
If the rollover protection system was not
impacted after being automatically activated, it
can be reset by lowering the protection bars to
their original positions. This does not require
tools.
1. Push the locking lever to one side and hold
it there.
2. Push the protection bar halfway down from
above.
3. Release the locking lever.
4. Push the protection bar down until it snaps
into place.
5. Repeat the procedure for the other protec-
tion bar.
Have the rollover protection system checked
after an unexpected activation.

General information
When the driver's door is opened with ignition
switched off, then the ex terior lighting is auto-
matically switched off if the light switch is in
position 0, 2 , or 3.
Parking lamps
In switch position 1, the front, rear and side
vehicle lighting is switch ed on. You can use the
parking lamps for parking.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enou gh power to start the
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps,
refer to page 105.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
When the switch is in position 3, the low beams
are switched on and o ff automatically depend-
ing on ambient lighting conditions, e.g. in a tun-
nel, in twilight, or if there is precipitation. The
Adaptive Light Control is active. The LED next
to the symbol is illuminated when the low
beams are on. You can also activate the daytime
running lights, refer to page 104. In the situa-
tions described above, the lamps then automat-
ically switch fr om daytime running lights to low
beams.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps. <
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determin ing when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or ha zy weather. To avoid
safety risks, you should always switch on the
low-beam headlamps ma nually under these
conditions. <

Adaptive Light Control
The concept
Adaptive Light Control is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves at speeds up to 40 mph/70 km/h,
e.g. on mountainous roads or when turning, an
additional, corner-illuminating lamp is switched
on that lights up the inside area of the curve.
Activating Adaptive Light Control
With the ignition switch ed on, turn the light
switch to position 3, refer to page 103.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
Standstill function: to avoid blinding oncoming
traffic, the Adaptive Light Control directs light
toward the front passenger side when the vehi-
cle is at a standstill. When you are reversing, only the corner-illumi-
nating lamps are switched on and active on
both sides.
Malfunction
The warning lamp lights up. The
Adaptive Light Control is malfunc-
tioning or failed. Have the system
checked as soon as possible.

down beyond the pressu re point for a longer
period, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enou gh power to start the
engine. <

High-beam Assistant
The concept
This system automatica lly switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handle s this task for you and
gives you the benefit of the best possible view.
You can intervene at any time and switch the
high beams on and off as usual.
Activating the system
1. Turn the light switch to position 3, refer to
page 103.
2. With the low beams switched on, briefly
push the turn signal/high beam lever in the
direction of the high beam.
The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-
cally switches from hi gh beams to low beams
and vice versa in response to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.
Switching the high beams on and off
manually
Whenever you wish, or when the situation
requires, you can intervene:
> If the High-beam Assistant switches on the
high beams, but you wo uld like to drive with
the low beams, simply switch off the high
beams using the turn signal/high beam
lever. This deactivates the High-beam
Assistant.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again. >
If the High-beam Assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deactivates the system and
the high beams need to be switched off
manually, if necessary.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.
> Use the headlamp flashe r as usual with the
low beams switched on.
System limitations
The High-beam Assistant cannot serve
as a substitute for the driver's personal
judgment of when to use the high beams.
Therefore, manually switch off the high beams
in situations where this is required to avoid a
safety risk. <
The system is not fully fu nctional in situations
such as the following, and driver intervention
may be necessary:
> In very unfa vorable weather conditions,
such as fog or heavy precipitation
> In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings
> In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways
> In poorly lit towns and cities and in the pres-
ence of highly reflective signs
> At low speeds
> When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
> If the sensor is dirty. Clean the sensor on
the front of the interior rearview mirror using
a cloth moistened with a small amount of
glass cleaner.
