Malfunction
The warning lamp lights up. PDC is
malfunctioning. Have the system
checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to op erate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 1 ft/30 cm.
Manual operation
The LED above the button also flashes.
System limitations
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind sp ot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with traile r towbars and hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e.g. curbs,
can disappear again from the detection area of
the sensors before or af ter a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Therefore, always drive
cautiously; otherwise, there is a risk of personal
injury or property damage.
Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage. <
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page 134.
Electronic brake-force distribution
EBV
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressu re on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical lim its by reducing engine
output and through braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains th e responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taki ng risks, as this could
result in an accident. <

Tire Pressure Monitor TPM
The concept
Check the inflation pressure
in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was co rrect; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
> When a wheel without TPM electronics is
installed.
> Interference with TPM by other systems or
devices with the same transmission fre-
quency.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
For operating principle refer to page 82.
1. Start the engine, but do not start driving.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Tire Pressure Monitor. The following dis-
play appears:
4. Press button 2 for approx. 5 seconds, until
the small warning lamp lights up in yellow
and the following appears in the display:
5. Start driving.
After several minutes of driving time, the
adjusted inflation pressures will be adopted as
nominal values. The resetting process is com-
pleted automatically as you drive. The indicator
lamp goes out after the system reset is com-
pleted.

ControlsTechnology for driving comfort and safety
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. In addition, a signal sounds.
> There is a flat tire or substantial loss of tire
pressure in the indicated wheel.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressure s initialized last.
Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers. If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
When driving with a damaged tire:
1. Avoid sudden braking and steering maneu-
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure is correct in all four
tires, then the Tire Pressure Monitor may
not have been reset. The system must then
be reset.
Possible driving distance with complete loss of
tire inflation pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving. With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics ch
ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously an d do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change , e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change. <
Vibrations or loud noises while driving can
indicate complete fa ilure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <

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.

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.

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.

Diagnosis OBD
On the drive r's side is a n OBD so cket f or check-
ing components relevant to the composition of
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have
the car checked as soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under ce rtain conditions. This
indicates excessive misfiring in the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
The warning lamp lights up if the fuel
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the fuel cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extr act form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.
