Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight 
parking spaces. Acoustic signals and a visual 
indicator
 warn you of the presence of an object 
behind your vehicle. Four ultrasonic sensors in 
the bumper measure the distance.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not 
sound until an object is approx. 2 ft/60 cm from 
the corner sensors, or approx. 5 ft/1.50 m from 
the center sensors.
PDC is a parking aid that can indicate 
objects when they are approached 
slowly, as is usually the case when parking. 
Avoid approaching an object at high speed; oth-
erwise, physical circumstances may lead to the 
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched 
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the 
automatic transmission selector lever to 
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above 
approx. 20 mph/30 km/h, the system switches 
off and the LED goes out.
Signal tones
When nearing an object, its position is indicated 
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases, 
the intervals between the tones become 
shorter. If the distance to the nearest object 
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx. 
3seconds:>If you stop in front of an object that has been 
detected by only one of the corner sensors
>If you are driving parallel to a wall
Malfunction
The indicator lamp in the instrument 
cluster comes on. PDC is malfunc-
tioning. A message appears on the 
Control Display. 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 operate 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.
PDC with visual warning
The approach of the vehicle to an object is 
shown on the Control Display. Objects that are 
farther away are displayed on the Control Dis-
play before a signal tone sounds. The display 
appears on the Control Display as soon as PDC 
is activated.
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 spot 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 trailer 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 after a continuous tone 
sounds. Higher, protruding objects, e.g. ledges, 
cannot be detected. Loud sound sources out-
side or inside the car can drown out the PDC 
signal. Therefore, always drive cautiously; oth-
erwise, there is a risk of personal injury or prop-
erty damage.<

Indication of a flat tire
The warning lamps come on in yellow 
and red. A message appears on the 
Control Display. In addition, a signal 
sounds. There is a flat tire or substan-
tial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of 
50 mph/80 km/h.
If the car is not equipped with run-flat 
tires, refer to page196, the standard 
equipment by design, do not continue driv-
ing. A severe accident could result if you 
continue driving after a tire puncture.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor 
might not have been initialized. The system 
must then be initialized.<
3.In the event of complete tire pressure loss, 
0 psi/0 kPa, you can estimate the distance for which you can continue driving on the 
basis of the following guidelines:
>With a light load: 
1 to 2 persons without luggage: 
approx. 155 miles/250 km
>With a medium load: 
2 persons, cargo area full, or 4 persons 
without luggage: 
approx. 90 miles/150 km
>With a full load: 
4 persons, cargo area full: 
approx. 30 miles/50 km
Drive cautiously and do not exceed a 
speed of 50 mph/80 km/h; otherwise, 
there is a risk of an accident. In the event of 
pressure loss, vehicle handling changes. This 
includes reduced tracking stability in braking, 
extended braking distance and altered natural 
steering characteristics.
If unusual vibration or loud noises occur during 
the journey, this may be an indication that the 
damaged tire has finally failed. Reduce your 
speed and pull over as soon as possible at a 
suitable location. Otherwise, parts of the tire 
could come loose, resulting in an accident. Do 
not continue driving. Instead, contact your 
BMW center.<
Status display

The tires are shown in gray and "Resetting 
TPM..." is displayed.
After driving a few minutes, the set inflation 
pressures in the tires are accepted as the target 
values to be monitored. The system reset is 
completed during your drive, and can be inter-
rupted at any time. When the trip is resumed, 
the reset is continued automatically. On the 
Control Display, the wheels are shown in green 
and "Status: TPM active" is displayed again.
If a flat tire is detected while the system is 
resetting and determining the inflation 
pressures, all wheels on the Control Display are 
displayed in yellow. The message "Low tire!" is 
shown.<
Message for low tire inflation pressure
The warning lamps come on in yellow 
and red. A message appears on the 
Control Display. In addition, a signal 
sounds. There is a flat tire or substan-
tial loss of tire pressure.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of 
50 mph/80 km/h.
If the car is not equipped with run-flat 
tires, refer to page196, the standard 
equipment by design, do not continue driv-
ing. Otherwise, a severe accident could 
result after a tire puncture if you continue 
driving.<
2.In the event of complete pressure loss, 
0 psi/0 kPa, you can estimate the possible 
distance for continued driving on the basis 
of the following guidelines:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo area full, or 4 persons without luggage:
approx. 95 miles/150 km
>With a full load:
4 persons, cargo area full:
approx. 30 miles/50 km
Drive cautiously and do not exceed a 
speed of 50 mph/80 km/h. In the event of 
pressure loss, vehicle handling changes. This 
includes reduced tracking stability in braking, 
extended braking distance and altered natural

Declaration according to NHTSA/
FMVSS 138
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 inflation 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 pressure 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 
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the 
low tire pressure telltale illuminates, you should 
stop and check your tires as soon as possible, 
and inflate them to the proper pressure. Driving 
on a significantly underinflated tire causes the 
tire to overheat and can 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 pressure, even if underin-flation has not reached the level at which the 
TPMS low tire pressure telltale illuminates.
The TPMS malfunction indicator 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, including 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 depending on the speed at 
which you are driving.
When you are driving in the low road speed 
range, e.g. in a town or when parking, the steer-
ing 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 improves 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 simultaneously deactivated 
when DSC is switched off, refer to page76.

Malfunction
The warning lamps come on. Active 
steering is malfunctioning or is tem-
porarily deactivated. At low speeds, 
greater steering wheel movements 
are required, whereas at higher speeds the 
vehicle reacts more sensitively to steering 
wheel movements. The stability-enhancing 
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature 
is deactivated. Initialization 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 text mes-
sage appears. Have the system checked.
Servotronic*
The concept
The Servotronic varies the steering force 
required to turn the wheels 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.
This system functions automatically.
Malfunctions
Malfunctions are displayed via Check Control, 
refer to page71.

Airbags
The following airbags are located under the 
marked covers:
1Front airbags
2Coupe: head airbags
3Side airbags in the seat backrests
4Convertible: knee airbags
Protective action
Observe the adjustment instructions on 
page43 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and 
front passenger by responding to frontal 
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the 
head and side airbags help provide protection in 
the event of side impact. The relevant side air-
bag supports the side upper body area. The 
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in 
minor accidents or rear-end collisions.
Do not apply adhesive materials to the 
cover panels of the airbags, cover them or 
modify them in any other way.
Keep the dashboard and window on the front 
passenger side clear, i.e., do not cover with 
adhesive labels or coverings, and do not attach 
holders such as for navigation instruments and 
mobile phones.
Do not attach seat covers, cushions or other 
objects not specifically approved for seats with 
integral side airbags to the front seats. Do not 
hang items of clothing such as coats or jackets 
over the backrests. Do not attempt to remove the airbag retention system from the vehicle. Do 
not modify the individual components of the 
system or its wiring in any way. This includes 
the upholstered covers on the steering wheel, 
instrument panel, seats and roof posts, as well 
as the sides of the roof lining. Do not attempt to 
remove or dismantle the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered, 
because there is a danger of burns.
In the event of malfunctions, deactivation or 
triggering of the airbag restraint system, have 
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center 
or a workshop that works according to repair 
procedures of BMW with correspondingly 
trained personnel and that has the required 
explosives licenses. Unprofessional attempts to 
work on the system could lead to failure in an 
emergency or to undesired airbag activation, 
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
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 passenger 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.< 
Page 86 of 250

Technology for driving comfort and safety
84 Before transporting a child on the front 
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, refer to page52.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indicator lamp for the front 
passenger airbags comes on. In such cases, the 
passenger should change his or her sitting 
position so that the front 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 lights up when a child in 
a specially designated child restraint sys-
tem is detected, as intended, on the seat.
The front and side airbags for the front pas-
senger are not activated.
Most child seats are detected by the 
system, especially child seats 
required by the NHTSA at the time of vehi-cle production. After mounting a child seat, 
ensure that the indicator lamp for the front 
passenger airbag is lit. It indicates that the 
child seat has been detected and that the 
front passenger airbags are deactivated.<
>The indicator lamp does not come on when, 
for example, 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 come on if the 
seat is empty.
The front and side airbags for the front pas-
senger are not activated.
Operational readiness of airbag system
As of radio readiness, refer to page55, the 
warning lamp comes on briefly 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 sufficiently severe acci-
dent occurs.<
Convertible: rollover 
protection system
The rollover protection system is activated 
automatically in the event of an accident, a crit-
