Indication of a flat tire
The warning lamp lights up red. A mes-
sage 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 severe brak-
ing and steering maneuvers and do not 
exceed a speed of 50 mph/80 km/h.
Stop driving if the vehicle is no longer 
equipped with run-flat tires, as it was 
when it came from the factory, refer to 
page218. Continued driving after a flat tire 
can result in serious accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four 
tires is correct, the Flat Tire Monitor 
may 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 possible 
distance for continued driving on the basis 
of the following guide values:
>With a light load: 
1 to 2 persons without luggage: 
approx. 155 miles/250 km
>With a medium load: 
2 persons, cargo bay full, or 
4 persons without luggage: 
approx. 94 miles/150 km
>With a full load: 
4 persons, luggage compartment full: 
approx. 30 miles/50 km
Drive reservedly 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 dis-
tance and altered natural steering charac-
teristics.
If unusual vibrations or loud noises occur 
while the vehicle is being driven, this can 
indicate final failure of the damaged tire. 
Reduce speed and stop at a suitable loca-tion as soon as possible, otherwise pieces 
of the tire could become detached and 
cause an accident. Do not continue driving, 
but instead contact your BMW center.<
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the 
four mounted tires. The system reports when 
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat 
tire, the system must have been reset with the 
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not 
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after 
every tire or wheel change.<
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.

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 underinflated. 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 to trigger illumi-
nation of the TPMS low tire pressure telltale.
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 illuminated. This sequence will 
continue upon subsequent vehicle startups as 
long as the malfunction exists. When the mal-
function indicator lights up, 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
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 page89.
Malfunction
The warning lamp lights up yellow and 
a message is shown on the Control Dis-
play. Active steering is malfunctioning 
or is temporarily deactivated. At low speed, 
larger steering wheel movements are required, 
while the vehicle reacts more sensitively to 
steering wheel movements in the higher road 
speed range. The stability-promoting interven-
tion can also be deactivated. Proceed cau-
tiously and drive defensively. Have the system 
checked if the active steering is malfunctioning.

Protective action
To ensure that the safety systems con-
tinue to provide optimized protection, 
please observe the adjustment instructions on 
page49.<
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 knee air-
bag protects the legs from colliding with the 
cockpit.
The airbags are deliberately not triggered in 
every impact situation, e. g. less severe acci-
dents 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. Do not attempt to 
remove the airbag restraint system from the 
vehicle. Do not modify or tamper with either the 
wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the 
instrument 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 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 BMW 
repair procedures with correspondingly trained 
personnel and has the required explosives 
licenses. Otherwise unprofessional attempts to 
service the system could lead to failure in an 
emergency or undesired airbag triggering, 
either of which could result in personal injury.<
Warnings and information on the airbags is also 
provided on the sun visors.
Automatic deactivation of front 
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The system 
correspondingly activates or deactivates the 
front, knee and side airbags on the front pas-
senger side.
The current status of the front passenger 
airbag, i.e. deactivated or activated, is 
indicated by the indicator lamp over the interior 
rearview mirror, refer to Operating state of front 
passenger airbags in the following.<
Before transporting a child in the front 
passenger seat, read the safety informa-
tion and follow the instructions under Trans-
porting children safely, refer to page58.
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, 
ball mats or other items onto the front passen-
ger seat unless they are specifically recom-
mended by BMW. Do not lay 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's seats are detected by the 
system. Especially the child's seats 
required by the NHTSA at the time the vehicle is 
manufactured. After installing a child's seat, 
make sure that the indicator lamp for the front 
passenger airbags lights up. This indicates that 
the child's seat has been detected and the front 
passenger airbags are not activated.<
>The indicator lamp does not light up if, for 
example, the system detects a person of 
sufficient size seated correctly 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 page60, 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 from 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 minor accidents, you are protected by the 
fastened safety belt and, depending on acci-
dent severity, by the safety belt tensioner and 
multi-phase airbag retention system.<

Socket for OBD Onboard 
Diagnostics interface
Components which are decisive for the 
exhaust-gas composition can be checked via 
the OBD socket with a device.
This socket is located under a cover on the left 
side of the driver's footwell, directly under the

Exhaust-gas values
The warning lamp lights up. The 
exhaust-gas values worsen. Have the 
vehicle checked as soon as possible.
Display of the previously described 
malfunction on Canadian models.
The lamp flashes under certain condi-
tions. This is a sign of excessive misfiring of the 
engine. In this case you should reduce speed 
and drive to the nearest BMW center as soon as 
possible. Heavy engine misfiring causes seri-
ous damage to the emission-relevant compo-
nents, especially the catalytic converter, within 
a short time.
If the fuel filler cap is not properly tight-
