Front airbags  
Side airbag  
Front airbags help protect the driver and front  
passenger by responding to frontal impacts in  
which safety belts alone would not provide ad‐  
equate restraint.  
In a lateral impact, the side airbag supports the  
side of the body in the chest and lap area.  
Head airbag  
In a lateral impact, the head airbag supports  
the head.

Controls  
Safety  
Do not apply adhesive materials to the air‐  
bag cover panels, do not cover them or  
modify them in any way.  
Ejection Mitigation  
The head airbag system is designed as an  
ejection mitigation countermeasure to reduce  
the likelihood of ejections of vehicle occupants  
through side windows during rollovers or side  
impact events.  
Dashboard and windshield on the front  
passenger side must stay clear - do not at‐  
tach adhesive labels or coverings and do  
not attach brackets or cables, for instance  
for GPS devices or mobile phones.  
Knee airbag  
The knee airbag supports the legs in a frontal  
impact.  
Do not use the cover of the front airbag on  
the front passenger side as a storage area.  
Do not place slip covers, seat cushions or  
other objects on the front passenger seat  
that are not specifically suited for seats  
with integrated side airbags.  
Protective action  
Airbags are not triggered in every impact situa‐  
tion, e.g., in less severe accidents or rear-end  
collisions.  
Do not hang pieces of clothing, such as  
jackets, over the backrests.  
Information on optimum effect of the  
airbags  
Never modify either the individual compo‐  
nents or the wiring in the airbag system.  
This also applies to steering wheel covers,  
the dashboard, and the seats.  
WARNING  
If the seat position is incorrect or the de‐  
ployment area of the airbags is impaired, the  
airbag system cannot protect as intended or  
may cause additional injuries due to triggering.  
There is a risk of injuries or danger to life. Fol‐  
low the information on optimum protective ef‐  
fect of the airbag system.◀  
Do not remove the airbag system.  
Even when you follow all instructions very  
closely, injury from contact with the airbags  
cannot be fully ruled out in certain situations.  
The ignition and inflation noise may lead to  
short-term and, in most cases, temporary  
hearing impairment in sensitive occupants.  
Keep a distance from the airbags.  
Make sure that occupants keep their heads  
away from the side airbag.  
Vehicle modifications for a person with disabili‐  
ties may affect the air bag system; therefore,  
contact BMW Customer Relations or your au‐  
thorized BMW service center.  
Always grasp the steering wheel on the  
steering wheel rim. Hold your hands at the  
3 o'clock and 9 o'clock positions, to keep  
the risk of injury to your hands or arms as  
low as possible when the airbag is trig‐  
gered.  
Warnings and information on the airbags are  
also found on the sun visors.  
Functional readiness of the airbag  
system  
Make sure that the front passenger is sit‐  
ting correctly, i.e., keeps his or her feet and  
legs in the floor area and does not support  
them on the dashboard.  
Safety information  
WARNING  
There should be no additional persons, an‐  
imals or objects between an airbag and a  
person.  
Individual components can be hot after  
triggering of the airbag system. There is a risk  
of injury. Do not touch individual compo‐  
nents.◀

Controls  
WARNING  
Safety information  
Improperly executed work can lead to  
failure, malfunction or unintentional triggering  
of the airbag system. In the case of a malfunc‐  
tion, the airbag system might not trigger as in‐  
tended in the event of an accident despite re‐  
spective accident severity. There is a risk of  
injuries or danger to life. Have the airbag sys‐  
tem checked, repaired, dismantled and scrap‐  
ped by a dealer’s service center or another  
qualified service center or repair shop.◀  
WARNING  
To ensure the front-seat passenger air‐  
bag function, the system must be able to de‐  
tect whether a person is sitting in the front  
passenger seat. The entire seat cushion area  
must be used for this purpose. There is a risk  
of injuries or danger to life. Make sure that the  
front passenger keeps his or her feet in the  
floor area.◀  
Malfunction of the automatic  
deactivation system  
When transporting older children and adults,  
the front-seat passenger airbags may be deac‐  
tivated in certain sitting positions. In this case,  
the indicator lamp for the front-seat passenger  
airbags lights up.  
Correct function  
When the ignition is switched on, the  
warning lamp in the instrument cluster  
lights up briefly and thereby indicates  
the operational readiness of the entire airbag  
system and the belt tensioner.  
In this case, change the sitting position so that  
the front-seat passenger airbags are activated  
and the indicator lamp goes out.  
Airbag system malfunctioning  
Warning lamp does not come on when the  
ignition is turned on.  
If it is not possible to activate the airbags, have  
the person sit in the rear.  
The warning lamp lights up continuously.

Automatic deactivation of the front-  
seat passenger airbags  
Do not attach covers, cushions, ball mats  
or other items to the front passenger seat  
unless they are specifically determined to  
be safe for use on the front passenger  
seat.  
Concept  
The system reads if the front passenger seat is  
occupied by measuring the human body's re‐  
sistance.  
Do not place any electronic devices on the  
passenger seat if a child restraint system is  
to be installed on it.  
Front, knee and side airbag on the front pas‐  
senger's side are either activated or deacti‐  
vated.  
Do not place objects under the seat that  
could press against the seat from below.  
General information

the long term, calibrate the front seats as soon  
as a respective message appears on the Con‐  
trol Display.  
Calibrating the front seats  
WARNING  
There is a risk of jamming when moving  
the seats. There is a risk of injury or risk of  
property damage. Make sure that the area of  
movement of the seat is clear prior to any ad‐  
justment.◀  
The indicator lamp for the front-seat passen‐  
ger airbags indicates the operating state of the  
front-seat passenger airbags.  
The lamp indicates whether the airbags are ei‐  
ther activated or deactivated.  
A corresponding message appears on the  
Control Display.  
The indicator lamp lights up  
when a child is properly  
seated in a child restraint fix‐  
ing system or when the seat  
is empty. The airbags on the  
front passenger side are not  
activated.  
1. Press the switch and move the respective  
seat all the way forward.  
2. Press the switch forward again. The seat  
still moves forward slightly.  
3. Readjust the seat to the desired position.  
The calibration procedure is completed when  
the message on the Control Display disap‐  
pears.  
The indicator lamp does not light up when,  
e.g., a correctly seated person of sufficient  
size is detected on the seat. The airbags  
on the front passenger side are activated.  
If the message continues to be displayed, re‐  
peat the calibration.  
If the message does not disappear after a re‐  
peat calibration, have the system checked as  
soon as possible.  
Detected child seats  
The system generally detects children seated  
in a child seat, particularly in child seats re‐  
quired by NHTSA at the point in time when the  
vehicle was manufactured. After installing a  
child seat, make sure that the indicator lamp  
for the front-seat passenger airbags lights up.  
This indicates that the child seat has been de‐  
tected and the front-seat passenger airbags  
are not activated.  
Tire Pressure Monitor TPM  
Concept  
The system monitors tire inflation pressure in  
the four mounted tires. The system warns you  
if there is a significant loss of pressure in one  
or more tires. For this purpose, sensors in the  
tire valves measure the tire inflation pressure  
and tire temperature.

Safety  
Controls  
Check the air pressure in all four tires, e.g.,  
using the tire pressure gage of a tire repair  
kit.  
A vehicle with a damaged tire reacts differ‐  
ently, e.g., it has reduced lane stability during  
braking, a longer braking distance and different  
self-steering properties. Adjust your driving  
style accordingly. Avoid abrupt steering ma‐  
neuvers or driving over obstacles, e.g., curbs,  
potholes, etc.  
If the tire inflation pressure in all four tires  
is correct, the Tire Pressure Monitor may  
not have been initialized. In this case, initi‐  
alize the system.  
Because the possible driving distance de‐  
pends on how the vehicle is used during the  
trip, the actual distance may be shorter or lon‐  
ger depending on the driving speed, road con‐  
ditions, external temperature, cargo load, etc.  
If identification of flat tire damage is not  
possible, please contact a dealer’s service  
center or another qualified service center  
or repair shop.  
2. Repair the flat tire, e.g., with a tire repair kit  
or by changing the tire.  
WARNING  
Your vehicle handles differently when a  
run-flat tire is damaged and has low or missing  
tire inflation pressure, e.g., your lane stability is  
reduced when braking, braking distances are  
longer and the self-steering properties will  
change. There is a risk of an accident.  
Use of tire sealant, e.g., the Mobility System,  
may damage the TPM wheel electronics. In  
this case, have the electronics checked at the  
next opportunity and have them replaced, if  
needed.  
Run-flat tires  
Drive moderately and do not exceed a speed of  
50 mph/80 km/h.◀  
Maximum speed  
You may continue driving with a damaged tire  
at speeds up to 50 mph/80 km/h.  
Final tire failure  
Vibrations or loud noises while driving can indi‐  
cate the final failure of a tire.  
Continued driving with a flat tire  
Reduce speed and stop; otherwise, pieces of  
the tire could come loose and cause an acci‐  
dent.  
If continuing to drive with a damaged tire:  
1. Avoid sudden braking and steering maneu‐  
vers.  
Do not continue driving. Contact a dealer’s  
service center or another qualified service cen‐  
ter or repair shop.  
2. Do not exceed a speed of 50 mph/80 km/h.  
3. Check the air pressure in all four tires at  
the next opportunity.  
System limits  
If the tire inflation pressure in all four tires  
is correct, the Tire Pressure Monitor may  
not have been reset. In this case, perform  
the reset.  
The system does not function properly if a re‐  
set has not been carried out, e.g., a flat tire is  
reported though tire inflation pressures are  
correct.  
Possible driving distance with complete loss of  
tire inflation pressure:  
The tire inflation pressure depends on the  
tire's temperature. Driving or exposure to the  
sun will increase the tire's temperature, thus  
increasing the tire inflation pressure. The tire  
inflation pressure is reduced when the tire  
temperature falls again. These circumstances  
The possible driving distance with a flat tire  
depends on cargo load, driving style and road  
conditions.  
A vehicle with an average load has a possible  
driving range of approx. 50 miles/80 km.

the low tire pressure telltale illuminates, you  
should stop and check your tires as soon as  
possible, and inflate them to the proper pres‐  
sure. Driving on a significantly under-inflated  
tire causes the tire to overheat and can lead to  
tire failure. Under-inflation also reduces fuel ef‐  
ficiency and tire tread life, and may affect the  
vehicle's handling and stopping ability. Please  
note that the TPMS is not a substitute for  
proper tire maintenance, and it is the driver's  
responsibility to maintain correct tire pressure,  
even if under-inflation has not reached the  
level to trigger illumination of the TPMS low  
tire pressure telltale. Your vehicle has also  
been equipped with a TPMS malfunction indi‐  
cator to indicate when the system is not oper‐  
ating properly. The TPMS malfunction indica‐  
tor is combined with the low tire pressure  
telltale. When the system detects a malfunc‐  
tion, the telltale will flash for approximately one  
minute and then remain continuously illumi‐  
nated. This sequence will continue upon sub‐  
sequent vehicle start-ups as long as the mal‐  
function 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 replace‐  
ment or alternate tires or wheels on the vehicle  
that prevent the TPMS from functioning prop‐  
erly. Always check the TPMS malfunction tell‐  
tale 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.  
The system cannot indicate sudden serious  
tire damage caused by external circumstances.  
Malfunction  
The yellow warning lamp flashes and  
then lights up continuously. A Check  
Control message is displayed. No flat  
tire or loss of tire inflation pressure can be de‐  
tected.  
Examples and recommendations in the follow‐  
ing situations:  
A wheel without TPM electronics is  
mounted: Have it checked by a dealer’s  
service center or another qualified service  
center or repair shop as needed.  
Malfunction: Have system checked by a  
dealer’s service center or another qualified  
service center or repair shop.  
TPM was unable to complete the reset.  
Reset the system again.  
Interference caused by systems or devices  
with the same radio frequency: After leav‐

Collision warning with  
braking function  
Detection range  
The system's detection potential is limited.  
The concept  
The system can help prevent accidents. If an  
accident cannot be prevented, the system will  
help reduce the collision speed.  
Thus, a system reaction might not come or  
might come late.  
E.g., the following situations may not be de‐  
tected:  
The system sounds a warning before an immi‐  
nent collision and actuates brakes independ‐  
ently if needed.  
Slow moving vehicles when you approach  
them at high speed.  
The automatic braking intervention may be  
executed with maximum braking force and for  
a brief period only as necessary.  
Vehicles that suddenly swerve in front of  
you, or sharply decelerating vehicles.  
Vehicles with an unusual rear appearance.  
Two-wheeled vehicles ahead of you.  
If the vehicle is equipped with Active Cruise  
Control with Stop&Go, the front-end collision  
warning is controlled via the cruise control ra‐  
dar sensor in conjunction with a camera.  
Functional limitations  
The system may not be fully functional in the  
following situations:  
The front-end collision warning is available  
even if cruise control has been deactivated.  
In heavy fog, rain, sprayed water or snow‐  
fall.

Concept  
The system's detection potential is limited.  
The system can help prevent accidents with  
pedestrians.  
Thus, a system reaction might not come or  
might come late.  
When driving at city speeds, the system will is‐  
sue a warning if there is imminent danger of a  
collision with pedestrians and includes a brak‐  
ing function.  
E.g., the following situations may not be de‐  
tected:  
Slow moving vehicles when you approach  
them at high speed.  
The camera in the area of the rearview mirror  
controls the system.  
Vehicles that suddenly swerve in front of  
you, or sharply decelerating vehicles.

General information  
With sufficient brightness, the system warns  
about possible collision danger with pedes‐  
trians starting at approx. 6 mph/10 km/h to ap‐  
prox. 35 mph/60 km/h and assists with braking  
before a collision.
