Front airbags

Side airbag

Front airbags help protect the driver and the

front passenger by responding to frontal impacts

in which safety belts alone would not provide ad‐

equate protection.

In the event of a side impact, the side airbag pro‐

tects the side of the body in the chest, lap, and

head area.

152

Safety

CONTROLS

▷ Do not apply adhesive materials to the airbag

cover panels, do not cover them or modify

them in any way.

Knee airbag

The knee airbag protects the legs in the event of

a frontal impact.

▷ Do not use the cover of the front airbag on

the front passenger side as a storage area.

Protective effect

General information

Airbags are not triggered in every impact situa‐

tion, e.g., in less severe accidents.

▷ Do not attach slip covers, seat cushions or

other objects to the front passenger seat that

are not specifically suited for seats with

integrated side airbags.

▷ Do not hang pieces of clothing, such as jack‐

ets, 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 deploy‐

ment area of the airbags is impaired, the airbag

system cannot provide protection as intended

and may cause additional injuries due to trig‐

gering. There is a risk of injuries or danger to

life. Follow the information on achieving the op‐

timum protective effect of the airbag system.

▷ Do not remove the airbag system.

Even when you follow all instructions very

closely, injury from contact with the airbags can‐

not be fully ruled out in certain situations.

The ignition and inflation noise may lead to

short-term and, in most cases, temporary hear‐

ing impairment in sensitive occupants.

▷ Keep a distance from the airbags.

Vehicle modifications for a person with disabili‐

ties may affect the air bag system; contact BMW

Customer Relations for further information.

▷ 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 triggered.

Warnings and information on the airbags are also

found on the sun visors.

▷ Make sure that the front passenger is sitting

correctly, i.e., keeps his or her feet and legs in

the floor area and does not support them on

the dashboard.

Functional readiness of the

airbag system

Safety information

▷ Make sure that occupants keep their heads

away from the side airbag.

Warning

▷ There should be no additional persons, ani‐

mals or objects between an airbag and a per‐

son.

Individual components can be hot after trigger‐

ing of the airbag system. There is a risk of in‐

jury. Do not touch individual components.

▷ Dashboard and windshield on the front pas‐

senger side must stay clear - do not attach

adhesive labels or coverings and do not at‐

tach brackets or cables, for instance for GPS

devices or mobile phones.

Safety

CONTROLS

Warning

Calibrating the front seats

Improperly executed work can lead to failure,

malfunction or unintentional triggering of the

airbag system. In the case of a malfunction, the

airbag system might not trigger as intended de‐

spite the accident severity. There is a risk of in‐

juries or danger to life. Have the airbag system

checked, repaired, dismantled and scrapped by

a dealer’s service center or another qualified

service center or repair shop.

Warning

There is a risk of jamming when moving the

seats. There is a risk of injury or risk of damage

to property. Make sure that the area of move‐

ment of the seat is clear prior to any adjust‐

ment.

A corresponding message appears on the Con‐

trol Display.

1. Press the switch and move the respective

seat all the way forward, until it stops.

Display in the instrument cluster

When drive-ready state is switched on,

the warning light in the instrument clus‐

ter lights up briefly and thereby indicates

the function readiness of the entire airbag sys‐

tem and the belt tensioners.

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 disappears.

If the message continues to be displayed, repeat

the calibration.

Malfunction

▷ Warning light does not come on

when drive-ready state is switched

on.

If the message does not disappear after a repeat

calibration, have the system checked as soon as

possible.

▷ The warning light lights up continuously.

Have the system checked.

Automatic deactivation of

the front-seat passenger

airbags

Strength of the driver's and

front-seat passenger airbag

The explosive power that activates driver's/front-

seat passenger airbags very much depends on

the positions of the driver's/front passenger seat.

Concept

The system reads if the front passenger seat is

occupied by measuring the human body's resist‐

ance.

To maintain the accuracy of this function over

the long term, calibrate the front seats as soon as

a respective message appears on the Control

Display.

Front, knee, and side airbag on the front pas‐

senger's side are activated or deactivated.

General information

Before transporting a child on the front passen‐

ger seat, refer to the safety information and in‐

structions for children on the front passenger

seat, see Children.

154

Safety

CONTROLS

Safety information

Indicator light for the front-seat

passenger airbags

The indicator light for the front-seat passenger

airbag in the roofliner indicates the operating

state of the front-seat passenger airbag.

Warning

To ensure the front-seat passenger airbag

function, the system must be able to detect

whether a person is sitting in the front passen‐

ger 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 pas‐

senger keeps his or her feet in the floor area.

The light indicates whether the airbags are either

activated or deactivated.

After drive-ready state is switched on, the light

briefly lights up and then indicates whether the

airbags are either activated or deactivated.

▷ The indicator light lights up

when a child is properly

seated in a child restraint sys‐

tem or when the seat is

empty. The airbags on the

front passenger side are not

activated.

Malfunction of the automatic

deactivation system

When transporting older children and adults, the

front-seat passenger airbags may be deactivated

in certain sitting positions. In this case, the indi‐

cator light for the front-seat passenger airbags

lights up.

▷ The indicator light does not light up when, for

instance a correctly seated person of suffi‐

cient size is detected on the seat. The air‐

bags on the front passenger side are acti‐

vated.

In this case, change the sitting position so that

the front-seat passenger airbags are activated

and the indicator light goes out.

If it is not possible to establish the desired condi‐

tion, do not transport the person in the front pas‐

senger seat.

Detected child restraint systems

The system generally detects children seated in

a child restraint system, particularly in child re‐

straint systems required by NHTSA at the point

in time when the vehicle was manufactured. Af‐

ter installing a child restraint system, make sure

that the indicator light for the front-seat passen‐

ger airbags lights up. This indicates that the child

restraint system has been detected and the

front-seat passenger airbags are not activated.

To enable correct recognition of the occupied

seat cushion.

▷ Do not attach covers, cushions, ball mats or

other items to the front passenger seat un‐

less they are specifically determined to be

safe for use on the front passenger seat.

▷ Do not place any electronic devices on the

front passenger seat if a child restraint sys‐

tem is to be installed on it.

▷ Do not place objects under the seat that

could press against the seat from below.

Intelligent Safety

▷ No moisture in or on the seat.

Concept

Intelligent Safety enables central operation of the

driver assistance systems.

Braking intervention

Warning with braking function

Display

A warning symbol appears in the instrument

cluster and in the Head-up Display, where availa‐

ble, if a collision with a detected vehicle is immi‐

nent.

The warning prompts the driver to intervene. If a

warning is active, the maximum braking force is

used when the brake is applied. The brake pedal

must be applied sufficiently quickly and force‐

fully.

The system may also assist in braking if there is

a risk of collision.

Symbol Measure

When the vehicle is traveling at a low speed, the

vehicle may come to a complete stop.

Symbol lights up red: prewarning.

Brake and increase distance.

City brake function: the braking intervention oc‐

curs to up to approx. 50 mph/80 km/h.

With radar sensor: the braking intervention oc‐

curs to up to approx. 155 mph/250 km/h.

Symbol flashes red and an acoustic

signal sounds: acute warning.

At speeds above approx. 130 mph/210 km/h, the

braking intervention occurs as a brief braking

pressure. No automatic delay occurs.

Brake and make an evasive maneu‐

ver, if necessary.

The braking intervention occurs only if vehicle

stability has not been restricted, for instance by

deactivating the DSC Dynamic Stability Control.

Prewarning

This warning is provided, for instance when there

is impending danger of a collision or the distance

to the vehicle ahead is too small.

The driver may interrupt the braking intervention

function by stepping on the accelerator pedal or

by actively moving the steering wheel.

If a prewarning is provided, respond by braking

as warranted.

The system’s ability to detect objects may be

limited in some circumstances. Refer to the in‐

formation in this Owner’s Manual regarding the

limitations of the system and actively intervene

as warranted.

Acute warning with braking function

An acute warning is displayed in case of the im‐

minent danger of a collision when the vehicle ap‐

proaches another object at a high differential

speed.

Intervene in the case of an acute warning. De‐

pending on the driving situation, the acute warn‐

ing may be accompanied by a brief activation of

the braking system.

▷ If there are constant blinding effects because

of oncoming light, for instance from the sun

low in the sky.

The system's detection potential is limited.

Only objects that are detected by the system are

taken into account.

Attaching any objects such as stickers or film in

the beam area of the radar sensors will also im‐

pact the function of the radar sensors and may

even cause them to fail.

Thus, a system reaction might not come or

might come late.

The following situations may not be detected, for

instance:

Warning sensitivity

The more sensitive the warning settings are, for

example the warning time, the more warnings are

displayed. Therefore, there may also be an ex‐

cess of premature or unjustified warnings and re‐

The system responds to pedestrians and cyclists

when the speed of the vehicle is below approx.

50 mph/80 km/h.

Intervene immediately by braking or make an

evasive maneuver.

Detection range

The system's detection potential is limited.

Braking intervention

The warning prompts the driver to intervene. If a

warning is active, the maximum braking force is

used when the brake is applied. This requires the

brake pedal to be depressed sufficiently quickly

and forcefully.

Thus, a warning might not be issued or be is‐

sued late.

The following situations may not be detected, for

instance:

▷ Partially covered pedestrians.

If there is a risk of collision, the system may also

assist with braking.

▷ Pedestrians that are not detected as such be‐

cause of the viewing angle or contour.

When the vehicle is traveling at a low speed, the

vehicle may come to a complete stop.

▷ Pedestrians outside of the detection range.

The braking intervention occurs only if vehicle

stability has not been restricted, for instance by

deactivating the DSC Dynamic Stability Control.

▷ Pedestrians having a body size less than

32 in/80 cm.

keep the vehicle in the lane. The steering inter‐

vention can be noticed on the steering wheel

and can be manually overridden at any time. Dur‐

ing an active steering intervention, the display in

the instrument cluster will blink.

The setting is applied to all Intelligent Safety sys‐

tems and stored for the driver profile currently

used.

Switching steering intervention

on/off

The steering intervention can be switched on

and off separately for blind spot collision warning

and lane departure warning.

tions by the system within 3 minutes without the

driver's intervention at the steering wheel, an

acoustic warning will sound. A short warning sig‐

nal will sound at the second steering interven‐

tion. Beginning with the third steering interven‐

tion, an continuous warning will sound.

PostCrash – iBrake

Concept

In the event of an accident, the system can bring

the vehicle to a halt automatically without inter‐

vention by the driver in certain situations. This

can reduce the risk of a further collision and the

consequences thereof.

Upper speed limit

If the vehicle speed exceeds approx.

155 mph/250 km/h, the system is deactivated

temporarily.

At standstill

After coming to a halt, the brake is released auto‐

matically.

If the vehicle speed falls below approx.

155 mph/250 km/h, the system once again re‐

sponds according to the setting.

Harder vehicle braking

In certain situations, it can be necessary to bring

the vehicle to a halt more quickly than the Brake

Assistant allows.

Functional limitations

The system may not be fully functional in the fol‐

lowing situations:

To do this, quickly apply extra force to the brake.

For a brief period, the braking pressure will be

higher than the braking pressure that is achieved

by the automatic braking function. Automatic

braking is interrupted.

▷ When a vehicle is approaching at a speed

much faster than your own.

▷ In heavy fog, wet conditions, or snowfall.

▷ In tight curves or on narrow lanes.

Interrupting automatic braking

It can be necessary to interrupt automatic brak‐

ing in certain situations, for instance for an eva‐

sive maneuver.

▷ If the bumper is dirty, iced up, or covered,

for instance by stickers.

▷ If cargo protrudes.

Attaching any objects such as stickers or film in

the beam area of the radar sensors will also im‐

pact the function of the radar sensors and may

even cause them to fail.

Interrupt automatic braking:

▷ By pressing the brake pedal.

▷ By pressing the accelerator pedal.

A Check Control message is displayed when the

system is not fully functional.

Fatigue alert

Via iDrive:

General information

1. "CAR"

The system can detect decreasing alertness or

fatigue of the driver during long, monotonous

trips, for instance on highways. In this situation, it

is recommended that the driver takes a break.

2. "Settings"

3. "General settings"

4. "Fatigue and Focus Alert"

5. Select the desired setting:

Safety information

▷ "Standard": the break recommendation is

made with a defined value.

Warning

▷ "Sensitive": the break recommendation is

issued earlier.

The system cannot serve as a substitute for the

driver’s personal judgment in assessing one's

physical state. An increasing lack of alertness or

fatigue may not be detected or not be detected

in time. There is a risk of accident. Make sure

that the driver is rested and alert. Adjust driving

style to traffic conditions.

▷ "Off": no break recommendation is made.

Display

If the driver becomes less alert or fatigued, a

message is displayed in the Control Display with

the recommendation to take a break.

During the display, various settings can be se‐

lected.

Function

The system is switched on each time drive-ready

state is switched on.

After a break, another recommendation to take a

break cannot be displayed until after approxi‐

mately 45 minutes.

After travel has begun, the system monitors cer‐

tain aspects of the driver's behavior, so that de‐

creasing alertness or fatigue can be detected.

System limits

This procedure takes the following criteria into

account:

The function may be limited in the following sit‐

uations and may issue an incorrect warning or no

warning at all:

▷ Personal driving style, for instance steering

behavior.

▷ When the clock is set incorrectly.

▷ Driving conditions, for instance time, length of

trip.

▷ When the vehicle speed is mainly below

about 43 mph/70 km/h.

Starting at approx. 43 mph/70 km/h, the system

is active and can also display a recommendation

to take a break.

▷ With a sporty driving style, such as during

rapid acceleration or when cornering fast.

▷ In active driving situations, such as when

changing lanes frequently.

Break recommendation

Adjusting

▷ When the road surface is poor.

▷ In the event of strong side winds.

The system is reset approx. 45 minutes after

parking the vehicle, for instance in the case of a

break during longer trips on highways.

The fatigue alert is active automatically with each

switching on of drive-ready state and can thus

display a break recommendation.
