Side airbag

Front airbags help protect the driver and the

front passenger by responding to frontal im‐

pacts in which safety belts alone would not

provide adequate protection.

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 provide protection as in‐

tended and may cause additional injuries due

to triggering. There is a risk of injuries or dan‐

ger to life. Follow the information on optimum

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

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.◀

Safety

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.

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.

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 restraint systems

The system generally detects children seated

in a child restraint system, particularly in child

restraint systems required by NHTSA at the

point in time when the vehicle was manufac‐

tured. After installing a child restraint system,

make sure that the indicator light for the front-

seat passenger airbags lights up. This indi‐

cates that the child restraint system has been

detected 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.

Strength of the driver's and front-seat

passenger airbag

WARNING

1. Check the tire pressure and correct as

needed.

A damaged regular tire with low or miss‐

ing tire inflation pressure impacts handling,

such as steering and braking response. Run-

flat tires can maintain limited stability. There is

a risk of an accident. Do not continue driving if

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‐

ing the area of the interference, the system

automatically becomes active again.

2. Repair the flat tire, for instance with a tire

repair kit or by changing the tire.

Use of sealant, for instance from the tire repair

kit, may damage the TPM wheel electronics. In

this case, have the electronics checked and re‐

placed at the next opportunity.

Declaration according to NHTSA/

FMVSS 138 Tire Pressure Monitoring

System

Each tire, including the spare (if provided)

should be checked monthly when cold and in‐

flated to the inflation pressure recommended

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 inflation

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

system (TPMS) that illuminates a low tire pres‐

sure telltale when one or more of your tires is

significantly 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 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‐

System limits

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.

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

may cause a warning when temperatures fall

very sharply.

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.

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.

Prewarning

The dimmed lamp in the exterior mirror hous‐

ing indicates when there are vehicles in the

blind spot or approaching from behind.

Radar sensors

Acute warning

If the turn signal is set while a vehicle is in the

critical zone, the steering wheel vibrates briefly

and the lamp in the exterior mirror housing

flashes brightly.

The warning stops when the turn signal is

switched off, or the other vehicle leaves the

critical zone.

The radar sensors are located in the rear

bumper.

Safety information

▷

When a vehicle is approaching at a speed

much faster than your own.

WARNING

The system does not release from the

personal responsibility to correctly assess

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 an acci‐

dent. Make sure that the driver is rested and

alert. Adjust the driving style to the traffic con‐

Function

Brake force display

The system is activated each time the engine

is started and cannot be switched off.

Concept

After travel has begun, the system monitors

certain aspects of the driver's behavior, so that

decreasing alertness or fatigue can be de‐

tected.

Additional brake lamps indicate emergency

braking to the traffic behind. This can reduce

the risk of a rear-end collision.

This procedure takes the following criteria into

account:

General information

▷

Personal driving style, e.g., steering behav‐

ior.

▷

Driving conditions, e.g., length of trip.

Starting at approximately 43 mph/70 km/h, the

system is active and can display a recommen‐

dation to take a break.

Break recommendation

If the driver becomes less alert or fatigued, a

message is displayed in the Control Display

with the recommendation to take a break.

▷

During normal brake application, the outer

brake lights light up.

During heavy brake application, the inner

brake lights additionally light up.

A recommendation to take a break is displayed

only once during an uninterrupted trip.

After a break, another recommendation to take

a break cannot be displayed until after approxi‐

mately 45 minutes.
