Side airbags

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 airbags

In a lateral impact, the head airbag supports

the head.

Safety

Controls

▷

Make sure that occupants keep their heads

away from the side airbag and do not rest

against the head airbag; otherwise, injuries

might occur when airbag is activated.

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.

▷

Do not remove the airbag system.

Do not remove the steering wheel.

Do not apply adhesive materials to the air‐

bag cover panels, do not cover them or

modify them in any way.

Knee airbag

The knee airbag supports the legs in a frontal

impact.

▷

Never modify either the individual compo‐

nents or the wiring in the airbag system.

This also applies to steering wheel covers,

the dashboard, the seats, the roof pillars

and the sides of the roofliner.◀

Protective action

Airbags are not triggered in every impact situa‐

tion, e.g., in less severe accidents or rear-end

collisions.

Even when you follow all instructions very

closely, injury from contact with the airbags

cannot be ruled out in certain situations.

Information on how to ensure the optimal

protective effect of the airbags

▷

Keep at a distance from the airbags.

The ignition and inflation noise may lead to

short-term and, in most cases, temporary

hearing impairment in sensitive individuals.

Always grasp the steering wheel on the

steering wheel rim, holding 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.

Malfunction, deactivation and after de‐

ploying the airbags

Do not touch the individual components imme‐

diately after the system has been triggered;

otherwise, you may risk burns.

▷

There should be no person, animals, or ob‐

jects between an airbag and a person.

Only have the airbags checked, repaired or dis‐

mantled and the airbag generator scrapped by

the service center or an authorized repair shop

for handling explosives.

Do not use the cover of the front airbag on

the front passenger side as a storage area.

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, e. g., for GPS

devices or' mobile phones.

Non-professional attempts to service the sys‐

tem could lead to failure in an emergency or

unintentional activation of the airbag - both

may lead to injury.◀

▷

Make sure that the front passenger is sit‐

ting correctly, i.e., keeps his or her feet and

legs in the footwell; otherwise, leg injuries

might occur when front airbag is activated.

Warnings and information on the airbags are

also found on the sun visors.

Functional readiness of the airbag

system

Do not place slip covers, seat cushions or

other objects on the front passenger seat

that are not approved specifically for seats

with integrated side airbags.

When the ignition is reel on, the warn‐

ing lamp in the instrument cluster lights

up briefly and thereby indicates the op‐

erational 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.

If it is not possible to activate the airbags, have

the person sit in the rear.

Airbag system malfunctioning

seat cushion

▷

The warning lamp lights up continuously.

▷

Do not attach covers, cushions, ball mats

or other items to the front passenger seat

unless they are specifically recommended

by your vehicle's manufacturer.

In case of a malfunction have airbag sys‐

tem checked immediately.

In case of a malfunction have airbag system

checked immediately; otherwise, there is a risk

that the system does not function as expected

in case of a severe accident.◀

▷

Do not place any electronic devices on the

passenger seat if a child restraint system is

to be installed on it.

▷

Do not place objects under the seat that

could press against the seat from below.

Automatic deactivation of the front-

seat passenger airbags

The system reads if the front passenger seat is

occupied by measuring the human body's re‐

sistance.

No moisture in or on the seat.

Indicator lamp for the front-seat

passenger airbags

Front, knee and side airbag on the front pas‐

senger's side are either activated or deacti‐

vated.

Leave feet in the footwell

Make sure that the front passenger

keeps his or her feet in the footwell; otherwise,

proper functioning of the front passenger air‐

bag might not be assured.◀

Child restraint fixing system in the front

passenger seat

The indicator lamp for the front-seat passen‐

ger airbags indicates the operating state of the

front-seat passenger airbags.

Before transporting a child on the front pas‐

senger seat, refer to the safety notes and in‐

structions for children on the front passenger

seat, see Children.◀

The lamp indicates whether the airbags are ei‐

ther activated or deactivated.

▷

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.

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.

size is detected on the seat. The airbags

on the front passenger side are activated.

Unobstructed area of movement

Ensure that the area of movement of the

seats is unobstructed to avoid personal injury

or damage to objects.◀

Detected child seats

The system generally detects children seated

in a child seat, particularly in child seats re‐

quired by NHTSA when the vehicle was manu‐

factured. 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 detected and the

front-seat passenger airbags are not activated.

Tire Pressure Monitor TPM

The 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

The explosive power that activates driver's/

front passenger's airbags very much depends

on the positions of the driver's/front passeng‐

er's seat.

Hints

Tire damage due to external factors

Sudden tire damage caused by external

circumstances cannot be recognized in ad‐

vance.◀

trol Display calibrate the front seats to keep

the accuracy of this function over the long-

term.

With use of the system observe further infor‐

mation found under Tire inflation pressure, re‐

fer to page 172.

Calibrating the front seats

A corresponding message appears on the

Functional requirements

The system must have been reset with the

correct tire inflation pressure; otherwise, relia‐

ble signaling of tire inflation pressure loss is

not assured.

1. Press the reel and move the respective

seat all the way forward.

2. Press the reel forward again. The seat still

moves forward slightly.

Reset the system after each adjustment of the

tire inflation pressure and after every tire or

wheel change.

3. Readjust the seat to the desired position.

The calibration procedure is completed when

the message on the Control Display disap‐

pears.

Always use wheels with TPM electronics to

ensure that the system will operate properly.

If the message continues to be displayed, re‐

peat the calibration.

Interference through systems or devices

with the same radio frequency: after leav‐

ing the area of the interference, the system

automatically becomes active again.

▷

The system has detected a wheel change,

but no reset was done.

Inflation was not carried out according to

specifications.

Declaration according to NHTSA/

FMVSS 138 Tire Pressure Monitoring

System

The tire inflation pressure has fallen below

the level of the last confirmation.

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‐

In this case:

▷

Check the tire pressure and correct as

needed.

▷

Carry out a reset of the system after a tire

change.

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.

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.

Display in the following situations:

▷

A wheel without TPM electronics is fitted:

have the service center check it if needed.

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.

Safety

Controls

After travel has begun, the system is trained

about the driver, so that increasing lack of

alertness or fatigue can be detected.

Brake force display

The concept

This procedure takes the following criteria into

account:

▷

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.

▷

During normal brake application, the outer

brake lights light up.

Break recommendation

If the driver becomes increasingly less alert or

fatigued, a message is displayed in the Control

Display with the recommendation to take a

break.

During heavy brake application, the inner

brake lights light up in addition.

A recommendation to take a break is displayed

only once during an uninterrupted trip.

Attentiveness assistant

After a break, another recommendation to take

a break cannot be displayed until after approxi‐

mately 45 minutes.

The concept

The system can detect increasing lack of alert‐

ness or fatigue of the driver during long, mo‐

notonous journeys, e.g., on highways. In this

situation, it is recommended that the driver

takes a break.

System limits

The function may be limited in the following

situations, for instance, and will either output

an incorrect warning or no warning at all:

Note

▷

When the clock is set incorrectly.

Personal responsibility

When the vehicle speed is mainly below

about 43 mph/70 km/h.

The system cannot act as a substitute for

the personal assessment of one's physical

state and may not detect an increasing lack of

alertness or fatigue or may not detect it cor‐

rectly. Therefore, make sure that the driver is

rested and alert; otherwise, risks may be de‐

tected too late and an accident be caused as a

result.◀

▷

With a sporty driving style, such as during

rapid acceleration or when cornering fast.

In active driving situations, such as when

changing lanes frequently.

▷

When the road surface is poor.

In the event of strong side winds.

Function

The system is activated each time the engine

is started and cannot be switched off.
