RResestrtraint systaint systemem

ProtProtection proection provided bvided by ty the rhe resestrtraint systaint systemem

The restraint system includes the following com-

ponents:

Seat belt system

Airbags

Child restraint system

Child seat securing systems

The restraint system can help prevent the vehicle

occupants from coming into contact with parts of

the vehicle interior in the event of an accident. In

the event of an accident, the restraint system can

also reduce the forces to which the vehicle occu-

pants are subjected.

A seat belt can only provide the best level of pro-

tection if it is worn correctly. Depending on the

detected accident situation, Emergency Tension-

ing Devices and/or airbags supplement the pro-

tection oered by a correctly worn seat belt.

Emergency Tensioning Devices and/or airbags

are not deployed in every accident.

In order for the restraint system to provide the

intended level of protection, each vehicle occu-

pant must observe the following information:

Fasten seat belts correctly.

Sit in an almost upright seat position with their

back against the seat backrest.

Sit with their feet resting on the oor, if possi-

ble.

Always secure persons under 5  (1.50 m) tall

in an additional restraint system suitable for

Mercedes-Benz vehicles.

However, no system available today can com-

pletely eliminate injuries and fatalities in every

accident situation. In particular, the seat belt and

airbag generally do not protect against objects

penetrating the vehicle from the outside. It is also

not possible to completely rule out the risk of

injury caused by the airbag deploying.

Occupant safety

RResestrtraint systaint system functionalityem functionality

When the vehicle is switched on, a self-test is per-

formed, during which the 6 restraint system

warning lamp lights up. It goes out no later than a

few seconds aer the vehicle is started. The com-

ponents of the restraint system are then func-

tional.

Malfunctioning rMalfunctioning resestrtraint systaint systemem

A malfunction has occurred in the restraint sys-

tem if:

The 6 restraint system warning lamp does

not light up when the vehicle is switched on

The 6 restraint system warning lamp lights

up continuously or repeatedly during a journey

WARNINGARNING Risk of injury due to malfunc-

tions in the restraint system

Components in the restraint system may be

activated unintentionally or not deploy as plan-

ned in an accident.

Have the restraint system checked and

repaired immediately at a qualied spe-

cialist workshop.

FFunction of tunction of the rhe resestrtraint systaint system in an accidentem in an accident

How the restraint system works depends on the

severity of the impact detected and the apparent

type of accident:

Frontal impact

Rear impact

Side impact

Rollover

The activation thresholds for the components of

the restraint system are determined based on the

evaluation of the sensor values measured at vari-

ous points in the vehicle. This process is pre-emp-

tive in nature. The triggering/deployment of the

components of the restraint system must take

place in good time at the start of the collision.

Factors which can only be seen and measured

aer a collision has occurred cannot play a deci-

sive role in airbag deployment. Nor do they pro-

vide an indication of airbag deployment.

The vehicle may be deformed signicantly without

an airbag being deployed. This is the case if only

parts which are relatively easily deformed are

aected and the rate of vehicle deceleration is

not high. Conversely, an airbag may be deployed

even though the vehicle suers only minor defor-

mation. If very rigid vehicle parts such as longitu-

dinal members are hit, this may result in su-

ciently high levels of vehicle deceleration.

Depending on the detected deployment situation,

the components of the restraint system can be

activated or deployed independently of each

other:

Emergency Tensioning Device: frontal impact,

rear impact, side impact, rollover

Driver's airbag, front passenger airbag: frontal

impact

Knee airbag: frontal impact

Side airbag: side impact

Window curtain airbag: side impact, rollover,

frontal impact

3838

Occupant safety

The front passenger airbag can only be deployed

in an accident if the PASSENGER AIR BAG OFF

indicator lamp is o. If the front passenger seat is

occupied, make sure, both before and during the

journey, that the status of the front passenger air-

bag is correct (/ page 48).

WARNINGARNING Risk of burns from hot air bag

components

The air bag parts are hot aer an air bag has

been deployed.

Do not touch the air bag parts.

Have a deployed air bag replaced at a

qualied specialist workshop as soon as

possible.

Mercedes-Benz recommends that you have the

vehicle towed to a qualied specialist workshop

aer an accident. Take this into account, particu-

larly if an Emergency Tensioning Device is trig-

gered or an airbag deployed.

If the Emergency Tensioning Devices are triggered

or an airbag is deployed, you will hear a bang, and

a small amount of powder may also be released:

The bang will not generally aect your hearing.

In general, the powder released is not hazard-

ous to health but may cause short-term

breathing diculties to persons suering from

asthma or other pulmonary conditions.

Provided it is safe to do so, leave the vehicle

immediately or open the window in order to

prevent breathing diculties.

Airbags and pyrotechnic Emergency Tensioning

Devices contain perchlorate material, which may

require special handling or environmental protec-

tion measures. National guidelines regarding

waste disposal must be observed. In California,

see Using the search func-

tion, you will nd information on perchlorate, for

example.

Seat beltsSeat belts

ProtProtection proection provided bvided by ty the seat belthe seat belt

Always fasten your seat belt correctly before

starting a journey. A seat belt can only provide

the best level of protection if it is worn correctly.

WARNINGARNING Risk of injury or death due to

incorrectly fastened seat belt

If the seat belt is not worn correctly, it cannot

perform its intended protective function.

In addition, an incorrectly fastened seat belt

can also cause injuries, for example, in the

event of an accident or when braking or

changing direction suddenly.

Always ensure that all vehicle occupants

have their seat belts fastened correctly

and are sitting properly.

Always observe the instructions about the correct

driver's seat position and adjusting the seat

(/ page 88).

Occupant safety

In order for the correctly worn seat belt to provide

the intended level of protection, each vehicle

occupant must observe the following information:

The seat belt must not be twisted and must t

tightly and snugly across the body.

The seat belt must be routed across the cen-

ter of the shoulder and as low down across

the hips as possible.

The shoulder section of the seat belt should

not touch your neck nor be routed under your

arm or behind your back.

Avoid wearing bulky clothing, e.g. a winter

coat.

Push the lap belt down as far as possible

across your hips and pull tight with the shoul-

der section of the belt. Never route the lap

belt across your abdomen.

Pregnant women must also take particular

care with this.

Never route the seat belt across sharp, poin-

ted, abrasive or fragile objects.

Only one person should use each seat belt at

any one time.

Never secure objects with a seat belt if the

seat belt is also being used by one of the vehi-

cle's occupants.

Also ensure that no objects, e.g. a cushion,

are ever placed between a person and the

seat.

The seat belts on the following seats are equipped

with a child seat safety feature:

Front passenger seat

Rear seats

Activate or deactivate the child seat safety feature

of the seat belt (/ page 56).

If children are traveling in the vehicle, be sure to

observe the instructions and safety notes on

"Children in the vehicle" (/ page 53).

Always observe the instructions for loading the

vehicle when securing objects, luggage or loads

(/ page 101).

WARNINGARNING Risk of injury or death due to

an incorrect seat position

The seat belt does not oer the intended level

of protection if you have not moved the seat

backrest to an almost vertical position.

In particular, you could slip beneath the seat-

belt and become injured.

Adjust the seat properly before begin-

ning your journey.

Always ensure that the seat backrest is

in an almost vertical position and that

the shoulder belt is routed across the

center of your shoulder.

Occupant safety

Always secure persons under 5 

(1.50 m) tall in a suitable restraint sys-

tem.

WARNINGARNING Risk of injury or death due to

damaged or modied seat belts

Seat belts cannot provide protection in the fol-

lowing situations:

The seat belt is damaged, has been modi-

ed, is extremely dirty, bleached or dyed

The seat belt buckle is damaged or

extremely dirty

Modications have been made to the

Emergency Tensioning Device, seat belt

anchorage or seat belt retractor

Seat belts may sustain non-visible damage in

an accident, e.g. due to glass splinters.

Modied or damaged seat belts could tear or

fail in the event of an accident, for example.

Modied Emergency Tensioning Devices could

accidentally trigger or fail to function as inten-

ded.

Never modify the seat belt system, for

example the seat belt, seat belt buckle,

Emergency Tensioning Device, seat belt

anchorage and seat belt retractor.

Make sure that the seat belts are undam-

aged, not worn and clean.

Always have the seat belts checked

immediately aer an accident at a quali-

ed specialist workshop.

Only use seat belts which have been approved for

your vehicle by Mercedes-Benz.

The sports seat is designed for the standard

three-point seat belt. If you install a dierent mul-

tipoint seat belt, for example a four-point seat

belt, the restraint system cannot provide the

intended level of protection.

Depending on the type of vehicle, there may be

openings in the seat backrest. These openings

have no function.

WARNINGARNING Risk of injury or fatal injury due

to modied seat belt systems

If you feed seat belts through the opening in

the seat backrest, the seat backrest may be

damaged or may even break in the event of an

accident.

Only use the standard three-point seat

belt.

Never modify the seat belt system.

WARNINGARNING Risk of injury or death from

deployed pyrotechnic Emergency Tension-

ing Devices

Pyrotechnic Emergency Tensioning Devices

that have been deployed are no longer opera-

tional and are unable to perform their inten-

ded protective function.

Therefore, have deployed pyrotechnic

Emergency Tensioning Devices immedi-

ately replaced at a qualied specialist

workshop.

Occupant safety

Mercedes-Benz recommends that you have the

vehicle towed to a qualied specialist workshop

aer an accident.

NOOTETE Damage caused by trapping the

seat belt

Only use the following securing systems for child

restraint systems:

The LATCH-type (ISOFIX) securing rings

The vehicle's seat belt system

The Top Tether anchorages

Installing a LATCH-type (ISOFIX) child restraint

system is preferred.

Simply attaching to the securing rings on the vehi-

cle can reduce the risk of installing the child

restraint system incorrectly.

When securing a child with the integrated seat

belt of the LATCH-type (ISOFIX) child restraint

system, always comply with the permissible gross

weight for the child and child restraint system

(/ page 57).

A booster seat may be necessary to achieve

proper seat belt positioning for children over

40 lbs (18 kg) in weight or until they reach a

height where a three-point seat belt can be fas-

tened properly without a booster seat.

Mercedes-Benz recommends a suitable child

booster seat with a backrest and seat belt guide.

Advdvantantagage of a re of a rearwearwarard-fd-facing cacing child rhild resestrtraint syaint sys-s-

It is preferable to transport a baby or a small child

in a suitable rearward-facing child restraint sys-

tem. In this case, the child sits in the opposite

direction to the direction of travel and faces back-

wards.

Babies and small children have comparatively

weak neck muscles in relation to the size and

weight of their head. The risk of injury to the cer-

vical spine during an accident can be reduced in a

rearward-facing child restraint system.
