Get Occupant safety -> Seat belts Guide for Mercedes CLA 4 Door Second Generation (2019-2024)

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).

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

may become trapped in the door or in the seat

mechanism.

Always ensure that an unused seat belt

is fully retracted.

FFastastening seat beltsening seat belts

If the seat belt is pulled quickly or sharply, the

seat belt retractor locks. The seat belt strap can-

not be pulled out any further.

Always engage seat belt tongue 2 of the seat

belt into seat belt buckle

1 of the corre-

sponding seat.

A seat belt can only provide the best level of

protection if it is worn correctly. Observe the

notes on fastening the seat belt (/ page 39).

NOOTETE Deployment of components of the

restraint system when the front passenger

seat is unoccupied and a seat belt is

When the front passenger seat is unoccupied

and the seat belt tongue of the seat belt is

engaged in the seat belt buckle, components

of the restraint system may deploy unnecessa-

rily on the front passenger side, e.g. the Emer-

gency Tensioning Device.

Only buckle the seat belts as intended.

Observe the notes on storage areas

(/ page 101).
