Occupant safety

Reduced restraint system protection

In order for the restraint system to provide the

intended level of protection, each vehicle occu-

pant must observe the following information:

Restraint system

Protection provided by the restraint system

WARNING Risk of injury or death due to

modiꢃcations to the restraint system

The restraint system includes the following com-

ponents:

Fasten seat belts correctly.

Vehicle occupants may no longer be protected

as intended if alterations are made to the

restraint system.

Sit in an almost upright seat position with their

back against the seat backrest.

Airbags

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

ble.

Always secure persons under 5 ꢂ (1.50 m) tall

in an additional restraint system suitable for

Mercedes-Benz vehicles.

Never tamper with the wiring or any elec-

tronic component parts or their soꢂ-

ware.

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 oꢀered by a correctly worn seat belt.

Emergency Tensioning Devices and/or airbags

are not deployed in every accident.

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.

If it is necessary to modify the vehicle to accom-

modate a person with disabilities, contact an

authorized Mercedes-Benz Center for details.

tance Center on 1-800-FOR-MERCedes

Restraint system functionality

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

formed, during which the 6 restraint system

Occupant safety

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

few seconds aꢂer the vehicle is started. The com-

ponents of the restraint system are then func-

tional.

not high. Conversely, an airbag may be deployed

even though the vehicle suꢀers only minor defor-

mation. If very rigid vehicle parts such as longitu-

dinal members are hit, this may result in suꢄ-

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:

How the restraint system works is determined by

the severity of the impact detected and the type

of accident anticipated:

Frontal impact

Malfunctioning restraint system

Rear impact

A malfunction has occurred in the restraint sys-

tem if:

Side impact

Rollover

The 6 restraint system warning lamp does

not light up when the vehicle is switched on

Emergency Tensioning Device: 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

aꢂer a collision has occurred do not play a deci-

sive role in the deployment of an airbag. Nor do

they provide an indication of airbag deployment.

If the seat belt is not worn correctly, it cannot

perform its intended protective function.

WARNING Risk of burns from hot air bag

components

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.

The air bag parts are hot aꢂer an air bag has

been deployed.

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 https://dtsc.ca.gov/. Using the search func-

tion, you will ꢃnd information on perchlorate, for

example.

Do not touch the air bag parts.

Have a deployed air bag replaced at a

qualiꢃed specialist workshop as soon as

possible.

Always ensure that all vehicle occupants

have their seat belts fastened correctly

and are sitting properly.

Mercedes-Benz recommends that you have the

vehicle towed to a qualiꢃed specialist workshop

aꢂer 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:

Always observe the instructions about the correct

driver's seat position and adjusting the seat

(/ page 89).

In order for the correctly worn seat belt to provide

the intended level of protection, each vehicle

occupant must observe the following information:

Seat belts

Protection provided by the 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.

The seat belt must not be twisted and must ꢃt

tightly and snugly across the body.

The bang will not generally aꢀect your hearing.

The seat belt must be routed across the cen-

ter of the shoulder and as low down across

the hips as possible.

In general, the powder released is not hazard-

ous to health but may cause short-term
