Occupant safety 33

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 by the restraint system

WARNING Risk of injury or death from

modifications to the restraint system

The restraint system includes the following com‐

ponents:

Fasten seat belts correctly.

The restraint system can no longer function

correctly after alterations have been made.

Sit in an almost upright seat position with

their back against the seat backrest.

Seat belt system

Airbags

Child restraint system

Child seat securing systems

The restraint system may then not protect

the vehicle occupants as intended by failing

in an accident or triggering unexpectedly, for

example

Sit with their feet resting on the floor, if pos‐

sible.

Always secure persons under 5 ft (1.50 m)

tall in an additional restraint system suitable

for Mercedes-Benz vehicles.

The restraint system can help prevent the vehi‐

cle 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 occupants 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 offered by a correctly worn seat belt.

Emergency Tensioning Devices and/or airbags

are not deployed in every accident.

Never alter the parts of the restraint

system.

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.

Never tamper with the wiring or any

electronic component parts or their

software.

If it is necessary to modify the vehicle to accom‐

modate a person with disabilities, contact an

authorized Mercedes-Benz Center for details.

Assistance Center on 1-800-FOR-MERCedes

Restraint system functionality

the components of the restraint system must

take place in good time at the start of the colli‐

Factors which can only be seen and measured

after a collision has occurred do not play a deci‐

they provide an indication of airbag deployment.

gered unintentionally or may not deploy as

intended during an accident. This may affect

the Emergency Tensioning Devices or air‐

bags, for example.

When the ignition is switched on, a self-test is

performed, during which the 6 restraint sys‐

tem warning lamp lights up. It goes out no later

than a few seconds after the vehicle is started.

The components of the restraint system are then

functional.

Have the restraint system checked and

repaired immediately at a qualified spe‐

cialist workshop.

The vehicle may be deformed significantly with‐

out an airbag being deployed. This is the case if

only parts which are relatively easily deformed

are affected and the rate of vehicle deceleration

is not high. Conversely, an airbag may be

deployed even though the vehicle suffers only

minor deformation. If very rigid vehicle parts

such as longitudinal members are hit, for exam‐

ple, this may result in sufficiently high levels of

vehicle deceleration.

Function of the restraint system in an acci‐

A malfunction has occurred in the restraint sys‐

How the restraint system works is determined by

the severity of the impact detected and the type

of accident anticipated:

switched on

lights up continuously or repeatedly during a

Side impact

WARNING Risk of injury due to malfunc‐

tions in the restraint system

The activation thresholds for the components of

the restraint system are determined based on

the evaluation of the sensor values measured at

various points in the vehicle. This process is pre-

emptive in nature. The triggering/deployment of

Mercedes-Benz recommends that you have the

vehicle towed to a qualified specialist workshop

after an accident. Take this into account, partic‐

ularly if an Emergency Tensioning Device is trig‐

gered or an airbag deployed.

If the Emergency Tensioning Devices are trig‐
