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:

R

Fasten seat belts correctly.

The restraint system can no longer function

correctly after alterations have been made.

R

Sit in an almost upright seat position with

their back against the seat backrest.

R

Seat belt system

R

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

R

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

sible.

R

Always secure persons under 5 ft (1.50 m)

tall in an additional restraint system suitable

for Mercedes-Benz vehicles.

R

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

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.

In an accident, the components of the

restraint system may deploy unnecessarily

on the front passenger side if:

R

Before starting your journey, adjust your seat

correctly; the driver's seat and front

passenger seat should be moved as far back

as possible.

When doing so, always observe the informa‐

tion on the correct driver's seat position

(/ page 94).

Only hold the steering wheel by the steering

wheel rim. This allows the airbag to be fully

deployed.

Always lean against the seat backrest when

the vehicle is in motion. Do not lean forwards

or against the door or side window. You may

otherwise be in the deployment area of the

airbags.

If you deviate from the correct seat position,

the airbag cannot perform its intended pro‐

tective function and deployment may even

cause further injuries.

In order to avoid risks, each vehicle occupant

must always make sure of the following:

R

There are heavy objects on the front

passenger seat.

R

The seat belt tongue is engaged in the

seat belt buckle of the front passenger

seat and the front passenger seat is

unoccupied.

R

Fasten seat belts correctly. Pregnant

R

women must take particular care to

ensure that the lap belt never lies across

the abdomen.

#

Stow objects in a suitable place.

#

Only one person should use each seat

belt at any one time.

R

Adopt the correct seat position and keep

as far away as possible from the airbags.

Depending on the detected accident situation,

the window curtain airbag on the front

passenger side may deploy. The airbag is

deployed regardless of whether the front

passenger seat is occupied.

R

Observe the following information.

R

Always keep your feet on the floor. Do not

put your feet on the cockpit, for example.

42 Occupant safety

Your feet may otherwise be in the deploy‐

ment area of the airbag.

If children are traveling in the vehicle,

observe the additional notes (/ page 50).

In addition, no connecting cables, tensioning

straps or retaining straps must be routed or

attached to the vehicle within the deploy‐

ment area of an airbag. Always comply with

the accessory manufacturer's installation

instructions and, in particular, the notes on

suitable places for installation.

There are no heavy, sharp-edged or fragile

objects in the pockets of your clothing. Store

such objects in a suitable place.

&

WARNING Risk of injury or death due to

the use of unsuitable seat covers

R

Unsuitable seat covers can obstruct or pre‐

vent the deployment of air bags integrated

into the seats.

Consequently, the air bags cannot protect

vehicle occupants as they are designed to

do. In addition, operation of the automatic

front passenger air bag shutoff may be

restricted.

R

Always stow and secure objects correctly.

Objects in the vehicle interior may prevent an

airbag from functioning correctly. Each vehicle

occupant must always make sure of the follow‐

ing in particular:

R

There are no people, animals or objects

between the vehicle occupants and an air‐

bag.

There are no objects between the seat, door

and door pillar (B-pillar).

There are no hard objects, e.g. coat hangers,

hanging on the grab handles or coat hooks.

There are no accessory parts, such as mobile

navigation devices, mobile phones or cup

holders, attached to the vehicle within the

deployment area of an airbag, e.g. on the

cockpit, on the door, on the side window or

on the side wall trim.

Observing laws and legal requirements

Always observe the legal requirements when

using a child restraint system in the vehicle.

R

The vehicle seat must be suitable for instal‐

ling a child restraint system.

Safely transporting children in the vehicle

Always observe when children are traveling

in the vehicle

Accident statistics show that children secured

on the rear seats are generally safer than chil‐

dren secured on the front seats. For this reason,

Mercedes-Benz strongly advises that you install

a child restraint system on a rear seat.

Observing standards for child restraint sys‐

tems

All child restraint systems must meet the follow‐

ing standards:

Securing systems for child restraint systems

in the vehicle

Only use the following securing systems for child

restraint systems:

&

WARNING Risk of injury or death caused

by incorrect installation of the child

restraint system

Advantage of a rearward-facing child

restraint system

It is preferable to transport a baby or a small

child in a suitable rearward-facing child restraint

system. In this case, the child sits in the oppo‐

site direction to the direction of travel and faces

backwards.

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.

R

the LATCH-type (ISOFIX) mounting brackets

If the child restraint system is incorrectly

installed on a suitable seating position, it

cannot perform its intended protective func‐

tion.

The child cannot be restrained in the event of

an accident, heavy braking or a sudden

change of direction.

R

R

the Top Tether anchorages

Installing a LATCH-type (ISOFIX) child restraint

system is preferred.

Simply attaching to the securing rings on the

vehicle 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 sys‐

tem (/ page 56).

A booster seat may be necessary to achieve

proper seat belt positioning for children over

The child restraint system may no longer

function as it is supposed to if you make

modifications or attach objects to it, e.g. toys

or unsuitable accessories. This poses an

increased risk of injury!

Never modify the child restraint system. Only

attach accessories which the manufacturer

of the child restraint system has authorized

especially for this child restraint system.

-

Secure the child restraint system with the

seat belt on the rear seat (/ page 59).
