Based on the evaluation of this data, the

restraint system control unit triggers the seat

belt tensioners in the event of a head-on or

rear collision.

WARNING

G

Pyrotechnic seat belt tensioners that have

been deployed are no longer operational and

are unable to perform their intended protec-

tive function. This poses an increased risk of

injury or even fatal injury.

Therefore, have pyrotechnic belt tensioners

which have been triggered immediately

replaced at a qualified specialist workshop.

A seat belt tensioner can only be triggered if:

R

the ignition is switched on

R

the components of the restraint system are

operational. You can find further informa-

tion under: "Restraint system warning

lamp" (Y page 41)

R

the belt tongue has engaged in the belt

Mercedes-Benz recommends that you have

the vehicle towed to a qualified specialist

workshop after an accident. Take this into

account, particularly if a seat belt tensioner

was triggered or an airbag was deployed.

An electric motor is used by PRE-SAFE^®to

trigger the tightening of the seat belt in haz-

ardous situations. This procedure is reversi-

ble.

If the belt tensioners are triggered or an air-

bag is deployed, you will hear a bang, and a

small amount of powder may also be

released. The 6 restraint system warning

lamp lights up.

Only in rare cases will the bang affect your

hearing. In general, the powder released is

not hazardous to health but may cause short-

term breathing difficulties to persons suffer-

ing from asthma or other pulmonary condi-

tions. Provided it is safe to do so, you should

leave the vehicle immediately or open the

window in order to prevent breathing difficul-

ties.

The seat belt tensioners in the rear compart-

ment are triggered independently of the lock

status of the seat belts.

If the restraint system control unit detects a

high severity accident, in certain head-on col-

lisions, additional components of the

restraint system are deployed independently

of each other:

front airbags and driver's kneebag

On vehicles with the automatic front-

passenger front airbag deactivation system:

depending on the person in the front-

passenger seat, the front-passenger front air-

bag is either disabled or enabled. The front-

passenger front airbag can only be deployed

in an accident if the PASSENGER AIR BAG ON

indicator lamp is lit. Observe the information

on the PASSENGER AIR BAG indicator lamps

i Not all airbags are deployed in an acci-

dent. The different airbag systems work

independently of each other.

How the airbag system works is deter-

mined by the severity of the accident detec-

ted, especially the vehicle deceleration or

acceleration, and the apparent type of acci-

dent:

R

the distribution of forces during the colli-

sion

R

the collision angle

R

R

the characteristics of the object with which

the vehicle has collided

Factors whichcan only be seen and measured

after a collision has occurred do not play a

decisive role in the deployment of an airbag,

nor do they provide an indication of airbag

deployment.

The vehicle may be deformed significantly

without an airbag being deployed. This is the

case if only parts which are relatively easily

deformed are affected and the rate of decel-

eration is not high. Conversely, an airbag may

be deployed even though the vehicle suffers

only minor deformation. This is the case if, for

example, very rigid vehicle parts such as lon-

gitudinal body members are hit, and sufficient

deceleration occurs as a result.

Introduction

In certain hazardous situations, PRE-SAFE^®

takes pre-emptive measures to protect the

vehicle occupants.

Important safety notes

! Make sure that there are no objects in the

footwell or behind the seats. There is a risk

that the seats and/or the objects could be

damaged when PRE-SAFE^®is activated.

If the restraint system control unit detects a

side impact, the applicable components of

the restraint system are activated independ-

ently of each other.

Although your vehicle is equipped with PRE-

SAFE^®, the possibility of injury in the event of

an accident cannot be ruled out. Always

WARNING

G

If the child restraint system is incorrectly fit-

ted on the seat position suitable for this pur-

pose, it cannot perform its intended protec-

tive function. In the event of an accident,

sharp braking or a sudden change in direction,

the child may not be held securely. There is an

increased risk of serious or even fatal injuries.

Observe the manufacturer's installation

instructions and the correct use for the child

restraint system. Make sure that the entire

surface of the child restraint system is resting

on the seat surface. Never place objects

under or behind the child restraint system,

e.g. cushions. Only use child restraint sys-

tems with the original cover designed for

them. Only replace damaged covers with gen-

uine covers.

WARNING

G

If persons (particularly children) are exposed

to heat or cold for a prolonged period, there is

a risk of serious or even fatal injuries. Never

leave persons (particularly children) unatten-

ded in the vehicle.

WARNING

G

If the child restraint system is placed in direct

sunlight, the parts could become very hot.

Children could be suffer burns by touching

these parts, in particular on the metallic parts

of the child restraint system. There is a risk of

injury.

WARNING

G

If you and your child leave the vehicle, always

make sure that the child restraint system is

not in direct sunlight. Cover it with a blanket,

for example. If the child restraint system has

been exposed to direct sunlight, leave it to

cool down before securing the child in it.

Never leave children unattended in the vehi-

cle.

If the child restraint system is fitted incor-

rectly or is not secured, it can come loose in

the event of an accident, heavy braking or a

sudden change in direction. The child

restraint system could be thrown about, strik-

ing vehicle occupants. There is an increased

risk of injury, possibly even fatal.

Always fit child restraint systems properly,

even if they are not being used. Make sure

that you observe the child restraint system

manufacturer's installation instructions.

Always ensure that all vehicle occupants have

their seat belts fastened correctly and are sit-

ting properly. Particular attention must be

paid to children.

Observe the safety notes on the seat belt

(Y page 42) and the information on the cor-

rect use of the seat belt (Y page 44).

WARNING

If the child weighs more than 22 kg, only use

ISOFIX child restraint systems with which the

child is also secured with the vehicle seat belt.

Also secure the child restraint system with the

Top Tether belt, if available.

G

Child restraint systems or their securing sys-

tems that have been damaged or subjected to

a load in an accident cannot perform their

intended protective function. In the event of

an accident, sharp braking or a sudden

change in direction, the child may not be held

securely. There is an increased risk of serious

or even fatal injuries.

Immediately replace child restraint systems

that have been damaged or subjected to a

load in an accident. Have the child restraint

securing systems checked in a qualified spe-

cialist workshop before fitting a child restraint

system again.

When fitting a child restraint system, be sure

to observe the manufacturer's installation

and operating instructions and the instruc-

tions for correct use of the child restraint sys-

tem (Y page 62).

Before every trip, make sure that the ISOFIX

child restraint system is engaged correctly in

both ISOFIX securing rings.

Top Tether

Introduction

Top Tether provides an additional connection

between the child restraint system secured

with ISOFIX and the vehicle. It helps reduce

the risk of injury even further. If the child

restraint system is fitted with a Top Tether

belt, this should always be used.

Important safety notes

General notes

Accident statistics show that children

secured in the rear seats are safer than chil-

dren secured in the front-passenger seat. For

this reason, Mercedes-Benz strongly advises

that you install a child restraint system on a

rear seat.

Vehicles with the automatic front-passenger

front airbag deactivation system: if it is abso-

lutely necessary to fit a child restraint system

to the front-passenger seat, always observe

the information on the "Automatic front-

passenger front airbag deactivation system"

(Y page 49).

In this case, always ensure that the co-driver's

airbag is disabled. The PASSENGER AIRBAG

OFF indicator lamp must light up.

NEVER use a rearward facing child restraint

on a seat protected by an ACTIVE AIRBAG in

front of it; DEATH or SERIOUS INJURY to the

CHILD can occur.

If the PASSENGER AIR BAG ON indicator lamp

is lit, the front-passenger front airbag is ena-

bled (Y page 41).

Vehicles without the automatic front-

passenger front airbag deactivation

system

You can thus avoid the risks that could arise

as a result of:

R

a child restraint system that is not detected

by the automatic front-passenger front air-

bag deactivation system

R

the unintentional disabling of the front-

passenger front airbag

R

the unsuitable positioning of the child

restraint system, e.g. too close to the dash-

board

If the front-passenger seat of your vehicle is

not equipped with the automatic front-

Rearward-facing child restraint system

Introduction

If it is absolutely necessary to fit a rearward-

facing child restraint system to the front-

passenger seat, always make sure that the

front-passenger front airbag is disabled. Only

if the PASSENGER AIR BAG OFF indicator

lamp is lit continuously (Y page 41)is the

front-passenger front airbag disabled.

Always observe the information on suitable

positioning of the child restraint system

(Y page 62) in addition to the child restraint

system manufacturer's installation and oper-

ating instructions.

Only child restraint systems which are

approved in accordance with the ECE stand-

ard ECE R44 are permitted for use in the vehi-

cle.

For certain child restraint systems in weight

category III, this can mean that the area of use

is restricted. The maximum size setting of the

child restraint system is not possible due to

possible contact with the roof.

"Universal" category child restraint systems

can be recognised by their orange approval

label and the text "Universal".

Forward-facing child restraint system

If it is absolutely necessary to fit a forward-

facing child restraint system to the front-

passenger seat, always move the front-

passenger seat as far back as possible. Fully

retract the seat cushion length. The entire

base of the child restraint system must

always rest on the seat cushion of the front-

passenger seat. The backrest of the child

restraint system must, as far as possible, lie

flat against the backrest of the front-

passenger seat. The child restraint system

must not touch the roof or be put under strain
