Information on the child restraint system

When tting a child restraint system, observe the

notes in "Children in the vehicle" (/ page 126).

Notes on the child restraint system on the front

passenger seat

WARNING Risk of injury or death due to

an enabled co-driver airbag

If the co-driver airbag is enabled, a child on

the co-driver seat may be struck by the co-

driver airbag during an accident.

NEVER use a rearward-facing child

restraint system on a seat with an ENA-

BLED FRONT AIRBAG. DEATH or SERI-

OUS INJURY to the CHILD can occur.

Also pay particular attention to the notes on rear-

ward-facing or forward-facing child restraint sys-

tems on the front passenger seat (/ page 131).

Information on the automatic functions of the

restraint system

Function of the automatic front passenger airbag

shuto

A person on the front passenger seat must

observe the following information:

Sit correctly (/ page 110).

Fasten the seat belt correctly (/ page 111).

The automatic front passenger airbag shuto can

disable or enable the front passenger airbag

according to the situation.

Make sure you observe the following information:

The status of the front passenger airbag, see

"Function of the PASSENGER AIR BAG indica-

tor lamps"(/ page 114).

When tting a child restraint system to the

front passenger seat, observe the vehicle-spe-

cic information (/ page 131).

Status of the front passenger airbag in relation to

the stature of the person:

Front passenger airbag disabled: PASSENGER

AIR BAG OFF lights up continuously.

The front passenger airbag will not be

deployed in the event of an accident. If

PASSENGER AIR BAG OFF is lit, no one may

use the front passenger seat.

Occupant safety – Information on the automatic functions of the restraint system

F167 0057 02

Front passenger airbag enabled: PASSENGER

AIR BAG ON lights up for up to 60 seconds or

until both the PASSENGER AIR BAG ON and

OFF indicator lamps go out.

The front passenger airbag may be deployed

during an accident. Observe the following

information on the correct seat position

(/ page 110).

Vehicles with rear seats: a person of smaller

stature should use a rear seat.

System limits

The front passenger airbag may otherwise be dis-

abled by mistake, for example, in the following sit-

uation:

The front passenger transfers their weight by

supporting themselves on a vehicle armrest.

The front passenger sits in such a way that

their weight is raised from the seat surface.

NOTE Deployment of components of the

restraint system when the front passenger

seat is unoccupied

In an accident, the components of the

restraint system may deploy unnecessarily on

the front passenger side if:

There are heavy objects on the front

passenger seat.

The seat belt tongue is engaged in the seat

belt buckle of the front passenger seat and

the front passenger seat is unoccupied.

Stow objects in a suitable place.

Only one person should use each seat

belt at any one time.

Depending on the detected accident situation, the

window airbag on the front passenger side may

deploy. The airbag is deployed regardless of

whether the front passenger seat is occupied.

Function of PRE-SAFE

(anticipatory occupant

protection)

PRE-SAFE

is able to detect certain critical driv-

ing situations and implement pre-emptive meas-

ures to protect the vehicle occupants.

PRE-SAFE

can implement the following meas-

ures independently of each other:

Tightening the seat belts on the driver's seat

and front passenger seat.

Closing the side windows.

Vehicles with sliding sunroof: closing the slid-

ing sunroof.

Vehicles with memory function: moving the

front passenger seat to a more favourable seat

position.

Vehicles with multicontour seat: increasing the

lateral support by inating the seat side bol-

sters of the seat backrest.

PRE-SAFE

Sound: provided that the multime-

dia system is switched on, generating a brief

noise signal to stimulate the innate protective

mechanism of a person's hearing.

NOTE Damage caused by objects in the

footwell or behind the seat

The automatic adjustment of the seat position

may result in damage to the seat and/or the

object.

Stow objects in a suitable place.

Reversing the PRE-SAFE

system measures

If an accident did not occur, the pre-emptive

measures that were taken are reversed.

You will need to perform certain settings yourself.

If the seat belt pre-tensioning is not reduced,

move the seat backrest slightly backwards.

The seat belt pre-tensioning releases.

Function of PRE-SAFE

PLUS (anticipatory occu-

pant protection plus)

PRE-SAFE

PLUS can detect certain impacts, par-

ticularly an imminent rear impact, and take pre-

emptive measures to protect the vehicle occu-

pants. These measures cannot necessarily pre-

vent an imminent impact.

PRE-SAFE

PLUS can implement the following

measures independently of each other:

Tightening the seat belts on the driver's seat

and front passenger seat.

Activating the rear hazard warning lights at a

higher ashing frequency.

Increasing brake pressure when the vehicle is

stationary. This brake application is cancelled

automatically when the vehicle pulls away.

If an accident did not occur, the pre-emptive

measures that were taken are reversed.

System limits

The system will not initiate any action in the fol-

lowing situations:

when reversing

when the vehicle is towing a trailer and there

is a risk of a rear impact

The system will not initiate any brake application

in the following situations:

whilst driving

when entering or exiting a parking space while

using Active Parking Assist

Function of PRE-SAFE

Impulse Side

If an imminent side impact is detected, PRE-

SAFE

Impulse Side can pre-emptively move the

front seat vehicle occupant's upper body towards

the centre of the vehicle. It does this by rapidly

inating an air cushion in the outer seat side bol-

ster of the seat backrest on the side on which the

impact is anticipated. This increases the distance

between the door and the vehicle occupant.

If PRE-SAFE

Impulse Side has been deployed or

is faulty, the

PRE-SAFE impulse side inoperative

Seat belt adjustment function

Vehicles with PRE-SAFE

: aer you have fastened

the seat belt of the front seat, it may adjust itself

against your body by pulling at the shoulder until

somewhat tight. Do not hold the seat belt tightly

while it is adjusting.

This function is a reminder that all vehicle occu-

pants must wear their seat belts correctly.

You can activate and deactivate the seat belt

adjustment function using the multimedia system

(/ page 119).

Overview of the automatic measures aer an acci-

dent

Depending on the type and severity of the acci-

dent, and depending on the vehicle's equipment,

the following measures can be implemented, for

example:

automatic braking (post-collision brake)

(/ page 119)

activating the hazard warning lights

triggering an automatic emergency call

(/ page 69)

switching o the engine

To start the vehicle again, switch the vehicle

o and on once more (/ page 273). Depend-

ing on the type and severity of the accident,

you may no longer be able to start the vehicle.

switching o the fuel supply

Plug-in hybrid: switching o the hybrid system

and high-voltage on-board electrical system

unlocking the vehicle doors

lowering the side windows

displaying the emergency guide in the central

display (/ page 70)

switching on the interior lighting

Function of the post-collision brake aer an acci-

dent

Depending on the accident situation, the post-col-

lision brake can minimise the severity of a further

collision or even avoid it.

If an accident is detected, the post-collision brake

can initiate automatic braking. When the vehicle

has come to a standstill, the electric parking

brake is automatically applied.

The driver can cancel automatic braking by taking

the following actions:

braking more strongly than automatic braking

fully depressing the accelerator pedal with

force
