belt MERCEDES-BENZ S-CLASS COUPE 2015 Owner's Guide

Always observe the information on suitable
positioning of the child restraint system
(Y page 65) in addition to the child restraint
system manufacturer's installation and oper- ating instructions. Suitable positioning of the child
restraint system
Introduction 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
categories II or 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". Example: approval label on the child restraint
system
"Universal" category child restraint systems
can be used on the seats indicated with U, UF
or IUF according to the tables "Suitability of
the seats for attaching belt-secured child
restraint systems" or "Suitability of the seats
for attaching an ISOFIX child restraint sys-
tem".
Semi-universal child restraint systems are
indicated by the text "semi-universal" on the
approval label. These can be used if the vehi- cle and the seat are listed in the child restraint
system manufacturer's vehicle model list. For
more information, contact the child restraint
system manufacturer or visit their website.
If it is absolutely necessary to fit a child
restraint system to the front-passenger seat:
X Always pay attention to the instructions
under "Child restraint system on the front-
passenger seat" (Y page 63).
There you will find instructions on how to
correctly route the shoulder belt strap from the vehicle seat-belt extender or belt outlet
to the shoulder belt guide on the child
restraint system (Y page 64).
X Move the front-passenger seat as far back
as possible and fully retract the seat cush-
ion length.
If you secure a child in a forward-facing
child restraint system on the front-
passenger seat, also move the front-
passenger seat to the lowest position.
X Move the backrest to an almost vertical
position.
The entire base of the child restraint sys-
tem must always rest on the seat cushion of
the front-passenger seat. The backrest of
the forward-facing child restraint system
must, as far as possible, be resting on the
backrest of the front-passenger seat. The
child restraint system must not touch the
roof or be put under strain by the head
restraint. Adjust the angle of the seat back- rest and the head restraint position accord-
ingly. Also observe the child restraint sys-
tem manufacturer's installation instruc-
tions.
X Move the seat cushion angle to the highest,
most vertical position. Children in the vehicle

Suitability of the seats for attaching belt-secured child restraint systems
If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of
category I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat
does not touch the child restraint system.
Always observe the notes in the "Child restraint system" section (Y page 61) and the child
restraint system manufacturer's installation instructions.
Legend for the table:

Children in the vehicleSafety

R
a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
Detection by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is cov-
ered
R glare on the camera system, e.g. from the
sun being low in the sky
R darkness
R if:
- pedestrians move quickly, e.g. into the
path of the vehicle
- the camera system no longer detects a
pedestrian as a person due to special
clothing or other objects
- a pedestrian is concealed by other
objects
- the typical outline of a person is not dis-
tinguishable from the background
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Following damage to the windscreen, have
the configuration and operation of the cam-
era system checked at a qualified specialist
workshop.
Function X
To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 260).
If the PRE-SAFE ®
Brake is not activated, the
æ symbol appears in the multifunction
display.
This function will issue a warning if:
R at a speed of around 30 km/h or more, the
distance maintained to the vehicle travel-
ling in front is insufficient for several sec-
onds. The
· distance warning lamp then lights
up in the instrument cluster.
R at a speed of around 7 km/h or more, you
rapidly approach a vehicle in front or a
pedestrian.
An intermittent warning tone will then
sound and the ·distance warning lamp
lights up in the instrument cluster.
X Brake immediately to defuse the situation.
or X Take evasive action provided it is safe to do
so.
The PRE-SAFE ®
Brake function can also brake
the vehicle automatically under the following
conditions:
R the driver and front passenger have their
seat belts fastened
and
R the vehicle speed is between approx-
imately 7 km/h and 200 km/h
At a speed of up to approximately 70 km/h,
PRE-SAFE ®
Brake can also detect:
R stationary objects in the path of your vehi-
cle, e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If there is an increased risk of collision,
preventive passenger protection measures
(PRE-SAFE ®
) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Auto- matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
You can prevent the intervention of PRE-
SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal Driving safety systems

WARNING
If children adjust the seats, they could
become trapped, especially if they are unat-
tended. There is a risk of injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle.
The seats can still be adjusted when there is
no key in the ignition lock. G
WARNING
When adjusting a seat, you or another vehicle occupant could become trapped by the guiderail of the seat, for instance. There is a risk of
injury.
Make sure that no one has any part of their
body within the sweep of the seat when
adjusting it.
Observe the safety notes on "Airbags"
(Y page 48) and "Children in the Vehicle"
(Y page 60). G
WARNING
You could lose control of the vehicle while
driving if you:
R adjust the driver's seat, steering wheel or
mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirrors and fasten your seat
belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem. G
WARNING
The head restraints cannot provide the inten-
ded protection unless they are fitted and
adjusted correctly. There is an increased risk of injury to the head and neck in the event of
an accident or sudden braking, for example.

Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off. G

The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder.

WARNING
If the backrest is not engaged, it could fold
forwards during a braking manoeuvre or in the event of an accident, for example. The seat
backrest will then push the vehicle occupant
against the seat belt. The seat belt cannot
protect as intended and could result in addi-
tional injury. This poses an increased risk of
injury.
Before each journey, make sure that the back- rest engages fully as described. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
