If yourv
ehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Vehicles without automatic child seat recog-
nition on the front-passenger seat: when you
turn the key to position 2inthe ignition lock,
the 4 PASSENGER AIRBAG OFF indicator
lamp lights up briefly, but does not have any
function. It does not indicate that there is
automatic child seat recognition on the front-
passenger seat. The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Ben zchild seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case, 4
PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger front airbag is
disabled. i
If the front-passenger front airbag is dis-
abled by the automatic child seat recogni-
tion, the following remain enabled on the
front-passenger side:

ISOFIX child seat securing system for
the rear seats G
WARNING
Ac hild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
a child restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system with the vehicle seat belt as well. In
addition, when fitting a child restraint system,
be sure to observe the manufacturer's instal-
lation instructions and the instructions for
correct use of the child restraint system. G
WARNING
Please note that if child restraint systems, or
their retaining systems, are damaged or sub-
jected to a load in an accident, they may not
be able to provide their protective function.
This could result in serious or even fatal inju-
ries to the secured child in the event of an
accident, heavy braking or a sudden change
in direction.
For this reason, have child restraint systems
and their anchorages which have been dam-
aged or subjected to a load in an accident
checked immediately at a qualified specialist
workshop. Children in the vehicle

Install the ISOFIX child restraint system.
Comply with the manufacturer's instruc-
tions when installing the ISOFIX child
restraint system.
ISOFIX is a standardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of the rear seats.
Mercedes-Benz recommends the use of ISO-
FIX child restraint systems listed together
with the insertion guides included
(Y page 62). Using insertion guides makes
it easier to fit ISOFIX child restraint systems. Top Tether Top Tether anchorages
The Coupé has Top Tether anchorages.
Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the rear seat. It helps reduce
the risk of injury even further.
The Top Tether anchorage points are located
in the rear compartment behind the head
restraints.

ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort .Inaddi-

also has the HOLD functio n(Ypage 198 )and
hill start assist (Y page 162). PRE-SAFE
®
Brake
i Observe the "Important safety notes" sec-
tion (Y page 64).
PRE-SAFE ®
Brake is only available in vehicles
with DISTRONIC PLUS.
PRE-SAFE ®
Brake can help you to minimise
the ris kofacollisio nwith a vehicle ahead or
reduce the effects of such a collision. If PRE-
SAFE ®
Brake detects a risk of collision, you
will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®
Brake cannot prevent a collision without your
intervention.
This function will issue a warning if:
R at speeds of around 30 km/h or more, over
several seconds, the distanc emaintained
to the vehicle travelling in front is insuffi-
cient.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7km/h or
higher, you very quickly approach a vehicle
in front.
An intermittent warning tone will then
sound and the ·distance warning lamp
will light up in the instrument cluster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
From a speed of approximately 7km/h, if the
driver and passengers have fastened their
seat belts, PRE-SAFE ®
Brake can brake the vehicle automatically at speeds up to approx-
imatel
y200 km/h.
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake.
You can prevent the intervention of the PRE-
SAFE ®
Brake at any time by:
R depressing the accelerato rpedal further
R activating kickdown
R releasing the brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle.
R there is no longer any danger of a rear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds up to approximately 70 km/h, PRE-
SAFE ®
Brake can also detect stationary
obstacles such as stopped or parked vehi-
cles.
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventative passenger protec-
tion measures (PRE-SAFE ®
) are activated
(Y page 48). If, at speeds over 30 km/h, a risk
of collision remains and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided. Driving safet

vehicle with the soft top down.
You can open or close AIRCAP either when
the vehicle is stationary or when driving up to
a speed of 160 km/h.
AIRCAP has the following components:

Important safety notes
G
WARNING
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could adjust the seats and
become trapped. G
WARNING
Only adjust the driver's seat when the vehicle
is stationary. You will otherwise be distracted
from the road and traffic conditions and you
could lose control of the vehicle as a result of
the seat moving. This could cause an acci-
dent. G
WARNING
If you adjust the seat height carelessly, you or
others could be trapped and thereby injured.
Children in particular could unintentionally
press the buttons to electrically adjust the
seats and become trapped.
Take care that:
R while moving the seats, your hands do not
get under the lever assembly of the seat
adjustment system.
R children in the vehicle do not slide their
hands under the levers. G
WARNING
Make sure that nobody can become trapped
when adjusting the seats.
Observe the notes on airbags.
Secure children as recommended; see the
"Children in the vehicle" section. G
WARNING
Make sure that the back of your head is sup-
ported at eye level by the central area of the head restraint. If your head is not supported
correctly by the head restraint, you could suf-
fer a severe neck injury in the event of an
accident. Never drive if the head restraints are
not engaged and set correctly.
G
WARNING
As eat belt can only offer its intended degree
of protection when the backrest is almost ver-
tical and the occupant is sitting upright. Avoid
seat positions that do not allow the seat belt
to be routed correctly. Adjust the backrest so
that it is as upright as possible. Never travel
with the backrest reclined too far backwards.
You could otherwise be seriously or even
fatally injured in the event of an accident or
sudden braking.
! To avoid damage to the seats and the seat
heating, observe the following information:
R do not spill any liquids on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov-
ers, child seats or booster seats.
