Storing the padded table and the side
head restraints G
WARNING
Secure the ICS padded play table and the side
head restraints in the vehicle as specified; otherwise, they may come loose. In the event
of an accident, sudden braking or abrupt
change in direction, they could injure vehicle
occupants or cause damage to the vehicle.
When you are not using the ICS padded play
table and the side head restraints, store these
in a suitable place, such as the boot.
For example, on vehicles with TIREFIT, you
can store the side head restraints in the stow-
age compartment under the boot/luggage
compartment floor (Y page 305)/
(Y page 305). 64

Vehicles with a folding bench seat in the load compartment (Estate): information on child
restraint systems on the folding bench seat can be obtained at any Mercedes-Ben zService
Centre.
"Universal" category child restraint systems can be recognised by their orange approval label.
3 Vehicles with automatic child seat recognition on the front-passenger seat: a child restraint system of the
"Universal" category with a transponder for automatic child seat recognition must be fitted. The 4
PASSENGER AIRBAG OFF indicator lamp must be lit.

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/ho rmore, over
several seconds, the distance maintained
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 from a speed of up to
approximatel 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. To end this,
you can eithe rdepress the accelerator pedal
further, activate kickdown or release 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, for example, stopped or parked
vehicles.
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will initially alert you both visually and acous-
tically. If you do not brake or take evasive
action, the system will warn you by automat-
ically braking the vehicle gently. If there is an
increased risk of collision, preventative
passenger protection 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 signifi-
cantly accelerate, automatic braking may be
performed up to a level of automatic emer-
gency braking. Automatic emergency braking
is not performed until immediately prior to an
acciden tthat can no longer be avoided. G
WARNING
Even if PRE-SAFE ®
Brake slows the vehicle
before an imminent rear-end collision, the
system cannot avert a collision without the
intervention of the driver. There is a risk of an
accident. Brake according to the situation or
take evasive action. Delayed intervention by
the driver can lead to an accident. G
WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident. Always pay par-
ticular attention to the traffic situation and be
ready to brake, especially if PRE-SAFE ®
Brake
warns you. Terminate the intervention in a
non-critical driving situation. 76

X
Immediately pull the corresponding switch
on the door control panel until the side win-
dow is completely closed (Y page 96).

WARNING
Closing the side windows with increased force
or without the anti-entrapment feature could
lead to serious or even fatal injury. Make sure
that nobody can become trapped when clos-
ing the side windows.
If a side window is obstructed during closing
and reopens again slightly:

Important safety notes
Your vehicle may be fitted with a sliding sun-
roof or a panorama sliding sunroof. In the fol-
lowing section, the term "sliding sunroof"
refers to both types of sliding sunroof. G
WARNING
Make sure that nobody can become trapped
when opening and closing the sliding sunroof.
If there is a risk of entrapment, release the
switch immediately. During automatic opera-
tion, push the switch briefly in any direction
to stop the sliding sunroof. G
WARNING
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
WARNING
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.
! Only open the panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window slightly to reduce or
eliminate these noises. 98

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
adjustmen tsystem.
R children in the vehicle do no tslide 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 .Ifyour 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- Seats
