R
vehicles with the memory function: the
front-passenger seat is adjusted if it is in an unfavourable position.
R Vehicles with a multicontour seat or active
multicontour seat: the air pressure in the
side bolsters of the backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. On vehicles with mul-
ticontour seats/active multicontour seats,
the air pressure in the side bolsters is reduced
again. All settings made by PRE-SAFE ®
can
then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Fur-
ther information can be found under "Belt
adjustment" (Y page 47). Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R the electrically adjustable steering wheel is
raised
R the engine is switched off
R vehicles with the Mercedes-Benz emer-
gency call system: automatic emergency
call Children in the vehicle
Important safety 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. Children are generally better pro-
tected there.
If a child younger than 12 years old and under
1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child.
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
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. Children in the vehicle

Move the belt height adjustment to the low-
est position.
X Move the backrest to an almost vertical
position.
The bottom and back of a forward-facing
child restraint system must make full con-
tact with the front-passenger seat cushion
and backrest. The child restraint system
must not touch the roof. Adjust the back-
rest angle accordingly. Also observe the
child restraint system manufacturer's
installation instructions.
"Universal" category child restraint systems
can be recognised by their orange approval
label and the text "Universal". Example: approval label on the child restraint sys-
tem
"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 belted child restraint
systems" or "Suitability of the seats for
attaching an ISOFIX child restraint system".
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. Suitability of the seats for attaching bel-

Important safety notes
G
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. 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
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. 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.
Always drive with the head restraints fitted.
Ensure that the centre of the head restraints
support the back of each vehicle occupant's
head at eye level before driving off. 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-
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. Seats

!
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 "Interior care".
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.
! Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam- aged.
i The head restraints in the front seats are
fitted with the NECK-PRO system
(Y page 53). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
For more information, contact a qualified
specialist workshop.
