G
WARNING
If you connect equipment to the diagnostics
connection, it can affect the operation of the
vehicle systems. This can impair the operating
safety of your vehicle while driving. There is a
risk of accident.
Do not connect any equipment to the
diagnostics connection. G
WARNING
Loose equipment or equipment cables that
are connected to the diagnostics connection
can obstruct the area around the pedals. The
equipment or the cables could get between
the pedals in the event of sudden braking or
acceleration. As a result, the movement of the
pedals may be impaired. There is a risk of
accident. Do not attach any equipment or cables in the
driver footwell.
! If the engine is switched off and
equipment on the diagnostics connection
is used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can, for example, lead to
emissions monitoring information being
reset. This may lead to the vehicle failing to
meet the requirements of the next emissions
test during the main inspection. Qualified specialist workshop
An authorized Mercedes-Ben zCenter is a
qualified specialist workshop. It has the
necessary specialist knowledge, tools and
qualifications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.
Observe the notes in the Maintenance
Booklet.
Always have the following work carried out at
an authorized Mercedes-BenzC enter:
R work relevant to safety
R service and maintenance work
R repair work
R alterations, installation work and
modifications
R work on electronic components Correct use
G
WARNING
There are various warning stickers affixed to
your vehicle. Their purpose is to alert you and
others to various dangers. Therefore, do not
remove any warning stickers unless the
sticker clearly states that you may do so. Introduction
29 Z
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have bee napproved by
Mercedes-Benz.
Both the driver and the passenger should
always use the 42 indicator
lamp as an indication of whether or not the
passenger is properly positioned. G
WARNING
If the 42 indicator lamp lights up
when an adult or someone larger than a small
individual is in the front-passenger seat, have
the fron tpassenger reposition himself or
herself in the seat until the 42
indicator lamp goes out.
In the event of a collision, the air bag control
unit will no tallow front-passenge rfront air
bag deployment when the OCS has classified
the front-passenge rseat occupant as
weighing as much as or less than a typical 12-
month-old child in a standard child restraint
or if the front-passenger seat is classified as
being empty.
When the OCS senses that the front-
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 42 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front-
passenger fron tair bag is deactivated.
When the OCS senses that the front-
passenger seat is classified as being empty,
the 42 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicatin gthat the front-
passenger front air bag is deactivated.
When the OCS senses that the front-
passenger seat occupant is classified as
being heavier than the weight of a typical 12-
month-old child seated in astandard child
restraint or as being a small individual (such
as a young teenager or asmall adult), the
42 indicator lamp will illuminate
for approximately 6seconds when the engine
is started and then, depending on occupant weight sensor readings from the front-
passenger seat, remain illuminated or go out.
With the
42 indicator lamp
illuminated, the front-passenger fron tair bag
is deactivated. With the 42
indicator lamp out, the front-passenger front
air bag is activated.
When the OCS senses that the front-
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 42 indicator lamp
will illuminate for approximately 6seconds
when the engine is started and then go out,
indicating that the front-passenger front air
bag is activated.
If the 42 indicator lamp is
illuminated, the front-passenger fron tair bag
is deactivated and will not be deployed.
If the 42 indicator lamp is not
illuminated, the front-passenge rfront air bag
is activated and will be deployed:
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the side impact air bags
If the front-passenger front air bag is
deployed, the rate of inflation will be
influenced by:
R the rate of vehicle deceleratio nas assessed
by the air bag control unit
R the front passenger's weight category as
identified by OCS
For further information, see "Air bag display
messages" (Y page 364). G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat Occupant safety
51Safety
Z
PRE-SAFE
®
(anticipatory occupant
protection system) G
WARNING
The PRE-SAFE ®
system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
PRE-SAFE ®
takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R if BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation
detected:
R the front-passenger seat is adjusted if it is
in an unfavorable position.
R the air pressure in the side bolsters of the
seat cushion and seat backrest of the front
active multicontour seats is increased.
R if the vehicle skids, the side windows and
sliding sunroof are closed so that only a
small gap remains.
If the hazardous situation passes without
resulting in an accident:
R the air pressure in the side bolsters of the
active multicontour seat is reduced again.
R all settings made by PRE-SAFE ®
can then
be reversed. If the seat belts are not released:
X
Move the backrest back slightly, but only
when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released. G
WARNING
Make sure that nobody can become trapped
as you adjust the seat.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged. Seat belts
Important safety notes The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadianp
rovinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.
i For further information on infants and
children traveling in the vehicle and on
infant and child restraint systems, see
"Children in the vehicle" (Y page 59). G
WARNING
Always fasten yours eat belt before driving off.
Always make sure all of your passengers are
properly restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
seat belt properly buckled. Without your seat
belt buckled, you are much more likely to hit
the interior of the vehicle or be ejected from
it. You can be seriously injured or killed. Occupant safety
