2013 MERCEDES-BENZ SL-CLASS ROADSTER reset

When deployed, side impact air bags
: offer
additional protection for the thorax of the
vehicle occupants on the side of the vehicle
on which the impact occurs. However, they
do not protect the:
R head
R neck
R arms
side impact air bags :
are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R depending on whether the seat belt is being
used
R independently of the front air bags
R independently of the ETDs
If the vehicle rolls over, side impact air
bags : are generally not deployed. side
impact air bags : are deployed if the system
detects high vehicle deceleration or
acceleration in a lateral direction and
determines that side impact air bag
deployment can offer additional protection to
that provided by the seat belt.
side impact air bags : will not deploy in side
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
If OCS detects that the front-passenger seat
is not occupied and the front-passenger seat
belt is not fastened, side impact air bag : on
the front-passenger side will not deploy. side
impact air bag : on the front-passenger side
will deploy if the front-passenger seat belt is
fastened, regardless of whether the front-
passenger seat is occupied or not. Head bags
Example: head bag on the front-passenger side
Head
bags :

enhance the level of protection
for the head, but not chest or arms, of the
vehicle occupants on the side of the vehicle
on which the impact occurs.
Head bags : deploy in the area of the side
windows at the front. They are deployed:
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R on the side on which an impact occurs
R on the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that air bag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
R independently of the use of the seat belt
R independently of the front air bags
Head bags : will not deploy in side impacts
which do not exceed the system's preset
deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
If OCS detects that the front-passenger seat
is not occupied and the front-passenger seat
belt is not fastened, head bag : on the front-
passenger side will not deploy. Head bag :
on the front-passenger side will deploy if the
front-passenger seat belt is fastened,
regardless of whether the front-passenger
seat is occupied or not. 42

(preventative occupant
protection) G
WARNING
Make sure that nobody can become trapped
as you adjust the seat. 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.
! 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.
PRE-SAFE ®
takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R if BAS intervenes, e.g. in emergency
braking situations
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS.
R when the radar sensor system detects an
imminent danger of collision in certain
situations 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 seat belts are pre-tensioned.
R the front-passenger seat is adjusted if it is
in an unfavorable position.
R vehicles with a multicontour seat or active
multicontour seat: the air pressure in the side bolsters of the seat cushion and
backrest is increased.
R if the vehicle skids, the side windows are
closed almost completely.
If the hazardous situation passes without
resulting in

an accident, PRE-SAFE ®
slackens
the belt pretensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released.

Introduction G
WARNING
Do
not secure any objects (e.g. coat hangers)
on the

NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
restraints are activated or when the side
impact air bags are deployed, or they can
prevent this

completely. The NECK-PRO head
restraints or side impact air bags can
therefore not provide the intended protection.
Do not use any seat or head restraint covers. G
WARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the

head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head 48

at eye level. This will reduce the potential for
injury
to
the head and neck in the event of an
accident or similar situation.
The NECK-PRO head restraints reduce the
likelihood of head and chest injuries. The
NECK-PRO head restraints on the driver's and
front-passenger seats are moved forwards
and upwards in the event of a rear-end
collision of a certain severity. This provides
better head support.
If the NECK-PRO head restraints have been
triggered in an accident, reset the NECK-PRO
head restraints on the driver’s and front-
passenger seat ( Y page 49). Otherwise, the
additional protection will not be available in
the event of another rear-end collision. You
can recognize when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted.
Resetting triggered NECK-PRO head
restraints G
WARNING
For
safety reasons, have the NECK-PRO head
restraints checked at a qualified specialist
workshop after a rear-end collision. G
WARNING
When pushing back the NECK-PRO head
restraint cushion, make sure your fingers do
not become caught between the head
restraint cushion and the cover. Failure to
observe this could result in injuries. X
Tilt the top of the NECK-PRO head restraint
cushion forwards in the direction of
arrow :.
X Push the NECK-PRO head restraint cushion
down in

the direction of arrow ; as far as
it will go.
X Firmly push the NECK-PRO head restraint
cushion back in the direction of arrow =
until the cushion engages.
X Repeat this procedure for the second
NECK-PRO head restraint.
i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have
difficulty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop. Seat belts
Important safety notes G
WARNING
Always
fasten your seat belt before driving off.
Always make

sure your passenger is properly
restrained. You and your passenger should
always wear seat belts.
Failure to wear and properly fasten and
position your seat belt considerably increases
your risk of injuries and their likely severity in
an accident.
If you are ever in an accident, your injuries
could be considerably more severe if you have
not fastened your seat belt correctly. If you do
not fasten your seat belt, you are much more
likely to collide with parts of the vehicle
interior or be ejected from it. This may result
in serious or fatal injury.
In the same crash, the possibility of serious or
fatal injury is considerably reduced if you wear
your seat belt properly. The air bags can only
offer the intended protection if the occupants
are wearing their seat belts properly. Occupant safety

Safety Z

G
WARNING
Never ride in a moving vehicle with the seat
backrest in
an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body. G
WARNING
Never
let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a

seat belt for more than one person at a
time. G
WARNING
Always
have damaged seat belts or seat belts
that have been subjected to a load in an
accident replaced and the anchorages
checked.
Only use seat belts that have been approved
by Mercedes-Benz.
Never tamper with seat belts. This can result
in the unintended deployment of the
Emergency Tensioning Devices or the failure
to deploy when necessary.
Do not bleach or dye seat belts, as this may
severely weaken them. In the event of a
collision, they may be unable to provide
adequate protection.
Have all work carried out only by qualified
technicians. Consult a qualified specialist
workshop.
The use of seat belts and infant and child
restraint systems is required by law in:
R all 50 states
R U.S. territories
R the District of Columbia
R all Canadian provinces Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
i
See "Children in the vehicle"
(Y page 54) for further information on
infants and

children traveling in the vehicle
as well as on child restraint systems.
Proper use of the seat belts G
WARNING
USE SEAT BELTS PROPERLY
R Seat belts can only work when used
properly. Never

wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in the
event of an accident.
R Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, knee bags, front-
passenger front air bag, side impact air
bags, head air bags), Emergency
Tensioning Devices (ETDs) and seat belt
force limiters. The system is designed to
enhance the protection offered to properly
belted occupants in certain frontal (front air
bags, knee bags and ETDs) and side (side
impact air bags, head air bags and ETDs)
impacts which exceed preset deployment
thresholds.
R Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder (it should not
touch the neck).50
