2011 MERCEDES-BENZ CLS COUPE Owners Manual

Fron
tairbags The fron
tairbags increase protection for the
driver's and front-passenger's head and
chest. Driver's airbag
:deploys in front of the
steering wheel; front-passenger airbag ;
deploys in front of and above the glove com-
partment.
They are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deploymen tcan offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbag sinthe vehi-
cle
If the vehicle overturns, the front airbags are
generally not deployed unless the system
detects high vehicle deceleration in a longi-
tudinal direction.
Front-passenger airbag ;is only deployed if
the front-passenger seat is occupied or if the
4 PASSENGER AIRBAG OFF indicator
lamp in the centre console is not lit
(Y page 48). This means that a child
restraint system with automatic child seat
recognition has not been fitted to the front-
passenger seat or has been fitted incorrectly.
! Do not place heavy objects on the front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied.
In the event of an accident, the restraint systems on the front-passenger side are
triggered. Have restraint systems that have
been triggered replaced.
Driver's kneebag i
The driver's kneebag is only available in
certain countries.
The driver's kneebag increases protection of
the driver against:
R knee injuries
R thigh injuries
R lower leg injuries Driver's kneebag
:is always deployed along
with the driver's airbag and inflates under-
neath the steering column.
Sidebags G
Risk of injury
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat covers must have a special tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
covers can be obtained, for example, from a
Mercedes-Benz Service Centre. 38
Occupant safetySafety

When deployed, the sidebags offer additional
protection for the thorax of the vehicle occu-
pants on the side of the vehicle on which the
impact occurs .However, they do not protect
the:
R head
R neck
R arms Fronts
idebags :and rear sidebags ;
deploy nex tto the outer seat cushions.
The sidebags 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 accelera-
tion, e.g. in a side impact
R independently of seat belt use
R independently of the front airbags
R independently of the belt tensioners
If the vehicle overturns, the sidebags are gen-
erally not deployed. They are deployed if the
system detects high vehicle deceleration or
acceleration in a lateral direction and deter-
mines that sidebag deployment can offer
additional protection to that provided by the
seat belt.
Pelvisbags i
Pelvisbags are only available in certain
countries. G
Risk of injury
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you only use seat covers that have been approved
for Mercedes-Benz vehicles.
The seat covers must have a special tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
covers can be obtained, for example, from a
Mercedes-Benz Service Centre.
Pelvisbag deployment enhances the level of
protection of the vehicle occupants on the
side of the vehicle on which the impact
occurs. Pelvisbags
:deploy next to and below the
outer seat cushions. They 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 accelera-
tion, e.g. in a side impact
R independently of seat belt use
R independently of the front airbags
R independently of the belt tensioners
The pelvisbags are generally not deployed if
the vehicle overturns, unless the system
detects high vehicle deceleration or acceler-
ation in a lateral direction and determines
that they can offer additional protection to
that provided by the seat belt.
Windowbags The windowbags enhance the level of protec-
tion for the head (but not chest or arms) of Occupant safety
39Safety Z

the vehicle occupants on the side of the vehi-
cle on which the impact occurs.
The windowbags are integrated into the side
of the roo
fframe and deploy in the area
extending from the front door (A-pillar) to the
rear door (C-pillar). Windowbags
: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 deceleratio noraccelera-
tion, e.g. in a side impact
R regardless of whethe rthe front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
R independently of the front airbags PRE-SAFE
®
(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or intervenes powerfully in vehicles with DISTRONIC PLUS, BAS PLUS
or PRE-SAFE ®
Brake
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical situations involving driving
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R vehicles with a multicontour seat or an
active multicontour seat: the air pressure
in the side bolsters on the seat cushion and
the side bolsters on the backrest is
increased.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroof and the side win-
dows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat/active
multicontour seat is reduced again. All set-
tings 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 releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped. 40
Occupant safetySafety

!
Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.
More information aboutb elt adjustment, a
convenience function integrated into PRE-
SAFE ®
, can be found in the "Belt adjustment"
section (Y page 43). NECK-PRO head restraints/NECK-
PRO luxury head restraints
NECK-PRO head restraints/NECK-PRO luxury
head restraints increase protection of the
driver’s and front-passenger’s head and neck.
In the event of a rear collision of a certain
severity, the NECK-PRO head restraints/
NECK-PRO luxury head restraints on the driv-
er's and front-passenger seats are moved for-
wards and upwards. This provides better
head support. G
Risk of injury
Head restraint covers prevent NECK-PRO
head restraints/NECK-PRO luxury head
restraints from triggering properly. The NECK-
PRO head restraints/NECK-PRO luxury head
restraints can therefore not provide the inten-
ded protection .Do not use head restraint cov-
ers.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraints have been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver's and front-passenger seats
(Y page 41). Otherwise, the additional pro-
tection will not be available in the event of
another rear-end collision. NECK-PRO head
restraints/NECK-PRO luxury head restraints
that have been triggered are moved forwards
and can no longer be adjusted. Resetting triggered NECK-PRO head

Important safety guidelines Mercedes-Benz recommends that you have
NECK-PRO head restraints/NECK-PRO luxury
head restraints checked at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre, if your vehicle is involved in a
rear-end collision.

Important safety notes Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the ris
kofvehicle occupants coming
into contact with parts of the vehicle interior. G
Risk of injury
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its intended
protective function. Under certain circum- stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupants –inparticular,
pregnant women – wear their seat belt cor-
rectly at all times.
R The seat belt must fit snugly on your body
and must no tbe twisted. Therefore, avoid
wearing bulky clothing, e.g. a winter coat.
The shoulder belt section must be routed
across the centre of your shoulder – on no
account across your neck or under your
arm –and pulled tight against your upper
body .The lap belt must always pass across
your lap as low down as possible, i.e. over
your hip joints –not across your abdomen.
If necessary, push down the belt strap
slightly and then retighten it in the roll-up
direction.
R Do not route the belt strap across sharp
edges or fragile objects, especially if these
are located on or in your clothing, e.g. spec-
tacles, pens, keys, etc. The seat belt strap
could be damaged and tear in an accident,
and you or other vehicle occupants could
be injured.
R Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of other occupants. It
would not be possible to restrain the child
in the event of a sudden change in direc-
tion, braking or an accident .This could
result in severe or even fatal injuries to the
child and other occupants.
R Persons less than 1.50 m tall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 mtall in spe-
cially designed, suitable restraint systems.
R Children less than 1.50 m tall or under 12
years of age canno twear the seat belts
properly. Therefore, they should always be
secured in a suitable child restraint system
on a suitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufacturer's 42
Occupant safetySafety

installation instructions when fitting a child
restraint system.
R Do not secure any objects with a seat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
Risk of injury
The seat belt does not offer the intended level
of protection unless the backrest is almost
vertical. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
Risk of injury
Ad irty or damaged seat belt or a seat belt that
has been subjected to a load in an accident
or which has been modified no longer offers
the intended level of protection. Under certain
circumstances, this could cause severe or
even fatal injuries in the even tofanaccident.
For this reason, check regularly that the seat
belts are not damaged or dirty.
Always have damaged sea tbelts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop. Consult a qualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle. Fastening seat belts
X

Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts .Itmay light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt .Ift he vehicle is stationary and a door is
opened, the 7seat belt warning lamp
goes out and the warning tone ceases.
For certain countries only: regardless of
whether the driver or the front passenger
have fastened their seat belts, the 7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Indicator and warn-
ing lamps in the instrumentc luster, seat
belt" (Y page 239).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. 44
Occupant safetySafety

The rear-compartmen
tseat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again.
You can also cancel the rear seat belt status
indicator immediately (Y page 215).
i The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
!
If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupan tis
reduced.
The front beltf orce limiters are synchronised
with the front airbags, which take on a part of
the deceleration force. Thus, the force exer-
ted on the occupant is distributed over a
greater area. The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 35).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensioners on the seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R in the event of a side impact, on the side
opposite the impact if the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R in certain situations if the vehicle overturns
and the system determines that it can pro-
vide additional protection
If the airbags are deployed, you will hear a
bang and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up. G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations. Occupant safety
