Rear seat belt status indicator Example: rear-compartment sea
tbelts tatus indi-
cator
The rear-comp artment sea tbelt status indi-
cator indicates the rear seat on which the belt
is fastened. The status indicator displays peo-
ple in the direc tion of travel. In the example,
the passenger sonthe outer seats in the rear
hav etheir seat belts fastened. The üsym-
bol in the multifunction displa yindicates a
fastened sea tbelt. If aseat belt is not fas-
tened or if aseat is not occupied, the ý
symbol is displayed. The rear-compartment seat belt status indi-
cator appear

Bel ttensioners, belt force limiters G
WARNING
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 aqualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. An yMercedes-Benz
Ser vice Centre can provid edetails of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckl eonthe front-passenger seat.
Otherwise, the belt tensioner could be trig-
gere dint he even tofanaccide nt.
X In order to ensur ethat the pyrotechnic seat

R driver's and front-passenger seat
R the outer seats in the second row
R the seats in the third row
The belt tensioners tighten the seat belts in
an accident ,pulling them close against the
body.
Belt tensioners do not correc tincorrect seat
positions or incorrectly fastened sea tbelts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fit tedw ithabelt force
limiter and this is triggered, the force exer ted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the fron tseats are
synchronised with the fron tairbags, which
tak eona part of the deceleration force. This
result sinthe force exerted on the occupant
being distributed over agrea tera rea.
Th eb elt tensioners can only be activa ted
when:
R the ignition is switched on.
R the restraint system sare opera tional; see
"SR Swarnin glamp" (Y page 41).
The belt tensioners on the outside seats in the
second row and on the seats in the thir drow
ar et riggere dindependently of the lock status
of the sea tbelts.
The belt tensioners are triggere ddepending
on the type and severity of an accident:
R if, in the even tofahead-on or rear-end col-
lision, the vehicle decelerates or acceler-
ates rapidly in alongitudinal direction dur-
ing the initial stages of the impact
R if, in the even tofaside impact, on the side
opposit ethe impac tthe vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R in certain situations where the vehicle over-
turns and the system determines that it can
provide additional protection If the airbags are deplo
yed,you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will th ebang
affect your hearing. The powde rthat is
released generally does not constitute a

Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50 mtall and under
twelve years of age must always be secured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with achild secured in arear-
ward-facing child restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint
system with transponders for automatic
chil dseat recognition
R if you secur eaforward-facing child
restraint system to the front-passenger
seat, you must mov ethe front-passenger
seat as fa rback as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. 50

ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alway srest on the seat
cushion. An incorrec tlyf itted child restraint
system cannot perfor mits intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. Thi scan lead to a
system malfunc tion. This may cause the

(Y page 396).
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains .Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page61). G
WARNING
If ABS is faulty, the wheels could lock when
braking .The steerability and brakin gcharac-
teristics ma ybeseverely impaired. Addition-
ally, further driving safet ysystems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diatel yata qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the infor mation on the ABS warning lamp (Y
page 326) and
display messages which may be shown in the
instrument cluster (Y page 291).
ABS regulate sbrake pressure in such away
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from aspeed of about 8km/h
upwards, regardless of road-surfac econdi-
tions. AB Sworksons lippery surfaces, even
when you only brake gently.
The yellow !ABS warnin glamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To mak eafull brake application:
depress th ebrake peda lwith full force.
If ABS intervenes when braking, you will feel
ap ulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as areminder to take extr acare while
driving.
Off-road ABS An ABS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated on:
R
Vehicles without the ON&OFFROAD pack-
age (Y page 252)
R Vehicles with the ON&OFFROAD package
(Y page 253)
At speeds below 30 km/h, the front wheels
lock cyclically during braking. The digging-in
effect achieved in the process reduces the
stopping distance when driving off-road. This
limits steering capability. Driving safety systems

When the distan
cewarning function is acti-
vated, the multifunction display shows the
Ä symbol as long as the HOLD function is
not activated (Y page 211). On vehicles with
Active Parking Assist, the Äsymbol is dis-
played when position Pis engaged or you are
driving faster than 35 km/h.

The distan cewarning function will issue a
warning at speed sofaround 30 km/h or
more if:
R thed istanc etothe vehicle in fron tist oo
short for the speed you ar edriving at for
severa lseconds. The ·distan cewarn-

For the distanc ewarning function to assist
you when driving, the function must be acti-
vated in the on-board computer and be opera-
tional (Y page 278).
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar senso rsystem, the
distanc ewarning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
At speeds up to approximately 70 km/h, the
distance warning fun ction may also detect stationary obstacles, for example, stopped or
parked vehicles.
If you approach an obstacle and the distance
warnin gfunction detects arisk of acollision,
the system will initially aler tyou both visually
and acoustically.
In particular ,the detection of obstacles can
be impaired if ther eis:
R dir tont he sensors or anythin gelse cover-
ing the sensors
R snow or heavy rain
R interferenc ebyother radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
R an arro wvehicle travelling in front, e.g. a
motorcycle
R av ehicle travelling in fron tonadifferent

Following damage to the fron tend of the vehi-
cle ,havet he configuration and operation of
the radar sensor checked at aqualified spe-
cialist workshop. This also applie stoc olli-
sions at slow speeds where ther eisnovisible
