Getting started
Driving
The < seat belt warni ng lamp in the
instrument cluster reminds you to ensure
that all occupants are wearing their seat
belts.
If the driver has not fastened his seat belt,
the < seat belt warning lamp lights up
if the doors are closed and the engine is
running. In addition, an intermitten tsignal
sounds from a speed of 25 km /hupwards.
The intermittent signal ceases:
! as soon as the driver has fastened his
seat belt
! after a maximum of 93 seconds
! when the vehicle is stationary
The < seat belt warning lamp only goes
out once the driver has fastened his seat
belt. !
Children less than 1.50 m tall and
yo un ger than 12 years ofage cannot
wear the seat belts properly. Always
secure these children in suitable child
re straint systems on seats designe dfor
this purpose ( =pag e62). Please follow
the manufacturer's installation instruc-
tions when installing child restraint sys-
tems.
! Do not secure any objects with a seat
belt if it is also being used by one of the
vehicle 'soccupan ts. G
Risk ofinjury The seat belt only prov
ides its intended
degree of protection if the seat backrest is
positioned as close to the vertical as possi-
ble, allowing th eoccupant to sit upright.
Avoid sea tpositions which do not allow the
seat belt to be routed correctly ( =
pag e25).
Therefore, po sition the bac kres ts as close to
the vertical as possible. Never drive with the
backrest inclined too far backwards. G
Risk of injury Airbags are de
signed not to be triggered in
al lac cident situations, since aco rrectly fas-
tened seat belt will often besufficient for
providing an effective degree of protection.
Airbags are not a substitute for seat belts.
To reduce the risk of severe or eve nfatal
in jury, make sure that all occupants – in par-
ticular, pregnant women – always wear their
seat be lts correctly, are seated inan upright
positio nand have their seats positio ned
almost vertic ally ( =

Occupant safety
Triggering ofbelt tensioners, belt force limiters and
airbags
In the event ofa collision, the sensor in the
airbag contro lunit evaluates important
physical data, such as duration, direction
and rate of veh icle deceleration or acceler-
ation. Based on this evaluation and pre-
emptively, the belt tensioners are the first
to be triggered by the airb agcontrol unit in
a collis ion with longi tudinal deceleration as
a function of the rate of vehicle decelera-
tion.
The front airbags are not triggered unless a
second activation threshold is reached, i.e.
an even higher rate of vehicle deceleration
in the longitudinal direction is exceeded. i
Thefront airbag on the front-passenger side
is only tri ggered if:
! the front-passenger seat oc cupancy sensor
has detected that the seat is occupied
! the PASSENGER AIRBAG OFF warning lamp
onthe centre console is not lit (
=page 64)
The belt tensioners are only activated if the seat
belt buck le tongue is correctl yengaged in the
se at belt buckle.
Criteria for the activation of belt
tensioners and airbags
To determine whether it is necessary to
activ ate a belt tensioner or airbag, the air-
bag control unit evaluates the duration and
direction of vehicle deceleration or accel-
eration during the initial phase of the colli-
sion.
The activation thresholds for the belt ten-
sioners and the airbags are variable and
are adapted in accordance with the rate of
ve hicle deceleration. This process ispre-
emptive in nature as airbag deployment
must take place during the impact and not
at the end of the collision. G
Risk of inju ry A malfu
nction has occurred if the 1
warning lamp:
! doesnot com eon when yousw itchon
th eignition
! does not go out after a few seconds
when the engine is running
! comes on again
Individ ual systems could beactivated inad-
verte ntly or may not be triggered at all in the
event of an accident with a high rate of vehi-
cle deceleration. Ifthis happens, have the
SRS system checked and repaired immedi-
ately at a qualified specialist wor kshop
wh ich has the necessary specialist know-
ledg eand tools to carry out the work
require d.
Mercedes-Benz recomme nds that youuse a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-re lated systems must be car-
ried out at a qualified specialist workshop. 209en_d2.boo Seite

Occupant safetyi
Belt tensioners do not correct:
! inco rrect sitting positions
! incorrectly worn seat belts
Belt tensioners do not pull occ upants back
towar dsthe backrests.
The belt force limiter reduces the belt
force on the occupant when a belt ten-
sioner is activated.
The belt force limiter is fine-tuned to the
front airbag, which takes over from the
seat belt a part of its restraining forces,
thus spreading the forces exerted on the
occupant over a greater area.
The automatic comfort-fit feature on the
front seats reduces the retraction force of
the seat belts.
When the igniti onisswit ched on, the belt
tensioner will be triggered:
! only if the res traint systems are opera-
tional (the 1warning lamp lights up
after the ignition is switched on and
goes out when the engine is running)
( = page 12) !
forea ch lap- shou lder sea tbe lt, pro-
vided the belt tongue is engaged inthe
seat belt buckle
! if a head-on or rear-end col lision occurs
and the veh icle decelerates or acceler-
ates rapidly ina longitudinal direction
during the initial stages ofthe collision
! on the front-passenger side only ifthe
front-passenger seat is occupied and
the belt tongue is engaged in the seat
belt buckle
! in the event of a severe fronta limpact
if the vehicle decelerates rapidly in a
longitudinal direction during the ini tial
stages of the collision
If the be lttensioners are tri ggered, you will
hear a bang that is genera lly harmless to
your hearing. A small amount of dust may
also be released. The 1warning lamp
lights up.
An indication that a belt tensioner in there ar has
been trigger edisthat the seat belt buckle is
pu lled down and is almost flush with the topof
the seat. G
Risk ofinjury The
belt tensioners in the rear only function
correctly ifthe buckl escan be pulled down
unimpeded.
Since this downwards movementmust not
be restricted:
! Do not grasp the buckles.
! Do not pl ace any obj ects un derneath
the buckles.
Ot he rwi se, the action of the belt tensioners
will beimpaired or completely ineffective.
You will then have no additional prot ection. 209en_d2.boo Seite

The airbag inflates in milliseconds. The
1 warning lamp lights up. i
Ifth e airba gsare triggered, you will hear a
bang and asmall amount ofdust may also be
released. This bang will not damage your hearing
and the dust does not constitu te ahealth hazard.
Airbag inflation slows down and restricts
the mo vement of the vehicle occupant.
If a vehicle occupant comes into contact
with an airbag which has been triggered,
the airbag will release some hot gas. This
feature is designed to reduce the force act-
ing on the occupant's head and ch est.
These airbags are theref orein a depress u-
rised state follo wing the accident. !
Do not lean forwards , e.g. over the pad-
ded boss of the steering wheel, particu-
la rly while the vehicle is in motion.
! Do not put your feet on the dashboard.
! Only hold the steering wheel by the rim.
This allows the airbag to inflate fully.
If you hold the ins ideo f the steering
wheel, you could be injured if the airbag
is triggered.
! Do not lean on the doo rsfrom inside the
vehicle.
! Donot place any objects onthe airba gs
or between the airbags and the vehicle's
oc cupants.
! Donot ha nganyha rd obje cts, e.g. coat
hangers ,on the grab handles or coat
hook s.
Because of the high speed at which airbags
have to inflate, it is not possib leto rule out
entire lythe risk of injurie scaused by an
inflating airbag. 209en_d2.boo Seite

The purpose of head/thorax airbag deploy-
ment is to enhance the protection for the
he ad and chest (but not the arms)of the
ve hicle occupants on the side of the vehi-
cle on whi chthe impact occurs. The head /
thorax airbags are fitte din the outer sides
of the front seat backrests and in the side-
wall in the rear. Th
e hea d/thor ax airbags are trigger ed:
! inthe first stages of an accident with
high lateral forces of vehicle decelera-
tion or acceleration
! on the side on which an impact occurs
! ifthe system foresees that airbag
deployment can offer additional pro-
tection to that provided by the seat belt
! ifthe seat belt is fas tened
! independently of the front airbags
The front-passenger head /thorax airbag
wi ll only be triggered ifthe front-passenger
seat has objects placed onit or if it is actu-
ally occupied.
On vehicles with automatic child seat rec-
ognition on the front-passenger seat, the
front-passenger head /tho rax airbag will
only be triggered if the PASSENGER
AIRBAG OFF warning lamp on the centre
console is lit, i.e. a child seat with auto-
matic child seat recognition transponder
is installed on th isseat. In an accident, the head
/thorax airbag
inflates in the area of the front side win-
dow.
i You will find further information about air-
bag inflation on ( =
page 54).
You will find furt herin formation about the trig-
gering of belt tensioners and belt force limiters
on ( =
page 50). G
Risk ofinjury Ob
serve the following notes to reduce the
ris kof serious or fatal injury if the hea d/
thorax airbag is triggered:
! Vehicle occupants – in particular, chil-
dren – must never lean their head into
the area of the window in which the
head /thorax airbag is trigg ered.
! Vehicle occupants must wear their seat
belt corr ectly at all times.
! Always secure children less than 1.50 m
tall and under twelve years of age insuit-
able child restraint systems. G
Risk of inju ry For safety reasons, Mercedes-Benz recom-
me
nds that you use seat cove rs that have
been approv edfor Mercedes-Be nzvehicle s.
Otherwise, a head /thorax airbag may not
inflate correctly and could fail to provide its
intended pro tective function in the event of
an accident. These co vers can be obtained
from a Mercedes-Benz Servi ceCentre, for
example. 209en_d2.

Rearward-facing child seat warning symbol Automat
icchild seat rec ognition
The sensor system for the front-passenger
seat automatical lyrecognises whether a
special Mercedes-Benz rearward-facing
chi ldseat is fitted. If this is the case, the
PASSEN GER AIRBAG OFF warning lamp on
the centre console lights up. G
Risk of inju ry A rearward-faci
ngchild restraint system
must not be used on a seat protected by an
ai rbag install edinfront ofthe seat unless
the airbag is deactivated. To make this clear,
an appropriate warning sticker is affixed to
either side of the front-passenger sun visor. G
Risk of inju ry A rearward-faci
ngchild restraint system
must not be used on a seat protected by an
ai rbag install edinfront ofthe seat unless
the airbag is deactivated.
On the front-pass enger seat, only use child
restraint systems with automatic child seat
recognition which have been recommended
for Mercedes-Be nzvehicl es. You can obt ain
information from any Mercedes-Benz Serv-
ice Centre.
If yo u usearearward-facing child seat on
the front-passenger seat, it must be a spe-
cial Mercedes-Be nzrearward- facing child
seat with automatic ch ild seat recognition. If other rearward-facing child seats are used
on th efront-passenger seat, the front-pas-
senger airbag is not deactivated and the
child could be seriously or fatally injured by
the airb aginflating. To makethis clear,an
appropriate warning symbol is affixed in the
cockpit.
If you use a forward-facing child seat with-
out automatic child seat recognition on the
fr ont-passenger seat, you must move the
fr ont-passenger seat to its rearm ostp osi-
tion.
Do not leave children unsupervised in the
vehi cle, even if they are sec ured in a child
restraint syst em. They would otherwise be
unable to res cue them selves if danger
threatens ,e.g.ex ces sive heat. Or the ycould
oth erwi se be injured by moving parts in the

ai rbag and the belt tensioner on the front-pas-
se nger side remain active even if the front -pas-
senger airb agis deactivat ed. ISOFIX
child seat secur ing system*
ISOFIX is a standardised securing system
for speci alchild seats in the rear. The
securing rings provided for two child seats
are located on the left andright-hand sid es
of the rear seats bet ween the seat cush-
ions and the ba ckrest. G
Risk ofinjury If the front-passenger front airbag warning
lamp does not light up when the child seat is
fitted, the front-passenger front airbag has
not been de
activated. The child could suffer
life-t hreatening injuries if the front-passen-
ger front airbag deploys. If the above warn-
ing lamp does not light up when the child
seat is fitted, proceed as follows:
! Do no tuse a rearward-facing child seat
on the fr ont-pass engerse at.
P68.10-3078-31 !
Fit the rearward-facing child seat on a
suitable rear seat.
or
! Use a forward-facing child seat onthe
fr ont-passen gers eat. In this case, you
must move the front-passenger seat to
its rearm ostp osition.
! Have the automatic child seat recogni-
tion checked at a qualified specialist
workshop which has th eneces sary spe-
cialist knowledge and tools to carry out
the work required. Merc edes-Benz rec-
om mends that you use a Mer cedes-
Benz Service Centre for this purpose.
In particular, work re levant to safety oron
safety-relat edsystems must be carried out
at a qualifie dsp ecialist workshop. G
Risk of inju ry A child restraint system secured by the
ISOFIX child seat securing system does not
pro
vide sufficient protection for children
weighing more than 22 kg. For this reason,
do not secure childre nweighing more than
22 kg in a chi ldrestra int system securedby
the ISOFIX child seat sec uring syste m.If the
child weighs more than 22 kg, you should
secure the child restraint system using a

Driving safety systems Braking
If ABS cuts in while you are braking, you
will feel:
!
the vehicle vibrating
! the brake pedal pulsating
This will indicate to you that ABS has been
acti vated. Always adapt your driving style
to suit the prevai ling road and weather
conditions.
6 Continue to depress the brake pedal,
even when ABS has been activ ated. Brake Assist operates
inemergency brak-
ing situation s.If you depress the brake
pedal quickly, BAS boosts the braking
force automatically and thus shortens the
stopping distance.
6 Depress the brake pedal firm lyuntil the
emergency-braking situation is ove r.
ABS prevents the wheels from locking.
When you release the brake pedal, the
brakes work as norm al again. BAS is then
deactivated. The Electronic Stabilit
y Program monitors
the traction, i.e. the power transmission
between the tyres and the road, and the
stability of the vehicle.
ESP detects when a wheel is spinning or
when the vehicle has begun to skid. ESP
stabilises the vehicle by applying specific
braking to individual wheels and limiting
the engine power output. ESP assists you
in particular when pulling away on a wet or
slip pery road surface.
If ESP cuts in, the vwarning lamp
flashes in the speedometer.
The v ESP warning lamp in the instru-
ment cluster lights up when you turn the
key to po sition 2in the ignition lock. It
goes out when the engine is running. This
ind icates that ESP is operational. G
Risk of accident Always adapt your driving style to suit the
prevailin
groad and weather conditions and
maintain a suffi cient distance from other
road users and objects onthe road. BAS
G
Risk of accident If BAS malfunctions, the brake system is still
available with the full brake boosting effect.
In an emer
gency braking situation, however,
th e braking fo rce is not automatically
bo osted and may lengthen the stopping dis-
tance. ESP209en_d2.boo Seite
