can therefore be detected in good time.
The 1 warning lamp in the instrume nt

delay of no more than a few seconds after
the engine is started.

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

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

Driving safety
systems
In this section, you will find information
about the following driving safety system s:
! ABS(A nti-lock B raking S ystem)
! BAS (B rake As sist)
! ESP (E lectronic S tability P rogram)
i In wintry conditions, use winter tyres (M+S
tyres), with snow chains if ne cessary. The maxi-
mu m effect of ABS, BAS, ESP and SBC can only
be ac hievedin this way. ABS regulates the brake
pressure insuch a
way that the wheels do not lock when you
brake. This allows you to continue steer-
ing.
ABS works from a speed of approxi mately
8 km /hupwards, regardless of road sur-
face conditions.
ABS works on slip pery road surfaces, even
when you only brake gent ly.
The - indicator lamp in the instrument
cluster ( =page 12 )light s up when you
turn the keyto position 2in the ignition
lock. It goes out when the engine isrun-
ning. This indicates that ABS is opera-
tional. Dr
iving safety systems G
Risk of accident The risk of an acci
dent increases especially if
you:
! drive too fast, particularly when cornering
and ona wet or slippery road surfa ce
! drive too close to th evehicle in front
The driving safety systems described in this
section are unable to reduce this risk or over-
ride the laws of physics.
For this reason, always adapt your driving
style to suit the current road and weather con-
ditions and maintain asuffici en tdistanc efrom
other road users and objectsonthe road. ABS
G
Risk of accident Do not depress the brake pedal several times
in
qu ick succession (pumping). Depress the
brake firmly and evenly .Pumping the brake
ped alreduces the braking effect. 209en_d2.boo Seite

Safety
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
