SRS (Supplemental Restraint System)
Introduction
Supplemental Restraint System (SRS) with:
R The 6 SRS warning lamp
R Air bags
R Air bag control unit (with crash sensors)
R Emergency Tensioning Device (ETD) for
seat belts
R Seat belt force limiters
SRS reduces the risk of vehicle occupants
coming into contact with parts of the vehi-
cle's interior in the event of an accident. It can also reduce the forces to which vehicle occu-
pants are subjected during an accident.
SRS warning lamp
GWARNING
If SRS is malfunctioning, restraint system
components may be triggered unintentionally
or might not be triggered at all in the event of
an accident with a high rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational read-
iness when the 6 SRS warning lamp goes
out while the engine is running. There is a malfunction if: R
the 6 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 6 SRS
warning lamp does not go out after a few
seconds
R the engine is running and the 6 SRS
warning lamp lights up again
Safety guidelines for seat belts, Emer-
gency Tensioning Devices (ETDs) and
air bags
GWARNING
R Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
R Air bags and pyrotechnic Emergency Ten-
sioning Devices (ETDs) contain perchlorate
material, which may require special han-
dling and regard for the environment.
Check your national disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm .
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETDthat has deployed must be replaced.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
R No modifications of any kind may be made
to any components or wiring of the SRS.
R Do not change or remove any component or
part of the SRS.
R Do not install additional trim material, seat
covers, badges, etc. over the steering
wheel hub, front-passenger front air bag

If the SmartKey is removed from the ignition
lock or is in position 0, the PASSENGER AIR
BAG OFF indicator lamp does not light up.
GWARNING
If the red 6 SRS warning lamp in the
instrument cluster and the 45 indica-
tor lamp light up simultaneously, the OCS is
malfunctioning. The front passenger front air
bag will be deactivated in this case. Have the system checked by qualified technicians as
soon as possible. Contact an authorized
Mercedes-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R When seated, a passenger should not posi-
tion him/herself in such a way as to cause
the passenger's weight to be lifted from the seat cushion as this may result in the OCS
being unable to correctly approximate the
passenger's weight category.
R Read and observe all warnings in this chap-
ter.
System self-test
The PASSENGER AIR BAG OFF indicator lamp
lights up if you:
R turn the SmartKey to position 1 or 2 in the
ignition lock
R press the KEYLESS-GO Start/Stop button
once or twice on vehicles with KEYLESS-GO
When an adult is sitting correctly on the front-
passenger seat and is categorized by the OCS system as an adult, the PASSENGER AIR BAG
OFF indicator lamp lights up and goes off
again after approximately six seconds.
If the seat is not occupied and the OCS sys-
tem classifies the front-passenger seat as
being empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up and not go out.
GWARNING
If the 4 5 indicator lamp does not illu-
minate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
For more information about the OCS, see
"Problems with the Occupant Classification
System" ( Y page 53).
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS oper-
ation. This could result in the front-passengerair bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with the child restraint system manufacturer's instal-
lation instructions.

Belt warning for the driver and front
passenger
Regardless of whether the driver's and front-passenger seat belts have already been fas-
tened, the 7 seat belt warning lamp lights
up for six seconds each time the engine is
started. It then goes out if the driver and the
front passenger have already fastened their
seat belts.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after a maximum of six seconds or once the driv-
er's seat belt is fastened.
If after six seconds the driver or front
passenger have not fastened their seat belts
and the doors are closed, the 7 seat belt
warning lamp lights up:
R until the driver's or front passenger's seat
belt is fastened
R if a vehicle speed of 15 mph (25 km/h) is
exceeded, a warning tone also sounds with
increasing intensity for a maximum of
60 seconds or until the driver or front-
passenger seat belt has been fastened
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the7 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains illu-
minated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 7 seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 7 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or R the vehicle is stationary and a door is open.
iFor more information on the 7 seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" ( Y page 260).
Emergency Tensioning Devices, seat
belt force limiters
GWARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist
workshop.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an accident, which will then need to be
replaced.
iVehicles with PRE-SAFE ®
: an electric
motor is used by PRE-SAFE ®
to trigger the
tightening of the seat belt in hazardous sit- uations. This procedure is reversible.
The seat belts for the front seats and rear
outer seats are equipped with Emergency
Tensioning Devices and seat belt force limit-
ers.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat posi-
tions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when: R the ignition is switched on
R the restraint systems are operational; see
"SRS warning lamp "( Y page 43)

Driving safety systems
Overview of driving safety systems
In this section, you will find information aboutthe following driving safety systems:
R ABS ( Anti-lock Braking System)
( Y page 68)
R BAS ( Brake Assist System) ( Y page 69)
R BAS PLUS ( Brake Assist System Plus)
( Y page 69)
R ESP ®
(E lectronic Stability Program)
( Y page 70)
R EBD ( Electronic Brake force Distribution)
( Y page 73)
R PRE-SAFE ®
Brake ( Y page 73)
Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Always adapt your
driving style to suit the prevailing road,
weather and traffic conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
The driving safety systems described only
work as effectively as possible when there is
adequate contact between the tires and the
road surface. Please pay special attention to
the notes on tires, recommended minimum
tire tread depths, etc. ( Y page 332).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as
effectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi- cle when braking.
The yellow ! ABS warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out when the engine is
running.
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Y page 68).
GWARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp ( Y page 262) and
display messages which may be shown in the
instrument cluster ( Y page 236).
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even if
you only brake gently.
Brakes
X If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel a pulsing in the brake pedal.
68Driving safety systems
Safety

Important safety notes
iObserve the "Important safety notes" sec-
tion ( Y page 68).
GWARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! If you test the parking brake using a brake
dynamometer, switch the ignition off.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
Vehicles without 4MATIC: observe the notes
on ESP ®
(Y page 327) when towing the vehi-
cle with a raised rear axle.
! Vehicles with 4MATIC: function or per-
formance tests may only be carried out on
a 2-axle dynamometer. Before you operate the vehicle on such a dynamometer, please
consult a qualified workshop. You could
otherwise damage the drive train or the
brake system.
ESP ®
is only deactivated if the å warning
lamp is lit continuously.
If the ÷ warning lamp and the å warn-
ing lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
( Y page 264) and display messages which
may be shown in the instrument cluster
( Y page 236).
iOnly use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
Characteristics of ESP®
General information
If the ÷ ESP®
warning lamp goes out
before beginning the journey, ESP ®
is auto-
matically active.
If ESP ®
intervenes, the ÷ ESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X Only depress the accelerator pedal as far as
necessary when pulling away.
X Adapt your driving style to suit the prevail-
ing road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts automati-
cally when the driver wants to pull away again. ESP ®
remains in its previously selected sta-
tus. Example: if ESP®
was deactivated before
the engine was switched off, ESP ®
remains
deactivated when the engine is switched on
again.
Deactivating/activating ESP®
Important safety notes
iObserve the "Important safety notes" sec-
tion ( Y page 68).
You can select between the following sta-
tuses of ESP:
R ESP ®
is activated.
R ESP ®
is deactivated.
GWARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
