SRS (Supplementa
lRestraint System)
Introduction SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consistso f:
R 0075 SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R Emergency Tensioning Devices
R seat belt force limiters
SRS warning lamp G
WARNING
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 ahigh rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at aq ualified 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 0075 SRS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out no later than afew seconds
after the engine is started.
The SRS components are in operational read-
iness when the 0075SRS indicator lamp goes
out while the engine is running. There is
amalfunction if:
R the 0075 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 0075SRS
warning lamp does not go out after afew
seconds
R the engine is running and the 0075SRS
warning lamp lights up again
Safety guidelines for seat belts, Emer-
gency Tensioning Devices (ETDs) and
air bags G
WARNING
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 suppliedbyana uthorized
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

Perchlorate/index.cfm .
R Air bags and ETDs are designed to function
on aone-time-only basis. An air bag or ETD
that has deployedm ust 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 acrash 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 componen tor
part of the SRS.
R Do not install additional trim material, seat
covers, badges, etc. over the steering

Characteristics of activated SPORT han-
dling mode
SPORT handling mode raises the intervention threshold for stabilizing the vehicle. This
allows for asportier driving style on desig-
nated race circuits and may in certain situa-
tions improve the traction in comparison with
ESP ®
.
If SPORT handling mode is activated and one or more wheels start to spin, the 0089warn-
ing lamp in the instrument cluster flashes.
ESP ®
only stabilizes the vehicle to alimited
degree.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly.
R engine torque is only restricted to alimited
degree, and the drive wheels are able to
spin. The spinning wheels produce acut-
ting effect for better traction. Characteristics when ESP
®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 0089warning lamp in the
instrument cluster does not flash. In such sit-
uations, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning
of the wheels results in acutting action for
better traction.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 54).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapty our driving style
to the different handling characteristics. Have the brake system checked at aqualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 192) as well as dis-
play messages (Y page 166). ADAPTIVE BRAKE

WARNING
When leaving the vehicle, alwaysr emove the
SmartKey from the ignitio nlock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secure dinachild
restraint system, and do not give them access to an unlocked vehicle. Achild's unsupervised
access to avehicl ecouldr esult in an accident
and/or serious personal injury .They could:
R injure themselves on vehicl eparts
R be seriouslyorf atally injured by extreme

R injure themselves or have an accident with
vehicl eequipment that may still be in oper-
ation even after the SmartKey has been
removed from the ignition, such as the seat
adjustment, steering whee ladjustment or
memory function.
If children open adoor, they coul dcause
severe or even fatal injury to other persons; if they get out of the vehicle, they coul dinjure
themselves when doing so or be seriouslyor
even fatally injured by any passing traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, coul dbecome very
hot, and achild coul dbeburned on these
parts. G
WARNING
If you attach heavy or larg eobjects to the
SmartKey ,the SmartKey coul dbeuninten-
tionally turned in the ignitio nlock. This could
caus ethe engine to be switched off. There is a
risk of an accident.
Do not attach any heavy or larg eobjects to the
SmartKey .Remove any bulky key rings before
inserting the SmartKey into the ignitio nlock.
