iWhen you switch on ignition, the indi-
cator and warning lamps (except high
beam headlamp indicator lamp and
turn signal indicator lamps unless acti-
vated) in the instrument cluster come
on. The indicator and warning lamps
(except high beam headlamp indicator
lamp and turn signal indicator lamps if
activated) will go out when the engine
is running. This indicates that the re-
spective systems are operational.iVehicles with automatic transmission*:
The SmartKey can only be removed
from the starter switch with the gear
selector lever in positionP.
!If the SmartKey cannot be turned in the
starter switch, the vehicle battery may
not be sufficiently charged.
Check the vehicle battery and
charge it if necessary (
page 421).
Get a jump start (
page 424).
To prevent accelerated vehicle battery
discharge or a completely discharged
vehicle battery, always remove the
SmartKey from the starter switch when
the engine is not in operation.

wiper blades when wiping occurs on a
dry windshield. If it is necessary to op-
erate the wipers in dry weather condi-
tions, always operate the windshield
wipers with windshield washer fluid

69 Safety and Security
Occupant safety
When you sell your vehicle, we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
and installation of additional electri-
cal/electronic equipment on or near
SRS components and wiring. Keep area
between air bags and occupants free
from objects (e.g. packages, purses,
umbrellas, etc.).
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
Never place your feet on the instrument
panel, or on the seat. Always keep both
feet on the floor in front of the seat.
Air bag system components will be hot
after an air bag has inflated. Do not
touch.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended
air bag deployment. Work on the SRS
must therefore only be performed by
qualified technicians. Contact an autho-
rized Mercedes-Benz Center.
For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.
Given the considerable deployment
speed and the textile structure of the
air bags, there is the possibility of abra-
sions or other injuries resulting from
air bag deployment.
Warning!
G
Only use seat covers which have been test-
ed and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the head-thorax airbags. Contact your au-
thorized Mercedes-Benz Center for availabil-
ity.

air bags
The air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The passenger air bag will only be de-
ployed if

the impact exceeds a preset deploy-
ment thresholdKneebags
The driver-side kneebag is located on the
driver’s side lower instrument panel. The
passenger-side kneebag is located on the
passenger side below the glove box. They
are designed to operate together with the
air bags in certain frontal impacts exceed-
ing a preset threshold. The kneebags oper-
ate best in conjunction with properly
positioned and fastened seat belts.
!Do not place objects heavier than
20 lbs (9 kg) on the passenger seat.
This could cause the front air bag or
head-thorax air bag on the passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

74 Safety and SecurityOccupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with
emergency tensioning devices (ETDs) and
seat belt force limiters.
The ETD is designed to activate in the fol-
lowing cases:
in frontal or rear-end impacts exceed-
ing a preset severity level.
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 64).In an impact emergency tensioning
devices remove slack from the belts in
such a way that the seat belts fit more
snugly against the body. Belt force limiters
reduce the force exerted by the seat belts
on occupants during a crash.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.
Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
iThe ETDs for the seats will only activate
if the respective seat belt is fastened
(latch plate properly inserted into
buckle).
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When scrapping the emergency tensioning
device, our safety instructions must be fol-
lowed. These are available at your autho-
rized Mercedes-Benz Center.
