RAir bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that is deployed must be replaced.
RDo not pass seat belts over sharp edges.
They could tear.
RDo not make any modification that could
change the effectiveness of the seat belts.
RDo not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
RNo modifications of any kind may be made
to any components or wiring of the SRS.
This includes changing or removing any
component or part of the SRS, the
installation of additional trim material, seat
covers, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat
backrests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or near
SRS components and wiring. Keep area
between air bags and occupants free of
objects (e.g. packages, purses, umbrellas,
etc.).
RDo not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
RAir bag system components will be hot after
an air bag has inflated. Do not touch them.
RNever place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RIn 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 authorized
Mercedes-Benz Center.
RFor your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
RGiven the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, we strongly
recommend that you inform the subsequent
owner that the vehicle is equipped with SRS
and refer them to the applicable section in the
Operator’s Manual.
Front air bags 
GObserve Safety notes, see page 33.
Driver’s front air bag : and front passenger
front air bag ; are designed to provide
increased protection for the driver and front
passenger against the risk of injuries to the
head and thorax.
Driver and front passenger front air bags are
deployed
Rin the event of certain frontal impacts
Rif impact exceeds a preset deployment
threshold

2Ignition (power supply for all electrical
consumers) and driving position 
3Starting positionWhen you switch on the ignition, all lamps
(except low-beam headlamp indicator lamp,
high-beam headlamp indicator lamp, and turn
signal indicator lamps unless activated) in the
instrument cluster come on. If a lamp in the
instrument cluster fails to come on when the
ignition is switched on, have it checked and
replaced if necessary. If a lamp in the
instrument cluster remains on after starting
the engine or comes on while driving, refer to
“Lamps in instrument cluster” (Y page 213).
If the SmartKey is left in starter switch
position 0 for an extended period of time, it
can no longer be turned in the starter switch.
In this case, the steering is locked. To unlock,
remove SmartKey from the starter switch and
reinsert.
The steering is locked when the SmartKey is
removed from the starter switch.
! If the SmartKey cannot be turned in the
starter switch, the vehicle battery may not
be sufficiently charged.
RCheck the vehicle battery and charge it
if necessary.
RGet a jump start.
Always remove the SmartKey from the
starter switch when the engine is not in
operation. This will help to prevent
accelerated vehicle battery discharge or a
completely discharged vehicle battery.
