The following system components are monitored or
undergo a selfcheck: crash-sensor(s), airbag ignition
circuits, seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the key is turned from steering lock
position 0 to positions 1 or 2, malfunctions in the crash-
sensor are detected and indicated (the “SRS” indicator
lamp stays on longer than 4 seconds or does not come
on). In the operational mode, after the indicator lamp
has gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and passenger seat belt buckle harnesses, and
low voltage in the entire system are detected and
indicated.
Have the system checked at your authorized
Mercedes-Benz Center immediately.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized Mercedes-
Benz Center immediately to have the system
checked; otherwise the “SRS” may not be activated
when needed in an accident, which could result in
serious or fatal injury, or it might deploy
unexpectedly and unnecessary which could also
result in injury.

Hood
Wa r n i n g !
To help prevent personal injury, stay clear of
moving parts when the hood is open and the engine
is running. Be sure the hood is properly closed
before driving. When closing hood, use extreme
caution not to catch hands or fingers.The radiator fan may continue to run for
approximately 30 seconds or even restart after the
engine has been turned off. Stay clear from fan
blades.
The engine is equipped with a transistorized
ignition system. Because of the high voltage it is
dangerous to touch any components (ignition coils,
spark plug sockets, diagnostic socket) of the
ignition system
• with the engine running,
• while starting the engine,
• if ignition is “on” and the engine is turned
manually.If you see flames, steam or smoke coming from the
engine compartment, or if the coolant temperature
gauge indicates that the engine is overheated, do
not open the hood. Move away from vehicle and do
not open the hood until the engine has cooled. If
necessary, call a fire department.
