3Side impact airbag
The side impact airbags are located in the doors.
The most effective occupant restraint system yet
developed for use in production vehicles is the seat belt.
In some cases, however, the protective effect of a seat
belt can be further enhanced by an airbag.
In conjunction with wearing the seat belts, the driver
and front passenger airbags can provide increased
protection for the driver and front passenger in certain
frontal impacts exceeding preset thresholds. Door mounted side impact airbags can provide increased
protection to belted front passengers on the impacted
side of the vehicle in side impacts exceeding its preset
threshold.
Important!
The operational readiness of the airbag system is
verified by the indicator lamp SRS in the instrument
cluster when turning the electronic key in steering lock
to position 1 or 2. If no fault is detected, the lamp will go
out after approximately 4 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 4 seconds or if it comes on thereafter,
a malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, Emergency tensioning
devices, seat sensor.

63 Restraint systems
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Initially, when the electronic 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).
Have the system checked at your authorized
Mercedes-Benz Center immediately.
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 front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.Front airbags
The driver and front passenger front airbags are
designed to activate only in certain frontal impacts
exceeding a preset threshold.
The front passenger airbag deploys only if the front
passenger seat is occupied and the indicator lamp on
the center console is not illuminated.
Note:
Objects heavier than 20 lbs (9 kg) on the front
passenger seat can appear to the SRS to indicate the
presence of an occupant in that seat which causes the
passenger front airbag to deploy in a crash exceeding
the appropriate threshold.
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
unnecessarily which could also result in injury.

Engine oil level indicator
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after turning
off the engine, allowing for the oil to return to the oil
pan.Turn the electronic key in steering lock to position 2.
To call up the trip odometer and main odometer, press
button è or ÿ on the multifunction steering
wheel until the display appears. See page 88.
Press button j or k on the multifunction
steering wheel repeatedly until the “MEASUREMENT
CORRECT – ONLY IF VEH. LEVEL” engine oil level
indicator appears. This indicator is only a reminder.
Measurement can be cancelled by pressing button j
or k if the vehicle is not parked on level ground. An
incorrect reading will be displayed if you do not cancel
the measurement. Move the vehicle to level ground and
measure again.
The electronic key in steering lock is not in position 2 if
the “ENGINE OIL LEVEL – SWITCH ON IGNITION”
message appears.
The “ENGINE OIL LEVEL – MEASURING NOW”
message is displayed after approximately 3 seconds.

Switching on and off
Press the control knob .
The radio is switched off when the ignition key is turned
to position 0 or removed from the ignition. The radio is
switched on again when the ignition key is turned to
position 1 or 2.
Note:
The radio can also be switched on even if the ignition
key is not inserted, but will switch itself off
automatically after one hour to conserve vehicle battery
power.
Adjusting the volume
Turn the control knob - turning the knob clockwise will
increase the volume, counterclockwise will decrease the
volume.Audio functions
The AUD key is used to select the BASS, TREBLE and
BALANCE functions. Settings for bass and treble are
stored separately for the cassette and CD modes. Tone
level settings are identified by the vertical bars. The
center (flat) setting is shown by one longer bar in the
center of the display.
Bass
Press the AUD key repeatedly
until “BASS” appears in the
display.
Treble
Press the AUD key repeatedly
until “TREBLE” appears in the

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.
