172 OperationEngine compartment
Closing
Let the hood drop from a height of ap-
proximately 1ft (30cm).
The hood will lock audibly.
Check to make sure that the hood is
fully closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when
the vehicle is new
the vehicle is driven frequently at high-
er engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Checking engine oil level
When checking the oil level the vehicle
must
be parked on level ground
be at normal operating temperature
have been stationary for at least five
minutes with the engine turned off
Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature 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 the fire department.Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition 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
Warning!
G
Be careful that you do not close the hood on
anyone.

Maintenance
Maintenance
We strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.1Knob
2Display in the speedometer
Approximately one month before your next
service is due, the type of service is indi-
cated in the speedometer display2:

Minor service (A)
´
Major service (B)Depending on operating conditions
throughout the year, one of the following
service symbols is also shown:
9
1000 Calculated distance remain-
ing, e. g. service in
1000 miles (km)
š
10 Calculated remaining time in
days, e. g. service in 10 days
Clearing the service indicator
The service indicator is automatically
cleared after 10 seconds when you switch
on the ignition or when reaching the ser-
vice treshold while driving. You can also
clear it yourself.
Press knob1.iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short distance trips will
lengthen the interval between services.

Calling up the service indicator
Within 1 second press knob1
(page 185) twice.
The service symbol and the service
deadline appear in the display2.
Resetting the service indicator
In the event that the service on your vehi-
cle is not carried out by an authorized
Mercedes-Benz Center, you can reset the
service indicator yourself.
Switch ignition on and immediately
press knob1 (
page 185) twice with-
in 1 second.

is displayed.
Within 10 seconds turn key in steering
lock to position0.
Press and hold knob1 while turning
key in steering lock to position2 again.

iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center
correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-Benz Limited Warranty.
If the battery is disconnected, the days
of disconnection will not be included in
the count shown by the service indica-
tor. To arrive at the true service dead-
line, you will need to subtract these
days from the days shown in the ser-
vice indicator.
Do not confuse the service indicator
with the engine oil level indicator

199 Practical hints
What to do if …?
Problem
Possible cause
Suggested solution
?
The yellow “CHECK ENGINE”
malfunction indicator lamp
comes on while driving.
There is a malfunction in:
The fuel management system
The ignition system
The emission control system
Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.
Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the passenger
compartment near the engine hood
release.
The fuel cap is not closed tight.
Check the fuel cap.
Your gas tank is empty.
After refuelling, start the engine three
or four times in succession.
The limp-home mode is canceled. You do
not need to have your vehicle checked.
<
The red seat belt warning lamp
blinks for a brief period after
starting the engine.
The warning lamp reminds you to fasten seat
belts.
Fasten your seat belt.
