The electronic main key has an integrated radio
frequency and infrared remote control, plus removable
mechanical key.
The remote control (1) operates all locks on the vehicle.
The mechanical key (2) works only in the driver’s door,
trunk, and storage compartment locks.When using the mechanical key (2) for lock operations,
it can be removed by sliding it out of the remote control.
To do so, move locking tab (3) to the right and slide the
mechanical key (2) in direction of arrow (4).
The remote control transmitter is located in the
electronic main key.
The infrared receivers are located in the door handles.
Notes:
Remove the mechanical key from the electronic main
key when using valet parking service. To prevent access
to trunk or storage compartments lock them separately
and retain the mechanical key.

features through the multifunction steering wheel
should only be done by the driver when traffic and
road conditions permit it to be done safely.
Programming individual settings in the system can
only be made while the vehicle is at standstill.

cluster displayPractical hints Car care Index Flexible service system (FSS)
(service indicator)
The FSS permits a flexible service schedule that is
directly related to the operating conditions of the
vehicle.
The symbol 9 or ½ appears together with a
message in the multifunction indicator prior to the next
suggested service. Depending on operating conditions
throughout the year, the next service is calculated and
displayed in days or distance remaining.The message is displayed for approx. 10 seconds when
turning the electronic key in steering lock to position 2,
or while driving when reaching the service warning
threshold.
The symbols and messages indicate the type of service
to be performed:
9Service A
½Service B
One of the following messages will appear in the display
(e.g. Service A):
“SERVICE A – IN xx DAYS”
“SERVICE A – IN xx MILES” (Canada: KM)
“SERVICE A – EXCEEDED BY xx DAYS”
“SERVICE A – EXCEEDED BY xx MILES” (Canada: KM)
“SERVICE A – DUE NOW”
The next service due date is displayed either in days or
in miles, depending on your driving style.
Once the suggested service term has passed, the symbol
and message appear for approx. 30 seconds and a signal
sounds every time when turning the electronic key in
steering lock to position 2.

The service indicator disappears automatically after
30 seconds or if button J on the instrument cluster is
pressed.
Calling up service indicator manually:
Turn the electronic key in steering lock to position 1.
Call up the trip odometer and main odometer by
pressing button è or ÿ on the multifunction
steering wheel until the display appears. See page 92.
Press button j or k until the FSS indicator
appears.
Pressing the è or ÿ button displays the next or
previous system.
Important!
The FSS indicator is not an engine oil level indicator.
See page 112 for engine oil level indicator.Notes:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach operating normal temperature, reduce the interval
between services.

cluster displayPractical hints Car care Index Following a completed A or B service the
Mercedes-Benz Center sets the counter mileage to
10 000 miles (Canada: 15 000 km) and 365 days.
The counter can also be set by any individual. To do so:
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 until the FSS indicator
appears.
Press button Jon the instrument cluster for
approximately 2 seconds.The multifunction display will show the question:
“DO YOU WANT TO RESET SERVICE INTERVAL? –
CONFIRM BY PRESSING R”
Press button J on the instrument cluster again, and
hold until a signal sounds. The message “SERVICE
INTERVAL HAS BEEN RESET” appears in the
multifunction display.
The new service indicator is displayed with the reset
distance of 10 000 miles (Canada 15 000 km).
If the FSS counter was inadvertently reset, have a
Mercedes-Benz Center correct it.
However you choose to set your reference numbers, the
scheduled services as posted in the Service Booklet
must be followed to properly care for your vehicle.

113 Engine oil level indicator
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index One of the following messages will subsequently appear
on the indicator:
“ENGINE OIL LEVEL – O.K.”
No oil needs to be added.
“ENGINE OIL LEVEL – ADD 1.0 QUART”
(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”
(Canada: 1.5 L)
“ENGINE OIL LEVEL – ADD 2.0 QUART”
(Canada: 2.0 L)
See page 251 for instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The message “PERF. SERV. ON TIME” (perform service
[engine oil level check] on time) will be displayed if a
proper oil level check cannot be performed. The engine
oil level check can be repeated after a short time.Perform the engine oil level check with the dipstick, if it
cannot be completed via the multifunction display.
See page 251.
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.
Note:
See malfunction and warning messages on page 231
and page 241 if an engine oil level indicator appears on
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.
