The service indicator disappears automatically after
30 seconds or if button J o n t he instrum ent clu ster 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 driv ing in wh ich th e engine d oes not
reach operating normal temperature, reduce the interval
between services.

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 stopping
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 92.
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 recorded 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.

Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE/CCMC class) and filling quantity, see
page 317.
•Check engine coolant anticorrosion/antifreeze
concentration.
•Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent/antifreeze
which is formulated for below freezing temperatures
see page 259.
•Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or of the electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and / or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
For driving instructions with snow chains, see page 210.
Deep water
Caution!
Do not drive t hrou gh f lood ed a rea s or water of u nk nown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
Block heater (Canada only)
The engine is equipped with a block heater.
The electrical cable may be installed at your authorized
Mercedes-Benz Center.

ENGINE OIL LEVEL
1 The engine oil level must be checked immediately. See Engine oil
level indicator on page 112
2 There is no oil in the engine. There is a danger of engine damage.3 There is a risk of damaging the engine or catalytic converter. The
engine oil level must be checked immediately. See Engine oil level
indicator on page 112.
4 The engine oil level has dropped to a critical level.
Check the engine oil level immediately. See Engine oil level
indic ato r o n p age 112 a nd check the eng ine for vis ible lea ka ge (lo ss
of oil).
5 The measuring system is malfunctioning.
6 It may be that there is water in the engine oil. Have the engine oil
che cked.
When the “ENGINE OIL LEVEL – CHECK LEVEL”
message appears while the engine is running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The engine oil level warnings should not be ignored.
Extended driving with the symbol displayed could
result in serious engine damage that is not covered by
the Mercedes-Benz Limited Warranty.

Hood
Wa r n i n g !
To help prevent personal injury, stay clear of
moving parts wh en t he hood is open and th e 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.
