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.
The standard display of the control sys-
tem appears (
page 114).

Press button

on the mul-
tifunction steering wheel until the FSS
indicator with the service symbol

or
´
and the service deadline ap-
pears in the multifunction display.

Press the reset knob to the left in the
instrument cluster for about four sec-
onds.
This message appears in the multifunc-
tion display:Do you want to reset service inter-
val?
To confirm press button

To confirm, hold down the reset knob
until you hear a signal.
The service indicator now displays the
reset interval.
iIf 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
:
.
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 the proper service
as called for by the FSS will cause the
FSS to incorrectly determine the next
service interval which will result in en-
gine damage not covered by the
Mercedes-Benz Limited Warranty.

Possible cause
Suggested solution
ESP
Defective!
Visit workshop!
The ESP is deactivated because of a mal-
function or interrupted power supply. The
ABS may still be operational.

With the vehicle stationary and the en-
gine running, turn the steering wheel
completely to the left and then to the
right to synchronize the ESP.
If the ESP message does not go out:

Continue driving with added caution.

Visit an authorized Mercedes-Benz
Center as soon as possible.
Failure to follow these instructions in-
creases the risk of accident.
:
Engine oil level
Stop, engine off!
There is no oil in the engine. There is a
danger of engine damage.

Carefully bring the vehicle to a halt as
soon as possible.

Turn off the engine.

Add engine oil.

When the
Engine oil – Visit workshop!

message appears while the engine is run-
ning and at operating temperature, the en-
gine 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.

Suggested solution
:
Engine oil level
Reduce oil level!
You have added too much engine oil.
There is a risk of damaging the engine or
the catalytic converter.

Have oil siphoned. Observe all legal re-
quirements with respect to its dispos-
al.
Engine oil
Visit workshop!
The engine oil has dropped to a critical
level.

Check the engine oil level
(page 254) and add oil as required.

If you must add engine oil frequently,
have the engine checked for possible
leaks.
There is water in the oil.

Have the oil checked.

The measuring system is malfunctioning.

Have the measuring system checked
by an authorized Mercedes-Benz Cen-
ter.!The engine oil level warnings should
not be ignored. Extended driving with
the symbol displayed could result in se-
rious engine damage that is not cov-
ered by the Mercedes-Benz Limited
Warranty.

Steering oil
Visit workshop!
The steering gear oil level is too low.
There is a danger of steering gear dam-
age.

Have the system checked by an autho-
rized Mercedes-Benz Center.
Warning!
G
If the level of steering gear oil in reservoir is
too low, the steering power assistance could
fail. Much greater effort will then be needed
to turn the steering wheel.
Do not add steering oil without checking the
steering system.
Do not drive the vehicle. Have the system
checked at your authorized Mercedes-Benz
Center as soon as possible.

355 Technical data
Fuels, coolants, lubricants, etc.
Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.
If the coolant level is low, water and MB
Anticorrosion /Antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
Please make sure that the mixture is in ac-
cordance with label instructions.The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase boil-over protec-
tion. You should have it replaced every 15
years or 150 000 miles (250 000 km),
whichever comes first.
Coolant system design and coolant used
stipulate the replacement interval. The
above replacement interval is only applica-
ble if MB 325.0 anticorrosion/antifreeze
solution or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level.
