Introduction
We want you to enjoy your Mercedes-Benz automobile. Vehi-
cle safety and operational reliability are two very important
factors and to maintain them, a certain amount of service and
maintenance is necessary. The Mercedes-Benz Flexible Ser-
vice System calls for all the necessary maintenance required
for your engine.
We continuously strive to improve our product, and ask for
your understanding that we reserve the right to make changes
in the required periodic maintenance work which is required
for our vehicles.
The vehicle comes equipped with the Flexible Service System
(FSS) which evaluates engine temperature, oil level, vehicle
speed, engine speed, distance driven and the time elapsed
since your last service. It determines when your vehicle needs
service and alerts you well in advance. The next necessary
FSS service is indicated in the instrument cluster.
There are two types of scheduled services for your vehicle, a
(“minor” =) A-service, and a (“major” =) B-service.
Under normal circumstances the driven distance between ser-
vices is an average of approximately 12000 miles. Under
most circumstances, A and B-services will be called for by FSS
alternatively, i.e. A will follow B which will be followed by an
A-service.
Exception: A B-service will be followed by another B-service, if
the FSS calculates an oil change interval of 14 000 miles or
more.
Following each A or B-service your Mercedes-Benz Center will
reset the FSS counter. The next service is indicated in the
instrument cluster (see chapter “Flexible Service System” in
your Operator’s Manual).
Required service work which is not calculated by the FSS is
listed in the section “Additional Work to be Performed” (see
page 26).
Wear items such as, but not limited to, engine belts, brake
discs, brake pads, brake pad wear sensors, clutch discs and
clutch pressure plates are not covered by the maintenance
commitment.
A detailed listing of maintenance procedures performed are
contained in this booklet, starting on page 22.

Special Service Measures
Brake fluid should be replaced every two years, preferably in
the spring, see page 25. We recommend that you only use
brake fluid approved by Mercedes-Benz.
A reminder for the next scheduled brake fluid replacement is
affixed in the engine compartment.
Coolant should be checked for the proper concentration
before the start of the winter season (or once a year in hot
regions). Have the coolant (water/anticorrosion/antifreeze
mixture) replaced every three years, see page 25.
Dust filter should be replaced at the scheduled B service.
Under severe dust conditions, or with the Automatic Climate
Control frequently operating in the air recirculation mode, the
dust filter should be replaced correspondingly sooner.
Tire rotations should be performed in accordance with the
tire manufacturer’s recommendations. In addition, tire rota-
tion will be performed under the B-Service on an if necessary
basis. MBUSA recommends that you follow your tire manufac-
turer’s schedule for tire rotation, which are specific to the tires
installed as original equipment. Tire rotation performed at
other than a B-Service is not covered by the maintenance com-
mittment.
The performance of all scheduled service work is required
to maintain your vehicle in good operating condition and
is essential to keep your warranty valid. We strongly rec-
ommend that you have scheduled maintenance service as
well as all other repairs to your vehicle performed at an
authorized Mercedes-Benz Center because they are
equipped with the tools, instruments, literature, and
trained personnel necessary for the correct and proper
performance of these jobs.
Spare Parts/Operating Materials
We recommend only the use of Genuine Mercedes-Benz parts
for service and repairs, since they meet our specifications. It is
also important to only use fuels, lubricants and anticorrosion/
antifreeze coolant meeting factory specifications. Please refer
to the Factory Approved Service Products Booklet or see your
Mercedes-Benz Center for more information on this subject.

Routine Checks
In addition to the services, we recommend that you check the
following items regularly (for example, weekly or each time
you fill up) and prior to any long trip:
• Engine oil level – at regular intervals (such as every fuel
stop).
• Coolant level - Please refer to the Operator’s Manual for the
correct procedure to check the coolant level.
• Fluid level of brake system - If brake fluid has to be added,
see an authorized Mercedes-Benz Center to determine the
cause, e.g. leaks or worn brake pads.
• Windshield washing system - If the washer fluid level
drops below 1/3, the windshield washer fluid level warning
lamp will illuminate. Add washer fluid mixed with Mer-
cedes-Benz windshield washer solvent/concentrate, test
function and check wiper blades.
• Exterior lamps - check for proper function
Tire pressure – at least every other week.
Recommended Synthetic Motor Oil
Mercedes-Benz recommends only the use of MB approved syn-
thetic motor oil for all vehicles equipped with the Flexible Ser-
vice System (FSS) as of Model Year 1998.
Conventional petroleum based oils are not recommended for
vehicles equipped with the Flexible Service System.
Please refer to the Factory Approved Service Products Booklet
or see your Mercedes-Benz Center for more information on
selecting the proper motor oil for your vehicle.

Emission System Maintenance
The U. S. Environmental Protection Agency and, in California,
the Air Resources Board have certified that the emission con-
trol system of your vehicle meets exhaust emission standards
for 2002. This vehicle also complies with the Canadian Motor
Vehicle Emission Standards.
To be certain that the emission control system functions as
designed, regular maintenance is necessary for all compo-
nents of the vehicle which affect exhaust emission composi-
tion.
The vehicle owner is responsible for the regular maintenance
of the emission control system, as well as the use of premium
unleaded gasoline with an anti-knock index of at least 91
(displayed on the pump) in all models.
Refer to your Service and Warranty Information booklet and
Operator’s Manual for additional information.
Failure to properly maintain the emission system may result
in repairs not being covered by the emission systems war-
ranty.
Explanations of each maintenance job are given in numerical
order on page27.

Emission Control System Caution
Your Mercedes-Benz is equipped with both a three-way cata-
lyst and a closed loop oxygen sensor system to comply with
current exhaust emission regulations. Keep your vehicle in
proper operating condition by following our recommended
maintenance instructions as outlined.
The following has to be adhered to:
a. In all models, use only premium unleaded gasoline
with an anti-knock index of at least 91 (as displayed on
the pump). Damage to the engine could occur if premium
unleaded fuel is not used. Refer to the Operator’s Manual
for special precautions.
b. Leaded gasoline should not be used under any circum-
stances. Damage to the emission control components will
result.
c. The specified engine maintenance jobs have to be per-
formed completely and at the required intervals.
Correct ignition timing and properly functioning spark
plugs for instance are important for the service life of the
catalysts. Failure to properly perform the specified mainte-
nance jobs may adversely affect the emission control sys-
tem on the vehicle and reduce its service life.
d. The operation of the emission control system must not
be altered in any way. Alterations are not permissible by
law. In addition, alterations may result in damage to the
catalysts, increased fuel consumption and impaired engine
running conditions.
e. Irregular engine running conditions should be cor-
rected immediately by an authorized Mercedes-Benz
Center. Such irregular running conditions can influence
the proper function of the emission control system.
“CHECK ENGINE” indicator lamp in the instrument cluster: If
the lamp comes on when the engine is running, it indicates a
malfunction of the engine management system or emission
control system.
We recommend that you have the malfunction checked as
soon as possible.
