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 š appears in th e m ain odometer
display field prior to the next suggested service.
Depending on operating conditions throughout the year,
the next service is calculated and displayed in days
š or distance 9 remaining.The symbols 9 or ´ indicate the type of service
to be performed:
9Service A
´Service B
The message is displayed for approximately 10 seconds
when turning the key in steering lock to position 2, or
while driving when reaching the service warning
threshold. It can be canceled manually by pressing
button (1).
Once the suggested term has passed, the message plus
symbol 9 or š, preceded by a – (minus symbol)
blinks for approx. 30 seconds and a signal sounds every
time when turning the key in steering lock to position 2.
The FSS display can also be called up for approx.
10 seconds with display illuminated by pressing
button (1) twice within 1 second.
Following a completed
A or B service the Mercedes-Benz Center sets the
counter to 10 000 miles (Canada: 15 000 km) and
365 days.

cluster displayPractical hints Car care Index Notes:
If the symbols : and I are continuously
illuminated after pressing button (1) twice and there is
no change in the odometer display field or the low
engine oil level warning lamp comes on, a malfunction
has occurred to the system. Perform the engine oil level
check with the dipstick.
If no oil leaks are noted continue to drive to the nearest
Mercedes-Benz Center to have the system checked.
Observe the engine oil temperature gauge.
Fuel consumption gauge
While driving, instantaneous fuel consumption is
indicated in miles per gallon (mpg), or in Canada liters
per 100 kilometers (l/100 km).
With the engine switched off, the needle reads “0”.
Due to system design, minimum consumption is
indicated at idle speed.Engine oil temperature gauge
Normal operating engine oil temperatures are from
175 F (80 C) to 250 F (120 C).
During severe operating conditions and stop-and-go
traffic, the engine oil temperature may rise close to the
red marking.
The engine should not be operated with the engine oil
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
When the engine oil temperature is close to the red
marking, relieve the load on the engine by decreasing
vehicle speed to lower engine oil temperature.
Once the engine oil temperature returns to the normal
temperature range, the engine oil level should be
checked. See page 82 or 221.
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.

Important!
The roll bar is intended to be a safety enhancement to
the other features designed into the vehicle. No system
in any vehicle can eliminate the possibility of serious
injury or fatality in an accident. Properly fastened seat
belts and child restraints must be used!
Wa r n i n g
This vehicle is a two occupant vehicle. The rear
storage area should never be used by any persons.
Raising or lowering of t he roll bar cou ld i nju re rear

Notes:
A warning sounds when the driver’s door is opened
while the key is in steering lock position 1 or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster.Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the key from the steering
lock. Do not leave the key in steering lock position 0.
