Coolant temperature gauge
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.Outside temperature indicator
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).
Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
Wa r n i n g !
• Driving when your engine is badly overheated
can cause some fluids which may have leaked
into the engine compartment to catch fire. You
could be seriously burned.• Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it.Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.

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 the main 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.

1. Turn key in steering lock to position 2.
2. Within 4 seconds press button (1) twice.
3. The present status for days or distance is displayed.
Within 10 seconds turn key in steering lock to
position 0.
4. Press and hold button (1), while turning key in
steering lock to position 2 again. The present status
for days or distance is displayed once more.
Continue to hold button (1).
After approx. 10 seconds a signal sounds, and the
display shows 10 000 miles (Canada: 15 000 km) for
approx. 10 seconds.
5. Release button (1).
If the FSS counter was inadvertently reset, have a
Mercedes-Benz Center correct it.Note:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the kind
of vehicle operation. For example driving at extreme
speeds, and cold starts combined with short distance
driving in which the engine does not reach normal
operating temperature, reduce the interval between
services.
Model SL 500
The FSS allows for distances between 10 000 miles
(Canada: 15 000 km) and 20 000 miles (Canada:
30 000 km), or from 365 to 730 days between services.
Model SL 600
The FSS allows for distances between 10 000 miles
(Canada: 15 000 km) and 16 000 miles (Canada:
25 000 km), or from 365 to 730 days between services.
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.

If the message “-2.0 Q” (Canada: -2.0 L) blinks and a
signal sounds, add oil to upper (max) mark of the
dipstick.
“HI”
The message “HI” blinks and a signal sounds.
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could
cause damage to engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The symbol I flashes in the odometer display field if
a proper oil level check cannot be performed.
The oil level check can be repeated after a short time.
Perform the oil level check with the dipstick, if it cannot
be completed via the odometer display field.
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.

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 222.
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.
