Te ch n i c a l

cluster displayPractical hints Car care Index 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.

The counter can also be set by any individual. To do so:
1. Turn key in steering lock to position 2.
2. Within 1 second 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 approximately 10 seconds a signal sounds, and
the display shows 10 000 miles
(Canada: 15 000 km) for approximately 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. 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.
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.

cluster displayPractical hints Car care Index Checking engine oil level
(SLK 320 and SLK 32 AMG only)
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after turning
off the engine, allowing for the oil to return to the oil
pan.
Turn electronic key in steering lock to position 2 and
wait until the symbols : and I appear in the
odometer display field.Within 1 second press left button on the instrument
cluster twice.
The following messages are available:
“OK”
“-1.0 Q” (Canada: -1.0 L)
“-1.5 Q” (Canada: -1.5 L)
“-2.0 Q” (Canada: -2.0 L)
If the message “-2.0 Q” (Canada: -2.0 L) blinks and a
signal sounds, add oil according to amount displayed.
See page 197 for instructions on adding engine oil.
“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.
Notes:
If the symbols : and I are continuously
illuminated after pressing left button on the instrument
cluster 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.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.
