Other display messages
If there is excess engine oil with the engine
at normal operating temperature, a signal
sounds and the following message will
blink in the display:
HIThe oil level is too high.
Have excess oil siphoned or drained
off. Contact your authorized Mer-
cedes-Benz Center.!If the message

) blinks and a signal
sounds, add oil according to amount
displayed.

177 Operation
Engine compartment
TheI symbol flashes in the
speedometer display if a proper oil level
check cannot be performed.
If engine is at normal operating
temperature, wait five minutes before
repeating check procedure.

If engine is not yet at normal operating
temperature, wait 30 minutes before
repeating check procedure.See the “Practical hints” section
(
page 199) if the low engine oil level
warning lamp in the instrument cluster
comes on.
Checking engine oil level with the oil
dipstick
When checking the oil level the vehicle
must


be parked on level ground


be at normal operating temperature


have been stationary for at least five
minutes with the engine turned off
!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.
iPerform the engine oil level check with
the dipstick if it cannot be completed
via the speedometer display
(page 177).
In this case we recommend that you
have the system checked at a
Mercedes-Benz Center.
iIf the: andI symbols are
continuously illuminated after pressing
button1 (
page 176) twice, and if
there is no change in the speedometer
display 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 (page 177).
Visually check for oil leaks. If no obvi-
ous oil leaks are noted, drive to the
nearest authorized Mercedes-Benz
Center to have the system checked.
iThe engine oil level can be checked by
either the oil dipstick or via the
speedometer display (SLK 320,
SLK 32 AMG only) in the instrument
cluster (
page 176). The amount of
engine oil needed is shown more
precisely in the speedometer display.

190 OperationMaintenance
MaintenanceWe strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.1Knob
2Display in the speedometer
Approximately one month before your next
service is due, the type of service is indi-
cated in the speedometer display2:
9Minor service (A)
´Major service (B)
Depending on operating conditions
throughout the year, one of the following
service symbols is also shown:
9 1000 Calculated distance remain-
ing, e. g. service in
1000 miles (km)š 10 Calculated remaining time in
days, e. g. service in 10 days
Clearing the service indicator
The service indicator is automatically
cleared

after ten seconds when you switch on
the ignition or when reaching the
service threshold while driving


after 30 seconds, once the suggested
service term has passed
You can also clear it yourself.

Press knob1.iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short distance trips will
lengthen the interval between services.

191 Operation
Maintenance
Service term exceeded
If you have exceeded the suggested
service term:

the9 or´ appears in the
display2 for 30 seconds and a signal
sounds after switching on the ignition.


it is preceded by a “-” (minus symbol)
The Mercedes-Benz Center will reset the
service indicator following a completed
service.
Calling up the service indicator
Within one second press knob1
(page 190) twice.
The service symbol and the service
deadline appear in the display2.
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 (key in steering lock
position 2) and immediately press
knob1 (
page 190) twice within
1 second.
The present status for days or distance
is displayed.

Within ten seconds turn key in steering
lock to position0.

Press and hold knob1 while turning
key in steering lock to position2 again.
The present status for days and dis-
tance is displayed once more.
Continue to hold knob1 until you
hear a signal.

Release knob1.
The service indicator now displays the
reset interval.
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 proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the Mer-
cedes-Benz Limited Warranty.
If 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:.

screw
3Union nut
4Electrical plug

Open flap1 on air pump.

Pull out electrical plug4 and air hose
with pressure gauge2.

Screw union nut3 with air hose2 on
to the tire valve.

Insert electrical plug4 into vehicle
cigarette lighter socket.

Turn key in steering lock to position1
(page 29).

PressI on the electric air pump switch.
The electric air pump should now
switch on and inflate the tire.
After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose and the union nut can become hot
during inflation. Please exercise appropri-
ate caution.

If this tire pressure is not attained, turn
off the electric air pump, detach the air
hose from the tire valve, and again
drive vehicle back and forth very slowly
approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.

Inflate the tire again.

Press0 on the electric air pump
switch.

Turn key in steering lock to position0.
The electric air pump should now be
switched off.
Warning!
G
Observe safety instructions on air pump la-
bel.
!Do not exceed the maximum pressure
of 36 psi (2.5 bar).
!Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.

242 Practical hintsFlat tire
Unscrew the valve cap from tire
valve7.

Screw filler hose onto tire valve7.

Insert electrical plug4 into vehicle
cigarette lighter socket.

Turn key in steering lock to position1
(page 29).

PressI on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose can become hot during inflation.
Please exercise appropriate caution.

If this tire pressure is not attained, turn
off the electric air pump, detach the fill-
er hose from the tire valve, and drive
vehicle back and forth very slowly ap-
proximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.

Unscrew the air pump’s air hose5
from flange6 of the TIREFIT contain-
er.

Screw air hose5 onto tire valve7
and inflate the tire again.

After attaining a tire pressure of 26 psi
(1.8 bar), press0 on electric air pump
switch8.
The electric air pump should now be
switched off.

Turn key in steering lock to position0
(page 29).
iIf sealant has leaked out, let it dry. You
can then peel it off.!Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
If a tire pressure of 26 psi (1.8 bar) is not at-
tained, tire is too severely damaged for
TIREFIT to provide a reliable tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.
