330 OperationMaintenanceClearing the maintenance service indicator
The maintenance service indicator is auto-
matically cleared after 30 seconds.
You can also clear it yourself.
Press reset buttonJ(
page 24) for
clearing the maintenance service indi-
cator.
The maintenance service indicator is
cleared and the standard display menu

(
page 122).
Maintenance service term exceeded
If you have exceeded the suggested main-
tenance service term, you will see the fol-
lowing message in the multifunction
display:Service A exceeded by XXXXX miles (km)
Service A exceeded by XXX days
Service A exceeded by X dayIn addition, a signal sounds when the mes-
sage appears.
Any authorized Mercedes-Benz Center will
reset the maintenance service indicator
following a completed maintenance
service.Calling up the maintenance service
indicator
Switch on the ignition (

service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator:.

360 Practical hintsWhat to do if …When the message
Add 1 qt.
(Canada:
1 liter
) engine oil when next
refueling (SLK 55 AMG) or
Check oil
level when next refueling (SLK 350)
appears while the engine is running and at
operating temperature, the engine oil level
has dropped to approximately the
minimum level.When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.
Visually check for oil leaks. If no obvious oil
leaks are noted, drive to the nearest ser-
vice station where the engine oil should be
topped to the required level with an ap-
proved oil specified in the Factory
Approved Service Products pamphlet.

SLK 55 AMG only:
The engine oil level is too low.

Add engine oil (
page 292) and check the
engine oil level (page 288).
Check oil level
when next refueling
SLK 350 only:
The engine oil level has dropped to
a critical level.

Check the engine oil level (
page 288) and
add engine oil as required (page 292).

If you must add engine oil frequently, have
the engine checked for possible leaks.
!The engine oil level warnings should
not be ignored. Extended driving with
the symbol displayed could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.

Stop, engine off
SLK 55 AMG only:
There is no oil in the engine. There
is a danger of engine damage.

Carefully bring the vehicle to a halt as soon
as possible.

Turn off the engine.

Add engine oil (

engine oil level (page 288).
Engine oil level
Visit workshop
SLK 55 AMG only:
The measuring system is malfunc-
tioning.

Have the measuring system checked by an
authorized Mercedes-Benz Center.
Engine oil level
Reduce oil level
SLK 55 AMG only:
You have added too much engine
oil. There is a risk of damaging the
engine or the catalytic converter.

Have oil siphoned or drained off.
Observe all legal requirements with respect
to its disposal.
Engine oil
Visit workshop
SLK 55 AMG only:
There may be water in the engine

Have the engine oil checked.

426 Technical dataFuels, coolants, lubricants, etc.In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Refer to the
Factory Approved Service Products pam-
phlet for a listing of approved product(s).
Follow directions on product label.
Do not blend any specific fuel additives
with fuel. This only results in unnecessary
costs and may be harmful to engine opera-
tion.
Damage or malfunction resulting from
poor fuel quality or from blending addition-
al fuel additives other than those tested
and approved by us for use on
Mercedes-Benz vehicles listed in the
Factory Approved Service Products
pamphlet are not covered by the
Mercedes-Benz Limited Warranty.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase boil-over protec-
tion. Refer to Maintenance Booklet for in-
formation on replacement intervals.Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products
pamphlet) are used to renew the coolant
concentration or bring it back up to the
proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. -22°F [-30°C]). If you
use a solution that is more than 55% anti-
corrosion/antifreeze (freeze protection to
approx. -49°F [-45°C]), the engine temper-
ature will increase due to the lower heat
transfer capability of the solution. There-
fore, do not use more than this amount of
anticorrosion/antifreeze.

Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. FSS evaluates en-
gine temperature, oil level, vehicle
speed, engine speed, distance driven
and the time elapsed since your last
maintenance service, and calls for the
next maintenance service accordingly.

Installed in the doors, these air bags
protect occupants during side impact
collisions exceeding a preset thresh-
old. Unlike normal side air bags,
head-thorax air bags are also designed
to provide protection for the head area.
Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
coolant temperature and fuel gauge.
Kickdown
Depressing the accelerator past the
point of resistance shifts the automatic
transmission down to the lowest possi-
ble gear. This very quickly accelerates
the vehicle and should not be used for
normal acceleration needs.
