Checking engine oil level with the oil
dipstick (CL 550 and CL 63 AMG)
To check the engine oil level with the oil
dipstick, do the following:
Open the hood (
page 553).
Example illustration from CL 5501Oil dipstick
2Upper mark
3Lower mark
Pull out oil dipstick1.

Wipe oil dipstick1 clean.

Fully insert oil dipstick1 into the dip-
stick guide tube.

Pull out oil dipstick1 again after ap-
proximately 3 seconds to obtain accu-
rate reading.
The oil level is correct when it is between
lower mark3 (min.) and upper mark2
(max.) mark of the oil dipstick.

If necessary, add engine oil.
For adding engine oil (
page 557).
For more information on engine oil, see the
“Technical data” section (page 733) and
(
page 736).
For more information on messages in the
multifunction display concerning engine
oil, see the “Practical hints” section
(page 622).Adding engine oil
i
CL 550 only:
The filling quantity between the upper and lower
marks on the oil dipstick is approximately
2.1 US qt. (2.0 l).
i
AMG vehicles only:
The filling quantity between the upper and lower
marks on the oil dipstick is approximately
1.6 US qt. (1.5 l).
!
Only use approved engine oils and oil filters
required for vehicles with Maintenance System.
For a listing of approved engine oils and oil fil-
ters, refer to the Factory Approved Service
Products pamphlet (USA only) in your vehicle
literature portfolio, or contact an authorized
Mercedes-Benz Center.
Using engine oils and oil filters of specification
other than those expressly required for the Main-
tenance System, or changing of oil and oil filter
at change intervals longer than those called for
by the Maintenance System will result in engine
or emission control system damage not covered
by the Mercedes-Benz Limited Warranty.

592 OperationMaintenanceWe strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Center, in accordance with
the Maintenance Booklet at the times
called for by the maintenance service indi-
cator.Maintenance service indicator
message
The maintenance service indicator mes-
sage will notify you when the next mainte-
nance service is due.
Starting approximately 1 month before the
next maintenance service is due, one of
the following messages will appear in the
multifunction display while you are driving
or when you switch on the ignition
(example service A):
“Next Service A in XXX miles (km)”
“Next Service A in XX days”
“Service A Due”The maintenance services will be indicated
by showing a service type A through type H
in the multifunction display. Types A
through H are classified based on estimat-
ed time needed to perform the mainte-
nance service, ranging
from “Service A”
(approximately 1 hour)
to “Service H”
(approximately 8 hours)
Refer to Maintenance Booklet for a listing
of maintenance services and intervals they
need to be performed at.
!
Failure to have the vehicle maintained in ac-
cordance with the Maintenance Booklet and
maintenance service indicator at the designated
times/mileage will result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
i
The Maintenance System in your vehicle
tracks distance driven and the time elapsed
since the last maintenance service and calcu-
lates other maintenance service work required.

Service
See Oper. Manual
CL 600 and CL 65 AMG only:
The brake system sensors are malfunction-
ing. The brake system continues to function
normally with full brake force boost.

Continue driving with added caution.

Have the system checked at an authorized
Mercedes-Benz Center as soon as possible.
(USA only)(Canada only)
Check
Brake Pad Wear
The brake pads have reached their wear
limit.

Have the brake pads replaced as soon as
possible.
!
Brake pad thickness must be visually
checked by a qualified technician at the intervals
specified in the Maintenance Booklet.

736 Technical dataFuels, coolants, lubricants, etc.Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System. For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet (USA
only), or contact an authorized
Mercedes-Benz Center.
Engine oil additivesAir conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or chang-
ing of oil and oil filter at change intervals longer
than those called for by the Maintenance System
will result in engine or emission control system
damage not covered by the Mercedes-Benz Lim-
ited Warranty.
Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.
!
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from blending
oil additives are not covered by the
Mercedes-Benz Limited Warranty.
!
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!
G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere.
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement inter-
val.

739 Technical data
Fuels, coolants, lubricants, etc.
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 re-
placement interval.
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 are used to
renew the coolant concentration or bring it
back up to the proper level.
For information on other Mercedes-Benz
approved products of equal specification,
refer to the Factory Approved Service
Products pamphlet (USA only) or contact
an authorized Mercedes-Benz Center.To provide important corrosion protection,
the solution must be at least 50% anticor-
rosion/antifreeze (equivalent to freeze
protection to approximately -35°F
[-37°C]). If you use a solution that is more
than 55% anticorrosion/antifreeze (freeze
protection to approximately -49°F
[-45°C]), the engine temperature will in-
crease due to the lower heat transfer capa-
bility of the solution. Therefore, do not use
more than this amount of anticorrosion/
antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze
should be used to bring it up to the proper
level (have cooling system checked for
signs of leakage).
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Center.Anticorrosion/antifreeze
Your vehicle contains a number of alumi-
num parts. The use of aluminum compo-
nents in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifical-
ly formulated to protect the aluminum
parts. Failure to use such anticorrosion/
antifreeze coolant will result in a signifi-
cantly shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
MB 325.0 Anticorrosion/Antifreeze agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Center for service.
