CL 63 AMG1Filler cap

Unscrew filler cap1 from filler neck.

Add engine oil as required. Be careful
not to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.

Screw filler cap1 back on filler neck.

Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the automatic transmission.Active Body Control (ABC) fluid level
Regular fluid level check is not required. If
you notice fluid leaks or malfunction mes-
sages in the multifunction display, have an
authorized Mercedes-Benz Center check
the ABC-system.

Excess oil must be siphoned or drained off.
It will cause damage to the engine and emission
control system not covered by the
Mercedes-Benz Limited Warranty.

563 Operation
Tires and wheels
Tread depth
Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths of less
than
1/8in (3 mm).
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately 1/16in (1.6 mm), at which point the
tire is considered worn and should be re-
placed.
Recommended minimum tire tread depth:


Summer tires
1/8in (3 mm)


Winter tires
1/6in (4 mm)
1TWI (T

The treadwear indicator appears as a solid
band across the tread.Storing tires

Warning!
G
Although the applicable federal motor safety
laws consider a tire to be worn when the
treadwear indicators (TWI) become visible at
approximately
1/16in (1.6 mm), we recom-
mend that you do not allow your tires
to wear down to that level. As tread depth
approaches
1/8in (3 mm), the adhesion
properties on a wet road are sharply
reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
!
Keep unmounted tires in a cool, dry place
with as little exposure to light as possible. Pro-
tect tires from contact with oil, grease and gaso-
line.
!
Never use a round nozzle to power wash
tires. The intense jet of water can result in dam-
age to the tire.
Always replace a damaged tire.

Stop Vehicle!
You have started driving although the vehi-
cle level is still too low.
The vehicle is raised. The ABC message
goes out after a few seconds.

Stop your vehicle as soon as it is safe to do
so.

Engage the electronic parking brake
(page 412).

Wait until the message disappears from the
multifunction display.
You may then drive off.
The vehicle is losing oil.
The ABC message is continuously shown.

Stop your vehicle as soon as it is safe to do
so.

Engage the electronic parking brake
(page 412).

Call Roadside Assistance.

Notify an authorized Mercedes-Benz Center.

Engine Oil Level Low
Stop Vehicle
Turn Engine Off
CL 600 and CL 65 AMG only:
There is no oil in the engine. There is a dan-
ger of engine damage.

Carefully bring the vehicle to a halt as soon
as it is safe to do so in a safe location.

Engage the electronic parking brake
(page 412).

Turn off the engine.

Add engine oil (
page 557) and check the
engine oil level (page 554).

What to do if …?
When the message “Check Engine Oil Level
at Next Refueling” (CL 550 and
CL 63 AMG) or “Check Engine Oil Level
(Add 1 quart). (Canada:1Liter)” (CL 600
and CL 65 AMG) appears while the engine
is running and at operating temperature,
the engine oil level has dropped to approx-
imately the minimum level.When this occurs, the warning is at first in-
termittent and then remains on if the oil
level drops further.
Visually check for oil leaks. If there are no
obvious oil leaks, drive to the nearest ser-
vice station to refill engine oil to the re-
quired level with an approved oil.For information on approved engine oils,
refer to the Factory Approved Service
Products pamphlet (USA only) or contact
an authorized Mercedes-Benz Center.Display

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.
