2006 MERCEDES-BENZ C55AMG warning

420 Practical hints
Fuses
Fuses are designed to protect the electri-
cal circuits in your vehicle from a short cir-
cuit. If a fuse is blown, the component(s)
and systems secured by that fuse will stop
operating.
The following aids are available to help you
replace fuses (
page 420):

Fuse chart

Spare fuses

Fuse extractor
The electrical fuses are located in different
fuse boxes:

Main fuse box in passenger
compartment (
page 421)

Fuse box in engine compartment
(
page 421)

Fuse box in trunk (page 422)
Aids for replacing fuses
Fuse chart
The fuse chart is located in the main fuse
box in the passenger compartment
(
page 421). The amperages of the fuses
are also given there.
Spare fuses
Spare fuses are located in the vehicle tool
kit in the trunk (
page 380).
Fuse extractor
The fuse extractor is located in the fuse
box cover in the trunk (
page 422).
Warning!G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question. Using other fuses may cause an
overload leading to a fire, and/or cause
damage to electrical components and/or
systems.
!
Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Center.
!
Keep the fuse boxes free by contamina-
tion and wetness. Otherwise, electrical
parts or systems could be damaged.

437 Technical data
Fuels, 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 (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet, or con-
tact an authorized Mercedes-Benz Center.
Engine oil additives
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.
Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air
conditioning system.
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. An
authorized Mercedes-Benz Center will
provide you with additional information.
!
Using engine oils and oil filters of
specification other than those express-
ly required for the Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles), or changing of oil and oil filter at
change intervals longer than those
called for by the Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles) will result in engine damage not
covered by the Mercedes-Benz Limited
Warranty.
Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles) recommendations for scheduled
oil changes. Failure to do so will result
in engine damage not covered by the
Mercedes-Benz Limited Warranty.
Warning!G
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 Mainte-
nance Booklet for replacement interval.

438 Technical data
Fuels, coolants, lubricants, etc.
Premium unleaded gasolineGasoline additives
A major concern among engine
manufacturers is carbon build-up caused
by gasoline. Mercedes-Benz recommends
only the use of quality gasoline containing
additives that prevent the build-up of
carbon deposits.
After an extended period of using fuels
without such additives, carbon deposits
can build up especially on the intake valves
and in the combustion area, leading to
engine performance problems such as:

Warm-up hesitation

Unstable idle

Knocking/pinging

Misfire

Power loss
Warning!G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact, extin-
guish all smoking materials. Never allow
sparks, flame or smoking materials near
gasoline!
!
To maintain the engine’s durability and
performance, premium unleaded gaso-
line must be used. If premium unleaded
is not available and low octane fuel is
used, follow these precautions:

Have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible.

Avoid full throttle driving and abrupt
acceleration.

Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded
with a light load such as two
persons and no luggage.

Do not exceed2/3 of maximum
accelerator pedal position if the
vehicle is fully loaded or operating
in mountainous terrain.

Windshield washer and headlamp
cleaning system*
Both the windshield washer and headlamp
cleaning system* are supplied from the
windshield washer fluid reservoir.
The washer fluid reservoir has a capacity of
approx.:

3.2 US qt (3.0 l) in vehicles without
headlamp cleaning system*

6.4 US qt (6.0 l) in vehicles with
headlamp cleaning system*
Refill the reservoir with MB Windshield
Washer Concentrate “MB SummerFit”
and water (or concentrate and com-
mercially available premixed wind-
shield washer solvent/antifreeze,
depending on ambient temperatures).Windshield and headlamp washer fluid

For temperatures above freezing point, use
MB Windshield Washer Concentrate
“MB SummerFit” and water:

1 part “MB SummerFit” to 100 parts
water
(1.34floz [40ml]“MBSummerFit” to
1 gallon [4.0 l] water)
For temperatures below freezing point, use

ble. Do not spill washer solvent/antifreeze
on hot engine parts, because it may ignite
and burn. You could be seriously burned.
