2004 MERCEDES-BENZ C CLASS COUPE ESP

334 Technical dataFuels, coolants, lubricants, etc.Gasoline additives
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build-up of carbon depos-
its.
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 en-
gine performance problems such as:

Warm-up hesitation


Unstable idle


Knocking/pinging


Misfire


Power loss
Do not blend any specific fuel additives
with fuel. This only results in unnecessary
cost and may be harmful to engine opera-
tion. Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.
Flexible Fuel Vehicles
Flexible Fuel Vehicles are identified by a la-
bel reading Premium gasoline or E85
only!
on fuel filler flap).
These vehicles are designed to operate on
premium unleaded gasoline or Ethanol fuel
(E85), or on any mixture of these two.
Ethanol fuel (E85) is a mixture of approxi-
mately 85% Ethanol and 15% unleaded gas-
oline. Switching fuels
For best performance and driveability it is
recommended to use either one or the oth-
er fuel. A refueling pattern that alternates
between the two different fuels should be
avoided if possible.
Warning!
G
Ethanol fuel (E85) and its fumes are highly
flammable, poisonous and burn easily. Etha-
nol fuel can cause serious injuries if ignited
or if you come into contact with it or inhale
fumes of it. Avoid inhalation of Ethanol
fumes and skin contact with Ethanol. Extin-
guish all open flames before fueling. Never
smoke or create sparks close to Ethanol.

340 Technical dataConsumer informationTemperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. Grade C corresponds to a level
of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law.
Warning!
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.

342 Technical termsCollapsible tireAn especially compact spare tire that
must be inflated with a provided air
pump before using. It should only be
used to bring the vehicle to the nearest
service station.
COMAND* (C
ockpit M
anagement and D
ata Sys-
tem)
Information and operating center for
vehicle sound and communications
systems, including the radio and navi-
gation system, as well as other optional
equipment (CD changer, telephone,
etc.).
Control system The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to ad-
just settings. Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.
Engine number The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.
Engine oil viscosity Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP (E

Improves vehicle handling and direc-
tional stability. ETD
(E

Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem's threshold to tighten the seat
belts.
->SRS
FSS (F

Service indicator in the multifunction
display that informs the driver when
the next vehicle maintenance service is
due.
Gear range Number of gears which are available to
the automatic transmission for shifting.
The automatic gear shifting process
can be adapted to specific operating
conditions using the gear selector le-
ver.

Technical terms
SRS
(S
upplemental R
estraint S

Seat belts, emergency tensioning de-
vice and airbags. Though independent
systems, they are closely interfaced to
provide effective occupant protection.
Tele Aid* System (T

dentification on D
e-
mand)
The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available. Tightening torque
Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.
Tire speed rating Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction Force exerted by the vehicle on the
road via the tires. VIN
(V

dentification N
umber)
The number set by the manufacturer
and placed on the body to uniquely
identify each vehicle produced.
Voice control system* Voice control system for car phones,
portable cell phones and audio sys-
tems (radio, CD, etc.).
