2005 MERCEDES-BENZ C COUPE Owner's Manual

120 Controls in detailInstrument clusterCoolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
(page 25).During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G


Driving when your engine is badly
overheated can cause some fluids which
may have leaked into the engine
compartment to catch fire. You could be
seriously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

121 Controls in detail
Instrument cluster
Trip odometer
Make sure you are viewing the trip
odometer and main odometer in the
multifunction display (
page 123).

If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel until the trip odometer appears
(page 124).

Press and hold the reset button in the
instrument cluster (
page 119) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(page 24) denotes excessive engine
speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
!Avoid driving at excessive engine
speeds, as it may result in serious
engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

122 Controls in detailInstrument clusterThe outside temperature is indicated in the
multifunction display (
page 123). For
information on how to select the unit of the
indicated temperature, i.e. degrees
Celsius (°C) or degrees Fahrenheit (°F),
see “Selecting temperature display mode”
(
page 137).
The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. This
means that the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs, etc.).When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.

G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions
permit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.

124 Controls in detailControl systemMultifunction steering wheel
The displays in the multifunction display
and the settings in the control system are
controlled by the buttons on the multifunc-
tion steering wheel.Pressing any of the buttons on the multi-
function steering wheel will alter what is
shown in the multifunction display.
The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or sub-
menus.
The individual functions are then found
within the relevant menu (radio or CD
operations under
AUDIO
, for example).
These functions serve to call up relevant
information or to customize the settings
for your vehicle.
