stop-and-go city traffic, the coolant tem-
perature may rise close to 248° F (120°C),
i.e. close to the red zone of the tempera-
ture gauge.
The engine should not be operated with
the coolant temperature above 248° F
(120°C), i.e. in the red zone of the temper-
ature gauge. 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 over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.
Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
from the engine if you see or hear steam
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
iExcessive coolant temperatures trigger
a warning in the multifunction display.

Tachometer
The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
S 55 AMG
The tachometer of the S 55 AMG does not
have a red marking denoting excessive en-
gine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive engine speed.
Outside temperature indicator
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. There-
fore, the accuracy of the displayed temper-
a t u r e c a n o n l y b e v e r i f i e d b y c o m p a r i s o n t o
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.
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

Indicated temperatures just above the freez-

face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

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, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit 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 (approximate-
ly 13.5 m) every second.

General notes
Should excessively high temperatures oc-
cur while in CD mode,
CD TEMP HIGH
will
appear on the display and muting will take
place. The unit will then switch back to the
last operating mode used until the temper-
ature has decreased to a safe operating
level.
Should excessively low temperatures oc-
cur while in CD mode,
CD TEMP LOW
will ap-
pear on the display, but the CD will
continue to play.
Handle CDs carefully to prevent interfer-
ence during playback. Avoid fingerprints
and dust on CDs. Do not write on CDs or
apply any label or other material to them.Use only original CDs. Using copied CDs
may create problems during playback.
Clean CDs from time to time with a com-
mercially available cleaning cloth. No sol-
vents, anti-static sprays, etc. should be
used for cleaning. Replace the CD in its
case after use. Protect CDs from heat and
direct sunlight.
Only use CDs, which bear the label shown
and that conform to the compact disc dig-
ital audio standard (IEC 60908).Use of CDs which do not meet this stan-
dard may cause damage to the CD chang-
er. Do not play single-CDs (80 mm) with an
adapter.
For information operating the CD changer
refer to the separate COMAND operating
instructions.
