114 Controls in detailInstrument clusterCoolant temperature gaugeDuring 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 en-
gine 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 an can occur just by
opening the 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 the
engine has cooled down.
!Excessive coolant temperature triggers
the coolant temperature warning lamp
(page 300) and a warning in the
multifunction display (
page 320).

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.

General notes
Should excessively high temperatures oc-
cur while in CD mode,
CD TEMP HIGH
will
appear on the display and the CD will be
muted. The unit will then switch back to
the last operating mode used until the tem-
perature 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 labels or other material to them.Only use original CDs. Using copied CDs
may create problems during playback.
Clean CDs from time to time with a com-
mercially available cleaning cloth. Do not
use solvents, anti-static sprays, etc. for
cleaning. Replace the CD in its case after
use. Protect CDs from heat and direct sun-
light.
Only use CDs, which bear the label shown
and that conform to the compact disc
digital audio standard (IEC 60908). You
can therefore only use CDs with a maxi-
mum thickness of 1.3 mm.
iUse of CDs which do not meet this
standard may cause damage to the CD
changer. Do not play single-CDs
(80 mm) with an adapter.
Your CD drive has been designed to
play CDs which correspond to the
EN 60908 standard.
If you insert thicker data carriers, e.g.
ones that have data on both sides (one
side with DVD data, the other side with
audio data), they cannot be ejected and
will damage the drive.Warning!

does not contain any parts which can be ser-
viced by the user. For safety reasons, have
any service work which may be necessary
performed only by qualified personnel.
