fect or malfunction has been subject to
repair two or more times, and you have

four or more times and you have direct-
ly notified us in writing of the need for

of repair of the same or different sub-
stantial defects or malfunctions for a

Instrument cluster
Coolant temperature indicator
The coolant temperature indicator is on
the right side in the instrument cluster
(page 24).
During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 120°C.
The engine should not be operated with
the coolant temperature above 120°C.
Doing so may cause serious engine
damage which is not covered by the
Mercedes-Benz Limited Warranty.
Trip odometer
Make sure you are viewing the stan-
dard display in the multifunction dis-
play (
page 144).
If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel repeatedly until the standard dis-
play appears (
page 140).
Press and hold the reset button on the
instrument cluster (
page 136) until
the trip odometer is reset.
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 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.
iExcessive coolant temperature triggers
a warning in the multifunction display
(page 398) and the red coolant warn-
ing lamp in the instrument cluster
comes on (
page 377).
