Controls in detail
Instrument cluster
Steam from an overheated engine can
cause serious burns which can occur just
by opening the engine hood. Stay away
from the engine if you see or hear steam
coming from it.
Stop the vehicle in a safe location away
from other traffic. Turn off the engine, get
out of the vehicle and do not stand near the
vehicle until the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†).
! Excessive coolant temperature triggers a
warning in the multifunction display and the
red coolant temperature warning lamp
in the instrument cluster comes on.
D
The engine should not be operated with a
coolant temperature above 248‡ (120†).
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz
Limited Warranty.
