Coolant temperature gauge
The coolant temperature gauge is on the
left side in the instrument cluster
( page 30).
Warning!
Driving when your engine is 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.
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.
!
Excessive coolant temperature triggers a
warning in the multifunction display
( page 657).
The engine should not be operated with the cool-
ant temperature above 248°F (120°C), i.e. in
the red zone of the coolant temperature gauge.
G
Doing so may cause serious engine damage
which is not covered by the Mercedes-Benz Lim-
ited Warranty.
i
During severe operating conditions,
e.g. stop-and-go traffic, the coolant temperature
may rise close to 248°F (120°C), i.e. close to
the red zone of the temperature gauge.
