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†), i.e close to the
red zone of the temperature gauge.
!
Excessive coolant temperature triggers a
warning in the multifunction display.
The engine should not be operated with a
coolant temperature above 248‡ (120†),
i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
Tachometer
The red marking on the tachometer
(
Y
page 29) denotes excessive engine speed.
!
Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
To help protect the engine, the fuel supply is
interrupted if the engine is operated within
the red marking.
Outside temperature indicator
The outside temperature indicator is on the
bottom left-hand side of the instrument
cluster (
Y
page 29).
G
Warning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
Fuel gauge
The fuel gauge is on the left-hand side of the
instrument cluster (
Y
page 29). Once the fuel
level has fallen below the reserve mark, the
yellow segment indicator for the fuel reserve
comes on.
