Coolant temperature gauge
The coolant temperature gauge is located 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 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 30) 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
displayed in the multifunction display
(
Y
page 133).
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 30). Once the fuel
level has fallen below the reserve mark, the
yellow fuel tank reserve warning lamp
4
for the fuel reserve comes on.
