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.
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.

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.
