Controls in detail
Instrument cluster
The coolant temperature gauge is located
on the right-hand side of the instrument
cluster.
The temperature displayed may climb to
120 °Cwhen the vehicle is being driven in
normal conditions and if the coolant con-
tains the correct concentration of corro-
sion inhibitor and antifreeze.
The red band in the rev counter indicates
the engine's overrevving range. The engine
speed is limited to protect the engine when
the red band is reached.
! Do not driv ein the overrevving range. Doing
so could damage the engine. There may be a short delay before a lower
outside temperature is displayed, for
example after leaving a garage.
There may also be a short delay before a
rise in the outside temperature is dis-
played. This prevents an incorrect temper-
ature displ
aycaused by heat from the
engine when the vehicle is stationary or
mo ving slowly.
i You can set the unit for the out side temper-
ature display using the operating syst em
( =
page 119). Co

Risk of accident Even if the temperature displayed is just
above freezing point, the road
surface may
still be icy, especially inwooded areas or on
br idges. The vehicle could skid if you fail to
adapt your driving style accordingly. For this
reason, always adapt your driving style and
speed to the weather conditions. 209en_d2.boo Seite
