Tachometer
!
Do not drive in the overrevving range, as this
could damage the engine.
The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the temperature measured and
does not record the road temperature.
The outside temperature display is in the multi-
function display (
Ypage 194).
Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature gauge
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!If the coolant temperature is too high, a dis-
play message is shown.
If the coolant temperature display is in the
area marked in red, do not continue driving.
Otherwise, the engine will be damaged.
The coolant temperature gauge is in the lower
section of the tachometer (
Ypage 36).
Under normal operating conditions and at the
correct coolant level, the display may rise to the
red mark.

Head-up display
General notes
The head-up display projects information from
the navigation system and the driver assistance
system above the dashboard into the driver's
field of vision. The head-up display allows the
driver to see all of the information without hav-
ing to take their eyes off the road.
A requirement for the display of the contents is
that the following functions are available in the
vehicle and are switched on:
RCruise control
RDistance Pilot DISTRONIC
RTraffic Sign Assist
RNavigation
Important safety notes
The head-up display is only an aid and is not a
substitute for attentive driving.
Speed limits and overtaking restrictions are not
always correctly displayed. Traffic signs always
have priority over the Traffic Sign Assist display.
The visibility of the head-up display is influenced by the following conditions:
Rthe driver's seat position
Rthe positioning of the display image
Rthe general ambient light
Rsunglasses with polarization filters
Rwet roads
Rblocking of sunlight by objects on the display
cover
In the event of extreme sunlight, sections of the
display may fade. This can be reversed by
switching the head-up display off and on again.
iVehicles with the head-up display are equip-
ped with a special windshield. Should repairs
be necessary, have the windshield replaced at
a qualified specialist workshop.
