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 237).
Changes in the outside temperature are dis-
played after a short delay.
Coolant temperature display
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.
!A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The engine
will otherwise be damaged.
All vehicles except PLUG-IN HYBRID vehicles:
the coolant temperature display is in the lower
section of the tachometer (
Ypage 36). PLUG-IN HYBRID vehicles: the multifunction dis-
play shows the coolant temperature in the
Coolant
submenu (Ypage 246).
Under normal operating conditions and with the
specified coolant level, the coolant temperature may rise to 248 ‡ (120 †).

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.
A requirement for the display of the contents is
that the following functions are available in the
vehicle and are switched on:
RCruise control
RDISTRONIC PLUS
RTraffic Sign Assist
RNavigation
The head-up display allows the driver to see all
of the information without having to take his
eyes off the road.
Important safety notes
The head-up display is only an aid and is not a
substitute for attentive driving.
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.
