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
RDISTRONIC PLUS
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 influ-
enced 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.
