General notes The Head-up Display projects information from
the navigation system and the driver assistance
systems above the dashboard into the driver's
field of vision. This way, the Head-up Display
enables drivers to see information without hav-
ing to take their eyes off the road.
A requirement for the display of the content is
that the following functions are available in the
vehicle and are switched on:
R Cruise control
R SPEEDTRONIC
R DISTRONIC PLUS
R Traffic Sign Assist
R Navigation
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:
R the driver's seat position
R the positioning of the display image
R the general light conditions
R sunglasses with polarisation filters
R wet road surfaces
R blocking 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.
i Vehicles with the head-up display are equip-
ped with a special windscreen. Should repairs
be necessary, have the windscreen replaced
at a qualified specialist workshop.

Vehicle preparation is not necessary on vehi- cles with MOExtended tyres.
R a TIREFIT kit (Y page 340)
R an emergency spare wheel (certain countries
only) (Y page 369)
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop.
Vehicles with a Mercedes-Benz emergency call
system that are not equipped with a TIREFIT kit:
in the event of a flat tyre, contact the Customer Assistance Centre for the Mercedes-Benz emer-
gency call system (Y page 321).
