Sy stem limitations
ECO Assist can function more precisely if the
ro ute is main tained when route guidance is
active. The basic function is also available with‐
out active route guidance. Notall information
and traf fic situations can be fore seen. The qual‐
ity depends on the map data.
ECO Assist is only an aid. The driver is responsi‐
ble forke eping a safe dis tance from theve hicle
in front, forve hicle speed and for braking in
good time. The driver must be ready tobrake at
all times ir respective of whe ther the sy stem
inter venes.
The sy stem may be impaired or may not function
in thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, high lyvariable
shade conditions, rain, sno w,fog or heavy
spr ay.
R Ifth ere is glare, e.g. from oncoming traf fic,
di re ct sunlight or reflections. R
Ifth ere is dirt on the windscreen in the vicin‐
ity of the multifunction camera or the camera
is mis ted up, damaged or obscured.
R Ifth e traf fic signs are ha rdtodetect, e.g. due
to dirt or snow or insuf ficient lighting, or
because they are obscured.
R Ifth e information on the navigation sy stem's
digital map is incor rect or out of da te.

Wi th an anticipatory driving style, Glide mode
helps youto reduce fuel consum ption.
Glide mode is characterised bythefo llowing:
R the combustion engine is disconnected from
th e driv etra in and the engine continues to
ru n in neutral.
R the transmission position his displa yed in
green in the multifunction displa y.
R vehicles with a 48 V on-board electrical
sy stem (EQ Boost technology): the com‐
bustion engine is switched off depending on
th e driving situation. All of theve hicle func‐
tions remain active.
Glide mode is activated if thefo llowing condi‐
tions are me t:
R drive prog ram ; is selected.
R the speed is within a suitable range. R
thero ad's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
R there is no trailer coupled tothe trailer hitch,
and no bicycle rack fitted.
R you are no lon ger depressing the accelera tor
or brake pedal.
% Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive in the

Glide mode is deactivated again if one of the
conditions is no longer met.
Glide mode can also be pr evented bythefo llow‐

Fu
nction of the 4MATIC
4MATIC ensures that all four wheels are driven
when needed. Toget her with ESP ®
and 4ETS,
4MATIC impr ovesth e traction of your vehicle
whene ver a driven wheel spins due toinsuf fi‐
cient traction.
If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor over‐
ri de the la wsof ph ysics. 4MATIC cannot take
account of road, weather and traf fic conditions.
4MATIC is only an aid. You are responsible espe‐
cially for maintaining a safe dis tance from the
ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in lane.
% In wint ryroad conditions, the maximum
ef fect of 4MATIC can be achie ved only if you
