ognise dangers.
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 005Bis 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.
0009 Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive in the
drive prog ram =.
Glide mode is deactivated again if one of the
conditions is no longer met. Glide mode can also be pr
evented bythefo llow‐
ing parame ters:
R incline
R downhill gradient
R temp erature
R height
R speed
R operating status of the engine
R traffic situation
0009 Glide mode can be ended bypressing the

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. 0009
In wint ryroad conditions, the maximum
ef fect of 4MATIC can be achie ved only if you
use winter tyres (M+S tyres), with sn ow
