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

bustion engine is switched off. All of theve hi‐
cle functions 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 do not depress the accelera tor or brake
pedal (e xcept for light brake applications).
% Glide mode can also be activated if you ha ve
selected the "Eco" setting forth e drive in the

nction of the 4MATIC
4MATIC ensures that all four wheels are driven
when needed. Toge ther 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
use winter tyres (M+S tyres), with sn ow
