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.Glide mode is activated if
thefo llowing condi‐

R drive program ;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
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‐

4MATIC is only an aid. You are responsible espe‐ cially
for maintaining a safe dis tance from the

fety sy stems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. Keep these
parts free of dirt, ice and slush (/ page 386).
The sensors must not be co vered, forex ample
