If th e engine was switched off automatically
and youth en get out, it star ted again auto‐

Before leaving theve hicle,alw ays switch
off the ignition and secure theve hicle
against rolling away. Displ

R 00D5: Not all on vehicle conditions for an
automatic engine stop are met.
% Depending on the engine, the00D6 symbol
fi rs t appears du ring the automatic engine
st op or during the journe y.
If all theve hicle conditions for an automatic
engine stop are met, the engine will be automati‐
cally switched off:
R Vehicles with manual transmission: you
decelerate theve hicle toa lo wer speed, then
engage neutral 005Cand then release the
clutch pedal.
R Vehicles with automatic transmission: you
st op theve hicle in transmission position 005B
or 005C.
The engine restarts automatically in thefo llowing
cases:
R Vehicles with manual transmission: Yo u
depress the clutch pedal.
R Vehicles with automatic transmission: Yo u
re lease the brake pedal in transmission posi‐
tion 005Band with the HOLD function deactiva‐

R Vehicles with automatic transmission: Yo u
select transmission position 005Bor005E. R
You depress the accelera tor pedal.
R Ave hicle automatic engine start is required.
If th e engine was switched off bythe ECO start/

% In wintry
road conditions, the maximum

If yo ufa ilto adapt your driving style, 4MATIC can
neither reduce therisk of an accident nor over‐

4MATIC is only an aid. You are responsible espe‐

good time and forst ay ing in lane. AIRMATIC
Fu

especially critical situations, Active Brake Assi st
can initiate auto nomous braking dire ctly.In this
case, thewa rning lamp and warning tone occur
simul taneously wi th the braking application.
If yo u apply the brake yourself in a situation

If all requ irements are met, theÇ display
appears in the multifunction displa y.The sy stem

Ac tive Parking Assist can assist you with an
active steering inter vention and brake application
du ring pa rking and exiting the parking space. The
active brake application is dependent on the
countr y-specific version of theve hicle. On vehi‐

R Active Parking Assist may steer too early.
R The vehicle may not stop in front of these
