To protect against engine overrev, the automatic
transmission will shi up to the next gear when
maximum engine speed has been reached.
Glide mode function
With an anticipatory driving style, glide mode
helps you to reduce fuel consumption.
Glide mode is characterised by the following:
R
The combustion engine is disconnected from
the drivetrain and continues to run in neutral.
R
The transmission position display h is shown
in green.
R
Vehicles with 48 V on-board electrical system:
the combustion engine is switched o
depending on the driving situation. All of the
vehicle functions remain active.
Glide mode is activated if the following conditions
are met:
R
Drive program ; is selected.
R
The speed is within a suitable range.
R
The road's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
R
There is no trailer coupled up to the trailer
hitch, and no bicycle rack tted.
R
The state of charge of the battery is sucient.
R
You do not depress the accelerator or brake
pedal (except for light brake applications).
%
Glide mode can also be activated if you have
selected the "Eco" setting for the drive in the
drive program =.
Glide mode is deactivated again if one of the con-
ditions is no longer met.
Vehicles with Active Distance Assist DISTRONIC:
when Active Distance Assist DISTRONIC is active,
the glide mode function is not available.
Glide mode can also be prevented by the following
parameters:
R
Incline
R
Downhill gradient
R
Temperature
R
Altitude
R
Speed
R
Operating condition of the engine
R
Trac situation

You can end glide mode by operating a steer-
ing wheel gearshi paddle (/ page 271).
Function of 4MATIC
4MATIC ensures that all four wheels are driven.
Together with ESP
®
and 4ETS, 4MATIC improves
the traction of your vehicle whenever a driven
wheel spins due to insucient traction.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor override
the laws of physics. 4MATIC cannot take account
of road, weather and trac conditions. 4MATIC is
only an aid. You are responsible in particular for
maintaining a safe distance from the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane.
%
In wintry road conditions, the maximum eect
of 4MATIC can be achieved only if you use
winter tyres (M+S tyres), with snow chains if
necessary.
