Notes on economical driving
In order to save energy, with smart electric
drive a part of the kinetic energy is recuper-
ated and stored in the high-voltage battery.
When the driver releases the accelerator
pedal, the vehicle decelerates.
In the following cases, the vehicle does not
decelerate, or only decelerates to a limited
extent, when the accelerator pedal is
released:
R
the gear lever is in position h and the
vehicle is rolling backwards
R
the gear lever is in position k and the
vehicle is rolling forwards
On steep slopes, the vehicle may not be held
at all or only be held to a limited degree.
In the following cases recuperation is
restricted:
R
the high-voltage battery is fully charged
or too cold
R
the power electronics or motor has over-
heated
Recommendations for driving economically:
R
accelerate moderately
R
observe the power availability display
(Y page 64)
R
drive with care
R
use the air conditioning and the electrical
consumers sparingly
R
have maintenance work carried out at the
specified service intervals
You can use ECO mode in order to save more
energy.
ECO mode has the following characteristics:
R
reduced torque and significantly reduced
power. This supports a particularly effi-
cient, steady driving style. The speed is
reduced to approx. 110 km/h.
R
the performance of the air-conditioning
and heating systems is reduced
R
the maximum available recuperation is
activated
R
reduced acceleration
R
the "radar-based recuperation" function
is switched off
To increase acceleration when in ECO mode,
depress the accelerator pedal beyond the
pressure point.

If the energy-saving function is activated,
the ECO display is shown in the on-board
computer.
The energy-saving function is switched
off when the ignition is restarted.
