Urban driving
In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (
Ypage 23).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Renergy recuperation
Relectric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/ h).
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
When driving on a highway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfortdrive program
and a speed of 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.
Further information on the automatic engine
switch-off (
Ypage 23).
Refueling
Refueling
General information
Observe the important safety notes under
"Refueling" in the vehicle Operator's Manual. Pressure in the fuel tank must be released
before refueling. Otherwise, the fuel filler flap
cannot be opened.
If you unlock/lock the vehicle from the outside,
the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed in
the instrument cluster
8. The arrow next to
the filling pump indicates the side of the vehicle.
Preparing to refuel
XSwitch off the engine.
XRemove the SmartKey from the ignition lock.
or, on vehicles with KEYLESS‑ GO:
XOpen the driver's door.

If, after the charging process, the charging cable
is:
Rleft connected to the power socket, the cur-
rently selected values will be used for the nextcharging process.
Rremoved from the power socket, the values
will be reset to the minimum setting for the
next charging process. You may then need to reset the values of the maximum charge cur-
rent.
iIf the vehicle requires more time than usual
when charging, check the maximum charge
current settings using the controls on the
charging cable or in the on-board computer's
menu.

tion is either the anticipated condition of charge
at the programed departure time or the time
when the high-voltage battery will be fully
charged (

iDepending on the temperature, the fan and
battery cooling system may audibly switch on
during the charging process.

General notes
It is recommended that you charge your vehicle
using a wallbox or at a charging station.
Make sure that the maximum charging current is
not limited in the Settings

board computer. You must select the maximum
value if charging at a wallbox or a charging sta-
tion (
