Driving tips
General driving tips
Drive carefully and maintain a safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric driving, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor will operate as a gen- erator.
Further information on the ECO start/stop func-
tion (
Ypage 23).
You can find further driving tips in the vehicle
Operator's Manual.
Stationary vehicle
If the vehicle is stopped, the combustion engine
is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tromechanically assisted steering gear allows
you to use the power steering without reduced
comfort.
Acceleration
Depending on the operating mode, pulling away
and driving under low load conditions are per-
formed:
Rentirely by electric propulsion
Rin combination with the internal combustion
engine
When accelerating rapidly under increased or
full load, increased boost mode is utilized. The
electric motor supports the combustion engine
by providing additional drive torque.
Overrun mode or braking
There are three possible operating modes when
the hybrid vehicle is decelerating:
Renergy recovery takes place even when the
vehicle is decelerating purely in overrun mode
(
Ypage 20). The electric motor operates as a
generator and stores the recovered energy in
the high-voltage battery
Rwhen the brakes are applied lightly, the vehi-
cle is slowed down further by the electric
motor. This increases the energy recovery
taking place (
Ypage 20). The electric motor
operates as a generator and stores the recov-
ered energy in the high-voltage battery
Rduring heavy braking, the service brake is also
used to slow down the vehicle. The two sys-
tems work together
26Driving tips
Driving and parking

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.
The vehicle electronics now have status 0.
This is the same as the SmartKey having been
removed.

XOnly fill the tank until the pump nozzle
switches off.
Do not add any more fuel after the pump stops filling for the first time. Otherwise, fuel may
leak out.
Closing the fuel filler flap
XReplace the cap on the filler neck and turn
clockwise until it engages audibly.
XClose the fuel filler flap.

cle.
If you drive at speeds above 1 mph (2 km/h)
with the fuel filler flap open, the Fuel Filler
Flap Openmessage is shown in the multifunc-
tion display.
If you are driving with the fuel filler cap open, the

sage appears on the multifunction display.
In addition, the ;Check Engine warning
lamp may light up.

process is resumed automatically.
For information on problems relating to the
charging process, see (
Ypage 35).
Setting the maximum charge current
GWARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check
the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
!An excessive charge current can blow a fuse
or lead to overheating of the external power
supply. Check whether the external power
supply is compatible with the set charge cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
Before starting the charging process at a power
socket, check the maximum permissible charge
current for the relevant power socket or the
building.
You can set the maximum permissible charge
current:
Ron the controls of the charging cable
Rin the Settingsmenu of the on-board com-
puter (Ypage 43)
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current
in the on-board computer menu if:
Rit is not possible to set the charge current on
the charging cable
Rthe precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
How to set the maximum permissible charge
current on the charging cable, is described as
follows.
XTo adjust the setting: press button?
repeatedly until the desired setting is selec-
ted in display =.
RTwo LEDs are flashing: minimum setting
RAll LEDs are flashing: maximum setting

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.
