20Driving
Dr iving an d parking
If manual gearshifting is deactivated, the auto-
matic transmission shifts:
Rinto the drive program that was last selected,
and
Rinto the driving mode that was last selected
If you change the drive program, the operating
mode that was last selected is stored for approx-
imately 60 seconds. After this time, the HYBRID
operating mode is automatically activated.
Starting the engine
The vehicle starts in electric mode without the
internal combustion engine (noiseless start).
The internal combustion engine starts only after the power demanded by the driver exceeds the
available power that the electric motor can cur-
rently provide.
Noiseless start operation is dependent on the
outside temperature and the operating temper- ature of the internal combustion engine. If not all
conditions for noiseless start operation are ful-
filled, the vehicle starts with the internal com-
bustion engine.
Observe the notes on starting in the vehicle
Operator's Manual.
XSwitch on the ignition.
XDepress the brake pedal.
XStart the vehicle (see the vehicle Operator's
Manual).
When the vehicle is operational, the READY
indicator lights up in the multifunction display
(
Ypage 39).
Pulling away
XDepress the brake pedal and keep it
depressed.
XShift the transmission to position Dor R.
XIf the Apply Brake to Shift from 'P'display message appears in the multifunction display, depress the brake pedal more firmly
and select the desired transmission position.
XRelease the brake pedal.
XCarefully depress the accelerator pedal.
You can find further information on pulling away
in the vehicle Operator's Manual.

General notes
The ECO start/stop function switches the com-

multifunction display is
off.For example, self-diagnosis is not yet complete or the hybrid drive
system is malfunctioning.
XSwitch off the ignition and turn it back on.

If the internal combustion engine still does not start:
XConsult a qualified specialist workshop.

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

Driving and parking
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.

lights up, this means the following:

If the charging cable is connected to the vehicle, you cannot start the engine or move the vehicle.
As soon as the charging process begins, you can
display the charging prediction on the Settings
on-board computer menu. The charging predic-
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 (
