Activating when driving with the combustion
engine:
X Pull the left or right steering wheel gearshift
paddle (Y page 201).

Haptic accelerator pedal General notes
The haptic accelerator pedal helps you to
reduce the fuel consumption and emissions
of your vehicle.
There are two different functions available for
this purpose:
R an additional point of resistance in E-MODE
operating mode (Y page 290)
R a double pulse in drive program E
(Y page 295)
Additional point of resistance in the hap-
tic accelerator pedal
The maximum available electric performance
is indicated by a tangible point of resistance
in the haptic accelerator pedal.
The additional point of resistance is available in E-MODE operating mode (Y page 290).
If you depress the haptic accelerator pedal
beyond the pressure point, the combustion
engine is switched on.
Double pulses in the haptic accelerator
pedal
A noticeable double pulse in the haptic accel-
erator pedal is a recommendation that you
should release the accelerator pedal. By this
means, in HYBRID,E-MODE orE-SAVE oper-
ating mode the combustion engine can be switched off and disconnected from the
power train (overrun mode).
The double pulse is available in drive program
E (Y page 295).
After the accelerator pedal has been
released, the coasting characteristics of the
vehicle are adapted to the traffic conditions
To avoid getting too close to the vehicle in
front, you must apply the brakes manually
when necessary.
Driving tips General driving tips
Drive carefully and maintain a suitable dis-
tance from the vehicle in front. Avoid frequent
and sudden acceleration as well as abrupt
braking.
During partial electric drive, pulling away and acceleration, the electric motor supports the internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an
alternator.
Further information on the ECO start/stop
function (Y page 298).
Additional driving tips (Y page 222).
Stationary vehicle
If the vehicle is stopped, the combustion
engine is, for the most part, switched off.
Automatic climate control continues to func-
tion. The electro-mechanically assisted steer-
ing gear allows use of the power steering
without loss of comfort.
Acceleration
Depending on the operating mode, pulling
away and driving under low load conditions
are performed:
R entirely by electric propulsion
R in combination with the internal combus-
tion engine
When accelerating at an increased or full
load, boost mode is utilised. The electric
motor supports the internal combustion PLUG‑IN HYBRID operation
297Driving and parking Z

engine by providing additional torque when
the accelerator is depressed rapidly.
Overrun mode or braking
There are three possible operating modes
when the hybrid vehicle is decelerating:
R When coasting and decelerating, energy
recuperation is already taking place
(Y page 287). The electric motor functions
as an alternator and stores the recuperated energy in the high-voltage battery.
R When braking gently, the electric motor
increases the deceleration of the vehicle.
Energy recuperation is increased
(Y page 287). The electric motor functions
as an alternator and stores the recuperated energy in the high-voltage battery.
R During heavy braking, the service brake is
also used to slow down the vehicle. Both
systems work together.
Driving in the city
Energy is recuperated during frequent decel-
eration and stopping in city traffic.
The vehicle can be driven by the electric
motor alone up to a speed of approximately
140 km/h.
The vehicle is driven by the electric motor
alone only when all conditions for the auto-
matic engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 298).
Driving on inter-urban roads
The following phases are possible when driv-
ing on inter-urban roads:
R rapid acceleration (boost mode)
R constant energy consumption
R energy recuperation
R electric operation mode
Depending on the characteristics of the
route, there may be a lot of recuperated
energy available. This reduces consumption
and emissions. Driving on the motorway
When driving on a motorway, the decrease in
wasted power has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his foot from the accel-
erator pedal in drive program Eand a speed of
160 km/h is not exceeded, the combustion
engine is automatically switched off.
Further information on the automatic engine
switch-off (Y page 298).
ECO start/stop function General notes
The ECO start/stop function switches the
internal combustion engine off automatically
when the vehicle stops moving and at high
speeds (Y page 299).
All vehicle systems remain active, e.g. the
automatic climate control.
The ECO start/stop function is only available in drive programs Cand E. Electric-only oper-
ation is only possible in drive programs Cand
E. Additional information for drive programs
(Y page 295).
Automatic engine switch-off
The internal combustion engine is switched
off automatically if:
R the driver removes his foot from the accel-
erator in drive program Eand a speed of
160 km/h is not exceeded (Y page 299)
R the internal combustion engine has
reached its operating temperature
R the driver's seat belt is fastened and the
driver's door is closed
R the driver only slightly depresses the accel-
erator pedal in order to, for example, main- tain the current speed for a limited distance
R the bonnet is closed and engaged properly
R the high-voltage battery is charged suffi-
ciently
R no malfunctions are present in the hybrid
drive system 298
