Electric motor power display The electric motor power display is on the
right-hand side of the instrument cluster.
R Area :to; (E-DRIVE):
This shows the electric output from the
electric motor, e.g. during electric opera-
tion or in boost mode.
When the motor is switched on, the display
is at limit :. With increasing pressure on the accelerator pedal the display fills up
from
:to;.
Driving with the electric motor: when the
display reaches limit ;, the combustion
engine is switched on. If the display is
approaching limit ;and you remove your
foot from the accelerator pedal, the display
empties again. The combustion engine is
not switched on. At low speeds, you can
thereby control the electric operation
usage so that you only drive in electric
mode.
Driving with the combustion engine: the
electric motor supports the combustion
engine by providing additional torque
(boost mode) until the display reaches
limit ;.
You can also select the operating mode of
the hybrid drive system (Y page 290).

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 currently provide.
Noiseless start operation is dependent on the
outside temperature and the operating tem-
perature of the internal combustion engine. If
not all conditions for noiseless start operation are fulfilled, the vehicle starts with the inter-
nal combustion engine. X

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
