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 (
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 tangible double pulse in the haptic acceler-
ator pedal gives you a recommendation to
release the accelerator pedal. By this means,
in HYBRID, E-MODE or E-SAVE operating
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+ ( page 285).
Y
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 safe distance
from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt brak-
ing.
During partial electric driving, pulling away
and acceleration, the electric motor supports
the internal combustion engine.
During overrun in transmission position D and
braking, the electric motor will operate as a
generator.

function ( page 288).

PLUG-IN HYBRID operation
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 electromechanically assisted steer-
ing 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 performed:
entirely by electric propulsion
R
in combination with the internal combus-
R
tion engine
When accelerating at an increased or full
load, boost mode is utilized. The electric
motor supports the internal combustion
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:
energy recovery takes place even when the
R
vehicle is decelerating purely in overrun
mode ( page 276). The electric motor
Y
operates as a generator and stores the
recovered energy in the high-voltage bat-
tery.
when the brakes are applied lightly, the
R
vehicle is slowed down further by the elec-
tric motor. This increases the energy recov-
ery taking place (
Y
motor operates as a generator and stores
the recovered energy in the high-voltage
battery.
when the brakes are applied with greater
R
force, the service brakes are also used to
slow the vehicle down. The two systems
work together.
Urban driving
Energy is recuperated during frequent decel-
eration and stopping in city traffic.
