Mercedes-Benz E 400 HYBRID 2014, Supplemental Operating Instructions

Page: 28 / 52

R
During partial electric driving, pulling away
and acceleration, the electric motor
supports the internal combustion engine.
R
During overrun in transmission position D
and braking, the electric motor will operate
as a generator.

start/stop function (

tips, see the vehicle Operator's Manual.
Stationary vehicle
In this operating mode, the internal
combustion engine is primarily switched off.
Electric drive from the refrigerant compressor
ensures that the automatic climate control
system continues to operate. The
electromechanically assisted steering gear
allows you to use the power steering without
reduced comfort.
Acceleration/boost function
Depending on the drive program and
accelerator pedal position, the vehicle drives
in pure electric mode or in combination with
the engine. The boost function is used when
accelerating or driving at increased or full
load. The electric motor assists the engine by
providing extra torque whenever the
accelerator pedal is depressed quickly.
Overrun mode or braking
When decelerating your hybrid vehicle, three
operating conditions are possible:
R
energy recovery (
Y
page 23) takes place
even when the vehicle is decelerating
purely in overrun mode. The electric motor
operates as a generator and stores the
recovered energy in the high-voltage
battery.
R
when the brakes are applied lightly, the
vehicle is slowed down further by the
electric motor. This increases the energy
recovery taking place. The electric motor
operates as a generator and stores the
recovered energy in the high-voltage
battery.
R
during heavy braking, the service brake is
also used to slow down the vehicle. The two
systems work together.
Urban driving
The advantages of the hybrid vehicle come
especially clearly into play when driving in the
city. Energy is recovered during the vehicle's
frequent braking.
The vehicle operates exclusively with the
electric motor at speeds of up to
approximately 20 mph (35 km/h), for
example:
R
while approaching a traffic light
R
in stop-start traffic
i
The vehicle operates exclusively with the
electric motor only if all conditions for
automatic engine switch-off are met
(
Y
page 22).
Driving on inter-urban roads
When driving on inter-urban roads, the
vehicle switches between boost phase,
constant phase and energy recovery phase.
A great deal of recovered energy may be
available, depending on the route profile. This
has a positive effect on fuel consumption and
emissions.
Highway driving
When driving on a highway, the decrease in
wasted power through recuperation has a
particularly positive effect on fuel
consumption and emissions.
