ECO display function
The ECO display summarises your driving charac-
t
eristics from the start of the journey to its com-
pletion and assists you in achieving the most eco-
nomical driving style.
You can inOuence consumption by doing the fol-
lowing:
= driving with particular care.
= Vehicles with automatic transmission: driving
in drive program .
= Vehicles with manual transmission: driving in
drive program A.
= following the gearshis recommendations. The lettering in the segment will light up brightly,
t
he outer edge will light up and the segment will
Nll up when the following driving style is adopted:
= 1 Steady speed
= 2 Gentle deceleration and rolling
= 3 Moderate acceleration
The lettering in the segment will be grey, the outer
edge will be dark and the segment will empty
when the following driving style is adopted:
= 1 Fluctuations in speed
= 2 Heavy braking
= 3 Sporty acceleration
The ECO display will show you when you have
driven economically:
= The three segments will Nll up completely at
the same time
= The edges around all three segments will light
up
The additional range achieved as a result of your
driving style in comparison with a driver with a
very sporty driving style will be shown in the centre of display
4. The r ange displayed does
not indicate a Nxed reduction in consumption. Regenerative brake system (plug-in hybrid)
Function of the regenerative brake system
Depending on t
he selected recuperation level, the
electric motor is operated as an alternator when
in overrun mode and during braking in order to
charge the high-voltage battery while driving. As
soon as you take your foot oM the accelerator
pedal when the vehicle is in motion and in trans-
mission position h, recuperation in overrun
mode is initiated.
The higher the recuperation, the more sharply the
vehicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
tery.
The deceleration in overrun mode may not be suf-
ficient depending on the driving conditions.
Decelerating to a standstill is not possible. Also
brake with the service brake if necessary. Always
adapt your speed to the driving conditions and
keep a suPcient distance. Driving and parking
169

The recuperative brake system has the following
c
haracteristics:
= supports braking with electronically controlled
brake force boosting
= converts the kinetic energy of the vehicle into
electric energy
% If you brake hard, the mechanical brake is
also used. This means t
hat the maximum
recuperative energy cannot be recovered. The
more you drive and brake in an anticipatory
manner, the more ePciently energy can be
recuperated.
System limits
The br
aking eMect of the electric motor during
recuperation in overrun mode may be reduced or
may not be available at all in the following situa-
tions:
= when the high-voltage battery charge level
increases
= if the high-voltage battery is not yet at a nor-
mal operating temperature In these cases, the desired deceleration is set by
t

he brake control system.
Manually setting recuperative deceleration
% In the Î dr
ive program, you can use the
steering wheel gearshis paddles to manually
adjust the intensity of recuperation in overrun
mode. %
When the vehicle is started again or transmis-
sion position h is eng

aged again, the stand-
ard setting is automatically set. The following recuperation levels are available:
= hX Int

elligent, anticipatory recuperation
with ECO Assist (standard setting)
( page 171)
= hq No recuperation: the vehicle rolls freely
= h Normal recuperation
= hX Increased recuperation: strong deceler-
ation in overrun mode, e.g. for driving on
downhill gradients
= hXX Maximum recuperation: maximum
deceleration in overrun mode 
To increase recuperation: br
ieOy pull gearshis
paddle 1. 
To reduce recuperation: br
ieOy pull gearshis
paddle 2. 
Standard setting: pull and hold g
earshis pad-
dle 1 or 2 or engage transmission position
h again. 170

%
The following function is country-dependent
and a

vailable only in conjunction with an inte-
grated hard drive navigation system.
ECO Assist is active only in drive programs A,
Î, Ï and , and onl

y in transmission
positions h or hX. Permanent manual gear-
shising p must be switched oM ( page 181).
ECO Assist analyses data for the vehicle's expec-
ted route. This allows the system to optimally adjust the driving style for the route ahead, save
fuel and r
ecuperate.
ECO Assist is displayed on the Assistance
menu( page 276). 1

The f
ollowing events 1 can be detected and dis-
played for the route section ahead:
= Vehicle in front
= Speed limit
= Downhill and uphill gradients
= Junctions and roundabouts
= Bends
The segments of distance display 2 show the
distance to the event ahead as follows:
= A few segments light up: the event ahead is
near. Driving and parking

=
Man y segments light up: the event ahead is
further away.
If ECO Assist is active, the "Foot oM the accelera-
tor" symbol 3 will appear on the instrument dis-
play and on the head-up display beside the trans-
mission position display.
When the vehicle nears an event, ECO Assist will
calculate the optimal speed for minimal energy
consumption based on the distance, speed and
gradient. The "Foot oM the accelerator" symbol 3
will appear on the instrument display.
If you take your foot oM the accelerator pedal in
good time, the remaining segments on the display
will successively turn green until the event shown
is reached. The drivetrain will be set for minimal
energy consumption. The vehicle will recuperate
autonomously and thus charge the battery.
% You can also manually increase or reduce the
r
ecuperation in drive program Î. However,
ECO Assist is available only in the hX
setting (  page 170).
If there is no response to the "Foot oM t
he accel-
erator" prompt 3, the segments will remain
white. The event will be shown for a short time
aser it
has been passed.
If t

he event involves a vehicle in front, the symbol
will be shown in green as soon as there is a
response to "Foot oM the accelerator" prompt 3.
If the system does not intervene during the event
ahead, nothing will be displayed. The system will
be passive.
System limits
ECO Assist can function even more precisely if
the route is adhered to when route guidance is
active. The basic function is also available without
active route guidance. Not all information and
traPc situations can be foreseen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
for keeping a safe distance from the vehicle in
front, for vehicle speed and for braking in good
time. The driver must be ready to brake at all
times, irrespective of whether the system inter-
venes. The system may be impaired or may not function
in t he following situations:
= If visibility is poor, e.g. due to insuPcient illu-
mination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= If there is dirt on the windscreen in the area of
the multifunction camera or the camera is
misted up, damaged or obscured.
= If road signs are hard to detect, e.g. due to
dirt, snow or insuPcient lighting, or because
they are obscured.
= If the information on the navigation system's
digital map is incorrect, insuPcient or out of
date.
= If signs are ambiguous, e.g. road signs in road-
works or in adjacent lanes. 172

Function of the route-based operating-mode strat-
egy (plug-in h
ybrid) %
The following function is country-dependent
and a

vailable only in conjunction with an inte-
grated navigation system.
The route-based operating-mode strategy is active
onl
y in drive programs A and . When
route guidance is active, data on the planned
route is analysed. This function can be activated
and deactivated in the multimedia system
(  page 295).
If the function is active, data on the further course
of the route is evaluated. This includes e.g. road
type, speed limitations and altitude data.
The hybrid system then adapts the operating
strategy to the further course of the route:
= Use of electrical energy and the combustion
engine are adapted.
= State of charge of the high-voltage battery is
controlled accordingly.
= Electrical energy is reserved especially for
electric mode, e.g. urban route sections. =
The v
ehicle automatically selects the operat-
ing mode.
When the route-based operating-mode strategy is
activated, the energy Oow display shows the sta-
tus of the function as !

=
Balance be tween traction and stability
= The selection of the matching drive type by
the hybrid system depends on the driving con-
ditions and the distance (plug-in hybrid)
