The recuperative brake system has the following
characteristics: = 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.

ECO Assist function
%
The following function depends on the equip-
ment and t

he country.
ECO Assist analyses data for the vehicle's expec-
t
ed route. This allows the system to optimally
adjust the driving style for the route ahead, save
fuel and recuperate. If the system detects an
event ahead and the vehicle nears the event, ECO
Assist will calculate the optimum speed for maxi-
mum fuel economy and recuperative energy
based on the distance, speed and downhill gradi-
ent.
If the deceleration provided by ECO Assist is not
suPcient, you must also brake with the service
brake. This applies in particular if, for example,
you pull back into traPc and the distance to the
vehicle in front is very short. The function will be active in the following circum-
s

tances:
= The function is activated in the multimedia
system (  page 224).
= The hX recuperation level is selected
( page 222).
= p manual gearshising is not activated.
= Drive program C is not selected. 1

If a route event that can be dealt with more eP-
cientl
y by adjusting your driving style is detected ahead, corresponding symbol
2 and t
he ý
symbol will be displayed in grey.
If you release the accelerator pedal, the ý
symbol will turn green and recuperation in over-
run mode will be initiated. If the deceleration is
not suPcient, also apply the service brake.
The display will disappear as soon as ECO Assist
cannot identify any further recommendations
from the route ahead. The following route events can be detected by

System limits
If t
he calculated route is adhered to when route
guidance is active, ECO Assist will operate with
greater accuracy. The basic function is also availa-
ble without active route guidance. Not all informa-
tion 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 system may be impaired or may not function
in t
he following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination 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 vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If the radar sensors are dirty or damaged.
= If the traPc signs are hard to detect, e.g. due
to dirt, snow or insuPcient lighting, or
because they are covered.
= If the information in the navigation system's
digital map is incorrect or out of date.
= If signs are ambiguous, e.g. road signs in road-
works or in adjacent lanes. Activating or deactivating ECO Assist

Activate or deactivate the function. 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
under t
he following conditions:
= Drive program n is selected.
= The "route based" option ( page 227) is
selected for drive program n in the
DYNAMIC SELECT menu.
= Route guidance is active.
= The state of charge of the high-voltage battery
is suPcient. 224
Driving and parking

If the function is active, data on the further course
of t
he 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 vehicle automatically selects the operat-
ing mode. Function of the haptic accelerator pedal (plug-in
h
ybrid) The haptic accelerator pedal has an additional
point of r
esistance followed by increased pedal
resistance to help you drive in all-electric mode.
Characteristics of the additional point of resist-
ance:
= Available only in drive program

= Comf
ortable and economical driving
= Balance between traction and stability
= Recommended for all road conditions

tion h or k, the vehicle may accelerate
sharply. 
If you engage the transmission position

Nrmly and do not accelerate at the same
time. &
WARNING Risk of accident and injur
y due
to leaving children unattended in the vehi-

If children are les unatt
ended in the vehicle,
they could, in particular:
= open doors, thereby endangering other
persons or road users.
= get out and be struck by oncoming traPc.
= operate vehicle equipment and become
trapped, for example.
In addition, the children could also set the
vehicle in motion by, for example:
= releasing the parking brake.
= changing the transmission position.
= starting the vehicle. 
Never leave children unattended in the
v
ehicle. 
When leaving the vehicle, always take the
k
ey with you and lock the vehicle.
