hill or uphill gradients with slippery or loose
surfaces.
Driving on sand
When driving on sand, also observe the following
instructions:
= Select the F driving mode.
= Shis to a lower gear.
= Drive quickly to overcome the rolling resist-
ance; the vehicle may otherwise dig itself in.
= Drive in the tracks of other vehicles if possi-
ble. Make sure that the following prerequisites
are met:
- the tyre ruts are not too deep
- the sand is Nrm enough

long, steep downhill gradients.
= Activate DSR before driving downhill, if neces-
sary ( page 256). Checklist
aser dr iving oM-road
Driving oM-road places greater demands on your
vehicle than driving on normal roads. Check the
entire vehicle for damage and foreign bodies
every time aser driving oM-road. Foreign bodies in
the wheels or drivetrain can lead to imbalances
and therefore vibrations.
= If the F or G driving mode is selected:
select another driving mode.
= Deactivate DSR.
= Apply the brakes to dry them aser fording.
= Check that the service brake is working nor-
mally aser a long downhill stretch.
= Clean the following components every time

ehicle that stopped in front of you starts
up again.
= You manoeuvre, turn the steering wheel
sharply or engage reverse gear.
% If the system detects an intelligent stop inhibi-
t

or, e.g. a stop sign, the engine will not stop.
If you activate the HOLD function or engage
the park position j, the engine can be
switched oM in spite of an intelligent stop
inhibitor.
The engine will restart automatically in the follow-
ing cases:
= Y

ou engage transmission position h or k.
= You depress the accelerator pedal.
= The vehicle requires an automatic engine
start.
= You release the brake pedal.
= You release the brake pedal on a downhill gra-
dient and the vehicle does not roll.
= The vehicle rolls on a downhill gradient and
does not automatically enter glide mode at
20 km/h. Displaying the ECO start/stop function on the

= The ç symbol (yellow) appears when the
vehicle is at a standstill: not all vehicle condi-
tions for an engine stop have been met.
= Neither the è symbol nor the ç symbol
appears when the vehicle is at a standstill: an
intelligent stop inhibitor, e.g. a stop sign, has
been detected.
= The X symbol appears: the ECO start/stop
function is deactivated or there is a malfunc-
tion.
If the engine was switched oM by the ECO start/

The ECO display shows an evaluation of your driv-
ing s

tyle on the driver's display depending on the
situation. This enables you to check the ePciency
of your driving style and adjust it if necessary. The
ECO display menu shows a ball 2 that will roll forwards or backwards on a stylised road in the
dir
ection of travel according to the driving charac-
teristics.
Above and below the road, lines mark the area for
an ePcient driving style 3. Ball 2 will light up in
green if it is rolling within these lines. Outside the
lines, the ball will light up in orange.
The ECO display assesses the following criteria for
an economical driving style:
= coasting at the right times
= consistent speed
= moderate acceleration
The overall assessment of your driving style "from
start" is indicated using stars 1. It starts with
Nve empty stars, which you can Nll one aser the
other if you drive ePciently. When all Nve stars are
Nlled, a glow will appear in the background.

ECO Assist function (vehicles with 48 V on-board
electr
ical system) For plug-in hybrids, note the ECO Assist informa-
tion ( pag

e 194).
% ECO Assist is active only in drive pro-
g

rams  and A.
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 is especially the case if, for example,
you pull away again in slow-moving traPc and the
distance to the vehicle in front is very short. 1

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 the 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 vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If the traPc signs are hard to detect, e.g. due
to dirt, snow or insuPcient lighting, or
because they are covered. =
If t he 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. 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
k

eep a suPcient distance.
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 Driving and parking
193

In these cases, the desired deceleration is set by
t
he brake control system.

vehicle in front is very short.
The function will be active in the following circum-
stances:
= The function is activated in the multimedia
system (  page 196).
= The hX recuperation level is selected
( page 194).
= p manual gearshising is not activated.

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.
