the sensors adjust automatically while a cer-
tain distance is being driven aser the vehiclehas been delivered or
aser r
epairs. Full sys-
tem eMectiveness is not reached until the end
of this teach-in process.
= Brake pads, brake disks and tyres that are
either new or have been replaced only achieve
optimum braking eMect and grip aser several
hundred kilometres of driving. Compensate for
the reduced braking eMect by applying greater
force to the brake pedal. Notes on driving
&
WARNING Risk of accident due t
o objects
in the driver's footwell
Objects in the driver's footwell may impede
pedal tr
avel or block a depressed pedal.
This jeopardises the operating and road safety
of the vehicle. 
Stow all objects in the vehicle securely
so t
hat they cannot get into the driver's
footwell. 
Always Nt t
he Ooor mats securely and as
prescribed in order to ensure that there
is always suPcient room for the pedals. 
Do not use loose Ooor mats and do no
t
place Ooor mats on top of one another. &
WARNING Risk of accident due t
o incor-
rect footwear
Incorrect footwear includes, for example: = shoes wit

h platform soles
= shoes with high heels
= slippers
There is a risk of an accident. 
Always wear suitable footwear so that
y

ou can operate the pedals safely. &
WARNING Risk of accident if t
he vehicle is
switched oM while driving
If you switch oM t
he vehicle while driving,
safety functions are restricted or no longer
available. Driving and parking
199

This may
aMect t he power steering system and
the brake force boosting, for example.
You will need to use considerably more force
to steer and brake, for example. 
Do not switch oM t
he vehicle while driv-
ing. &
WARNING Risk of accident due t
o the
brake system overheating
If you leave your foot on the brake pedal when
dr
iving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail. 
Never use the brake pedal as a footrest. 
Do not depress the brake pedal and the
acceler
ator pedal at the same time while
driving. *
NOTE Damag
e to the vehicle due to not
observing the maximum permitted head-
room clearance If the vehicle height is greater than the maxi-
mum per
mitted headroom clearance, the roof
and other parts of the vehicle may be dam-
aged. 
Observe the signposted headroom clear-
ance. 
If the vehicle height is greater than the
per
mitted headroom clearance, do not
enter. 
Observe the changed vehicle height with
add-on r
oof equipment. Notes on driving with a roof load, trailer or fully
laden v
ehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle's driving and steering
characteristics change. You should bear the following in mind:
= Do no

t exceed the permissible roof load and
towing capacity. Also observe the technical
data in the printed Owner's Manual.
= Evenly distribute the roof load, and place
heavy objects at the bottom. Also comply with
the notes on loading the vehicle
( page 134).
= Drive attentively, and avoid suddenly pulling
away, braking and steering as well as rapid
cornering.
Notes on driving on salt-treated roads
The braking eMect is limited on salt-treated roads.
Therefore, observe the following notes: = due to salt build-up on the brake disks and
brakepads, the braking distance can increase
considerably or result in braking only on one
side
= maintain a much greater safe distance to the
vehicle in front 200
Driving and parking

To remove salt build-up:
=
br
ake occasionally while paying attention to
the traPc conditions
= carefully depress the brake pedal at the end of
the journey and when starting the next jour-
ney
Notes on aquaplaning
Aquaplaning can take place once a certain
amount of water has accumulated on the road
surface.
Observe the following notes during heavy precipi-
tation or in conditions in which aquaplaning may
occur:
= reduce speed
= avoid tyre ruts
= avoid sudden steering movements
= brake carefully
% Also observe the notes on regularly checking
wheels and tyr

es ( page 429). Notes on driving through water on the road sur-
f

ace
Water which has entered the vehicle can damage
the drive system, electrics and transmission.
Observe the following if you must drive through
water:
= The water, when calm, may only reach the
lower edge of the vehicle body.
= Drive at walking pace at most; water can oth-
erwise enter the vehicle interior.
= Vehicles travelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible depth of the water.
The braking eMect of the brakes is reduced aser
fording. Brake carefully while paying attention to
the traPc conditions until braking power has been
fully restored. Function of rear axle steering
%
This function is an on-demand feature
(  pag

e 26). The rear axle steering is an electromechanical
auxiliar
y steering on the rear axle which adjusts
the steering of the rear wheels according to the
position of the front wheels, depending on the
speed. This results in greater manoeuvrability and
improved driving stability, e.g. when cornering.
Rear axle steering has the following characteris-
tics:
= reduced steering eMort and turning circle
resulting in reduced parking eMort
= improved driving stability, e.g. when cornering
= more direct steering resulting in improved
handling of the vehicle
Observe the notes on snow chains and snow
chain mode ( page 430). Driving and parking

ECO display function
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
direction 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 dr
iving 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.
% You can call up the ECO display function via
t
he Classic menu ( page 321). Recuperative brake system
Function of the regenerative brake system
Depending on t
he selected recuperation level, the
electric motors are 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
v
ehicle 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. Also
brake with the service brake if necessary. Always
adapt your speed to the driving conditions and
keep 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. 202
Driving and parking

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
the brake control system.
Manually setting recuperative deceleration
You can use the steering wheel gearshis paddles
to manually adjust the intensity of recuperation in
overrun mode. %
When the vehicle is started again, h is aut
o-
matically set as the recuperation level.
The following recuperation levels are available: = hX Int

elligent and anticipatory recupera-
tion with ECO Assist (  page 203)
= hd No recuperation: the vehicle coasts,
rolls freely

To increase recuperation: br
ieOy pull gearshis
paddle 1. 
To reduce recuperation: br
ieOy pull gearshis
paddle 2. 
To select hX: pull and hold g
earshis pad-
dle 1 or 2.

tion display. ECO Assist
ECO Assist function
EC

O Assist is only an aid. It is not a substitute for
you paying attention to your surroundings and
does not relieve you of your responsibility pertain-
ing to road traPc law. The driver is responsible for
keeping a safe distance from the vehicle in front,
for vehicle speed and for braking in good time. Driving and parking
203

&
WARNING Risk of accident if EC O Assist
does not provide suPcient deceleration
ECO Assist only brakes your vehicle when you
t
ake your foot oM the gas pedal. If vehicles are
detected late, e.g. aser tight curves, or if you
do not react immediately to the ECO Assist
display, the deceleration may not be suPcient.
React promptly to the ECO Assist recom-
mendation and t

ake your foot oM the gas
pedal. 
Adjust your speed to the driving condi-
tions and maint

ain a suitable distance
from the vehicle in front. 
Brake the vehicle yourself and/or take
e

vasive action. ECO Assist is active only in
hX
(  pag

e 203).
Depending on the vehicle's equipment, ECO
Assist analyses data for the vehicle's expected
route. This allows the system to optimally adjust
the driving style for the route ahead, use minimal
energy and recuperate as much as possible. If the
system has detected an event ahead or a vehicle in front and the vehicle is approaching the event,
EC
O Assist will calculate an optimised speed pro-
Nle based on the distance, speed and available
route information.
If you release the accelerator pedal in this case,
intelligent recuperation will start in overrun mode.
If ECO Assist has detected a vehicle travelling in
front or a stationary vehicle ahead, it can brake
your vehicle to a standstill. This may be the case,
for example, at the end of a traPc jam or if the
detected vehicle ahead stops in front of you.
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.
Depending on the vehicle equipment and at low
speeds, e.g. in a multi-storey car park or on play
streets, no adjustment is made for stationary
vehicles and therefore there is no display. 1

The ECO Assist display is hidden again in the fol-
lo wing cases:
= You do not react to the ECO Assist recommen-
dation for a long time.
= ECO Assist cannot identify any further recom-
mendations from the route ahead.
In addition to a vehicle in front ¥, ECO Assist
can detect the following route events 2 depend-
ing on the vehicle's equipment:
c Roundabout
¡ S-bend
¢ Sharp bend
£ T-junction
¤ Downhill gradient
¦ Speed limit
ECO Assist can also react to other intersections
or junctions if y
ou activate the turn signal indica-
tor in good time.
% On roads with an obligation to drive in a lane
as f

ar to the right as possible, vehicles driving
in the lane to your les will also be recognised
as vehicles ahead of you. To enable ECO Assist to react to future route
e

vents, the equipment-dependent speed adapta-
tion functions of Active Distance Assist must be
active ( page 258).
System limits
If the 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 will be available aser dr
iving oM,
as soon as the sensor check is completed.
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 the windscreen is dirty in the vicinity of the
multifunction camera. =
If t
he multifunction camera is misted up, dam-
aged 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 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.
= If the radar sensors are dirty or obscured.
= When you drive on roads with steep uphill or
downhill gradients.
= If there are narrow vehicles in front, such as
bicycles or motorcycles.

Function of the haptic accelerator pedal
The haptic accelerator pedal features an addi-
tional point of r
esistance to help you drive as eP-
ciently as possible in drive program .Range maximisation
Range maximisation function
The r

ange maximisation function enables a maxi-
mum range gain. To achieve this, the function par-
tially or completely switches oM convenience sys-
tems that are not relevant to driving and activates
ePciency-enhancing driving functions.
The range maximisation function controls the
restrictions of the following function groups: = Climate control
- Restricting climate control functions and
deactivating front windscreen, rear window
and mirror heaters
= Interior
- Switching oM ambient lighting, displays
and certain charging functions
= Seating comfort -
Deactiv
ating the steering wheel heater,
seat heating and ventilation and deactivat-
ing the massage function
= ECO drive functions
- Changing to the  drive program, acti-
vating ECO Assist and the hX recu-
peration level
If necessary, you can deactivate the restrictions
of individual function groups again. This will
reduce the maximum range gain by the value
speciNed for the function group.
If you switch on a deactivated function while
range maximization is activated, all restrictions of
the corresponding function group will be removed
and the maximum range gain will be reduced
accordingly. For example, if you switch on the
seat heating again, all restrictions of the "Seating
comfort" function group will be deactivated.
This does not apply to the "ECO driving functions"
group, as the range gain in this case depends
mainly on your personal driving style. The activa-
ted ECO driving functions help you to drive in an
energy-ePcient manner. The speciNed range gain
for the ECO drive functions can be achieved only if you observe the driving instructions and recom-
mendations displa yed and drive without kickdown.
