The active components of the drive sy stem are
highlighted in the energy flow displa y.The
energy flow between the individual components
is shown in colour.
The energy flow is shown in dif fere nt colou rs
depending on the operating status:

moderate accele ration
R blue: recuperation (cha rging the high-voltage

generative brake sy stem Fu
nction of there ge nerative brake sy stem
Depending on the selected recuperation le vel,
th e electric mo tor is operated as an alternator
when in overrun mode and during braking in
order tocharge the high-voltage battery while
driving. As soon as youre lease the accelerator
pedal when theve hicle is in motion, recupera‐
tion in overrun mode is initiated.
The higher there cuperation, the more sharply
th eve hicle is braked when coasting and the
more electrical energy is fed into the high-volt‐
age batter y.

perati veenergy can be used.
Sy stem limits
The braking ef fect of the electric mo tor during

WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. Note
s on driving with a roof load, trailer or
fully laden vehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu‐
pied vehicle, theve hicle's driving and steering
ch aracteristics change. Yo
u should bear thefo llowing in mind:
R Do not exceed the permissible roof load and
to wing capacity. Also obser vethete ch nical
da ta inthe printed Owner's Manual.
R Evenly distribute thero of load, and place
heavy objects at the bottom. Also comply
with the no tes on loading theve hicle
(/ page 106).
R Drive attentivel y,and avoid sudden lypulling
aw ay, braking and steering as well as rapid
cornering.
Note s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
conside rably or result in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front To
remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page 328).15 4
Driving and pa rking

Note
s on driving through water on the road
sur face
Wa ter which has entered theve hicle can damage
th e drive sy stem, electrics and transmission.
Obser vethefo llowing if you must drive thro ugh
wate r:
R The wate r,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at walking pace at mos t;wa ter can oth‐
erwise enter theve hicle interior.
R Vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible dep thofthewa ter.
The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention to
th e traf fic conditions until braking po wer has
been fully restored. ECO display function
The ECO display summarises
your driving char‐
acteristics from thest art of the journey toits
completion and assists you in adopting an ef fi‐
cient driving style to maximise range. Yo
u can influence energy consum ption bydoing
