possibilities touse data collected from theve hicle
to identify theow ner or driver, such as the licence

Therefore, data generated or processed bycont rol
units may be attributable toa person or, under
cer tain conditions, become attributable toa per-

When
theve hicle nears an event, ECO Assist will
calculate the optimal speed for minimal energy
consum ption based on the distance and speed.
"Foot o. the accelerator" recommendation 3will
appear on the inst rument displa y.
If yo uta ke your foot o. the accelerator pedal in
good time, there maining segments on the display
will successively turn green until theeve nt sh own
is reached. The driv etra in will be set for minimal
energy consum ption. The vehicle will recuperate
autonomously and thus charge the high-voltage
batter y.
% You can also manually increase or reduce
re cuperation. Ho wever, ECO Assist is availa-
ble only in thehà setting (/ page 156).
If th ere is no response to"Foot o. the accelera-
to r" recommendation 3,the segments will
re main white.
The event will be shown for a short time aTer it
has been passed.
If th eev ent in volves a vehicle in front, all seg-
ments will immediately turn green once there is a
re sponse to"Foot o. the accelerator" prom pt3 . If ECO Assist cann
otidentify a recommendation
fo r adjusting the driving style forth eev ent ahead,
no thing will be displa yed. The system will be pas-
sive.

ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available without
active route guidance. Not all information and
tra1c situations can be fore seen. The quality
depends on theav ailable map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. You must be ready tobrake at all times ir re-
specti veof whe ther the system is active.
The system may be impaired or may not function
in thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsu1cient
illumination of thero ad, highly variable shade
conditions, rain, sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming tra1c,
direct sunlight or re0ections. R
