distance totheev ent ahead as follo ws:
R Afew segments light up: theev ent ahead is
near.
R Many segments light up: theev ent ahead is
fur ther awa y.
When theve hicle nears theeve nt, ECO Assist will
calculate the optimal speed for maximum fuel
economy and recuperative energy based on the
distance, speed and gradient. The Foot off the
accelerator 3message appears in the Instru-
ment Displa y.The /rst segments in front of the
ve hicle will turn green. The remaining segments
will initially st aywhite. If youta ke your foot o. the
accelerator pedal in good time, there maining seg-

until theev ent shown is reached. The driv etra in
will be set for maximum fuel econom y.Re cupera-
tion will charge the batter y.Re cuperation will be
adap tedto the selected drive prog ram.
The event will be shown for a short time aTer it
has been passed. If there is no response tothe
Foot off the accelerator prompt,th e segments
will remain white. If
th eev ent in volves a vehicle in front, all seg-
ments will immediately turn green once there is a
re sponse totheFoot off the accelerator prompt.
Fo r active ECO Assist in drive prog ram ;,
symbol 3will appear on the inst rument display
and on the head-up display beside transmission
position 005B. Symbol 3will also appear when the

If th e system does not inter vene during theev ent

ECO Assist can function even more precisely if
th ero ute is adhered towhen routeguidance 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 the 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. The driver must be ready tobrake at all times ir
respecti veof whe ther the system inter-
ve nes.
The system may be impai red or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsu1cient illu-
mination 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 Ifth ere is dirt on the windscreen in the area of
th e multifunction camera or the camera is
misted up, damaged or obscured.
R Ifro ad signs are hard todetect, e.g. due to
dirt, snow or insu1cient lighting, or because
th ey are obscured.
R Ifth e information on the navigation system's
digital map is incor rect or out of date.
R If signs are ambiguous, e.g. road signs in road-
wo rks or in adjacent lanes. 178 178

If BAS is malfunctioning, the braking distance
in an emer gency braking situation is
increased. #
Dep ress the brake pedal with full forc e in
emer gency braking situations. ABS pre-
ve nts the wheels from locking. The Brake Assist System (BAS) supports
your

If yo u depress the brake pedal quickl y,BAS is
activated:
R BAS automatically boosts the brake pressure.
