Re
versing the PRE- SAFE®
sy stem measures If an accident did not occur,
the pre-em ptive
measures that we retak en are reve rsed.
Yo u will need toper form certain settings your‐
self. #

The locking mechanism releases. Fu
nction of PRE-SAFE ®
PLUS (anticipatory
occupant pr otection plus) PRE-
SAFE®
PLUS can de tect cer tain impacts,
particular lyan imminent rear impact, and take
pre-em ptive measures toprotect theve hicle
occupants. These measures cannot necessarily
pr eve nt an imminent impact.
PRE-SAFE ®
PLUS can implement thefo llowing
measures independently of each other:
R Tightening the seat belts on the driver's seat
and front passenger seat.
R Activating there ar hazard warning lights at a
higher flashing frequenc y. R
Increasing brake pressure when theve hicle
is stationar y.This brake application is cancel‐
led automatically when theve hicle pulls
aw ay.
If an accident did not occur, the pre-em ptive
measures that we retake n are reve rsed.
Sy stem limitations
The sy stem will not initiate any action in thefo l‐
lowing situations:
R when reve rsing
or
R when theve hicle is towing a trailer and there
is a risk of a rear impact
The sy stem will not initiate any braking applica‐
tion in thefo llowing situations:
R whilst driving
or
R when entering or exiting a parking space
while using Active Parking Assist Information on PRE-
SAFE®
Impulse Side If an imminent side impact is de
tected, PRE-
SA FE®
Impulse Side can pre-emptively mo vethe
front seat vehicle occupant's upper body
to wa rdsth e cent reoftheve hicle. It does this by
ra pidly inflating an air cushion in the outer seat
side bols ter of the seat backrest on the side on
which the impact is anticipated. This increases
th e dis tance between the door and theve hicle
occupant.
If PRE-SAFE ®

is faulty, thePRE-SAFE impulse side inoperative

in front of theve hicle depending on the dis tance
to theeve nt ahead:
R Few segments: theeve nt ahead is nea r.
R Many segments: theev ent ahead is fur ther

When theve hicle nears theeve nt, ECO Assi st
will calculate the optimal speed for maximum
fuel economy and recuperati veenergy based on
th e dis tance, speed and downhill gradient. The

front of theve hicle will become green. The
re maining segments will initially stay white. If
th e driver lifts off the accelerator pedal in good
time, there maining segments on the display will
turn green until theeve nt shown is reached. The
driv etra in will be set for maximum fuel econom y.

The event will be shown for a short time af ter it

If th e sy stem does not inter vene du ring the

te m is passive.
ECO Assist is active only in drive programs ;
and A.
Sy stem limitations
ECO Assist can function more precisely if the
ro ute is main tained when route guidance is
active. The basic function is also available with‐
out active route guidance. Notall information
and traf fic situations can be fore seen. The qual‐
ity depends on the map data. ECO Assist is only an aid. The driver is
responsi‐
ble forke eping a safe dis tance totheve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all
times ir respective of whe ther the sy stem inter‐
ve nes.
The sy stem may be impaired or may not function
in thefo llowing situations:
R If visibility is poor (e.g. due toinsuf ficient illu‐
mination of thero ad, high lyvariable shade
conditions, rain, sno w,fog or heavy spr ay).
R Ifth ere is glare (e.g. from oncoming traf fic,
di re ct sunlight or reflections).
R Ifth ere is dirt on the windscreen in the vicin‐
ity of the multifunction camera or the camera
is mis ted up, damaged or obscured.
R Ifth e tra ffic signs are hard todiscern (e.g.
due todirt or snow or insuf ficient lighting, or
because they are obscured).
R Ifth e information on the navigation sy stem's
digital map is incor rect or out of da te.
R Ifth e signs are ambiguous (e.g. traf fic signs
in roadwor ksor in adjacent lanes). 202

ur vehicle is equipped with driving sy stems
which assist you in driving, parking and manoeu‐
vring theve hicle. The driving sy stems are aids
and do not relie ve you of your responsibility per‐
ta ining toroad traf fic la w.Pay attention tothe traf
fic conditions at all times and inter vene
when necessa ry. Be aware of the limitations
re ga rding the safe use of these sy stems. Information about
radar senso rs Some driving and driving sa
fety sy stems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. Keep these
parts free of dirt, ice and slush (/ page545).
The se nsors mu stnot be co vered, forex ample

or foils toprotect against stone chipping. In the
eve nt of dama getothe bumpers or radiator
grille, or following a collision impacting the
bumpers or radiator grille, ha vethe function of
th era dar sensors checked at a qualified special‐
ist workshop. The driving sy stems and driving

or insuf ficient tyre traction, the wheels are
pr eve nted from lo cking.
R Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.
