If an accident did not occur,
the pre-em ptive
measures that we retake n are reve rsed.
Sy stem limits
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 Fu
nction of 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 ®

tomatic measures af ter an accident
Depending on the type and se verity of the acci‐
dent, and depending on theve hicle's equipment,
th efo llowing measures can be implemen ted, for
ex ample:
R automatic braking (post-collision brake)
R activating the hazard warning lights
R triggering an automatic emer gency call
(/ page 344)
R switching off the engine
To restart theve hicle, switch the ignition off
and switch it back on (/ page188).
Depending on the type and se verity of the accident, it is possible
that theve hicle can
no longer be star ted.
R switching off the fuel supply
R unlocking theve hicle doors
R lowe ring the side windo ws
R displaying the emer gency guide in the multi‐
media sy stem display
R switching on the interior lighting
Fu nction of the post-collision brake
Depending on the accident situation, the post-
collision brake can minimise the se verity of a fur‐
th er collision or even avo id it.
If an accident is de tected, the post-collision
brake can implement automatic braking. When
th eve hicle has come toast andstill, the electric
parking brake is automatically applied.
The driver can cancel automatic braking bytak‐
ing thefo llowing actions:
R braking more stronglythan automatic brak‐
ing
R fully depressing the accelera tor pedal with

ECO Assist is only an aid. The driver is responsi‐
ble forke eping a safe dis tance from theve 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 venes.
The sy stem may be impaired or may not function

aids. They are not a substitute foryo ur attention
to the sur roundings and do not relie ve you of
yo ur responsibility per taining toroad traf fic la w. The driver is alw
aysre sponsible for maintaining
a safe dis tance totheve hicle in front, forve hicle
speed, for braking in good time and forst ay ing
in lane. Pay attention tothe tra ffic conditions at
all times and inter vene when necessa ry. Be
aw are of the limitations rega rding the safe use of
th ese sy stems.
Driving sy stems can neither reduce therisk of
accident if youfa ilto adapt your driving style nor
ove rride the la wsof ph ysics. They cannot alw ays
ta ke into account road, weather or traf fic condi‐
tions. In
fo rm ation on vehicle sensors and cameras Some driving and driving saf

cameras as well as radar or ultrasonic sensors
to monitor the area in front of, behind or next to
