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 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 Safely transporting
children in theve hicle Alw

tential risks and avoid dangers if chil‐
dren are tr avelling in theve hicle
(/ page 54).
Be diligent
Bear in mind that negligence when securing a
ch ild in thech ild restra int sy stem may ha veseri‐
ous consequences. Alw ays be diligent in secur‐
ing a child carefully before everyjou rney.
To impr oveprotection forch ildren younger than
12 years old or under 1.50 m in height,
Mercedes-Benz recommends you obse rvethe
fo llowing information:
R Alw ays secure thech ild in a child restra int
sy stem suitable forth is Mercedes-Benz vehi‐
cle.
R The child restra int sy stem must be appropri‐
ate tothe age, weight and size of thech ild.
R The vehicle seat must be suitable forfitting a
ch ild restra int sy stem (/ page 58).
Ac cident statistics show that children secured
on there ar seats are general lysafer than chil‐
dren secured on the front seats. Forth is reason, Occupant saf

Detection range of the sensors
If se veral consecutive kicking mo vements are
not successful, waitte n seconds.
Sy stem limits
The sy stem may be impaired or may not function
in thefo llowing cases:
R The sensors are dirty, e.g. due toroad salt or
sn ow.
R The kicking mo vement is made using a pros‐
th etic leg. The
tailgate can open or close unin tentional lyin
th efo llowing situations:
R A person's arms or legs are moving in the
sensor de tection range, e.g. when polishing
th eve hicle or picking up objects.
R Objects are mo ved or placed behind theve hi‐
cle, e.g. tensioning stra ps or luggage.
R Clamping stra ps, tarp aulins or other co ver‐
ings are pulled overth e bumper.
R A pr otective mat with a length reaching over
th e boot sill down into the de tection range of
th e sensors is used.
R The pr otective mat is not secured cor rectl y.
R Workis being done on the trailer hitch, trail‐
ers or rear bicycle rack s.
Deactivate the function of theke y (/ page74 )
or do not car rytheke y about your person in
such situations. Limiting

tivating the opening angle limiter
Yo u can limit the opening angle of theta ilgate in
th eto p half of its opening range up toa point
shortly before the end position. #
Stop the opening procedure of theta ilgate at
th e desired position. #
Press and hold the closing button on theta il‐
ga te until you hear a sho rtacoustic signal.
The opening angle limiter will be activated.
The tailgate will then stop in thestored posi‐

TEReduced battery life due tofre‐
qu ent short-dis tance trips The
12V battery may not be suf ficiently

short-dis tance trips. This reduces the life of
th e batter y. #

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 108).
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

WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the

de tects this. #
Alw ays adapt your driving style to suit
th e cur rent road and weather condi‐
tions. When driving with a trailer, ESP
®
can stabilise
yo ur vehicle if the trailer begins toswer vefrom

speeds of 65 km/h.
R Slight swerving is reduced bymeans of a tar‐
ge ted, individual brake application on one
side.
R Intheeve nt of se vere swerving, the engine
output is also reduced and all wheels are

nction of route-based speed adaptation
When Active Dis tance Assi stDISTRONIC is acti‐
va ted, theve hicle speed will be adap ted accord‐
ingly tothero ute events ahead. Depending on th
e drive prog ram selected, theve hicle negoti‐
ates a route event ahead in an economical, com‐
fo rtable or dynamic manner. When thero ute
eve nt has been passed, theve hicle accelerates
again tothestored speed. The set dis tance to
th eve hicle in front, vehicles de tected ahead and
speed restrictions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia sy stem
(/ page 202).
The following route events are take n into
account:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
Information )
% When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed. Driving and parking

Also,
the speed is reduced if the turn signal indi‐
cator tochange lanes is swit ched on and one of
th efo llowing situations is de tected:
R Turning off at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts
and traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
When route guidance is active, thefirs t speed

ro ute is confirmed and fur ther speed adjustment
is activated.
Speed adap tation is cancelled in thefo llowing
cases:
R Ifth e turn signal indicator is switched off
before thero ute event.
R Ifth e driver depresses the accelerator or
brake pedal during the process. Sy

Ro ute-based speed adap tation does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
