Driving and driving saf
ety sy stems Note
s on driving sy stems and your responsi‐
bility Yo
ur vehicle is equipped with driving sy stems
which assist you in driving, parking and manoeu‐
vring theve hicle. The driving sy stems are only
aids. They are not a substitute foryo u paying
attention toyour sur roundings and do not relie ve
yo u of your responsibility per taining toroad traf‐
fi c la w.The driver is alw aysre sponsible for main‐
ta ining a safe dis tance totheve hicle in front, for
ve hicle speed, for braking in good time and for
st ay ing in lane. Alw ays pay attention tothe tra ffic
and inter vene if necessa ry. Be aware of the limi‐
ta tions rega rding the safe use of these 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
ety sy stems use
cameras and radar or ultrasonic sensors tomoni‐
to rth e area in front of, behind or next totheve hi‐

WARNING Risk of accident due to
re stricted de tection per form ance of vehi‐
cle sensors and cameras
If th e area around vehicle sensors or cameras
is co vered, damaged or dirty, cer tain driving
and saf ety sy stems cann otfunction cor rectly.
The reis a risk of an accident. #
Keep the area around vehicle sensors or
cameras clear of any obstructions and
clean. #
Have damage tothe bumper, radiator
grille or stone chipping in the area of
th e front and rear wind owsrepaired at a
qu alified specialist workshop. Ke
ep the areas of the cameras and sensors free
of dirt, ice and slush (/ page 229). The sensors
and cameras must not be co vered and the de tec‐
tion ranges around them must be kept free. Do
not attach additional license pla tebrac kets,
ad vertisements, sticke rs,fo ils or foils toprotect
against stone chippings in the de tection range of
th e sensors and cameras. Make sure that there
are no overhanging loads pr otru ding into the
de tection range.
In theeve nt of damage, or following a se vere
impact, ha vethe function of the sensors checked
at a qualified specialist workshop. Ha vedamage
or stone chipping in the area of the cameras
re paired at a qualified specialist workshop. Overview of driving sy

Active Brake
Assi st
Yo u can cancel a brake application of Active
Brake Assi stat any time by:
R Fully depressing the accelerator pedal or with
kickdown.
R Releasing the brake pedal.
Ac tive Brake Assi stmay cancel the brake applica‐
tion when one of thefo llowing conditions is fulfil‐
led:
R You manoeuv retoavo idthe obs tacle.
R Thereis no longer a risk of collision.
R An obs tacle is no longer de tected in front of
yo ur vehicle.
Sy stem limits
Fu ll sy stem per form ance is not available for a few
seconds af ter switching on the ignition or af ter
driving off.
The sy stem may be impaired or may not function
in thefo llowing situations:
R In sno w,rain, fog or heavy spr ay.
R Ifth e sensors are dirty, mis ted up, damaged
or co vered.
R Ifth e sensors are impaired due tointer fer‐
ence from other radar sources, e.g. strong
ra dar reflections in multi-s torey car par ks.
R If a loss of tyre pressure or a defective tyre
has been de tected and displa yed.
R In complex tra ffic situations where objects
cannot alw ays be clear lyidentified.
R If pedestrians or vehicles mo vequickly into

R The transmission is shif tedto position 005D.
R The vehicle is secured with the electric park‐

RKTRONIC Fu
nction of PARKTRONIC
PA RKTRONIC is an electronic parking assis tance
sy stem with ultrasonic sensors. The sy stem moni‐
to rs the area around your vehicle using sensors
on the front bumper and on there ar bumper.
PA RKTRONIC indicates visually and audibly the
dis tance between your vehicle and an object.
The warning ranges in front of and behind the
ve hicle are indicated bydiffere nt wa rning tones.
PA RKTRONIC is on ly an aid. It is not a substitu te
fo ryo u paying attention tothe sur roundings. Yo u
are alw aysre sponsible for safe manoeuvring,
parking and exiting a parking space. Make sure
th at there are no persons, animals or objects etc.
in the manoeuvring area while manoeuvring and
parking or exiting parking spaces.
Re quirements for automatic activation:
R The ignition is switched on.
R The parking brake has been released.
The selec ted transmission position de term ines
whe ther the front and/or rear area is monitored.
Fr ont area only:
R Forw ard gear
R Neut ral
R Transmission position 005B Fr
ont and rear area:
R Reversege ar
R Transmission position 005E
R Transmission position 005C
Re gardless of transmission position,
PA RKTRONIC automatical ly monitors the area
behind theve hicle if theve hicle begins toroll
backwards, e.g. af terst opping on an uphill gradi‐
ent.
PA RKTRONIC is deactivated at speeds abo ve
18 km/h. PARKTRONIC is reactivated at speeds
below 16km/h.
Ve hicles with trailer hitch: PARKTRONIC is
deactivated forth ere ar area when you es tablish
an electrical connection tothe trailer or toare ar
bicycle rack.
Af ter uncoupling the trailer, unplug the 7-pin plug
adap ter from the soc ket. Otherwise,
PA RKTRONIC remains deactivated forth ere ar
area.
Re mo vea detachable trailer coupling if it is no
lon gerrequ ired. PARKTRONIC measures the mini‐
mum de tection range toan obs tacle from the
bumper, not the ball nec k.

2 Measurement operational readiness indicator
3 Warning segments forth eright side of the
ve hicle
At least one segment will light up as theve hicle
approaches an obs tacle, depending on theve hi‐
cle's dis tance from the obs tacle.
In addition, warning tones are emitted. When the
dis tance tothe obs tacle is suf ficient, you will
hear an intermit tent wa rning tone. The sho rter
th e dis tance tothe obs tacle, the shor terth e fre‐
qu ency of the intermittent warning tones
becomes. When the minimum dis tance is
re ached, you hear a continuous warning tone.
The warning display for each side of theve hicle is
divided into five yellow and two red segments.
PA RKTRONIC is active if measurement opera‐
tional readiness indicator 2lights up.
Sy stem limits
PA RKTRONIC may not take thefo llowing obs ta‐
cles into account:
R obstacles bel owthe de tection range, e.g.
people, animals or objects
R obstacles ab ovethe de tection range, e.g.
ove rhanging loads, overhangs or loading
ra mp s of lor ries
The sensors must be free of dirt, ice and slush.
Otherwise, they may not function cor rectly. Clean
th e sensors regularly, taking care not toscratch
or damage them (/ page 229). Problems with
PARKTRONIC
The reis a malfunction if only there d segments of
th ewa rning display light up. In addition, a warn‐
ing tone sounds for appro ximately two seconds. If
problems pe rsist, ha vePARKTRONIC checked at
a qu alified specialist workshop.
If th ewa rning indicators are displaying implausi‐
ble dis tances, it may be due tothefo llowing cau‐
ses:
R The sensors are dirty: cleanthe sensors.
Obser vethe no tes on care of vehicle parts
(/ page 229).
R Licence plates or
other detachable parts
in the vicinity of the sensors are not cor‐
re ctly faste ned:check the licence plate or
th e de tach able parts for cor rect fit.
R In
te rference byano ther source of radio or
ultrasound waves:check the function of
PA RKTRONIC at ano ther location.
Deactivating/activating PARKTRONIC #
Press theé button.
If PA RKTRONIC is deactivated, the indicator
lamp of theé button lights up. Re
versing camera Fu
nction of there ve rsing camera
The reve rsing camera is located next totheta il‐
ga te handle and is pr otected from raindrops and
dust bymeans of a flap. When there ve rsing cam‐
era is activated, this flap opens (/ page153).
The flap closes again when you ha veended the
manoeuvring process or you swit choff the
engine. Driving and parking
