Driving and driving saf
ety sy stems Driving sy
stems and your responsibility 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 aids
and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times
and inter vene when necessa ry. Be aware of the
limitations rega rding the safe use of these sys‐
te ms. Fu
nction of thera dar 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 thera diator grille. Keep these
parts free of dirt, ice and slush . The sensors
must not be co vered, forex ample bybicycle
ra ck s, ove rhanging loads or radar-reflecting
st icke rs.Fo llowing an impact and in theeve nt of associated dama
ge, which may not be visible, to
th e bumpers or radiator grille, ha vethe function
of thera dar sensors checked at a qualified spe‐
cialist workshop. The driver assis tance sy stem
may no longer workproperly. Overview of driving sy

nctions of Parking Assist PARKTRONIC Pa
rking Assist PARKTRONIC is an electronic
parking assi stance sy stem with ultrasound. It
monitors the area around your vehicle using six
sensors 1inthe front bumper and six sensors
in there ar bumper. Parking Assist PARKTRONIC
indicates visually and audibly the dis tance
between your vehicle and an object.
Pa rking Assist PARKTRONIC is on lyan aid. It is
not a substitute foryo ur attention tothe sur‐
ro undings. The responsibility for safe manoeu‐
vring and parking remains with you. Make sure
th at there are no persons, animals or objects in th
e manoeuvring area while manoeuvring and
parking in/exiting parking spaces.
In thest andard setting, an intermit tent wa rning
to ne sounds from a di stance of appr oximately
0.3 m toan obs tacle. A continuous tone sounds
from a di stance of appr oximately 0.2 m. You can
set thewa rning tone in the multimedia sy stem
so that it will sound earlier at a greater dis tance
of appr oximately 1.0 m (→ page 220).
If Pa rking Assist PARKTRONIC is deacti vated,
Pa rking Pilot is una vailable.

Pa ssive side impact pr otection
Pa ssive side impact pr otection is an additional
Pa rking Assist PARKTRONIC function which
wa rnsth e driver about obs tacles at the side of
th eve hicle. A warning is issued when obs tacles
are de tected between the front and rear de tec‐
tion range. In order for an object tobe de tected, th
e sensors in the front and rear bumper must
de tect the object while you are driving past it.
During the parking procedure or manoeuvring,
objects are de tected as theve hicle drives past.
If yo usteer in the direction of a de tected obs ta‐
cle and there is a risk of a lateral collision, a
wa rning is issued. The lateral segments light up
