TEDama getotheve hicle In
thefo llowing situations, in particular, there
is a risk of damage totheve hicle:
R theve hicle becomes grounded, e.g. on a
high kerb or an unpa vedro ad
R theve hicle is driven toofast over an
obs tacle, e.g. a kerb, speed bump or pot‐
hole
R a heavy object strike sth e underbody or
ch assis components
In situations such as this, the body, the
underbody, chassis components, wheels or
tyres could be damaged without the damage
being visible. Components damaged in this wa
y can unexpec tedly fail or, in the case of
an accident, may not absorb the loads that
arise as intended.
If th e underbody panelling is damaged, flam‐
mable materials such as lea ves, grass or
twigs can collect between the underbody and
th e underbody panelling. These materials
may ignite if they come into contact wi thhot
parts on theex haust sy stem. #
Have theve hicle checked and repaired
immediately at a qualified specialist
wo rkshop.
or #
If driving saf ety is impaired while con‐
tinuing your journe y,pull over and stop
th eve hicle immediately in accordance
with the traf fic conditions, and contact
a qu alified specialist workshop. Declaration of Conformity

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 (/ page 260).
The sensors must not be co vered, forex ample
by cycle rack s, overhanging loads, sticke rs,fo il
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 driver assis tance sy stem may
no longer workproperly. Overview of driving sy

R During braking, e.g. at full brake application
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. 13 6

Lane Keeping Assist can neither reduce therisk
of an accident if youfa ilto adapt your driving
st yle nor override the la wsof ph ysics. It cannot
ta ke into account road, weather or traf fic condi‐
tions. Lane Keeping Assist is only an aid. You are
re sponsible for maintaining a safe dis tance to
th eve hicle in front, forve hicle speed, for braking
in good time and forst ay ing in lane.
Lane Keeping Assist is available in the speed
ra nge between 60 km/h and 200 km/h.
Sy stem limitations
The sy stem may be impaired or may not function
in thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, if there are
highly variable shade conditions or in rain,
sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming traf fic,
th e sun or reflections. R
Ifth e windscreen in the area of the multi‐
function camera is dirty, or if the camera is
mis ted up, damaged or co vered.
R Ifth ere are no lane markings, or se veral
unclear lane markings are present for one
lane, e.g. around roadwor ks.
R Ifth e lane markings are worn, dark or cov‐
ered.
R Ifth e dis tance totheve hicle in front is too
short and thus the lane markings cann otbe
de tected.
R Ifth e lane markings change quickl y,e.g.

vethefo llowing information: Cleaning
Avoiding dama getothe decorative foil
R For cleaning, use plenty of water and a mild cleaning agent without
additives or abrasive substances, e.g. a car sha mpoo appr ovedfor
Mercedes-Benz.
R Remo vedirt immediately, where possible, whilst avoiding rubbing
to o hard. There is otherwise a risk of damaging the decorative foil
ir re parably.
R Ifth ere is dirt on thefinish or if the decorative foil is dull: use the
Pa int Cleaner recommended and appr ovedfo r Mercedes-Benz.
R Insect remains: soak with insect remo ver and rinse off the treated
areas af terw ards.
R Bird droppings: soak with water and rinse off af terw ards.
R Toprev ent waterst ains, dry a foil-wrapped vehicle with a soft,
absorbent clo thafte reve rycar wash. R
The service life and colouring of decorative foils are impaired by:
- sunlight
- temp erature, e.g. hot air blo wer
- weather conditions
- stone chippings and dirt
- chemical cleaning agents
- oily products
R Do not use polish on matt decorative foil. Po lishing will ha vethe ef fect of
shining thefo il-wrapped sur face.
R Do not treat matt or stru ctured deco rative foils with wax.Pe rm anent
st ains may occur. Sc
ratches, cor rosive deposits, areas af fected by
cor rosion and damage caused byincor rect care
cannot al ways be comple tely repaired. In such
cases, visit a qualified specialist workshop.
Yo u can obtain more information on care and
cleaning products from the manufacturer. In
the case of foil-wrapped sur faces, optical dif‐
fe re nces may occur between the sur faces that
