wi th hot parts of theex haust sy stem.
#When driving on unpa vedro ads or off-

TEDama getotheve hicle
In thefo llowing situations, in particular, there
is a risk of damage totheve hicle:
RThe vehicle becomes grounded, e.g. on a
high curb or an unpa vedro ad.
RThe vehicle is driven toofast over an
obs tacle, e.g. a curb, speed bump or pot‐
hole.
RA heavy object strike sth e underbody or
ch assis components.
In situations such as this, the body, the
underbody, chassis components, wheels or
tires could be damaged without the damage
being visible. Components damaged in this
wa ycan unexpec tedly fail or, in the case of
an accident, may not absorb the loads that
arise as intended.
If th e underbody paneling is damaged, flam‐
mable materials such as lea ves, grass or
twigs can collect between the underbody and
th e underbody paneling. These materials may
ignite if they come into contact wi thhot
parts on theex haust sy stem.
#Ha ve theve hicle checked and repaired
immediately at a qualified specialist
wo rkshop.

Child restra int sy stems on the front
passenger seat
Note s onchild restra int sy stems on the front
passenger seat
Ac cident statistics show that children secured in
th ere ar seats are safer than children secured in
th e front seats. Forth is reason, Mercedes-Benz
stro ngly advises that you ins tall a child restra int
sy stem on a rear seat.
If it is absolutely necessary toins tall a child
re stra int sy stem on the front passenger seat,
alw ays obser vethe information on the automatic
front passenger front airbag shutoff
(
→page 43).
By doing this, you can avoidrisks caused by:
RAch ild restra int sy stem that is not de tected
by the automatic front passenger front airbag
shutoff.
RThe unintentionally deactivated front
passenger airbag.
RIncor rect positioning of thech ild restra int
sy stem.
Note s onforw ard-facing and rear wa rd-facing
ch ild restra int sy stems on the front
passenger seat
When using a rear wa rd-facing child restra int sys‐
te m on the front passenger seat, the front
passenger front airbag must alw ays be deactiva‐
te d. This is only the case if thePA SSENGER AIR
BA G OFF indicator lamp is lit continuously
(
→page 45).
When using thech ild restra int sy stem on the
front passenger seat, it is essential toobser ve
th efo llo wing:
RMo
vethe front-passen ger seat as far back as
possible and also into the highest position.
RSet the seat backrest toan almost vertical
position.
RRe tract the seat cushion length as far as pos‐
sible.

Driving and driving saf ety sy stems
Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist youin drivin g, parking and maneu‐
ve ring theve hicle. The driving sy stems are tools
and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times and inter
vene when necessary . Beaware of the
limitations rega rding the safe use of these sys‐
te ms.
Fu nction of thera dar senso rs
Some driving and driving safe ty systems 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 (
→page 336).
The sensors must not be co vered, forex ample
by bicycle rack s, ove rhanging loads or radar-
re flecting sticke rs.Fo llowing an impact and in
th eeve nt of associated damage , which may not
be visible, tothe bumpers or radiator grille, ha ve
th e function of thera dar sensors checked at a
qu alified specialist workshop. The driver assis‐
ta nce sy stem may no longer workproperly.

Fu nctions of ABS (Anti-lock Brake Sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
RVehicle steerability while braking is ensured.
If ABS inter venes when braking, youwill 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.
Sy stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a
malfunction has occur red and theye l‐
low ! ABSwarning lamp lights up contin‐
uously in the instrument clus ter af terth e

Fu nction of BAS (Brake Assist Sy stem)
&
WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
te m)
If BA S is malfunctioning, the braking dis tance
in an eme rgency braking situation is
increased.
#Depress the brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.
BA S suppo rts yo ur eme rgency braking situation
with additional brake forc e.
If yo u depress the brake pedal quickl y,BA S is
acti vated:
RBA S au tomatical lyboosts the brake pres‐
sure.
RBA S can short enthe braking dis tance.
RABS pr events the wheels from locking.
The brakes will function as usual once you
re lease the brake pedal. BAS is deactivated.
Functions of ESP®(Electronic Stability Pro‐
gr am)
&
WARNING Risk of skidding if ESP®is
malfunctioning
If ESP
®is malfunctioning, ESP®cannot car ry
out vehicle stabilization. In addition, other
driving saf etysy stems are switched off.

dirty, fogged up, damaged or co vered.
RAbsence of lane markings, or se veral unclear
lane markings, or if the markings change rap‐
idl y.
RThe dis tance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
RThe car riag ewa yis nar rowand winding.
RObstacles on the lane or projecting out into
th e lane.
The sy stem does not pr ovide assis tance in the
