Flammable material such as lea ves, grass or
twigs may ignite if they come into contact
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.
or
#If driving saf etyis 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.

Childrestra 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.
RThe entire base of thech ild restra int sy stem
must alw aysre st on the seat cushion of the
front-passenger seat.

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.

If yo udepr essthe 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.
#Drive on carefull y.
#Have ESP®checked at a qualified spe‐
cialist workshop.
&
WARNING Risk of skidding if ESP®is
deactivated
If yo u deactivate ESP
®, ESP®cannot car ry
out vehicle stabilization.
#ESP®should only be deactivated in the
fo llowing situations.
Mercedes‑AMG vehicles: observeth e no tes in
th e Supplement. Otherwise, you may failto rec‐
ognize dangers.
ESP
®can monito r and improvedriving stability
and traction in thefo llowing situations, within
ph ysical limits:
RWhen pulling away on wet or slippe ryroads.
RWhen braking.
RIn stro ng side winds when you are driving
fast erthan 50 mph (80 km/h). If
th eve hicle deviates from the direction desired
by the driver, ESP
®can stabilize theve hicle by
inter vening in thefo llowing ways:
ROne or more wheels are braked.
RThe engine output is adap ted according to
th e situation.
ESP

ing lamp lights up continuously in the instrument
clus ter:
RDriving stability will no longe r be improved.
RCrosswind Assist is no longer active.
RThe drive wheels could spin.
RETS/4ETS traction control is still active.
% When ESP
®is deactivated, you are still assis‐
te dby ESP®when braking.
ESP
®is inter vening if the÷ ESP®warning
lamp flashes in the instrument clus ter:
RDo not deacti vate ESP®.
ROnly depress the accelera tor pedal as far as
is necessar y.

Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 396).
& WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid constantly absorbs moisture
from the air. This lo wersthe boiling point of
th e brake fluid. Ifth e boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired.
#Ha ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0.
