PASSENGER AI RBAG indicator lamp
PASSENGER AIR BAG ON indicator lamp :and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS). The indicator lamps display the statu
softhe
front-passenger front ai rbag.
RPASSENGER AIR BAG ON lights up for 60 sec-
onds ,sub sequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF):t he
front-passenger front ai rbag is able to deploy
in the event of an accident.
RPASSENGER AIR BAG OFF lights up :the front-
passenger front ai rbag is deactivated. It will
then not be deploye dinthe event of an acci-
dent.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the statu softhe front-passenger
front ai rbag.T he PASSENGER AIR BAG OFF
indicator lamp may be li tcontinuously or be off.
Depending on the person in the front-passenger
seat, the front-passenger front ai rbag must
either be deactivated or enabled; see the fol-
lowing points. Yo umustm ake sure of this both
before and during ajourney.
RChildreninac hild restraintsystem:
whethert he front-passenger front ai rbag is
enabled or deactivated depends on the instal- le dc hild restraint system, and the ag eand
size of the child .Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 47 )and on "Chil-
dre nint he vehicle" (Ypage 54). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAl lo the rpersons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front ai rbag is ena-
bled or deactivated (
Ypage 47). Be sure to
observe the notes on "Seat
belts“ (
Ypage 41 )and "Ai rbags"
(Ypage 45). There yo ucan also find infor-
mation on the correct seatp osition.

Important safet ynotes
If you fail to adapt your drivin gstyle or if you are
inattentive ,the drivin gsafet ysystems can nei-
ther reduce th eriskofana ccidentnor override
th el aws of physics. Driving safet ysystems are
merely aids designed to assist driving. You are
responsible fo rmaintainin gthe distanc etothe

goo dtime, and fo rstayin ginl ane. Always adapt
your drivin gstyle to suit th eprevailin groada nd

from th evehicle in front. Drive carefully.
The drivin gsafet ysystems described only wor k
as effectively as possible when there is ade-
quat econtac tbetween th etires and th eroad
surface. Please pay special attention to th e
note sont ires ,recommended minimum tire
tread depths, etc. (
Ypage 288).
In wintr ydrivin gconditi ons, always use winte r
tires (M+ Stires )a nd if necessary,s now chains.
Onlyint hiswaywill the driving safety systems
describe dinthissection work as effectively as
possible.
ABS (Anti-lock Brakin gSystem)
General information
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking. The
! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goe soutwhen the engine is running.
ABS works from aspeed of about5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, eve nwheny ou
onlyb rake gently.
Important safety notes
iObserve the "Important safety notes "sec-
tio n(Ypage 61).
GWARNING
If ABS is faulty ,the wheels could lock when
braking .The steerability and braking charac-
teristic smaybe severely impaired.A ddition-
ally ,further driving safety systemsa re deac-
tivated.T here is an increased danger of skid-
ding and accidents.
Driv eonc arefully. Hav eABS checked imme-
diately at aquali fied specialist workshop.
Whe nABS is malfunctioning ,othe rsystems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (
Ypage 220 )and dis-
play messages which maybes hown in the
instrument cluster (
Ypage 192).
Braking
XIf ABS intervenes: continue to depress the
brake peda lvigorously unti lthe braking sit-
uatio niso ver.
XTo make afullb rake application: depress
the brake peda lwithf ullf orce.
If ABS intervene swhenb raking ,you will fee la
pulsing in the brake pedal.
The pulsating brake peda lcan be an indication
of hazardousr oadconditions, and functions as a
reminder to take extra car ewhile driving.
BAS (Brak eAssis tSystem)
General information
BAS operates in emergency braking situations.
If yo udepress the brake peda lquickly, BAS
automaticall yboosts the braking force,t hus
shortening the stopping distance.

GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully.H ave ESP
®checked at a
qualified specialist workshop.
Vehicles without 4MATIC: when towing your
vehiclew ith the front axle raised, it is important
that you observe the notes on ESP
®
(Ypage2 82).
If the å ESP®OFF warning lamp lights up
continuously,E SP®is deactivated.
If the ÷ ESP®warning lamp and the å
warning lamp are lit continuously,E SP®is not
available due to amalfunction.
Observe the information on warning lamps
(
Ypage2 21) and display messages which may
be shownint he instrument cluster
(
Ypage1 92).
Only use wheels with the recommendedt ire
sizes. Only then wil lESP
®function properly.
Characteristics of ESP®
General information
If the ÷ ESP®warning lamp goes out before
beginning the journey ,ESP®is automatically
active.
If ESP
®intervenes, the ÷ESP®warning lamp
flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedalasf ar as
necessary when pulling away.
XAdapt you rdriving style to sui tthe prevailing
road and weather conditions.
ECOs tart/stop function
The ECO start/stop function switches the
engine off automatically when the vehicles tops
moving. The engine starts automatically when
the driverw ants to pullawa ya gain. ESP
®
remains in its previousl yselected status. Exam-
ple: if ESP®was deactivated before the engine
was switched off, ESP®remains deactivated
when the engine is switched on again.
Deactivating/activating ESP®(except
Mercedes‑AMG vehicles)
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage6 1).
You can select between the following states of
ESP
®:
RESP®is activated.
RESP®is deactivated.
GWARNING
If you deactivate ESP
®,E SP®no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP
®in the situations descri-
bed in the following.
The spinning of the wheels results in acutting
action for better traction on looses urfaces.
It may be best to deactivate ESP
®in the follow-
ing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
iActivate ESP®as soon as the situations
described above no longer apply.E SP®will
otherwise not be abl etostabilize the vehiclei f
the vehicles tarts to skid or awhee lstarts to
spin.
!Avoid spinning the drivenw heels for an
extended period with ESP®deactivated. You
coul dotherwise damage the drivetrain.
Deactivating/activating ESP®
You can deactivate or activate ESP®via the on-
board computer (Ypag e185).
ESP®deactivated:
The å ESP®OFF warning lamp in the instru-
ment cluster lights up.
ESP
®activated:
