These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
mentst he state of acomponent, amodule, a
system or the surroundings.
These include, for example:
R operating conditions of system components,
e.g. fluid levels
R the vehicle's status messages and those of its
individual components,e .g. number of wheel
revolutions/speed, deceleration in move-
ment,l ateral acceleration ,accelerator pedal
position
R malfunctions and defect sinimportant system
components,e .g. lights, brakes
R vehicle reaction sand operating conditions in
special driving situations, e.g. airbag deploy-
ment,i ntervention of stability control sys-
tems
R ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory
and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
The vehicle is read out by employees of the ser- vice network (including the manufacturer) using
special diagnostic testers. You can obtain more information there, if required.
After afault has been rectified, the information
is deleted from the fault memory or is continu-
ally overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec- tion with other information (if necessary, after
consultation with an authorised expert), could
be traced to aperson.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for example, vehicle location in case of an emer-
gency. Copyright information

The restraint systems functions are checked
after the ignition is switched on and at regular
intervals when the engine is running. This allows
malfunctions to be quickly identified.
The 6 restraint system warning lamp in the
instrumentc luster lights up when the ignition is
switched on. It goes out no later than afew sec-
onds after the vehicle is started. The compo-
nentsoft he restraint system are in operational
readiness.
Am alfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not switch off after afew seconds when
the engine is running
R lights up again when the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensionersora irbags, for example.
There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at aqualified specialist
workshop. PASSENGER AIR BAG indicator lamp PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up: the front-
passenger front airbag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front airbag is
deployed.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
Depending on the person in the front-passenger seat, the front-passenger front airbag must
either be disabledore nabled; see the following
points. You must make sure of this both before
and during ajourney.
R Children in arearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 47) and on "Children in the
vehicle" (Y page 55).
R Children in aforward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabledore nabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva-
tion system" (Y page 47) and on "Children in
the vehicle" (Y page 55).
R All other persons: the PASSENGER AIR BAG
ON indicator lamp must be lit. The front-
passenger front airbag is enabled. Depending on the build of the person on the front-
passenger seat, the PASSENGER AIR BAG
OFF indicator lamp may light up. The front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident. In
this case, the front-passenger seat should not be used.
It is imperative to observe the notes on the
"Automatic front-passenger front airbag
deactivation system" (Y page 47) as well as
on "Seat belts" (Y page 41) and "Airbags"
(Y page 44). There you can also find infor-
mation on the correct seat position. 40

Operation of automatic front-passenger
front airba gdeactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps show you whether the co-
driver's fron tairbag is disabled or enabled.
X Press the Start/Stop button onceort wice or
turn the key to position 1or 2in the ignition
lock.
The system carries out aself-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps then show the status of the
co-driver's fron tairbag.
R PASSENGER AIR BAG ON is lit: the co-driver's
fron tairbag is enabled. If, in the case of an
accident, all deployment criteria are met, the
co-driver's fron tairbag is deployed.
R PASSENGER AIR BAG OFF is lit: the co-driv-
er's fron tairbag is disabled. It will then not be
deployed in the event of an accident.
If the status of the co-driver's fron tairbag
changes while the vehicle is in motion ,anairbag
display message appears in the instrument clus-
ter (Y page 263). When the co-driver's seat is
occupied, alway spay attention to the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps. Be aware of the status of the co-driver's fron tairbag both before and
during the journey.
If ap erson is occupying the co-driver's seat,
they must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet restin gonthe floor, if possible If the co-driver does not observe this, the auto-
matic co-driver's fron tairbag deactivation sys-
tem may be influenced, for example if the co-
driver:
R transfers their weight by supportin gthem-
selves on avehicle armrest
R sits in such away that their weight is raised
from the seat cushion
This or similar behaviour can cause the co-driv-
er's fron tairbag to be deactivated when it
should not be. In this case, PASSENGER AIR BAG OFF indicator lamp lights up continuously. The
co-driver's fron tairbag is then not deployed in
an accident. G
WARNING
If the PASSENGER AIRBA GOFF indicator lamp
is lit, the front-passenger fron tairbag is disa-
bled. It will not be deployed in the event of an
acciden tand cannot perform its intended pro-
tective function .Aperson in the front-
passenger seat could then ,for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injur yore ven fatal injury.
When the front-passenger seat is occupied,
alway smake sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger fron tairbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
fron tairbag is correct. G
WARNING
If you secure achild on the co-driver's seat in
ar earward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struc kbythe airbag. There is an
increased risk of injury, possibly even fatal. 48
Occupant safetySafety
Page 52 of 385

In this case, always ensure that the co-driver's
airbag is disabled.T he PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator light is lit, do not fit arearward-
facing child restraint system on the co-driver's
seat. Further information can be obtained under
"Problems with the automatic co-driver's front
airbag deactivation system" (Y page 52).G
WARNING
If you secure achild in aforward-facing child
restraint system on the front-passenger seat
and you positio nthe front-passenger seat too
close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG ON indicator lamp is lit
This poses an increased risk of injury or even fatal injury.
Alwaysm ove the front-passenger seat as far
back as possible and fullyr etract the seat
cushio nlength. Alwaysm ake sure that the
shoulder belt strap is correctly routed from
the vehicle belt outlet to the shoulder belt
guideont he child restraint system. The shoul-
der belt strap must be routed forward sand
downwards from the vehicle belt outlet. If
necessary ,adjust the vehicle belt outlet and
the front-passenger seat accordingly .Always
observe the information abouts uitable posi-
tioning of the child restraint system in this
Owner's Manualasw ell as the child restraint
system manufacturer's installation instruc-
tions.
If the automatic co-driver's front airbag deacti-
vation system detects that:
R the co-driver's seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and remains lit. This indicates that the co-driver's
front airbag is disabled.
R the co-driver's seat is occupie dbyachild in a
rearward-facing child restraint system, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the co-driver's front airbag is disabled.
But in the case of achild in arearward-facing
child restraint system, the PASSENGER AIR
BAG ON indicator lamp can be lit continuously
after the system self-test. This indicates that
the co-driver's front airbag is enabled. The
resultoft he classification is dependent on,
among other factors, the child restraint sys-
tem and the child's stature. It is recommen-
ded that you fit the child restraint system to a
suitable rear seat.
R the co-driver's seat is occupie dbyachild in a
forward-facing child restraint system, either
the PASSENGER AIR BAG ON or PASSENGER
AIR BAG OFF indicator lamp lights up after the
system self-test depending on the resultof
the classification and remains lit. The resultof the classification is dependent on, among
other factors, the child restraint system and
the child's stature.
Move the co-driver's seat as far back as pos-
sible. Alwayso bserve the information on
"Child restraint systems on the co-driver's
seat" (Y page 59) and on "Suitable posi-
tioning of the child restraint system"
(Y page 60). Alternatively ,fit the child
restraint system on asuitable rear seat.
R the co-driver's seat is occupie dbyaperson of
smaller stature (e.g. ateenager or small
adult), either the PASSENGER AIR BAG ON or the PASSENGER AIR BAG OFF indicator lamp
lights up and remains lit after the system self- test depending on the resultoft he classifica-
tion.
- If the PASSENGER AIR BAG ON indicator
lamp is lit, move the co-driver's seat as far
back as possible. Alternatively ,aperson of
smaller stature can sit on arear seat.
- If the PASSENGER AIR BAG OFF indicator
lamp is lit, aperson of smaller stature
shouldn ot use the co-driver's seat.
R the co-driver's seat is occupie dbyanadult or
ap erson of astature corresponding to that of
an adult, the PASSENGER AIR BAG ON indi-
cator lamp is lit continuously after the system
self-test. This indicates that the co-driver's
front airbag is enabled. Occupant safety

General notes Accident statisticss
how that children secured
in the rear seats are safer than children secured
in the front seats. For this reason, Mercedes-
Benz strongly advises that you fit achild
restraint system on arear seat.
Vehicles with the automatic co-driver's front air-
bag deactivation system: if it is absolutely nec-
essary to fit achild restraint system to the co-
driver's seat, always observe the notes on the
"Automatic co-driver's front airbag deactivation system" (Y page 47). You can thus avoid the risks that could arise as
ar esult of:
R ac hild restraint system that is not detected
by the automatic co-driver's front airbag
deactivation system
R the unintentional disabling of the co-driver's
front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board. Please observe the warning notice on the co-
driver's sun visor, see the illustration. G
WARNING
If you secure achild on the co-driver's seat in
ar earward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The child could be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
NEVERu searearward-facing child restraint on a
seat protected by an ACTIVE AIRBAG in front of

cured in the vehicle, they may push abutton
or as witch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is arisk of an
accident and injury.
Never leave animals unattended in the vehi-

Brake (Y page 75)
R STEERC ONTROL (Y page 77) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front,f or vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather condition sand maintain asafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 353).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-loc
kBraking System)
General notes ABS regulates brake pressure in such
away that
the wheels do not lock when you brake. This
allowsy ou to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristic smay be severely impaired. Addition-
ally,f urther driving safety systems are deac- 66

WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus ,the distance warning function cannot
provid eawarning in all critical situations.
There is arisk of an accident.
Always pay carefu lattention to the traffic sit-
uation and be read ytobrake. G
WARNING
The distance warning function cannot always
clearly identify objects and comple xtraffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give awarning
There is arisk of an accident.
Always pay carefu lattention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues awarning
at speeds:
R of approximately 30 km/h or more, if, over
severa lseconds, the distance maintained to
the vehicl etravelling in front is insufficient.
The · distance warning lamp then lights
up in the instrument cluster.
R of approximately 7km/h or more, if you rap-
idlya pproach avehicl einf ront. An intermit-
tent warning tone willt hen sound,and the
· distance warning lamp willl ight up in the
instrument cluster.
X Brake immediatel yinorder to increas ethe
distance from the vehicl einfront.
or
X Take evasive action provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may alsoc ausethe system to display awarning. With the help of the rada
rsensor system, the
distance warning function can detect obstacles
that are in the path of yourv ehiclefor an exten-
ded period of time.
Up to aspee dofa pproximatel y70k m/h, the
distance warning function can alsor eact to sta-
tionary obstacles, such as stoppe dorparked
vehicles.
Autonomous braking function If the drive
rdoes not react to the distance warn-
ing signa linacritical situation, COLLISION PRE-
VENTION ASSIST PLUS can assist with the
autonomous braking function.
The autonomous braking function:
R gives the drive rmore time to react to critical
driving situations
R can help the drive rtoavoidana ccident or
R reduces the effects of an accident
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the
following spee dranges:
R 7-1 05 km/h for moving objects
R 7-50k m/h for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing spee dranges:
R 7-2 00 km/h for moving objects
R 7-50k m/h for stationary objects
Due to the nature of the system, complicated
but non-critical driving situations may also
caus ethe autonomous braking function to inter-
vene.
If the autonomous braking function demands
particularl yhigh braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page54).
Adaptive Brake Assist General notes
