Data stored in the vehicle
Data storage
Aw
ide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
Rvehicle's operating state
Rincidents
Rmalfunctions
In general, this technical information docu-
mentst he state of acomponent, amodule, a
system or the surroundings.
These include, for example:
Roperating conditions of system components,
e.g. fluid levels
Rthe 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
Rmalfunction sand defects in important system
components, e.g. lights, brakes
Rvehicle reactionsa nd operating conditions in
special driving situations, e.g. air bag deploy-
ment,i ntervention of stability control sys-
tems
Rambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
Rassist in recognizing and rectifying malfunc-
tions and defects
Ranalyze vehicle functions, e.g. after an acci-
dent
Roptimize vehicle function
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 malfunction data memory.

Introduction

Limited braking performance on salt-
treated roads
If you driveonsalted roads,alayer of salt resi-
due may for monthebraked iscsand brake
pads. This can result in asignificantly longer
braking distance.
RIn ordertop revent any salt build-up, apply the
brakes occasionally while paying attention to th et raffic conditions.
RCarefully depress th ebrakep edal and the
beginnin gand end of ajou rney.
RMaintain agreater distanc etothevehicle

Observe additional warning messages in the
multifunction display.
The brakef luid level may be to olow due to
brak epad wear or leaking brak elines.
Hav ethe brakes ystem checked immediately.
Consult aqualifie dspecialist workshop to
arrange this.
!As th eESP®system operates automatically,
th ee ngine and th eignitio nmust be switched
off (th eSmartKey must be in position uor
1 in th eignitio nlock), if th eelectric parking
brakeist ested onabraking dynamometer
(maximum 10 seconds).
Brakin gtriggered automatically by ESP
®may
cause severe damage to th ebrakes ystem.
All check sand maintenanc ework on th ebrake
system must be carried out at aqualifie dspe-
cialis tworkshop.
Hav ebrakep ads installe dand brak efluid
replaced at aqualifie dspecialist workshop.
If th ebrakes ystem has onl ybeen subject to
moderatel oads, you should tes tthe functional-
ity of your brakes at regular intervals.

High-performance brake system
(except Mercedes-AMG SLC 43)
AM Gb rakes ystems are designed for heavy
loads and have component swith corresponding
properties. This may lead to noise when braking.
This will dependo n:
RSpeed
RBrakingforce
RAmbientc onditions, e.g .temperature and
humidity
The wear of individual component softhebrake
system, such as th ebrakep ads/linings or brake
discs, depends on th eindividual driving style
and operatin gconditions.
For this reason, it is impossibletos tate am ile-
age that will be valid unde rall circumstances. An
aggressived riving style will lead to high wear.
You can obtain morei nformationonthisf roma
qualifie dspecialist workshop.
New and replaced brakep ads and discsonly
reacht heir optimum braking effect after several
hundred kilometers of driving .Compensate for
this by applyingg reater force to thebrakep edal.
Keep this in mind, and adapt your driving and
braking accordingl yduringt hisb reak-in period.
Excessive heavy braking results in correspond-
ingly high brak ewear. Observe th ebrakes ystem
warning lamp in th einstrumentc luster and note
any brak estatus messages in th emultifunction
display. Especially for high performanc edriving,
it is important to maintain and have th ebrake
system checked regularly.

$JN$ (USA only) or J(Canada only): the red brake system warning lamp is
lit while the engine is running. Awarning tone also sounds.
GWARNING
There is not enough brake fluid in the brake fluid reservoir.
The braking effect may be impaired.
There is arisk of an accident.
XPull over and stop the vehicle safely as soon as possible, paying attention to road
and traffic conditions. Do not continue driving under any circumstances.
XSecure the vehicle against rolling away (Ypage 131).
XDo not add brake fluid. Adding more will not correct the malfunction.
XConsult aqualified specialist workshop.
XObserve the additional display messages in the multifunction display.
$NUSA only: the red brake system warning lamp is lit while the engine is running.
The multifunction display also shows adisplay message with the #symbol.
The brake pads/linings have reached their wear limit.
XVisit aqualified specialist workshop.
!NThe yellow ABS warning lamp is lit while the engine is running.
ABS (anti-lock braking system) is malfunctioning.
If there is an additional warning tone, the EBD (electronic brake force distribution)
is malfunctioning.
Other driving systems and driving safety systems may also malfunction.
GWARNING
The brake system continues to function normally, but without the functions listed
above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance in an emergency braking situation can increase.
If ESP
®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XObserve the additional display messages in the multifunction display.
XDrive on carefully.
XVisit aqualified specialist workshop immediately.
If the ABS control unit is faulty, there is also apossibility that other systems, such
as the navigation system or the automatic transmission, will not be available.
