The EDR inthis vehicle is designed torecord
such data as:
RHowvarious sy stems in your vehicle were
operating;
RWhe ther or not the driver and passenger
saf etybelt swe rebuckled/fas tened;
RHow far (if at all) the driver was depressing
th e accelerator and/or brake pedal; and,
RHow fasttheve hicle was tr ave ling.
This data can help pr ovide a better under stand‐
ing of the circums tances in which accidents and
inju ries occur. NOTE: EDR data is recorded by
yo ur vehicle only if a non-trivial crash situation
occurs; no data is recorded bythe EDR under
normal driving conditions and no personal data
(e.g. name, gende r,age and accident location) is
re corded. Ho wever,ot her parties, such as law
enforcement, could combine EDR data with the
type of pe rsonally identifying data routinely
acquired during a crash inve stigation.
Ac cess totheve hicle and/or the EDR is needed
to read data that is recorded bythe EDR, and
special equipment is requ ired. In addition tothe
ve hicle manufacturer, other parties that ha vethe special equipment, such as law enforcement,
can
read the information byaccessing theve hi‐
cle or the EDR.
EDR data may be used in civil and criminal mat‐
te rs as a tool in accident reconstruction, acci‐
dent claims and vehicle saf ety. Since
the Crash
D
ata Retrie val (CDR) tool that is used toextract
da ta from the EDR is commercially available,
Mercedes-Benz US A,LLC ("MBUSA") expressly
disclaims any and all liability arising from the
ex traction of this information byunauthorized
Mercedes-Benz personne l.
MBUSA willnot share EDR data withot hers with‐
out the consent of theve hicle owner or, if the

fe deral, state or local go vernment; in connection
with or arising out of litigation in volving MBU SA
or its subsidiaries and af filiates; or, as required
by law.
Wa rning: the EDR is a component of the
Re stra int Sy stem Module. Tamp ering with, alter‐
ing, modifying or removing the EDR component may
result in a malfunction of theRe stra int Sys‐
te m Module and other sy stems.
St ate la wsorregulations rega rding EDRs that
con flict with federal regulation are pre-em pted.
This means that in theeve nt of such conflict,the

Fu nctions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, the wheels are pr evented
from blocking, forex ample due tomaximum
full-s top braking or insuf ficient traction of the
tires.
RVe hicle steerability while braking is ensured.
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
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.

Speed control cruise control
Function of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
If yo ufa ilto adapt your drivin gst yle, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
ing in your lane.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out. Do not use cruise control in
thefo llowing situa‐
tions:RIn traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
ROn slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
RWhen visibility is poor.
Operating cruise control
& WARNING Risk of accident due to
unkno wnstored speed
If yo u call up thestored speed and this is
lo we rth an your cur rent speed, theve hicle
decelerates.
If yo udo not kn owthestored speed, the
ve hicle could decelerate unexpectedly.
#Take into account the tra ffic situation
before calling up thestored speed.
#If th estored speed is not known, store
th e desired speed again.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, youwill make use of the braking ef fect
of the engine. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
Re quirements
RCruise control is selected.
RESP®must be switched on, but not inter ven‐
ing.
RThe driving speed must be at least15mp h
(20 km/h).
