Ingeneral, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
Roperating statuses of sy stem components
(e.g. fluid leve ls, battery status, tire pressure)
Rstatus messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, decele ration, lat‐
eral acceleration, display of thefast ened seat
belts)
Rmalfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
Rinformation on vehicle damage events
Rsystem reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
Rambient conditions (e.g. temp erature, rain
sensor)
In addition toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this
data is temp orary and is only processed in the ve
hicle itself. Only a small portion of the data is
st ored in theev ent or malfunction memor y.
When service workis done on your vehicle, the
te ch nical da tafrom theve hicle can be read out
by service network staff (e.g. workshops, manu‐
fa cturer) or third parties (e.g. breakdown serv‐
ices). Services include repair services, mainte‐
nance processes, warranty events a
nd
quality
assurance measures, forex ample. The read out
is per form ed via the legally prescribed port for
th e diagnostics connection in theve hicle. The
re spective service network locations or third
parties collect, process and use the data. They
document tech nical statuses of theve hicle,
assist in finding malfunctions and impr oving
qu ality and are transmitted tothe manufacturer,
if necessar y.Fu rthermore, the manufacturer is
subject toproduct liability. Forth is, the manu‐
fa cturer requirestech nical da tafrom vehicles.
Malfunction memories in theve hicle can be
re set bya service outlet as part of repair or
maintenance work.
They can enter data into theve hicle's comfort
and inf otainment functions themselves as part
of the selected equipment. These include:
Rmultimedia data such as music,
films or pho‐
to sfo r playba ckin an integrated multimedia
sy stem
Raddress book data for use in connection with
an integrated hands-free sy stem or an inte‐
grated navigation sy stem
Rentered navigation destinations
Rdata about the use of Internet services
This data can be sa ved locally in theve hicle or it
is located on a device which you ha veconnected
to theve hicle (e.g. smartphone, USB flash drive
or MP3 pla yer). If this data is stored in theve hi‐
cle, you c
an dele
teit at any time. This data can
only be transmitte dto third parties upon your
re qu est with particular rega rd tothe scope of
use of online services according toyour selected
settings.
Yo u can store or change con venience settings/
individualization in theve hicle at any time.

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.
BA S suppo rts yo ur eme rgency braking situation
with additional brake forc e.
If yo u depress the 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.

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.
Cruise contro l is operated using the cor respond‐
ing steering wheel buttons. You can store any
ro ad speed abo ve15 mp h (20 km/h) up tothe
maximum speed.
If yo ufa ilto adapt your driving style, 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 lane. Displa

The status of cruise control and thestored
speed are shown in the multifunction displa y.

% The segments between thestored speed and
th e end of the segment display light up in

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.

Driving and pa rking

Changeinto a lowerge 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.
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.
RIfyo u are driving when vis ibilityis poor.

If yo u call up thestored speed and this is
lo we rth an your cur rent speed, theve hicle
decelerates.
#Ta ke into account the tra ffic situation
before calling up thestored speed.
Re quirements:RESP®must be activated, but not inter vening.

Ac tive Di stance Assist DI STRONIC
Function of Active Di stance Assist
DI STRO NIC
Active Dis tance Assist DISTRONIC maintains the
set speed on free-flowing roads. If vehicles
ahead are de tected, the set dis tance is main‐
ta ined, if necessar y,until theve hicle comes toa
halt. The vehicle accelerates or brakes depend‐
ing on the dis tance totheve hicle in front and
th e set speed. Speed (in thera nge between
15 mp h(2 0 km/h) and 130mp h(210 km/h))
and the dis tance totheve hicle ahead are set
and sa ved on thesteering wheel. Other
features of Active Dis tance Assist
DISTRONIC:
RAd justs the driving style depending on the
selected drive program (fuel-saving, comfort‐
able or dynamic) (
→page 136)
RRe acts tostationary vehicles in urban speed
ra nges (e xcept bicycles and mo torcyc les) if
conditions are suf ficient toenable de tection.
It also does not de tect pedestrians.
RInitiates rapid acceleration tothestored
speed, if the turn signal indicator is switched
on tochange totheove rtaking lane.
RTa ke s one-sided overtaking restrictions into
account on highw ays or on multi-lane roads
with separate roadw ays.
Ve hicles with Active Parking Assis t:ifth eve hicle
has been braked toast andstill on a multi-lane,
separate roadw ay by Active Dis tance Assist
DISTRONIC, it can au tomatical lyfollow th
eve hi‐
cle in front driving off again within 30 seconds. If
a crit

ical situation is de tected when driving off, a
visual and acoustic warning is given indicating
th at the driver must now take control of theve hi‐
cle. The vehicle is not accelerated any fur ther.

RIfAc tive Dis tance Assist DISTRONIC no
longer de tects a vehicle in front or does
not react toreleva nt objects.
#Alw ays carefully obser vethe traf fic con‐
ditions and be ready tobrake at all
times.
#Ta ke into account the tra ffic situation
before calling up thestored speed.
&
WARNING Risk of accident due toinsuf‐
fi cient decele ration byActive Dis tance
