Generall y,the use of these data is temp orar y;

th ete mp orary or permanent documentation of
te ch nical information about theve hicle's operat-

Depending on theve hicle equipment, thefo llo w-

R operating status of system components, such
as /ll le vels, tyre pressure or battery status
R malfunctions or faults in impor tant system

If yo u use services, such as repair services and

re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manu facturers or third parties, such as break-
down services. The same is true in the case of
wa rranty claims and quality assurance measures.
In general, there adout is per form ed via the legally
prescribed port forth e diagnostics connection in
th eve hicle. The operational data that are read out
document tech nical states of theve hicle or of
individual components and assist in the diagnosis
of malfunctions, compliance with warranty obli ga-
tions and quality impro vement. Tothat end, these
data, in particular information about component
loads, tech nical events, malfunctions and other
fa ults may be transmitted along with theve hicle
identi/cation number tothe manufacturer. Fur-
th ermore, the manufacturer is subject toproduct
liability. Forth is reason the manufacturer also uses operational data from
theve hicle, forex am-
ple, forre calls. These data can also be used to
ex amine the customer's warranty and guarantee
claims.
Fa ult memories in theve hicle can be reset by a

unctions of ABS
unctions of ABS The Anti-lock Brake System (ABS)
regulates the
brake pressure in critical driving situations:
R During braking, for instance, at maximum full-
stop braking or if there is insu1cient tyre trac-
tion, the wheels are pr evented from locking.
R Vehicle steerability while braking is ensu red.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road con-
ditions and can ser veas a reminder totake extra
care while driving.

Ac tive Steering Assist has a limited steering tor-
qu efo r lateral guidance. In some cases, the steer-
ing inter vention is not su1cient tokeep theve hi-
cle in the lane or todrive thro ugh exits.
The system may be impaired or may not function
in thefo llowing instances:
R There is poor visibility, e.g. due tosno w,rain,
fo g, heavy spr ay,gr eatly varying light condi-
tions or strong shadow s onthe car riag ewa y.
R There is glare, e.g. from oncoming tra1c,
di re ct sunlight or re0ections.
R Insu1cient road illumination.
R The windscreen is dirty, mis ted up, damaged
or co vered in the vicinity of the camera, e.g.
by a stic ker.
R No, or se veral, unclear lane markings are pres-
ent for one lane, or the markings change

junctions. R
The lane markings are wornawa y,dark or co v-
ered up, e.g. bydirt or sno w.
R Ifth e distance totheve hicle in front is too
short and thus the lane markings cannot be
de tected.
R The road is nar row and winding.
R There are obs tacles on the lane or projecting
out into the lane, such as object mar kers.
The system does not pr ovide assistance in thefo l-
lowing conditions:
R On tight bends and when turning.
R When crossing junctions.
R Atroundabouts or toll stations.
R When towing a trailer.
R When the tyre pressure is too lo w. &
