In addition to pr ov iding th e actual control unit
function, th is data assists th e manufacturer in
de te cting and re ctifying malfunctions and opti‐

st ored in th e ev ent or malfunction memor y.
When yo ur ve hicle is serviced, te ch nical da ta

wo rk emplo ye es or th ird parties. Services
include re pair services, maintenance processes, wa rr anty eve nts and qu ality assurance meas‐

th e legally prescribed port fo r OBD ("on-board

Fu rt hermore, th e manufacturer is subject to

Fu nctions of ABS (anti-lock braking sy st em)
ABS re gulates th e brake pressure in critical driv‐

th e wheels are pr ev ented from blocking.R
Ve hicle st eerability while braking is ensured.
If ABS inter ve nes when braking, yo u will fe el a
pulsing in th e brake pedal. The pulsating brake
pedal can be an indication of hazardous ro ad

Ac tive Brake Assi st can help yo u to minimize th e
ri sk of a collision with ve hicles or pedestrians or
to re duce th e ef fe cts of su ch a collision. If Ac tive Brake Assi st has de te cted a ri sk of colli‐

If yo u do not re act to th e visual or acoustic wa rn ‐
ing, autonomous braking can be initiated in criti‐

In especially critical situations, Ac tive Brake
Assi st can initia te autonomous braking direct ly .
In th is case, th e visual and acoustic wa rn ing
occurs simultaneously with th e braking applica‐
