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, e.g. due tomaximum full-s top
braking or insuf ficient traction of the tires.
RVe hicle 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‐

Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traf fic situa‐

In addition, thesteering support of Evasive
St eering Assist is general lynot suff icientto
avo id a collision.
In such cases Evasive Steering Assist can:
Rgive an unnecessary warning or pr ovide

Rnot give awa rning or not pr ovide assis‐
ta nce
#Alw ays pay careful attention tothe traf‐
fi c situation; do not rely on Ev asive
St eering Assist alone.
#Be ready tobrake and take evasive
action if necessar y.
#Preve ntthe assis tance byactively steer‐
ing in non-critical driving situations.
#Drive at an appropriate speed if pedes‐
trians are close tothe path of your vehi‐
cle.
Also obser vethe sy stem limitations of Evasive
St eering Assist.
Sy stem limitations
Ac tive Brake Assi stmay be impai red or may not

RIf a loss of tire pressure or a defective tire
has been de tected and displ ayed.
The sy stem may not react cor rectly:
RIn complex traffic st ations where objects
cannot alw ays be clearly identified.
RTo pedestrians or vehicles if they mo ve
