R During braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tyres,
th e wheels are pr evented from blocking.
R Vehicle steerability while braking is ensured.
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

indicates visually and audibly the dis tance
between your vehicle and an object.
Pa rking Assist PARKTRONIC is on lyan aid. It is
not a substitute foryo ur attention tothe sur‐

parking in/exiting parking spaces.
In thest andard setting, an intermit tent wa rning

0.3 m toan obs tacle. A continuous tone sounds
from a di stance of appr oximately 0.2 m. You can
set thewa rning tone in the multimedia sy stem
so that it will sound earlier at a greater dis tance
of appr oximately 1.0 m (→ page197).
