This function is not available in all countries.
The ROAD SURFACE SCAN function monitors the
road in front of your vehicle using a multifunc‐

unevenness in the road surface, e.g. bumps,
before the vehicle drives over them. Chassis
movements are reduced and driving comfort is
increased.
ROAD SURFACE SCAN is automatically activated
if the following conditions are met:
Drive program A (Comfort) or N
R
(CURVE) is selected.
