Function of the radar sensors
Some driving and driving safety systems use
radar sensors to monitor the area in front of,
behind or next to the vehicle (depending on the
vehicle's equipment).
Depending on the vehicle's equipment, the radar
sensors are integrated behind the bumpers
and/or behind the radiator grill or the Mercedes
star. Keep these parts free of dirt, ice and slush
( page 364). The sensors must not be covered,
→
for example by bicycle racks, overhanging loads
or radar-reflecting stickers. Following an impact
and in the event of associated damage, which
may not be visible, to the bumpers or radiator
grill, have the function of the radar sensors
checked at a qualified specialist workshop. The
driver assistance system may no longer work
properly.

Function of ABS (Anti-lock Braking System)
ABS regulates the brake pressure in critical driv‐
ing situations:
During braking, e.g. at full brake application
R
or insufficient tire traction, the wheels are
prevented from locking.
Vehicle steerability while braking is ensured.

If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
