Vehicles with Blind Spot Assist: Cross Traffic
Alert can warn drivers of any crossing traffic
when backing up out of a parking space. The
radar sensors in the bumper also monitor the
area adjacent to the vehicle. If a critical situation
is detected, symbol 1 appears in the media dis‐
play. If the driver does not respond to the warn‐
ing, the vehicle's brakes can be applied automat‐
ically.
If the radar sensors are obstructed by vehicles
or other objects, detection is not possible.
Cross Traffic Alert is active under the following
conditions:

ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto‐
nous journeys, e.g. on highways and trunk roads.
If ATTENTION ASSIST detects indicators of fati‐
gue or increasing lapses in concentration on the
part of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration
in time. The system is not a substitute for a well-
rested and attentive driver. On long journeys,
take regular breaks in good time that allow for
adequate recuperation.
You can choose between two settings:
Standard: normal system sensitivity.
R
Sensitive: higher system sensitivity. The
R
driver is warned earlier and the attention
level detected by ATTENTION ASSIST is adap‐
ted accordingly.
If drowsiness or increasing lapses in concentra‐
tion are detected, the ATTENTION ASSIST: Take
a Break! warning appears in the Instrument Dis‐
play. You can acknowledge the message and
