Intersection Assist
Intersection Assist monitors the areas around the
front and sides of the vehicle at intersections and
exits with the aid of the camera and radar sensors
installed in the vehicle and can warn the driver of
detected approaching cross traffic in complex inter-
section situations. Within the system limits, ap-
proaching, moving objects such as e.g. vehicles are
detected.
Switching Intersection Assist on
and off
Intersection Assist can be switched on and off in the
PCM.

e Intersection Assist
A switched-off system is switched on again the next
time the ignition is switched back on.
Operating principle
Intersection Assist is active under the following
conditions:
bb Intersection Assist is switched on.
bb PSM is switched on.
bb Speed is not higher than approx.
20 mph (30 km/h).
If a critical situation is detected by the Intersection
Assist, visual and acoustic warnings may be com-
municated to the driver via the instrument cluster,
the head-up display and the PCM, depending on the
vehicle speed and the time headway to the crossing
vehicle. Intersection Assist can trigger a warning jolt
via a braking intervention to warn the driver of a po-
tential collision.
Information display
In the event of a possible collision, a visual warning is
displayed on the instrument cluster and PCM.
– Red arrows indicate the direction from which the
cross traffic is approaching.
– The display in the PCM only appears when Par-
kAssist is activated.
– The display in the instrument cluster only ap-
pears when the ACC main menu is activated.
Warnings
Fig. 80: Collision warning on the instrument cluster
If the system detects a crossing vehicle in the im-
mediate vicinity, it can also warn the driver by issu-
ing a warning tone and displaying a corresponding
symbol in the instrument cluster and on the head-up
display.
If the function detects a collision risk when driving
slowly, a warning jolt is performed as a tactile warn-
ing at the last possible moment in order to draw the
driver's attention to the danger.
Functional limitations
– People and animals may not be detected.
– Cyclists may not always be detected.
– Vehicles approaching very fast or very slowly
may not always be detected in time.
– When turning off, if your vehicle is not facing in
the direction of the driving lane (but is inclined
diagonally, at a right angle to it or sharply upward
or downward), approaching vehicles may not be
detected or may not be detected in time.
– Highly reflective surroundings (e.g. steel bridges,
railings) can cause incorrect warnings or prevent
warnings from being issued.
– Acceleration or changes in the driving behavior of
crossing objects (e.g. sudden turn-offs) can
cause incorrect warnings or prevent warnings
from being issued.
