DA 5.0 Side Guard Assist
(SGA)
General Information
IMPORTANT: Side guard assist (SGA) is de-
signed for use with one trailer attached to the
tractor. SGA detects if a trailer is attached to the
tractor, but it cannot detect whether or not mul-
tiple trailers are attached. If used with more than
one trailer, SGA only considers objects or sta-
tionary obstacles in the range of the tractor and
the first trailer. False-positive indications and
warnings may occur with multiple trailers.
IMPORTANT: Side Guard Assist is not currently
designed to work with non-ABS trailers or on
trucks with lift axles.
In a left-hand drive vehicle, Detroit Assurance 5.0
Side Guard Assist (SGA) monitors the area to the
right of the vehicle and trailer using two short range
radar sensors. The radar sensors are mounted close
to the rear of the right-hand footsteps. SGA provides
assistance when turning right and changing lanes to
the right. A yellow triangular warning lamp in the
A-pillar lights up to inform the driver that an object
has been detected in the monitored area. An addi-
tional warning tone sounds if there is a risk of colli-
sion.
SGA is not active while reversing.
The trailer monitoring of SGA is not active shortly
after reversing or shortly after coupling up. It is not
possible to switch SGA trailer monitoring on or off
shortly after reversing or shortly after coupling up.
For a right-hand drive vehicle, SGA monitors the
area to the left of the vehicle and trailer. The location
of sensors and warning lamps on the ICU all shift to
the left in this case. All other features remain the
same.
Safety Information
WARNING
When detection is restricted, Side Guard Assist
may issue a warning too late or not at all. The
detection of obstacles can be impaired by the
following situations:
•
dirty, icy or obscured sensors;
•
very wide lanes;
•
vehicles not driving in the middle of their
lane;
•
barriers or other road boundaries.
There is a risk of an accident in these situations.
The driver must pay attention to the traffic situa-
tion and maintain a safe distance at the side of
the vehicle.
Side Guard Assist is only an aid. It may fail to detect
some objects and is not a substitute for attentive
driving. Always ensure there is sufficient distance to
the side for other vehicles, pedestrians, and ob-
stacles.
IMPORTANT: If the sensors are dirty or Side
Guard Assist malfunctions, an alert icon will dis-
play in the instrument panel. See the third icon
in
Table 6.3 . Objects in the monitoring range
are not tracked when this occurs.
If the sensors are dirty, pull off in a safe location
to clean the SGA sensors.
If SGA malfunctions, have the function of the
radar sensors checked at an authorized Freight-
liner dealer.
Before driving the vehicle, ensure the radar sensor
cover is free from dirt, ice, or slush. See
Fig. 6.10.
The radar sensors must not be painted or covered by
items such as stickers.
If the vehicle is involved in a severe accident or there
is damage to the right-hand footsteps, have the func-
tion of the radar sensors checked at an authorized
Freightliner dealer.
Monitoring Range of the Sensors
There is an angle of approximately 6 degrees be-
tween the vehicle and the area monitored by the
sensor. See
Fig. 6.11 . Objects within this area are
not detected.
Due to the nature of the system, warnings may be
issued in error when driving close to barriers or other
solid boundaries. Warnings may also be interrupted
when driving alongside particularly long vehicles for a
prolonged time.
Depending on the situation and on the trailer, Side
Guard Assist may issue a warning prematurely or not
issue a warning at all.
