DA 5.0 Attention Assist
General Information
Detroit Assurance 5.0 Attention Assist helps a driver
by detecting typical indicators of fatigue or increasing
lapses in concentration and suggesting taking a
break.
Attention Assist is active at speeds above approxi-
mately 37 mph (60 km/h). When it detects indicators
of fatigue, Attention Assist sounds a warning tone
and displays a warning lamp on the instrument
panel.
The Attention Assist warning is shown regardless of
legally prescribed driving and rest periods.
Keep the windshield clean and unobstructed in the
area of the camera to help ensure Attention Assist is
working properly.
Safety Information
IMPORTANT: Attention Assist is only an aid. It
cannot always detect fatigue or lapses in con-
centration reliably or in time. Attention Assist is
not a substitute for a well-rested and attentive
driver.
Attention Assist may not operate as designed under
the following conditions:
•
low visibility due to insufficient road illumination
or due to snow, rain, fog, or heavy spray;
•
if the windshield is dirty in the area of the cam-
era, misted up, damaged, or covered by some-
thing such as a sticker;
•
no lane markings or several ambiguous lane
markings are present for a lane (near construc-
tion sites for example);
•
the lane markings are worn, dark, or covered
by dirt or snow;
•
there is glare due to oncoming traffic, direct
sunlight or reflections (from wet road surfaces
for example);
•
on winding roads;
•
when the distance to the vehicle in front is too
small for the lane markings to be detected;
•
when attachments, such as a snow plough,
restrict the camera’s view of the road lane
markings;
•
after a significant change in load with the igni-
tion turned on. Therefore, start the engine
again after a significant change in load for At-
tention Assist to be available without any re-
strictions.
Attention Assist is restricted and a warning does not
occur or is delayed:
•
if the driver is predominantly driving slower
than 37 mph (60 km/h);
•
if the markings on the road are missing or diffi-
cult to distinguish;
•
on winding roads.
Function and Activation Conditions
Attention Assist assesses the driver’s level of fatigue
or lapses in concentration by taking the following cri-
teria into account:
•
Driving characteristics, such as remaining in
the lane and active steering.
•
Trip related details such as the length of the
drive.
•
Use of turn signals.
•
Use of the engine brake switch.
•
Uncharacteristic changes in the accelerator
pedal position.
If Attention Assist detects typical indicators of fatigue
or increasing lapses in concentration on the part of
the driver:
•
a warning tone sounds;
•
the instrument panel display screen shows an
attention assist caution warning, see
Fig. 6.25
and Fig. 6.26 ;
•
Active Lane Assist (ALA), if deactivated, is au-
tomatically reactivated.
Take regular breaks during long journeys.
