Active Lane Assist Safety Information
Active Lane Assist (ALA) cannot always clearly iden-
tify lane markings. In such cases, ALA may go into
passive mode.
Active Lane Assist may go into passive mode under
the following conditions:
•
there is low visibility, due to insufficient road
illumination or due to snow, rain, fog, or heavy
spray;
•
there is glare from oncoming traffic, the sun, or
reflection from other vehicles when the road
surface is wet;
•
the windshield is dirty, misted up, damaged, or
covered in the vicinity of the camera;
•
there are unclear lane markings present, such
as a construction area;
•
the lane markings are worn away, dark, or cov-
ered by dirt, sand, water, or snow;
•
the distance to the vehicle in front is too small
and the lane markings cannot be detected;
•
the lane markings change quickly—for example
lanes branch off, cross one another or merge;
•
the road is narrow and winding;
•
there are variable shade conditions on the road
surface;
•
an attachment (such as a snow plow) restricts
the camera’s view of the lane markings;
•
there has been a significant change in load
with the ignition switched on. Start the engine
again after a significant change in load to have
ALA be available without restrictions.
Active Lane Assist cannot take the road and weather
conditions into account, nor the current traffic situa-
tion. The driver is responsible for the distance to the
vehicle in front, for vehicle speed, braking in good
time and remaining in the lane.
Keep the windshield clean and unobstructed in the
area of the camera.
Active Lane Assist Overview
IMPORTANT: Adaptive Cruise Control (ACC)
must be active for Active Lane Assist (ALA) to
be active. Deactivation of ACC also deactivates
ALA.
Detroit Assurance 5.0 Active Lane Assist consists of
Lane Departure Protection (LDP), a feature that
builds on Lane Departure Warning (LDW), and Lane
Keep Assist (LKA).
When Active Lane Assist is on, it monitors the area
in front of the vehicle with the multipurpose camera
mounted at the top of the windshield. The LDW/LDP
function of ALA detects lane markings on the road
surface, warns the driver they may be leaving their
lane unintentionally, and, if a driver does not respond
to these warnings, moves the vehicle back to the
center of the lane. The Lane Keep Assist (LKA) func-
tion of ALA monitors the driver’s steering behavior
and uses micro-steering adjustments to keep the ve-
hicle in the driver’s preferred lane position.
Active Lane Assist (ALA) Activation
Conditions and Functions
Active Lane Assist is turned on each time the engine
is turned on.
Lane Departure Protection (LDP) builds on Lane De-
parture Warning (LDW). As soon as the vehicle
reaches 37 mph (60 km/h), both Lane Departure
Warning (LDW) and Lane Departure Protection
(LDP) are on.
Lane Departure Protection (LDP) requires both lane
lines to be identifiable to function.
Active Lane Assist is ready to issue warnings:
•
when the vehicle is moving above approxi-
mately 37 mph (60 km/h); and
•
the driver display shows solid lane markings;
and
•
when the blue steering wheel indicator appears
in the instrument panel.
When driving over the lane marking unintentionally:
•
the relevant lane marking is shown in red on
the driver display screen;
•
the volume of the audio equipment and/or
hands-free system is muted and a warning
tone sounds from the loudspeaker on the cor-
responding side of the vehicle.
If a driver takes their hands off the steering wheel for
fifteen seconds:
•
a "Hands On" caution pop-up screen will ap-
pear.
Active Lane Assist does not issue a warning about
going over lane markings if:
