250 SAFETY
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of Anti-Lock Brakes. If the ABS
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
DROWSY DRIVER DETECTION (DDD) —
I
F EQUIPPED
DDD detects when the driver is feeling fatigued
and warns the driver to pull over and take a break.
To Activate/Deactivate
DDD can be activated and deactivated through the
Uconnect system by selecting the following in
order:
1. “Safety & Driving Assistance”
2. “Drowsy Driver Detection”
System Intervention
Using feedback obtained from the driver’s steering
patterns, any buttons/switches that are pressed,
and from the front camera, the system implements
two operating logics:
The first operating logic takes the driving style
into account, observing the road and detecting
to what extent the driver can continue driving
with few lane crossing events.
The second operating logic measures the time
spent behind the wheel with the vehicle speed
above 40 mph (60 km/h) and below 110 mph
(180 km/h).
NOTE:
If the conditions described above are not detected
continuously during the entire driving period, the
“Drowsy Driver” message may be displayed later
than two or three hours. If the driving style indi-
cates that the driver is unable to follow the road
trajectory and respect the horizontal lane
markings, the red symbol will appear on the
instrument cluster display to suggest that the
driver should stop for a break. An audible signal
will also sound.
If the driver accepts the suggestion provided by the
system by pushing the “OK” button on the left side
of the steering wheel, the message will disappear
from the display.
If the driver does not acknowledge the warning, it
will be displayed for 60 seconds and then
disappear.
NOTE:
In the event of a DDD system failure, a dedicated
message will appear in the instrument cluster
display.
DDD Warning Message
WARNING!
The DDD system is an aid for driving and does
not relieve the driver of the responsibility of
driving the vehicle. If you experience fatigue
while driving, pull over safely for a break without
waiting for the DDD to intervene. Only return to
the road when you are in the right physical and
mental condition to prevent endangering
yourself and other drivers.
