Blind Zone Steering Assist (BZSA)
{ Warning

Do not rely on Blind Zone Steering Assist
(B
ZSA) to prevent crashes. This system does
not replace the need to pay attention and
drive safely. Failure to use proper care
when driving may result in vehicle damage,
injury, or death.
•
BZSA performance may be affected by
weather and road conditions.
•
BZSA does not provide steering
assistance to avoid a vehicle that is in, or
has entered, your lane of travel.
•
BZSA will not prevent atowed trailer
from crossing into the adjacent lane.
Always monitor the trailer position
while towing to ensure it is in the
same lane as your vehicle. BZSA is
only designed to detect when your
vehicle unintentionally crosses detected
lane lines.
If equipped, the Blind Zone Steering Assist
(BZSA) system can detect a potential crash with
amoving vehicle in the lane you are entering.
It provides abrief, urgent turn of the steering
wh
eel to alert you to take action to avoid
acollision.
BZSA works with Lane Keep Assist (LKA) and
Lane Change Alert (LCA). BZSA operates when
the vehicle is in aforward gear, and only when
LKA and LCA are enabled and able to assist. See
Lane Keep Assist (LKA) 3276. See Lane Change
Alert (LCA) 3272.
BZSA will provide asteering correction when
your vehicle is about to leave the current lane
of travel, with the possibility of a collision with
avehicle in the adjacent lane. Unlike LKA, the
steering correction with BSZA will happen even
if your turn signal is on in the direction of
lane departure.
In addition to the BZSA steering intervention,
the A will turn amber, six beeps or six seat
pulses will occur, if equipped with Safety Alert
Seat, and 8 or | will flash on the
outside rear view mirror.
Driver Attention Assist
If equipped, Driver Attention Assist alerts
the driver to pay closer attention to the
road ahead. Driver Attention Assist uses
acamera-based Driver Monitoring System.
The Driver Monitoring System on the steering
co
lumn continually monitors the driver's
head movements and eye gaze location
to determine if the driver is drowsy or
fatigued. Depending on the level of the driver’s
distraction or drowsiness, Driver Attention
Assist will provide visual warnings, chimes,
and, if equipped, haptic movements to gently
guide the driver to look back at the road.
Sunglasses, hats, or other types of clothing that
change the shape of the head may interfere
with camera performance. To improve camera
performance, raise or lower the steering wheel,
or change the seat position.
