Drowsiness Alerts
Depending on the drowsiness level, Driver

in the instrument cluster. These alerts progress
as the drowsiness level increases. Each
level is designated by acoffee cup and
aDriver Information Center (DIC) message
recommending that the driver consider taking
arest break. Depending on the driver’s
drowsiness level, the system will also send
chimes or haptic alerts, if equipped with Safety
Alert Seat. The higher alerts will be seen more
frequently. Not all alerts may occur during
adrowsy event.
When the maximum drowsiness alert occurs,
th
e driver will be presented with the following
options on the infotainment screen:
•
Phone aFriend
•
Place an OnStar call
•
Navigate to Nearest Point of Interest (POI)
Select an option from the list and follow the
instructions displayed on infotainment screen.

may become dirty over time. If this occurs,
clean the lens cover with asoft cloth sprayed
with glass cleaner. Wipe the lens gently, then
dry it. Never use abrasive cloths, cleaners,
or corrosive chemicals of any kind on the
lens cover.

{ Warning
T
he LKA system does not continuously
st
eer the vehicle. It may not keep the

Provide an alert or enough steering
assist to avoid a lane departure or crash.

weather or visibility conditions. This can
occur if the windshield or headlamps are
blocked by dirt, snow, or ice, if they are
not in proper condition, or if the sun
shines directly into the camera.
