braking because you are approaching a
vehicle too rapidly.
•
The vehicle speed drops below about
20 mph (32 km/h).
•
A temporary condition prohibits Adaptive
Cruise Control from operating. See DIC
Warnings and Messages on page 264 for more
information.

The alert symbol will
flash on the HUD and a
warning beep will
sound when driver
action is required.
CAUTION:
{
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In
some cases, Adaptive Cruise Control may
not have time to slow your vehicle enough
to avoid a collision. Be ready to take
action and apply the brakes yourself. See
Defensive Driving on page 316.
