244 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
Changing the FCW status to the "Near" setting, allows
the system to warn you of a possible collision with the
vehicle in front of you when you are much closer. This
setting provides less reaction time than the "Far" setting,
which allows for a more dynamic driving experience.
Example Only
Changing the FCW status to "Off" prevents the system
from warning you of a possible collision with the vehicle
in front of you.
Example Only
NOTE: In the "Off" setting FCW OFF will be displayed
in the EVIC.
