Highway Driving Assist system helps
keep the vehicle between lanes, maintain
a distance with the vehicle ahead, and
automatically adjusts the vehicle speed
to the speed limit while driving on the
highway.
WARNING
• Highway Driving Assist system is
not a substitute for safe driving
practices, but a convenience
function. It is the responsibility of
the driver to always be aware of the
surroundings and drive safely.
• Highway Driving Assist system relies
entirely on the road information
provided by the navigation system.
It is the responsibility of the driver
to follow traffic laws and avoid
accidents.
• For your safety, please read the
owner's manual before using the
system.
Information
• Highway Driving Assist system is
available only on controlled access road of certain highways.  Controlled access road indicates
