The infotainment system has built-in
features intended to help with this
by disabling some functions when
driving. Some functions may
gray-out when the vehicle is
moving, indicating they are
unavailable.
All functions are available when the
vehicle is parked. Before driving:
Become familiar with the
infotainment system operation
and buttons on the faceplate.
Set up the audio by presetting
favorite stations, setting the
tone, and adjusting the
speakers.
Set up phone numbers in
advance so they can be called
easily by pressing a single
button or by using a single voice
command for vehicles equipped
with phone capability.
