driving. Limit your glances at
the vehicle displays and
focus your attention on
driving. Use voice commands
whenever possible.
The infotainment system has
built-in features intended to
help avoid distraction by
disabling some features when
driving. These features may
gray out when they are
unavailable. Many infotainment features are also available
through the instrument cluster
and steering wheel controls.
Before driving:
.Become familiar with the
operation, center stack

controls, and infotainment
display.
.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 control or by using a
single voice command.

radio, speakers, amplifier (if
equipped), induction system,
and exhaust system to work properly. Deactivation is
required by your dealer if
related aftermarket equipment
is installed.
