Infotainment System 155
Introduction
Read the following pages to
become familiar with the
features.
{Warning
Taking your eyes off the
road for too long or too
often while using any
infotainment feature can
cause a crash. You or others
could be injured or killed. Do
not give extended attention
to infotainment tasks while
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, steering wheel
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.
See Distracted Driving 0234.
Active Noise
Cancellation (ANC)
If equipped, ANC reduces
engine noise in the vehicle’s
interior. ANC requires the
factory-installed audio system,
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.
Overview
Infotainment System
The infotainment system is
controlled by using the
infotainment display, controls
on the center console,
steering wheel controls, and
voice recognition.
