Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
estimates the battery's
temperature and state of
charge. It then adjusts the
voltage for best performance
and extended life of the
battery.
When the battery's state of
charge is low, the voltage is
raised slightly to quickly bring
the charge back up. When thestate of charge is high, the
voltage is lowered slightly to
prevent overcharging. If the
vehicle has a voltmeter gauge
or a voltage display on the
Driver Information Center
(DIC), you may see the voltage
move up or down. This is
normal. If there is a problem,
an alert will be displayed.
The battery can be discharged
at idle if the electrical loads
are very high. This is true for
all vehicles. This is because
the generator (alternator) may
not be spinning fast enough at
idle to produce all the power
that is needed for very high
electrical loads.
A high electrical load occurs
when several of the following
are on, such as: headlamps,
high beams, fog lamps, rear
window defogger, climate
control fan at high speed,
heated seats, engine cooling
fans, and loads plugged into
accessory power outlets.
EPM works to prevent
excessive discharge of the
battery. It does this by
balancing the generator's
output and the vehicle's
electrical needs. It can
increase engine idle speed to
generate more power,
whenever needed. It can
temporarily reduce the power
demands of some accessories.
Normally, these actions occur
in steps or levels, without
being noticeable. In rare cases
at the highest levels of
corrective action, this action
may be noticeable to the
driver. If so, a DIC message
might be displayed. If a battery
message is displayed, it is
recommended that the driver
reduce the electrical loads as
much as possible. See Driver
Information Center (DIC) (Base
Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132.

Battery Power
Protection
This feature helps prevent the
battery from being drained,
if the interior courtesy lamps
or reading lamps are
accidentally left on. If any of
these lamps are left on, they
automatically turn off after
10 minutes, if the ignition is off.
The lamps will not come back
on again until one of the
following occurs:
.The ignition is turned on.
.The doors are closed and
then re-opened.
Exterior Lighting
Battery Saver
The exterior lamps turn off
about 10 minutes after the
vehicle is turned off, if the
parking lamps or headlamps
have been manually left on.This protects against draining
the battery. To restart the
10-minute timer, turn the
exterior lamp control to the
O
position and then back to the
;or2position.
To keep the lamps on for more
than 10 minutes, the vehicle
must be on or in
accessory mode.

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.
