Driving with IntelliBeam
The system only activates the high beams
when driving over 40 km/h (25 mph).
The blue high-beam on light appears on the
instrument cluster when the high beams
are on.
There is a sensor near the top center of the
windshield that automatically controls the
system. Keep this area of the windshield
clear of debris to allow for best system
performance. The high-beam headlamps remain on, under
the automatic control, until one of the
following situations occurs:
.The system detects an approaching
vehicle's headlamps.
.The system detects a preceding vehicle's
taillamps.
.The outside light is bright enough that
high-beam headlamps are not required.
.The vehicle's speed drops below 20 km/h
(12 mph).
.The IntelliBeam system is disabled by the
button on the turn signal lever. If this
happens, press
bon the turn signal
lever when the exterior lamp control is in
the AUTO or
5position to reactivate the
IntelliBeam system. The instrument
cluster light will come on to indicate the
IntelliBeam system is reactivated.
The high beams may not turn off
automatically if the system cannot detect
another vehicle's lamps because of any of
the following:
.The other vehicle's lamps are missing,
damaged, obstructed from view,
or otherwise undetected.
.The other vehicle's lamps are covered
with dirt, snow, and/or road spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust, smoke,
fog, snow, road spray, mist, or other
airborne obstructions.
.The vehicle's windshield is dirty, cracked,
or obstructed by something that blocks
the view of the light sensor.
.The vehicle is loaded such that the front
end points upward, causing the light
sensor to aim high and not detect
headlamps and taillamps.
.The vehicle is being driven on winding or
hilly roads.
The IntelliBeam system may need to be
disabled if any of the above conditions exist.

Automatic Headlamp System
When the exterior lamp control is set to
AUTO and it is dark enough outside, the
headlamps come on automatically.
There is a light sensor on top of the
instrument panel. Do not cover the sensor.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel. If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system changes to the Daytime Running
Lamps (DRL). During that delay, the
instrument cluster may not be as bright as
usual. Make sure the instrument panel
brightness control is in the full bright
position. See
Instrument Panel Illumination
Control 0124.

Battery Load Management
The vehicle has Electric Power Management
(EPM) that 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 the state 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 of the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, rear window defogger, climate
control fan at high speed, heated seats,
engine cooling fans, trailer loads, and loads
plugged into accessory power outlets.

14608203) - 2021 - CRC - 10/29/20
Lighting 127
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 battery voltage and
charging message displays. It is
recommended that the driver reduce the
electrical loads as much as possible. See
Driver Information Center (DIC) (Base and
Midlevel)0107 or
Driver Information Center (DIC) (Uplevel)
0 110.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This will keep the
battery from draining.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition 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 off position
and then back to the parking lamp or
headlamp position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.

154 Infotainment System
Voice Recognition
If equipped, voice recognition allows for
hands-free operation within the navigation,
audio, phone, and weather applications. This
feature can be started by pressing
gon the
steering wheel or touching
gon the
infotainment display.
However, not all features within these areas
are supported by voice commands.
Generally, only complex tasks that require
multiple manual interactions to complete
are supported by voice commands.
For example, tasks that take more than one
or two touches, such as a song or artist to
play from a media device, would be
supported by voice commands. Other tasks,
like adjusting the volume or seeking up or
down, are audio features that are easily
performed by touching one or two options,
and are not supported by voice commands.
In general there are flexible ways to speak
commands for completing the tasks.
If your language supports it, try stating a
one-shot command, such as “Directions to
address province>.” Do not include the ZIP code
while stating the address during the command. Another example of a one-shot
Destination Entry command is,
“Directions to
Place of Interest at .” If these
commands do not work, try saying, “Take
me to Place of Interest” or“Find address”
and the system will walk you through by
asking additional questions.
Hybrid Speech Recognition
If equipped, this feature helps distinguish
words by using Internet-based information
along with the system’s voice recognition
database. This allows you to speak more
naturally when using voice recognition.
Using Voice Recognition
Voice recognition becomes available once
the system has been initialized. This begins
when the ignition is turned on. Initialization
may take a few moments.
1. Press
gon the steering wheel controls
to activate voice recognition.
2. The audio system mutes and the system plays a prompt.
3. Clearly speak one of the commands described in this section.
A voice recognition system prompt can
be interrupted while it is playing by
pressing
gagain. Once voice recognition is started, both the
infotainment display and instrument cluster
show the selections and visual dialog
content. These displays can be turned on or
off in the Tutorial Mode under
Settings
0 164.
There are three voice prompt modes
supported:
.Informative verbal prompts: This type of
prompt will provide more information
regarding the supported actions.
.Short prompts: This type of prompt will
provide simple instructions about what
can be stated.
.Auto informative prompts: This type of
prompt plays during the first few speech
sessions, then automatically switches to
the short prompt after some experience
has been gained through using the
system.
If a command is not spoken, the voice
recognition system says a help prompt.
Prompts and Infotainment Displays
While a voice recognition session is active,
there may be corresponding options
showing on the displays. A selection can be
made by manually touching the option,
or by speaking the number for the option to
