The fog lamps will go off whenever
your high-beam headlamps come
on. When the high beams go off,
the fog lamps will come on again.
The fog lamps will be cancelled
after the ignition is turned off. If you
still want to use the fog lamps after
you restart the vehicle, you will need
to press the fog lamp button again.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.
Exterior Cargo Lamps
The cargo lamp can be used if more
light is needed in the cargo area of
the vehicle or in the top-box storage
units. Some vehicles will only have
a cargo lamp in the driver side
top box.
The cargo lamps come on by
turning on the interior dome lamps.

Brightness): This feature controls
the brightness of the instrument
panel lights and is located next to
the exterior lamps control.

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 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,
trailer loads, 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 Driver Information
Center (DIC) message might be
displayed, such as BATTERY LOW
START VEHICLE . If this message
displays, it is recommended that the
driver reduce the electrical loads as
much as possible and restart the
vehicle. See
Battery Voltage and
Charging Messages on page 5‑37.Battery Power Protection
This feature shuts off the dome
lamps if they are left on for more
than 10 minutes when the ignition is
in LOCK/OFF. This helps to prevent
the battery from running down.

Introduction
Determine which radio the vehicle
has and read the following pages to
become familiar with its features.
{WARNING
Taking your eyes off the road for
extended periods could cause a
crash resulting in injury or
death to you or others. Do not
give extended attention to
entertainment tasks while driving.
This system provides access to
many audio and non‐audio listings. To minimize taking your eyes off the
road while driving, do the following
while the vehicle is parked:
.Become familiar with the
operation and controls of the
audio system.
.Set up the tone, speaker
adjustments, and preset
radio stations.
For more information, see Defensive
Driving on page 9‑2.
Notice: Contact your dealer
before adding any equipment.
Adding audio or communication
equipment could interfere with
the operation of the vehicle's
engine, radio, or other systems,
and could damage them. Follow
federal rules covering mobile
radio and telephone equipment. The vehicle has Retained
Accessory Power (RAP). With RAP,
the audio system can be played
even after the ignition is turned off.
See
Retained Accessory Power
(RAP) on page 9‑34 for more
information.Navigation/Radio System
For vehicles with a navigation radio
system, see the separate Navigation
System Manual.
Theft-Deterrent Feature

Speed Compensated Volume
(SCV): Radios with Speed
Compensated Volume (SCV)
automatically adjusts the radio

volume level stays consistent.
To activate SCV:
1. Set the radio volume to the
desired level.
2. Press the MENU button to display the radio setup menu.
3. Press the softkey under the AUTO VOLUM (automatic
volume) tab on the radio display. 4. Press the softkey under the

compensation at faster
vehicle speeds.
Noise Compensation
Technology: Vehicles with the
LTZ package and a Bose Audio
System include the Bose
AudioPilot
®noise compensation
technology. When turned on,
AudioPilot continuously adjusts the
audio system equalization, to
compensate for background noise,
so that music always sounds the
same at the set volume level. This feature is most effective at
lower radio volume settings where
background noise can affect how
well the music is heard. At higher
volume settings, where the music is
much louder than the background
noise, there might be little or no
adjustments by AudioPilot.
To activate:
1. Set the radio volume to the
desired level.
2. Press the MENU button to display the radio setup menu.
3. Press the softkey under the AUTO VOLUM (automatic
volume) tab on the radio display.
4. Press the softkey under the ON tab. The display times out
after approximately 10 seconds.

Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug
the item from the accessory
power outlet.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night.
