Hazard Warning Flashers
|(Hazard Warning Flashers):
Press this button to make the front
and rear turn signal lamps flash on
and off. This warns others that you
are having trouble. Press again to

are on, the vehicle's turn signals will
not work.
Turn and Lane-Change
Signals
G(Turn Signals):
An arrow on
the instrument cluster flashes in the
direction of the turn or lane change.
To signal a turn, move the lever all
the way up or down.
To signal a lane change, raise or
lower the lever until the arrow starts
to flash. The turn signal
automatically flashes three times
and if the Tow/Haul Mode is active it
flashes six times. Holding the turn
signal lever for more than one second causes the turn signals
to flash continually until the lever is
released.
The lever returns to its starting
position when released.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have any burned out bulbs
replaced. If a bulb is not burned out,
check the fuse. See
Fuses and
Circuit Breakers on page 10-34.Turn Signal On Chime
If the turn signal is left on for more
than 1.2 km (0.75 mi), a chime
sounds at each flash of the turn
signal and the message TURN
SIGNAL ON also appears in the
Driver Information Center (DIC). See
Lamp Messages on page 5-32. To
turn off the chime and message,
move the turn signal lever to the off
position.

lamps in other locations. The lamps
cannot be adjusted.
Lighting Features

E
DOME OFF button is in the
extended position, when a door is
opened, or the key is removed from

Battery Load
Management
The vehicle may have 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 vehiclehas 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 SERVICE
BATTERY CHARGING SYSTEM.
If this messages displays, it is
recommended that the driver reduce
the electrical loads as much as
possible. SeeBattery Voltage and
Charging Messages on page 5-29.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.

7-10 Infotainment System
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. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
FM Stereo
FM stereo gives the best sound, but
FM signals reach only about 16 to
65 km (10 to 40 mi). Tall buildings or
hills can interfere with FM signals,
causing the sound to fade in
and out.
Cellular Phone Usage
Cellular phone usage may cause
interference with the radio. This
interference may occur when
making or receiving phone calls,charging the phone's battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to the
radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
(Multi-Band)
The multi-band antenna is on the
roof of the vehicle. The antenna is
used for the Navigation System,
OnStar
®and the SiriusXM®Satellite
Radio Service System if the vehicle
has these features. Tall buildings,
hills, trees, heavy foliage, tunnels,
bridges, and garages will affect
reception. Keep the antenna clear of
obstructions for clear reception.
Make sure there is sufficient
clearance when entering garages or
parking structures.
Fixed Mast
Antenna (Care)
The fixed mast antenna can
withstand most car washes without
being damaged as long as it is
securely attached to the base. If the
mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Make sure there is sufficient
clearance when entering garages or
parking structures.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand.
