Daytime Running Lamps (DRL)
DRL can make it easier for others to see the
front of your vehicle during the day. Fully
functional DRL are required on all vehicles
first sold in Canada.
The dedicated DRL will come on when all of
the following conditions are met:
.The ignition is on.
.The exterior lamp control is in AUTO.
.The light sensor determines it is daytime.
The taillamps, sidemarker lamps, instrument
panel lights, and other lamps will not be on.
When it begins to get dark, the automatic
headlamp system switches from DRL to the
headlamps.
To turn off the DRL, turn the exterior lamp
control to
Oand then release. For vehicles
sold in Canada, this control only works
when the vehicle is parked.
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 0132. When it is bright enough outside, the
headlamps will turn off or may change
to DRL.

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.

ambient conditions. The rear defog indicator
light does not come on during a remote
start.
If equipped, the heated seats will turn on if
it is cold outside or the ventilated seats will
turn on if it is hot outside. The heated and
ventilated seat indicator lights may not
come on during a remote start. If equipped,
the heated steering wheel will come on in a
remote start if it is cold outside. The heated
steering wheel indicator light may not
come on.
Sensors
The solar sensor, located in the defrost grille
in the middle of the instrument panel,
monitors the solar heat. Do not cover the
solar sensor or the system will not work
properly.
There is also an exterior temperature sensor
behind the front grille. This sensor reads the
outside air temperature and helps maintain
the temperature inside the vehicle. Any
cover on the front of the vehicle, could
cause a false reading in the displayed
temperature.
The climate control system uses the
information from these sensors to maintain
comfort settings by adjusting the outlet

into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Use of non-GM approved hood deflectors
can adversely affect the performance of
the system.
.Keep the path under all seats clear of
objects to help circulate the air inside the
vehicle more effectively.
.If fogging reoccurs while inYor\
modes with mild temperature throughout
the vehicle, turn on the air conditioner to
reduce windshield fogging.
Maintenance
Passenger Compartment Air Filter
The passenger compartment air filter
reduces dust, pollen, and other airborne
irritants from outside air that is pulled into
the vehicle. The filter will need to be
replaced periodically. See Maintenance
Schedule 0339.
Using the climate control system without an
air filter installed is not recommended.
Water or other debris could enter the
system and result in leaks or noises. Always
install a new filter when removing the old
filter.
For more information on filter replacement,
see your dealer.
Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.

204 Driving and Operating
Caution (Continued)
.Avoid making hard stops for the first
300 km (200 mi) or so. During this
time the new brake linings are not yet
broken in. Hard stops with new linings
can mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new
brake linings.
.Do not tow a trailer during break-in.
SeeTrailer Towing 0252 for the trailer
towing capabilities of the vehicle and
more information.
Following break-in, engine speed and load
can be gradually increased.
On new vehicles, the various mechanical and
electrical systems experience a “break-in”
period during the first 6 400 km (4,000 mi)
of routine driving. As the vehicle is driven,
the mechanical systems adjust to provide
optimal fuel economy and transmission shift
performance.
Electrical systems will adapt and calibrate
during the break-in period. A one-time
occurrence of clicks and similar vehicle
noises is normal during this process. Normal driving charges the vehicle’s battery
to achieve the best operation of the vehicle,
including fuel economy and the Stop/Start
System. See
Stop/Start System 0206.
Ignition Positions
The vehicle has an electronic keyless ignition
with pushbutton start.
The remote key must be in the vehicle for
the system to operate. If the pushbutton
start is not working, the vehicle may be
near a strong radio antenna signal causing
interference to the remote key system. See
Remote Key Operation 07.
To shift out of P (Park), the vehicle must be
on and the brake pedal must be applied. Stopping the Engine/LOCK/OFF (No Indicator
Lights) :
When the vehicle is stopped, press
ENGINE START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the ignition will
turn off, and Retained Accessory Power (RAP)
will remain active. See Retained Accessory
Power (RAP) 0208.
If the vehicle is in R (Reverse), D (Drive) or
L (Low), the vehicle will shift to P (Park), the
ignition will turn off, and Retained Accessory
Power (RAP) will remain active. If the vehicle
is in N (Neutral), the ignition will return to
accessory mode and display the message
SHIFT TO PARK in the Driver Information
Center (DIC). When the vehicle is shifted
into P (Park), the ignition will turn off.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags.
If the vehicle must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.

speed. The faster the vehicle speed, the
further back your vehicle will follow a
vehicle detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable gaps
may not be appropriate for all drivers and
driving conditions.
Changing the gap setting automatically
changes the alert timing sensitivity (Far,
Medium, or Near) for the Forward Collision
Alert (FCA) feature. SeeForward Collision
Alert (FCA) System 0237.
Alerting the Driver
With Head-Up Display
Without Head-Up Display If ACC is engaged, driver action may be
required when ACC cannot apply sufficient
braking because of approaching a vehicle
too rapidly.
When this condition occurs, the collision
alert symbol will flash on the windshield.
Either eight beeps will sound from the front,
or both sides of the Safety Alert Seat will
pulse five times. Touch the Settings icon on
the infotainment home page. Select
“Vehicle”
to display the list of available
options and select “Collision/Detection
Systems”.
See Defensive Driving 0192.
Approaching and Following a Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD, if equipped.
The vehicle ahead indicator only displays
when a vehicle is detected in your vehicle’s
path moving in the same direction. If this symbol is not displaying, ACC will not
respond to or brake for vehicles ahead.
ACC automatically slows the vehicle down
and adjusts vehicle speed to follow the
vehicle in front at the selected follow gap.
The vehicle speed increases or decreases to
follow the vehicle in front of you, but will
not exceed the set speed. It may apply
limited braking, if necessary. When braking
is active, the brake lights will come on. The
automatic braking may feel or sound
different than if the brakes were applied
manually. This is normal.
Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.
{Warning
When using ACC to pass a vehicle or
perform a lane change, the following
distance to the vehicle being passed may
be reduced. ACC may not apply sufficient
acceleration or braking when passing a
vehicle or performing a lane change.
