Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system turns on the
low-beam headlamps at a reduced
brightness. For vehicles with
High Intensity Discharge (HID)
headlamps, the dedicated DRL
will come on when all of the
following conditions are met:
.The engine is running.
.The exterior lamp band is
in AUTO.
.The light sensor determines it is
daytime.When the DRL are on, the
low-beam headlamps will be
on. The taillamps, sidemarker,
instrument panel lights, and
other lamps will not be on.
The DRL turn off when the
headlamps are turned to
Oor
the ignition is off.
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 located on
top of the instrument panel. Do not
cover the sensor or the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through
a parking garage or tunnel.
When it is bright enough outside,
the headlamps will turn off or may
change to Daytime Running
Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off.

6-4 Lighting
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlamps
horizontally to provide greater
road illumination while turning.
To enable AFL, set the exterior
lamp switch to the AUTO position.
Moving the switch out of the AUTO
position deactivates the system.
AFL operates when the vehicle
speed is greater than 3 km/h
(2 mph). AFL does not operate
when the transmission is in
R (Reverse). AFL is not immediately
operable after starting the vehicle;
driving a short distance is required
to calibrate the AFL. SeeExterior
Lamp Controls on page 6‑1.
Hazard Warning Flashers
|
Hazard Warning Flasher:
Press this button located on the
instrument panel below the climate
control system, to make the front
and rear turn signal lamps flash
on and off. Press again to turn the
flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn. An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane‐change signal
can be turned off manually by
moving the lever back to its
original position.
If after signaling a turn or lane
change the arrow flashes rapidly
or does not come on, a signal bulb
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakers on
page 10‑39.

Lighting Features
Entry Lighting
The headlamps, taillamps, license
plate lamps, back‐up lamps, dome
lamps, and most of the interior lights
turn on briefly, when the Remote
Keyless Entry (RKE)
Kbutton is
pressed, or when the door handle is
pulled on a keyless access vehicle.
See Ignition Positions (Key Access)
on page 9‑17 orIgnition Positions
(Keyless Access) on page 9‑19.
After about 30 seconds the exterior

areas with limited lighting, when the
key is removed from the ignition.
The dome lamps also come on
when the key is removed from the
ignition. The exterior lights and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
For a vehicle with keyless access,
the exterior lights and dome lamps
automatically turn on when a door
is opened after the ignition is turned

exterior lamps control to OFF.
This feature can be changed.
See Vehicle Personalization on
page 5‑39.
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.

7-38 Infotainment System
The headphones are used to listen
to various multi‐media. The wireless
headphones have an On/Off button,
channel 1/2 switch, and a volume
control. Turn the headphones off
when not in use.
Push the On/Off button to turn
on the headphones. A light on
the headphones comes on. If the
light does not come on, check the
batteries. Intermittent sound or static
can also indicate weak batteries.
See“Battery Replacement” later in
this section for more information.
Infrared transmitters are on the
top of the left seatback video
screen. The headphones shut off
automatically to save the battery
power if the RSE system is shut
off or if the headphones are out
of range of the transmitters for
more than three minutes. Moving
too far forward or stepping out of the
vehicle can cause the headphones
to lose the signal or have static. To adjust the volume on the
headphones, use the volume
control.
For optimal audio performance, the
headphones must be worn correctly.
Headphones should be worn with
the headband over the top of the
head for best audio reception.
The symbol L (Left) appears on the
outside bottom edge of the ear cup
and should be positioned on the left
ear. The symbol R (Right) appears
on the outside bottom edge of the
ear cup and should be positioned
on the right ear.
Notice:
Do not store the
headphones in heat or direct
sunlight. This could damage
the headphones and repairs will
not be covered by the warranty.
Storage in extreme cold can
weaken the batteries. Keep the
headphones stored in a cool,
dry place. If the foam ear pads attached to
the headphones become worn or
damaged, the pads can be replaced
separately from the headphone set.
To purchase replacement ear pads,
call 1‐888‐293‐3332, then prompt
zero (0), or contact your dealer.
Battery Replacement

1. Loosen the screw to the battery
door located on the left side of
the headphones.
2. Slide the battery door open.
3. Replace the two AAA batteries.
4. Replace the battery door and tighten the screw.
