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 will make either
the reduced intensity low‐beam
headlamps or dedicated DRLs come
on when the following conditions
are met:
.It is still daylight and the ignition
is in ON/RUN or START.
.The exterior lamp control is in off
or AUTO and the headlamps
are off.
.The automatic transmission is
not in P (Park).
When DRLs are on, only the
reduced intensity low‐beam
headlamps or dedicated DRLs will be on. The other exterior lamps and
the instrument panel cluster will not
be on.
When the exterior lamp control is in
AUTO and it is dark enough outside,
the DRL turns off and the low-beam
headlamps will turn on. When it is
bright enough outside, the low-beam
headlamps will go off, and the DRL
will turn back on. If the vehicle is
started in a dark garage, the
automatic headlamp system comes
on immediately. Once the vehicle
leaves the garage, it takes about
one minute for the automatic
headlamp system to change to DRL
if it is light outside. During that
delay, the instrument panel cluster
may not be as bright as usual. Make
sure the instrument panel brightness
lever is in the full bright position.
See
Instrument Panel Illumination
Control on page 6‑5.
Turning the exterior lamp control to
off or to the low-beam headlamp
position will turn off the DRL. If the parking lamps or the fog lamps were
turned on instead, the DRL will still
turn off.
This will work regardless of gear
position and whether or not the
parking brake is set.
Automatic Headlamp
System
When it is dark enough outside and
the exterior lamps control is in the
automatic position, the headlamps
come on automatically. See
Exterior
Lamp Controls on page 6‑1.
The vehicle has a light sensor
located on top of the instrument
panel. Make sure it is not covered,
or the headlamps will be on when
they are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.

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 on
the multifunction lever to the AUTO
position. Moving the switch out of
the AUTO position will deactivate
the system. AFL will operate when
the vehicle speed is greater than
3 km/h (2 mph). AFL will 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 near the audio
system, to make the front and rear
turn signal lamps flash on and off.
This warns others that you are
having trouble. Press again to turn
the flashers off.
Turn and Lane-Change
Signals
An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Move the lever all the way up or
down to signal a turn. Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it briefly until the lane
change is complete. The arrow will
automatically flash three times.
The lever returns to its starting
position when it is 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 the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakers
on
page 10‑42.
Turn Signal On Chime
If the turn signal is left on for about
1.6 km (1 mile), a warning chime will
sound and the TURN SIGNAL ON
message will appear on the Driver
Information Center (DIC) display.
See “Turn Signal On” underDriver
Information Center (DIC)
on
page 5‑27for more information.

in foggy or misty conditions. The fog
lamp control is located on the turn
signal/multifunction lever.
#(Fog Lamps): Turn the fog lamp
band on the lever up to
#and
release it, to turn the fog lamps on
or off. The band will return to its
original position.
The parking lamps must be on for
the fog lamps to work.
If the high-beam headlamps are
turned on, the fog lamps will also
turn off. They will turn back on again
when you change back to low-beam
headlamps.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.
Interior Lighting

Lighting Features
Entry Lighting
The headlamps, taillamps, license
plate lamps, reverse lamps, dome
lamps, and most of the interior lights
turn on briefly, when the Remote
Keyless Entry (RKE)
Kis pressed,
or when the door handle is pulled on
a Keyless Access Vehicle. See
Ignition Positions (Key Access)
on
page 9‑16or Ignition Positions
(Keyless Access)on page 9‑18.
After about 30 seconds the exterior
lamps turn off, and then the dome
and remaining interior lights will dim
to off. Entry lighting can be disabled
manually by changing the ignition
out of the OFF position, or by
pressing the Remote Keyless Entry
(RKE)
Qbutton. This feature can be activated or
deactivated in the Settings menu in
the Info Display. Press the
customization button to call up the
menu. See
Vehicle Personalization
on page 5‑45.
Parade Dimming
This feature does not let the
instrument panel backlight dim
during daylight hours while the key
is in the ignition and the headlamps
are on. Parade dimming
automatically works with the light
sensor, located on top of the
dashboard. If it is dark enough
outside and the parking lamps are
on, the backlight on the instrument
panel can be adjusted by turning the
instrument panel brightness knob
clockwise or counterclockwise to
brighten or dim the lighting. See
Instrument Panel Illumination
Control on page 6‑5.
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.

Lighting 6-7
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
SAVER ACTIVE or BATTERY
VOLTS LOW. If this message is
displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. See
Driver
Information Center (DIC)
on
page 5‑27.
Battery Power Protection
This feature helps to prevent battery
drain if accessory lamps are left on.
If accessory lamps such as the
vanity mirror, cargo, reading,
console, or glove box are left on,
they automatically time-out after
about 20 minutes. To reset the
battery protection, all of the above
lamps must be turned off or the
ignition must be in the ACC/
ACCESSORY position.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned to LOCK/OFF, if the parking
lamps or headlamps have been left
on. This protects against draining
the battery. The battery saver does
not work if the headlamps are
turned on after the ignition is turned
to LOCK/OFF.
To keep the lamps on for more than
10 minutes, turn the lamps back on
with the exterior lamp control.
