Reminder
If a door is open, a reminder chime
sounds when the headlamps or
parking lamps are manually turned
on and the key is out of the ignition.
To turn off the chime, turn the
headlamp switch to
Oor AUTO and
then back on, or close and re‐open
the door. In the auto mode, the
headlamps turn off once the ignition
is in LOCK/OFF or may remain on
until the headlamp delay ends,
if enabled in the Driver Information
Center (DIC). See “Exit Lighting”
under Vehicle Personalization

(Headlamp High/Low-Beam
Changer) : Pull the turn signal lever
all the way toward you to change
the headlamps from low to high
beam. Then release it.
This instrument cluster light comes
on when the high-beam headlamps
are on.
Flash-to-Pass
This feature is used to signal to the
vehicle ahead that you want
to pass.
If the headlamps are off or in the
low‐beam position, pull the turn
signal lever toward you to
momentarily switch to high beams.
Release the lever to turn the
high-beam headlamps off.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of the vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada. The DRL system comes on in
daylight when the following
conditions are met:
.
The ignition is on.
. The exterior lamp control is in
the AUTO position.
. The shift lever is not in P (Park).
. The light sensor determines it is
daytime.
When the DRL are on, the taillamps,
sidemarker, instrument panel lights,
and other lamps will not be on.
The automatic headlamp system
automatically switches from DRL to
the headlamps depending on the
darkness of the surroundings.
To turn off the DRL, turn the exterior
lamp control to
Oand then release
it. For vehicles first sold in Canada,
the transmission must be in the
P (Park) position, before the DRL
can be turned off.

Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps, along with
the taillamps, sidemarker lamps,
parking lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamp
control to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.
The vehicle has a light sensor on
the top of the instrument panel. Do
not cover the sensor; otherwise the
system will come on whenever the
ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system are only affected
when the light sensor sees a
change in lighting lasting longer
than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately 30 seconds
for the automatic headlamp system
to change to DRL if it is light
outside. During that delay, the
instrument cluster may not be asbright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control
0129.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
P
or;to disable this feature.

Reading Lamps
If equipped with reading lamps,
press the button next to each lamp
to turn it on or off.
The vehicle may also have reading
lamps in other locations. The lamps
cannot be adjusted.
Lighting Features
Entry/Exit Lighting
The vehicle has an illuminated
entry/exit feature.
The dome lamps come on if the
E
DOME OFF button is in the
extended position, when a door is
opened, or the key is removed from
the ignition.
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 vehicle
has a voltmeter gauge or a voltage
display on the Driver InformationCenter (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.

170 Driving and Operating
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0317. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set
(Continued)
Warning (Continued)
the fan speed to the highest
setting. See“Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0182.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.

1. View displayed by thecamera
1. View displayed by thecamera 2. Corners of the rear bumper
Displayed images may be further or
closer than they appear. The area
displayed is limited and objects that
are close to either corner of the
bumper or under the bumper do not
display.
When the System Does Not
Seem To Work Properly
The RVC system might not work
properly or display a clear image if:
.
It is dark.
. The sun or the beam of
headlamps is shining directly
into the camera lens.
. Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft
cloth.
. The back of the vehicle is in an
accident. The position and
mounting angle of the camera
can change or the camera can
be affected. Be sure to have the camera and its position and
mounting angle checked at your
dealer.
The RVC system display in the
rearview mirror may turn off or not
appear as expected due to one of
the following conditions. If this
occurs, the left indicator light on the
mirror will flash.
. A slow flash may indicate a loss
of video signal, or no video
signal present during the reverse
cycle.
. A fast flash may indicate that the
display has been on for the
maximum allowable time during
a reverse cycle, or the display
has reached an Over
Temperature limit.
The fast flash conditions are
used to protect the video device
from high temperature
conditions. Once conditions
return to normal, the device will
reset and the indicator will stop
flashing.
