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 ignition is on.
.The exterior lamps control is
in AUTO.
.The light sensor determines it is
daytime.
.The parking brake is released or
the vehicle is not in P (Park).

When the DRL are on, the
low-beam headlamps will be on.
The taillamps, sidemarker lamps,
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.
This vehicle may have a DRL
disabling function. When the DRL
are on and a turn signal is activated,
the DRL on that side will be off until
the turn signal goes 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; otherwise 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.
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.
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

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 any burned out bulbs
replaced. If the bulb is not burned
out, check the fuse. See
Fuses and
Circuit Breakers on page 10‑35.

immediately by turning the exterior
lamps control 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.
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, 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 DIC message might
be displayed and it is recommended

Driving and Operating 9-19
The key lock release will not work if
the battery is charged less than
9 volts, or uncharged. Try charging
or jump starting the battery. See
Jump Starting (On-board with
eAssist Only) on page 10‑87or
Jump Starting (with or without
eAssist) on page 10‑87
If charging or jump starting the
battery does not work, there is a
manual key lock release. Locate the
hole below the ignition lock. Insert a
tool or key into the opening. Locate
the lever, and press it toward the
driver while removing the key from
the ignition.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only. Notice:
Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Notice: If you add electrical parts
or accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See Add-On Electrical Equipment
on page 9‑57.
Starting Procedure (Key Access)
1. With your foot off the accelerator pedal, turn the ignition key to
START. When the engine starts,
let go of the ignition.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts. The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START for many seconds,
cranking will be stopped after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also
prevents cranking if the engine
is already running. Engine
cranking can be stopped by
turning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
