122 Lighting The DRL turn off when the
headlamps are turned to
O or the
ignition is off.
For vehicles first sold in Canada,
the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp
System When it is dark enough outside and
the exterior lamp control is in the
automatic position and the engine is
running, the headlamps come on
automatically. See Exterior Lamp
Controls 0 120 .
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
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 0 124 .
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
Por
; to disable this feature.
Adaptive Forward
Lighting (AFL) The AFL system adjusts the
headlamps to provide greater road
illumination in various driving
conditions.
To enable AFL, set the exterior lamp
control to the AUTO position.
Moving the control 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. See Exterior
Lamp Controls 0 120 .
Curve Lighting
The light beam pivots based on the
steering wheel position and vehicle
speed of at least 10 km/h (6 mph).
The headlamps shine at an angle of
up to 15 degrees to the right or left
of the direction of travel.
Corner Lighting
On tight bends or when making a
turn, depending on the steering
angle or the turn signal lamp, an
additional left or right reflector is
turned on to illuminate the road at a
right angle to the direction of travel.
It is activated up to a speed of
40 km/h (25 mph).

126 Lighting exterior lamps and dome lamps
remain on after the door is closed
for a set amount of time, then
automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization 0 114 .
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.
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
that the driver reduce the electrical
loads as much as possible. See
Driver Information Center (DIC)
0 110 .
Battery Power Protection The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
