The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. The
other lamps that come on with the
headlamps will also come on.
When it is bright enough outside,
the headlamps will go off and the
DRL will come on.
The regular headlamp system
should be turned on when needed.
Do not cover the light sensor on top
of the instrument panel because it
works with the DRL.Delayed Headlamps
Delayed headlamps provide a
period of exterior lighting as you
leave the area around the vehicle.
This feature is activated when the
headlamps are on due to the
automatic headlamps control feature
and when the ignition is turned off.
The headlamps remain on until the
exterior lamp control is moved to the
parking lamps position or until the
pre-selected delayed headlamp
lighting period has ended.
If the ignition is turned off with the
exterior lamp control in the
;
or5position, the delayed
headlamps cycle will not occur.
To disable the delayed headlamps
feature or change the time of delay,
see Vehicle Personalization on
page 5-42.

Lighting Features
Entry Lighting
For vehicles with courtesy lamps,
they come on and stay on for a set
time whenever
Kis pressed on the
Remote Keyless Entry (RKE)
transmitter.
If a door is opened, the lamps stay
on while it is open and then turn off
automatically about 20 seconds
after the door is closed. If
Kis
pressed and no door is opened, the
lamps turn off after about
20 seconds.
Entry lighting includes a feature
called theater dimming. With theater
dimming, the lamps do not turn off
at the end of the delay time.
Instead, they slowly dim and then
go out. The delay time is canceled if
the ignition key is turned to ON/RUN
or the power door lock switch is
pressed. The lamps will dim
right away.

Lighting 6-7
When the ignition is on, illuminated
entry is inactive, which means the
courtesy lamps will not come on
unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates
the interior for a period of time after
all the doors have been closed.
The ignition must be off for delayed
entry lighting to work. Immediately
after all the doors have been closed,
the delayed entry lighting feature
continues to work until one of the
following occurs:
.The ignition is in ON/RUN.
.The doors are locked.
.An illumination period of about
25 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period is canceled and
the interior lamps remain on.
Delayed Exit Lighting
Delayed exit lighting illuminates the
interior for a period of time after the
key is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
.The ignition is in ON/RUN.
.The power door locks are
activated.
.An illumination period of
20 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period will be canceled
and the interior lamps will remain on
because a door is open.
Parade Dimming
This feature automatically prohibits
the dimming of the instrument panel
displays in daylight while the
headlamps are on so that the
displays are still able to be seen.
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

Mexico-7576030) - 2015 - CRC - 8/18/14
6-8 Lighting
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, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays, it
is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5-23.Battery Power Protection
This feature helps prevent the
battery from being drained, if the
interior courtesy lamps or reading
lamps are accidentally left on. If any
of these lamps are left on, they
automatically turn off after
10 minutes, if the ignition is off. The
lamps will not come back on again
until one of the following occurs:
.The ignition is turned on.
.The exterior lamps control is
turned off, then on again.
The headlamps will time out after
10 minutes, if they are manually
turned on while the ignition is on
or off.

Using recirculation for long periods
of time could cause the air inside
the vehicle to become too dry. To
prevent this from happening, after
the inside of the vehicle has cooled,
turn the recirculation mode off.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when
recirculation is on. When the engine
is turned off, the recirculation mode
automatically turns off and must be

This mode recirculates and helps to
quickly cool the air inside the
vehicle. It can be used to reduce the
outside air and odors that may enter
the vehicle.
The recirculation mode cannot be
used with floor, defrost, or defogging
modes. If recirculation is selected in these modes, the indicator flashes
three times and turns off. The air
conditioning also comes on when
this mode is activated unless the
outside air temperature is less than
4°C (40°F). While in recirculation
