Lighting Features
Entry Lighting
The headlamps, taillamps, license
plate lamps, back‐up lamps, dome
lamps, and most of the interior lights
turn on briefly when the Remote
Keyless Entry (RKE)
Kbutton is
pressed, or when the door handle is
pulled on a keyless access vehicle.
See Ignition Positions (Key Access)
on page 9‑18 orIgnition Positions
(Keyless Access) on page 9‑20.
After about 30 seconds the exterior
lamps turn off, then the dome lamps
and remaining interior lights dim to
off. Entry lighting can be disabled
manually by changing the ignition
out of the OFF position, or by
pressing the RKE
Qbutton.
This feature can be changed. See
Vehicle Personalization on
page 5‑43.
Exit Lighting
The headlamps, taillamps, parking
lamps, back‐up lamps, and license
plate lamps come on at night, or in
areas with limited lighting, when the
key is removed from the ignition.
The dome lamps also come on
when the key is removed from the
ignition. The exterior lights and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
For vehicles with keyless access,
the exterior lights and dome lamps
automatically turn on when a door is
opened after the ignition is turned
off. See Ignition Positions (Key
Access) on page 9‑18 orIgnition
Positions (Keyless Access) on
page 9‑20.
The exterior lights turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization on
page 5‑43.
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.

6-8 Lighting
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
that the driver reduce the electrical
loads as much as possible. See
Battery Voltage and Charging
Messages on page 5‑35.Battery Power Protection
The battery saver feature is
designed to protect the vehicle's
battery.
If the exterior lamps or any interior
light is left on and the ignition is
turned off, the battery rundown
protection system automatically
turns the lamp off after about
10 minutes.
