Exit Lighting

The headlamps, taillamps, parking
lamps, reverse 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 a vehicle 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 (Keyless
Access) on page 8 18 or Ignition
Positions (Key Access) on
page 8 19.
The exterior lights turn off
immediately by turning the exterior
lamps control to OFF.
The exit lighting feature can be
activated, deactivated, or the
timeframe for the lighting can be
changed in the menu Settings in the
Info. Display. Press CONFIG on the
Infotainment system to access the
menu. See Vehicle Personalization
on page 4 38.
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.
