Lighting Features
Entry Lighting
The headlamps, taillamps, back-up
lamps, license plate lamps, dome
lamps, and most of the interior lights
turn on briefly at night when
Kis
pressed on the Remote Keyless
Entry (RKE) transmitter. See Ignition
Positions on page 9-16. After about
30 seconds the exterior lamps turn
off, then the dome and remaining
interior lamps dim to off. Entry
lighting can be disabled manually by
changing the ignition out of the OFF
position, or by pressing
Qon the
RKE transmitter.
This feature can be turned on or off.
See “Vehicle Locator Lights” under
Vehicle Personalization on
page 5-47.
Exit Lighting
The headlamps, taillamps, back-up
lamps, parking 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 lamps and
dome lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
If equipped with Keyless Access,
the exterior lamps and dome lamps
automatically turn on when the
driver door is opened after the
ignition is turned off. See Ignition
Positions on page 9-16.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization on
page 5-47.
Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
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
