Entry Lighting
Your vehicle has an illuminated entry feature.
When the doors are opened, the dome lamps will
come on if the dome override button is in the
extended position. If the dome override button is
pressed in, the lamps will not come on.

With exit lighting, the interior lamps will come on
when the key is removed from the ignition. They
will turn off automatically in 20 seconds. The lights
will not come on if the dome override button is
pressed in.
Reading Lamps
If your vehicle has reading lamps they are located
on the overhead console.
To turn on the reading lamps, press the button
located next to each lamp. To turn them off, press
the button again.Your vehicle may also have reading lamps in other
locations. To turn the lamps on or off, press the
button located next to the lamp.
The lamps are xed and cannot be adjusted.
Electric Power 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 put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or 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.
