Entry/Exit Lighting

The lamps inside the vehicle will go on when any door
is opened. These lamps fade out about 20 seconds
after all of the doors have been closed or when
the ignition is turned to ON/RUN. These lamps will also
go on when pressing the trunk release, unlock symbol,
or the horn symbol button on the Remote Keyless Entry
System (RKE) Transmitter.
After the key is removed from the ignition, the lamps
inside the vehicle stay on for about 20 seconds to
provide an illuminated exit.

Mirror Reading Lamps

Your vehicle may have reading lamps on the rearview
mirror. Push the button to turn the reading lamps on
and off.

Electric Power Management

This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery's
temperature and state of charge and 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.
