Delayed Exit Lighting
This feature illuminates the interior
for a period of time after the key is

Parade Dimming
Parade mode automatically prohibits
the dimming of the instrument panel
displays during the daylight while
the headlamps are on so that the
displays are still able to be seen.
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.
