132 LIGHTING
Entry Lighting with Approach
Detection
If equipped with approach detection,
the entry lighting feature will
automatically turn on when the

“Vehicle Locator Lights”under
Vehicle Personalization 0117.

(16 ft) range of the vehicle for
several minutes

The exit lighting for exterior lights can

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 enough at
idle to produce all the power that is
needed for very high electrical loads.
