Front Reading Lamps

The reading lamps are located on the overhead console.
To turn the reading lamps on or off, press the button
located next to each lamp.
The lamps can be adjusted to a desired direction.
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. These lamps are fixed 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 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.
