Front Reading Lamps

There may also be a reading lamp in the
second row, integrated with the dome lamp.
To turn the second row reading lamp on or off,

Cargo Lamp
The cargo lamp is located in the rear of your
vehicle, above the liftgate opening, and does not
have a switch. The cargo lamp will come on
each time you open a door, unless you turn on the
interior lamps override. See Interior Lamps
Control on page 184.
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, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
