by pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to ON/RUN or
activating the power door locks.

Delayed Entry Lighting

The interior lamps will turn on if you open the door
when it is dark enough outside. When you close the
door with the ignition off, the interior lamps will stay on
for up to 25 seconds or until the ignition is turned to an
on position. When the lamps turn off as a result of the
25 second timer or the ignition switch being turned on,
the lighting will deactivate by way of the theater
dimming effect. Locking the doors will override the
delayed entry lighting feature and the lamps will turn off
right away.

Theater Dimming

This feature allows for a three to five second fade out of
the courtesy lamps instead of immediate turn off.

Delayed Exit Lighting

If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and stay
on for about 25 seconds. This will give you time to find
the door pull handle or lock switches. Once the key is
inserted into the ignition, the exit lighting will be
cancelled and the lighting will fade out.

Perimeter Lighting

If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.
This feature can be programmed on for various
amounts of time in seconds for each transmitter.
See DIC Vehicle Customization on page 4 56 for
information on programming.

Front Reading Lamps

The front reading lamps are located on the headliner.
Press the button near each lamp to turn them on or off.

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 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.
