Buick 2009 Enclave - Manual (Page 134)

Delayed Exit Lighting
This feature illuminates the interior
for a period of time after the key
is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the
key is removed, interior illumination
activates and remains on until
one of the following occurs:
• The ignition is in ON/RUN.
• The power door locks are
activated.
• An illumination period of
20 seconds has elapsed.
If during the illumination period
a door is opened, the timed
illumination period will be canceled
and the interior lamps will remain
on because a door is open.
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.
Reading Lamps
The vehicle has reading lamps that
also act as the dome lamp. Press
the button to turn them on and 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 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.
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.
