Exit Lighting; Battery Load Management - Cadillac 2015 Escalade Owner's Manual

Exit Lighting

Some exterior lamps and interior
lamps come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off and the indicator lever is
pulled briefly toward you and
released. The exterior lamps and
interior lamps remain on after the
door is closed for a set amount of
time, then automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalisation on
page 5-45.
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. The voltmeter
gauge or the voltage display on the
Driver Information Centre (DIC),
if equipped, may show the voltage
moving up or down. This is normal.
If there is a problem, an alert will be
displayed.
Lighting
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.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
