Reading Lamps; Footwell Lamps; Battery Load Management - Cadillac 2010 DTS Owner's Manual

Reading Lamps

The reading lamps are located on the overhead console
on the headliner and in the rear door opening. These
lamps come on automatically when any door is opened
and it is dark outside.
For manual operation, press the button to turn them on.
Press it again to turn them off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.

Footwell Lamps

For vehicles with footwell lamps, they are located under
the instrument panel and at the rear of the front
seats. These lamps provide soft light to the front and
rear floor areas. They dim with the instrument panel
cluster lights.
Footwell lighting brightness can be adjusted with the
instrument panel brightness control located below
the exterior lamps control. See Instrument Panel
Brightness on page 4-31. The footwell lights will turn off
before the instrument panel lights are at their lowest
level of brightness.

Battery Load Management

This feature monitors the vehicle's electrical load and
determines when the battery is in a heavy discharge
condition. During times of high electrical loading,
the engine may idle at a higher revolutions per minute
(rpm) setting than normal to make sure the battery
charges. High electrical loads may occur when several
of the following are on: headlamps, high beams, fog
lamps, rear window defogger, the climate control fan at
high speeds, heated seats and engine cooling fans.
If the battery continues to discharge, even with
the engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the climate control fan may cut
back to a lower speed. For more battery saving
information, see "Battery Saver Active Message" under
DIC Warnings and Messages on page 4-67.
