Exit Lighting; Parade Dimming; Battery Load Management - Cadillac CTS 2013 Owner's Manual

Exit Lighting

The headlamps, tail lamps, parking
lamps, reversing lamps, and number
plate lamps come on at night, or in
areas with limited lighting, when the
key is removed from the ignition.
The dome lights also come on when
the key is removed from the ignition.
The exterior lights and dome lamps
remain on after the door is closed
for a set amount of time, then
automatically turn off.
For vehicles with keyless access,
the exterior lamps and dome lamps
automatically turn on when a door is
opened after the ignition is turned
off. See Ignition Positions (Key
Access) on page 9 12 or Ignition
Positions (Keyless Access) on
page 9 14.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalisation on
page 5 47.

Parade Dimming

This feature does not let the
instrument panel display screens
dim during daylight hours while the
ignition is in the ACC/ACCESSORY
or ON/RUN position and the parking
lamps or headlamps are on. Parade
dimming automatically works with
the light sensor on top of the
dashboard. If it is dark enough
outside and the parking lamps or
headlamps are on, the instrument
panel display screens can be
adjusted by turning the instrument
panel brightness knob clockwise or
anticlockwise to brighten or dim the
lighting. See Instrument Panel
Illumination Control on page 6 6.
The instrument panel control
backlighting can still be adjusted
while in parade mode.

Battery Load
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
Centre (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
