Wiper Activated Headlamps; Headlamps On Reminder; Daytime Running Lamps (Drl) - Cadillac 2010 DTS Owner's Manual

Wiper Activated Headlamps

This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off. The
wiper-activated headlamps also turn off if the windshield
wipers are turned off.

Headlamps on Reminder

A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.

Daytime Running Lamps (DRL)

Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. Fully functional daytime running lamps are required
on all vehicles first sold in Canada.
The DRL system makes the turn signal lamps come on
when the following conditions are met:
•
It is still daylight and the ignition is on.
•
The exterior lamp control is in the off position.
•
The transmission is not in P (Park)
(United States only).
•
The light sensor is covered or not detecting light.
See "Sensors" under Dual Climate Control System
on page 4-36.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the
DRL are being used. The instrument panel will not be lit
up either.
When automatic lighting is on and it is dark enough
outside, the turn signal lamps turn off and normal
low-beam headlamp operation occurs.
When automatic lighting is on and it is bright enough
outside, the regular lamps go off, and the DRL
takes over. If the vehicle is started in a dark garage, the
automatic headlamp system comes on immediately.
Once you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if there is light outside. During that delay,
the instrument panel cluster may not be as bright as
usual. Make sure the instrument panel brightness knob
is in the full bright position. See Instrument Panel
Brightness on page 4-31.
Turning on automatic lighting or the headlamps will
deactivate the DRL. If the parking lamps or the
fog lamps were turned on instead, the DRL will still
deactivate.
