Daytime Running Lamps - Cadillac 2005 CTS Owner's Manual

Daytime Running Lamps

Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
•
It is still daylight and the ignition is in ON or START,
•
the exterior lamp control is in off or AUTO with the
headlamps off, and
•
an automatic transmission is not in PARK (P) or the
parking brake is not set on a manual transmission.
When DRL are on, only your front turn signal lamps
will be on. No other exterior lamps will be on when the
DRL are being used. Your instrument panel won't
be lit up either.
When the exterior lamp control is in AUTO and it's dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it's bright enough outside,
the low-beam headlamps will go off, and the DRL will turn
back on. If you start your vehicle in a dark garage, the
automatic headlamp system will come on immediately.
3-22
Once you leave the garage, it will take about one minute
for the automatic headlamp system to change to DRL if it
is light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness lever is in the full bright
position. See Instrument Panel Brightness on page 3-24 .
If it's dark enough outside and the exterior lamp control
is off, a Headlamps Suggested message will appear
on the Driver's Information Center (DIC) display.
This message informs the driver that turning on the
exterior lamps is recommended even though the DRL
are still illuminated. Turning the exterior lamp control to
AUTO or to the low-beam headlamp position will
turn off the DRL and cancel the Headlamps Suggested
message. If the parking lamps or the fog lamps were
turned on instead, the DRL will still turn off and the
Headlamps Suggested message will be displayed. You
can turn it off by pressing the OK button if you have
the Navigation audio system or the CLR button if
you have the Base audio system.
To operate your vehicle with the DRL off, turn the
exterior lamp control off. Then turn on the fog lamps
or parking lamps, and the DRL will turn off. The
Headlamps Suggested message will appear on the
DIC display. This will work regardless of gear position
and whether or not the parking brake is set.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
