Cadillac 2008 DTS, Owner'S Manual

Page: 174 / 450

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 3-35.
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.
To idle the vehicle with the DRL off at night, turn off
automatic lighting and shift the transmission into
PARK (P). Placing the vehicle in PARK (P) disables
the DRL. The DRL will stay off until the vehicle is shifted
out of PARK (P).
To drive the vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or fog
lamps, if the vehicle has them.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
- (Fog Lamps): The fog lamps button is located on
the exterior lamps control. The exterior lamps control
is located on the instrument panel to the left of the
steering column.
The ignition must be on for the fog lamps to work.
Press the exterior lamps button to turn the fog lamps
on or off. A light will come on in the instrument
panel cluster when the fog lamps are in use.
When the headlamps are changed to high-beam,
the fog lamps will turn off. The fog lamps come back on
again when the high-beam headlamps are turned off.
Some localities have laws that require the headlamps
to be on along with the fog lamps.
