lights will come on when all of the
following conditions are met:
.

.

in AUTO
.
The light sensor determines it is
daytime.
When the DRL are on, the
low-beam headlamps will be on.
The taillamps, sidemarker,
instrument panel lights and other
lamps will not be on.
The DRL turn off when the
headlamps are turned to
O or the
ignition is off.
