I believe that your 2003 and my 2004 are substantially the same when it
comes to this. Unfortunately, the owner's manual does not list anything
about setting your headlights (not your daytime running lights) to come on
automatically when you start the truck unless it is dark outside and you
have automatic headlights. However, there are two ways for you to do this
First, if your truck has automatic headlights (the type that come on when
it's dark outside without you flipping the switch) then all you need to do
is take a small piece of either duct tape or dash carpeting and place it
over the sensor on top of the dash, which is usually located either around
or inside one of the defroster vents. Covering the sensor makes the truck
think it's dark outside and automatically turn on the headlights. That is
the easiest and simplest way to do this.
The second involves a little sarcasm on my part... Just turn on the switch
for the headlights! Is it really that hard? Sorry, I couldn't resist...
