The DRL system will come on when the following
conditions are met:
·The ignition is on,
·the exterior lamps control is in AUTO,
·the transmission is not in PARK (P), and
·the light sensor determines it is daytime.
When the DRL are on, only your DRL lamps will be on.

on. The instrument panel won't be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

when it is dark out. The puddle lamps will illuminate
when a door is opened or when you press the unlock
button on the keyless entry transmitter. The lamps
will time out or turn off once the engine is started.
You can program the puddle lamps not to come on if
you choose. See

headlamps or parking lamps are on. Press the button
again to turn them off. An indicator light will glow
near the button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on the headlamps.
The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
