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. 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. SeeInstrument
Panel Brightness on page 3-20.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.

reduction in performance, proceed to your destination.
The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a
reduced speed while this message is on, but
acceleration and speed may be reduced. Anytime this
