Daytime Running Lamps (DRL)
Indicator Light
This light is located on the
instrument panel cluster. It
goes on whenever the
Daytime Running Lamps
are on.
See “Daytime Running Lamps” in the Index.
When it begins to get dark, the DRL indicator light is a
reminder to turn on your headlamps.
Low Washer Fluid Warning Light
This light will come on
when your vehicle is low on
windshield washer fluid.
For more information, see “Windshield Washer Fluid” in
the Index.
Check Gages Indicator Light
This light will come on as
you’re starting the engine,
just as a check.
If it ever comes on and stays on while you are driving,
however, it means that either your engine coolant
temperature gage or your engine oil pressure gage may
be showing a reading in the warning zone.
When the check gages light comes on, you will also hear
a warning tone. The tone and the light will stay activated
until the problem is corrected.
This light may also come on if your vehicle is equipped
with the optional automatic engine shutdown system and
engine shutdown has begun. See “Engine Automatic
Shutdown” in the Index.
