Headlamps on Reminder
A warning chime will sound if the exterior lamp
control is left on in either the headlamp or parking
lamp position and the driver’s door is opened
with the ignition off. See
Lights On Reminder on
page 207 for additional information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles first sold in Canada.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
•
It is still daylight and the ignition is in ON or
START.
•
The exterior lamp control is in off or AUTO and
the headlamps are off.
•
The automatic transmission is not in PARK (P).
When DRL are on, only your front turn signal
lamps will be on. No other exterior lamps will be
on. Your instrument panel cluster will not be
lit up either.
When the exterior lamp control is in AUTO and it
is dark enough outside, the DRL will turn off
and the low-beam headlamps will turn on. When it
is 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.
See
Instrument Panel Brightness on page 176 .
