Daytime Running Lamps
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 high-beam headlamps
come on at reduced brightness when the following
conditions are met:
•
It is still daylight and the ignition is on,
•
the exterior lamp control is in the off position and
•
the transaxle is not in PARK (P).
When DRL are on, only your high-beam headlamps (at
reduced brightness) will be on. No other exterior
lamps such as the parking lamps, taillamps, etc. will be
on when the DRL are being used. Your instrument
panel will not be lit up either.
When the Twilight Sentinel
®
lever is on and it is dark
enough outside, the high-beam headlamps (at reduced
intensity) will turn off and normal low-beam headlamp
operation will occur.
When the Twilight Sentinel
®
lever is on and it is bright
enough outside, the regular lamps will go off, and
the high-beam headlamps at reduced brightness will
take over. 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 approximately
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
knob is in the full bright position. See “Instrument Panel
Brightness” under Interior Lamps on page 3-22.
If it is dark enough outside and the Twilight Sentinel
®
lever is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are
still illuminated. Turning on the Twilight Sentinel
®
or the
headlamps will deactivate the DRL and remove the
HEADLAMPS SUGGESTED message. If the parking
lamps or the fog lamps were turned on instead, the DRL
will still deactivate and the HEADLAMPS SUGGESTED
message will continue to be displayed.
