Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that
"Daytime Running Lights" (DRL) are a useful feature,
in that DRL can make your vehicle more visible to
pedestrians and other drivers during daylight hours.
DRL are required on new vehicles sold in Canada.
Your DRL works with a light sensor on top of the
instrument panel. Don't cover it up.
The low beam headlights will come on at reduced
brightness in daylight when:
The ignition is on,
0
The headlight switch is off and,
0
The transaxle is not in "P" (Park).
At dusk, if the Twilight Sentinel feature is turned on, the
exterior lights will come on automatically and the low
beams will change to full brightness. At dawn, the
exterior lights will go out and the low beams will
change to the reduced brightness of DRL (if the
headlight switch is off).
Of course, you may still turn on the headlights any time
you need to.
To idle your vehicle with the DRL off, shift the
transaxle into
" P '
(Park). The DRL will stay off until
you shift out of
" P '
(Park).
To turn off all exterior lighting at night when you are
parked, move the twilight sentinel control from ON to
OFF, if it was on from the start. Or, move the control
from OFF to ON, then back to OFF, if it was off from
the start. The lights will come back on when you move
the transaxle out of PARK.
