Lighting
Flash-to-Pass
The flash-to-pass feature works with
the low beams or Daytime Running
Lamps (DRL) on or off.
To flash the high beams, pull the
turn signal lever all the way toward
you, then release it.
Daytime Running
Lamps (DRL)
The DRL system makes the
low-beam headlamps come on at a
reduced brightness in daylight when
the following conditions are met:
.
The ignition is on.
.
The exterior lamp control is
in AUTO.
.
The transmission is not in
P (Park).
.
The light sensor determines it is
daytime.
.
The parking brake is released.
Fully functional DRL are required on
all vehicles first sold in Canada.
When the DRL are on the taillamps,
sidemarker, instrument panel lights
and other lamps will not be on. The
instrument cluster will be lit.
When the exterior lamp control is
turned to
5
, the low-beam
headlamps come on. The other
lamps that come on with the
headlamps will also come on.
To idle your vehicle with the DRL
off, move the shift lever to P (Park).
The DRL will stay off until the shift
lever is moved out of the P (Park)
position.
The regular headlamp system
should be turned on when needed.
Automatic Headlamp
System
When it is dark enough outside, the
headlamps come on automatically.
Do not cover the light sensor on top
of the instrument panel or the
headlamps will come on when they
are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
