LIGHTING
129
This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
To flash the main beams, pull the
indicator stalk toward you, and
release.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day.
The dedicated DRL will come on when
all of the following conditions are met:
.
The ignition is on.
.
The exterior lamp control is
in AUTO.
.
The light sensor determines it is
daytime.
When the DRL are on, the tail lights
and other lamps will not be on.
The DRL lights are switched off when
the exterior lamp control is moved to
the PARK or HEADLIGHT position or
the ignition is switched off. The DRL
lights are not switched off in the OFF
position.
Automatic Headlamp
System
When the exterior lamp control is set
to AUTO and it is dark enough
outside, the headlights come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlight system
changes to the Daytime Running
Lamps (DRL). During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control is
in the full bright position. See
Instrument Panel Illumination Control
When it is bright enough outside, the
headlights will turn off or may change
to DRL.
The automatic headlamp system turns
off when the exterior lamp control is
turned to
O
or the ignition is off.
