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
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.
Lights On with Wipers
If the windscreen wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlights, parking lights, and other exterior
lamps come on. The transition time for the
lamps coming on varies based on wiper
speed. When the wipers are not operating,
these lamps turn off. Move the exterior
lamp control to
O
or
;
to disable this
feature.
