When it’s dark enough outside, your headlamps will
change to full brightness. The other lamps that come on
with your headlamps will also come on.
When it’s bright enough outside, the regular lamps will
go out, and your low
-
beam headlamps change to the
reduced brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
your vehicle. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
The fog lamps switch is located in the upper hand corner
of the instrument panel, to the left of the instrument
panel cluster.
To turn the fog lamps on, press the right side of the fog
lamps switch. A light will glow on the switch to let you
know that they are on. (The parking lamps must be on,
or the fog lamps won’t come on.) Press the left
-
hand
side of the switch to turn the fog lamps off.
