GMC 1998 Jimmy - Daytime Running Lamps; Fog Lamps (if Equipped)

Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful
in the
short periods after dawn and before sunset.
The DRL system will make your headlamps come on at
reduced brightness when:
the ignition is on,
the headlamp switch is in automatic headlamp
mode and
the parking brake is released.
When the DRL are on,
only your headlamps will be on.
The taillamps, sidemarker and other lamps
won’t be on.
The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
When
you turn the headlamp switch off, the regular lamps
will
go off, and your headlamps will change to the reduced
brightness of
DRL provided it is not dark outside.
To idle your vehicle with the DRL off, set the parking
brake. 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 (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps must be on for your fog
lamps
to work.
The fog lamp switch is on the instrument panel under
the lamps switch. Press the switch to turn the fog lamps
on. Press the switch again to turn them off. A light will
glow in the switch when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps in
the dark without turning on your headlamps.
Fog lamps will go off whenever your high-beam
headlamps come
on. When the high beams go off, the
fog lamps will come
on again.
