2005 CHEVROLET VENTURE lock

A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered. The DRL
system will make front parking and turn signal lamps
come on in daylight when the following conditions
are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
When the DRL are on, only your front parking and turn
signal lamps will be on. Your instrument panel will
not be lit up.
When it is dark enough outside, the exterior lamps will
come on automatically. When it is bright enough
outside, the exterior lamps will turn off and the DRL will
turn on. Of course, you may still turn on the headlamps
any time you need to.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-15.To idle your vehicle with the DRL and automatic
headlamps off, set the parking brake while the ignition is
in OFF or LOCK. Then start the vehicle. The DRL
and automatic headlamps 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.Instrument Panel Brightness

turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity,
or moisture, condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or
frost from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs air to the windshield
and the oor outlets. When you select this mode,
the system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.
3-25

0(Defrost):Pressing this button directs most of the
air to the windshield and the side window outlets,
with some air directed to the oor outlets. In this mode,
the system will automatically turn off recirculation
and run the air-conditioning compressor, unless the
outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.
Do not drive the vehicle until all the windows are clear.
