2001 CHEVROLET ASTRO ignition

2-42 Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel in the defroster grille. Be sure it
is not covered, or the system will be on whenever the
ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lights does
not affect the system. The DRL and automatic headlamp
system will only be affected when the light sensor sees a
change in lighting lasting longer than the delay.To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later in
this section for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on and your ignition is
in OFF, LOCK or ACCESSORY. To disable the tone, turn
the thumbwheel all the way down. In the automatic mode,
the headlamps turn off once the ignition key is in OFF.

2-43 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. Fully
functional daytime running lights are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come on at a
reduced brightness when the following conditions are met:

The ignition is on,

the headlamp switch is in automatic headlamp mode,

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the
last chosen headlamp setting that was used.To idle your vehicle with the DRL off, put the
transmission in PARK (P). The DRL will stay off until
you shift out of PARK (P).
The following does not apply to vehicles first sold in
Canada, and to some early production vehicles.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running
Lamps (DRL) feature by following the steps below:

Turn the ignition to RUN.

Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you that the
system is off.

To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(the chime will sound), or turn the ignition to
OFF and then to RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Interior Lamps
Instrument Panel Intensity Control
The instrument panel intensity control is located to the
right of the headlamp switch.
Move the thumbwheel up to adjust the instrument panel
lights. To turn on the dome lamps (with the vehicle
doors closed), move the thumbwheel all the way up.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lights will not
come on if the DOME OVERRIDE button is pressed in.
Illuminated Entry
Your vehicle is equipped with an illuminated entry feature.
When a door is opened, the dome lamps will come on if the
DOME OVERRIDE button is in the ªoutº position. When all
the doors are closed, the lamps will stay on for a short period
of time and will then go out. If the DOME OVERRIDE
button is pressed in, the lamps will not come on.
Dome Lamps
The dome lamps will come on when you open a door.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the parking/headlamps
knob, all the way up. In this position, the dome lamps
will remain on whether a door is opened or closed.
You can use the DOME OVERRIDE button, located
below the parking/headlamp knob, to set the dome
lamps to come on automatically when a door is opened,
or to remain off. To turn the lamps off, press the button
into the ªinº position, the dome lamps will remain off
when a door is open. To return the lamps to automatic
operation, press the button again and return it to the
ªoutº position. With the button in this position, the dome
lamps will come on when you open a door.

2-45 Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity, reading
and glove box lights if they are left on for more than
20 minutes when the ignition is off. This will keep your
battery from running down.
If the battery run
-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:

Shut off all lamps and close all doors, or

turn the ignition key to RUN.
Mirrors
Inside Day/Night Rearview Mirror
You can adjust the mirror for day or night driving.
Press the tab forward (away from you) for day driving.
Pull the tab back (toward you) for night driving.
Outside Manual Adjust Mirror
Adjust your outside mirrors so you can see a little of the
side of your vehicle.
You can fold them inward before entering a car wash.
Pull the mirrors toward the vehicle. Push the mirrors
back out when finished. After pushing the mirror out,
the adjustment will be maintained.

2-49 Overhead Console (Option)
The overhead console includes reading lamps, a
compartment for a garage door opener, a trip computer,
a temperature and compass display, and a storage
compartment for sunglasses.
The reading lamps, trip computer and temperature and
compass display will work when the ignition is in RUN,
ACCESSORY or when Retained Accessory Power (RAP)
is active. See ªRetained Accessory Powerº in the Index.Reading Lamps
Press the button near each
lamp to turn the reading
lamps on and off.
The lamps can also be swiveled to point in the direction
you want.

Driver Information System (If Equipped)
This system displays the outside air temperature, compass
direction and trip information in the overhead console.
US/MET: The US/MET (United States/metric) button
allows you to switch the display between the English
and metric system.
MODE: The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.COMP/TEMP: The display provides the outside
temperature and one of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move the vehicle, the
temperature indicated will be the last outside temperature
recorded with the ignition on. If the outside temperature is
37
F (3
C) or lower, the display will toggle between the
word ICE and the current temperature every eight seconds.
This is a warning to the driver that road conditions may be
icy, and that appropriate precautions should be taken.
The compass is self
-calibrating, so it does not need to be
manually set. However, if ªCº (Calibration) is displayed,
the compass will need to be calibrated. You may also place
the compass in a noncalibrated mode by pressing and
holding the MODE and US/MET buttons simultaneously
while in the COMP/TEMP mode. After about 10 seconds,
the compass will display C and you can release the
buttons. Drive the vehicle in a complete 360
circle
three times at a speed of less than 5 mph (8 km/h), and
the compass will function normally. Once the calibration is
complete, the display will return to a compass reading.
Variance is the difference between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to set
the variance for your particular location:

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn the ignition on, but
the engine is not running, as
a check to show you the
light is working.
Then it should go out once the engine is running.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose accessory drive
belt, or another electrical problem. Have it checked right
away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and heater/air conditioner.
