2003 CHEVROLET SILVERADO manual radio set

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 located 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.
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
bright enough outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make sureyour instrument panel brightness control is in the full
bright position. See ªInstrument Panel Brightness
Controlº underInterior Lamps on page 3-18.
To idle your vehicle with the automatic headlamp system
off, turn the control to the off position.
You may be able to turn off your automatic headlamp
system. See
Daytime Running Lamps (DRL)later in this
section for more information.
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 them.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your
ignition is off, in LOCK, ACCESSORY, or your door is
open. To disable the chime, turn the light off then
back on.
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
lamps are required on all vehicles ®rst sold in Canada.

Notice:If the other system isn't a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. If you have a vehicle with a diesel engine with two
batteries (or more), you should know before you
begin that, especially in cold weather, you may not
be able to get enough power from a single
battery in another vehicle to start your diesel engine.
If your vehicle has more than one battery, use
the battery that's closer to the starter ± this
will reduce electrical resistance.
3. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake ®rmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake. If
you have a four-wheel-drive vehicle, be sure
the transfer case is in a drive gear not in NEUTRAL.Notice:If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn off the
radio and all lamps that aren't needed. This
will avoid sparks and help save both batteries. And
it could save your radio!
5. Open the hoods and locate the positive (+) and
negative (-) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (-) jump
starting terminal. You should always use these
remote terminals instead of the terminals on the
battery.
The remote positive (+) terminal is located behind a
red plastic cover near the engine accessory drive
bracket. To uncover the remote positive (+) terminal,
open the red plastic cover.
The remote negative (-) terminal is located on the
engine drive bracket on all V8 and diesel engines,
and on the thermostat housing on the 8.1L engine.
On V8 engines it is marked ªGND.²
