headlamp CHEVROLET CORVETTE 2004 5.G Owners Manual

To Use The Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is attached to the generator
bracket assembly, between the generator and the
windshield washer fluid tank. With the headlamps
closed, route the cord in the opening between
the headlamp door and the fender panel on
the driver’s side of the vehicle. Do not pinch the
cord when closing the hood.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Automatic Dimming Rearview Mirror
Your vehicle may have an automatic dimming rearview
mirror with map lamps.
This mirror automatically changes to reduce glare from
headlamps behind you. A time delay feature prevents
rapid changing from the day to night positions while
driving under lights and through traffic.
The mirror includes two map lamps and an automatic
dimming function. There is also an interior console flood
lamp located underneath the rearview mirror which
remains on at all times.IO (On/Off):The automatic dimming feature is turned
on or off by pressing this button located on the
lower part of the mirror. Press and hold the button for
up to three seconds to turn this feature on or off.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror housing.
Outside Power Heated Mirrors
The power mirror control is on the driver’s door. It
controls the driver’s and passenger’s mirrors.

could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going downhill, you may have to brake or
shift to a lower gear to keep your speed down. Of
course, applying the brake takes you out of cruise
control. Many drivers find this to be too much trouble
and do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
•Step lightly on the brake pedal or push the clutch
pedal, if you have a manual transmission vehicle.
•Move the cruise switch to OFF.
The Driver Information Center (DIC) will display the
message CRUISE DISENGAGED.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
cruise control set speed memory is erased.
Exterior Lamps
The exterior lamp switch on the turn signal/multifunction
lever operates the headlamps.
The exterior lamp switch has three positions:

to turn on the parking lamps, together with the
following:
•Taillamps
•Parking Lamps
•Sidemarker Lamps
3(Headlamps):Turn the switch to this position to
turn on the headlamps, together with the previously
listed lamps.

headlamp doors when you raise the hood, you could
damage the hood and/or the headlamp doors.
Always close the headlamp doors before opening
the hood.
3-14

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
first sold in Canada.
The DRL system will make the front turn signal lamps
come on when the following conditions are met:
•The ignition is on,
•the exterior lamp switch is off and
•the parking brake is released.
When the DRL are on, only the front turn signal lamps
will be on. The headlamps, taillamps, sidemarker
and other lamps will not be on. Your instrument panel
will not be lit up either.
To idle the vehicle with the DRL off, set the parking
brake while the ignition is in OFF. Then start the vehicle.
The DRL, headlamps and parking lamps 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
Your vehicle may have this feature. Use the fog lamps
for better vision in foggy or misty conditions. Your
parking lamps or low-beam headlamps must be on or
the fog lamps will not work.
To turn the fog lamps on, press the button located on
the instrument panel, to the left of the steering column. A
light in the button will come on while the fog lamps
are on. Press the button again to turn the fog lamps off.

Twilight Sentinel®(Optional in United
States, Standard in Canada)
Twilight Sentinel®can turn your lamps on and off for
you. A light sensor on top of the instrument panel makes
the Twilight Sentinel
®work, so be sure it is not covered.
You can customize your vehicle to turn Twilight
Sentinel
®on or off, except for vehicles first sold in
Canada. SeeDriver Information Center (DIC) on
page 3-48to turn this feature on or off.
When Twilight Sentinel
®is turned on, you will see the
following happen:
•When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
•When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the OFF position.
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 about 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
full bright position. See “Instrument Panel Brightness
Control” underInterior Lamps on page 3-17.
With Twilight Sentinel
®turned on, you can idle the
vehicle with the lamps off, even when it is dark outside.
First set the parking brake while the ignition is in
OFF. Then start the vehicle. The lamps will stay off until
you release the parking brake.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
•The exterior lamp switch is moved from OFF to the
parking lamp position, or
•a delay time that you select has elapsed.
SeeDriver Information Center (DIC) on page 3-48to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
