2003 CHEVROLET CORVETTE headlamp

Engine Coolant Heater
(Canada Only)
The engine coolant heater is located on the driver's side
of the engine under the manifold.
In very cold weather, 0ÉF (-18ÉC) or colder, the engine
coolant heater can help. You'll get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle. At
temperatures above 32ÉF (0ÉC), use of the coolant
heater is not required.
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 ¯uid 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
won't reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.

Mirrors
Manual Rearview Mirror
An inside rearview mirror is attached above the
windshield. The mirror pivots so that you can adjust it.
You can adjust the mirror for day or night driving.
Pull the tab for night driving to reduce glare. Push the
tab forward for daytime driving.
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 ¯ood
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. To adjust
either mirror, press the LT (left) or RT (right) button
to select the mirror, then press the arrows to adjust the
direction of the mirror. The mirror will stay selected
for 20 seconds after the last adjustment. An indicator
light will come on above the mirror that you select.
Your preferred mirror position can be stored if you have
the memory option. See
Memory on page 2-55.
For operation of the heated outside mirrors, see
Dual
Automatic Climate Control System on page 3-22.
Outside Automatic Dimming Mirror
If your vehicle has this feature, the driver's side
outside mirror will adjust for the glare of headlamps
behind you. This feature is controlled by the on and off
setting on the inside mirror. See
Automatic Dimming
Rearview Mirror on page 2-37.
Outside Convex Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
·Turn and Lane-Change Signals
·Headlamp High/Low-Beam Changer
·Flash-to-Pass Feature
·Cruise Control
For information on exterior lamps, see
Exterior Lamps
on page 3-12.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the multifunction lever all the
way up or down. When the turn is ®nished, the lever will
return automatically.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If you signal a turn or a lane change and the arrows
¯ash faster than normal, a signal bulb may be burned out.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check the fuses and check for burned-out
bulbs. See
Fuses and Circuit Breakers on page 5-86.

Headlamps Doors
The headlamp doors are designed to open when you
turn the headlamps on, and close when you turn
the headlamps and parking lamps off. If you turn the
headlamps on, then turn back to the parking lamps
setting, the headlamp doors will stay open.
3-12

You can open the doors manually using the knob next
to the headlamp assembly. Turn the knob
counterclockwise until the doors are open. Turn the
knob clockwise to close the doors manually.
The headlamp doors should be open when driving in icy
or snowy conditions to prevent the doors from freezing
closed and when washing the vehicle to help clean
the headlamps.
Notice:In order to avoid possible contact of the
hood to the headlamp doors, either take care
in raising the hood with the headlamps up, or turn
off the headlamps prior to opening the hood.
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.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 won't be on. Your instrument panel
won't 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.
3-13

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 won't 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 when the fog lamps
are on. Press the button again to turn the fog lamps off.
Twilight Sentinelž(Optional in United
States, Standard in Canada)
Twilight Sentinelžcan turn your lamps on and off for
you. A light sensor on top of the instrument panel makes
the Twilight Sentinel
žwork, so be sure it isn't covered.
You can customize your vehicle to turn Twilight
Sentinel
žon or off (except for vehicles ®rst sold in
Canada). SeeDriver Information Center (DIC) on
page 3-44to turn this feature on or off.
When Twilight Sentinel
žis turned on, you will see the
following happen:
·When it's 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's 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 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.
