2004 CHEVROLET CORVETTE Owners Manual

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.

Interior Lamps
Instrument Panel Brightness
The knob for this feature is
located on the left side of
the instrument panel.
Push the knob to release it from the stored position.
Turn the knob clockwise to brighten the lights or
counterclockwise to dim them.
Be sure not to have this knob turned all the way down
with the lamps on during the day. Your Driver
Information Center (DIC) may not be visible.
Parade Mode
The instrument panel brightness knob has an added
feature called parade mode to assist you in seeing
certain instrument panel controls if your headlamps are
on in the daylight. Turn the knob counterclockwise to
dim the instrument panel lights or clockwise to brighten
the lights. This will occur only with the parking lamps
or headlamps on.
Courtesy Lamps
When any door or the hatch/trunk lid is opened, the
interior lamps will go on unless it is bright outside.
You can also turn on the courtesy lamps by turning the
instrument panel brightness knob all the way clockwise.
Exit/Entry Lighting
With entry lighting, the interior lamps will come on when
entering the vehicle. The interior lamps will come on
for about 20 seconds when the key is turned to OFF or
a door is ajar.
You can turn exit and entry lighting off by quickly turning
the headlamps on and off or by quickly turning the
courtesy lamps on and off.
3-17

Reading Lamps
Your inside rearview mirror includes two reading lamps.
The lamps will go on when a door is opened. When
the doors are closed, each lamp can be turned on
individually by pressing the switch for that lamp.
There is also an interior console flood lamp located
underneath the rearview mirror which comes on during
nighttime operation or when the reading lamps are on.
Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console or
glove box lamps are accidentally left on. If you leave any
of these lamps on, they will automatically timeout after
about 15 minutes. To reset it, all of the above lamps must
be turned off or the ignition key must be in ON.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.
3-18

The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. The HUD consists of the
following information:
•Speedometer
•Turn Signal Indicators
•High-Beam Indicator Symbol
•Tachometer
•Oil, Temperature and Fuel Gages
•Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle’s best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine speed
of about 5,750 rpm (6,250 rpm on Z06), just prior to
reaching the engine fuel cut-off mode.
•Check Gages IconThere are five HUD selections that you can choose to
view in the HUD display. By pressing and holding
the PAGE button, you can scroll through these pages in
the following order:
•Speed Only
•Speed and Gage
•Speed, Tachometer and Gage
•Speed and Tachometer
•Tachometer Only
When you have chosen the desired HUD display,
release the PAGE button.
Gages can be scrolled through by tapping the PAGE
button (only when a gage is displayed). The gages
shown are the following:
•Oil Pressure
•Coolant Temperature
•Fuel Level
The selections that you choose will remain in the HUD
display until they are changed.
3-19

Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES icon will illuminate in
the HUD. View your Driver Information Center (DIC) for
more information.The HUD controls are located to the left of the
steering wheel.
To adjust the HUD so you can see it properly, do the
following:
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
the light conditions in the direction your vehicle is
facing and where you have the HUD dimmer control
set. If you are facing a dark object or a heavily
shaded area, your HUD may anticipate that you are
entering a dark area and may begin to dim.
3-20

It is possible for sunlight to enter the HUD causing
all of the graphics to light up. The display will
return to normal when the sunlight is no longer
entering the HUD.
2. Adjust the seat to a comfortable driving position. If
you change your seat position later, you may have
to re-adjust your HUD.
3. Press the top or bottom of the DISPLAY switch to
center the HUD image in your view.
The HUD image can only be adjusted up and down,
not side-to-side.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary.
To turn HUD off, slide the switch to OFF.
If the sun comes out or it becomes cloudy, you may
need to adjust the HUD brightness again using
the dimmer control. Polarized sunglasses could make
the HUD image harder to see.
To change from English to metric units, press the
E/M button located to the right of the steering wheel.Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.
If the ignition is on and you can’t see the HUD image,
check to see if:
•Something is covering the HUD unit.
•The HUD dimmer control is adjusted properly.
•The HUD image is adjusted to the proper height.
•Ambient light, in the direction your vehicle is facing,
is low.
•A fuse is blown. SeeFuses and Circuit Breakers on
page 5-93.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred and out of focus.
