CHEVROLET CORVETTE 2004 5.G Owners Manual

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 finished, the lever will
return automatically.
An arrow on the instrument
panel cluster will flash 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 flash. 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 flash 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 do not go on at all when you
signal a turn, check the fuses and check for burned-out
bulbs. SeeFuses and Circuit Breakers on page 5-93.
Turn Signal on Chime
A chime will remind you if you leave the turn signal on
for more than 3/4 mile (1.2 km) of driving.
If you need to leave the turn signal on for more than
3/4 mile (1.2 km), turn off the signal and then turn it
back on.
3-7

Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, push the turn signal lever all the way forward.
While the high beams are
on, this light on the
instrument panel cluster
also will be on. To change
the headlamps from
high to low, pull the lever
rearward.
Headlamps on Reminder
If you turn the ignition off and leave the headlamps or
parking lamps on and open a door, you will hear a chime
reminding you to turn off the lamps.
Flash-to-Pass
To use the flash-to-pass feature, momentarily pull the
turn signal lever toward you. The high-beam indicator
will flash to indicate to the other driver that you intend to
pass. If the low-beam headlamps are off and you
have the optional fog lamps on, the fog lamps will flash.
Windshield Wipers
Use this lever located on the right side of the steering
column to operate the windshield wipers.
OFF:Move the lever to OFF to turn off the
windshield wipers.
INT (Intermittent):Move the lever to INT to choose a
delayed wiping cycle. Turn the INT ADJ band down
for a longer delay or up for a shorter delay. The further
the INT ADJ band is turned upward, the shorter the
delay will be and the further the INT ADJ band is turned
downward, the longer the delay will be.
3-8

The wiper speed can only be adjusted when the lever
is in the INT position. Use this position for light rain
or snow.
LO (Low Speed):Move the lever up to the first setting
past INT, for steady wiping at low speed.
HI (High Speed):Move the lever up to the second
setting past INT, for steady wiping at high speed.
MIST:Move the lever all the way down to MIST for a
single wiping cycle. Hold it there until the windshield
wipers start; then let go. The windshield wipers will stop
after one wipe. If you want more wipes, hold the
band on MIST longer.
Heavy snow or ice can overload the wipers. If this
occurs, a circuit breaker will stop the wipers until the
motor cools. So, be sure to clear any ice and snow from
the windshield wiper blades before using them. If the
wiper blades are frozen to the windshield, carefully
loosen them or warm the windshield before turning the
wipers on. If your blades do become worn or
damaged, get new blades or blade inserts.Windshield Washer
The lever on the right side of the steering column also
controls the windshield washer. There is a button at
the end of the lever. To spray washer fluid on the
windshield, press the button and hold it. The washer will
spray until you release the button. The wipers will
continue to clear the window for about six seconds after
the button is released and then stop or return to your
preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
If the fluid in the windshield washer fluid reservoir is low,
the message LOW WASHER FLUID will appear on the
Driver Information Center (DIC) display. It will take
60 seconds after the bottle is refilled for this message to
turn off. For information on the correct washer fluid to
use, seeWindshield Washer Fluid on page 5-36and
Recommended Fluids and Lubricants on page 6-11.

Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
When using cruise control, the accelerator pedal will
return to its fully-released position and will not
move while cruise control is engaged.
The Driver Information Center (DIC) will display the
cruise set speed in a digital number. For example, the
DIC will say CRUISE SET 60 mph (97 km/h).The cruise set speed and the speedometer indicated
speed may not always be exactly the same. When you
apply the brakes or push the clutch pedal, the cruise
control disengages. The DIC will show CRUISE
DISENGAGED. SeeDIC Warnings and Messages on
page 3-58.
{CAUTION:
Cruise control can be dangerous where you
can not drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.
If your vehicle is in cruise control when the Traction
Control System begins to limit wheel spin, the cruise
control will automatically disengage. SeeTraction
Control System (TCS) on page 4-9. When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
3-10

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press the SET button at the end of the lever and
release it. The cruise set speed will be displayed
by the Driver Information Center (DIC).
4. Take your foot off the accelerator pedal. The pedal
will return to an idle position.
Resuming a Set Speed
Suppose you set the cruise control at a desired speed
and then you apply the brake or clutch pedal. This,
of course, disengages the cruise control. But you do not
need to reset it.
Once you are going about 25 mph (40 km/h) or more,
you can move the cruise control switch to R/A
(Resume/Accelerate) briefly. The Driver Information
Center (DIC) will display the cruise set speed.
You will go right back up to your chosen speed and
stay there.
3-11

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
•Use the accelerator pedal to get to the higher
speed. The speed will not begin to increase
until sufficient pedal travel is achieved. Press the
SET button at the end of the lever, then release the
button and the accelerator pedal. You will now
cruise at the higher speed.
•Move the cruise switch to R/A. Hold it there until
you get up to the speed you want, then release
the switch. (To increase your speed in very small
amounts, move the switch to R/A briefly, then
release it. Each time you do this, the vehicle will go
about 1 mph (1.6 km/h) faster.)
The Driver Information Center (DIC) will display the
cruise set speed.
Reducing Speed While Using Cruise
Control
There are two ways to reduce speed while using cruise
control:
•Press in the SET button at the end of the lever
until you reach the lower speed you want, then
release it.
•To slow down in very small amounts, press the
SET button briefly. Each time you do this, you
will go about 1 mph (1.6 km/h) slower.
The Driver Information Center (DIC) will display the
cruise set speed.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase speed. When you
take your foot off the pedal, the vehicle will slow
down to the cruise control speed you set earlier.
3-12

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:
OFF:Turn the switch to this position to turn off all
lamps, except the Daytime Running Lamps (DRL).
;(Parking Lamps):Turn the switch to this position
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.
3-13

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.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:If the hood comes into contact with the
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.
3-15

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.
