2004 CHEVROLET CORVETTE cruise control

Telescopic Steering Column
If your vehicle has this feature, the telescopic steering
column will allow you to adjust the distance the steering
wheel is from the instrument panel.
The telescopic steering
column switch is located
on the right side of
the steering column.
To operate the telescopic steering column, push the
switch forward and the wheel will move away from you.
Pull the switch rearward and the wheel will move
toward you.
The telescopic steering column position can be stored
with your memory settings. SeeMemory on page 2-57
for more information.
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, seeExterior Lamps
on page 3-13.

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.

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.

Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
Your vehicle has a traction control system called TCS
that limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark) to
limit wheel spin.
The TRACTION SYS ACTIVE message will come on
when the TCS system is limiting wheel spin. See
DIC Warnings and Messages on page 3-58. You may
feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the TCS system
begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions allow you
to safely use it again, you may re-engage the cruise
control. SeeTurn Signal/Multifunction Lever on page 3-6.
