2008 CHEVROLET CORVETTE cruise control

The Manual Paddle Shift system will not allow either an
up-shift or a down-shift if the vehicle speed is too
fast or too slow, nor will it allow a start from Fourth (4)
or higher gear
If up-shifting does not occur when needed, the vehicle
speed will be limited to protect the engine.
The transmission will also automatically down-shift as
the vehicle slows down and comes to a stop.
When the transmission gear does not respond to a shift
change, the DIC will show an X over the gear display.
When a requested shift is
denied due to the speed
restrictions shown, the DIC
will momentarily show
an X over the gear display
and a chime will sound.
If the vehicle has a HUD, and the transmission gear
does not respond to a shift change, then a chime
will sound and the HUD will momentarily show an X
over the gear display.Manual Paddle Shift operation is available for use with
Cruise Control, seeCruise Control on page 3-11for
more information.
The vehicle speeds required for Manual Paddle Shift
up-shifts depend on several vehicle inputs, which
will vary the allowed up-shift speed by a few mph (km/h).
Up-shifts to Fourth (4) gear require approximately
22 mph (35 km/h).
Up-shifts to Fifth (5) gear require approximately
28 mph (45 km/h).
Up-shifts to Sixth (6) gear require approximately
41 mph (65 km/h).
To prevent damage to the powertrain, Manual Paddle
downshifts to a lower gear cannot be done above certain
speeds. The maximum speed allowed for downshifting
of gears one (1) through fourth (4) are:
Into Fourth (4) gear over 168 mph (270 km/h)
Into Third (3) gear over 124 mph (200 km/h)
Into Second (2) gear over 81 mph (130 km/h)
Into First (1) gear over 45 mph (72 km/h).
If the driver does not request an upshift as the engine
speed approaches fuel shut off RPM, the engine
speed will be limited to protect the engine. See
Tachometer on page 3-36for more information.

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 uid 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 uid in the windshield washer uid reservoir is
low, the message CHECK WASHER FLUID will appear
on the Driver Information Center (DIC) display. It will
take 15 seconds after the bottle is relled for this
message to turn off. For information on the correct
washer uid to use, seeWindshield Washer Fluid on
page 5-41andRecommended Fluids and Lubricants
on page 6-12.
Cruise Control
Your vehicle has cruise
control.
9(Off):Slide the switch to this position to turn the
system off.
R(On):Slide the switch to this position to turn the
system on.
+ (Resume/Accelerate):Slide the switch to this
position to make the vehicle accelerate or resume a
previously set speed.
T(Set):Press this button at the end of the lever to
set the speed.
3-11

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).
Cruise control will not work if your parking brake is set,
or if the master cylinder brake uid level is low.
{CAUTION:
Cruise control can be dangerous where you
cannot 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 excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
If your vehicle is in cruise control, and has the Traction
Control System (TCS), and it begins to limit wheel
spin, the cruise control automatically disengages.
SeeTraction Control System (TCS) on page 4-6.
When road conditions allow you to safely use it again,
you can turn 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 desired.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
When the cruise control is engaged, the CRUISE SET
TO XX MPH message displays on the Driver Information
Center (DIC). SeeOther Messages on page 3-74.
3-12

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. 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 briey from on to
resume/accelerate.
You will go right back up to your chosen speed and
stay there.
If you hold the switch at resume/accelerate the vehicle
keeps going faster until you release the switch or
apply the brake. Do not hold the switch at
resume/accelerate, unless you want the vehicle to go
faster.
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. 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.
If the accelerator pedal is held longer than
60 seconds, cruise control will turn off.
Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed desired, and then release the switch.
To increase your speed in very small amounts,
move the switch briey to resume/accelerate.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control

Press and hold the set button until you reach the
lower speed you want, then release it.
To slow down in very small amounts, briey press
the set button. Each time you do this, you will go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle
slows down to the cruise control speed you set earlier.
3-13

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 up steep hills, you might want to step
on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake
or shift to a lower gear to keep the vehicle’s speed
down. Of course, applying the brake turns off the cruise
control. Many drivers nd this to be too much trouble
and do not use cruise control on steep hills.
Cruise Control in Sport (S) and Manual
Paddle Shift Gear Selection
When your vehicle is in Sport (S) and the manual
paddle shift controls are not being used, cruise control
operates in the same manner as Drive (D).
When your vehicle is in Sport (S) and the manual
paddle shift controls are being used, cruise control
operates as follows:
If cruise control is active and a gear is selected
with the manual paddle shift controls, the vehicle
maintains vehicle speed in the driver selected gear
and will not automatically up-shift or down-shift
the transmission while the driver’s gear selection
is active.
If driving in hilly terrain, cruise control may not
be able to maintain vehicle speed if an up-shift
or down-shift is not selected by the driver.
While driving on hilly terrain and cruise control is
active with a manual paddle shift gear selection,
the driver must select the proper gear for the terrain
or select Drive (D) on the gear range selector for
full automatic transmission operation.
Ending Cruise Control
To end a cruise control session, step lightly on the
brake pedal. If your vehicle has a manual transmission,
lightly tapping the clutch will also end a cruise control
session.
Move the cruise control switch to off to turn the system
completely off.
When cruise control is disengaged, the CRUISE
DISENGAGED message displays on the Driver
Information Center (DIC). SeeDIC Warnings and
Messages on page 3-57.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.
