: button before you can take your key
t of the ignition lock.
NOTICE:
If your key seems stuck in “Lock”
and you can’t turn it, be sure it is all
the way in. If it is, then turn the steer-
ing wheel left and right while you
turn the key hard. But turn the key
only with your hand. Using a tool to
force it could break the key or the
ignition switch. If none of this works,
then your vehicle needs service.
Delayed Accessory Bus (DAB)
With DAB your power windows and the
audio system will continue to work up to
15 minutes after the ignition key is turnec
to “Off’ and neither door is opened.
If a
door is opened, the audio system and
power windows will shut
off.
Starting Your Engine
Automatic Transmission: Move your
shift lever to
“P’ (Park) or “N” (Neutral).
Your engine won’t start in any other
position
- that’s a safety feature. To
restart when you’re already moving,
use
“N” (Neutral) only.
NOTICE:
Don’t try to shift to “P” (Park) if your
Corvette is moving. If you do, you
could damage the transmission. Shift
to
“P” (Park) only when your vehicle
is stopped.
ManuaI Transmission: The gear selector
should be
in neutral. Hold the clutch
pedal to the
floor and start the engine.
Your vehicle won’t start if the clutch
pedal is not all the way down
- that’s a
safety feature.
To start your 5.7 Liter LTl engine:
1. Without pushing the accelerator pedal
turn the ignition key to “Start.” When
the engine starts, let go of the key. Thl
idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in “Start” for
longer than 15 seconds at a time will
cause your battery to be drained
much sooner. And the excessive heat
can damage your starter motor.

Don’t drive in “2” (Second Gear) for
more than
5 miles (8 km), or at
speeds over
55 mph (88 km/h), or
you can damage your transmission.
Use or “D” as much as possible.
Don’t shift into
“2” unless you are
going slower than
65 mph (1 05
km/h), or you can damage your
engine.
0 1 (First Gear)
This position gives you even more power
(but lower fuel economy) than
“2.” You
can use it on very steep hills, or in deep
snow or mud. If the selector lever is put
ir
“1,” the transmission won’t shift into first
gear until the vehicle is going slowly
enough.
NOTICE:
If your rear wheels can’t rotate, don’t
try to drive. This might happen if you
were stuck in very deep sand or mud
or were up against a solid object. You
could damage your transmission.
Also, if you stop when going uphill,
don’t hold your vehicle there with
only the accelerator pedal. This
could overheat and damage the
transmission. Use your brakes or
shift into
“P” (Park) to hold your
vehicle in position on a hill.
Maximum engine speed is limited to
protect driveline components from
improper operation.

the
clutch pedal and the brake pedal, and
shift to “Neutral.”
Neutral - Use this position when
you start or idle your engine.
R (Reverse) - To back up, press
down the clutch pedal, and shift into
“R.” If the shift lever has a ring on it,
you have to lift the ring before you
can shift into
“R” (Reverse). If you
don’t have the ring, just apply
pressure to get the lever past
“5” and
“6” into “R” (Reverse). Let up on the
clutch pedal slowly while pressing the
accelerator pedal.
Shift Speeds (MANUAL TRANSMISSION)
This chart shows when to shift to the next higher gear for best fuel economy.

[f your speed drops below 20 mph
(30 kmh), or if the engine is not running
smoothly, you should downshift to the
next lower gear.
You may have to
downshift two or more gears to keep the
zngine running smoothly or for good
performance.
I NOTICE:
When you are shifting gears, don’t
move the gear shift lever around
needlessly. This can damage parts of
the transmission and may require
costly repair. Just shift directly into the next appropriate gear.

Downloaded from www.Manualslib.com manuals search engine One to Four Light
(MANUAL TRANSMISSION)
When this light comes on, you can only
shift from “1” to
“4” instead of “1” to
“2.” This helps you get the best possible
fuel economy.
This light will come on when:
The engine coolant temperature is
higher than 170°F (77”C),
You are going 15- 19 mph (24-29
kmh), and
You are at 21% throttle or less.
When this light is on, the shift lever will
only let you shift from “1” to
“4.” After
you are in “4,” you can press the clutch
again and shift into another gear. Use the following shift speeds
when the “ONE
TO FOUR’ light is on:
1st to 4th..
....... 15 mph (24 km/h)
4th to 5th ........ 25 mph (40 kmh)
5th to 6th ........ 40 mph (64 km/h)
Each time you come to a stop, your
vehicle’s Engine Control Module (ECM)
determines when to activate
the
One-to-Four upshift system.
Use
“2” only when you accelerate very
quickly from a stop. You can then follow
the full gear shift pattern.
Downshifting
(MANUAL TRANSMISSION)
When you downshift, don’t skip more
than one gear. For example, you can shift
from
“6” to “5” or from “6” to “4.” But
don’t shift from
“6” to “3.”
Be careful not to drive faster than the
speeds shown for each gear:
1st
.............. 40 mph (64 kmh)
2nd
............. 60 mph (97 kmh)
3rd
............ 80 mph (1 29 kmh)
4th ........... 105 mph (169 kmh)
I NOTICE:
If you skip more than one gear when
you downshift, or if you race the
engine when you downshift, you can
damage the clutch or transmission.
~~
The six-speed transmission has springs
that center the shift lever near
“3” and
“4.” These springs help you know which
gear you are in when you are shifting. Be
careful
when shifting from “1” to “2” or
downshifting from “6” to
“5.” The spring;
will try to pull the gear shift lever toward
“3” and “4.” Make sure you move the
lever into
“2” or “5.” If you let the lever
move
in the direction of the pulling, you
may end up shifting from
“1” to “4” or
from
“6” to “3.”

pedal.
I- W
To Resume a Set Speed
Suppose you set your Cruise Control at a
desired speed and then you apply the
brake or clutch pedal. This, of course,
shuts
off the Cruise Control. But you
don’t need to reset
it. Once you’re going
about
25 mph (40 km/h) or more, you ca~
move the Cruise Control switch to
“WA” (Resume/Accelerate) for about ha1
a second.
You’ll go right back up to your chosen
speed and stay there.
To Increase Speed While Using Cruise
Control
There are two ways to go to a higher
speed. Here’s the first:
1. Use the accelerator pedal to get to the
higher speed.
2. Push the button at the end of the lever,
then release the button and the
accelerator pedal. You’ll
now cruise at
the higher speed.
Here’s the second way to go to a higher
speed:
1. Move the Cruise switch to WA.”
Hold it there until you get up to the
speed you want, and then release the
switch.
To increase your speed in very small
amounts, move the switch to
“WA”
for less than half a second and then
release it. Each time you do this, your
vehicle will go about one mph
(1.6 km/h) faster.
To Reduce Speed While Using Cruise
Control
There are two ways to reduce your speed
while using cruise control:
1.
2.
Push in the 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,
push the button for less than half a
second. Each time you do this, you’ll
go one 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 will slow down to the
Cruise Control speed you set earlier.
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 may have to step on
the accelerator pedal to maintain your
speed. 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 don’t use Cruise
Control on steep hills.

:o Get Out of Cruise Control
’here are several ways to turn off the
bise Control:
. Step lightly on the brake pedal or push
the clutch pedal, if you have a manual
transmission;
OR
!. Move the Cruise switch to “OFF.”
ro Erase Speed Memory
Nhen you turn off the Cruise Control or
he ignition, your Cruise Control set speed
nemory is erased.
Operation of Lights
4lthough your vehicle’s lighting system
:headlights, parking lights, fog lamps,
sidemarker lights and taillights) meets all
applicable federal lighting requirements,
2ertain states and provinces may apply
their own lighting regulations that may
require special attention before you
operate these lights.
For example, some jurisdictions may
require that you operate your fog lamps
only when your lower beam headlights
are also on, or that headlights be turned
on whenever you must use your
windshield wipers. In addition, most
jurisdictions prohibit driving solely with
parking lights, especially at dawn or dusk.
It is recommended that you check with
your own state or provincial highway
authority for applicable lighting
regulations.

3. Install the filler plug. Be sure the plug
is fully seated.
Hydraulic Clutch
The clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder
reservoir is filled with hydraulic clutch
fluid.
It isn’t a good idea to “top
off’ your
clutch fluid. Adding fluid won’t correct a
leak.
A fluid loss in this system could indicate
a problem. Have the system inspected and
repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to
determine how often you should check
the fluid level in your clutch master
cylinder reservoir and for the proper fluid. See
“Owner Checks and Services’’ and
“Recommended Fluids and Lubricants”
in the Index.
How to Check and Add Fluid
The clutch master cylinder is under the
Engine Control Module
(ECM) in the left
rear area of the engine compartment.
To check the fluid, look at the area
between the
ECM and the battery.
To add fluid, remove the ECM unit.
