Driving through Deep Standing Water
NOTICE:
If you drive too quickly through deep
puddles or standing water, water can
come in through your engine’s air
intake and badly damage your
engine. If you can’t avoid deep
puddles or standing water, drive
through them very slowly.
Rough Idling
If you notice rough idling or surging,
especially after long periods of idling or
during slow city driving, the oxygen
sensors may be clogged. If this happens,
follow these steps to clear the oxygen
sensors:
1. Set the parking brake.
2. Shift an automatic transmission to “P”
(Park) or a manual transmission to
“N’ (Neutral).

Engine Coolant Heater (Engine
Block Heater)
(LTI ENGINE, CANADA)
In very cold weather, 0 “F (- 18 “C) or
colder, the engine coolant heater can help.
You’ll get easier starting and better fuel
economy during engine warm-up.
Usually, the coolant heater should be
plugged in a minimum of four hours prior
to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
3. Plug it into a normal, grounded
1 10-volt outlet.
I NOTICE:
After you’ve used the coolant heater,
be sure to store the cord as it was
before to keep it away from moving
engine parts. If you don’t, it could be
damaged.

Downloaded from www.Manualslib.com manuals search engine How long should you keep the coolant
heater plugged in? The answer depends
on the weather, the kind of
oil you have,
and some other things. Instead of trying
to list everything here, we ask that you
contact your Chevrolet dealer in the area
where you’ll be parking your vehicle. The
dealer can give you the best advice for
that particular area.

Automatic Transmission
There are several different positions for
your shift lever.
P (Park)
This locks your rear wheels. It’s the best
position to use when you start your
engine because your vehicle can’t move
easily. Ensure the shift
lever is fully in
“P”
(Park) range before starting the engine.
Your Corvette has a brake-transmission
shift interlock. You have to fully apply
your regular brakes before you can shift
from “P” (Park) when the ignition key is
in the “Run” position. If you cannot shift
out of
“P” (Park), ease pressure on the
shift lever
- push the shift lever all the

0 Automatic Overdrive
This position is for normal driving. If you
need more power for passing, and you’re:
- Going less than about 35 mph
(56 kmh), push your accelerator
pedal about halfway down.
- Going about 35 mph (56 km/h) or
more, push the accelerator all the way
down.
You’ll shift down to the next gear and
have more power.
D (Third Gear)
This is like 0 , but you never go into
Overdrive.
Here are some times
you might choose
“D’ instead of 0 :
- When driving on hilly, winding roads
- When going down a steep hill
2 (Second Gear)
This position gives you more power but
lower
fuel economy. You can use “2” on
hills. It can help control your speed as
you
go down steep mountain roads, but
then you would also want to use your
brakes
off and on.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
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.

you’ve come to a complete stop and
it’s hard to shift into

and Sixth Gears)
- Shift into “3,”
“4,” “5” and “6” the same way you do
for
“2.” Slowly let up on the clutch
pedal as you press the accelerator
pedal.
To Stop - Let up on the accelerator
pedal and press the brake pedal. Just
before the vehicle stops, press
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.

[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.”

Leaving Your Vehicle with the
Engine Running
(AUTOMATIC TRANSMISSION)
Torque Lock
(AUTOMATIC TRANSMISSION)
If you are parking on a hill and you don’t
shift your transmission into
“P” (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl in
the transmission. You may find it difficult
to pull the shift lever out of
“P’ (Park).
This is called “torque lock.” To prevent torque lock,
set the parking brake and
then shift into
“F’” (Park) properly before
you leave the driver’s seat.
To find out
how, see “Shifting into ‘P’ (Park)” in the
Index.
When you are ready to drive, move the
shift lever out of
“P” (Park) BEFORE
you release the parking brake.
If “torque lock” does occur, you may
need to have another vehicle push yours a
little uphill to take some of the pressure
from the transmission,
so you can pull
the shift lever out of
“P” (Park).
Shifting out of P (Park)
(AUTOMATIC TRANSMISSION)
Your Corvette has a brake-transmission
shift interlock. You have to fully apply
your regular brake before you can shift
from
“P” (Park) when the ignition is in
the “Run” position. See “Automatic
Transmission” in the Index.
If you cannot shift out of “P” (Park),
ease pressure on the shift lever
- push
the shift lever all the way into
“P” (Park)
and release
the shift lever button as you
maintain brake application. Then press
the shift lever button and move the shift
lever into the gear you wish. If you
ever hold the brake pedal down but
still can’t shift out of
“P” (Park), try this:
1. Turn the key to “Off.”
