2 (Second Gear) - Press the clutch
pedal as you
let up on the accelerator
pedal and shift into
“2.” Then, slowly
let up on the clutch pedal as you press
the accelerator pedal.
3,4,5 and 6 (Third, Fourth, Fifth
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.

Malfunction Indicator Lamp (Service Engine Soon Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This light should come on when
the ignition is on,
but the engine is not
running, as a check to show you it is
working. If it does not come on at all,
have it fixed right away. If it stays on, or
it comes on while you are driving, the
computer is indicating that you have a
problem.
You should take your vehicle in
for service soon.
NOTICE:
If you keep driving your vehicle
with this light on, after a while the
emission controls won’t work as
well, your fuel economy won’t be as
good and your engine may not
run as
smoothly. This could lead to costly
repairs not covered by your warranty.

Engine Oil Pressure Gauge
This gauge tells you if there could be a
problem with your engine oil pressure.
The engine oil pressure gauge shows the
engine oil pressure
in psi (pounds per
square inch) or kPa (kilopascals) when
the engine is running. Oil pressure
should be
20 to 80 psi (140 to 550 kPa).
It may
vary with engine speed, outside
temperature and oil viscosity, but readings
above the shaded area show the normal
operating range. Readings in the shaded
area tell you that the engine
is low on oil,
or that you might have some other oil
problem. See “Engine Oil” in the Index.

Low Oil Light
This light should come on while you are
starting your engine. If
the light doesn’t

If the light
comes on while starting your engine and

low. You may need to add oil. See
“Engine Oil” in the Index.

Low Coolant Light
This light comes on when the coolant in
the system is low. You may need to add
coolant. See “Engine Coolant” in the
Index.
NOTICE:
Driving with the “LOW COOLANT”
light on could cause your Corvette to
overheat. See “Engine Overheating”
in the Index. Your Corvette could be
damaged, and it wouldn’t be covered

where you expect to blend with the flow.
Try to merge into the gap
at close to the
prevailing speed. Switch on your turn
signal, check your mirrors and glance
over your shoulder as often as necessary.
Try to blend smoothly with the traffic
flow.
Once you are on the freeway, adjust your
speed to the posted limit or to the
prevailing rate if it’s slower. Stay in the
right lane unless you want to pass.
Before changing lanes, check your
mirrors. Then use your turn signal. Just
before you leave the lane, glance quickly
over your shoulder to make sure there
isn’t another vehicle in your “blind” spot.
Once you are moving on the freeway,
make certain you allow a reasonable
following distance. Expect to move
slightly slower at night.
When you want to leave the freeway,
move to the proper lane well
in advance.
If you miss your exit do not, under any
circumstances, stop and back up. Drive on
to the next exit.
The exit ramp can be curved, sometimes
quite sharply. The exit speed is usually
posted. Reduce your speed according to your speedometer, not
to your sense of
motion. After driving for any distance at
higher speeds, you may tend to think you
are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well
rested. If you must start when you’re not
fresh
- such as after a day’s work -
don’t plan to ,make too many miles that
first part
of the journey. Wear comfortable
clothing and shoes you can easily drive
in.
Is your vehicle ready for a long trip? If
you keep it serviced and maintained, it’s
ready to go. If it needs service, have it
done before starting out. Of course, you’ll
find experienced and able service experts
in Chevrolet dealerships all across North
America. They’ll be ready and willing to
help if you need
it.
Here are some things you can check
before a trip:
Windshield Washer Fluid: Is the
reservoir full? Are all windows clean
inside and outside?
0 Wiper Blades: Are they in good
shape?
0
0
Fuel, Engine Oil, Other Fluids:
Have you checked all levels?
Lights: Are they all working? Are the
lenses clean?
Tires: They are vitally important to a
safe, trouble-free trip.
Is the wead
good enough for long-distance
driving? Are the tires all inflated to
the recommended pressure?
Weather Forecasts: What’s the
weather outlook along your route?
Should you delay your trip
a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”? Or is it jugt plain
falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch
of road with the same scenery, along with
the hum of the tires on the road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you
sleepy. Don’t let it happen to you! If it
does, your vehicle can leave the road in
less than a second, and you could crash
and be injured.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the driver’s door shows the correct
inflation pressures for your tires, when they’re cold. “Cold” means your vehicle has
been sitting for at least three hours or driven no more than a mile.
For competitive driving or high-speed driving (over
150 mph or 240 krn/h), make
sure your tires are inflated to
35 psi (240 kPa). When you end this type of driving,
reduce the “cold” inflation pressures (if necessary) to those listed
on the
Tire-Loading Information label.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is all right. It’s not.
If your tires don’t have enough air (underinflation) you can get:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check: Check your tires
mce
a month or more. Don’t forget
your compact spare tire. It should be at
50 psi (420 Wa).
How to Check: Use a good quality
pocket-type gauge to check tire
pressure. Simply looking at the tires
will not tell you the pressure,
=specially if you have radial tires
-
which may look properly inflated even
if they’re underinflated.
Lf your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Rotation
I’he tires on your Corvette are
lirectional, asymmetrical, and are
different sizes front to rear. Due to this,
your tires should not be rotated. Each
tire and wheel should be used only in
the position it is in.
