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.”

Instrument Cluster
Your instrument cluster and Driver
Information Center are designed to let
you know at a glance how your vehicle is
running. You’ll know how fast you’re
going, about how much fuel you have left
and many other things you’ll need to
know to drive safely and economically. The
center display in
the cluster is
controlled by the Trip Monitor.
Speedometer and Odometer
Your speedometer lets you see your
speed in either miles per hour (mph)
or kilometers per hour (kmh).
Your
odometer shows how far your vehicle has
been driven,
in either miles or kilometers.

Warning Lights, Gauges
and Indicators
This section describes the warning lights
and gauges that may be on your vehicle.
The pictures will help you locate them.
Warning lights and gauges can signal that
something is wrong before it becomes
serious enough to cause an expensive
repair or replacement. Paying attention
to your warning lights and gauges could
also save you or others from injury.
Warning lights go on when there may be
or
is a problem with one of your vehicle’s
functions.
As you will see in the details
on the
next few pages, some warning
lights come on briefly when you turn the
ignition key just to let you know they’re
working. If you are familiar with this
section, you should not be alarmed when
this happens.
Gauges can indicate when there may be
or is a problem with one of your vehicle’s
functions. Often gauges and warning
lights work together to
let you know
when there’s a problem with your vehicle.
... 82
When one of the warning lights comes on
and stays on when you are driving, or
when one of the gauges shows there may
be a problem, check the section that tells
you what to do about
it. Please follow the
manual’s advice. Waiting to
do repairs
can be costly
- and even dangerous. So
please get to know your warning lights
and gauges. They’re a big help.
Your vehicle also has a driver information
center that works along with the warning
lights and gauges. See “Driver Information Center’’
in the Index.
System Problems
If “SYS” flashes on the display near your
fuel gauge, there may be a problem with
your Corvette’s electrical system. If the
“SECURITY” light flashes at the same
time, there is a problem with your theft
deterrent system. Have your vehicle
checked by your dealer
if “SYS’ keeps
appearing.
Gauge Markings
The analog gauges provide a quick visual
reference to the actual measurement of
these gauges. However, you must keep in mind that the gauges aren’t linear. This means that the middle mark is not
a
temperature halfway between the top and
bottom temperatures on the gauge. For
example, the middle mark on the coolant
gauge represents 210°F,
not 180°F as you
might expect.

Downloaded from www.Manualslib.com manuals search engine For your convenience, the following table
gives the reading for each mark.
For numeric gauge measurements, refer to
the digital readings by pressing
“GAUGES” on the Trip Monitor.

Fuel Gauge
Your fuel gauge shows about how much
fuel is in your tank. The bars light up
when the ignition is on or, if the ignition
is
off, when you turn on your parking
lights.
When the display
is down to the last two
bars,
“RESERVE” will appear next to the
gauge.
Here are three concerns some owners
have had about the fuel gauge. All these
situations are normal and do not indicate
that anything is wrong with the fuel
gauge.
At the gas station, the fuel pump shuts
off before the gauge reads
“F.”

It takes more (or less) fuel to fill up
than the gauge reads. For example, the
gauge reads half full, but it took more
(or less) than half of the tank’s
capacity to fill it.
The gauge moves a little when you
turn, stop or speed up.
You can use the Trip Monitor to display
more detailed fuel information. Each time
you press “FUEL INFO,” one

Brake System Warning Light
Your Corvette’s hydraulic brake system
is divided into two parts. If one part isn’t
working, the other part can still work and
stop you. For good braking, though, you
need both parts working well.
This light should come on as you start thc
vehicle. If it doesn’t come on then, have
it fixed
so it will be ready to warn you if
there’s a problem. If this warning light
stays on, there could be
a brake problem.
Have your brake system inspected right
away.
If the light comes on while you are
driving, pull
off the road and stop
carefully. You may notice that the pedal
is harder to push. Or, the pedal may go

T VOLTS I
Voltmeter
You can read the charging system’s rate of
charge on your voltmeter when your
engine is running. When the engine is not
running, the voltmeter shows the voltage
output of yQur battery.
Readings between the shaded areas show
the normal operating range. The reading
will change as the rate of charge changes
(with engine speed, for example), but if
the voltmeter reads
in either shaded area,
and it stays there, you may have a
problem with the charging system. Have
it checked right away. Driving with the
voltmeter reading in a shaded area could
drain your battery. If you must
drive a short distance with the
voltmeter reading
in a shaded area, turn
off all your accessories, including your
comfort controls and audio systems.
For numeric gauge measurements,
press the
“GAUGES’’ button on the
Trip Monitor until “VOLt” appears.
The number that appears next to the fuel

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.
