NOTICE:
Your modern Corvette doesn’t need
an elaborate “break-in.” But it will
perform better in the long run if you
follow these guidelines:
0 Keep your speed at 55 mph
(88 km/h) or less for the first
500 miles (804 km).
Don’t drive at any one speed
- fast or slow - for the
fist
500 miles (804 km).
Don’t make full-throttle
starts.
Avoid malung hard stops for
the first
200 miles (322 km)
or so. During this time your
new brake linings
aren’t yet
broken in.
Hard stops with
new linings can mean
premature wear and earlier
replacement. Follow this
“breaking-in” guideline
every time you get new
brake linings.

Ignition Switch
With the ignition key in the ignition
switch, you can turn the switch to five
positions:
Acc (A): Position in which you can
operate your electrical power accessories.
Press in the ignition switch as you turn
the top of it toward you.
Lock (B): The only position in which
you can remove the key. This locks your
steering wheel, ignition and automatic
transmission.
If you have an automatic transmission, tht
ignition switch can’t be turned to “Lock”
unless the shift lever
is in the “P” (Park)
position.
... 46
Off (C): Unlocks the steering wheel,
ignition and automatic transmission, but
does not send electrical power to any
accessories. Use
this position if your
vehicle must be pushed
or towed.
Run (D): Position to which the switch
returns after you start your engine and
release the switch. The switch stays in
the “Run” position when the engine is
running. But even when the engine is not
running, you can use “Run” to operate
your electrical power accessories and to
display some instrument panel warning
and indicator lights.
Start (E): Starts the engine. When the
engine
starts, release the key. The ignition
switch will return to “Run” for normal
driving.
When the engine is not running, “Acc”
and “Run” allow you to operate your
slectrical accessories, such as the radio.
A warning tone will sound if you open
the driver’s door when the ignition is in
“Off,’’ “Lock” or “Acc” and the key is in
the ignition.

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 While driving on a surface with reduced
traction, try your best to avoid sudden steering, acceleration, or braking
(including engine braking by shifting to
a lower gear). Any sudden changes could
cause the tires to slide.
You may not
realize the surface is slippery until your vehicle is skidding. Learn to recognize
warning clues
- such as enough water,
ice or packed snow on the road to make a
“mirrored surface”
- and slow down
when you have any doubt.
Remember: Any anti-lock braking system (ABS) helps avoid only the braking skid.

1 Driving at Night
Night driving is more dangerous than day
driving. One reason is that some drivers
are likely to be impaired
- by alcohol or
drugs, with night vision problems, or by
fatigue.
Here are some tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.
0 Adjust your inside rearview mirror to
reduce the glare from headlights
behind you.
Since you can’t see as well, you may
need to slow down and keep more
space between you and other vehicles.
Slow down, especially on higher
speed roads. Your headlights can light
up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull off the road in a
safe place and rest.
Night Vision
No one can see as well at night as in
the daytime. But as we get older these
differences increase.
A 50-year-old
driver may require at least twice as much
light to see the same thing at night as a
20-year-old.
What you do in the daytime can also
affect your night vision. For example, if
you spend the day in bright sunshine you
are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night.
But if you’re driving, don’t wear
sunglasses at night. They may cut down
on glare from headlights, but they also
make a lot of things invisible.
You can be temporarily blinded by
approaching lights. It can take
a second
or two, or even several seconds, for your
eyes to readjust to the dark. When you are
faced with severe glare (as from a driver
who doesn’t lower the high beams, or a

Remove the nut on the outboard side
of the unit. Then loosen the front and
inboard nuts. For the LT5 engine, loosen
the two inboard nuts. Move the ECM unit
to either side.
Fluid should be added if the fluid level
is at or below the “ADD” mark on the
reservoir. There are additional instructions
on the reservoir cap.
When returning the ECM to its proper
position, make sure the bolts are aligned
with the slots in the bracket. Then gently
push down on the unit. When replacing
the unit, be careful not to over-tighten the
nuts -just tighten them until they are
snug.

When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant. See “Periodic Maintenance
Inspections” in the Index.
How to Check Lubricant
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant. Add enough lubricant to raise
the level to the bottom of the filler plug
hole.
What to Use:
To add lubricant when the level is low, use
Axle Lubricant (GM Part
No. 12345977)
or
SAE 8OW-90 GL-5 gear lubricant.
To completely refill after draining,
add 4 ounces (1 18 ml) of Limited-Slip
Differential Lubricant Additive (GM Part
No. 1052358). Then fill to the bottom of
the filler plug hole with Axle Lubricant
(GM Part
No. 12345977) or SAE 8OW-90
GL-5 gear lubricant.
Engine Coolant
The following explains your cooling
system and how to add coolant when
it
is low. If you have a problem with
engine overheating or
if you need to add
coolant to your high fill reservoir, see
“Engine Overheating” in the Index.
The proper coolant for your Corvette will:
0
0
0
0
0
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F
(128°C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.
