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.

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
of the
following will appear next to the fuel
gauge.
INST The fuel economy calculated
for your current driving conditions.
AVERAGE: The fuel economy
calculated for the current tank of fuel,
or since you last reset the display.
RANGE: The distance you can drive
before refueling.
Blank: The fuel gauge is displayed
alone.
You should reset the fuel information
display every time you refuel. Press
“RESET FUEL” on the Trip Monitor. :loser to the floor.
It may
take longer to
stop. If the light is still on, have the
vehicle towed for service. (See “Towing
Your Vehicle” in the Index.)

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

Anti-Lock Brake System Warning
Light
With anti-lock, this light will come on
when you start your engine and may stay
on for about two seconds. That’s normal.
If the light doesn’t come on, have it fixed
so it will be ready to warn you if there is i
problem.
If the light stays on, turn the ignition off.
Or, if the light comes on when you’re
driving, stop as soon as possible and turn
the ignition
off. Then start the engine
again to reset the system. If the light still
stays on, or comes on again while you’re
driving, your Corvette needs service. If
the regular brake system warning light
isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
If the regular
brake system warning light is also on, you
don’t have anti-lock brakes and there’s a
problem with your regular brakes. See
“Brake System Warning Light” earlier in
this part.
