“AIR BAG.” The system checks for
electrical malfunctions, and the light tell!
you if there is a problem.
You
will see this light flash for a few
seconds when you turn your ignition to
“Run” or “Start.” Then the light should
2
out, which means the system is ready.
Remember,
if the air bag readiness light
doesn’t come

off.
The system has a feature that makes it
difficult for you to lock your keys in your
vehicle. If you leave your keys in the
ignition and lock the doors,
the system
will unlock the doors as soon as they are

ENTRY” light on the Driver Information
Center should not come on. If the light
does come on for a second or two, then
the PKE system is still on.
You can also check whether the system is
on or
off by closing the door and walking
away with the keys and transmitter.
If the

Transmitter Range
The transmitter range depends on your
vehicle and where you are standing. The
coupe
(A) has an antenna in the driver’s
door and one in the rear area. The
convertible
(B) has one antenna in each
door. The antennas do not require any
maintenance.
Range also depends on how you hold
the transmitter. For best performance,
when you come near your vehicle, hold
the transmitter straight up and down,
so
the keys hang down.
If the range seems to be decreasing,
check the battery
in the transmitter.
Range will decrease if the battery is
low. It will also decrease if more than
one transmitter is in the area. Don’t put
the transmitter in a metal container
because the transmitter won’t work.
Matching Transmitter(s) to Your
Vehicle
Each key chain transmitter is coded to
prevent another transmitter from
unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be
?urchased through your dealer.
Remember to bring any remaining
:ransmitters with you when you go to your dealer. When the dealer matches
the replacement transmitter
to your
vehicle, the remaining transmitters must
also be matched. Once the new
transmitter is coded, the lost transmitter
will not unlock your vehicle.
You can match a transmitter to as many
different vehicles as you own, provided
they are equipped with exactly the same
model -system. (General Motors offers
several different models of these
systems on their vehicles.) Each vehicle
can have only three transmitters
matched to it.
To match transmitters to your
vehicle:
1. Move all transmitters out of range.
2. Turn the ignition on.
3. Push “TRIP ODO’ on the Driver
Information Center twice.
4. Within five seconds press and hold
“FUEL INFO’ until the “PASSIVE
KEYLESS ENTRY” light comes on.
5. Turn the ignition off, but leave the
key in the ignition. The “PASSIVE
KEYLESS ENTRY” light should
begin to flash to show the system is
in programming mode.

I Universal Theft
Deterrent
‘our Corvette has a theft deterrent
larm system. With this system, the
SECURITY” light will flash as you
pen the door (if your ignition is
off).
‘his light reminds you to arm the theft
eterrent system. Here’s how to do it:
. Open the door.
. Lock the door with the power door
lock switch or the Passive Keyless
Entry system. The “SECURITY” lieht
will come on.
. Close all the doors. The “SECURITY’
light should go
off.
... 44
Now, if a door or the hatch is opened
without the key or Passive Keyless Entry
system, the alarm will go
off. Your horn
will sound for three minutes, then it will
go
off to save battery power.
The theft deterrent system won’t
arm if
you lock the doors with a key or manual
door lock, or if you lock the vehicle after
the doors are closed.
If your passenger stays in the vehicle
when you leave with the keys, have the
passenger lock the vehicle after the doors
are closed. This way the alarm won’t
arm,
and your passenger won’t set it off.
Always use your key or the Passive
Keyless Entry system to unlock a door.
Unlocking a door any other way will set
off the alarm.
If you do set off the alarm
accidentally, there are three ways to stop
it:
Unlock any door with your key.
Put the ignition key in the ignition.
Use the Passive Keyless Entry system.
How to Test the Alarm
1. Make sure the rear hatch is latched.
2. Lower a window.
3. Arm the system.
4. Close the doors and wait five seconds.
5. Reach through the open window and
unlock the door from inside. The
alarm should sound.
6. Turn off the alarm.
If the alarm doesn’t go
off, check to see
if the horn works. If not, check the horn
fuse. See “Fuses and Circuit Breakers” in
the Index. If the horn does work, but the
alarm doesn’t go
off, see your dealer.

PASS-Key@
Your vehicle is equipped with the
PASS-Key@ (Personalized Automotive
Security System) theft deterrent system.
PASS-Key@ is a passive theft deterrent
system. This means you don’t have to do
anything different to arm or disarm the
system. It works when you insert or
remove the key from the ignition.
PASS-Key@ uses a resistor pellet in
the ignition key that matches a decoder
in your vehicle. When the PASS-Key@ system
senses that
someone is using the wrong key, it shuts
down the vehicle’s starter and fuel
systems. For about three minutes,
the
starter won’t work and fuel won’t go to
the engine. If someone tries to start your
vehicle again or uses another key during
this time, the shutdown period will start
over again. This discourages someone
from randomly trying different keys with
different resistor pellets in an attempt to
make a match.
The ignition key must be clean and dry
before it’s inserted in
the ignition or the
engine may not start. If the “SECURITY”
light comes on, the key may be dirty or
wet.
If this happens and the starter won’t work,
turn the ignition off. Clean and dry
the
key, wait three minutes and try again. If
the starter still won’t work, wait three
minutes and
try the other ignition key. At
this time, you may also want to check
the
fuses (see “Fuses and Circuit Breakers’’ in
the Index). If the starter won’t work with the
other key, your vehicle needs service.
[f your vehicle does start, the first ignition
key may be faulty. See your Chevrolet
Jealer or a locksmith who can service the
PASS-Key@
However, if you accidentally use a key
that has
a damaged or missing resistor
pellet, you will see no “SECURITY”
light.
You don’t have to wait three
minutes before trying the proper key.
if the resistor pellet is damaged
OF
missing, the starter won’t work. Use the
other ignition key, and see your Chevrolet
dealer or a locksmith who can service the
PASS-Key@ to have a new key made.
If the “SECURITY” light comes on while
driving, have your vehicle serviced as
soon as possible.
If you lose or damage a PASS-Key@
ignition key, see your Chevrolet
dealer or a locksmith who can service
PASS-Key@. In an emergency, call the
Chevrolet Roadside Assistance Program
at
1 -800-CHEV USA (1 -800-243-8872).

Engine Power Switch (ZR-I)
The LT5 engine in your ZR-1 has two sets
of intake runners and fuel injectors. The
primary set can be run alone for normal
engine power, or both sets can be used
for
full engine power.

A green arrow on the instrument panel
will flash in the direction of the
turn or
lane change.
To signal a lane change, just raise or
lower the lever until the green arrow start
to flash. Hold it there until you complete
your lane change. The lever will return b!
itself when you release
it.
As you signal a turn or a lane change, if
the arrows don’t flash but just stay on, a
signal bulb may be burned out and other
drivers won’t see your
turn signal.
If a bulb is burned out, replace it to help
avoid an accident.
If the green arrows
don’t go on at all when you signal a
turn,
check the fuse (see “Fuses” in the Index)
and for burned-out bulbs.
Headlight High/..ow Beam
To change the headlights from low beam
to high or high to low, pull the turn signal
lever all the way toward you. Then
release it. When the high beams are on,
this blue light on the instrument panel

You control the windshield wipers by
turning the band with the wiper symbol
on it.
For a single wiping cycle,
turn the band
to “MIST.” Hold it there until the wipers
start, then let go. The wipers will stop
after one cycle. If you want more cycles,
hold the band on “MIST” longer.
You can set the wiper speed for a long or
short delay between wipes. This can be
very useful in light rain or snow. Turn the
band to choose the delay time. The closer

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your
speed. When you take your foot off the
pedal, your vehicle will slow down to the
Cruise Control speed you set earlier.
Using Cruise Control on Hills
How well your Cruise Control will work
on hills depends upon your speed, load,
and the steepness of the hills. When going
up steep hills, you may have to step on
the accelerator pedal to maintain your
speed. When going downhill, you may
have to brake or shift to a lower gear to
keep your speed down. Of course,
applying the brake takes you out of
Cruise Control. Many drivers find this to
be too much trouble and don’t use Cruise
Control on steep hills.
... 66
:o Get Out of Cruise Control
’here are several ways to turn off the
bise Control:
. Step lightly on the brake pedal or push
the clutch pedal, if you have a manual
transmission;
OR
!. Move the Cruise switch to “OFF.”
ro Erase Speed Memory
Nhen you turn off the Cruise Control or
he ignition, your Cruise Control set speed
nemory is erased.
Operation of Lights
4lthough your vehicle’s lighting system
:headlights, parking lights, fog lamps,
sidemarker lights and taillights) meets all
applicable federal lighting requirements,
2ertain states and provinces may apply
their own lighting regulations that may
require special attention before you
operate these lights.
For example, some jurisdictions may
require that you operate your fog lamps
only when your lower beam headlights
are also on, or that headlights be turned
on whenever you must use your
windshield wipers. In addition, most
jurisdictions prohibit driving solely with
parking lights, especially at dawn or dusk.
It is recommended that you check with
your own state or provincial highway
authority for applicable lighting
regulations.

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.
