Your vehicle may be equipped with the Passlock
theft-deterrent system.
To find out if your vehicle has
Passlock, turn the ignition key to RUN position.
If the
THEFT SYSTEM light comes on, then your vehicle is
equipped with Passlock. Passlock
is a passive
theft-deterrent system. The system is armed once the
key is removed from the ignition. Passlock enables fuel
if the ignition lock cylinder is turned with a valid key. If
a correct key is not used, fuel is disabled.
During normal operation, the
THEFT SYSTEM light will
go
off after the engine is started. In the unlikely event that
the engine stalls and the
THEFI’ SYSTEM light flashes,
wait until the light stops flashing before
trying to restart
the engine. Remember to release the key from.the START
position
as soon as the engine starts. If after several tries
the vehicle still does not start, the vehicle may need
service. At
this the, you may also want to check the fuses
(see “Fuses and Circuit Breakers” in the Index).
See your
Chevrolet dealer for service.
If the THEFT SYSTEM light comes on while the engine
is running, a problem has been detected and
the system
may need service. See your Chevrolet dealer for service.
In an emergency, call the Chevrolet Roadside Assistance
Program at 1-800-CHEV USA (1-800-243-8872).
New Vehicle “Break-In”
Your modern Chevrolet doesn’t need an
elaborate “break-in.” But it will perform better
in the long run if you follow these guidelines:
e
e
0
Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (804 h).
Don’t make full-throttle starts.
Avoid making 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.
Don’t tow a trailer during “break-in.” See
“Towing a Trailer’’ in the Index for more
information.

Check your oil level and bring
it to the proper level.
See “Engine Oil” in
the Index.
The oil level monitoring system
only checks the oil
during the brief period between turning the key on and
when the engine starts.
It does not check the oil level
while the engine is running.
Parking
on steep grades may cause the light to come
on even when the oil level is correct. If this happens,
park the vehicle on a level surface and check the oil
level.
If it stays on, or comes on while you are driving, you
may have
a problem with the electrical charging system.
It could indicate that you have a loose generator drive
belt, or another electrical problem. Have
it checked right
away. Driving while this light
is on could drain your
battery.

If Your Vehicle
Is Equipped with OBD I1
(2.3L Code D Engine Only)
Certain vehicles are equipped with a new emission
diagnostic system. You can tell whether your vehicle has
this system by reading your tune-up label located under
the hood. If the label says
“OBD 11” on it. the following
instructions apply.
Your Chevrolet
is equipped with an onboard computer
which monitors operation
of the emission control
system. This system
is called OBD I1 (On-Board
Diagnostics
-- Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
CHECK ENGINE light comes on to
indicate when service is require.d. Malfunctions often
will be indicated by the system before any problem is apparent,
which may prevent more serious damage
tc,
your vehicle. This system is also designed to assist your
service technician
in correctly diagnosing any
malfunction.
The
CHECK ENGINE light should come on, as a check
to show
you it is working, when the ignition is on and
the engine is
not running. This light will also come on
during a malfunction in one of two ways:
Light On Steady: This indicates a system
malfunction has been detected. Drive the vehicle
to
the dealer for service at your first opportunity.
Light Flashing: This indicates a misfire has been
detected which may damage the emission control
system. The damage may be reduced by Iowering the
vehicle speed, reducing the amount
of cargo being
hauled or trailered, avoiding hard acceleration,
or by
avoiding steep uphill grades.
If these actions are
effective,
the light will stop flashing and remain on
steady. Drive the vehicle to a dealer for service. If
the light continues to flash, stop the vehicle. Wait for
a steady light to come on, then drive the vehicle to
a
dealer for service.
