Check Engine Warning Light
*
[LG04550(ALL)05/95]
The Powertrain On-Board Diagnostic II (OBD II)
system consists of the hardware and software
necessary to monitor the operation of the
powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain
control system during normal operation. If an
emission problem is detected, the Check Engine
Warning Light (in the cluster) is turned on.
*
[LG04575(ALL)05/95]
Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
installed. Do not install these devices by tapping
into or running wires close to powertrain control
system wires or components.
[LG04600(ALL)07/95]
The light comes on briefly when you turn the
ignition key to the ON position, but it should
turn off when the engine starts. If the light does
not come on when you turn the ignition to ON
or if it comes on and stays on when you are
driving, have your vehicle serviced as soon as
possible. This indicates a possible problem with
one of the vehicle's emission control systems.
You do not need to have your vehicle towed in.
[LG04650(ALL)08/95]
If the light turns on and off at one (1) second
intervals while you are driving the vehicle, it
means that the engine is misfiring. If this
condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle
serviced at the first opportunity. You do not
need to have your vehicle towed in.
[LG04700(ALL)08/95]
If the light turns on and off on rare occasions
while you are driving, it means that a
malfunction occurred and the condition corrected
itself.

[SV49600(ALL)01/95]
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
*
[SV49700(ALL)01/95]
By law, anyone who manufactures, repairs,
services, sells, leases, trades vehicles, or
supervises a fleet of vehicles is not permitted to
intentionally remove an emission control device
or prevent it from working. In some of the
United States and in Canada, vehicle owners
may be liable if their emission control device is
removed or is prevented from working.
*
[SV49800(ALL)02/92]
Never use a metal exhaust collector when you
service your vehicle. If the metal collector
contacts any of your vehicle's plastic trim or
bumper parts they could melt or deform.
*
[SV49900(ALL)01/95]
Do not drive your vehicle if it does not operate
properly. See your dealer if the engine runs on
for more than five seconds after you shut it off
or if it misfires, surges, stalls, or backfires.

Information about your vehicle's emission
control system is on the Vehicle Emission
Control Information decal located on or near the

Readiness for Inspection/Maintenance
Testing
*
[SV50020(ALL)07/95]
In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. If the
vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to
a not ready for I/M testing condition. To
prepare for I/M testing, the law specifies a
ªneed for additional mixed city and highway
