[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.
*
[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.

Readiness for Inspection/Maintenance
Testing
*
[SV51457( ALL)05/95]
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
driving to complete the checkº of the OBD II
system. As soon as all of the OBD II system
checks are successfully completed, the OBD II
system is set to the ready condition. The amount

varies with individual driving patterns. To
complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle
defined below. If the vehicle owner cannot or
does not want to do the additional driving
required by law, a service center can perform
this drive cycle as it would any other type of
repair work.
