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.
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.
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 engine.
This decal identifies engine displacement and gives
some tune-up specifications.
How to Prepare Your Vehicle for
Inspection/Maintenance (I/M) Testing
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 that
additional mixed city and highway driving is
required to complete the check of the OBD II
system.
