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 Canada, vehicle
owners may be liable if their emission control device
is removed or prevented from working.
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.
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, surged, stalls or backfires.
Information about your vehicle's emission 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.
Readiness for inspection/maintenance 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.
The driving modes required to reach the ready
condition consist of a minimum of 30 minutes of city
and highway driving as described below:
²At least twenty minutes driving in stop and go,
city type traffic with at least four idle periods.
