Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, items, sells,
leases, trades vehicles, or supervises a fleet of vehicles are not permitted
to intentionally remove an emission control device or prevent it from
working. 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.
Please consult your ªWarranty Guideº for complete emission warranty
information.
Readiness for inspection/maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostic (OBD-II) system. If your ªCheck Engine/Service
Engine Soonº light is on, refer to the description in theWarning Lights
and Chimessection of theInstrumentationchapter. Your vehicle may
not pass the I/M test with the ªCheck Engine/Service Engine Soonº light
on.
If the vehicle's powertrain system or its battery has just been serviced,
the OBD-II system is reset to a ªnot ready for I/M testº condition. To
ready the OBD-II system for I/M testing, a minimum of 30 minutes of city
and highway driving is necessary as described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
