Maintenance and care If you smell exhaust fumes of any kind inside your vehicle, have the dealer inspect and fix your vehicle immediately. Do not drive if you smell exhaust fumes. These fumes are harmful and could kill you. Do not make any unauthorized changes to your vehicle or engine. By law, vehicle owners and anyone who manufactures, repairs, services, 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 "Warranty Guide" 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 "check engine/service engine soon" light is on, reference the applicable light description in the Warning Lights and Chimes section of your owners guide. Your vehicle may not pass the I/M test with the "check engine/service engine soon" light on. 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 test" 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: • First, at least 10 minutes of driving on an expressway or highway. • Next, 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. 159
