Starting and operating/State emission testing (U.S. only) whenever the low fuel warning light illuminates. Engine misfires as a result of an empty tank could cause damage to the engine. State emission testing (U.S. only) WARNING Testing of an All-Wheel Drive model must NEVER be performed on a single two-wheel dynamometer. Attempting to do so will result in uncontrolled vehicle movement and may cause an accident or injuries to persons nearby. CAUTION . At state inspection time, remember to tell your inspection or service station in advance not to place your SUBARU AWD vehicle on a two-wheel dynamometer. Otherwise, serious transmission damage will result. . Resultant vehicle damage due to improper testing is not covered under the SUBARU Limited Warranty and is the responsibility of the state inspection program or its contractors or licensees. California and a number of federal states 7-7 have Inspection/Maintenance programs to inspect your vehicle’s emission control system. If your vehicle does not pass this test, some states may deny renewal of your vehicle’s registration. Your vehicle is equipped with a computer that monitors the performance of the engine’s emission control system. Certified emission inspectors will inspect the On-Board Diagnostic (OBDII) system as part of the state emission inspection process. The OBDII system is designed to detect engine and transmission problems that might cause the vehicle emissions to exceed allowable limits. OBDII inspections apply to all 1996 model year and newer passenger cars and trucks. Over 30 states plus the District of Columbia have implemented emission inspection of the OBDII system. . The inspection of the OBDII system consists of a visual operational check of the “CHECK ENGINE” warning light/malfunction indicator light (MIL) and an examination of the OBDII system with an electronic scan tool. . A vehicle passes the OBDII system inspection if proper operation of the “CHECK ENGINE” warning light is observed, there are no stored diagnostic trouble codes, and the OBDII readiness monitors are all complete. – CONTINUED –
