To reduce the possibility of catalytic con- verter damage:  Use UNLEADED GASOLINE ONLY of the type of recommended in “Fuel selec- tion”.  Do not drive with an extremely low fuel level. Running out of gas could damage the catalytic converter.  Do not try to start the engine by pushing or towing the vehicle. If the battery is weak or run down, use jumper cables to properly start the engine.
 Do not idle the engine with any spark plug wires disconnected or removed, such as when performing diagnostic tests.  Do not idle the engine for a long time if it is idling roughly or otherwise obviously malfunctioning.  To prevent the catalytic converter from being damaged from unburned gas, do not race the engine when turning off the igni- tion switch.  Stop driving the vehicle if you think the performance is less than normal, the engine is running oddly or there is any other engine trouble, such as with theignition, etc. If you
are not able to stop
driving immediately, slow down and drive for only a short time. Have an inspectionmade by an authorized Mitsubishi Motors dealer or a repair facility of your choice as soon as possible.  In unusual situations involving major engine problems, a burning odor may indicate severe and abnormal catalyticconverter overheating. If this occurs, stop in a safe place, shut the engine off and let the vehicle cool. Once the engine is cool,immediately take your vehicle to a dealer or a repair facility of your choice for ser- vice.

Use the engine hood release lever (locatedunder the instrument panel near the driver’sdoor) to unlock the engine hood. Pull the lever toward you to release the engine hood latch.
CAUTION Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. If the engine malfunctions or mis- fires, or if your vehicle performance suffers, have it serviced promptly. Running yourvehicle when it is overheated may result in damage to the converter and vehicle.WA R N I N G Do not park or run your vehicle in areas where combustible materials such as dry grass or leaves can come in contact with a hot exhaust, since a fire could occur. Do not put undercoat paint on the cata- lytic converter.

Emission-control system maintenance 9-22 Vehicle care and maintenance

N00940800201
Your vehicle is equipped with an emission- control system that meets all the requirementsof the U.S. Environmental Protection Agency and Environment Canada. The emission-con- trol system is made of:  a positive crankcase ventilation system  an evaporative emission-control system  an exhaust emission-control system
The maintenance services listed in the “WARRANTY AND MAINTENANCE MANUAL” must be performed at the timesor mileages listed to keep the emission-con- trol system working properly. These, and all the other “general” maintenance serviceslisted in this manual, need to be performed to keep your vehicle running properly and reli- ably. You may need more frequent maintenance if you drive your vehicle in harsh conditions such as dusty areas or do a lot of start-and- stop driving. To be sure the emission-control system works properly, have your vehicle inspected and maintained by an authorized Mitsubishi Motors dealer or a repair facility of your
choice following the schedule in the “WAR- RANTY AND MAINTENANCE MAN- UAL”. You should also have an inspection and ser-vice any time you suspect a malfunction.
N00940900215
Spark plugs must fire properly for goodengine performance and emission-control. Do not reuse them by cleaning or regapping. Change them at the mileage listed in the“WARRANTY AND MAINTENANCE MANUAL”.
N00941000037
Check the hose surfaces for any heat and mechanical damage, hard and brittle rubber, cracking, tears, cuts and abrasions. Pay spe- cial attention to the hoses closest to high heatsources such as the exhaust manifold. Check all the hose connections, such as clamps and couplings, to make sure they are secure andthat there are no leaks. If you see any wear or damage, replace the hoses immediately.
N00950100050
Have the valve clearance checked at anauthorized Mitsubishi Motors dealer at the mileage specified in the “WARRANTY ANDMAINTENANCE MANUAL”. If the engine sounds abnormally loud, have adjustments made by an authorizedMitsubishi Motors dealer.
Emission-control system maintenance
NOTE
 To meet government regulations and pro- mote cleaner air, your vehicle is equipped with an onboard diagnostic system (OBD).The engine electronic control module that controls OBD functions stores various data (especially about the exhaust emissions).This data will be erased if the battery cable is disconnected, which could make a rapid diagnosis difficult. Do not disconnect thebattery cable when the engine malfunction indicator (“SERVICE ENGINE SOON” or “Check engine light”) is on.
Spark plugs
NOTE
 Use the spark plugs listed under “Engine specifications” on page 11-5 or plugs that are exactly the same. Other plugs could cause engine damage, performance problems or radio noise.
