The catalytic converter requires you to useunleaded fuel only. Leaded gasoline will destroy the emission-control effectiveness of the converter. Normally, the catalytic converter does not require maintenance. However, it is important to keep the engine properly tuned for the con- verter to continue to work properly.
Service precautions
WA R N I N G When checking or servicing the inside of the engine compartment, be sure theengine is stopped and has had a chance to cool down. If you need to work in the engine compart- ment with the engine running, be espe-cially careful that your clothing, hair, etc. does not get caught in
the fan, drive belts,
or other moving parts.
 After performing the maintenance work, make sure that no tools or cloths are left behind in the engine compartment. If they are left behind, a fire or damage to the vehicle may occur. The fan can turn on automatically even if the engine is not running. Turn the igni-tion switch to the “OFF” position or put the operation mode in OFF to be safe while you work in the engine compart-ment. Do not smoke or allow open flames around fuel or the battery. The fumes are flamma- ble. Be extremely careful when working around the battery. It contains poisonous and corrosive sulfuric acid. Do not get under your vehicle while it is on a jack.Always use properly rated automotive jack stands. Handling your vehicle’s parts and materi- als in the wrong way can injure you. Ask an authorized Mitsubishi Motors dealeror a repair facility of your choice if you have questions.WA R N I N G

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 stopping the engine.  Stop driving the vehicle if you think the performance is noticeably low, or theengine has a malfunction such as with the ignition, etc. If you
are not able to stop
driving immediately, slow down and drivefor only a short time. Have your vehicle checked at an authorized Mitsubishi Motors dealer or a repair facility of yourchoice as soon as possible.  In unusual situations involving major engine problems, a burning odor mayindicate severe and abnormal catalytic converter overheating. If this occurs, stop in a safe place, shut the engine off and letthe vehicle cool. Once the engine is cool, immediately take your vehicle to a dealer or a repair facility of your choice for ser-vice.
N00937501618
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.
Engine hood To open
WA R N I N G Never use the release lever to unlatch the engine hood while the vehicle is in motion. Do not drive your vehicle unless the engine hood is locked.

It is normal for an engi
ne to use oil. You may
need to add oil between the recommended oilchange intervals. Before starting the engine, check the engine oil level. Refill if necessary. To check the oil level, remove the dipstick, wipe it off, and gently reinsert it all the way. Slowly pull the dipstick straight out andcheck the oil level by checking the upper sur- face of the dipstick. Th
e oil level must not go
above the line on the dipstick. If the level does not reach the line which shows the smallest amount of oil required, remove the oil filler cap on the engine valve cover, and fill to within the “Good” range.

The engine coolant reserve tank (A) lets you quickly see when you need to add coolant. When the engine is cold, the level of the cool-ant in the reserve tank should be between the FULL and LOW marks. The radiator usually stays full so there is no reason to remove theradiator cap (B) except when you check the coolant freeze point or replace the antifreeze coolant.
Mitsubishi Motors Genuine Coolant provides excellent protection against corrosion andrust formation on all metals, including alumi- num, and prevents clogs in some parts of the engine.If you need to add co
olant often, or if the
level in the reserve tank does not drop when the engine cools, the cooling system shouldbe pressure-tested for leaks. Take your vehi- cle to an authorized
Mitsubishi Motors dealer
or a repair facility of your choice for testing.
The radiator cap must be tight sealed to pre- vent losing coolant, which may result in engine damage. Only use a GenuineMitsubishi Parts radiator cap, or an approved equivalent.

To add coolant Use “Mitsubishi Motors Genuine Super LongLife Coolant Premium” or equivalent
*.
* : similar high quality ethylene glycol based non-silicate, non-amine, non-nitrate and non-borate coolant with long life hybrid organic acid technologyCAUTION Do not use alcohol or methanol antifreeze or any engine coolants that contain them. Using the wrong antifreeze can corrode aluminum parts.
 The required concentration of anti-freeze dif- fers depending on the expected ambient tem- perature. Above -31 °F (-35 °C) : 50 % concentration of anti-freezeBelow -31 °F (-35 °C) : 60 % concentration of anti-freeze You can check the concentration level with agauge from an automotive supply store, or your authorized Mitsubishi Motors dealer or service station can check it for you. Do not use water to adjust the concentration of coolant. Do not top off the tank with plain water only. Water by itself boils at a lower temperatureand does not stop rust or freezing. If the water freezes, it will damage your cooling system. Do not use tapwater. It can causecorrosion and rust.

 Do not overfill the reserve tank.  Your vehicle uses a special radiator cap that stays sealed and lets the coolant flow from the reserve tank back to the radiatorwhen the engine cools down. If you need to change the cap, use the exact same kind. Check the coolant freeze point in the radi- ator with the proper gauge, and only when it is safe. If you add antifreeze, the con-tents of the reserve tank must be protected against freezing.  Keep the front of the radiator and con- denser clean.  If the engine coolant temperature does not rise after the engine is warmed-up, takeyour vehicle to an authorized Mitsubishi Motors dealer or a repair facility of your choice to have the thermostat checked,and replaced if necessary.

The brake fluid and the clutch fluid share the reservoir tank.
The fluid level must be between the “MAX” and “MIN” marks on the reservoir. The fluid level falls slightly with wear of the brake pads, but this does not indicate any abnormality. The fluid in the master cylinder should be checked when doing other work under theengine hood. The brake system should also be checked for leaks at the same time. If the fluid level falls markedly in a shortlength of time, it indicates leaks from the brake system. If this occurs, have the vehicle checked by anauthorized Mitsubishi Motors dealer or a repair facility of your choice.

Your vehicle is equipped with an emission-control system that meets all the requirements of 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
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 yourchoice. This should be done at the time ormileage specified in the “WARRANTY AND MAINTENANCE MANUAL”. These, and all the other “general” mainte-nance services listed in this manual, need to be performed to keep your vehicle running properly and reliably.You should also have an inspection and ser- vice any time you suspect a malfunction.
N00940900228
Spark plugs must fire properly for good engine performance and emission-control.Do not reuse them by cleaning or regapping. Change them at the mileage listed in the “WARRANTY AND MAINTENANCEMANUAL”.
Wiper blades
NOTE
 Do not run the wipers on dry glass for a long time. This wears out the rubber and can scratch the glass.
During cold weather 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 rapiddiagnosis difficult. Do not disconnect the battery 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 11-4 or plugs that are exactly the same. Other plugs could causeengine damage, performance problems or radio noise.
