Engine oil and oil filter 9-6 Vehicle care and maintenance

Mitsubishi Motors recommends using only engine oils with the ILSAC certification sym- bol on the front of the container. If you cannot find oils with the ILSAC certi- fication symbol, use an API classification SNor higher oil with the following label.
This mark appears on th
e top of the oil con-
tainer and tells you two important things about the oil.
N00955001149
Use engine oil with the proper thickness for the outdoor temperatures where you will be driving.
CAUTION Overfilling the crankcase will cause oil aera- tion and loss of oil pressure, which could damage the engine.WA R N I N G Used engine oil is poisonous, and can dam- age your skin. Prolonged and repeated contact may cause serious skin disorders, including dermatitis and cancer. Don’t letused oil touch your skin. Wash thoroughly after working with it. Keep used oil out of the reach of children.NOTE
Engine oil consumption is greatly influenced by payload, engine speed, etc.Vehicles with engine cover

 The engine oil will deteriorate rapidly if the vehicle is subjected to severe conditions (for example, repeated operation on rough roads, in mountainous regions, on roads with many uphill and downhill gradients, or over shortdistances). Consequently, the oil will require earlier replacement in accordance with the schedule in the “WARRANTY AND MAIN-TENANCE MANUAL”.

Air cleaner filter 9-8 Vehicle care and maintenance
9
The radiator cap must be tight sealed to pre- vent losing coolant which may result in engine damage. Only use a Genuine Mitsubi-shi Parts radiator cap, or an approved equiva- lent.
 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 temperature of the engine coolant does not rise after the engine is warmed-up, take your vehicle to an authorized Mitsubishi Motors dealer or a repair facil- ity of your choice to have the thermostatchecked, and replaced if necessary.

The air cleaner filter will get dirty and dustyfrom use and not filter properly. Replace itwith a new filter using the schedule in the “WARRANTY AND MAINTENANCE MANUAL”. 1. Remove the clips (A), then remove the duct (B). 2. While holding down the tab (C), pull out the connector (D).
 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.
Radiator cap
CAUTION
WA R N I N G Wait for the engine to cool down before opening the radiator cap. Otherwise hot steam or boiling coolant could spray up from the radiator and scald you.

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