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 “LOCK” position to be safe while you work in the engine com- partment. 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 automotivejack stands. Handling your vehicle’s parts and materi- als in the wrong way can injure you. Ask an authorized Mitsubishi Motors dealer or a repair facility of your choice if youhave 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 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.
N00937501591
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.

Mitsubishi Motors Genuine 0W-20 Synthetic Engine Oil is recommended for optimum fueleconomy and cold weather starting. If Mitsubishi Motors Genuine 0W-20 Syn- thetic Engine Oil is not available, 5W-20grade oils displaying the ILSAC certification can be used. However, Mitsubishi Motors Genuine 0W-20 Synthetic Engine Oil shouldbe used at the next oil change to maintainoptimum fuel economy and cold weather starting.
N00955100042
The oil filter should be replaced at the time ormileage specified in the “WARRANTY AND MAINTENANCE MANUAL”.Only use high quality replacement filters on this vehicle. The manufacturer’s specifica- tions for Genuine Mitsubishi oil filters
require that the filter can withstand a pressure of 256 psi (1.8 MPa). A Genuine Mitsubishi oil filter is the best replacement filter. Follow the installation
instructions printed on
the filter.
N00937801611
The coolant reserve tank (A) lets you quickly see when you need to add coolant. When the engine is cold, the level in the reserve tankshould be between the “FULL” and “LOW” marks. The radiator usually stays full so there is no reason to remove
the radiator 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 blockages in some parts of 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.

Tires
Vehicle care and maintenance 9-17

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlledconditions on a specified government test course. For example, a tire graded 150 would wear one and one- half (1
1/2) times as well on the gov-
ernment course as a tire graded 100. The relative performance of tiresdepends upon the actual conditions of their use, however, and may depart significantly from the norm due tovariations in driving habits, service practices and differences in road characteristics and climate. The traction grades, from highest to lowest, are AA, A, B and C. Thosegrades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on speci- fied government test surfaces of asphalt and concrete. A tire marked C may have poor traction perfor- mance. The temperature grades are A (the highest), B and C, representing the tire’s resistance to the generation ofheat and its ability to dissipate heat when tested under controlled condi- tions on a specified indoor laboratorytest wheel. Sustained high tempera- ture can cause the material of the tire to degenerate and reduce tire life, andexcessive temperature can lead to sudden tire failure. The grade C cor- responds to a level of performancewhich all passenger car tires must meet under the Federal Motor Vehi- cle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory testwheel than the minimum required by law.

Proper tire inflation pressure is essential for the safe and satisfactory operation of yourvehicle. The wrong tire pressure will cause problems in three major areas: Safety Too little pressure increases flexing in thetire and can cause tire failure. Too muchpressure can cause a tire to lose its ability to cushion shock. Objects on the road and potholes could then cause tire damage thatmay result in tire failure. Economy The wrong tire pressure can cause unevenwear patterns in the tire tread. These abnormal wear patterns will reduce the tread life, and the tire will have to bereplaced sooner. Too little pressure also makes it harder for the tire to roll, and this uses up more fuel. Ride comfort and vehicle stability The superior riding experience built into your vehicle partly depends on the correcttire pressure. Too much pressure gives an uncomfortable and jarring ride. Too little pressure feels as if your vehicle is slow torespond. Unequal tire pressures can make steering your vehicle uneven and unpredictable.

The correct tire pressure for your vehicle is listed on the placard attached to the sill of the driver’s door. (Refer to “Tire and loading information plac-ard” on page 11-3.) The recommended inflation pressures should be used for the tires listed below. Tire pressures should be checked, and adjusted if necessary, at least once a month. Pressures should be checked more often whenever weather temperatures changeseverely, because tire pressures change with outdoor temperatures. The pressures listed on the placard are always “cold inflation pres-sure”. Cold inflation pressure
is measured after the
vehicle has been parked for at least threehours or is driven less than 1 mile (1.6 km) after having been parked for three hours.
Cold inflation pressure must not go above the maximum values molded into the tire side- wall. After driving several miles, your tire inflation pressure may increase 14 to 41 KPA,2 to 6 PSI from the cold inflation pressure. Do not let air out of the tires to get back to the specified cold pressure, or your tire pressurewill be too low. Check your tires each time you refuel. If one tire looks lower than the others, check thepressure for all of them.You should also take the following safety pre- cautions: Keep your tires inflated to the recom- mended pressures. (See the tire and load-ing information placard attached to the sill of the driver’s door.) Stay within the recommended load limits. Make sure that the weight of any load in your vehicle is evenly distributed. Drive at safe speeds. After filling your tires to the correct pres- sure, check them for damage and air leaks. Be sure to reinstall the caps on thevalve stems.

Replacing tires and wheels
CAUTION Avoid using different size tires and wheels from the ones listed, and avoid the combined use of different types of tires and wheels. Using different size or type tires and wheelsmay affect driving safety. Refer to “Tires and wheels” on page 11-5. For All-wheel drive vehicles, always use tires of the same size, same type, and same brand, and which have no wear differences.Using tires that differ in size, type, brand or the degree of wear, will increase the differen- tial oil temperature, resulting in possibledamage to the driving system. Further, the drive train will be subjected to excessive loading, possibly leading to oil leakage,component seizure, or other serious prob- lems. Even if a wheel has the same rim size and offset as the specified type of wheel, its shape may prevent it from being fitted cor-rectly. Consult an authorized Mitsubishi Motors dealer or a repair facility of your choice before using wheels that you have. Only Mitsubishi Motors genuine wheels should be used, because your vehicle is equipped with a tire pressure monitoring sys- tem.Use of another type of wheel risks air leaks and sensor damage, as it will not be possible to install the tire pressure sensor properly.

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.
