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

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 insert it all the way into the crankcase. Slowly remove it again.The 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 with
in the “Good” range.
Do not push down strongly on the engine hood. Depending on how strongly or where you push down, you could create a dent in the vehicle body.  For vehicles equipped with the theft-alarm system, if you drive with the engine hood left open, warning display is displayed on theinformation screen in the multi-information display.

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.

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.
N00937901508
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.

The brake fluid and the clutch fluid share thereservoir 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 the engine hood. The brake
system should also be
checked for leaks at the same time.
If the fluid level falls markedly in a short length 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. Use the recommended brake fluid conform- ing to DOT 3 or DOT 4. The reservoir cap must be tightly sealed to keep dirt and water out.
