To replace the oil filter
N00955100013
The oil filter should be replaced at the time or mileage speci-
fied in the “WARRANTY AND MAINTENANCE MAN-
UAL”.
Only use high quality replacement filters on this vehicle. The
manufacturer’s specifications 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 replace-
ment filter.
Follow the installation instructions printed on the filter.
Engine coolant
N00937800438
To check the coolant level 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 tank should 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.

When the bands appear next to one another in two or more
places, replace your tires. NOTE
Tire wear indicators can have different marks and loca-
tions depending on the tire manufacturer.
Tire rotation
N00939900390
To even out the wear on your tires and make them last longer,
Mitsubishi Motors Corporation recommends that you rotate
your tires at the mileage listed in the “WARRANTY AND
MAINTENANCE MANUAL”.
However, the timing for tire rotation may vary according to
your vehicle condition, road surface conditions, and your own
personal driving habits. Any time you notice unusual wear,
rotate your tires as soon as possible.
When rotating tires, check for uneven wear, damage, and wheel
alignment. Abnormal wear is usually caused by a wrong tire
pressure, wheels that are not aligned properly, wheels that are
out-of-balance, or severe braking.
Check with an authorized Mitsubishi Motors dealer or a repair
facility of your choice to find out the reason for uneven tread
wear.
The first tire rotation is the most important one. It will allow all
your tires to wear evenly.
CAUTION
!
A compact spare tire can be installed temporarily in
place of a tire that has been removed during the tire
rotation. However, it must not be included in the
regular tire rotation sequence.

7 Emission-control system maintenance
N00940800201
Your vehicle is equipped with an emission-control system that
meets all the requirements of the U.S. Environmental Protec-
tion Agency and Environment Canada. The emission-control
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 times
or mileages listed to keep the emission-control system working
properly. These, and all the other “general” maintenance ser-
vices listed in this manual, need to be performed to keep your
vehicle running properly and reliably.
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 Mit-
subishi Motors dealer or a repair facility of your choice follow-
ing the schedule in the “WARRANTY AND MAINTENANCE
MANUAL”.
You should also have an inspection and service any time you
suspect a malfunction.
NOTE
To meet government regulations and promote cleaner air,
your vehicle is equipped with an onboard diagnostic sys-
tem (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 the battery
cable when the engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) is on.

Spark plugs
N00940900169
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 MAINTE-
NANCE MANUAL”.
Your vehicle equipped with iridium tipped spark plugs, which
are identified by marks on the ceramic. They do not require
replacement as frequently as the conventional type spare plug
and will last much longer.NOTE
Use the spark plugs listed under “Engine specifications”
on page 9-7 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.
Fuel hoses
N00941000037
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Pay
special attention to the hoses closest to high heat sources such
as the exhaust manifold. Check all the hose connections, such
as clamps and couplings, to make sure they are secure and that
there are no leaks. If you see any wear or damage, replace the
hoses immediately.Ignition cables
N00941100041
The ignition cables should be kept clean, properly connected,
and fully seated. Terminals should be fully seated and the nip-
ple assemblies should not be removed from the coil towers
unless the nipples are damaged or cable testing indicates high
resistance or broken insulation. Cracked or damaged cables
must be replaced.Intake valve clearance
N00950100050
Have the valve clearance checked at an authorized Mitsubishi
Motors dealer at the mileage specified in the “WARRANTY
AND MAINTENANCE MANUAL”.
If the engine sounds abnormally loud, have adjustments made
by an authorized Mitsubishi Motors dealer.Fuel system (tank, pipe line and connection, and
fuel tank filler cap)
N00941300085
Check these regularly for damage or leaks in the fuel lines and
connections. Check the fuel tank filler cap for damage or loose-
ness. Pay special attention to the fuel lines closest to high heat
sources such as the exhaust manifold.

Evaporative emission control system (except
evaporative emission canister)
N00941400116
If the fuel-vapor vent line is clogged or damaged, the fuel-
vapor mixture will escape, polluting the air.
Have the system checked at an authorized Mitsubishi Motors
dealer at the mileage specified in the “WARRANTY AND
MAINTENANCE MANUAL”.
WA R N I N G
!
If you see a fuel leak or if you smell fuel, do not run
the engine. Any spark (including from the ignition),
flame or smoking material could cause an explosion
or fire. Call an authorized Mitsubishi Motors dealer
or a repair facility of your choice for assistance.

How to calculate your gasoline mileage
You can calculate your miles-per-gallon or kilometers-per-litre
by using the following process:
1. Fill your vehicle’s fuel tank and record the odometer mile-
age.
2. Drive your vehicle as you normally do.3. Refill the fuel tank. Record the odometer mileage again,
as well as the gallons/litres of fuel used.
4. Subtract the first mileage number from the second number
to know how many miles/kilometers were driven. Divide
the number of miles/kilometers driven by the number of
gallons/litres of fuel used. This is your approximate miles-
per-gallon or kilometers-per-litre.
