Snow tires
N00940000359
In some areas of the country, snow tires are required for winter
driving. If snow tires are required in your area, you must
choose snow tires of the same size and type as the original tires
provided with your vehicle. Snow tires should also be installed
on all four wheels. Otherwise your safety and vehicle handling
can be reduced.
Even where laws may permit it, snow tires should not be oper-
ated at sustained speeds over 75 mph (120 km/h).Tire chains
N00940100015
Clutch pedal free play
(if so equipped)
N00940200045
To check the clutch pedal free play (A), turn off the engine and
press the pedal until you feel resistance.
Clutch pedal free play:
.2 to .5 inch (6 to 13 mm)
CAUTION
!

If flange nuts are used on your vehicle, change to
tapered nuts when using snow tires with steel
wheels.


Only Mitsubishi Motors genuine wheels should be
used, because your vehicle is equipped with a tire
pressure monitoring system.
Use of another type of wheel risks air leaks and sen-
sor damage, as it will not be possible to install the
tire pressure sensor properly.CAUTION
!

Tire chains cannot be used on your vehicle. The
clearance between the chains and the body is not
sufficient to allow proper clearance, and the vehicle
body might be damaged.

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.

Drive belt (for generator, power steering pump,
air conditioning compressor)
N00941900225
Check the tension of the drive belt. Make certain that the indi-
cator (A) is between the specified lines as shown in the illustra-
tion.
Check the drive belt for cuts and cracks, and replace it if it is
damaged. When replacing the belt, make sure that there is no
interference between the belt and other engine components.
After replacing, recheck the tension to make sure the indicator
(A) is between the specified lines.
Exhaust system
N00942200108
The best way to keep carbon monoxide gas from entering
inside your vehicle is to have the engine exhaust system prop-
erly serviced.
Have a competent mechanic inspect the complete exhaust sys-
tem and nearby body areas for broken, damaged, deteriorated,
or mispositioned parts if you notice any of the following:

A change in the sound of the exhaust system


The smell of exhaust fumes inside the vehicle


The underside or rear of the vehicle is damaged
Also check the exhaust system each time the vehicle is raised
for lubrication, oil changes, or required service. Any open
seams or loose connections could let dangerous exhaust fumes
seep into the luggage compartment and passenger compart-
ments.
Check for any of the following conditions:

Check for holes or exhaust gas leaks caused by corrosion
or damage.


Check the joints and connections for looseness or exhaust
gas leaks.


Check the rubber hangers and brackets for damage.
WA R N I N G
!

Do not check or touch the drive belt with the engine
running, or serious injury or death may result.
WA R N I N G
!

Carbon monoxide gas from your vehicle’s exhaust is
poisonous. Breathing these fumes can cause uncon-
sciousness or death.

Hood lock release mechanism and safety catch
N00942500042
The hood lock release mechanism and hood safety catch should
be checked, cleaned, and oiled when needed for easy move-
ment and to stop rust and wear. Use Multipurpose Grease
NLGI Grade 2 sparingly for all sliding parts of the hood latch
and release lever. Work the grease into the hood lock mecha-
nism until all the movable surfaces are covered.
Also, put a light coat of the same grease on the safety catch
wherever moving parts touch.
For cold and snowy weather
N00942600102
Ventilation slotsThe ventilation slots in front of the windshield should be
brushed clear after a heavy snowfall so that the operation of the
heating and ventilation systems will not be impaired.We a t h e r s t r i p p i n gTo prevent freezing of the weatherstripping on the doors,
engine hood, etc., they should be treated with silicone grease.Additional equipment (For regions where snow is
encountered)It is a good idea to carry a shovel or a short-handled spade in
the vehicle during the winter so that you can clear away snow
if you get stranded. A small hand-brush for sweeping snow off
the vehicle and a plastic scraper for the windshield, side and
rear window are also useful.

Polishing
N00946100017
If painted surfaces have been severely damaged and lost their
original luster and color tone, polish the surface lightly with a
fine polishing compound. Avoid limiting your polishing to the
damaged surface only; polish a somewhat wider area, moving
the polishing cloth in one direction. After polishing, flush thecompound from the surface and apply a coat of wax to regain a
beautiful luster.
Damaged paint
N00946200018
Small cracks and scratches in the paint coat should be touched
up as soon as possible with touch-up paint to prevent corrosion.
Check body areas facing the road or the tires carefully for dam-
age to the paint caused by flying stones, etc. The paint code
number for your vehicle can be found on the vehicle informa-
tion code plate in the engine compartment.
CAUTION
!

Waxes containing high abrasive compounds should
not be used. These waxes remove rust and stain
effectively from the paintwork, but are harmful to
the finish on the paint and the plate, because they
also remove clearcoat.
They are also harmful to other glossy surfaces such
as the grille, trim, moldings, etc.


Do not use gasoline, kerosene, benzine or paint thin-
ners to remove road tar or other dirt from the vehi-
cle surface.


Do not put wax on the areas having black matte
coating because it can cause uneven discoloration,
patches, blurs, etc. If these get wax on them, wipe
the wax off right away with a soft cloth and warm
water.


If your vehicle is equipped with a sunroof, be careful
not to apply any wax on the weatherstrip (black
rubber) when waxing the area around the sunroof
opening.
If stained with wax, the weatherstrip cannot main-
tain a weatherproof seal with the sunroof.
