Treadwear, Traction and Temperature GradesTreadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions 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
government course as a tire graded 100. The relative perfor-
mance of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to
variations in driving habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and
C. Those grades represent the tire’s ability to stop on wet pave-
ment as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature
The temperature grades are A (the highest), B and C, represent-
ing the tire’s resistance to the generation of heat and its ability
to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of performance which
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 test wheel than the
minimum required by law.
Tire inflation pressures
N00939300743
Proper tire inflation pressure is essential for the safe and satis-
factory operation of your vehicle. The wrong tire pressure will
cause problems in three major areas:

Safety
Too little pressure increases flexing in the tire and can
cause tire failure. Too much pressure can cause a tire to
lose its ability to cushion shock. Objects on the road and
potholes could then cause tire damage that may result in
tire failure.

Economy
The wrong tire pressure can cause uneven wear patterns in
the tire tread. These abnormal wear patterns will reduce
the tread life, and the tire will have to be replaced 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 correct tire pressure. Too much
pressure gives an uncomfortable and jarring ride. Too lit-
tle pressure feels as if your vehicle is slow to respond.
Unequal tire pressures can make steering your vehicle
uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the plac-
ard attached to the driver’s door sill.
(Refer to “Tire and loading information placard” on page 9-3.)

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 change severely, because tire pressures change
with outdoor temperatures. The pressures listed are always
“cold inflation pressure”.
Cold inflation pressure is measured after the vehicle has been
parked for at least three hours 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 sidewall. 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 pressure
will be too low.
Check your tires each time you refuel. If one tire looks lower
than the others, check the pressure for all of them.
You should also take the following safety precautions:

Keep your tires inflated to the recommended pressures.
(See the tire and loading information placard attached to
the driver’s door sill.)

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 inflating your tires to the correct pressure, check
them for damage and air leaks. Be sure to reinstall the
caps on the valve stems.

Replacing tires and wheels
N00939600283
Tire maintenance
N00939700138
The following maintenance steps are recommended:

Check tire pressures regularly.
Have regular maintenance done on the wheel balance and
front and rear suspension alignment.

Rotate your tires regularly as described in the “Tire rota-
tion” section on page 7-27.
Tread wear indicators
N00939800168
Tread wear indicators are built into the original equipment tires
on your vehicle to help you know when your tires should be
replaced. Many states have laws requiring that you replace
your tires at this point.
These indicators are molded into the bottom of the tread
grooves and will appear when the tire tread is worn down to
1/16 inch (1.6 mm).
CAUTION
!
Avoid using different size tires from the one listed
and the combined use of different types of tires, as
this can affect driving safety.
Refer to “Tires and wheels” on page 9-7.
On all-wheel drive vehicles, always use tires of the
same size, type, and brand that have no wear differ-
ences. Using tires of different size, type, brand or
degree of wear, will increase the differential oil tem-
perature, and result in possible damage to the driv-
ing system. Further, the drivetrain will be subjected
to excessive loading, possibly leading to oil leakage,
component seizure, or other serious problems.
As your vehicle is equipped with a tire pressure
monitoring system, use only Mitsubishi genuine
wheels.
Other wheels do not permit correct installation of
tire inflation pressure sensors and can cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.
See an authorized Mitsubishi Motors dealer when
you replace a tire or wheel.

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
N00939900475
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.

Snow tires
N00940000405
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).
CAUTION
!
A compact spare tire can be fitted 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.
If the tires have arrows (A) indicating the correct
direction of rotation, swap the front and rear tires
on the left-hand side of the vehicle and the front and
rear tires on the right-hand side of the vehicle sepa-
rately. Keep each tire on its original side of the vehi-
cle. When installing the tires, make sure the arrows
point in the direction in which the wheels will turn
when the vehicle moves forward. Any tire whose
arrow points in the wrong direction will not perform
to its full potential.

CAUTION
!
Avoid the combined use of different types of tires.
Using different types of tires can affect vehicle per-
formance and safety.
CAUTION

Other wheels do not permit correct installation of
tire inflation pressure sensors and can thus cause air
leakage and sensor failure, which would not be cov-
ered by your vehicle’s warranty.

7 Wiper blades
N00940700011
Check the wiper blades occasionally. Clean them regularly to
remove deposits of salt and road film. Use a sponge or cloth
and a mild detergent or non-abrasive cleaner to clean the blades
and glass areas.
Replace the blades if they continue to streak or smear.NOTE
Do not run the wipers on dry glass for a long time. This
wears out the rubber and can scratch the glass.During cold weatherIf the blades are frozen to the windshield or rear window, do
not operate the wipers until the ice has melted and the blades
are freed, otherwise the wiper motor may be damaged.
Emission-control system maintenance
N00940800315
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
N00940900127
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 may be 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 9-6 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.Fuel hoses
N00941000011
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Payspecial 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.
Fuel system (tank, pipe line and connection, and
fuel tank filler tube cap)
N00941300131
Check these regularly for damage or leaks in the fuel lines and
connections. Check the fuel tank filler tube cap for damage or
looseness. 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.

The next pages list the maintenance service recommended by
Mitsubishi Motors Corporation. In addition to the general
maintenance that needs to be performed at the times listed,
there are other parts which do not usually need regular mainte-
nance.
But, if any of these parts stops working properly, your vehicle
performance could suffer. Have these items checked if you
notice a problem with them.
See your authorized Mitsubishi Motors dealer for assistance, if
you have any questions.Disc brake pads
N00941600020
Good brakes are essential to safe driving. Check the brake pads
for wear. For good braking performance, replace the brake pads
with the same type pads as the originals.Brake hoses
N00941700089
Brake hoses and tubing should be checked for:

Severe surface cracking, scuffing or worn spots. If the
fabric casing of the hose is showing through any cracks or
worn spots in the rubber hose cover, the hose should be
replaced. The brakes can fail if the hose wears through.

Improper installation may cause twisting, or wheel, tire or
chassis interference.
