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
N00939300772
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 9-4.)

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

Tread wear indicators
N00939800054
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).
When the bands appear next to one another in two or more
places, replace your tires. NOTETire 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.

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.NOTEDo 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
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
Mitsubishi Motors dealer or a repair facility of your choice fol-
lowing the schedule in the “WARRANTY AND MAINTE-
NANCE MANUAL”.

Exhaust system
N00942200078
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 cargo area and passenger compartments. 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.

The timing belt should be replaced with a new one at the mile-
age listed in the “WARRANTY AND MAINTENANCE
MANUAL”.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.

5. Use the fuse location diagrams and the matching tables, to
check the fuse that is related to the problem. If the fuse is
not blown, something else must be causing the problem.
Contact an authorized Mitsubishi Motors dealer or a
repair facility of your choice to have the problem checked.6. Insert a new fuse of the same capacity securely into the
appropriate slot. A- Fuse is OK
B- Blown fuse
CAUTION
!Never use a fuse with a capacity greater than the one
listed or any substitute, such as wire, foil etc. This
would cause the circuit wiring to heat up and could
cause a fire. If the replacement fuse blows again after a short
time, have the electrical system checked by an
authorized Mitsubishi Motors dealer or a repair
facility of your choice to find and correct the cause.
