Maximum load indicates the maxi- mum load this tire is designed to carry.
Maximum Pressure indicates the maximum permissible cold tire infla- tion pressure for this tire. The TIN may be found on one or both sides of the tire but the datecode may only be on one side. Look for the TIN on the outboard side of tires as mounted on the vehicle. If theTIN is not found on the outboard side then you will find it on the inboard side of the tire.
Temporary spare tires are highpressure compact spares designed for temporary emer- gency use only. Tires designedto this standard have the letter “T” molded into the sidewall preceding the size designation.Example: T145/80D18 103M.

The treadwear grade is a comparative rating based on the wear rate of thetire when tested under controlled conditions on a specified government test course. For example, a tiregraded 150 would wear one and one- half (1
1/2) times as well on the gov-
ernment course as a tire graded 100. The relative performance of tires depends upon the actual conditionsof their use, however, and may depart significantly from the norm due to variations in driving habits, servicepractices and differences in road characteristics and climate. The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on speci- fied government test surfaces of asphalt and concrete. A tire marked C may have poor traction perfor-mance. The temperature grades are A (the highest), B and C, representing thetire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled condi-tions on a specified indoor laboratory test wheel. Sustained high tempera- ture can cause the material of the tireto degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C cor-responds to a level of performance which all passenger car tires must meet under the Federal Motor Vehi-cle Safety Standard No. 109. GradesB and A represent higher levels of performance on the laboratory test wheel than the minimum required bylaw.

Proper tire inflation pres
sure is essential for
the safe and satisfactory 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 andpotholes 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 thetread life, and the tire will have to be replaced sooner. Too little pressure also makes it harder forthe 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 mu
ch pressure gives an
uncomfortable and ja
rring ride. Too little
pressure feels as if your vehicle is slow to respond. Unequal tire pressures can make steeringyour vehicle uneven and unpredictable.
The tire pressure for your vehicle under nor- mal driving conditions is listed on the placardattached to the driver’s door sill. (Refer to “Tire and loading information plac- ard” on page 11-3.)The recommended infl
ation pressures under
normal driving conditions 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 changeseverely, becaus
e 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 side-
wall. After driving seve
ral miles, your tire
inflation pressure may increase 2 to 6 psi (14to 41 kPa) from the cold inflation pressure. Do not let air out of the tires to get back to the specified cold pressure, or your tires will betoo low. Check your tires each time you refuel. If one tire looks lower than the others, check thepressure for all of them. You should also take the following safety pre- cautions: Keep your tires inflated to the recom- mended pressures. (See the tire and load- ing information placard attached to thedriver’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 pres- sure, check them for damage and air leaks. Be sure to reinstall the caps on the valve stems.

The following maintenance steps are recom- mended: Check tire pressures regularly. Have regular maintenance done on the wheel balance and front
and rear suspen-
sion alignment. Rotate your tires regularly as described in the “Tire rotation” se
ction on page 9-22.

Tread wear indicators ar
e built into the origi-
nal equipment tires on
your vehicle to help
you know when your tires should be replaced. Many states have la
ws 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 (1.6mm). When the bands appear next to one another in two or more places
, replace your tires.
Replacing tires and wheels
CAUTIONAvoid using different size tires from the one listed and the combined use of differenttypes of tires, as this can affect driving safety. Refer to “Tires and wheels” on page 11-7. On all-wheel drive vehi
cles, always use tires
of the same size, same
type, and same brand,
and which have no wear differences. Using tires that differ in si
ze, type, brand or the
degree of wear, will increase the differentialoil temperature, resulting in possible damage to the driving system. Further, the drive train will be subjected to ex
cessive loading, possi-
bly leading to oil leakage, component sei- zure, or other serious problems. Only Mitsubishi Motors Authorized wheels should be used, beca
use your vehicle is
equipped with a tire pr
essure monitoring sys-
tem. Use of another type of wheel risks air leaks and sensor damage, as it
will not be possible
to install the tire pressure sensor properly.
NOTE
On vehicles with Elec
tric parking brake, 16
inches steel wheel cannot be used on yourvehicle because it interfe
res with brake parts.
Additionally, 16 inches aluminum wheel may not be used on
your vehicle depending
on its type, even if a Mitsubishi Motors Gen-uine wheels. Consult an authorized Mitsubishi Motors dealer before using
wheels that you have.

To even out the wear on your tires and make them last longer, Mitsubishi Motors Corpora- tion recommends that y
ou rotate your tires at
the mileage listed in the “WARRANTY AND MAINTENANCE MANUAL”. However, the timing for tire rotation mayvary according to your vehicle condition, road surface conditions, and your own per- sonal driving habits. Any time you notice unusual wear, rotate your tires as soon as pos- sible. When rotating tires, check for uneven wear, damage, and wheel alignment. Abnormal wear is usually caused by a wrong tire pres- sure, wheels that ar
e not aligned properly,
wheels that are out-of-balance, or severe braking. Check with an author
ized 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.

In some areas of the country, snow tires are required for winter driving. If snow tires are required in your area, you must choose snowtires of the same size
and type as the original
tires provided with your vehicle. Snow tires should also be installe
d on all four wheels.
Otherwise your safety and vehicle handling can be reduced. Even where laws may permit it, snow tiresshould not be operated
at sustained speeds
over 75 mph (120 km/h).
Tire rotation
CAUTION A compact spare tire (i
f so equipped) can be
installed temporarily in
place of a tire that
has been removed duri
ng the tire rotation.
However, it must not
be included in the regu-
lar tire rotation sequence. If the tires have arrows (A) indicating the correct direction of ro
tation, swap the front
and rear tires on the le
ft-hand side of the
vehicle and the front
and rear tires on the
right-hand side of th
e vehicle separately.
Keep each tire on its original side of the vehicle. When installing the tires, make surethe arrows point in the
direction in which the
wheels will turn when the vehicle moves for- ward. Any tire whose arrow points in thewrong direction will not
perform to its full
potential.

Check the wiper blades occasionally. Clean them regularly to remove
deposits of salt and
road film. Use a sponge or cloth and a milddetergent or non-abrasive
cleaner to clean the
blades and glass areas. Replace the blades if th
ey continue to streak
or smear. If 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 mo
tor may be damaged.

Your vehicle is equi
pped with an emission-
control system that me
ets all the requirements
of the U.S. Environmental Protection Agency
and Environment Cana
da. The emission-con-
trol system is made of: a positive crankcase
ventilation system
an evaporative emis
sion-control system
an exhaust emission-control system
To be sure the emissi
on-control system works
properly, have your ve
hicle inspected and
maintained by an authorized Mitsubishi Motors dealer or a repair facility of your choice. This should be done at the time or mileage specified in the “WARRANTY AND MAINTENANCE MANUAL”.These, and all the other “general” mainte- nance services listed in this manual, need to be performed to keep
your vehicle running
properly and reliably. You should also have
an inspection and ser-
vice any time you suspect a malfunction.

Spark plugs must fire properly to ensure proper engine perfo
rmance and emission-
control.Do not reuse spark plugs by cleaning or regapping. Spark plugs sh
ould be replaced at
the mileage specified in the “WARRANTYAND MAINTENANCE MANUAL”.
Wiper blades
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 weather Emission-control system maintenance
NOTE
To meet government regulations and pro- mote cleaner air, your
vehicle is equipped
with an onboard dia
gnostic system (OBD).
The engine electronic control module that controls OBD functions stores various data (especially a
bout 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
NOTE
Use the recommended or
equivalent spark
plugs listed under “Engine specifications” onpage 11-6. Use of other plugs could cause engine damage, loss of
performance or radio
noise.
