It is important to familiarize yourself with the following terms:Cold tire pressure:
WA R N I N G Never disconnect the battery while the engine is running, or you could damagethe vehicle’s electrical parts. Never short-circuit the battery. This could cause it to overheat and be damaged. Keep sparks, cigarette
s, and flames away
from the battery because the battery couldexplode. Electrolyte (battery acid) is made of corro- sive diluted sulfuric acid. If it spills on nearby parts, it can crack, stain, or dis- color them. And if it gets on your skin orin your eyes, it can cause burns or blind- ness. Please observe the following han- dling instructions:• If electrolyte gets on plastic parts orother nearby parts, wipe it off with a softcloth or chamois soak
ed in a solution of
water and neutral detergent then imme- diately rinse the affected parts withplenty of water.• If electrolyte gets on your hands orclothes, rinse thoroughly with water. If electrolyte gets in
your eyes, flush them
with water immediately and get immedi-ate medical attention.
 Open doors and wind
ows in any closed
space where you may be charging or working with the battery. Always wear protective clothing and gog- gles when working with the battery, or have a skilled automobi
le technician do it.
If you are quick-charging your battery, first disconnect the battery cables. In order to prevent a short-circuit, be sure to disconnect the negative (-) terminal first, and reconnect it last. Battery posts, termin
als and related acces-
sories contain lead
and lead compounds.
Wash hands after handling.NOTE
 Check each battery terminal for corrosion. You can stop more corrosion by washing with a solution of baking soda and water. Grease the posts and cl
amps after cleaning or
tightening them.  Check to see that the battery is securely installed and cannot be
moved. Also check
each terminal for tightness.  If you will not be driv
ing your vehicle for a
long period of time, re
move the battery and
store it in a place where the battery fluid willnot freeze. The batter
y only should be stored
with a full charge.  Before cleaning the ba
ttery, tighten all the
filler port caps to keep
dirt and moisture out.

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 characteristic
s 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 pressure is essential for the safe and satisfactory operation of your vehicle. The wrongtire pressure will cause problems in three major areas:SafetyToo little pressure increases flex- ing in the tire and can cause tirefailure. 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 tiretread. These abnormal wear pat- terns will reduce the tread life, and the tire will have to be replacedsooner.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 pres-sure. Too much pressure gives an uncomfortable and jarring ride. Too little pressure feels as if yourvehicle is slow to respond. Unequal tire pressures can make steering your vehicle uneven andunpredictable.
The tire pressure for your vehicle under normal driving conditions is listed on the placard attached to the driver’s door sill.(Refer to “Tire and loading informa- tion placard” on page 11-3.)
The recommended inflation pres- sures under normal driving condi- tions 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 pres-sures change with outdoor tempera- tures. 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 havingbeen parked for three hours. Cold inflation pres
sure must not go
above the maximum values moldedinto the tire sidewall. After driving several miles, your tire inflation pres- sure may increase 2 to 6 psi (14 to 41kPa) 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 be too low. Check your tires each time you refuel. If one tire looks lower thanthe others, check the pressure for all of them. You should also take the followingsafety precautions:Keep your tires inflated to the rec-ommended pressures. (See the tireand loading information placard attached to the driver’s door sill.)Stay within the recommended load limits.

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 rotation” section on page 9-18.
N00939801240
Tread wear indicators are 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 (1.6 mm).When the bands appear next to one another in two or more places
, replace your tires.
N00939901586
To even out the wear on your tires and make them last
longer, Mitsubi-
shi Motors Corporation recommendsthat you rotate your tires at the mile- age 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 hab- its. Any time you notice unusual wear, rotate your tires as soon as pos-sible. When rotating tires, check for uneven wear, damage, and wheel
Replacing tires and wheels
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 11-5. Only Mitsubishi Motors Genuine wheels should be used. 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.

alignment. Abnormal wear is usually caused by a wrong tire pressure, wheels that are not aligned properly, wheels that are out-of-balance, orsevere braking. Check with an authorized Mitsubishi Motors dealer or a repair facility ofyour 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.Tires that do not have arrows showing rotation direction Front Tires that have arrows

CAUTIONA compact spare tire can beinstalled temporarily in place of a tire that has been removed dur- ing the tire rotation. However, itmust not be included in the regu- lar tire rotation sequence.
CAUTIONIf the tires have arrows (A) indi- cating the correct direction of rotation, swap the front and rear tires on the left-hand side of thevehicle and the front and rear tires on the right-hand side of the vehicle separately. Keepeach tire on its original side of the vehicle. When installing the tires, make sure the arrows pointin the direction in which the wheels will turn when the vehi- cle moves forward. Any tirewhose arrow points in the wrong direction will not perform to its full potential.
