1. If the tire pressure monitoring system warning light illumi
nates, avoid hard
braking, sharp steering maneuvers and high speeds. You should stop and adjust the tires to the proper inflation pressure assoon as possible. Adjust the spare tire at the same time. Refer to “Tires” on page 9-12.
2. If the tire pressure monitoring system warning light remains illuminated afteryou have been driving for approximately 20 minutes after you adjust the tire infla- tion pressure, one or more of the tires mayhave a puncture. Inspect the tire and if it has a puncture, have it repaired by an authorized Mitsubishi Motors dealer assoon as possible.
The tire pressure monitoring system may not work normally in the following circum- stances:  A wireless facility or device using the same frequency is near the vehicle.  Snow or ice is stuck inside the fenders and/or on the wheels. The tire inflation pres
sure sensor’s battery
is dead.  Wheels other than Mitsubishi Motors Genuine wheels are being used.  Wheels that are not fitted with tire infla- tion pressure sensors are being used. Wheels whose ID codes are not memo- rized by the vehicle are used.  Compact spare tire is fitted on a road wheel.  A window tint that affects the radio wave signals is installed.
If the warning light illuminates while driving

NOTE
 When inspecting or adjusting the tire pres- sure, do not apply excessive force to the valve stem to avoid breakage.  After inspecting or adju
sting the tire pres-
sure, always reinstall the valve cap on thevalve stem. Without the valve cap, dirt or moisture could get into the valve, resulting in damage to thetire inflation pressure sensor.  Do not use metal valve caps, which may cause a metal reaction, resulting in corrosion and damage of the tire inflation pressure sen- sors.  Once adjustments have
been made, the warn-
ing light will go off after a few minutes ofdriving.
WA R N I N G If the warning light illuminates while you are driving, avoid ha
rd braking, sharp
steering maneuvers and high speeds. Driving with an under-inflated tire adversely affects vehicle performance andcan result in an accident.CAUTION The warning light may
not illuminate imme-
diately in the event of
a tire blowout or rapid
leak.NOTE
 To avoid the risk of damage to the tire infla- tion pressure sensors, have any puncturedtire repaired by an authorized Mitsubishi Motors dealer. If the tire repair is not done by an authorized Mitsubishi Motors dealer,damage to the tire infl
ation pressure sensor is
not covered by your warranty.
 Do not use an aerosol puncture-repair spray on any tire.Such a spray could damage the tire inflationpressure sensors. Have any puncture repaired by an authorized Mitsubishi Motors dealer.NOTE

The recommended inflation pressures under normal driving conditions should be used forthe 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 (14 to 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 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 pre- cautions:  Keep your tires inflated to the recom- mended pressures. (See the tire and load-ing 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 pres- sure, check them for damage and airleaks. 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” section on page 9-17.

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.
 If your vehicle is equippe
d with a tire pres-
sure monitoring system, only MitsubishiMotors 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.

Emission-control system maintenance 9-20 Vehicle care and maintenance

N00940800328
Your vehicle is equi
pped with an emission-
control system that me
ets all the requirements
of the U.S. Environmental Protection Agencyand Environment Cana
da. The emission-con-
trol system is made of:  a positive crankcase ventilation system  an evaporative emission-control system  an exhaust emission-control system
To be sure the emission-control system works properly, have your vehicle inspected andmaintained 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.
N00940900228
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 MAINTENANCE MANUAL”.
N00941000040
Check the hose surfaces for any heat and mechanical damage, ha
rd and brittle rubber,
cracking, tears, cuts and abrasions. Pay spe-cial attention to the hos
es closest to high heat
sources such as the exhaust manifold. Check all the hose connections, such as clamps andcouplings, to make sure they are secure and that there are no leaks. If you see any wear or damage, replace the hoses immediately.
N00950100050
Have the valve clea
rance checked at an
authorized Mitsubishi Motors dealer at the mileage specified in
the “WARRANTY AND
MAINTENANCE MANUAL”.If the engine sounds ab
normally loud, have
adjustments made by an authorized Mitsubishi Motors dealer.

Check these regularly for damage or leaks in the fuel lines and conne
ctions. Check the fuel
tank filler cap for dama
ge or looseness. Pay

Emission-control system maintenance
NOTE
 To meet government
regulations and pro-
mote cleaner air, your
vehicle is equipped
with an onboard diagnostic system (OBD).The engine electroni
c control module that
controls OBD functions
stores various data
(especially about th
e exhaust emissions).
This data will be erased if the battery cable is disconnected, which c
ould make a rapid
diagnosis difficult.
Do not disconnect the
battery cable when the engine malfunction indicator (“SERVIC
E ENGINE SOON” or
“Check engine light”) is ON.
Spark plugs
NOTE
 Use the spark plugs listed under “Engine specifications” on page
11-5 or plugs that are
exactly the same. Othe
r plugs could cause
engine damage, perf
ormance problems or
radio noise.
