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.
Replacing tires and wheels
N00939600241
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 9-10.On all-wheel drive vehicles, always use tires of the
same size, same type, and same brand, and which
have no wear differences. Using tires that differ in
size, type, brand or the degree of wear, will increase
the differential oil temperature, resulting in possible
damage to the driving system. Further, the drive
train will be subjected to excessive loading, possibly
leading to oil leakage, component seizure, or other
serious problems.Only Mitsubishi Motors Authorized wheels should
be used, because your vehicle is equipped with a tire
pressure monitoring system.
Use of another type of wheel risks air leaks and sen-
sor damage, as it will not be possible to install the
tire pressure sensor properly.

Spark plugs
N00940900231
Spark plugs must fire properly to ensure proper engine perfor-
mance and emission-control.
Do not reuse spark plugs by cleaning or regapping. Spark plugs
should be replaced at the mileage specified in the “WAR-
RANTY AND MAINTENANCE MANUAL”.NOTEUse the recommended or equivalent spark plugs listed
under “Engine specifications” on page 9-9. Use of other
plugs could cause engine damage, loss of performance or
radio noise.Fuel hoses
N00941000040
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Pay
special 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.Intake valve clearance
N00950100050
Have the valve clearance checked at an authorized Mitsubishi
Motors dealer at the mileage specified in the “WARRANTY
AND MAINTENANCE MANUAL”.
If the engine sounds abnormally loud, have adjustments made
by an authorized Mitsubishi Motors dealer.
Fuel system (tank, pipe line and connection, and
fuel tank filler cap)
N00941300173
Check these regularly for damage or leaks in the fuel lines and
connections. Check the fuel tank filler cap for damage or loose-
ness. Pay special attention to the fuel lines closest to high heat
sources such as the exhaust manifold.
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.
