It is very importa
nt to know how much
weight your vehicle can carry. This weight iscalled the vehicle capacity weight and includes the weight of
all occupants, cargo,
non-factory-installed options, if any, beingtowed. The tire and load
ing information plac-
ard located on the driver’s door sill of your vehicle will show how
much weight it may
properly carry. It is important to familiarize yourself with the following terms before
loading your vehicle:
 Vehicle maximum load on the tire: load on an individual tire th
at is determined by
distributing to each ax
le its share of the
maximum loaded vehicle weight and dividing by two.  Vehicle normal load on the tire: load on an individual tire that is
determined by dis-
tributing to each axle its share of the curb weight, accessory
weight, and normal
occupant weight and dividing by two.  Maximum loaded vehicle weight: the sum of -(a) Curb weight; (b) Accessory weight; (c) Vehicle capacity weight; and(d) Production options weight.
Parking with the engine run- ning
WA R N I N G Leaving the engine ru
nning risks injury or
death from accidentally moving the gear-shift lever (manual transaxle) or the selec- tor lever (CVT) or from the accumulation of toxic exhaust fumes in the passengercompartment.
Where you park
WA R N I N G Do not park your vehicle in areas where combustible materials
such as dry grass or
leaves can come in contact with a hotexhaust, since a fire could occur.
Do not keep the steering wheel fully turned for a long time When leaving the vehicle Loading information
WA R N I N G Never overload your ve
hicle. Overloading
can damage your vehicle, adversely affectvehicle performance, including handling and braking, cause tire failure, and result in an accident.

Only use the designated positions shown in the illustration.
N00937400450
The catalytic converter requires you to use unleaded fuel only. Leaded gasoline willdestroy the emission-control effectiveness of the converter. Normally, the
catalytic converter does not
require maintenance. Ho
wever, it is important
to keep the engine properly tuned for the con- verter to continue to work properly.
To reduce the possibili
ty of catalytic con-
verter damage:  Use UNLEADED GASOLINE ONLY of the type of recommended in the “Fuel selection”.  Do not drive with an extremely low fuel level. Running out of gas could damage the catalytic converter.  Do not try to start the engine by pushing or towing the vehicle. If the battery is weak or run down, use jumper cables to properly start the engine. Do not idle the engine with any spark plug wires disconnected or
removed, such as
when performing diagnostic tests. Do not idle the engine for a long time if it is idling roughly or otherwise obviously malfunctioning. To prevent the catalytic converter from being damaged from unburned gas, do not race the engine when stopping the engine.
If your vehicle is raised with a garage jack *- Front of the vehicleWA R N I N G Set a garage jack only at the position shown here. If the gar
age jack is set a
wrong position, it could damage your vehicle and/or your
vehicle might fall
from the jack causing injury or death.
Never use the rear suspensions as a jack-ing point.
 Do not use the jack on a tilted or soft sur- face.Otherwise, the jack might slip and causepersonal injury. Always
use the jack on a
flat, hard surface. Before setting the jack, make sure there are no sand or pebblesunder the jack base.
Catalytic converter
CAUTION Damage to the catalytic
converter can result
if your vehicle is not
kept in proper operating
condition. If the engine
malfunctions or mis-
fires, or if your vehi
cle performance suffers,
have it serviced
promptly. Running your
vehicle when it is ove
rheated may result in
damage to the conve
rter and vehicle.
WA R N I N G
WA R N I N GDo not park or run your vehicle in areas where combustible materials such as drygrass or leaves can come
in contact with a
hot exhaust, since a fire could occur. Do not put undercoat paint on the cata- lytic converter.

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.

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.
