7Battery
N00939100725
The vehicle battery is installed in the trunk behind a panel.
The condition of the battery is very important for quick starting
and to keep the vehicle’s electrical system working properly.
Be sure to have an authorized Mitsubishi Motors dealer check
the battery.
During cold weatherThe battery is weaker in cold temperatures. This has to do with
its chemical and physical properties and is why a very cold bat-
tery, especially one with a low charge, will have a hard time
starting your vehicle.
It is recommended that you have your battery and charging sys-
tem checked by an authorized Mitsubishi Motors dealer before
the start of cold weather. If necessary, have it replaced.Disconnection and connectionTo disconnect the battery cable, stop the engine. Disconnect the
negative (-) terminal first, then the positive (+) terminal. To
reconnect the battery, first connect the positive (+) terminal and
then the negative (-) terminal, before starting the vehicle.
WA R N I N G
!
Be sure to have an authorized Mitsubishi Motors
dealer charge the battery. Do not charge the battery
yourself, as it should only be charged after first
being removed from the vehicle.
In addition, never remove the battery label, upper
cover, exhaust tube, or pipe. Flammable gases may
leak and explode.
WA R N I N G
!
Never disconnect the battery while the engine is run-
ning, or you could damage the vehicle’s electrical
parts.
Never short-circuit the battery. This could cause it
to overheat and be damaged.
Keep sparks, cigarettes, and flames away from the
battery because the battery could explode.

Snow tires
N00940000359
In some areas of the country, snow tires are required for winter
driving. If snow tires are required in your area, you must
choose snow tires of the same size and type as the original tires
provided with your vehicle. Snow tires should also be installed
on all four wheels. Otherwise your safety and vehicle handling
can be reduced.
Even where laws may permit it, snow tires should not be oper-
ated at sustained speeds over 75 mph (120 km/h).Tire chains
N00940100015
Clutch pedal free play
(if so equipped)
N00940200087
To check the clutch pedal free play (A), turn off the engine and
press the pedal until you feel resistance.
Clutch pedal free play:
.2 to .4 inch (4 to 9 mm)
CAUTION
!
If flange nuts are used on your vehicle, change to
tapered nuts when using snow tires with steel
wheels.
Only Mitsubishi Motors genuine 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.
CAUTION
!
Tire chains cannot be used on your vehicle. The
clearance between the chains and the body is not
sufficient to allow proper clearance, and the vehicle
body might be damaged.

7 Emission-control system maintenance
N00940800201
Your vehicle is equipped with an emission-control system that
meets all the requirements of the U.S. Environmental Protec-
tion Agency and Environment Canada. The emission-control
system is made of:

a positive crankcase ventilation system

an evaporative emission-control system

an exhaust emission-control system
The maintenance services listed in the “WARRANTY AND
MAINTENANCE MANUAL” must be performed at the times
or mileages listed to keep the emission-control system working
properly. These, and all the other “general” maintenance ser-
vices listed in this manual, need to be performed to keep your
vehicle running properly and reliably.
You may need more frequent maintenance if you drive your
vehicle in harsh conditions such as dusty areas or do a lot of
start-and-stop driving.
To be sure the emission-control system works properly, have
your vehicle inspected and maintained by an authorized Mit-
subishi Motors dealer or a repair facility of your choice follow-
ing the schedule in the “WARRANTY AND MAINTENANCE
MANUAL”.
You should also have an inspection and service any time you
suspect a malfunction.
NOTE
To meet government regulations and promote cleaner air,
your vehicle is equipped with an onboard diagnostic sys-
tem (OBD). The engine electronic control module that
controls OBD functions stores various data (especially
about 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.

Exhaust system
N00942200108
The best way to keep carbon monoxide gas from entering
inside your vehicle is to have the engine exhaust system prop-
erly serviced.
Have a competent mechanic inspect the complete exhaust sys-
tem and nearby body areas for broken, damaged, deteriorated,
or mispositioned parts if you notice any of the following:

A change in the sound of the exhaust system

The smell of exhaust fumes inside the vehicle

The underside or rear of the vehicle is damaged
Also check the exhaust system each time the vehicle is raised
for lubrication, oil changes, or required service. Any open
seams or loose connections could let dangerous exhaust fumes
seep into the luggage compartment and passenger compart-
ments. Check for any of the following conditions:
Check for holes or exhaust gas leaks caused by corrosion
or damage.

Check the joints and connections for looseness or exhaust
gas leaks.

Check the rubber hangers and brackets for damage.
Hood lock release mechanism and safety catch
N00942500042
The hood lock release mechanism and hood safety catch should
be checked, cleaned, and oiled when needed for easy move-
ment and to stop rust and wear. Use Multipurpose Grease
NLGI Grade 2 sparingly for all sliding parts of the hood latch
and release lever. Work the grease into the hood lock mecha-
nism until all the movable surfaces are covered.
Also, put a light coat of the same grease on the safety catch
wherever moving parts touch.
WA R N I N G
!
Carbon monoxide gas from your vehicle’s exhaust is
poisonous. Breathing these fumes can cause uncon-
sciousness or death.

CAUTION
!
When washing the underside of your vehicle or the
wheels, wear a pair of gloves to protect your hands.
This vehicle is equipped with a high performance
brakes. Wash the wheels frequently to remove brake
dust. The dust will be difficult to remove if left on
the wheels for too long.
If your vehicle has rain sensor wipers, place the
wiper switch lever in the “OFF” position to deacti-
vate the rain sensor before washing the vehicle. Oth-
erwise, the wipers will operate in the presence of
water spray on the windshield and become damaged
as a result.
Never spray or splash water on the electrical parts
in the engine compartment. This may damage them.
Be careful also when washing the underbody. Do not
spray water into the engine compartment.
Avoid automatic car washers that use rotating
brushes. These brushes may scratch the paint sur-
face and make it dull.
Scratches are more noticeable on darker colored
vehicles.

Some hot water washing equipment uses high pres-
sure and heat to clean your vehicle. This heated
water may damage your vehicle’s resin parts. It can
flood the interior of the vehicle. Therefore, be sure
of the following:
• Keep the washing nozzle at least 20 inches (50 cm)
away from the vehicle body.
• When washing around the door glass, hold the
nozzle at a distance of more than 20 inches (50 cm)
and at right angles to the glass surface.

When using high-pressure water to wash a vehicle
equipped with the F.A.S.T.-key system, keep the
water from spraying on the open button on the
trunk. This could cause the trunk to open and flood
the inside of the trunk.
Make sure to do the following when using an auto-
matic car wash, with help from either this manual or
the car wash operator, to avoid damaging your vehi-
cle:
• Fold the outside rear-view mirrors.
• Remove the antenna.
• If your vehicle is equipped with rear spoiler, check
with the car wash operator before using the car
wash.
• If your vehicle has rain sensor wipers, place the
wiper switch lever in the “OFF” position to deacti-
vate the rain sensor.CAUTION

color. In this case, wipe it off using lukewarm water and a soft
cloth or chamois. Chrome parts
N00946400010
To prevent spots and corrosion of chrome parts, wash with
water, dry thoroughly, and apply a nonabrasive automotive
wax. If the chrome is severely damaged or pitted, use a com-
mercially available chrome polish.
CAUTION
!
Do not use a scrubbing brush or other rough scrub-
ber as these may damage the plastic surface.
Do not use wax containing compounds (polishing
powder) which may damage the plastic surface.
Do not let the plastic parts get soiled with gasoline,
oil, brake fluids, engine oils, greases, paint thinner,
and sulfuric acid (battery electrolyte). These fluids,
etc., may crack, stain or discolor the plastic parts.
If any of these get on the plastic parts, wipe them up
with a soft cloth or chamois and a mild solution of
soap and water. Then rinse them immediately with
water.
