For a safer and more enjoyable trip, always check for the following:  Before starting the vehicle, make certain that you and all passengers are seated andwearing their seat
belts properly (with
children in the rear seat, in appropriate restraints), and that all the doors arelocked.
 Move the driver’s seat as far backward as possible, while keeping good visibility,and good control of the steering wheel, brakes, accelerator, and controls. Check the instrument panel indicators and multi-information display for any possible prob- lem.  Similarly, the front
passenger seat should
also be moved as fa
r back as possible.
 Make sure that infants and small children are properly restrained in accordance with all laws and regulations.
Check these by selectin
g the defroster mode,
and set the blower switch on high. You should be able to feel the air blowing against thewindshield. Refer to “Defrosti
ng or defogging (wind-
shield, door windows)” on page 7-6, 7-10,7-17. Check all the tires for heavy tread wear or uneven wear patterns. Look for stones, nails, glass, or other objects
stuck in the tread. Look
for any tread cuts or
sidewall cracks. Check
the wheel nuts for tightness, and the tires (including spare tire) for proper pressure.
WA R N I N G If a floor mat is the
wrong size or is not
properly installed, it can interfere with theoperation of the pedals. Interference withthe pedals can cause unintended accelera- tion and/or increase
d stopping distances
resulting in a cras
h and injury. Always
make sure the floor mat does not interfere with the accelerator or brake pedal. Always use the retaining clip on the driver’s floorboard to secure the floor mat. Always install the mat with the correct side facing down. Never install a second mat over or under an existing floor mat. Do not use a floor mat designed for another model vehicle even if it is aMitsubishi genu
ine floor mat.
Before driving, be sure to check the fol- lowing:• Periodically check that the floor mat isproperly secured with the retaining clips. If you remove the fl
oor mat while clean-
ing the inside of you
r vehicle or for any
other reason, always
check the condition
of the floor mat afte
r it has been rein-
stalled.• While the vehicle is stopped with theengine off, check that
the floor mat is not
interfering with the pedals by depressing the pedals fully.

Your vehicle’s radio receives both AM and FM stations. The quality of your reception is affected by distance, obstacles, a
nd signal interference.
FM signals do not foll
ow the earth surface
nor are they reflected by the upper atmo- sphere. For this reason,
FM broadcasts cannot
be received over long di
stances. AM signals
follow the earth’s surfa
ce and are reflected by
the upper atmosphere. For this reason, AM broadcasts can be rece
ived over longer dis-
tances. Because of the limite
d range of FM signals
and the way FM waves transmit, you may experience weak or fading FM reception.When the broadcast is blocked by mountains or similar obstructions,
reception ca
n be dis-
turbed.
WA R N I N G Operating the CD player in a manner other than specifically instructed hereinmay result in hazardous radiation expo-sure. Do not remove the cover and attempt to repair the CD playe
r by yourself. There
are no user serviceable parts inside. Incase of malfunction,
contact an authorized
Mitsubishi Motors dealer or a repair facil- ity of your choice.

The electrolyte level
must be between the
limits shown on the outside of the battery. Fillit with distilled water as needed. The inside of the battery is divided into several compart- ments. Take the cap off of each compartmentand fill to the mark. Do not fill above the top line because a spill during driving could cause damage.
N00901600060
The battery is weaker in cold temperatures. This has to do with its chemical and physical properties and is why a very cold battery,especially one with a lo
w charge, will have a
hard time starting your vehicle. It is recommended that you have your batteryand charging system checked by an autho- rized Mitsubishi Motors dealer or a repair facility of your choice before the start of coldweather. If necessary, have it charged. This will provide more relia
ble starting, and longer
battery life.

It is important to fami
liarize yourself with the
following terms:
 Cold tire pressure: • The measured pressure after the vehiclehas been parked for
at least three hours,
or • The measured pressure when the vehicleis driven less than 1 mile (1.6 km) after having been parked for three hours.
 Maximum pressure: the maximum per- missible cold tire inflation pressure for this tire.  Recommended inflation pressure: the inflation pressure for optimum tire perfor- mance. Intended outboard sidewall: • The sidewall that
contains a whitewall,
bears white lettering or bears manufac-turer, brand, and/or model name molding that is higher or deeper than the same molding on the other sidewall of the tire,or • The outward facing sidewall of an asym- metrical tire that has a particular sidethat must always face outward when mounted on a vehicle.
 Passenger car tire: a tire intended for use on passenger cars,
multipurpose passen-
ger vehicles, and trucks
that have a gross
vehicle weight rating (GVWR) of 10,000pounds or less.
• If electrolyte gets on plastic parts or other 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 with plenty of water.• If electrolyte gets on your hands orclothes, rinse thoroughly with water. Ifelectrolyte 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 orworking 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, terminals 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 washingwith a solution of baking soda and water. Grease the posts and cl
amps after cleaning or
tightening them.WA R N I N G
 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
