The radiator cap must be sealed tight to pre-vent losing coolant, which may result inengine damage. Only use a MitsubishiMotors Genuine Parts radiator cap, or anapproved equivalent.
Do not overfill the reserve tank.Your vehicle uses a
special radiator cap
that stays sealed and lets the coolant flowfrom the reserve tank back to the radiatorwhen the engine cools down. If you needto change the cap, use the exact samekind.Check the coolant freeze point in the radi-ator with the proper gauge, and only whenit is safe. If you add antifreeze, the con-tents of the reserve ta
nk must be protected
against freezing.Keep the front of the radiator and con-denser clean.If the engine coolan
t temperature does not
rise after the engine
is warmed-up, take
your vehicle to an au
thorized Mitsubishi
Motors dealer or a repair facility of yourchoice to have the thermostat checked,and replaced if necessary.

The automatic transaxl
e should be maintained
and serviced by an authorized MitsubishiMotors dealer or a repair facility of yourchoice to obtain the
best performance and
longest life. It is impor
tant that the transaxle
fluid is kept at the correct level.The fluid level should be checked when thebar graph for the engine coolant temperaturedisplay on the multi-information displayshows the engine is warmed up and the fluidin the transaxle is heated to its normal work-ing temperature. Driving with the wrong fluidlevel will rapidly wear
out the transaxle and
destroy the fluid.1. With the brake pedal fully depressed andthe engine idling,
select each gear
momentarily, ending with the selectorlever in the “P” (PARK) position.
2. The fluid level should be at the HOTmark, but never above the HOT markwhen the engine is warmed up. Add ordrain fluid to get to the correct level.3. Make certain that the dipstick cap isinstalled properly to keep dirt and waterout of the transaxle.
Use only “Mitsubishi Motors Genuine ATF-J3” transaxle fluid to
ensure optimum trans-
axle performance.

Do not fill above the t
op line because a spill
during driving could cause damage.The battery is weaker in cold temperatures.This has to do with its chemical and physicalproperties and is why a very cold battery,especially one with a low charge, will have ahard time starting your vehicle.It is recommended that you have your batteryand charging system checked by an autho-rized Mitsubishi Motors dealer or a repairfacility of your choice before the start of coldweather. If necessary, have it charged. Thiswill provide more relia
ble starting, and longer
battery life.To disconnect the battery cable, stop theengine. Disconnect the
negative (-) terminal
first, then the positive (+) terminal. To recon-nect the battery, first
connect the positive (+)
terminal and then the negative (-) terminal,before starting the vehicle.During cold weather Disconnection and connection

Open the terminal cover (A) before discon-necting or connecting
the positive (+) termi-
nal of the battery.
Loosen the nut (B) and then disconnect thebattery cable from the positive (+) terminal.WA R N I N GNever disconnect the battery while theengine is running, or you could damagethe vehicle’s electrical parts.Never short-circuit the battery. This couldcause it to overheat and be damaged.Keep sparks, cigarettes, and flames awayfrom the battery because the battery couldexplode.Electrolyte (battery acid) is made of corro-sive diluted sulfuric acid. If it spills onnearby parts, it can crack, stain, or dis-color them. And if it gets on your skin orin your eyes, it can cause burns or blind-ness. Please observe the following han-dling instructions:NOTE
• If electrolyte gets on plastic parts orother 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 withplenty 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, orhave a skilled automobile technician do it.If you are quick-ch
arging your battery,
first disconnect the battery cables.In order to prevent a
short-circuit, be sure
to disconnect the negative (-) terminalfirst, and reconnect it last.If the electrolyte level
is very low, have the
battery checked at an
authorized Mitsubi-
shi Motors dealer or
a repair facility of
your choice.Battery posts, terminals and related acces-sories contain lead

da. The emission-con-
trol system is made of:a positive crankcase
ventilation system
an evaporative emis
sion-control system
an exhaust emission-control system
To be sure the emissi
on-control system works
properly, have your vehicle inspected andmaintained by an authorized MitsubishiMotors dealer or a repair facility of yourchoice. This should be done at the time ormileage specified in the “WARRANTY ANDMAINTENANCE MANUAL”.These, and all the other “general” mainte-nance services listed in this manual, need tobe performed to keep
your vehicle running
properly and reliably.You should also have an inspection and ser-vice any time you suspect a malfunction.

To meet government regulations and pro-mote cleaner air, your
vehicle is equipped
with an onboard dia
gnostic system (OBD).
The engine electronic control module thatcontrols OBD functions stores various data(especially a
bout the exhaust emissions).
This data will be erased if the battery cable isdisconnected, which c
ould make a rapid
diagnosis difficult.
Do not disconnect the
battery cable when the engine malfunctionindicator (“SERVICE ENGINE SOON” or“Check engine
light”) is ON.
