 Check the 12V starter battery, including terminals and cables. During extremely cold weather, the 12V starter battery willnot be as strong and its power level may drop. Before driving the vehicle, check to see ifthe headlights are as bright as normal. Charge or replace th
e 12V starter battery
if necessary. During extreme cold weather, it is possible that a very low 12V starter battery
could freeze.
 Check the antifreeze. If there is not enough coolant because of aleak, add high-quality ethylene glycol antifreeze and water. Use Mitsubishi Motors Genuine Super Long Life CoolantPremium or an equivalent. The recom- mended blend is about 50 % water and 50 % anti-freeze. Use a higher concentration(not over 60 %) when the outside temper- ature is -31 °F (-35 °C) or lower. When the electric motor unit is working very hard (for example,
during mountain driv-
ing and/or when the outside temperatureis high), use a 50 % concentration. This blend will provide adequate protection from corrosion and boiling.

All the parts of the brake system are critical to safety. Have the vehicle serviced by a certi- fied i-MiEV dealer at regular intervalsaccording to the “WARRANTY AND MAINTENANCE MANUAL”.
Check the brake system while driving at a low speed immediately
after starting, espe-
cially when the brakes are wet, to confirmthey work normally. A film of water can be formed on the brake discs and prevent normal braking after driv-ing in heavy rain or through large puddles, or after the vehicle is washed. If this occurs, dry the brakes out by drivi
ng slowly while lightly
depressing the brake pedal. On snowy roads, ice can form on the braking system, making the brakes less effective. While driving in such
conditions, pay close
attention to preceding and following vehicles and to the condition of the road surface. From time to time, lightly depress the brake pedaland check how effective the brakes are. Put the selector lever to “B” (REGENERA- TIVE BRAKE MODE) or “ECO” (ECO MODE) position according to the grade of the slope and vehicle sp
eed. This will allow

WA R N I N GThe 12V starter batter
y gives off explosive
hydrogen gas. Any spark or flame cancause the 12V starter battery to explode, which could cause serious injury or death. Always wear protecti
ve clothes and a face
mask when working wi
th your 12V starter
battery, or let a skil
led mechanic do it.
WA R N I N GNever open the coolan
t reservoir cap while
it is hot. You could be seriously burned.

It is very importa
nt to know how much
weight your vehicle can carry. This weight is called the vehicle capacity weight andincludes the weight of all occupants, cargo and non-factory-installed options. The tire and loading information placard located onthe driver’s door sill of your vehicle will show how much weight it may properly carry. It is important to famil
iarize yourself with the
following terms before loading your vehicle:  Vehicle maximum load on the tire: load on an individual tire that is determined bydistributing to each axle 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 curbweight, accessory weight, and normal occupant weight and dividing by two.
 Maximum loaded vehi
cle weight: the sum
of -(a) Curb weight; (b) Accessory weight; (c) Vehicle capacity weight; and(d) Production options weight.  Curb weight: the weight of a motor vehi- cle with standard equipment including themaximum capacity of
oil, and coolant.
 Accessory weight: the combined weight (in excess of those st
andard items which
may be replaced) of automatic transmis- sion, power steering, power brakes, powerwindows, power seats,
radio, and heater,
to the extent that these items are available as factory- installe
d equipment (whether
installed or not).  Vehicle capacity weight: the rated cargo and luggage load plus 150 lbs (68 kg)
*
times the vehicle’s designated seating capacity.  Production options weight: the combined weight of those installed regular produc- tion options weighing over 5 lbs (2.3 kg) in excess of those standard items whichthey replace, not prev
iously considered in
curb weight or accessory weight, includ- ing heavy duty brakes,
ride levelers, roof
rack, heavy duty battery, and special trim.  Normal occupant weight: 150 lbs (68 kg)
*
times the number of specified occupants.(In your vehicle the number is 2)
 Occupant distribution: distribution of occupants in a vehicle as specified. (Inyour vehicle the distribution is 2 in front seat)

The tire and loading information placard is located on the driver’s door sill. This placard shows the maximum number of occupants permitted to
ride in your vehicle as
well as “the combined
weight of occupants
and cargo” (C), which
is called the vehicle
capacity weight. This
placard also tells you

WA R N I N GNever overload your ve
hicle. Overloading
can damage your vehicl
e, adversely affect
vehicle performance, including handlingand braking, cause tire failure, and result in an accident.
* : 150 lbs (68 kg) is the weight of one per- son as defined by U.
S.A. and Canadian
regulations.

The coolant level in th
is reservoir should be
kept between the “F (FULL)” and the “L(LOW)” marks when measured while the electric motor is cold. If necessary, add cool- ant. Refer to “To add coolant” on page 9-6.

Mitsubishi Motors Genui
ne Coolant provides
excellent protection against corrosion and rust formation on all metals, including alumi- num.
If you need to add coolant often, the cooling system should be pressure-tested for leaks.Take your vehicle to a certified i-MiEV dealer for testing.
N00955800010
The reservoir cap (E) must be tightly sealedto prevent losing coolant which may result in electric motor or nearby parts of the roomunder the hood damage. Only use a Genuine Mitsubishi Parts rese
rvoir cap, or an
approved equivalent.
N00955700019
 Do not overfill the reservoir.  Your vehicle uses a special reservoir cap that stays sealed and keeps the pressure inthe reservoir below the allowable pres- sure. If you need to change the cap, use the exact same kind.  Check the coolant freeze point in the radi- ator with the proper gauge, and only when it is safe. If you add antifreeze, the con-tents of the reservoi
r must be protected
against freezing.  Keep the front of the radiator and con- denser clean.
To add coolant Use “Mitsubishi Motors
Genuine Super Long
Life Coolant Premium”
or an equivalent
*.

ity ethylene glycol
based non-silicate, non-amine, non-nitrate and non-borate coolant with long life hybrid organic acid technologyFULL LOW
CAUTION Do not use alcohol or
methanol antifreeze or
any coolants that c
ontain them. Using the
wrong antifreeze can corrode aluminumparts.  The required concentration of anti-freeze dif- fers depending on the
expected ambient tem-
perature. Above -31 °F (-35 °C):
50 % concentration
of anti-freeze Below -31 °F (-35 °C): 60 % concentration of anti-freezeYou can check the concen
tration level with a
gauge from an automotive supply store, or a certified i-MiEV dealer or service station cancheck it for you. Do not use water to adjust the concentration of coolant.  Do not top off the tank with plain water only. Water by itself boils at a lower temperature and does not stop rust or freezing. If the water freezes, it will
damage your cooling
system. Do not use tap water. It can cause corrosion and rust.
Reservoir cap
WA R N I N G Wait for the electric motor to cool down before opening the re
servoir cap. Other-
wise hot steam or bo
iling coolant could
spray up from the re
servoir and scald you.
