 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 abou
t 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 veryhard (for example, during mountain driv- ing and/or when the outside temperature is high), use a 50 %
concentration. This
blend will provide
adequate protection
from corrosion and boiling.

All the parts of the brake system are criticalto 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 confirm they work normally. A film of water can be formed on the brakediscs and prevent normal braking after driv- ing in heavy rain or through large puddles, or after the vehicle is washed. If this occurs, drythe brakes out by driving slowly while lightly depressing the brake pedal. On snowy roads, ice can form on the braking system, making the brak
es less effective.
While driving in such conditions, pay closeattention to preceding
and following vehicles
and to the condition of the road surface. From time to time, lightly
depress the brake pedal
and 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 ofthe slope and vehicle sp
eed. This will allow
effective use of the regenerative brake and prevent the service brake from overheating.If the brake pedal is continuously or fre- quently depressed on downhill roads, the ser- vice brake could overheat and the brake performance will be reduced.
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.
Braking When brakes are wet When driving in cold weather
When driving downhill
NOTE
 When the main drive lithium-ion battery level is full or nearly full, or the main drivelithium-ion battery temp
erature is too high or
too low, the regenerative braking force may be reduced. Refer to “Regenerative braking”on page 3-3.  If the red needle in the energy usage indica- tor does not move to the left of the neutral point (A) while the
accelerator pedal is
released, the regenerative brake will notwork. Refer to “Ener
gy usage indicator” on
page 5-37. In the such
case, before approach-
ing a long downhill
road, reduce speed to
prevent the service brake from overheating.

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”

The windshield washer fluid reservoir is under the hood. Check the washer fluid level at regular inter-vals and add washer fluid to reservoir if nec- essary. Open the reservoir cap and check the fluidlevel. When freezing weather is anticipated, flush out the water in the reservoir by operating the pump. Fill the reservoir with windshield anti-freeze (not radiator
antifreeze), and operate
the system for a few se
conds to flush out the
residual water.
N00938700261
The brake fluid level must be between the “MAX” and “MIN” marks on the reservoir. The brake fluid level fa
lls slightly with wear
of the brake pads, but
this does not indicate
any abnormality. The brake fluid in the master cylinder should be checked when doing other work under the hood. The brake system should also bechecked for leaks at the same time. If the brake fluid level falls markedly in a short length of time, it indicates a leak in thebrake system.
If this occurs, have the vehicle checked by a certified i-MiEV dealer. Use the recommended brake fluid conform- ing to DOT 3 or DOT 4. The reservoir capmust be tightly sealed
to keep dirt and water
out.
