NOTE
It is recommended that your vehicle be stored at tempera-
tures below 77 °F (25 °C) to help maximize the life of the
main drive lithium-ion battery.Decrease of battery capacity
N01205500012

The capacity of the lithium-ion battery used as the main
drive lithium-ion battery on your i-MiEV, like other com-
monly used lithium ion batteries, will decrease according
to time and usage. This type of decrease in battery capac-
ity is normal, and is not indicative of any defect or failure
in your main drive lithium-ion battery. As the main drive
lithium-ion battery capacity decreases, the initial cruising
range of the vehicle will similarly decrease.
WA R N I N G
!
The main drive lithium-ion battery is a sealed high
voltage battery and has no user serviceable parts.
• To avoid severe burns and/or electrical shock that
may result in serious injury or death, never
attempt to detach the main drive lithium-ion bat-
tery from the vehicle or try to disassemble it.
• Never attempt to dispose or recycle the main drive
lithium-ion battery by yourself. Consult with a
certified i-MiEV dealer, when the main drive lith-
ium-ion battery is disposed or recycled.
• Never attempt to use the main drive lithium-ion
battery for any other purpose.CAUTION
!
To help prevent damage to the main drive lithium-
ion battery, follow the instructions described below.
Failure to do so can result in damage to the main
drive lithium-ion battery that will not be covered by
the main drive lithium-ion battery warranty.
• Do not leave your vehicle with the energy level
gauge (Refer to “Energy level gauge” on page 3-
69) showing 0 bars.
• Repeatedly performing quick charging can reduce
battery capacity. Regular charging is recom-
mended unless quick charging is necessary.

Do not store your vehicle at ambient temperatures
above 131 °F (55 °C) for over 24 hours, or below
-13 °F (-25 °C) for over 7 days. The temperatures
may damage the main drive lithium-ion battery.

Mitsubishi Motors estimates that after 5 years, the capac-
ity of the main drive lithium-ion battery provided with
your vehicle will be approximately 80% of the original
capacity. After 10 years, the capacity should be approxi-
mately 70% of the original capacity. These are only esti-
mates, and the actual capacity of your vehicle battery over
time will depend on a variety of factors including how
your vehicle is used, stored and charged. Factors that can
adversely affect battery capacity over time include fre-
quent driving using aggressive acceleration/deceleration,
repeated frequent use of the quick charger, and opera-
tion/storage in extreme temperature environments.

The main drive lithium-ion battery has a limited service
life, and when its charging capacity falls, owners should
bring their vehicle to a certified i-MiEV dealer for inspec-
tion and possible battery replacement.

For details regarding the warranty coverage for the main
drive lithium-ion battery, refer to the Warranty and Main-
tenance Manual.NOTE
To help maintain the capacity of the main drive lithium-
ion battery, the following are recommended:
• Fully charge the vehicle by regular charging every 2
weeks.
• Do not repeat charging when the main drive lithium-ion
battery is at or near full charge.
Cruising range
N01200400016
The distance you can drive the vehicle (cruising range)
depends on a number of factors including available charge,
weather, temperature, usage, battery age, topography, and driv-
ing style. When the main drive lithium-ion battery is new, the
estimated cruising range with a fully charged main drive lith-
ium-ion battery is 62 miles (100 km) based on the EPA labora-
tory test commonly called the combined range. Your actual
range can vary, either initially or as the battery ages and with
use over time.
As the main drive lithium-ion battery capacity decreases, the
cruising range of the vehicle will similarly decrease. Refer to
“Decrease of battery capacity” on page 1-4.NOTE
Since cooling or heating consumes power from the main
drive lithium-ion battery, operation of these functions will
reduce the cruising range.

Put the selector lever in the “B” (REGENERATIVE
BRAKE MODE) or “Eco” (ECO MODE) position
according to the road condition. Using appropriate regen-
erative braking can help increase the cruising range. Refer
to “Regenerative braking” on page 1-3.

1 Modifications to and racing of your vehicle
N01200500017
This vehicle should not be modified with non-Mitsubishi
Motors genuine parts. Mitsubishi Motors designs and manufac-
tures high quality vehicles with an emphasis on safety and
durability. Modifications using non-Mitsubishi Motors genuine
parts may affect the performance, safety and/or durability of
your vehicle, and may violate applicable state and/or federal
regulations.
DAMAGE OR PERFORMANCE PROBLEMS RESULT-
ING FROM MODIFICATIONS TO OR RACING OF
YOUR VEHICLE ARE NOT COVERED UNDER WAR-
RANTY.
Examples of modifications to your vehicle that can cause dam-
age or performance problems include the following:

Failure to use Mitsubishi Motors genuine parts

Failure to use required fluids (refer to “Refill capacities”
on page 9-10)

Failure to use proper size tires and wheels

Modification of the suspension, electric motor, drive train,
batteries (main drive lithium-ion battery and 12V starter
battery), charging systems or electrical wiring systems

Modification of any onboard computer/control module,
including reprogramming, or replacing/adding chips to
any onboard computer/control module
Review the Warranty and Maintenance Manual for further
details regarding warranty coverage.
Installation of accessories
N01200600018

The installation of accessories, optional parts, etc., should
only be carried out within the limits prescribed by law in
the driving area and in accordance with the guidelines and
warnings contained within the documents accompanying
this vehicle.
Only Mitsubishi Motors approved accessories should be
fitted to your vehicle.

Improper installation of electrical parts could cause fire.
Refer to the “Modification/alterations to the electrical sys-
tems” section within this owner’s manual.

Tires and wheels which do not meet specifications must
not be used.
Refer to the “Specifications” section for information
regarding wheel and tire sizes.
CAUTION
!
Before any electrical or electronic accessories are
installed, consult a certified i-MiEV dealer.

!
If you choose to use a cellular phone while driving,
you must not allow that usage to distract you in the
safe operation of your vehicle. Anything, including
cellular phone usage, that distracts you from the
safe operation of your vehicle increases your risk of
an accident.
Refer to and follow all local laws in your area
