The 12V starter battery is weaker in cold tem- peratures. This has to do with its chemicaland physical propertie
s and is why a very
cold 12V starter battery, especially one with a
low charge, will have a hard time starting your vehicle.It is recommended that you have your 12V starter battery and charging system checked by a certified i-MiEV dealer before the startof cold weather. If necessary, have it charged. This will guarantee more reliable starting, and longer 12V starter battery life.
N00901701114
To disconnect the 12V starter battery cable,stop the electric motor.
Disconnect the nega-
tive (-) terminal first, then the positive (+) ter- minal. To reconnect th
e 12V starter battery,
first connect the positi
ve (+) terminal and
then the negative (-) terminal, before starting the vehicle.
 After checking the 12V starter battery electrolyte level, make sure the caps arefitted securely. If any of the caps cannot be re-secured to the 12V starter battery, replace the 12Vstarter battery. Electrolyte (battery acid) is made of corro- sive diluted sulfuric acid. If it spills on nearby parts, it can crack, stain, or dis- color them. And if gets on your skin or inyour eyes, it can cause burns or blindness. Please observe the following handling instructions:• If electrolyte gets on plastic parts orother nearby parts, wi
pe it off with a soft
cloth 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. If electrolyte gets in your eyes, flush them with water immediat
ely and get immedi-
ate medical attention.

Disconnection and connection
WA R N I N G Never disconnect the
12V starter battery
while the electric motor unit is running, or you could damage the
vehicle’s electrical
parts.  Never short-circuit
the 12V starter bat-
tery. This could cause it to overheat and be damaged.  Keep sparks, cigarette
s, and flames away
from the 12V starter battery because the 12V starter battery could explode.
 When installing the
12V starter battery,
start connection with the positive (+) ter-minal. If connection is started from thenegative (-) terminal,
sparks will occur if
the positive (+) termin
al touches any other
parts, and this may cause the 12V starterbattery to explode.NOTE
 Remove the 12V starte
r battery upper cover
before disconnecting the terminal of 12V starter battery. Refer to “Removing and installing the 12V st
arter battery upper
cover” on page 9-8.  Open the terminal cover (A) before discon- necting or connecting the positive (+) termi- nal of the 12V
starter battery.
 Loosen the nut (B), and then disconnect the 12V starter batt
ery cable from the positive
(+) terminal.WA R N I N G

It is important to familiarize 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 inflation pressure: the maxi- mum permissible cold
tire inflation pres-
sure for this tire.  Recommended inflation pressure: the inflation pressure for optimum tire perfor- mance.
WA R N I N G Open doors and wind
ows in any closed
space where you may be charging orworking with the 12V starter battery.  Always wear protective clothing and gog- gles when working wi
th the 12V starter
battery, or have a sk
illed automobile tech-
nician do it.  If you are quick-charging your 12V starter battery, first disconnect the 12V starter 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
12V starter battery checked at a certified i-MiEV dealer. 12V starter battery te
rminals and related
accessories contain
lead and lead com-
pounds. Wash hands after handling. CAUTION When replacing the
12V starter battery,
remove the connected
positive (+) and nega-
tive (-) terminals after turning the electric motor switch to the “LOCK” position andwaiting at least 1 minut
e. If the 12V starter
battery terminal is removed just after the electric motor switch is turned to the “LOCK” position, this
may cause damage to
components of the electric motor unit.
NOTE
 Before cleaning the 12V starter battery, tighten all the filler port
caps to keep dirt and
moisture out.  Check each 12V starter battery terminal for corrosion. If necessary, clean the terminalswith a solution of baking soda and water. Grease the posts and cl
amps after cleaning or
tightening them.  Check to see that the 12V starter battery is securely installed and
cannot be moved. Also
check each terminal for tightness.  If you will not be driv
ing your vehicle for a
long period of time, re
move the 12V starter
battery and store it in a place where the 12V starter battery fluid wi
ll not freeze. Memory
data for settings made by the user may be erased when the 12V starter battery is removed. If this happens, reset the settingsagain using the releva
nt procedures. The
12V starter battery
only should be stored
with a full charge.
Tires
WA R N I N G Driving with tires that are worn, damaged or improperly inflated is dangerous.These type tire conditions will adversely affect vehicle performance. These type tire conditions can also cause atread separation or blowout which may result in an accide
nt causing serious
injury or death. Tires degrade over ti
me with age even
when they are not being used. It is recom-mended that tires ove
r 6 years generally
be replaced even if
damage is not obvious.

The treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified government test course
. For example, a tire
graded 150 would wear one and one-half (11/2) times as well on the government course
as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart signifi-cantly from the norm due to variations in driving habits, service practices and differ- ences in road characteristics and climate. The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire’s ability to stop on wet pavement as measured under contro
lled conditions on
specified government te
st surfaces of asphalt
and concrete. A tire marked C may have poor traction performance. The temperature grades are A (the highest), B and C, representing the ti
re’s resistance to the
generation of heat and it
s ability to dissipate
heat when tested u
nder controlled conditions
on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce
tire life, and excessive temperature can lead to sudden tire failure. The grade C corre-sponds to a level of
performance which all
passenger car tires must
meet under the Fed-
eral Motor Vehicle Safety Standard No. 109.Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Too little pressure increases flexing in the tire and can cause tire failure. Too muchpressure can cause a tire to lose its ability to cushion shock. Objects on the road and potholes could then cause tire damage thatmay result in tire failure.  Economy The wrong tire pressure can cause unevenwear patterns in the tire tread. These abnormal wear patterns will reduce the tread life, and the tire will have to be replaced sooner. Too little pressure also makes it harder forthe tire to roll, and this uses up more power.  Ride comfort and vehicle stability The superior riding
experience built into
your vehicle partly depends on the correct tire pressure. Too mu
ch pressure gives an
uncomfortable and ja
rring ride. Too little
pressure feels as if your vehicle is slow to respond.Unequal tire pressures can make steering your vehicle uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the placard attached to the sill of thedriver’s door. (Refer to “Tire and loading information plac- ard” on page 11-3.)The recommended inflation pressures should be used for the tires listed below.
Tire pressures should be checked, and adjusted if necessary, at least once a month.Pressures should be checked more often whenever weather temperatures change severely, becaus
e tire pressures change with
outdoor temperatures. The pressures listed on the placard are always
“cold inflation pres-
sure”.Cold inflation pressure is measured after the vehicle has been parked
for at least three
hours or is driven less than 1 mile (1.6 km)after having been parked for three hours. Cold inflation pressure must not go above the maximum values molded into the tire side-wall. After driving se
veral miles, your tire
inflation pressure may increase 14 to 41 KPA, 2 to 6 PSI from the cold inflation pressure.Do not let air out of the tires to get back to the specified cold pressure, or your tire pressure will be too low.You should also take the following safety pre- cautions:
 Keep your tires inflated to the recom- mended pressures. (See the tire and load-ing information placard attached to the sill of the driver’s door.)  Stay within the recommended load limits.  Make sure that the weight of any load in your vehicle is evenly distributed.  Drive at safe speeds.  After filling your tires to the correct pres- sure, check them for damage and air leaks. Be sure to reinstall the caps on the valve stems.

Replacing tires and wheels
CAUTION Avoid using different size tires and wheels from the ones listed, and avoid the combined use of different types
of tires and wheels.
Using different size or
type tires and wheels
may affect driving safety. Refer to “Tires and wheels” on page 11-6. Even if a wheel has the same rim size and offset as the specifie
d type of wheel, its
shape may prevent it
from being fitted cor-
rectly. Consult a certified i-MiEV dealer before
using wheels that you
have.

Tread wear indicators are built into the origi-nal equipment tires on your vehicle to helpyou know when your tires should be replaced. Many states have la
ws requiring that you
replace your tires at this point.These indicators are molded into the bottom of the tread grooves and will appear when the tire tread is worn down to 1/16 inch(1.6 mm). When the bands appear next to one another in two or more places,
replace your tires.

In some areas of the country, snow tires arerequired for winter driving. If snow tires arerequired in your area, you must choose snow tires of the same size
and type as the original
tires provided with your
vehicle. Snow tires
should also be
installed on all four wheels.
Otherwise your safety
and vehicle handling
can be reduced.Even where laws may permit it, snow tires should not be operated
at sustained speeds
over 75 mph (120 km/h).
 Only Mitsubishi Motors genuine wheels should be used, beca
use your vehicle is
equipped with a tire pr
essure monitoring sys-
tem. Use of another type of wheel risks air leaks and sensor damage, as it
will not be possible
to install the tire pressure sensor properly.
