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, because tire pressures change
with outdoor temperatures. The pressures listed on the placard
are always “cold inflation pressure”.
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 sidewall. After driving several 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 precautions:

Keep your tires inflated to the recommended pressures.
(See the tire and loading 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 pressure, check them
for damage and air leaks. Be sure to reinstall the caps on
the valve stems.

Replacing tires and wheels
N00939600427
Tire maintenance
N00939700170
The following maintenance steps are recommended:

Check tire pressures regularly.

Have regular maintenance done on the wheel balance and
front and rear suspension alignment.
Tread wear indicators
N00939800214
Tread wear indicators are built into the original equipment tires
on your vehicle to help you know when your tires should be
replaced. Many states have laws 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. NOTE
Tire wear indicators can have different marks and loca-
tions depending on the tire manufacturer.
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 9-9.
Even if a wheel has the same rim size and offset as
the specified type of wheel, its shape may prevent it
from being fitted correctly. Consult a certified
i-MiEV dealer before using wheels that you have.
Only Mitsubishi Motors genuine wheels should be
used, because your vehicle is equipped with a tire
pressure monitoring system.
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.

Tire rotation
N00939900518
Because the front and rear tires and wheels are not the same
size, do not rotate the front and rear tires.
Snow tires
N00940000359
In some areas of the country, snow tires are required for winter
driving. If snow tires are required 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 oper-
ated at sustained speeds over 75 mph (120 km/h).Tire chains
N00940100129
WA R N I N G
!
Rotating tires would compromise the stability and
drivability of the vehicle and could lead to a serious
accident.
CAUTION
!
If flange nuts are used on your vehicle, change to
tapered nuts when using snow tires with steel
wheels.
Only Mitsubishi Motors genuine wheels should be
used, because your vehicle is equipped with a tire
pressure monitoring system.
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.
CAUTION
!
Tire chains cannot be used on your vehicle. The
clearance between the chains and the body is not
sufficient to allow proper clearance, and the vehicle
body might be damaged.

If the free play is not within these limits, take your vehicle to a
certified i-MiEV dealer for adjustment.
Parking brake lever stroke
N00940400236
Check the parking brake lever travel occasionally. To check
this, pull the lever up slowly and count the number of clicks of
the ratchet.
Parking brake lever stroke:
6 to 7 notches
Also check to see if the lever stays gripped by the ratchet after
pulling.
WA R N I N G
!
Continued operation of the vehicle with the parking
brake lever out of adjustment may result in the vehi-
cle moving when unattended.

7Wiper blades
N00940700200
Check the wiper blades occasionally. Clean them regularly to
remove deposits of salt and road film. Use a sponge or cloth
and a mild detergent or non-abrasive cleaner to clean the blades
and glass areas.
Replace the blades if they continue to streak or smear.NOTE
Do not run the wipers on dry glass for a long time. This
wears out the rubber and can scratch the glass.During cold weatherIf the blades are frozen to the windshield or rear window, do
not operate the wipers until the ice has melted and the blades
are freed, otherwise the wiper motor may be damaged.NOTE
When replacing front wiper blade assembly with a wiper
blade for use in cold regions, it is necessary to adjust the
washer nozzle (A) spray positions. Always contact a certi-
fied i-MiEV dealer when replacing front wiper blade with
a wiper blade for use in cold regions.
When removing snow and frost, be careful not to damage
the washer nozzle which are attached to the wiper arm.

7 General maintenance
N00941500289
The next pages list the maintenance service recommended by
Mitsubishi Motors Corporation. In addition to the general
maintenance that needs to be performed at the times listed,
there are other parts which do not usually need regular mainte-
nance.
But, if any of these parts stops working properly, your vehicle
performance could suffer. Have these items checked if you
notice a problem with them.
See a certified i-MiEV dealer for assistance, if you have any
questions.Disc brake pads, rear drum brake linings and
rear wheel cylinders
N00941600033
Good brakes are essential to safe driving. Check the brake pads
and brake linings for wear and check the rear wheel cylinders
for leaks. For good braking performance, replace the brake
pads with the same type pads as the originals.Brake hoses
N00941700047
Brake hoses and tubing should be checked for:

Severe surface cracking, scuffing or worn spots. If the
fabric casing of the hose is showing through any cracks or
worn spots in the rubber hose cover, the hose should be
replaced. The brakes can fail if the hose wears through.

Improper installation may cause twisting, or wheel, tire or
chassis interference.
Ball joint, steering linkage seals and drive shaft
boots
N00941800077
Check the following parts for damage and grease leaks:

Ball joint boots of the front suspension and steering link-
age

Bellows on both ends of the drive shaftHood lock release mechanism and safety catch
N00942500114
The hood lock release mechanism and hood safety catch should
be checked, cleaned, and oiled when needed for easy move-
ment and to stop rust and wear. Use Multipurpose Grease
NLGI Grade 2 sparingly for all sliding parts of the hood latch
and release lever. Work the grease into the hood lock mecha-
nism until all the movable surfaces are covered.
Also, put a light coat of the same grease on the safety catch
wherever moving parts touch.

7For cold and snowy weather
N00942600131
Ventilation slotsThe ventilation slots in front of the windshield should be
brushed clear after a heavy snowfall so that the operation of the
heating and ventilation systems will not be impaired.WeatherstrippingTo prevent freezing of the weatherstripping on the doors, hood,
etc., they should be treated with silicone grease.Additional equipment (For regions where snow is
encountered)It is a good idea to carry a shovel or a short-handled spade in
the vehicle during the winter so that you can clear away snow
if you get stranded. A small hand-brush for sweeping snow off
the vehicle and a plastic scraper for the windshield, side and
rear window are also useful.
Fusible links
N00942700321
The fusible links will melt to prevent a fire if a large current
attempts to flow through certain electrical systems.
In case of a melted fusible link, see a certified i-MiEV dealer
for inspection and replacement.
For the fusible links, please refer to “Fuse load capacities” on
page 7-30.
WA R N I N G
!
Fusible links must not be replaced by any other
device. Failing to fit the correct fusible link may
result in fire in the vehicle, property destruction and
serious or fatal injuries at any time.
