2011 MITSUBISHI I-MIEV overheating

Inspection and maintenance
following rough road operation E00606700383
After
operating the vehicle in rough road condi-
tions, be sure to perform the following inspection
and maintenance procedures:
l Check that the vehicle has not been damaged
by rocks, gravel, etc.
l Carefully wash the vehicle with water.
Drive the vehicle slowly while lightly depress-
ing the brake pedal in order to dry out the
brakes. If the brakes still do not function prop-
erly, we recommend you to have the brakes
checked as soon as possible.
l Remove the insects, dried grass, etc. clog-
ging the radiator core.
l Check the inside of the vehicle. If water en-
try is found, dry the carpet etc.
l Inspect the headlamps, If the headlamp bulb
is flooded with water, we recommend you to
have it drained. Braking
E00607001830
All
the parts of the brake system are critical to safe-
ty. We recommend you to have the vehicle
checked at regular intervals according to the serv-
ice booklet. CAUTION
l
Avoid
driving habits that cause heavy
braking and never “ride” the brakes by
resting your foot on the brake pedal
while driving.
It causes brake overheating and fading.
Brake system
The
service brake is divided into two brake cir-
cuits. And your vehicle is equipped with power
brakes. If one brake circuit fails, the other is availa-
ble to stop the vehicle. If you should lose the pow-
er assist for some reason, the brakes will still work.
In these situations, even if the brake pedal moves
down to the very end of its possible stroke or re-
sists being depressed, keep depressing the brake ped-
al down harder and further than usual; stop driving
as soon as possible and have the brake system re-
paired. WARNING
l Do
not turn off the electric motor unit
while your vehicle is in motion. If you
turn off the electric motor unit while driv-
ing, the power assistance for the braking
system will stop working and your brakes
will not work effectively. WARNING
l If
the power assist is lost or if either
brake hydraulic system stops working
properly, have your vehicle checked im-
mediately.
Warning lamp
The
brake warning lamp illuminates to indicate a
fault in the braking system. Refer to “Brake warn-
ing lamp” on page 4-09.
When brakes are wet
Check the brake system while driving at a low
speed immediately after starting, especially when
the brakes are wet, to confirm they work normally.
A film of water can be formed on the brake discs
or brake drums and prevent normal braking after
driving in heavy rain or through large puddles, or
after the vehicle is washed. If this occurs, dry the
brakes out by driving slowly while lightly depress-
ing the brake pedal.
When driving downhill
It is important to take advantage of regenerative
braking by shifting to the “B” (BRAKE) position
while driving on steep downhill roads in order to
prevent the brakes from overheating. Starting and driving

If the ABS warning lamp and brake warning
lamp illuminate at the same time
The
ABS and brake force distribution function may
not work, so hard braking could make the vehicle
unstable.
Avoid hard braking and high-speed driving. Stop
the vehicle in a safe place and we recommend you
to have it checked.
NOTE
l The warning lamp may be illuminated when
the electric motor unit is started while the aux-
iliary battery voltage is low, but this is not an
ABS malfunction.
When the traction battery is charged, the aux-
iliary battery is charged at the same time, and
the warning lamp will go out.
If the warning lamp does not go out or illumi-
nates from time to time even after the battery
is charged, have the vehicle inspected at a
MITSUBISHI MOTORS Authorized Service
Point. After driving on icy roads
E00618800176
After
driving on snowy or icy roads, remove any
snow and ice which may have be left around the
wheels. Be careful not to damage the wheel speed
sensors (A) or the cables located at each wheel.
Front
Rear Electric power steering system
(EPS) E00629200079
The

electric power steering system (EPS) uses an
electric motor to assist the turning of the steering
wheel.
NOTE
l During repeated full-lock turning of the steer-
ing wheel (for example, while you are ma-
noeuvring the vehicle into a parking space),
a protection function may be activated to pre-
vent overheating of the power steering sys-
tem. This function will make the steering
wheel gradually harder to turn. In this event,
limit your turning of the steering wheel for a
while. When the system has cooled down,
the steering action will return to normal.
l If you turn the steering wheel while the vehi-
cle is stationary with the headlamps on, the
headlamps may become dim. This behaviour
is not abnormal. The headlamps will return
to their original brightness after a short while. Starting and driving

Connect one end of the other jumper cable to
the
negative (-) terminal of the booster bat-
tery, and the other end to the designated loca-
tion of the vehicle with the discharged bat-
tery at the point farthest from the battery. WARNING
l Make
sure you observe the following or-
der when connecting the cables: → →
→
l
Make sure you make connection to the
correct

designated location (as shown in
the illustration). If the connection is made
directly to the negative (-) side of the dis-
charged battery, flammable gases gener-
ated from the battery might catch fire
and explode. WARNING
l When
connecting the jumper cables, do
not connect the positive (+) cable to the
negative (-) terminal. Otherwise sparks
might cause explosion of the battery. CAUTION
l
Take
care not to get the jumper cable
caught in the cooling fan or other rotat-
ing part in the bonnet room or engine com-
partment.
l Use the proper cables suitable for the bat-
tery size to prevent overheating of the ca-
bles.
l Check the jumper cables for damage and
corrosion before use.
8. Start
the engine in the vehicle which has the booster battery, let the engine idle a few mi-
nutes, then start the electric motor unit in the
vehicle with the discharged battery.
9. Check that the ready indicator illuminates.

[When the ready indicator illuminates]
Stop

the engine of another vehicle, discon-
nect the cables in the reverse order and
charge the auxiliary battery for more than 30
minutes.
After the auxiliary battery is charged, contin-
ue the process from step 16.

[When the ready indicator does not illuminate]
Both the auxiliary battery and the traction bat-
tery have gone flat at the same time.
Charge the auxiliary battery and the traction
battery by the following procedures (from
steps 10 to 14).

10. Keep connecting the jumper cable to each ve- hicle, turn the electric motor switch of your
vehicle to the “LOCK” position.
NOTE l The jumper cable needs to be connected to
the auxiliary battery when you start charging
the traction battery because the on board
charger etc. operate with a power source of
auxiliary battery.
11. Charge the traction battery by regular charg- ing. (Refer to “Regular charging” on page
1-04.)
12. When the charging indicator on the instru- ment cluster is illuminated, stop the engine
of another vehicle, disconnect the cables in
the reverse order. For emergencies

14. Place the compressor (N) with its air pres-
sure gauge (O) on top.
Pull out the compressor’s power cord (P), in-
sert the plug on the cord into the accessory
socket (Q), and then turn the electric motor
switch to the “ACC” position.
Turn ON the compressor switch (R) and in-
flate the tyre to the specified pressure. CAUTION
l
The
supplied compressor is designed only
for inflation of passenger vehicle tyres.
l The compressor is designed to run on a ve-
hicle’s 12 V power supply. Do not connect
it to any other power source.
l The compressor is not waterproof. If you
use it in rain, make sure water does not
get on it. CAUTION
l
Any
sand or dust sucked into the compres-
sor could make the compressor break
down. Do not place the compressor direct-
ly on any sandy or dusty surface when us-
ing it.
l Do not disassemble or modify the com-
pressor. Also, do not subject the air pres-
sure gauge to shock. It could malfunction.
15. Check
and adjust the tyre pressure with refer- ence to the air pressure gauge on the compres-
sor. If you overinflate the tyre, release air by
loosening the hose’s end fitting. (Refer to
“Tyre inflation pressures” on page 8-15.)
If there is a gap between the tyre and wheel
because the tyre has moved inward from the
wheel rim, press the periphery of the tyre to-
wards the wheel to close the gap before run-
ning the compressor. (With no gaps, the tyre
pressure will rise.) CAUTION
l
Be
careful not to get your fingers trapped
between the tyre and wheel as the tyre in-
flates.
l The surface of the compressor will get
hot while the compressor is running. Do
not keep the compressor running continu-
ously for more than 10 minutes. After us-
ing the compressor, wait for the compres-
sor to cool before using it again. CAUTION
l
If
the compressor becomes sluggish or
hot while operating, it is overheating. Im-
mediately place the switch in the OFF po-
sition and let the compressor cool down
for at least 30 minutes.
NOTE l If

the tyre pressure does not rise to the speci-
fied level within 10 minutes, the tyre may be
so severely damaged that the tyre sealant can-
not be used to effect an emergency repair.
Please contact a MITSUBISHI MOTORS Au-
thorized Service Point or another specialist
in this event.
16. Turn OFF the compressor switch, then pull the power cord plug out of the socket.
NOTE l Simply putting sealant and air into the tyre us-
ing the tyre repair kit does not seal the punc-
ture hole. Air will leak through the puncture
hole until the emergency repair procedure is
completed (through step 19 of these instruc-
tions).
17. When you have inflated the tyre to the speci- fied pressure, stow the compressor, bottle,
and other items in the vehicle and promptly
start driving the vehicle so that the tyre seal-
ant can spread evenly in the tyre. Drive with
great care. Do not exceed a speed of 80 km/h
(50 mph). Observe local speed limits. For emergencies
