Your vehicle is equipped with power brakesfor more braking force with reduced brakepedal effort. Your brakes are designed to operate at full capacity, even if the power assist is lost.If the power assist is lost, the effort needed to press the brake pedal is greater. If you should lose the power assist for somereason, the brakes will still work. If the power brake unit or either of the two brake hydraulic systems stop working prop-
WA R N I N G Always pay special attention to pedestri- ans. Even if the acou
stic vehicle alerting
system (AVAS) sounds, pedestrians may not notice your vehicle.
NOTE
 If the indicator light blinks, turn the electric motor switch back to the “LOCK” positionand again turn the switch to the “ON” posi- tion. It is not a malfunction if the indicator lightgoes off. If the indica
tor light blinks again,
however, have the vehicl
e inspected at a cer-
tified i-MiEV dealer as soon as possible.
Service brake Brake pedal
WA R N I N G Do not leave any obje
cts near the brake
pedal or let a floor
mat slide under it;
doing so could prevent the full pedalstroke that would be necessary in an emergency. Make sure that the pedal can be operated freely at
all times. Make sure
the floor mat is securely held in place.CAUTION It is important not to drive the vehicle with your foot resting on the brake pedal when braking is not required.
This practice can
result in very high brake temperatures, pre- mature pad wear, and pos
sible damage to the
brakes.

erly, the rest of the brake system will still work, but the vehicle will not slow down asquickly. You will know this ha
s happened if you find
you need to depress the brake pedal downfurther, or harder when slowing down or stop- ping, or if the brake warning light comes on.
N00532500162
The disc brakes have an alarm that makes ametallic squeal when
the brake pads have
worn down enough to need service. If youhear this sound, have
the brake pads replaced
at a certified i-MiEV dealer.
N00567300063
The brake assist system is a device assisting drivers who cannot depress the brake pedalfirmly such as in em
ergency stop situations
and provides greater braking force. If the brake pedal is depressed suddenly, the brakes will be applied with more force thanusual.
N00517900325
The anti-lock braking
system helps prevent
the wheels from locking up when braking. This helps you keep control of your vehicleand its direction.
WA R N I N G Never turn off the electric motor switch while driving. Doing so will result in a loss of power assist for the brakes and steer-ing, increasing the effort required to steer and brake the vehicle.NOTE
 At times, you may hear
the brake electric
vacuum pump for the power brakes operat-ing when the ready i
ndicator illuminates or
the brake pedal is depressed. This sound is normal a
nd does not indicate a
problem.
Brake pad wear alarm
WA R N I N G Driving with worn brake pads will make it harder to stop, and can cause an accident.
Brake assist system
CAUTION The brake assist system is not a device designed to exercise
braking force greater
than its capacity. Make
sure to always keep a
sufficient distance be
tween vehicles in front
of you without relying too much on the brake assist system.NOTE
 Once the brake assist system is operational, it maintains great braking force even if the brake pedal is lightly released.To stop its operation, completely remove your foot from the brake pedal.
 The brake assist syst
em may become opera-
tional when the brake pedal is fullydepressed even if it
has not been depressed
suddenly.  When the brake assist system is in use while driving, you may feel as if the depressed brake pedal is soft, the pedal moves in small motions in conjuncti
on with the operation
noise, or the vehicle body and the steering wheel vibrate. This occurs when the brake assist system is ope
rating normally and does
not indicate faulty
operation. Continue to
depress the brake pedal.  You may hear an operation noise when the brake pedal is depre
ssed suddenly while sta-
tionary. This does not
indicate a malfunction
and the brake assist sy
stem is operating nor-
mally.
Anti-lock braking system

 When using the anti-lock brakes (sudden braking), steering is
slightly different
from normal driving conditions. Use the steering wheel carefully.  Always keep a safe distance from the vehicle in front of you. Even if your vehi- cle is equipped with
the anti-lock braking
system, leave a greater braking distance when: • Driving on gravel or snow-covered roads. • Driving on uneven road surfaces.  Operation of anti-lock braking system is not restricted to situations where brakes are applied suddenly. This system mayalso prevent the wheels from locking when you drive over manholes, steel roadwork plates, road markings, or anyuneven road surface.  When the anti-lock braking system is in use, you may feel the brake pedal vibrat-ing and hear a unique sound. You may also feel as if the pedal resists being pressed.In this situation, simply hold the brake pedal down firmly. Do not pump the brake, which will result in reducedbraking performance.
 An operation noise may be emitted from under the hood in the following situations.The sound is associated with checking the operations of the anti-lock braking sys- tem.At this time, you may feel a shock from the brake pedal if you depress it. These do not indicate a malfunction.• When the electric motor switch is set to the “ON” position. • When the vehicle is driven for a while after the electric motor is turned on.
 The ABS can be used after the vehicle has reached a speed over approximately 6 mph (10 km/h). It stops working when the vehicle slows below approximately 3 mph(5 km/h).
N00531600661
This light comes on in the event of a malfunc-tion in the anti-lock braking system. It willalso come on as a self-check for a few sec- onds when the electric motor switch is turned to the “ON” position.
Always make sure that
the light goes out befo
re beginning to drive.
Driving hints
CAUTIONThe anti-lock braking system cannot prevent accidents. It is your
responsibility to take
safety precautions and to drive carefully.  Be sure to use the spec
ified type and size of
tire on all four wheels. Otherwise, the ABS may not work properly. Do not install any aftermarket limited slip differential (LSD) on your vehicle. The ABSmay stop functioning properly.
Anti-lock braking system warn- ing light
CAUTION If the anti-lock braking system warning light comes on and stays on af
ter starting the elec-
tric motor unit or while driving, it means that the anti-lock braking system is not workingand that only the standard brake system is available. (The standard brake system will still work properly.) If this happens, takeyour vehicle to a certif
ied i-MiEV dealer as
soon as possible.

Avoid hard braking and high-speed driving. Stop the vehicle in a safe place, put the selec- tor lever to the “P” (PARK) position and turn off the electric motor unit. Restart the electric motor unit and check tosee whether the light goes out after a few minutes driving; if it then remains off during driving, there is no problem.However, if the warning light does not disap- pear, or if it comes on
again when the vehicle
is driven, we recommend you to have thevehicle checked. The ABS and brake force distribution func- tion 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 rec- ommend you to have th
e vehicle checked.
N00568400058
The power steering system operates while the electric motor unit is running. It helps reduce the effort needed to turn the steering wheel. The power steering system has mechanicalsteering capability in ca
se the power assist is
lost. If the power assist is lost for some rea- son, you will still be able to steer your vehi-cle, but you will notice it takes much more effort to steer. If this happens, have your vehi- cle inspected at a certified i-MiEV dealer.
If the warning light illuminates while driving If only the ABS warning light illu- minate If the ABS warning light and brake warning light illuminate at the same time
NOTE
 The warning light may
be illuminated when
the electric motor unit is started while the12V starter battery voltage
is low, but this is
not an ABS malfunction. When the main drive lithium-ion battery is charged, the 12V starte
r battery is charged at
the same time, and the
warning light will go
out. If the warning light does
not go out or illumi-
nates from time to time even after the battery is charged, take your ve
hicle to a certified i-
MiEV dealer and have
the system checked as
soon as possible.  After driving on snow or icy roads, remove any snow and ice whic
h may have been left
around the wheels. On ve
hicles that have an
anti-lock braking system, be careful not todamage the wheel spee
d sensors (A) or the
cables located at each wheel.Front

N00574400024
If there is a malfunction in the system, the warning light will come on.Under normal conditions
, the warning light
comes on when the electric motor switch is turned to the “ON” position and goes off afew seconds later.
N00559100163
The active stability c
ontrol (ASC) takes over-
all control of the anti-lock braking system, traction control function and skid controlfunction to help maintain the vehicle’s con- trol. Also refer to the following pages on the anti-lock braking system, traction controlfunction and skid control function. Anti-lock braking system (ABS)

WA R N I N GDo not turn the key from the ON position while the vehicle is moving. Stopping theelectric motor unit would make the steer-ing wheel extremely hard to turn, possibly resulting in an accident.NOTE
 During repeated full-lock turning of the steering wheel (for example, while you aremaneuvering the vehicle into a parking space), a protection
function may be acti-
vated to prevent overheating of the powersteering system. This f
unction will make the
steering wheel gradually harder to turn. In this event, limit your turning of the steeringwheel for a while. When the system has cooled down, the steering effort will return to normal.  If you turn the steering wheel while the vehi- cle is stationary with
the headlights on, the
headlights may become
dim. This behavior
is not abnormal. The headlights will return to their original brightne
ss after a short while.
Electric power steering system warning light
CAUTION If the warning light a
ppears while the elec-
tric motor unit is running, have the vehicle inspected at a certified i-MiEV dealer as soon as possible. It may become harder toturn the steering wheel.
Active stability control (ASC)
CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physics from acting on the vehicle. This system, like any other system, has li
mits and cannot help
you to maintain traction and control of the vehicle in all circumstances. Reckless driv- ing can lead to accident
s. It is the driver’s
responsibility to drive carefully. This means taking into account the tr
affic, road and envi-
ronmental conditions. Be sure to use the specified type and size of tire on all four wheels
. Otherwise, the ASC
may not work properly. Do not install any aftermarket limited slip differential (LSD) on
your vehicle. The ASC
may stop functioning properly.

On slippery surfaces, the traction control function prevents the drive wheels from spin- ning excessively, thus helping the vehicle to start moving from a stopped condition. It alsoprovides sufficient driving force and steering performance as the vehicle turns while press- ing the acceleration pedal.
N00546800049
The skid control function is designed to help the driver maintain control of the vehicle on slippery roads or during rapid steeringmaneuvers. It works by controlling the elec- tric motor unit output and the brake on each wheel.
N00559401277
The ASC is automatically activated when theelectric motor switch is turned to the “ON” position. You can deacti
vate the system by
pressing down the ASC OFF switch for 3 sec-onds or longer. When the ASC is deacti
vated, the indica-
tor will be illuminated. To reactivate the
ASC, momentarily
press the ASC OFF
switch; the indicator is turned off.
NOTE
 An operation noise may be emitted from under the hood in the fo
llowing situations.
The sound is associated
with checking the
operations of the ASC.
At this time, you may
feel a shock from the brake pedal if you depress it. These do not indicate a malfunc-tion. • When the electric motor switch is set to the “ON” position. • When the vehicle is driven for a while after the electric motor unit is turned on.
 When the ASC is acti
vated, you may feel a
vibration in the vehicle body or hear a whin- ing sound from under the hood. This indicates that the system is operatingnormally. It does not i
ndicate a malfunction.
 When the anti-lock braking system warning light is illuminated, the ASC is not active.
Traction control function
CAUTION When driving a vehicle on a snowy or icy road, be sure to install snow tires and drivethe vehicle at moderate speeds.
Skid control function
NOTE
 The skid control func
tion operates at speeds
of about 9 mph (15 km/h) or higher.
ASC OFF switch
CAUTION For safety reasons, the ASC OFF switch should be operated when your vehicle isstopped.  Be sure to keep the ASC on while driving in normal circumstances.NOTE
 Using the ASC OFF swit
ch turns off both the
skid control function a
nd the traction control
function.  When moving out of mud, sand or fresh snow, pressing the ac
celerator pedal may not
allow the electric motor speed to increase. Insuch situations, temporarily deactivate the ASC, using the ASC OFF switch.

N00546900053
The indicators should illuminate when the electric motor switch is turned to the “ON” position, and should turn
off after a few sec-
onds.If the indicator stays on
or does not illuminate
when the electric motor switch is turned to the “ON” position, have the vehicle inspectedby a certified i-MiEV de

ble. indicator blinks when the ASC is operat- ing. indicator is illuminated when the ASC is deactivated.
N00530201537
The tire pressure monitoring system uses tire inflation pressure sensors (A) on the wheels to monitor the tire inflation pressures. The
system only indicates wh
en a tire is signifi-
cantly under-inflated.
 If you continue to press the ASC OFF switch after the ASC is turned off, the “mistakenoperation protection f
unction” will activate
and the ASC will turn back on.
ASC indicator, ASC OFF indi- cator
CAUTION When indicator blinks, the ASC is oper- ating, which means that the road is slippery or that your vehicle’
s wheels are beginning
to slip. If this happens, drive slower.NOTE
CAUTION If an abnormal condition occurs in the sys- tem while driving, the and indicators will illuminate. In these cases, follow these procedures:• Park your vehicle in
a safe place and stop
the electric motor unit. Restart the electric motor unit again and check whether the and indicators go out
. If these indicators
go out, there is no abnormal condition. If the and indicators remain on even after your vehicle is driven a short distance after re-starting the electric motor unit, have the vehicle inspected by a certified i- MiEV dealer as soon as possible.
 When towing the vehicle with only the rear wheels raised off the ground, do not placethe electric motor switch in the “ON” posi- tion. Placing the electric motor switch in the “ON” position could ca
use the ASC to oper-
ate, resulting in an accident. For details, refer to
“Towing” on page 8-12.
Tire pressure monitoring system
NOTE
 The tire pressure monitoring system is not a substitute for regularly
checking tire infla-
tion pressures. Be sure to check the tire inflation pressures as described in “Tires” on page 9-10.

When the electric motor switch is turned to the “ON” position, this light normally illumi- nates and goes off a
few seconds later.
If one or more of the vehicle tires is signifi-cantly under-inflated, ho
wever, this light will
remain illuminated while the electric motor switch is in the “ON” position.Refer to “If the warning light illuminates while driving” on page 5-32 and take the nec- essary measures.
Each tire, including the spare (if provided), should be checked monthly when cold andinflated to the inflation pressure recom- mended by the vehicle manufacturer on the vehicle placard or tire in
flation pressure label.
(If your vehicle has tires of a different size than the size indicate
d on the vehicle placard
or tire inflation pressure label, you shoulddetermine the proper ti
re inflation pressure
for those tires.) As an added safety fe
ature, your vehicle has
been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of yourtires is significan
tly under-inflated.
Accordingly, when the low tire pressure tell- tale illuminates, you s
hould stop and check
your tires as soon as
possible, and inflate
them to the proper pressure.
 The tire inflation pressure sensor (A) is installed in the illustrated location. Replacegrommet (B) with a new one when the tire isreplaced. For details, please c
ontact a certified i-MiEV
dealer.
Tire pressure monitoring sys- tem warning light
NOTE
CAUTION If the tire pressure monitoring system warn- ing light does not illuminate when the elec-tric motor switch is turned to the “ON”position, it means that
the tire pressure moni-
toring system is not working properly. Have the system inspected by a certified i-MiEVdealer. In such situations, a malfunctioning of the system may be preventing the monitoring ofthe tire pressure. Avoid sudden braking, sharp turning and high-speed driving. If a malfunction is detected in the tire pres- sure monitoring system, the tire pressure monitoring system warn
ing light will blink
for approximately 1 minute and then remain continuously illuminated. The warning light will issue further warnings each time theelectric motor unit is re
started as long as the
malfunction exists. Check to see whether
the warning light goes
off after few minutes of driving. If it then goes off during driving, there is no problem.However, if the warning light does not go off, or if it blinks again when the electric motor unit is restarte
d, have the vehicle
inspected by a certified i-MiEV dealer. In such situations, a malfunctioning of the system may be preventing the monitoring ofthe tire pressure. For safety reasons, when the warning light appears while driving, avoid sudden braking, sharp turning andhigh-speed driving.
