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 system may become operational when the
brake pedal is fully depressed 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 conjunction with the operation
noise, or the vehicle body and the steering wheel vibrate.
This occurs when the brake assist system is operating nor-
mally and does not indicate faulty operation. Continue to
depress the brake pedal.

You may hear an operation noise when the brake pedal is
depressed suddenly while stationary. This does not indi-
cate a malfunction and the brake assist system is operating
normally.
Anti-lock braking system
N00517900325
The anti-lock braking system helps prevent the wheels from
locking up when braking. This helps you keep control of your
vehicle and its direction. Driving hints
When using the anti-lock brakes (sudden braking), steer-
ing 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 vehicle 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
may also prevent the wheels from locking when you drive
over manholes, steel roadwork plates, road markings, or
any uneven road surface.

When the anti-lock braking system is in use, you may feel
the brake pedal vibrating 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
reduced braking 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 system.
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” posi-
tion.
• 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).
Anti-lock braking system warning light
N00531600661
This light comes on in the event of a malfunction in the anti-
lock braking system. It will also come on as a self-check for a
few seconds when the electric motor switch is turned to the
“ON” position. Always make sure that the light goes out before
beginning to drive.
CAUTION
!
The anti-lock braking system cannot prevent acci-
dents. It is your responsibility to take safety precau-
tions and to drive carefully.
Be sure to use the specified type and size of tire on
all four wheels. Otherwise, the ABS may not work
properly.
Do not install any aftermarket limited slip differen-
tial (LSD) on your vehicle. The ABS may stop func-
tioning properly.
CAUTION
!
If the anti-lock braking system warning light comes
on and stays on after starting the electric motor unit
or while driving, it means that the anti-lock braking
system is not working and that only the standard
brake system is available. (The standard brake sys-
tem will still work properly.) If this happens, take
your vehicle to a certified i-MiEV dealer as soon as
possible.

If the warning light illuminates while driving
N00531700590
If only the ABS warning light illuminateAvoid hard braking and high-speed driving. Stop the vehicle in
a safe place, put the selector lever to the “P” (PARK) position
and turn off the electric motor unit.
Restart the electric motor unit and check to see 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 disappear, or if it comes
on again when the vehicle is driven, we recommend you to
have the vehicle checked.If the ABS warning light and brake warning light illu-
minate at the same timeThe 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 the vehicle
checked.NOTE
The warning light may be illuminated when the electric
motor unit is started while the 12V starter battery voltage
is low, but this is not an ABS malfunction.
When the main drive lithium-ion battery is charged, the
12V starter battery is charged at the same time, and the
warning light will go out.
If the warning light does not go out or illuminates from
time to time even after the battery is charged, take your
vehicle 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 which may have been left around the wheels. On vehi-
cles that have an anti-lock braking system, be careful not
to damage the wheel speed sensors (A) or the cables
located at each wheel.

3Electric power steering system (EPS)
N00568400045
The electric power steering system (EPS) operates while the
electric motor unit is running.
The EPS uses an electric motor to assist the turning of the
steering wheel.
The EPS has mechanical steering capability in case the power
assist is lost. If the power assist is lost for some reason, you
will still be able to steer your vehicle. If the power assist is lost,
you will notice it takes much more effort to steer and that there
is much more “free play” in the steering wheel. If this happens,
take your vehicle to a certified i-MiEV dealer.NOTE
During repeated full-lock turning of the steering wheel
(for example, while you are maneuvering the vehicle into
a parking space), a protection function may be activated to
prevent overheating of the power steering system. 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 steer-
ing effort will return to normal.

!
Do not turn the key from the ON position while the
vehicle is moving. Stopping the electric motor unit
would make the steering wheel extremely hard to
turn, possibly resulting in an accident.

If you turn the steering wheel while the vehicle is station-
ary with the headlights on, the headlights may become
dim. This behavior is not abnormal. The headlights will
return to their original brightness after a short while.Electric power steering system warning light
N00574400011
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 a few seconds later.
If the warning light appears while driving
N00574500012
1. Stop the vehicle in a safe place, put the selector lever to
the “P” (PARK) position and turn off the electric motor
unit.
2. Restart the electric motor unit to check whether the warn-
ing light goes out; if it then remains off, there is no prob-
lem.
If the warning light does not go out, or it appears again
while driving, we recommend you to have your vehicle
inspected.
CAUTION
!
If the warning light appears during driving, it may
become harder to turn the steering wheel.

3-46 Features and controls
3Active stability control (ASC)
N00559100163
The active stability control (ASC) takes overall control of the
anti-lock braking system, traction control function and skid
control function to help maintain the vehicle’s control. Also
refer to the following pages on the anti-lock braking system,
traction control function and skid control function.
Anti-lock braking system (ABS) → P. 3 - 4 1
Traction control function → P. 3 - 4 6
Skid control function → P. 3 - 4 7
NOTE
An operation noise may be emitted from under the hood in
the following 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 malfunction.
• When the electric motor switch is set to the “ON” posi-
tion.
• When the vehicle is driven for a while after the electric
motor unit is turned on.

When the ASC is activated, you may feel a vibration in
the vehicle body or hear a whining sound from under the
hood.
This indicates that the system is operating normally. It
does not indicate a malfunction.

When the anti-lock braking system warning light is illu-
minated, the ASC is not active.Traction control function
N00559200050
On slippery surfaces, the traction control function prevents the
drive wheels from spinning excessively, thus helping the vehi-
cle to start moving from a stopped condition. It also provides
sufficient driving force and steering performance as the vehicle
turns while pressing the acceleration pedal.
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
limits and cannot help you to maintain traction and
control of the vehicle in all circumstances. Reckless
driving can lead to accidents. It is the driver’s
responsibility to drive carefully. This means taking
into account the traffic, road and environmental
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 differen-
tial (LSD) on your vehicle. The ASC may stop func-
tioning properly.
CAUTION
!
When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.

Skid control function
N00546800049
The skid control function is designed to help the driver main-
tain control of the vehicle on slippery roads or during rapid
steering maneuvers. It works by controlling the electric motor
unit output and the brake on each wheel.NOTE
The skid control function operates at speeds of about 9
mph (15 km/h) or higher.
ASC OFF switch
N00559400238
The ASC is automatically activated when the electric motor
switch is turned to the “ON” position. You can deactivate the
system by pressing down the ASC OFF switch for 3 seconds or
longer.
When the ASC is deactivated, the indicator will be illumi-
nated. To reactivate the ASC, momentarily press the ASC OFF
switch; the indicator is turned off.
CAUTION
!
For safety reasons, the ASC OFF switch should be
operated when your vehicle is stopped.
Be sure to keep the ASC on while driving in normal
circumstances.

NOTE
Using the ASC OFF switch turns off both the skid control
function and the traction control function.

When moving out of mud, sand or fresh snow, pressing
the accelerator pedal may not allow the electric motor
speed to increase. In such situations, temporarily deacti-
vate the ASC, using the ASC OFF switch.

If you continue to press the ASC OFF switch after the
ASC is turned off, the “mistaken operation protection
function” will activate and the ASC will turn back on.

The indicators should illuminate when the electric motor
switch is turned to the “ON” position, and should turn off after
a few seconds.
If the indicator stays on or does not illuminate when the elec-
tric motor switch is turned to the “ON” position, have the vehi-
cle inspected by a certified i-MiEV dealer as soon as possible.

CAUTION
!
When indicator blinks, the ASC is operating,
which means that the road is slippery or that your
vehicle’s wheels are beginning to slip. If this hap-
pens, drive slower.

3 Tire pressure monitoring system
N00530200426
The tire pressure monitoring system uses tire inflation pressure
sensors (A) on the wheels to monitor the tire inflation pres-
sures. The system only indicates when a tire is significantly
under-inflated.
CAUTION
!
If an abnormal condition occurs in the system while
driving, the and indicators will illuminate.
In these cases, follow these procedures:
• Park your vehicle in a safe place and stop the elec-
tric motor unit. Restart the electric motor unit
again and check whether the and indicators
go out. If these indicators go out, there is no abnor-
mal 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 place the electric motor
switch in the “ON” position. Placing the electric
motor switch in the “ON” position could cause the
ASC to operate, resulting in an accident.
For details, refer to “Towing” on page 6-19.
