3-42 Features and controls

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.

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
NOTEAn 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.
