Regenerative braking
N01205600013
It is equivalent to engine braking of a gasoline or diesel pow-
ered vehicle. When you take your foot off the accelerator pedal
during driving, motion energy is converted into electric energy
using the motor as a power generator.
During this conversion, braking force is generated and con-
verted electric energy is used to charge the main drive lithium-
ion battery. The generative braking force can be adjusted using
the selector lever.
Set the selector lever to “B” (REGENERATIVE BRAKE
MODE) or “ECO” (ECO MODE) position for increased regen-
erative braking as follows:

“B”: Strong regenerative braking (For downhill driving)

“ECO”: Moderate regenerative braking (For economical
driving or gentle downhill driving)NOTE
If a problem occurs in the electric motor unit, or if the
ABS and/or the ASC have been activated, the regenera-
tive braking will be restricted. The service brakes will still
operate.

Keep the brake pedal depressed until you are ready
to drive. When the vehicle is in the “D” (DRIVE),
“ECO” (ECO MODE), “B” (REGENERATIVE
BRAKE MODE) or “R” (REVERSE) position, if
you release the brake pedal and even if you do not
depress accelerator, the vehicle will creep and may
move slowly.

3 Parking brake
N00511400386
To park the vehicle, first bring it to a complete stop, fully
engage the parking brake, and set the selector lever to “P”
(PARK) position.To apply To release
When parking on a hill, apply the parking brake and turn the
front wheels toward the curb on a downhill grade, away from
the curb on an uphill grade.
1- Pull the lever up without pushing the button at the end of
hand grip.
When the parking brake is set and the electric motor switch
is in the “ON” position, the brake warning light in the instru-
ment cluster will come on.
Before driving, be sure to release the parking brake.
1- Pull the lever up slightly.
2- Press and hold the button at the end of the hand grip.
3- Push the lever downward.
CAUTION
!
Before driving, be sure that the parking brake is
fully released and brake warning light is off.
If a vehicle is driven without releasing the parking
brake, the brakes will be overheated, resulting in
ineffective braking and possible brake failure.

“N” NEUTRALUse this position only when the vehicle is stationary for an
extended length of time while driving, such as in a traffic jam.“D” DRIVEUse this position for normal driving.
“ECO” ECO MODEUse this position when you desire to limit power consumption
and/or when moderate regenerative braking is required.“B” REGENERATIVE BRAKE MODEUse this position when strong regenerative braking is required,
such as on a steep downhill.NOTE
When the main drive lithium-ion battery level is full or
nearly full, or the main drive lithium-ion battery tempera-
ture is low, the regenerative braking force may be reduced
and stronger effort may be required to operate the brakes.
WA R N I N G
!
Never move the selector lever to the “N” (NEU-
TRAL) position while the vehicle is in motion. You
will lose regenerative braking. In addition, a serious
accident could occur if the selector lever were inad-
vertently moved into the “P” (PARK) position or
“R” (REVERSE) position.
CAUTION
!
To avoid transmission damage, never shift into the
“D” (DRIVE) position from the “R” (REVERSE)
position while the vehicle is in motion.
WA R N I N G
!
While driving on a slippery road, do not use the “B”
position. Abruptly releasing the accelerator pedal
can apply strong regenerative braking causing the
vehicle to skid which could result in an accident.

Waiting
N00515000087
For short waiting periods, such as at traffic signals the vehicle
can be left in selector lever position and held stationary with
the service brake.
For longer waiting periods with the electric motor unit running,
place the selector lever in the “N” (NEUTRAL) position and
apply the parking brake, while holding the vehicle stationary
with the service brake.
Parking
N00515100075
To park the vehicle, first bring it to a complete stop, fully
engage the parking brake, and then move the selector lever to
the “P” (PARK) position.
If you are going to leave the vehicle unattended, always switch
off the electric motor unit and carry the key.NOTE
On a slope, be sure to apply the parking brake before
moving the selector lever to the “P” (PARK) position. If
you move the selector lever to the “P” (PARK) position
before applying the parking brake, it may be difficult to
disengage the selector lever from the “P” (PARK) position
when next you drive the vehicle, requiring application of a
strong force to the selector lever to move from the “P”
(PARK) position.
CAUTION
!
Before selecting a position with the electric motor
unit running and the vehicle stationary, fully
depress the brake pedal to prevent the vehicle from
creeping.
The vehicle will begin to move as soon as the trans-
mission is engaged, the brakes should only be
released when you are ready to drive away.
Depress the brake pedal with the right foot at all
times.
Using the left foot could cause driver movement
delay in case of an emergency.
Operating the accelerator pedal while the other foot
is resting on the brake pedal will affect braking effi-
ciency and may cause premature wear of brake
pads.
CAUTION
!
Never hold the vehicle stationary on a hill with the
accelerator. Always apply the parking brake and/or
service brake.

3 Service brake
N00517500305
Brake pedalOveruse of the brake can cause poor brake response and pre-
mature wear of the brake pads.
Power brakes
N00517600410
Your vehicle is equipped with power brakes for more braking
force with reduced brake pedal 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 some reason, the brakes
will still work.
If the power brake unit or either of the two brake hydraulic sys-
tems stop working properly, the rest of the brake system will
still work, but the vehicle will not slow down as quickly.
You will know this has happened if you find you need to
depress the brake pedal down further, or harder when slowing
down or stopping, or if the brake warning light comes on.
WA R N I N G
!
Do not leave any objects near the brake pedal or let
a floor mat slide under it; doing so could prevent the
full pedal stroke that would be necessary in an emer-
gency. 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, premature pad wear, and possible
damage to the brakes.
WA R N I N G
!
Never turn off the electric motor switch while driv-
ing. Doing so will result in a loss of power assist for
the brakes and steering, increasing the effort
required to steer and brake the vehicle.

Brake pad wear alarm
N00532500162
The disc brakes have an alarm that makes a metallic squeal
when the brake pads have worn down enough to need service.
If you hear this sound, have the brake pads replaced at a certi-
fied i-MiEV dealer.
Brake assist system
N00567300063
The brake assist system is a device assisting drivers who can-
not depress the brake pedal firmly such as in emergency stop
situations and provides greater braking force.
If the brake pedal is depressed suddenly, the brakes will be
applied with more force than usual.
WA R N I N G
!
Driving with worn brake pads will make it harder to
stop, and can cause an accident.
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
between 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 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.
