WARNING
. If the READY to drive indicator light
is OFF while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
. When the electric power steering
warning light illuminates while the
READY to drive indicator light ON,
the power assist for the steering will
cease operation. You will still have
control of the vehicle but the steer-
ing will be harder to operate.
The electric power steering system is designed
to provide power assistance while driving to
operate the steering wheel with less effort.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent
overheating of the electric power steering
system and help protect it from getting da-
maged. While the power assistance is reduced,
steering wheel operation will become harder.
When the temperature of the electric power
steering system goes down, the power assis-
tance level will return to normal. Avoid repeating
such steering wheel operations that could cause
the electric power steering system to overheat.
You may hear a noise when the steering wheel is
operated quickly. However, this is not a mal-
function.
If the electric power steering warning light
illuminates while the READY to drive indicator
light is ON, it may indicate the electric power
steering system is not functioning properly and
may need servicing. Have the electric power
steering system checked by a NISSAN certified
LEAF dealer. (See “Electric power steering
warning light” in the “2. Instruments and
controls”.)
The power assist for steering stops operating
when both the electric power steering warning
light and READY to drive indicator light are
illuminated. You will still have control of the
vehicle. However, greater steering effort is
needed, especially in sharp turns and at low
speeds.
BRAKING PRECAUTIONS
This vehicle is equipped with two braking
systems:
1. Hydraulic brake system
2. Regenerative brake system
Hydraulic brake system
The hydraulic brake system is similar to the
brakes used on conventional vehicles.
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Regenerative brake system
The primary purpose of regenerative brake
system is to provide some power to help
recharge the Li-ion battery and extend driving
range. A secondary benefit is “engine braking”
that operates based on battery conditions.
In the D range, when the accelerator is released,
the regenerative brake system provides some
deceleration and generates power for the Li-ion
battery. Power is also generated when the brake
pedal is applied.
When you put the shift selector in the ECO
position and take your foot off the accelerator
pedal, more regenerative brake is applied than in
the D (Drive) position. However, during high-
Starting and driving 5-21
