• Using the climate control system to heatthe cabin when the outside temperature
is below 32°F (0°C) uses more electricity
and affects vehicle range more than
when using the heater when the tem-
perature is above 32°F (0°C).
• When it is cold, use the steering wheel heater in substitution for the heater/air
conditioner. The steering wheel heater
consumes less power than the heater/
air conditioner.
• Release the accelerator pedal to slow down and do not apply the brakes when
traffic and road conditions allow.– – This vehicle is equipped with a regen-
erative brake system. The primary pur-
pose of the regenerative brake system
is to provide some power to recharge
the Li-ion battery and extend driving
range. A secondary benefit is “engine
braking” that operates based on Li-ion
battery conditions. In the D (Drive) posi-
tion, when the accelerator is released,
the regenerative brake system pro-
vides some deceleration and some
power to the Li-ion battery.LI-ION BATTERY LIFE
The Li-ion battery's ability to hold a charge,
like all batteries, decreases with battery
age and usage which results in decreased
vehicle range when compared to the ve-
hicle range when the vehicle was new. This
is normal and expected, and does not indi-
cate a malfunction of the vehicle or Li-ion
battery.
The Li-ion battery's ability to hold a charge
can be affected by how you drive the ve-
hicle, store the vehicle, how you charge the
Li-ion battery and Li-ion battery tempera-
ture during vehicle operation and charging.
To maximize the battery's useful life, use
the following driving and charging habits
where possible:
• Avoid exposing a vehicle to extreme am- bient temperatures for extended periods.
• Avoid storing a vehicle in temperatures below −13°F (−25°C) for more than seven
days.
• Avoid leaving your vehicle for more than 14 days where the Li-ion battery available
charge gauge reaches a zero or near zero
(state of charge).
• Allow the vehicle and Li-ion battery to cool down af ter use before charging. • Park/store your vehicle in cool locations
out of direct sunlight and away from heat
sources.
• Avoid sustained high battery tempera- tures (caused, for example, by exposure
to very high ambient temperatures or ex-
tending highway driving with multiple
quick charges [if so equipped]) .
• Use the normal charging or trickle charg- ing methods to charge the Li-ion battery
and minimize the use of public Fast
Charge or Quick Charger.
• Moderate driving.
• Use of ECO mode.
• Do not operate the charging timer re- peatedly while the charge connector is
connected to the vehicle af ter the Li-ion
battery charging is completed. Doing so
may discharge the 12-volt battery.
• The power of the Li-ion battery can be checked on the Li-ion battery available
charge gauge. For additional information,
refer to “Li-ion battery available charge
gauge” in the “Instruments and controls”
section of this manual.
EV OverviewEV-23
You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light
illuminates while the READY to drive indica-
tor light is on, it may indicate the power
steering system is not functioning properly
and may need servicing. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service. For additional
information, refer to “Power steering warn-
ing light” in the “Instruments and controls”
section of this manual.
The power assist for steering stops operat-
ing when both the 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.
BRAKE 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 hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Regenerative brake system
The primary purpose of the regenerative
brake system is to provide some power to
help recharge the Li-ion battery and ex-
tend driving range. A secondary benefit is
“engine braking” that operates based on
battery conditions.
In the D (Drive) range, when the accelerator
is released, the regenerative brake system
provides some deceleration and gener-
ates power for the Li-ion battery. Power is
also generated when the brake pedal is
applied.When you put the shif t lever in the B mode
and take your foot off the accelerator
pedal, more regenerative brake is applied
than in the D (Drive) position. However, dur-
ing high-speed driving you may feel that
regenerative brake provides less decelera-
tion than the engine braking in an ordinary
vehicle. This is normal.
Less deceleration is provided by the regen-
erative brake system when the Li-ion bat-
tery is fully charged. Regenerative brake is
automatically reduced when the Li-ion
battery is fully charged to prevent the Li-ion
battery from becoming overcharged. Re-
generative brake is also automatically re-
duced when the battery temperature is
high/low (indicated by the red/blue zones
on the battery temperature gauge) to pre-
vent Li-ion battery damage.
The brake pedal should be used to slow or
stop the vehicle depending on traffic or
road conditions. The vehicle brakes are not
affected by regenerative brake system op-
eration.
