check engine light NISSAN LEAF 2013 1.G Owners Manual

Release the accelerator pedal to slow downand do not apply the brakes when traffic and
road conditions allow. – This vehicle is equipped with a regenerative brake system. The primary purpose of re-
generative 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)
position, when the accelerator is released,
the regenerative brake system provides
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 vehicle range when the vehicle
was new. This is normal and expected, and does
not indicate 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 vehicle, store the
vehicle, how you charge the Li-ion battery and
Li-ion battery temperature during vehicle opera-
tion and charging. To maximize vehicle range, NISSAN recom-
mends using the default setting, long distance
mode (100% charge) . To maximize the battery’s
useful life, use the following driving and charging
habits where possible:
Avoid exposing a vehicle to extreme ambient
temperatures for extended periods.
Avoid storing a vehicle in temperatures below 13°F (25°C) for over 7 days.
Avoid leaving your vehicle for over 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 after use before charging.
Park/store your vehicle in cool locations out of direct sunlight and away from heat sources.
Avoid sustained high battery temperatures (caused, for example, by exposure to very high
ambient temperatures or extending highway
driving with multiple quick charges) .
Use the normal charging or trickle charging methods to charge the Li-ion battery and mini-
mize the use of public Fast Charge or Quick
Charger.
Avoid sustained high battery state of charge (caused, for example, by frequently charging to
100% state of charge and/or leaving the battery above 80% state of charge for long periods of
time) .
Allow the battery charge to be below at least 80% before charging.
Moderate driving.
Use of ECO mode.
If the vehicle will not be used for an extended period of time, charge the Li-ion battery using
the long life mode once every 3 months. Do not
operate the charging timer repeatedly while the
charge connector is connected to the vehicle
after 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. See Li-ion battery available charge
gauge in theInstruments and controls for
details.
LI-ION BATTERY MAINTENANCE
In addition to the regular maintenance recom-
mended by NISSAN, the LEAF requires some
special Li-ion battery inspections.

sible voiding of your warranty resulting from
EV-24EV Overview

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 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 steering will be harder to operate.
The power steering system is designed to pro-
vide 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 over-
heating of the power steering system and help
protect it from getting damaged. While the power
assistance is reduced, steering wheel operation
will become harder. When the temperature of the
power steering system goes down, the power
assistance level will return to normal. Avoid re-
peating such steering wheel operations that
could cause the power steering system to over-
heat. You may hear a noise when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the power steering warning light
illumi-
nates while the READY to drive indicator light is
ON, it may indicate the power steering system is
not functioning properly and may need servicing.
Have the power steering system checked by a
NISSAN certified LEAF dealer. (See Power
steering warning light in theInstruments and
controls section.)
The power assist for steering stops operating
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 sys-
tems:
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 sys-
tem is to provide some power to help recharge
the Li-ion battery and extend driving range. A
secondary benefit is “engine braking” that oper-
ates based on battery conditions.
In the D (Drive) 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 lever in the ECO position
and take your foot off the accelerator pedal, more

Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating properly.
Windshield defroster: Check that the air emits
from the defroster outlets properly and in suffi-
cient quantity when operating the heater or air
conditioner.
Windshield wiper and washer*: Check that
the wipers and washers operate properly and
that the wipers do not streak.
Under hood and vehicle
The maintenance items listed here should be
checked periodically.
12-volt battery (for serviceable battery)*:
Check the fluid level in each cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under severe conditions require frequent checks of the
12-volt battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery power when
the engine is not running (Phone chargers,
GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Coolant level*: Check the coolant level when
the motor compartment is cold.
Fluid leaks: Check under the vehicle for water
or other fluid leaks after the vehicle has been
parked for a short period of time. Water dripping
from the air conditioner after use is normal. If you
notice any leaks, check for the cause and have it
corrected immediately. Radiator and hoses:
Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure that
the hoses have no cracks, deformation, rot or
loose connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan and frame. At
the end of winter, the underbody should be thor-
oughly flushed with plain water, being careful to
clean those areas where mud and dirt may accu-
mulate. For additional information, see Cleaning
exterior in theAppearance and care section.
Windshield washer fluid*: Check that there is
an adequate amount of fluid in the reservoir.
