2017 NISSAN LEAF check engine

• 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 the
regenerative brake system is to provide
some power to recharge the Li-ion battery
and extend driving range. A secondary ben-
efit 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 the battery’s useful life, use the fol-
lowing driving and charging habits where pos-
sible:
• Avoid exposing a vehicle to extreme ambient
temperatures for extended periods.
• Avoid storing a vehicle in temperatures below −13°F (−25°C) for more than 7 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 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 (if so
equipped)) . • 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 repetitive charging of the Li-ion battery with high battery state of charge.
• Moderate driving.
• Use of ECO mode.
• Do not operate the charging timer repeatedly while the charge connector is connected to the
vehicle after the Li-ion battery charging is com-
pleted. 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.

If any light does not come on or operate in a way
other than described, it may indicate a burned-
out bulb and/or a system malfunction. Have the
system checked. It is recommended that you visit
a NISSAN certified LEAF dealer for this service.
Some indicators and warnings are also displayed
on the vehicle information display. For additionalinformation, refer to “Vehicle information display”

WARNING LIGHTS
For additional information, refer to “Vehicle infor-
mation display” in this section.
12-volt battery charge
warning light
The DC/DC converter converts 400 volt Li-ion
battery voltage to charge the 12-volt battery.
This light illuminates continuously after the bulb is
checked when the power switch is in the ON
position, and turns off when the power switch is
placed in the READY to drive position.
When this warning light illuminates, a chime
sounds and the following warnings are also dis-
played.
• Master warning (red)
• EV system warning light The following messages also flash on and off on
the vehicle information display.
If the vehicle is being driven; “Stop the vehicle”
and if the vehicle is stopped; “When parked apply
parking brake”. When these messages flash, im-
mediately stop the vehicle in a safe location, pull
the parking brake switch and push the P (Park)
position switch on the shift lever to place the
vehicle in the P (Park) position. The warning on
the meter and the chime stops when the parking
brake is operated or the vehicle is in the P (Park)
position. Have the system checked. It is recom-
mended that you visit a NISSAN certified LEAF
dealer for this service.

that could cause the power steering system to
overheat.
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. It is
recommended that you visit a NISSAN certified
LEAF dealer for this service. For additional infor-
mation, refer to “Power steering warning light” in
the “Instruments and controls” section of this
manual.
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 the regenerative brake
system is to provide some power to help re-
charge the Li-ion battery and extend 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 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 B position and
take your foot off the accelerator pedal, more
regenerative brake is applied than in the D (Drive)
position. However, during high-speed driving you
may feel that regenerative brake provides less
deceleration than the engine braking in an ordi-
nary vehicle. This is normal.
Less deceleration is provided by the regenerative
brake system when the Li-ion battery is fully
charged. Regenerative brake is automatically re-
duced when the Li-ion battery is fully charged to
prevent the Li-ion battery from becoming over-
charged. Regenerative brake is also automati-
cally reduced when the battery temperature is
high/low (indicated by the red/blue zones on the
battery temperature gauge) to prevent Li-ion bat-
tery damage.
The brake pedal should be used to slow or stop
the vehicle depending on traffic or road condi-
tions. The vehicle brakes are not affected by
regenerative brake system operation.
NOTE:
•
When applying the regenerative brakes,
you may hear a sound coming from the
regenerative brake system. This is a nor-
mal operating characteristic of an EV.

smoothly and that the locks (if so equipped) hold
securely in all latched positions.
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 oper- ated in high temperatures or under severe condi-
tions require frequent checks of the 12–volt bat-
tery 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 elec-
tronic accessories 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 while. Water dripping from the air
conditioner after use is normal. If you should notice any leaks, check for 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, refer to
“Cleaning exterior” in the “Appearance and care”
section of this manual.
Windshield-washer fluid*: Check that there is
an adequate amount of fluid in the reservoir.
