cooling NISSAN LEAF 2019 Owner´s Manual

RANGE
The distance you can drive the vehicle
(range) varies considerably depending
upon available charge, weather, tempera-
ture, usage, battery age, topography, and
driving style.
Refer to the Monroney label (window sticker)
for the official EPA range. Your actual range
will vary and could be significantly less, either
initially or as the battery ages and with use
over time. For additional information, refer to
“Improve driving range” in this section for in-
formation on the factors that affect vehicle
range and how to use the vehicle to maxi-
mize vehicle range.
IMPROVE DRIVING RANGE
Vehicle range depends on a number of fac-
tors.
Actual vehicle range will vary depending
upon:
• Speed,
• Vehicle load,
• Electrical load from vehicle accessories,
• Traffic and road conditions,• Distance driven without stopping,
• Usage,
• Driving style,
• Battery age,
• Weather or temperature,
• Topography,
• Charging habits.
• Speed,
• Vehicle load,
• Electrical load from vehicle accessories,
• Traffic and road conditions.
NISSAN recommends the following driv-
ing habits to help maximize vehicle range:
Before driving:
• Follow recommended periodic main-
tenance.
• Keep tires inflated to correct pressure.
• Keep wheels in correct alignment.
• Pre-heat or pre-cool the interior cabin while the vehicle is charging.
• Remove unnecessary cargo from the vehicle. While driving:
• Drive in ECO mode
– The ECO mode helps reduce powerconsumption by reducing acceleration
when compared to the same accelera-
tor pedal position in the D (Drive) posi-
tion (normal mode).
• Drive at a constant speed. Maintain cruis- ing speeds with constant accelerator po-
sitions or by using cruise control when
appropriate.
• Accelerate slowly and smoothly. Gently press and release the accelerator pedal
for acceleration and deceleration.
• Drive at moderate speeds on the highway.
• Avoid extending highway driving with multiple quick charges.
• Avoid frequent stopping and braking. Maintain a safe distance behind other
vehicles.
• Turn off the air conditioner/heater when it is not necessary.
• Select a moderate temperature setting for heating or cooling to help reduce
power consumption.

WARNING
• If you use any medical electric de- vices, such as an implantable car-
diac pacemaker or an implantable
cardiovascular defibrillator, check
with the electric medical device
manufacturer concerning the ef-
fects that charging may have on im-
planted devices before starting the
charge operation. Charging may af-
fect the operation.
• Make sure there is no water or for- eign materials in the charge port,
charge connector, or electrical plug,
and that they are not damaged or
affected by rust or corrosion. If any
of these conditions are noticeable,
do not charge the Li-ion battery. This
may result in a short circuit or elec-
tric shock and could cause a fire
which may result in serious personal
injury or death.
• To avoid serious personal injury or death when the Li-ion battery is
charging, be aware of the following
precautions. – Do not touch the metal contacts
of the charge port, charge con-
nector, electrical plug or Genuine
NISSAN Adapter.
– Do not touch the vehicle and EVSE when there is lightning.
– Do not pull, twist, bend, step on, or drag the cable.
• Make sure the charge connector is removed from the charge port be-
fore starting your vehicle. If the
charge connector is only partially
engaged and the connector latch is
unlocked, it is possible to place the
EV in the READY to drive position.
• Do not touch the plug or the Genuine NISSAN Adapter if they are wet or
with wet hands. Do not put the plug
or the Genuine NISSAN Adapter in
water, liquid or snow. This may cause
an electric shock which may result in
serious personal injury or death.
• Do not disassemble or modif y the charge port, the EVSE or the Genuine
NISSAN Adapter. This may cause a
fire or an electric shock which may
result in serious personal injury or
death. • If you notice an unusual odor, smoke
or abnormal noises coming from the
vehicle, stop charging immediately.
• Be careful not to allow your hands, hair, jewelry or clothing to come into
contact with, or get caught in, the
traction motor cooling fan. The cool-
ing fan can start at any time during
charging.
• Do not use extension cords or adapters unless they are Genuine
NISSAN parts.
• Do not use the Genuine NISSAN Adapter with any devices except the
Genuine NISSAN EVSE.
• Do not allow an unattended child to handle or use this product.
•

mended that you visit a NISSAN certified
LEAF dealer for this service.
Electric shif t control
system warning light
This light illuminates to warn when a mal-
function occurs in the electric shif t control
system. When the master warning light illu-
minates, the chime sounds and the mes-
sage, “When parked apply parking brake”, is
displayed on the vehicle information dis-
play.
When the power switch is in the OFF posi-
tion, the chime sounds continuously. Make
sure the parking brake is applied.Have the system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.

gency shut-off system” in the “EV over-
view” section of this manual.
Low tire pressure warning
light
Your vehicle is equipped with a Tire Pres-
sure Monitoring System (TPMS) that moni-
tors the tire pressure of all tires. The low tire pressure warning light warns
of low tire pressure or indicates that the
TPMS is not functioning properly.
Af ter the power switch is placed in the ON
position, this light illuminates for about
1 second and then turns off.
Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
The “Low Tire Pressure — Add Air” warning
also appears on the vehicle information
display.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure to the recommended COLD
tire pressure shown on the Tire and Load-
ing Information label. The low tire pressure
warning light does not automatically turn
off when the tire pressure is adjusted. Af ter
the tire is inflated to the recommended
pressure, the vehicle must be driven at
speeds above 16 mph (25 km/h) to activate
the TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge to
check the tire pressure.
Instruments and controls2-21

WARNING
• The air conditioning cooling func- tion operates only when the power
switch is in the ON position or when
the READY to drive indicator light is
ON.
• Do not leave children or adults who would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadver-
tent operation of the vehicle. Also,
on hot, sunny days, temperatures in
a closed vehicle could quickly be-
come high enough to causes severe
or possibly fatal injuries to people or
animals. • Do not use the recirculation mode
for long periods as it may cause the
interior air to become stale and the
windows to fog up.
NOTE:
•Odors from inside and outside the ve-
hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
• When parking, set the heater or air con-
ditioner controls to turn off air recircu-
lation to allow fresh air into the passen-
ger compartment. This should help
reduce odors inside the vehicle. The climate control system (air conditioner
and heater functions) can be operated
when the READY to drive indicator light is
illuminated. However, while charging, the
climate control system can be used when
the power switch is in the ON position.

• Drive at a constant speed. Maintain cruis-ing speeds with a constant accelerator
position or by using cruise control when
appropriate.
• Accelerate slowly and smoothly. Gently press and release the accelerator pedal
for acceleration and deceleration.
• Drive at moderate speeds on the highway.
• Avoid frequent stopping and braking. Maintain a safe distance behind other
vehicles.
• Turn off the air conditioner/heater when it is not necessary.
• Select a moderate temperature setting for heating or cooling to help reduce
power consumption.
• Use the air conditioner/heater and close windows to reduce drag when cruising at
a highway speed. • 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 pedal is re-
leased, the regenerative brake system
provides some deceleration and some
power to the Li-ion battery. The ECO Drive Report appears for approxi-
mately 30 seconds af ter placing the power
switch in the OFF position, driving the ve-
hicle for more than 0.3 miles (500 m), and
pressing the
button on the steering
wheel.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting
it into the key hole or use the remote key-
less entry key fob.
ANTIFREEZE
In the winter when it is possible that the
outside temperature will drop below 32°F
(0°C), check the antifreeze to ensure proper
winter protection. For additional informa-
tion, refer to “Cooling system” in the “Main-
tenance and do-it-yourself ” section of this
manual.
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, refer to “12-volt battery” in the
“Maintenance and do-it-yourself ” section
of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system. Refill
before operating the vehicle. For additional
information, refer to “Cooling system” in the
“Maintenance and do-it-yourself ” section
of this manual.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads, NISSAN
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for the tire type, size,
speed rating and availability information.
For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires.Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded
snow tires.
Tire chains may be used. For additional in-
formation, refer to “Tire chains” in the “Main-
tenance and do-it-yourself ” section of this
manual.SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-
move ice and snow from the windows and
wiper blades.
• A shovel to dig the vehicle out of snow-drif ts.
• Extra windshield-washer fluid to refill the reservoir tank.
