2019 NISSAN LEAF park assist

• When the shif t lever is not in the D (Drive)or B mode
• When the parking brake is applied
• When the VDC operates (including the traction control system)
• When a wheel slips
When the system is not operating properly,
the chime sounds and the color of the
cruise indicator will change to orange.
Action to take
If the color of the cruise indicator changes
to orange, stop the vehicle in a safe place
and place the shif t lever in the P (Park) po-
sition. Turn the EV system off, restart the EV
system, resume driving, and then perform
the setting again.
If it is not possible to set or the indicator
stays on, it may indicate that the system
is malfunctioning. Although the vehicle
is still drivable under normal conditions,
have the vehicle checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.
WARNING
Failure to follow the warnings and in-
structions for proper use of the Pro-
PILOT Assist system could result in
serious injury or death.
• ProPILOT Assist is not a self-driving system. Within the limits of its capa-
bilities, as described in this manual,
it helps the driver with certain driv-
ing activities.
• The ProPILOT Assist system is not a replacement for proper driving pro-
cedures and is not designed to cor-
rect careless, inattentive or absent-
minded driving. ProPILOT Assist will
not always steer the vehicle to keep
it in the lane. The ProPILOT Assist
system is not designed to prevent
loss of control. It is the driver’s re-
sponsibility to stay alert, drive
safely, keep the vehicle in the travel-
ing lane, and be in control of the
vehicle at all times. • There are limitations to the ProPILOT
Assist system capability. The Pro-
PILOT Assist system does not func-
tion in all driving, traffic, weather,
and road conditions. It is the driver’s
responsibility to stay alert, drive
safely, keep the vehicle in the travel-
ing lane, and be in control of the
vehicle at all times.
• The ProPILOT Assist system is only an aid to assist the driver and is not a
collision warning or avoidance de-
vice.
• The ProPILOT Assist system is for highway use only and is not in-
tended for city driving. Failure to ap-
ply the brake or steer the vehicle
when necessary may result in a seri-
ous accident.
• Always observe posted speed limits and do not set the speed over them.
• Never take your hands off the steer- ing wheel when driving. Always keep
your hands on the steering wheel
and drive your vehicle safely.
• Never unfasten your safety belt when using ProPILOT Assist. Doing

Starting and driving5-145

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 is on, the power
assist for the steering will cease op-
eration. You will still have control of
the vehicle but the steering will be
harder to operate.
The 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 re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and help protect it from
getting damaged. When the power assis-
tance 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 repeating such steering
wheel operations 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 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.
POWER STEERING SYSTEM
BRAKE SYSTEM
5-146Starting and driving

The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the brake
pedal and apply the accelerator when the
vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is placed in the D (Drive), Bmode, or R (Reverse) position.
• The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds.
Af ter 2 seconds the vehicle will begin to roll
back and hill start assist will stop operating
completely.
Hill start assist will not operate when the
shif t lever is placed in the N (Neutral) or P
(Park) position or on a flat and level road.
CAUTION
To prevent damage to the Li-ion bat-
tery: Do not store the vehicle in tem-
peratures below -13°F (-25°C) for over
seven days. If the outside temperature
is -13°F (-25°C) or less, the Li-ion battery
may freeze and it cannot be charged or
provide power to run the vehicle. Move
the vehicle to a warm location.
NOTE:
• Connect the charger to the vehicle and
place the power switch in the OFF posi-
tion when parking the vehicle if tem-
peratures may go below -4°F (-20°C). For
models with 40 kWh battery model, this
provides external power to the Li-ion
battery warmer (if so equipped) when it
operates and does not discharge the Li-
ion battery. Vehicle driving range is re-
duced if the Li-ion battery warmer (if so
equipped) operates (Li-ion battery tem-
perature approximately -4°F (-20°C) or
colder) while driving the vehicle. You
may need to charge the Li-ion battery
sooner than in warmer temperatures. •
The Li-ion battery requires more time to
charge when the Li-ion battery warmer
(if so equipped) operates.
•
The predicted charging time displayed
on the meter and navigation system (if so
equipped) increases when the Li-ion bat-
tery warmer (if so equipped) operates.
• Vehicle range may be substantially re-
duced in extremely cold conditions (for
example under -4°F (-20°C)).
• Using the climate control system to
heat the cabin when outside tempera-
ture is below 32°F (0°C) uses more elec-
tricity and affects vehicle range more
than when using the heater when the
temperature is above 32°F (0°C).
• Climate control performance is reduced
when using the Climate Ctrl. Timer or
Remote Climate Control while the Li-ion
battery warmer (if so equipped) oper-
ates (for models with 40 kWh battery
model). Set only the charging timer [End
Time] when charging in cold weather.
The vehicle automatically determines
when to start charging to fully charge
the Li-ion battery, even if the Li-ion bat-
tery warmer operates. Charging ends
before the set end time if the Li-ion bat-
tery is fully charged.
