• 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
so automatically cancels the Pro-
PILOT Assist system.

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
To shut off the EV system in an emergency
situation while driving, perform the follow-
ing procedure.
• Rapidly push the power switch three con-secutive times in less than 1.5 seconds, or
• Push and hold the power switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires. When the low
tire pressure warning light is lit, and the “Tire
Pressure Low — Add Air” warning appears
on the vehicle information display, one or
more of your tires is significantly under-
inflated. If the vehicle is being driven with
low tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light. This system will activate only
when the vehicle is driven at speeds above
16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights
and audible reminders” in the “Instruments
and controls” section and “Tire Pressure
Monitoring System (TPMS)” in the “Starting
and driving” section of this manual.
WARNING
• Radio waves could adversely affect electric medical equipment. Those
who use a pacemaker should con-
tact the electric medical equipment
manufacturer for the possible influ-
ences before use. • If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with underinflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
af ter adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat
tire, repair it as soon as possible. If
no tire is flat and all tires are properly
inflated, have the vehicle checked. It
is recommended that you visit a cer-
tified LEAF dealer for this service.
EMERGENCY EV (ELECTRIC VEHICLE)
SHUT OFF FLAT TIRE
In case of emergency6-3
•The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
•Tires degrade with age and
use. Have tires, over 6 years old
checked by a qualified techni-
cian, because some tire dam-
age may not be obvious. Re-
place the tires as necessary to
prevent tire failure and pos-
sible personal injury.
•For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. For ad-
ditional information, refer to “Specifica-
tions” in the “Technical and consumerinformation” section of this manual for rec-
ommended types and sizes of tires and
wheels.
WARNING
• The use of tires other than those rec- ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, Vehicle Dy-
namic Control (VDC) system, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects
may lead to accidents and could re-
sult in serious personal injury.
• If your vehicle was originally equipped with four tires that were
the same size and you are only re-
placing two of the four tires, install
the new tires on the rear axle. Plac-
ing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an ac-
cident and personal injury. • If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or
interference with the brake discs.
Such interference can lead to de-
creased braking efficiency and/or
early brake pad/shoe wear. For ad-
ditional information on wheel-off
set dimensions, refer to “Wheels and
tires” in the “Technical and con-
sumer information” section of this
manual.
• When replacing a wheel without the TPMS such as the spare tire, the
TPMS will not function when a wheel
is replaced, the TPMS will not func-
tion and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on af-
ter 1 minute. It is recommended that
you visit a NISSAN certified LEAF
dealer for this service.
• Replacing tires with those not origi- nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
