2022 NISSAN LEAF traction control

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle traveling ahead. This may cause the
radar system to decelerate or accelerate
the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering ma-
neuver or traveling position in the lane, etc.)
or vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
System Temporarily Unavailable
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A
Under the following conditions, the ICC sys-
tem is automatically canceled. A chime will
sound and the system will not be able to be
set:
• Any door is open.
• The driver’s seat belt is not fastened.
• The vehicle ahead is not detected and
your vehicle is traveling below the speed
of 15 mph (24 km/h).
• Your vehicle has been stopped by the ICC system for approximately 3 minutes or
longer.
• The shif t lever is not in the D (Drive) posi- tion or B mode.
• The electronic parking brake is applied.
• The Vehicle Dynamic Control (VDC) sys- tem is turned off.
• The Automatic Emergency Braking with Pedestrian Detection applies harder
braking.
• VDC (including the traction control sys- tem) operates.
• A wheel slips.
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor.

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-DA
system could result in serious injury or
death.
• The I–DA system is only a warning to
inform the driver of a potential lack
of driver attention or drowsiness. It
will not steer the vehicle or prevent
loss of control.
• The I–DA system does not detect and
provide an alert of the driver’s lack
of attention or fatigue in every
situation.
• It’s the driver’s responsibility to:
– stay alert,
– drive safely,
– keep the vehicle in the traveling
lane,
– be in control of the vehicle at all
times,
– avoid driving when tired,
– avoid distractions (texting, etc.). The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.
I-DA SYSTEM OPERATION
If the system detects driver fatigue or that
driver attention is decreasing, the mes-
sage “Take a break?” appears in the vehicle
information display and a chime sounds
when the vehicle is driven at speeds above
37 mph (60 km/h).
The system continuously monitors driver
attention and can provide multiple warn-
ings per trip.
The system resets and starts reassessing
driving style and steering behavior when
the power switch is cycled from the ON to
the OFF position and back to the ON
position.

Self-test feature
The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric pumps,
hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature
that tests the system each time you place
the power switch in the READY to drive po-
sition and move the vehicle at a low speed
in forward or reverse. When the self-test
occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN certified LEAF dealer for this
service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds above 3 to 6 mph (5 to 10
km/h). The speed varies according to road
conditions.When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
drivers responsibility to stay alert, drive
safely and be in control of the vehicle at
all times. The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions.
• Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power
is transferred to a drive wheel on the
same axle that is not slipping.
• Controls brake pressure and traction motor output to reduce drive wheel slip
based on vehicle speed (traction control
function).
• Controls brake pressure at individual wheels and traction motor output to help
the driver maintain control of the vehicle
in the following conditions:– Understeer (vehicle tends to not follow the steered path despite increased
steering input).
– Oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver main-
tain control of the vehicle, but it cannot
prevent loss of vehicle control in all driving
situations.

5-164Starting and driving

•If traction motor control related
parts are not NISSAN recommended
or are extremely deteriorated, the
indicator light may illuminate.
• When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may illuminate. Do not drive on
these types of roads.
• When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may
illuminate. This is not a malfunction.
Restart the EV system af ter driving
onto a stable surface.
• If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light may illuminate.
• The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road. The chassis control is an electric control
module that includes the following
functions:
• Intelligent Trace Control
• Intelligent Ride Control

10-8Technical and consumer information

Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is typically used when towing
a vehicle behind a recreational vehicle,
such as a motor home.
CAUTION
• Failure to follow these guidelines can
result in severe reduction gear
damage.
• DO NOT tow this vehicle with all four
wheels on the ground (flat towing).
• For emergency towing procedures
see “Towing your vehicle” (P. 6-13).
NOTE:
If the Li-ion battery becomes completely
discharged:
• The vehicle is automatically placed in the ON position and it will not be pos-
sible to switch to the READY to drive
position.
• The vehicle is automatically switched to the N (Neutral) position and it will not
be possible to drive the vehicle.
For additional information, see “If the Li-
ion battery becomes completely dis-
charged” (P. 6-12). DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width.
For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use how-
ever, and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlledconditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include ac-
celeration, cornering, hydroplaning, or
peak traction characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to degen-
erate and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of per-
formance which all passenger car tires
must meet under the Federal Motor Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the labo-
ratory test wheel than the minimum re-
quired by law.
