Parking brake break-in
Break in the parking brake shoes whenever the
holding effect of the parking brake is weakened
or whenever the parking brake shoes are re-
placed, in order to maintain optimum braking
performance.
This procedure is described in the vehicle Ser-
vice Manual, and it can be performed by a
NISSAN certified LEAF dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
The Anti-lock Braking System (ABS) is a sophisticated device, but it cannot
prevent accidents resulting from care-
less or dangerous driving techniques.
It can help maintain vehicle control
during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than
on normal surfaces even with ABS.
Stopping distances may also be longer
on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from the vehicle in front of you. Ultimately,
the driver is responsible for safety.
Tire type and condition may also affect braking effectiveness.
– When replacing tires, install thespecified size of tires on all four
wheels.
– For detailed information, see
Wheels and tires in theMainte-
nance and do-it-yourself section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you push the power
switch in the READY to drive position 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
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 vehicle
checked by a NISSAN certified LEAF dealer.
Starting and driving5-21

Normal operation
The ABS operates 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 ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation 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 operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle 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 out- put 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 in-
put)
– oversteer (vehicle tends to spin due to cer- tain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
warning in the instrument panel flashes. When
the warning flashes, note the following items. The road may be slippery or the system may
determine some action is required to help keep
the vehicle on the steered path.
You may feel a pulsation in the brake pedal and hear a noise or vibration from under the hood.
This is normal and indicates that the VDC sys-
tem is working properly.
Adjust your speed and driving according to the road conditions.
See VDC warning light in theInstruments and
controls section and VDC OFF indicator light
in the Instruments and controls section.
If a malfunction occurs in the system, the
warning illuminates in the lower display. The VDC
system automatically turns off when this warning
light is lit.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates
to indicate that the VDC system is off. When the
VDC switch is used to turn off the system, the
VDC system still operates to prevent one drive
wheel from slipping by transferring power to a
drive wheel that is not slipping. The
warn-
ing flashes if this occurs. All other VDC functions
are off and the
warning will not flash. The
VDC System is automatically reset to ON when

WARNING
Never rely solely on the hill start assist system to prevent the vehicle from
moving backward on a hill. Always
drive carefully and attentively. Depress
the brake pedal when the vehicle is
stopped on a steep hill. Be especially
careful when stopped on a hill on fro-
zen or muddy roads. Failure to prevent
the vehicle from rolling backwards
may result in a loss of control of the
vehicle and possible serious injury or
death.
The hill start assist system is not de- signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a steep
hill. Failure to do so may cause the
vehicle to roll backwards and may re-
sult in a collision or serious personal
injury.
The hill start assist may not prevent the vehicle from rolling backwards on a
hill under all load or road conditions.
Always be prepared to depress the
brake pedal to prevent the vehicle
from rolling backwards. Failure to do
so may result in a collision or serious
personal injury. 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 shift lever is shifted into D (Drive) , ECO, or
R (Reverse) position.
The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds. After 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 shift
lever is shifted into D (Drive) , ECO, or R (Re-
verse) position or on a flat and level road.CAUTION
To prevent damage to the Li-ion battery:
Do not store a vehicle in temperatures
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 tempera-
tures may go below -4°F (-20°C) . This pro-
vides external power to the Li-ion battery
warmer when it operates and does not
discharge the Li-ion battery. Vehicle driv-
ing range is reduced if the Li-ion battery
warmer operates (Li-ion battery tempera-
ture 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
operates.

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*:Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights and other lights are all
operating properly and installed securely. Also
check the aim of the headlights.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure that no wheel nuts are miss-
ing, and check for any loose wheel nuts. Tighten
if necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km) .
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires to the pres-
sure specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance: If the vehicle
pulls to either side while driving on a straight and
level road, or if you detect uneven or abnormal tire
wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty In-
formation Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming scheduled maintenance, cleaning the ve-
hicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure that the pedal does not
catch or require uneven effort. Keep the floor mat
away from the pedal.
Brake pedal: Check the pedal for smooth op-
eration and make sure that it has the proper distance under it when depressed fully. Check
the brake booster function. If the brake pedal
suddenly goes down further than normal, the
pedal feels spongy or the vehicle seems to take
longer to stop, contact a NISSAN certified LEAF
dealer immediately. Keep the floor mat away from
the pedal.
Brakes:
Check that the brakes do not pull the
vehicle to one side when applied.
Electric shift P (Park) position mechanis-
m:On a steep hill, check that the vehicle is held
securely while the vehicle is in the P (Park) posi-
tion without applying the brakes.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a steep hill with only the parking brake applied.
If the parking brake cannot keep a vehicle posi-
tion contact a NISSAN certified LEAF dealer.
Seat: Check seat position controls such as the
seat adjusters, seatback recliners, etc. to ensure
that they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints/headrests move up and down
smoothly and that the locks (if so equipped) hold
securely in all latched positions.
Maintenance and do-it yourself8-3

Contact a NISSAN certified LEAF dealer if
checking or replacement is required.If the brakes do not operate properly, have the
brakes checked by a NISSAN certified LEAF
dealer.
WARNING
Do not adjust the height of the brake
pedal. Doing so could alter the effective-
ness of the brakes, which could result in
a serious accident and personal injury. If
adjustment is required, contact a
NISSAN certified LEAF dealer.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warnings.
When a brake pad requires replacement, it will
make a high pitched scraping sound when the
vehicle is in motion. This scraping sound will first
occur only when the brake pedal is depressed.
After more wear of the brake pad, the sound will
always be heard even if the brake pedal is not
depressed. Have the brakes checked as soon as
possible if the wear warning sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.
Proper brake inspection intervals should
be followed. For additional information, see the
maintenance log section of your NISSAN Service
and Maintenance Guide.
