2015 NISSAN LEAF brakes

•If the power switch position is in a posi-
tion other than ON or READY to drive, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle, and the stopping dis-
tance will be longer.
• When depressing the brake pedal, the
braking pedal feel will not be smooth or
may change when the cooperative regen-
erative brake system activates. However,
the electronically controlled brake system
is operating normally and this does not
indicate a malfunction.
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the brakes,
wearing out the brake pads and shoes faster and
will reduce driving range.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and se-
lect ECO position before going down a slope or
long grade. Overheated brakes may reduce brak-
ing performance and could result in loss of ve-
hicle control.
WARNING
• While driving on a slippery surface, be careful when braking or accelerating.
Abrupt braking or accelerating could
cause the wheels to skid, which could
result in an accident.
• If the brake pedal is depressed with the EV (Electric Vehicle) system OFF,
you may feel an increased brake pedal
effort and a decreased pedal stroke. If
the BRAKE warning light does not illu-
minate and the brake pedal feels like it
has returned to its normal state after
the EV system is started, this indicates
that there is no malfunction and the
vehicle can be operated normally.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, the
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes have dried.
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 the “Mainte-
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 brak-
ing or when braking on slippery surfaces. The sys-
tem detects the rotation speed at each wheel and
varies the brake fluid pressure to prevent 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 slippery 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 malfunction, 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.
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.
5-22Starting 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 shift lever is shifted into D (Drive) , ECO, orR (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. •
The predicted charging time displayed on
the meter and navigation system in-
creases when the Li-ion battery warmer
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 temperature is
below 32°F (0°C) uses more electricity and
affects vehicle range more than when us-
ing the heater when the temperature is
above 32°F (0°C) .
• Climate control performance is reduced
when using the Climate Ctrl. Timer or Re-
mote Climate Control while the Li-ion bat-
tery warmer operates. Set only the charg-
ing timer [End Time] when charging in cold
weather. The vehicle automatically deter-
mines when to start charging to fully
charge the Li-ion battery, even if the Li-ion
battery warmer operates. Charging ends
before the set end time if the Li-ion bat-
tery is fully charged.

primary latch is released.
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 (if so equipped):
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.
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 is the proper dis-
tance 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 mechanism:
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

Be careful not to clog the washer nozzleA. This
may cause improper windshield washer opera-
tion. If the nozzle is clogged, remove any objects
with a needle or small pin
B. Be careful not to
damage the nozzle. 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.
