brake NISSAN LEAF 2017 1.G Repair Manual

TOWING RECOMMENDED BY
NISSAN
NISSAN recommends that your vehicle be towed
with the driving (front) wheels off the ground or
that the vehicle be placed on a flatbed truck as
illustrated.
CAUTION
• Never tow with the front wheels on the ground or four wheels on the ground
(forward or backward) , as this may
cause serious and expensive damage
to the motor. • When towing this vehicle with the rear
wheels on the ground (if you do not
use towing dollies): Always release
the parking brake.
NOTE:
If your vehicle cannot be moved because
the vehicle cannot to be shifted to the N
(Neutral) position, please refer to the LEAF
Roadside Assistance Guide which is lo-
cated at www.NISSANUSA.com. If your ve-
hicle cannot be moved because the parking
brake cannot be released, refer to “Parking
brake” in the “Starting and driving” section
of this manual.
VEHICLE RECOVERY (FREEING A
STUCK VEHICLE)
WARNING
To avoid vehicle damage, serious per-
sonal injury or death when recovering a
stuck vehicle:
• Contact a professional towing service to recover the vehicle if you have any
questions regarding the recovery pro-
cedure.
• Tow chains or cables must be attached only to main structural members of the
vehicle.
• Do not use the vehicle tie-downs to tow or free a stuck vehicle.
• Only use devices specifically designed for vehicle recovery and follow the
manufacturer’s instructions.
• Always pull the recovery device straight out from the front of the ve-
hicle. Never pull at an angle.
• Route recovery devices so they do not touch any part of the vehicle except the
attachment point.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
• The accumulation of moisture-retaining dirt anddebris in body panel sections, cavities, and
other areas.
• Damage to paint and other protective coatings caused by gravel and stone chips or minor
traffic accidents.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the ve-
hicle body underside can accelerate corrosion.
Wet floor coverings will not dry completely inside
the vehicle, and should be removed for drying to
avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas where
the temperatures stay above freezing, where at-
mospheric pollution exists, or where road salt is
used.
Temperature
A temperature increase will accelerate the rate of
corrosion to those parts which are not well ven-
tilated.
Air pollution
Industrial pollution, the presence of salt in the air
in coastal areas, or heavy road salt use will accel-
erate the corrosion process. Road salt will also
accelerate the disintegration of paint surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
• Wash and wax your vehicle often to keep thevehicle clean.
• Always check for minor damage to the paint and repair it as soon as possible.
• Keep drain holes at the bottom of the doors open to avoid water accumulation.
• Check the underbody for accumulation of sand, dirt or salt. If present, wash with water as soon
as possible.
CAUTION
• NEVER remove dirt, sand or other de- bris from the passenger compartment
by washing it out with a hose. Remove
dirt with a vacuum cleaner.
• Never allow water or other liquids to come in contact with electronic com-
ponents inside the vehicle as this may
damage them.
Chemicals used for road surface deicing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
such as the brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and corro-
sion, which may be required in some areas, it is
recommended that you consult a NISSAN certi-
fied LEAF dealer.

keeps the motor hood from opening when the
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
5,000 miles (8,000 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.
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. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, it is recom-
mended that you visit 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, it is recommended that you visit a NISSAN
certified LEAF dealer for this service.
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
Maintenance and do-it yourself8-3

smoothly and that the locks (if so equipped) hold
securely in all latched positions.
Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating properly.
Windshield defroster: Check that the air emits
from the defroster outlets properly and in suffi-
cient quantity when operating the heater or air
conditioner.
Windshield wiper and washer*: Check that
the wipers and washers operate properly and
that the wipers do not streak.
Under hood and vehicle
The maintenance items listed here should be
checked periodically.
12-volt battery (for serviceable battery)*:
Check the fluid level in each cell. It should be
between the MAX and MIN lines. Vehicles oper- ated in high temperatures or under severe condi-
tions require frequent checks of the 12–volt bat-
tery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1.
Installation or extended use of elec-
tronic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the “MAX” and “MIN” lines
on the reservoir.
Coolant level*: Check the coolant level when
the motor compartment is cold.
Fluid leaks: Check under the vehicle for water
or other fluid leaks after the vehicle has been
parked for a while. Water dripping from the air
conditioner after use is normal. If you should notice any leaks, check for cause and have it
corrected immediately.
Radiator and hoses:
Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure that
the hoses have no cracks, deformation, rot or
loose connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan and frame. At
the end of winter, the underbody should be thor-
oughly flushed with plain water, being careful to
clean those areas where mud and dirt may accu-
mulate. For additional information, refer to
“Cleaning exterior” in the “Appearance and care”
section of this manual.
Windshield-washer fluid*: Check that there is
an adequate amount of fluid in the reservoir.
8-4Maintenance and do-it yourself

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions that should be closely observed.
WARNING
• The EV system uses high voltage up to approximately DC 400 volt. The system
can be hot during and after starting
and when the vehicle is shut off. Be
careful of both the high voltage and
the high temperature. Obey the labels
that are attached to the vehicle.
• Never disassemble, remove or replace high-voltage parts and cables as well
as their connectors. High-voltage
cables are colored orange.
• Disassembling, removing or replacing those parts or cables can cause severe
burns or electric shock that may result
in serious injury or death. The vehicle
high-voltage system has no user ser-
viceable parts. Take your vehicle to the
NISSAN certified LEAF dealer for any
necessary maintenance. • Park the vehicle on a level surface,
apply the parking brake securely and
chock the wheels to prevent the ve-
hicle from moving. Push the P (Park)
position switch on the shift lever or
place the vehicle into the N (Neutral)
position.
• If you must work with the EV (Electric vehicle) system is turned on, keep
hands, clothing, hair and tools away
from moving fans and any other mov-
ing parts.
• Make sure that the power switch is in the OFF or LOCK position when per-
forming any part replacement or re-
pairs.
• It is advisable to secure or remove any loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
• Always wear eye protection whenever you work on your vehicle.
• Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
• Keep smoking materials, flames and sparks away from the 12-volt battery.
CAUTION
• Do not work under the hood while the motor compartment is hot. Push the
power switch in the OFF position and
wait until it cools down.
• Avoid direct contact with used coolant. Improperly disposed coolant and/or
other vehicle fluids can damage the
environment. Always conform to local
regulations for the disposal of vehicle
fluids.
• Never connect or disconnect the bat- tery or any transistorized component
while the power switch is in the ON
position.
• Your vehicle is equipped with an auto- matic cooling fan. It may come on at
any time without warning, even if the
power switch is not in the ACC, ON or
READY to drive position. To avoid in-
jury, always disconnect the negative
12-volt battery cable before working
near the fan.
• Before performing any electrical main- tenance work on the vehicle such as
the battery, fuses or bulb replacement,
confirm the following:
– The charge connector is removedfrom the vehicle.

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, refer to
the maintenance log section of your NISSAN
Service and Maintenance Guide.
BRAKES
8-16Maintenance and do-it yourself

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 Dynamic Control
(VDC) system, ground clearance, body-
to-tire clearance, tire chain clearance,
speedometer calibration, headlight
aim and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.
• If your vehicle was originally equipped with four tires that were the same size
and you are only replacing two of the
four tires, install the new tires on the
rear axle. Placing new tires on the front
axle may cause loss of vehicle control
in some driving conditions and cause
an accident and personal injury. • If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade
vehicle handling characteristics, affect
the VDC system and/or interference
with the brake discs. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. For additional information on
wheel-off set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section of
this manual.
• When replacing a wheel without the TPMS such as the spare tire, TPMS will
not function when a wheel is replaced,
the TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. It is rec-
ommended that you visit a NISSAN
certified LEAF dealer for this service.
• Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
• The TPMS sensor may be damaged if it is not handled correctly. Be careful
when handling the TPMS sensor. • When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a NISSAN
certified LEAF dealer for ID registra-
tion.
• Do not use a valve stem cap that is not specified by NISSAN. The valve stem
cap may become stuck.
• Be sure that the valve stem caps are correctly fitted. Otherwise the valve
may be clogged up with dirt and cause
a malfunction or loss of pressure.
• Do not install a damaged or deformed wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
• The use of retread tire is not recom- mended.
• For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
