2014 NISSAN LEAF warning light

•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 the
specified 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
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.
5-22Starting and driving

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 the “Instruments 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

The flasher can be actuated with the power
switch in any position.
Some state laws may prohibit the use of
the hazard warning flasher switch while
driving.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires. When the low tire pressure warn-
ing light is lit, and the CHECK TIRE PRESSURE
warning appears on the vehicle information dis-
play, 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 warning
light. This system will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h) . For more details, see “Warning/
indicator lights and audible reminders” in the
“Instruments and controls” section and “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” section.
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment manu-
facturer for the possible influences be-
fore 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 perma-
nently 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 injury. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light
OFF. If the light still illuminates while
driving after adjusting the tire pres-
sure, a tire may be flat. If you have a
flat tire, repair it as soon as possible.
• When a wheel is replaced, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on after 1 minute. Contact a
NISSAN certified LEAF dealer as soon
as possible for tire replacement
and/or system resetting.
FLAT TIRE
In case of emergency6-3

• Replacing tires with those not origi-
nally specified by NISSAN could affect
the proper operation of the TPMS.
• If you used the Emergency Tire Sealant
to repair a minor tire puncture, your
NISSAN certified LEAF dealer will also
need to replace the TPMS sensor in
addition to repairing or replacing the
tire.
• NISSAN recommends using only
NISSAN Genuine Emergency Tire Seal-
ant provided with your vehicle. Other
tire sealants may damage the valve
stem seal which can cause the tire to
lose air pressure.
REPAIRING FLAT TIRE
WARNING
•
After using Emergency Tire Sealant to
repair a minor tire puncture, do not
drive the vehicle at speeds faster than
50 MPH (80 km/h) .•
Immediately after using the Emer-
gency Tire Sealant to repair a minor
tire puncture, take your vehicle to a
NISSAN certified LEAF dealer to in-
spect, and repair or replace the tire.
The Emergency Tire Sealant cannot
permanently seal a punctured tire.
Continuing operation of the vehicle
without a permanent tire repair can
lead to a crash.
•
If you used the Emergency Tire Sealant
to repair a minor tire puncture, your
NISSAN certified LEAF dealer will also
need to replace the TPMS sensor in
addition to repairing or replacing the
tire.
•
NISSAN recommends using only
NISSAN Genuine Emergency Tire Seal-
ant provided with your vehicle. Other
tire sealants may damage the valve
stem seal which can cause the tire to
lose air pressure.
This vehicle does not have a spare tire. The
emergency tire puncture repair kit (Emergency
Tire Sealant) is supplied with the vehicle insteadof a spare tire. It can be used to temporarily repair
minor tire punctures.
If possible, have the vehicle towed to a facility that
can repair or replace the flat tire. Using the emer-
gency tire puncture repair kit may cause a mal-
function of the tire pressure sensor and cause the
low tire pressure warning light to illuminate.
If you have a flat tire, follow the instructions be-
low.
CAUTION
•
To avoid the emergency tire puncture
kit being damaged during storage or
use:
–
Only use the emergency tire punc-
ture repair kit on your vehicle. Do
not use it on other vehicles.
–
Only use the kit to inflate the tires of
your vehicle and to check the vehi-
cle’s tire pressure.
–
Only plug the compressor into a 12-
volt DC car power point.
–
Keep the kit free of water and dirt.
–
Do not disassemble or modify the
kit.
–
Do not drop the kit or allow hard
impacts to the kit.
6-4In case of emergency

Before using emergency tire puncture
repair kit
• If any foreign object (for example, a screw or
nail) is embedded in the tire, do not remove it.
• Check the expiration date of the sealant (shown
on the label attached to the bottle) . Never use a
sealant whose expiration date has passed.
Repairing tire:
WARNING
Observe the following precautions when
using the tire repair compound.
•
Swallowing the compound is danger-
ous. Immediately drink as much water
as possible and seek prompt medical
assistance.
•
Rinse well with lots of water if the
compound comes into contact with
skin or eyes. If irritation persists, seek
prompt medical attention.
•
Keep the repair compound out of the
reach of children.•
The emergency repair compound may
cause a malfunction of the tire pres-
sure sensors and cause the low tire
pressure warning light to illuminate.
Have the tire pressure sensor replaced
as soon as possible.
1. Take out the speed restriction sticker from the
air compressor, then put it in a location where
the driver can see it while driving.
CAUTION
Do not put the speed restriction label on
the steering wheel pad, the speedometer
or the warning light locations.

keep the READY to drive position over 20
minutes to charge the 12-volt battery.
11. Replace the vent caps (if so equipped) . Be
sure to dispose of the cloth used to cover
the vent holes because it may be contami-
nated with corrosive acid.
12. If necessary, connect the vehicle to a charg-
ing station or EVSE (Electric Vehicle Supply
Equipment) to charge the Li-ion battery.
(See “Charge” section.) The vehicle can not
be driven until the Li-ion battery is charged.
NOTE:
If it is not possible to turn the system ON by
following this procedure, contact a NISSAN
certified LEAF dealer immediately.If the power limitation indicator light
illumi-
nates, the traction motor output is limited result-
ing in reduced vehicle speed. Stop the vehicle in
a safe location before the Li-ion battery becomes
completely discharged and no power is available
to drive the vehicle. Contact Roadside assis-
tance; see your NISSAN Warranty Information
Booklet.
If possible, place the power switch in the OFF
position while waiting for assistance to prevent
discharging the 12-volt battery.
