CAUTION
• The TPMS may not function properly when the wheels are equipped with
tire chains or the wheels are buried in
snow.
• Do not place metalized film or any metal parts (antenna, etc.) on the win-
dows. This may cause poor reception
of the signals from the tire pressure
sensors, and the TPMS will not func-
tion properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to illu-
minate. Some examples are:
• Facilities or electric devices using similar radio frequencies that are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near the vehicle.
• The low tire pressure warning light may illumi- nate in the following cases: – If the vehicle is equipped with a wheel and tire without TPMS.
– If the TPMS has been replaced and the ID has not been registered. – If the wheel is not originally specified by
NISSAN.

TPMS with Easy-Fill Tire Alert
When tire pressure is low, the low tire pressure
warning light illuminates.
This vehicle provides visual and audible signals to
help you inflate the tires to the recommended
COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and push the P (Park) position switch on the shift lever.
3. Place the power switch in the ON position. Do not place in the READY to drive mode.
Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indica-
tors stop flashing.
4. Perform the above steps for each tire.
• If the tire is over-inflated more than approxi- mately 4 psi (30 kPa) , the horn beeps and the
hazard indicators flash three times. To correct
the pressure, push the core of the valve stem on
the tire briefly to release pressure. When the
5-4Starting and driving

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 additional information, refer to “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. It is recommended that you visit a
NISSAN certified LEAF dealer for this service.
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.
Starting and driving5-23

The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC system helps to per-
form the following functions.
• Controls brake pressure to reduce wheel slip onone 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 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.
For additional information, refer to “Vehicle Dy-
namic Control (VDC) warning light” and “Vehicle
Dynamic Control (VDC) OFF indicator light” in
the “Instruments and controls” section of this
manual.
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
non slipping wheel. The
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 power switch
is placed in the OFF position then back to the ON
position.
The computer has a built-in diagnostic feature
that tests the system each time you start the EV
and move the vehicle forward or in reverse at a
slow speed. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an indica-
tion of a malfunction.
WARNING
• The VDC system is designed to help the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving tech-
niques. Reduce vehicle speed and be
especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully.
• Do not modify the vehicle’s suspen- sion. If suspension parts such as shock
absorbers, struts, springs, stabilizer
bars, bushings and wheels are not
NISSAN recommended for your ve-
hicle or are extremely deteriorated the
VDC system may not operate properly.

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.
