WARNING
• Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be lef t alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot, sunny
days, temperatures in a closed ve-
hicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces power efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately oneminute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
Additional information
• When using a wheel without the TPMS
such as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

• The low tire pressure warning light doesnot automatically turn off when the tire
pressure is adjusted. Af ter the tire is in-
flated to the recommended pressure, the
vehicle must be driven at speeds above
16 mph (25 km/h) to activate the TPMS
and turn off the low tire pressure warning
light. Use a tire pressure gauge to check
the tire pressure.
• The “Tire Pressure Low - Add Air” warning also appears on the vehicle information
display when the low tire pressure warn-
ing light is illuminated and low tire pres-
sure is detected. The “Tire Pressure Low -
Add Air” warning turns off when the low
tire pressure warning light turns off.
• The “Tire Pressure Low - Add Air” warning appears each time the power switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
• The “Tire Pressure Low - Add Air” warning does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction. • Tire pressure rises and falls depending on
the heat caused by operation of the ve-
hicle and the outside temperature. Do
not reduce the tire pressure af ter driving
because the tire pressure rises af ter driv-
ing. Low outside temperature can lower
the temperature of the air inside the tire,
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates in low ambient
temperature, check the tire pressure for
all four tires.
• The pressure of all tires can also be checked on the display screen. The order
of the tire pressure figures displayed on
the screen does not correspond with the
actual order of the tire position.
For additional information, see “Low tire
pressure warning light” (P. 2-20) and “Tire
Pressure Monitoring System (TPMS)” (P. 6-3).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before 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 under-inflated tires may
permanently 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 in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light off. If the tire is
flat, repair it as soon as possible. For
additional information, see “Flat tire”
(P. 6-3).
Starting and driving5-5

•When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
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
windows. This may cause poor re-
ception of the signals from the tire
pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate. 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
illuminate 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. FCC Notice:

TPMS with Easy-Fill Tire Alert
When tire pressure is low, the low tire pres-
sure 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 shif t lever.
3. Place the power switch in the ON posi- tion. Do not place in the READY to drive
mode.
Operation:
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 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 pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate the tire, it indicates
that the Easy-Fill Tire Alert is not
operating.
• The TPMS will not activate the Easy-Fill
Tire Alert under the following conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire, such as those using a power
socket.
– If electrical equipment is being used in or near the vehicle.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– If the Easy-Fill Tire Alert does not op- erate due to TPMS interference,
move the vehicle about 3 f t (1 m)
backward or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers because these driving
practices could cause you to lose control of
your vehicle. As with any vehicle, a loss of
control could result in a collision with
other vehicles or objects or cause the ve-
hicle to rollover, particularly if the loss of
control causes the vehicle to slide side-
ways. Be attentive at all times, and avoid
driving when tired. Never drive when under
the influence of alcohol or drugs (including
prescription or over-the-counter drugs
which may cause drowsiness). Always
wear your seat belt as outlined in “Seat
belts” (P. 7-6), and also instruct your passen-
gerstodoso.
Seat belts help reduce the risk of injury in col-
lisions and rollovers. In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seat belt.
Starting and driving5-7

OFF-ROAD RECOVERY
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. Please note that this procedure is only
a general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steeringwheel with both hands and try to hold a
straight course.
4. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the ve-
hicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until the vehicle speed is
reduced. 6. When it is safe to do so, gradually turn
the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to
stay in the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based
on vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in
a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially
at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, see
“Wheels and tires” (P. 8-25).
If a tire rapidly loses air pressure or “blows-
out” while driving, maintain control of the
vehicle by following the procedure below.
Please note that this procedure is only a general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pres-
sure. Losing control of the vehicle may
cause a collision and result in personal
injury.
• The vehicle generally moves or pulls
in the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator
pedal.
• Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle.
5-8Starting and driving

4. Gradually steer the vehicle to a safe lo-cation off the road and away from traffic
if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service
to change the tire. For additional infor-
mation, see “Flat tire” (P. 6-3).
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving af ter drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an ac-
cident, alcohol can increase the sever-
ity of the injury. NISSAN is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol-related accidents. Although the lo-
cal laws vary on what is considered to be
legally intoxicated, the fact is that alcohol
affects all people differently and most
people underestimate the effects of
alcohol.
Remember, drinking and driving don’t mix!
That is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Do
not drive if your ability to operate your ve-
hicle is impaired by alcohol, drugs, or some
other physical condition.
WARNING
• Do not operate the power switch
while driving the vehicle except in an
emergency. (The EV system shuts
down when the power switch is
pushed three consecutive times or
the power switch is pushed and held
for more than 2 seconds.) If the EV
system stops while the vehicle is be-
ing driven, this could lead to a crash
and serious injury.
• When turning off the power switch,
make sure to shif t the shif t lever to
the P (Park) position even if the ve-
hicle is maintaining a stop and hold
using the e-pedal. This will prevent
the vehicle from moving or rolling
unexpectedly, which could result in
serious personal injury or property
damage.
Before operating the power switch, make
sure the vehicle is in the P (Park) position.
