gauge to check the tire pressure.
The Check tire Pressure warning is active as
long as the low tire pressure warning light
remains illuminated.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “5. Starting
and driving” section and “Tire Pressure Monitor-
ing System (TPMS)” in the “6. In case of
emergency” section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the power switch is
placed in the ON position. The light will remain
on after the 1 minute. Have the system checked
by a NISSAN certified LEAF dealer. The Check
tire Pressure warning does not appear if the low
tire pressure warning light illuminates to indicate
a TPMS malfunction.
For additional information, see “Dot matrix liquid
crystal display” later in this section and “Tire
Pressure Monitoring System (TPMS)” in the “5.
Starting and driving” section.

WARNING
The tire replacement indicator is not a
substitute for regular tire checks, in-
cluding tire pressure checks. See
“Changing wheels and tires” in the “8.
Maintenance and do-it-yourself” sec-
tion. Many factors including tire infla-
tion, alignment, driving habits and road
conditions affect tire wear and when
tires should be replaced. Setting the
tire replacement indicator for a certain
driving distance does not mean your
tires will last that long. Use the tire
replacement indicator as a guide only
and always perform regular tire checks.
Failure to perform regular tire checks,
including tire pressure checks could
result in tire failure. Serious vehicle
damage could occur and may lead to a
collision, which could result in serious
personal injury or death.
2. 3. 4. “Other” indicator
These indicators appears when the customer
set distance comes for checking or replacing
maintenance items other than the tires. Other
maintenance items can include such things as
the tire rotation. You can set or reset the
distance for checking or replacing the items.
(See “Trip computer” earlier in this section.) For
scheduled maintenance items and intervals, see
your NISSAN Service and Maintenance Guide.

pressure warning light. Use a tire pressure
gauge to check the tire pressure.
. The Check tire Pressure warning appears on
the dot matrix liquid crystal display when the
low tire pressure warning light is illuminated
and low tire pressure is detected. The
Check tire Pressure warning turns off when
the low tire pressure warning light turns off.
The Check tire Pressure 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 vehicle
and the outside temperature. A low outside
temperature can decrease 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.
For additional information, see “Low tire pres-
sure warning light” in the “2. Instruments and
controls” section and “Tire Pressure Monitoring
System (TPMS)” in the “6. In case of emer-
gency” section.

.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 temporarily
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.

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
position switch on the selector 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
indicators 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 3 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 after 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 external
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 an electrical equipment is being used inor near the vehicle.
— There is a malfunction in the TPMS system.
— There is a malfunction in the horn or hazard indicators.
— If the Easy Fill Tire Alert does not operate due to TPMS interference, move the
vehicle about 3 ft (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 ROLL-
OVER

inflated tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage. See
“Wheels and tires” in the “8. Maintenance and
do-it-yourself” section of this manual.
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.

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 pres-
sure 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
pressure, 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
pressure warning light will flash for
approximately 1 minute. The light
will remain on after 1 minute. Con-
tact a NISSAN certified LEAF dealer
as soon as possible for tire replace-
ment and/or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS. .
If you used the Emergency Tire
Sealant to repair a minor tire punc-
ture, your NISSAN certified LEAF
dealer will also need to replace the
TPMS sensor in addition to repair-
ing or replacing the tire.
. NISSAN recommends using only
NISSAN Genuine Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure.
