Starting and driving5-171

To shut off the EV system in an emergency
situation while driving, perform the follow-
ing procedure.
• Rapidly push the power switch three con-secutive times in less than 1.5 seconds, or
• Push and hold the power switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires. When the low
tire pressure warning light is lit, and the “Tire
Pressure Low — Add Air” warning appears
on the vehicle information display, 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 warn-
ing light. This system will activate only
when the vehicle is driven at speeds above
16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights
and audible reminders” in the “Instruments
and controls” section and “Tire Pressure
Monitoring System (TPMS)” in the “Starting
and driving” section of this manual.
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 underinflated 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
light still illuminates while driving af-
ter adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
pair it as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit a certified
LEAF dealer for this service.

5. Remove the protective capOAof the
hose and screw the hose securely onto
the tire valve. Make sure that the pres-
sure release valve
OBis securely tight-
ened. Make sure that the air compressor
switch is in the OFF (O) position, and
then insert the power plug into the
power outlet in the vehicle. 6. Push the power switch to the ACC posi-
tion. Then turn the compressor switch
to the ON (−) position and inflate the tire
up to the pressure that is specified on
the Tire and Loading Information label
affixed to the driver’s side center pillar if
possible, or to the minimum of 26 psi
(180 kPa). Turn the air compressor off
briefly in order to check the tire pressure
with the pressure gauge.
If the tire is inflated to higher than the
specified pressure, lower the tire pres-
sure by releasing air with the pressure
release valve.
NOTE:
The compressor tire pressure gauge
may show a pressure reading of 87 psi
(600 kPa) for about 30 seconds while in-
flating the tire. The pressure gauge is in-
dicating the pressure inside the sealant
can. When the sealant has been injected
into the tire the pressure gauge will drop
and indicate actual tire pressure.
WARNING
To avoid serious personal injury while
using the emergency tire puncture re-
pair kit:
• Securely tighten the compressor
hose to the tire valve. Failure to do so
can cause the sealant to spray into
the air and get into your eyes or on
the skin.
• Do not stand directly beside the
damaged tire while it is being in-
flated because of the risk of the rup-
ture. If there are any cracks or bumps,
turn the compressor off
immediately.

6-8In case of emergency

If the tire pressure does not increase to26
psi (180 kPa) within 10 minutes, the tire
may be seriously damaged and the tire
cannot be repaired with this tire repair
kit. It is recommended that you visit a
NISSAN certified LEAF dealer.
7. When the tire pressure is at the specified amount, turn the air compressor off. If
the tire cannot be inflated to the speci-
fied amount, the air compressor can be
turned off at the minimum of 26 psi (180
kPa). Remove the power plug from the
power outlet and quickly remove the
hose from the tire valve. Attach the pro-
tective cap and valve cap. Properly stow
the emergency tire puncture repair kit in
the cargo area.
CAUTION
To avoid serious personal injury when
stowing the emergency tire puncture
repair kit:
• Keep the sealant bottle screwed into
the compressor. Failure to do so can
cause the sealant to spray into the air
and get into your eyes or on the skin.
8. Immediately drive the vehicle for 10 min- utes or 2 miles (3 km) at a speed below
50 mph (80 km/h). 9. Af ter driving, make sure that the air
compressor switch is in the OFF posi-
tion, then screw the hose securely onto
the tire valve. Check the tire pressure
with the pressure gauge. Temporary re-
pair is completed if the tire pressure
does not drop.
Make sure the pressure is adjusted to
the pressure that is specified on the Tire
and Loading Information label before
driving.
10. If the tire pressure drops, repeat the steps from 5 to 9. If the pressure drops
again or under 19 psi (130 kPa), the tire
cannot be repaired with this tire re-
pair kit. If the tire cannot be repaired,
the driver should not drive on it any
further. The car should be towed to the
nearest dealership.
The sealant bottle and hose cannot be
reused to repair another punctured tire.
It is recommended that you visit a
NISSAN certified LEAF dealer to pur-
chase replacements.
Af ter repairing tire
It is recommended that you visit a NISSAN
certified LEAF dealer for tire repair/
replacement as soon as possible.
WARNING
• Af ter using Genuine NISSAN Emer-
gency Tire Sealant to repair a minor
tire puncture, do not drive the vehicle
at speeds faster than 50 mph (80
km/h).

be checked periodically.
12-volt battery (except for maintenance
free batteries)*: Check the fluid level in
each cell. The fluid should be at the bottom of the filler opening. Vehicles operated in
high temperatures or under severe condi-
tions require frequent checks of the 12–volt
battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the EV system 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 high voltage parts are cold. Make
sure that the coolant level is between the
MAX and MIN lines on the reservoir.
Fluid leaks: Check under the vehicle for
water or other fluid leaks af ter the vehicle
has been parked for a while. Water dripping from the air conditioner af ter 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.

there is an adequate amount of fluid in the
reservoir.
8-4Maintenance and do-it yourself

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions 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 af ter
starting and when the vehicle is shut
off. Be careful of both the high volt-
age and the high temperature. Obey
the labels that are attached to the
vehicle.
• Never disassemble, remove or re-
place high-voltage parts and cables
as well as their connectors. High-
voltage cables are colored orange.
• Disassembling, removing or replac-
ing 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 serviceable parts. It is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer for any necessary
maintenance. •
