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, prescrip-
tion, and illegal drugs) . Do not drive if your ability
to operate your vehicle is impaired by alcohol,
drugs, or some other physical condition.
WARNING
Do not operate the power switch while
driving the vehicle except in an emer-
gency. (The EV system shuts down when
the power switch is pushed 3 consecutive
times or the power switch is pushed and
held for more than 2 seconds.) If the EV
system stops while the vehicle is being
driven, this could lead to a crash and
serious injury.
Before operating the power switch, make sure
the vehicle is in the P (Park) position.
NISSAN INTELLIGENT KEY®

5-10Starting and driving

To shut off the EV system in an emergency situ-
ation while driving, perform the following proce-
dure.
• Rapidly push the power switch three consecu-tive 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 monitors
tire pressure of all tires. When the low tire pres-
sure warning light is lit, and the CHECK TIRE
PRESSURE warning appears on the vehicle in-
formation display, one or more of your tires is
significantly under-inflated. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate 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 additional information, refer to
“Warning lights, indicator lights and audible re-
minders” in the “Instruments and controls” sec-
tion 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 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 replacing a wheel without the TPMS such as the spare tire, TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on after 1 minute. Have your tires re-
placed and/or TPMS system reset as
soon as possible. It is recommended
that you visit a NISSAN certified LEAF
dealer for these services.

5. Remove the protective capAof the hose
and screw the hose securely onto the tire
valve. Make sure that the pressure release
valve
Bis securely tightened. 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” position.
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 driv-
er’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 pressure 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
inflating the tire. The pressure gauge is
indicating the pressure inside the seal-
ant can. When the sealant has been in-
jected 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 repair
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 dam- aged tire while it is being inflated be-
cause of the risk of the rupture. If there
are any cracks or bumps, turn the com-
pressor 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 certi-
fied 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 specified 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
protective 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 re-
pair 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 minutes or 2 miles (3 km) at a speed below 50 mph
(80 km/h) . 9. After driving, make sure that the air compres-
sor switch is in the OFF position, then screw
the hose securely onto the tire valve. Check
the tire pressure with the pressure gauge.
Temporary repair is completed if the tire pres-
sure 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 repair kit.Itis
recommended that you visit a NISSAN cer-
tified LEAF dealer.
The sealant bottle and hose cannot be re-
used to repair another punctured tire. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer to purchase replace-
ments.
After repairing tire:
It is recommended that you visit a NISSAN certi-
fied LEAF dealer for tire repair/replacement as
soon as possible.
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 Emergency
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.
• 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.
• If you used the Emergency Tire Sealant to repair a minor tire puncture, a
NISSAN certified LEAF dealer will also
need to replace the TPMS sensor in
addition to repairing or replacing the
tire.
