NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the power switch to be placed
in the READY to drive position without the
use of the registered key.
If the power switch fails to place the vehicle
into the READY to drive position using the
registered key, it may be due to interfer-
ence caused by another registered key, an
automated toll road device or automated
payment device on the key ring. Restart the
EV system using the following procedure:
1. Leave the power switch in the ON posi- tion for approximately 5 seconds.
2. Place the power switch in the OFF posi- tion and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device
(which may have caused the interfer-
ence) separate from the registered key.
If this procedure allows the power
switch to be placed in the READY to drive
mode, NISSAN recommends placing the
registered key on a separate key ring to
avoid interference from other devices. • Make sure that the area around the ve-
hicle is clear.
• Check fluid levels such as coolant, brake fluid, and windshield-washer fluid as fre-
quently as possible.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position the seat and adjust the head restraints/headrests.
• Adjust the inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of the warning lights when the power switch is pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-14).
BEFORE STARTING THE EV SYSTEM
Starting and driving5-13

1. Confirm the parking brake is applied.
2. Confirm that the vehicle is in the P (Park)position.
When the power switch is placed in the
ON position, the EV is designed not to
operate unless the shif t lever is in the P
(Park) or N (Neutral) position.
The Intelligent Key must be carried
with you when operating the power
switch.
3. Depress the brake pedal and push the power switch to place the EV system in
the READY to drive position.
To place the vehicle in the READY to drive
position immediately, push and release
the power switch while depressing the
brake pedal with the power switch in any
position. The READY to drive indicator
light
in the meter illuminates.
4. To stop the EV system, push the P (Park) position switch on the shif t lever, and
place the power switch in the OFF
position.
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. The 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.
ELECTRIC SHIFT CONTROL
SYSTEM
This vehicle is electronically controlled to
produce maximum available power and
smooth operation.
The recommended operating procedures
for this vehicle are shown on the following
pages.
Starting the vehicle
1. Af ter placing the vehicle in the READY to drive position, fully depress the foot
brake pedal before moving the shif t lever
to the D (Drive) position.
The shif t lever of this vehicle is de-
signed so that the foot brake pedal
must be depressed before shif ting
from the P (Park) position to any driv-
ing position while the power switch is
in the ON position.
The shif t lever cannot be moved out of
the P (Park) position and into any of
the other positions if the power switch
is placed in the LOCK, OFF or ACC posi-
tion or if the Intelligent Key is
removed.

5-14Starting and driving

CAUTION
To prevent damage to the Li-ion bat-
tery: Do not store the vehicle in tem-
peratures below -13°F (-25°C) for over
seven days. If the outside temperature
is -13°F (-25°C) or less, the Li-ion battery
may freeze and it cannot be charged or
provide power to run the vehicle. Move
the vehicle to a warm location.
NOTE:
• Connect the charger to the vehicle and place the power switch in the OFF po-
sition when parking the vehicle if tem-
peratures may go below -4°F (-20°C).
For models with 40 kWh battery
model, this provides external power to
the Li-ion battery warmer (if so
equipped) when it operates and does
not discharge the Li-ion battery. Ve-
hicle driving range is reduced if the Li-
ion battery warmer (if so equipped) op-
erates (Li-ion battery temperature
approximately -4°F (-20°C) or colder)
while driving the vehicle. You may need
to charge the Li-ion battery sooner
than in warmer temperatures.
• The Li-ion battery requires more time to charge when the Li-ion battery
warmer (if so equipped) operates. • The predicted charging time displayed
on the meter and navigation system (if
so equipped) increases when the Li-ion
battery warmer (if so equipped)
operates.
• Vehicle range may be substantially re- duced in extremely cold conditions (for
example under -4°F (-20°C)).
• Using the climate control system to heat the cabin when outside tempera-
ture is below 32°F (0°C) uses more elec-
tricity and affects vehicle range more
than when using the heater when the
temperature is above 32°F (0°C).
• Climate control performance is re- duced when using the Climate Ctrl.
Timer or Remote Climate Control while
the Li-ion battery warmer (if so
equipped) operates (for models with
40 kWh battery model). Set only the
charging timer [End Time] when charg-
ing in cold weather. The vehicle auto-
matically determines when to start
charging to fully charge the Li-ion bat-
tery, even if the Li-ion battery warmer
operates. Charging ends before the set
end time if the Li-ion battery is fully
charged.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting
it into the key hole or use the remote key-
less entry key fob.
ANTIFREEZE
In the winter when it is possible that the
outside temperature will drop below 32°F
(0°C), check the antifreeze to ensure proper
winter protection. For additional informa-
tion, see “Cooling system” (P. 8-5).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery” (P. 8-9).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system. Refill
before operating the vehicle. For additional
information, see “Cooling system” (P. 8-5).
