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

Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will can-
cel automatically and “Malfunction: See
Owner’s Manual” will appear in the vehicle
information display. If “Malfunction: See
Owner’s Manual” appears in the vehicle in-
formation display, pull off the road to a safe
location and stop the vehicle. Place the
shif t lever in the P (Park) position and the
power switch in the OFF position and re-
start the EV system. If “Malfunction: See
Owner’s Manual” continues to appear in
the vehicle information display, have the
system checked. It is recommended that
you visit a NISSAN certified LEAF dealer for
this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the LDW sys-
tem is located above the inside mirror. To
keep the proper operation of the LDW sys-
tem and prevent a system malfunction, be
sure to observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the camera unit. • Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. If the camera unit is
damaged due to an accident, it is recom-
mended that you visit a NISSAN certified
LEAF dealer.

Temporary disabled status at high
temperature:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then the
I-LI system is turned on, the I-LI system
may be deactivated automatically and the
following message will appear on the ve-
hicle information display: “Unavailable: High
Cabin Temperature.” When the interior
temperature is reduced, the system will re-
sume operating automatically.
SYSTEM MALFUNCTION
If the I-LI system malfunctions, it will cancel
automatically. The I-LI indicator (orange)
will illuminate and “Malfunction: See Own-
er’s Manual” warning message will appear
in the display.
If the I-LI indicator (orange) illuminates in
the display, pull off the road to a safe loca-
tion and stop the vehicle. Turn the EV sys-
tem off and restart the EV system. If the I-LI
indicator (orange) continues to illuminate,
have the I-LI system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the I-LI system
is located above the inside mirror. To keep
the proper operation of the I-LI system and
prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the camera unit. • Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. If the camera unit is
damaged due to an accident, it is recom-
mended that you visit a NISSAN certified

NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the EV
system off and restart the EV system. If the
indicators continue to appear, have the
system checked. It is recommended that
you visit a NISSAN certified LEAF dealer for
this service.
SYSTEM MAINTENANCE
The two radar sensorsO1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the radar sensors.
Do not strike or damage the area around
the radar sensors. It is recommended that
you visit a NISSAN certified LEAF dealer if
the area around the radar sensors is dam-
aged due to a collision.

STEERING ASSIST
WARNING
Failure to follow the warnings and in-
structions for proper use of the Steer-
ing Assist could result in serious injury
or death. •
The Steering Assist is not a replace-
ment for proper driving procedures
and is not designed to correct care-
less, inattentive or absent-minded
driving. The Steering Assist will not
always steer the vehicle to keep it in
the lane. It is not designed to prevent
loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely,
keep the vehicle in the traveling lane,
and be in control of the vehicle at all
times.
• As there is a performance limit to the
Steering Assist’s capability, never
rely solely on the system. The Steer-
ing Assist does not function in all
driving, traffic, weather, and road
conditions. Always drive safely, pay
attention to the operation of the ve-
hicle, and manually control your ve-
hicle appropriately.
• The Steering Assist is intended for
use on well-developed freeways or
highways with gentle (moderate)
curves. To avoid risk of an accident,
do not use this system on local or
non-highway roads.
