NISSAN INTELLIGENT KEY®
OPERATING RANGE OF THE DOOR
LOCK/UNLOCK FUNCTION
The Intelligent Key functions can only be used
when the Intelligent Key is within the specified
operating range from the request switch
1.
When the Intelligent Key battery is discharged or
strong radio waves are present near the operat-
ing location, the Intelligent Key system’s operat-
ing range becomes narrower, and the Intelligent
Key may not function properly.The operating range is within 31.50 in (80 cm)
from each request switch
1.
If the Intelligent Key is too close to the door glass,
handle or rear bumper, the request switches may
not function.
When the Intelligent Key is within the operating
range, it is possible for anyone who does not
carry the Intelligent Key to push the request
switch to lock/unlock the doors including the rear
hatch.
DOOR LOCKS/UNLOCKS
PRECAUTION
• Do not push the door handle request switch
with the Intelligent Key held in your hand as

• After locking with the door handle request
switch, verify the doors are securely locked by
testing them.

Pre-driving checks and adjustments3-19

When the shift lever is shifted into the R (Re-
verse) position, the monitor display shows a rear-
ward view from the vehicle.
WARNING
Failure to follow the warnings and in-
structions for proper use of the Rear View
Monitor could result in serious injury or
death.
• The RearView Monitor is a conve-
nience but it is not a substitute for
proper backing. Always turn and look
out the windows, and check mirrors to
be sure that it is safe to move before
operating the vehicle. Always back up
slowly.
• The system is designed as an aid to the
driver in showing large stationary ob-
jects directly behind the vehicle, to
help avoid damaging the vehicle.
• The system will not detect small ob-
jects below the bumper, and may not
detect objects close to the bumper or
on the ground.
• The system cannot completely elimi-
nate blind spots and may not show
every object.• Underneath the bumper and the corner
areas of the bumper cannot be viewed
on the RearView Monitor because of
its monitoring range limitation. The
system will not show objects below
the bumper, and may not show objects
close to the bumper or on the ground.
• Objects viewed in the RearView Moni-
tor differ from actual distance because
a wide-angle lens is used.
• Objects in the RearView Monitor will
appear visually opposite than when
viewed in the rear view and outside
mirrors.
• Make sure that the hatch is securely
closed when backing up.
• Do not put anything on the rearview
camera. The rearview camera is in-
stalled on top of the hatch.
• When washing the vehicle with high
pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing wa-
ter condensation on the lens, a mal-
function, fire or an electric shock.
• Do not strike the camera. It is a preci-
sion instrument. Otherwise, it may
malfunction or cause damage result-
ing in a fire or an electric shock.
CAUTION
There is a plastic cover over the camera.
Do not scratch the cover when cleaning
dirt or snow from the cover.

WARNING
• Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves or
others through inadvertent operation
of the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle 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 sliding or
shifting. Do not place cargo higher
than the seatbacks. In a sudden stop or
collision, unsecured cargo could cause
personal injury.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the ve-
hicle 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 infla-tion 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 possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces power efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination 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 mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction 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,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing 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
• The TPMS will activate only when the vehicle 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) .
• The low tire pressure warning light does not
automatically turn off when the tire pressure is
adjusted. After the tire is inflated to the recom-
mended pressure, the vehicle must be driven at
speeds above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure warning
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

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®

start the EV (Electric Vehicle) system without
taking the key out of the pocket or purse. The
operating environment and/or conditions may af-
fect Intelligent Key system operation.
Some indicators and warnings for operation are
displayed on the vehicle information display in the
lower display. See “Vehicle information display” in
the “Instruments and controls” section.)
